I'm not sure what the author of the book you cite might refer to, but it's true that quantum mechanics allows the creation of temporary virtual particles from nothing. Some popular science theories have indeed suggested that the big bang might amount to little more than an unusually big vacuum fluctuation from which the matter and energy that makes up the universe emerged. Such an event would be incredibly unlikely, but, given limitless time, might nonetheless be expected to occur eventually. This could be taken to imply that the entire universe is virtual, composed of matter and energy that only exist temporarily. — Ilmari Karonen ( talk) 15:17, 1 January 2006 (UTC)
Interesting... and so if the universe was indeed virtual (which I think it is)there would be no need for anything else than a vacum besides the virtual matter and energy?-- Cosmic girl 17:45, 1 January 2006 (UTC)

Darwin stresses that the most formidable obstacle to his theory is the absence of "intermediate forms" in the geological record. His explanation is a rather weak claim that these cannot be found because the geological record is "imperfect to an extreme degree." How does modern science explain this point, which I'm sure is still brought up by creationists? -- Tothebarricades 04:48, 1 January 2006 (UTC)
The ignorant have been telling that lie for a century. Every time an intermediate fossil form is found, someone says, well where is the one intermediate to that! However far more important than the fossil record is the genetic record: every aspect of molecular biology has confirmed the fundamental applicability and usefulness of Darwinism as our best model for the obvious interrelateness of living things.

I am not going to argue the case one way or the other here. But here are some observations of mine concerning the question for the affirmative. Whether evolution is true or not is still based largely on personal convictions rather than solid evidence, from both sides of the camp.
TRANSITIONAL FOSSILS All the transitional fossils that I have read I stress 'READ' because I, like many others, only know what we have been told about amount to no better than the statement
"Pine cones have spirals that radiate in the same direction as snails".
Obviously this fact does not prove that snails evolved from pine trees. Yet, statements similar to this are used to proove that an animal that obviously belongs to a single species is actually a transition from one species to another. A transitional species should be an animal that obviously belongs to two different species and yet dosn't completely belong to either. Otherwise it is just proof that over time a particular species can adapt it's physical characteristics to suit it's particular environment. Black moth, white moth, they are all still moths with differnt adaptations, there is no proof of evolution from one species ino another different species there.
MAN EVOLVED FROM APE Scientists trace mans evolution from apes via cranial capcity and tool use. Yet I have read the question asked, If Austalopithicus were alive today, would we see it as a man or an ape? Answer: Ape. The fact that he used tools is evidence of his link to man. But don't chimpansees and apes alive today also use tools. Aren't there even members from other species not supposedly related to man that it has been said that they use tools. I have also read the question, If homo erectus were alive today, would we see it as a man or an ape? Answer: Man. His smaller cranial capacity is used to proove his relation to ape. So does that mean there is no variation in cranial capacity with people alive today?
DNA EVIDENCE The fact that various sequences of DNA are repeated almost unchanged from one species to another is cited as proof of evolution. However, the way I see it is that IF life was indeed created, then I would expect to see that the basic building blocks were reused over and over. This could also be seen as evidence of the handiwork of a single creator. Why change something that works. For example, If I were a car manufacturer, then why would I change the basic design of the wheel just because I now wanted to manufacture trucks, or planes or wheelbarrows.
All of the so called proofs of evolution that I have been 'TOLD' about are merely proof of the variation that can occur within a single species based on it's environment. This is called Adaptation. They are not proof that a species can evolve into a completely different species. This is called Evolution. In short Adaptation is not proof of Evolution.

Copernicus hardly said anything new (see Heliocentrism) Probably won't even figure in my top 100. deeptrivia ( talk) 23:01, 1 January 2006 (UTC)
And then there's Tycho Brahe. although he was mostly good at collecting top scientists around him. And Mendeleyev; the period table represents quite a jump in our understanding of the world. The argument against Copernicus also goes for Darwin, I believe, because he also largely just regurgitated things that had been though of before but no-one dared say out loud. But all this and the above all focus on fairly recent (and western) history. There were quite a few impressive scientists in old Arabia and India, although I can't think of any names from the top of my head.

(no question) To an atheist, religion serves the purpose of enforcing morality. Such morality is represented in the political stances of many people. Such morality rejects the legalization of any immoral activities. However in some circumstances, the war may have been lost already. In that instance a mitigating stance may be adopted. The moral decision picks the least of evils.
With such a perspective, a fellow may think that on most fronts that all moral people will be united. But some people have different definitions of morality. While strategy may require an otherwise moral person to refrain from a verbal attack on an immoral activity, in execution the immoral activity should be suppressed by that person to his/her greatest ability.
This strategic restraint can and will invite attack by under informed people. These people see the absence of endorsement, but not declaration of the immoral activity as acceptable as permission. (Explicit endorsement of an immoral activity encourages it and thus is immoral)
This strident attack, by people who do not accept strategy as a reason for ambivalence, is reflected in many areas of human interaction. Most organizations that operate from moral grounds, PETA, Greenpeace, etc, AND act aggressively upon their beliefs are marginalized by the majority of people who would prefer a more strategic approach. Anyone who does not agree with their strict beliefs are refused entry into their group.
A majority of people eat meat and yet a majority of people do not want animals killed in a sadistic manor. These states of opinion do irrecoverably clash because people desire efficient production of food, aka cheap food. The swiftest form of death is often thought to be the most desirable. Death by lethal injection may be therefore reserved for non-edible animals due to obvious safety concerns, and its inefficiency.
One important issue today is stem cell research. One of the methods harvests the immature human at a stage of non-specialization in the womb. For anyone who defines a human by his/her sophistication this is not a problem. This criterion has been used to justify excluding animals from being held as sacred life, and thus fodder for experiments and humans. Also people have been excluded via this criterion. As Darwin's theory makes clear the competition between the races leads to the exclusion of one to the success of the fitter race. To clarify, the better race will, via natural selection, be the last standing. The survival of a large group statistically accounts for random events.
The implications of natural's law should inform the thinking person. But sophistication and thus superiority as the basis of humanity is liable to the standard slippery slope argument.
The logic which defends natural law as moral hold that natural law is logical. Humans could not live together with free will if saddening things could not occur. Humans see part of morality as mitigating such sad events. The other part is avoidance of creating such events.
Returning to the stem cell research logic defines the basis of the decision to allow such an activity to occur legally as: 1. What is the boundary of human life? 2. What is the moral stance of the nation? 3. To what extent can this moral stance be applied to law?
Obviously protected and defensible life cannot exist before conception as the cells of reproduction have a transient lifetime before being discarded. After birth, by the laws of most civilizations, a babe is protected human life. At external viability, a babe merely needs to stay inside the mother to maximize the odds of survival. Between this and conception the picture is less than clear for the U.S. Supreme Court.
As moral people cannot accept an immoral activity, and will condemn even those who refrain from explicitly stating opposition to an immoral activity (who do have plausible reasons for the silence- such as lack of hard evidence) the Court's decision is immoral by someone's standard.
The U.S. as a whole finds any destruction of immature humans to be undesirable. Yet the degree to which it is abominable is debated. Some see the religious conservative's certainty that no uncertainty can be allowed in life or death moral decisions as mere dogma. Others see the lack of certainty prohibits government interference except for safety. Still another viewpoint observes that one's privacy should not be encroached upon, thus limiting government from informing any other person about a decision of this nature.
Obviously Americans allow uncertainty in the moral decisions of their leaders concerning law. Merely because in a plausible circumstance an activity would be inhumanly abominable does not mean that it must be prohibited. If some benefit is gained, even if such benefit is dubious, the potential benefit to future people justifies the risk of an immoral action.
However the U.S. government has allowed those people with no stomach for potential abomination to know that they do not contribute to this questionable activity. While not stopping a crime if it is in one's power to stop is immoral, holding oneself back when victory is not guaranteed is prudent and acceptable. Futility is an acceptable explanation for inaction. So the government does not fund the research except on cells already acquired. It is meaningless and immoral to allow a resource that exists to be squandered. However if the resource is immorally acquired one can "use the ivory while hunting the elephant hunter."
Also practically a police state will not be enacted by people worried about political morality. Such a state would expand the government beyond the desires of any American, and invite close regulation of business. While some people have no objections to the enlargement of government others fear even the local police.
An intolerance for questionable moral activity may appear to be mere grandstanding and hypocritical. Certainly the fact that religious organizations are not the primary source of aid for people who are having difficulties, especially financial difficulties, diminishes their ability for undisputable good works. Religion does not school thousands of children in morality. The social network that would allow people's mutual morality to reinforce each other does not cover without holes large areas. The control which church leaders have over their members is not as absolute as is necessary to judge the whole by parts.
Some atheists contend that religiosity is applicable only to private practice. Such people often have a low opinion of religious people. But to fairly judge religion's effect on society depends on an ability to separate it from the society. That is impossible. Therefore religiosity must be judged on its present pursuits.
The insistence on an incontrovertible policy on a moral issue is admirable even to atheists, who can and should respect the unwillingness to compromise principles and/or morality. When one judges atheist's perspectives their unwillingness to claim a heritage in history- due to the typically human mixture of events- one must do so on their present stances.
Morality is universal. To compromise it invites dissolution of all principles to the transient needs of the present.

Do you drink public water? The earliest sign of water commodification occurred over the last decade when the middle and upper classes stopped insisting that everyone have access to high quality drinking water, just as they abandoned the commitment that even children of poor parents have access to good education or crime-free neighborhoods. Both the water supply and the public schools in most large American cities have dropped below the level which upper middle class people consider acceptable. Those who can afford to drink bottled water and send their children to private schools do so, just as they pay for security in their own neighborhoods. Once you no longer rely on public drinking water, public schools, public libraries, and the police, it is easy to vote for politicians who promise to cut the taxes of the rich, as long as the streets, schools, and water are "safe enough" for other people's children.

Peritoneum is the abdominal space. Mesothelium is the membrane that lines it. In medical contexts the word peritoneum is used over a thousand times more often than mesothelium; in fact, peritoneal lining would be a clearer term to most doctors than mesothelium. alteripse 02:27, 2 January 2006 (UTC)
My understanding is that peritoneum is the serous membrane that lines the peritoneal cavity and consists of parietal and visceral subtypes depending on what it is attached to. Mesothelium, a part of peritoneum, is the single layer of flattened cells which overlies the areolar connective tissue base (which varies in thickness depending on its location and functional requirements). This is analogous to skin, for example, which has an epithelium covering the deeper connective tissue matrix of the dermis. Thats basically what my anatomy text says, anyhow. And it seems consistent with Stedmans definitions (see above). Mattopaedia 03:20, 2 January 2006 (UTC)

Short answer: Because it had a beginning and is finite (see Olber's paradox). deeptrivia ( talk) 04:27, 2 January 2006 (UTC)
To ask a more elaborate question:
Who was it again who is credited with coming up with this question? One answer would of course be that the assumption is wrong the universe is actually finite (as already stated). But another answer is that there is dark matter that obstructs much of the light. Wasn't there more? DirkvdM 15:20, 2 January 2006 (UTC)
If the universe is finite but unbounded, there must be geodesics which loop back around to where they started. So, there should be images of the Milky Way galaxy (or even larger structures that contain it) that appear to be very far away. If we saw one of these images with a telescope, would we recognize it? Is anyone specifically looking for them? It would be a pretty big breakthrough for cosmology if they were found, right? — Keenan Pepper 07:12, 2 January 2006 (UTC)

what is the cuase of dental decay?
Dietary sugars and starches increase the risk of tooth decay. The type of carbohydrate and the timing and frequency of ingestion are more important than the amount. Sticky foods are more harmful than nonsticky foods because they remain on the surface of the teeth. Frequent snacking increases the time that acids are in contact with the surface of the tooth. Yay that's all.-- Mac Davis ญƛ. 05:16, 3 January 2006 (UTC)
To return to the original poster's question, the only unequivocal facts about dental caries (tooth decay) is that three things must be present for it to occur:
That a tooth is necessary is self-evident. The other two factors have been demonstrated experimentally by using strains of germ-free rats, which do not experience dental caries until they are innoculated with cariogenic (decay-causing) bacteria and fed carbohydrate by mouth.
This does not begin to explain the wide variability of caries experience among individuals. There are more than a few cases where the bacterial load in a given mouth is off the charts due to poor oral hygiene and poor diet, yet tooth decay is absent. The converse is also true: excellent oral hygiene and attention to diet does not assure that tooth decay will not occur or even that it will not be rampant. This suggests that there are other factors that influence the incidence and severity of tooth decay-- whether it is some intrinsic quality in a particular person's tooth enamel, salivary antibodies, salivary enzymes, or some environmental element-- be it dietary or otherwise.-- Mark Bornfeld DDS 17:25, 3 January 2006 (UTC)
Is the concept of death star is feasible?
Statement #1
"Alderaan might have been a very tiny planet, so it would have been very easy to destroy". There is a fairly narrow range of planet types which can support human life. A human-habitable planet must have sufficient gravity to have retained an atmosphere after its formation, so Alderaan simply could not have been an extremely small planet. Furthermore, the Death Star has been explicitly described to be capable of destroying any inhabited planet.
OK, but Alderan may have been a small, ARTIFICALLY created planet. So it could have been build using superdense material material at the core to give it enhanced gravity.
Statement #2
So if we can't use melting energy or vaporization energy, how do we determine the energy requirement to destroy a planet? The answer, in one word, is gravity. If you wish to destroy a planet, you must scatter its mass so quickly that the forces of gravity cannot reverse the expansion process. In other words, you must accelerate the planet's entire mass to escape velocity. Another way of saying this is that you must bring the planet's gravitational potential energy state up to zero. The concepts of gravititational potential energy and escape velocity are both discussed in the science page. Using those concepts, the energy requirement for blasting a planet apart can be calculated.
The science page alludes to, but I cannot find where it says explicitly, that objects at the center have lower escape velocity than those at the surface. This is because the outer surface of the planet has gravity and tends to attract that at the center, away from the center. So it takes less energy to drive away the material at the center, than at the surface.
Depends, do you mean using current known physics, or unknown physics? Is FTL travel possible? What about time travel? I think that yes, a Death Star is feasible, but not with current technology, as with many other things.
If you really want to kill everyone on a planet, a Death Star is an overblown (sic) and hideously bombastic way of doing so. It's far easier, and altogether more useful, to do what the aliens do in the novel Footfall. You just take your moderate sized spaceship out to the asteroid belt, grab a nice sized asteroid, and drag it back toward your target planet, engines at full blast all the way in. Turn aside at the last minute (or, better, use a robot spaceship for the whole deal) and let the asteroid whack into the target planet. The poor inhabitants suffer a giant tsunami and an impact winter. You can come back in a decade or so and find a nice uninhabited planet, with the climate returning to normal and all the life-sustaining lower organisms intact, but all the people who defied you killed in way the average interstellar-villain type will find particularly gratifying. -- Finlay McWalter | Talk 20:01, 3 January 2006 (UTC)

How does this work? Is the winter average atmospheric pressure normally higher or lower than the summer (where I live I would guess lower because its raining all the time, but in places with cold clear winters wouldn't the pressure be higher?) How would a higher pressure cause the release of more methane than usual? If it's a lower pressure, am I correct in assuming that it has to do with the pressure relative to the vapour pressure?.

Why is it that no photos seem to exist of the stars from orbit or space? I'm not talking about telescopic observations, but rather shots of what the starry plane look like, from the perspective of the human eye, while in space. For example, when the International Space Station or other spacecraft are photographed, space behind them always appears simply black. Is this how it appears to the eye or is this simply a problem of camera lenses? Furthermore, one would assume that, for example, from the dark side of the moon one would have a really spectacular view of the stars, but I have never seen any photographs from this perspective from the Apollo program. What's going on? Does the presence of the sun in space hinder the viewing of stars and turn space into a black blanket? Do the stars only come alive when you are orbiting about the dark side of the earth or the moon? Why are they never photographed?

Greetings:
I'm trying to find material relating to the concept of "Universal ID", which, in my case, is defined using the following scenario:
" A group of government officials and information managers at major corporations who point out that the proliferation of single-use identifying keys for individuals is causing major inefficiency, embarrassing and costly cases of mistaken identity, and considerable waste of time and money. They propose a single lifetime ID for every Canadian resident that would be used for everything from tax returns to grocery check-cashing cards."
And I have to argue along the lines of:
"a universal ID would lead to loss of privacy and essential freedoms, and would be open to considerable abuse."
I would highly appreciate any pointers to wikipedia entries, books, journal articles, web site materials pertaining to "universal ID" in the above sense.

Is the prediction by astrology correct? Is the basis of astrology is firm?
Also note that the "theory" behind astrology, if it can be called that, is based on the actions of Greek and Roman gods. If you don't believe in Roman gods, like Mars/Ares, you shouldn't believe that people born when Mars is visible will have the traits of that god (combative, for example). There is a basic incompatibility in believing in Christianity or any other modern religion and also believing in astrology.

Are there any viruses, bacteria, etc., that live in the cold weather? I know that the cold weather just weakens the immune system and makes the body more succeptible to infection, but i was just wondering whether or not there are any viruses that actually just live in the cold environments and are strong enough to infect people. Thanks! ----- Eryn
Short answer: yes. Long answer is more complicated. There are bacteria and viruses that thrive in extreme environments: freezing and boiling hot environments, but these rarely affect (or infect) humans. Shall we assume that you are only interested in bacteria and viruses that can cause human disease and the degree of cold is the winter temperature range away from the poles where most of us live (like down to 10 degrees below water freezing)? Moderate freezing cold will kill many bacteria and some viruses, but the main effect of cold on bacteria is just to slow down reproduction and activity (which is why refrigeration retards bacterial growth). Bacteria and viruses vary greatly in their abilities to survive outside a host but the temperature is less of a factor in this than availability of water and food and absence of harmful substances like soap or high osmolality or intense sunlight. Dehydration will kill most bacteria faster than cold will, but some viruses can survive dehydration and some can survive indefinitely being frozen. Some pathogenic bacteria require direct person-to-person contact (e.g., bacteria of gonorrhea or the AIDS virus), but others (e.g., the spores of tetanus) can survive in the environment for long periods of time in various forms. For example, there has been concern about whether smallpox or influenza viruses can remain infectious in graves. The most recent example was the investigation a few years ago of 1919 flu victims buried in the permafrost of extreme northern arctic islands for 80 years. Precautions were taken to avoid releasing potentially infectious material. That said, I don't know of any cases of smallpox or plague or influenza known to have been contracted from graves or crypts. Cold weather does have an effect on transmissibility of respiratory viruses by affecting human behavior and perhaps altering mucous membrane defenses. Complex topic. alteripse 13:45, 6 January 2006 (UTC)
Thanks... I know this is a complicated question. You were very helpful. However, are there any specific instances in which entering a cold environment would promote the spread and possible contraction of a virus or bacteria into a human body? And if so, what are they???? ----- Eryn
Ah, this sounds simple, so I'll wade in. This site [27] explains the #1 myth, ie. if you go outside 'You'll catch your death of cold!', which is usually uttered by an old lady in a Jane Austen novel. -- Zeizmic 18:05, 6 January 2006 (UTC)
Thanks for your input. I think i worded my second question poorly though. Are there any bacteria, viruses, etc., that live only in the cold weather and are then contrsacted by humans or animals? For example, a virus taht lives and thrives outdoors in cool temperatures and then infects the first host that it encounters. possibly this bacteria/virus stayes dormant until contact with a host is made.... (Maybe this has been answered already in a previous reply and i just dont see it.) But if there is such a virus/bacteria, a name or description would be most helpful. Thanks! ----- Eryn
THANK YOU SO MUCH!!!! This last piece of information is exactly what i was looking for. Thank you so much for everything. -----Eryn
Hi, I read in several places that the fundamental building block of the universe is information or events...I know how it sounds, but I haven't read it in new agey looney pages, I read it in like, news articles, and in some physics pages which I cannot remember,but I can't distinguish real science from far fetched claims...so, do you think this is true or somewhat true? because I am aware that the building blocks of matter are quarks and subatomic particles like gluons and stuff.
also, quite apart from that, here's this quote :We are now synergetically forced to conclude that all phenomena are metaphysical; wherefore, as many have long suspected — like it or not — 'life is but a dream.' - Buckminster Fuller. see?

cool, so you mean that, information theory implies that nothing outside or besides the universe is required for the universe to exist? I mean, nothing besides the information and computations of our universe?... if so, how can it know that? I mean, can't the universe be like a big videogame? it can seem the only thing for us, but we can never know that which lies outside the computer that contains it ... maybe we can only know the software... it sounds really crazy and hard to understand, but i think that the information theory has space for a videogame conception of reality, or a simulation for that matter, but I know nothing about physicists, so I need the expert's opinion. -- Cosmic girl 19:30, 6 January 2006 (UTC)
I really suck at math and physics, but I believe that if everything is quantizied ( I'm sure I spelled that wrong :S )if everything is, I think the universe is no diferent than a videogame... but then, if it is, we can't know much about philosphy since the physics of the real universe (the one outside) aren't known to us...and maybe are even irrational to our brain...but that would surely signify there is a trickster God ...or a kid out there, haha -- Cosmic girl 16:52, 7 January 2006 (UTC)

There is a psychology database similar to Medline and I think it includes parapsychology research. It will be available through most college or university libraries. Ask a librarian for help. The best starting point is often a paper that you do have, because the librarian can see how it is catalogued in the database and can then help you look for older but similar papers. There are a couple of American universities that have supported "paranormal" research, usually in association with the psychology dept, often under the name of parapsychology. You could call one of those depts and ask a secretary if a faculty member would be willing to talk to you once for an "interview to help with a school science project" and you might get lucky enough to get a few minutes of time. If so, ask their opinion of the research in that area and ask for suggestions on how to most efficiently find published research on the topic. They may be able to suggest specific journals, search terms or even authors to look for. Good luck. alteripse 20:53, 6 January 2006 (UTC)

How close are mankind from inventing a source of perpetual energy?
Of course, there are many energy sources that will last for billions of years, so are as good as perpetual, like hydro, solar, tidal, wave, wind, and geothermal energy. And while each chunk of fuel for a nuclear reactor may only last a few years, there is enough nuclear fuel to power the world virtually forever. Renewable sources, like wood, are also good forever if properly managed. Only fossil fuels will be "used up" someday soon, perhaps decades or centuries, that's not certain. StuRat 20:40, 6 January 2006 (UTC)
It's a bit more abstract, but the questioner might like to read Conservation of energy which states that energy is never created or destroyed, but is a constant. However, the Second law of thermodynamics states that the energy of an isolated system, while constant, is in a constant process of equalling out, meaning that the contained energy becomes more and more difficult to obtain in a general sense. -- Quasipalm 20:52, 6 January 2006 (UTC)

Wow, you've really given this a lot of thought, I'm impressed. I still think the number of calculations necessary to search all of Google for all pictures of trees would take way too long to be practical for a search at present, but perhaps it would be good to have the technology ready and waiting for when such computing capacity comes along. Of course, just like voice recognition, I doubt if once you have the program optimized to find trees if it will be any good at finding, say, birds, until you alter the program significantly, then the same for every other object it needs to recognize.
I think some of the steps necessary for this to work might be valuable in and of themselves, however. I listed one above, another that interests me is "reverse pixelization". That is, I would like to be able to take a bitmap of a line and a circle, say, and create a vector representation of the geometric elements.

It greatly depends on exactly what the patterns are and is very uncertain, and it depends on whether the warming is greater in some areas or others.

Is there a limit to how many computers a router can handle? Should a standard 4-port router such as the Linksys BEFSR41 be enough to serve IP addresses to a network of 30 or more computers via various switches, hubs and wireless access points? If not, what kind of a router is needed? Thank you, Adam Konner 19:06, 7 January 2006 (UTC)

Here's why I wonder: When I asked the Comcast guy if the new service would be sufficient to support 30 computers, he said that would be fine, all I'd need is a router that can handle all those computers.

Searching for answers on the internet, I found this webpage that says, "On an eight-port wireless router, you may only use a total of eight connections, not eight wireless and eight wired."

There is a rumor going on on the internet that say that the PS3's GPU codenamed RSX developed by Sony and Nvidia is less powerful then Nvidia's upcoming GEFORCE 7800 GTX? Is this true? If it is true then that would mean that the PS3's graphics are going to be obselete compared to computers that would use the 7800GTX.
The "RSX" that the PS3 uses is basically a copy of the 7800GTX except the "RSX" may be a little faster. As with all consoles and the PS3 is no exception, every console is obsolete as soon as they are released because high end gaming computers catch up and eventually surpass console hardware technology in a couple of months.
I've read our articles on magnet and magnetism, which say that magnetic fields are caused by the motion of charges, but then add that electrons in atoms don't actually move. What electrons actually do in atoms, apparently, is (i) to sit around in orbitals and (ii) to possess a property called spin, but they neither orbit nor spin in the mechanical sense. How does this mysterious behaviour create a magnetic dipole? I'd like to add the answer to this question to our articles, even if it's just that "nobody knows". -- Heron 20:49, 7 January 2006 (UTC)
Thanks. I'll revisit the magnetism-related articles. There were some contradictory statements, about electrons moving/not moving, that I was unhappy with.

Are Jews (the people group, not the religion) smarter as a race? Because there seems to be alot of famous Jewish people, for exanple 22% percebt of Nobel Prize winners are Jews. So, do the Jews have a genetic or ethnic advantage in mental intellengence?
Cultural advancement of a group should not be mistaken for genetic superiority, it is like mistaking the superiority of a software for the hardware in the computer machine. Even if we all had similar computer hardware, since the software loaded in our machines will be different, it will make our computers look different. You may use different OS for example (OS is more like religious groups - I use Linux, but I am not a Jew). Race and skin color are more like the screen saver we use etc., etc. The main thing that really matters is the RAM and processor-speed; it can scientifically be proven that all humans have roughly the same levels. In the case of humans this all the more reinforced by the fact that a particular process of the brain can be trained to acheive high levels efficiency.

If nothing can reach the speed of light, why can light or electrons reach it?
is breaking the sound barrier as easy as snapping your fingers? if you snap your fingers, is the resulting sound due to breaking the sound barrier, the subsequent impact, or simply the loss of force due to friction?
if you google "sound geocities barrier snap" the very first page offered claims that a boom does occur on a very small scale.
Given that light can be pulled inwards by gravity(by something as massive as a black hole), and that it has a reliable velocity, and that those are the only two characteristics necessary for something to move into orbit around a celestial body, it there light endlessly orbiting black holes? Is there a distance out from a black hole at which, if you weren't pulled apart by the gravity or something like that, you would see a ring of light all around you? Because that would be pretty cool. It'd be fun to imagine something so absolutely black(except radiation) being encased by a sphere of pure light. If so, would that be near the event horizon? One problem I've found with this is that black holes are constantly expanding, so the orbital distance would be increasing as well, meaning any light currently in perfect orbit would eventually get pulled in, but maybe that's not a problem. -- Black Carrot 06:52, 8 January 2006 (UTC)

I understand that light hits the sail and is reflected back off the sail. My question is how masslesss photons can exert any pressure on the sail. When I use F = ma to calculate the force, even if the acceleration is from the speed of light in one direction to the speed of light in the reverse direction, I still get a force of zero for a massless particle. What am I missing ?
There is a device with a similar function, a "fan" inside an evacuated glass container with one side of each blade painted black and the other white. The difference in reflectivity causes the fan to rotate when in the light. This might be a purer example of the effect I'm asking about, since solar sails will also catch particles in the solar wind which do have mass. StuRat 08:03, 8 January 2006 (UTC)
I've read that article, and it really didn't explain it, just gave a formula to find the strength:
I'm really looking for an intuitive explanation. I suppose if it involves quantum mechanics or something else inherently non-intuitive, I will just have to accept it without understanding it. StuRat 09:09, 8 January 2006 (UTC)
Photoelectric effect. It's not really the same context as a solar sail, but it ends up ejecting electrons (which bear mass) - so it is ultimately the same principle. F=ma is an incomplete formula: it is incompatible with quantum mechanics. I myself am searching for a better formula (I have a hunch that one exists) that will account for the force a photon exerts on a mass, but also compatible with classical mechanical situations. (ie. breaking down the "mass" into different components). Elle vécut heureusement toujours dorénavant ( Be eudaimonic!) 10:02, 8 January 2006 (UTC)

The problem comes from thinking of rest mass as the real mass. The relativistic mass is the real mass in terms of actual behavior. But it varies according to the relative speed of the object so isn't as useful in terms of teaching students or of defining invariable qualities of particles, so rest mass gets called the real mass and the actual behavior of objects becomes more mysterious. But's its easier to teach and they aren't going to become physicists anyway... WAS 4.250 03:11, 14 January 2006 (UTC)

1) Bullets travel faster than sound, right? So why don't we experiance a sonic boom, something like two bangs one for the gunpowder and another shortly after for breaking the sound barrier?
2) Would there be a light barrier eg. in theory if an object of some sort exceeds the speed of light (although not possible) would there be some kind of explosion of light as it build up aroung the object, this is all merely theoretical.
3) Is 100% insulation of an object possible? eg. a means of an object forever retaining constant temperature? and on the other extreme is 100% heat conductivity possible?
4) What are quarks made of? And then what is that made of and then that, etc?
5) What effect does the combinations of quarks have on a particle eg. rather than 2 down and 1 up two bottom and a top, and if i had a rod of iron one made of the first type of neutrons and then another with the second kind would there be a visual, chemical or physical difference?

Continuing along the lines of 'miscellaneous question 3' and 'Thinking pc' above (I've put myself in that mindset, so now I interpret everything in those terms :) ). Quantum theory follows rationality to its logical conclusions. We are born with a priori knowledge, which we use to understand the word around us. All animals and other forms of intelligence have this. We have however formalised those rules (at least we try to). That's called mathematics. Next we started to strictly apply those rules and we came up with all sorts of things that our non-formal minds could no longer follow. You could say we have harnessed our intuition to the point that it's no longer intuitive to us. Then again, the notion of gravity was rather counterintuitive when Newton came up with it (something that excerts a force without touching!?), but we're completely used to it now. So maybe one day everyone will take quantummechanics for granted? Which is not to say we'll fully understand it. After all, do we really understand gravity? We merely accept its existence.

Is it possible to construct a device capable of sending someone to any one of the infinite alternate realities or universes? I also have a possible explanation as to the different variations and types of realities and universes: I believe that there are several different "Prime" universes. We live in the Earth Prime universe, or, the universe that all the different alternate realities are based off. All the litirature, stories, history, video game storylines, movies, and TV shows also have a Prime universe that that goes along with each individual series. History willl have several variations, like, George Washington doing a direct attack on the british instead of sneaking up on them during that fateful night. And your favorite characters from games and movies have their own Prime universes with their own infinite number of alternate realities. They all combine into one HUGE and always expanding omniverse. Anyway, you probably get my point. So, could it be possible to make such a device? (p.s. sorry about the long-winded theory. I tend to ramble on sometimes. I also got swept up by the concept and how exciting it would be if my theory proves true.) 68.116.175.201 23:57, 9 January 2006 (UTC)
If someone in this world were to be 100% emulated in a TV show, then there would be a copy. As I said earlier about the universes and variations, the TV show would have it's own universe, and have infinite variations. you could have a variation of our universe where YOU (yes, you, Black Carrot) could be of the opposite gender*. As for the discontinuities, there are things in tv shows that are unexplained,and that is where Fanfictions or destiny come in. if there is a unique fanfiction about a book or game, it causes the events of the fanfic to be a real event in that universes Prime. If there are multiple fanfics of the same event in different retellings, they mesh into one rettelling of the event and become true in the Prime of that universe, while variation realities select one of thoes fanfics to be real. if no fanfics are made to explain plotholes, a random explanation happens in the Prime of that universe. The discontinuity could be explained by a fanfic about a change in personality of the character, amnesia, or the characters decision to do something that, ultimately, leads to the lack of continuity. Also, two more things:

Well, I was trying not to make my posts so long, and thats why I didn't talk about that in my last post. You see, I often think about whether or not were in a fictional world that originated in some book somebody wrote or a lame TV show. For all we know, we could be in the worst sitcom ever made and not know it, But I have proof we're in the Prime Universe. Each variation is caused by the creation of literature that would describe how the world would be if something that happened had occured differently, or never occured at all. If we weren't the prime universe, then there would only be EXTREMELY small changes in between universes. The thing about Variation Universes(VU) is that if the universe is created by a story that tells only about a certain event, then that certain event is the one most important thing in that universes history, while everything else ends up being misinterpreted in general. The Prime Universe was started at random by I-dont-know-what and has no single event being the most important, and all the events that happen in this universe either get lost in the shadow of history or become warped, misread, misinterpreted, and mistranslated over time*. While VU's are created starting with that event, with no history as to what happened before the event took place. (*by this I mean like 200-1500 years) 68.116.175.201 23:57, 9 January 2006 (UTC)

Is interferon still active after freezing?
Interferon is a protein hormone. Freezing sometimes changes the tertiary protein structure, and can reduce ability to bind to receptors. The amount of change depends on lots of factors, but is hard to predict without actual experiments on the specific protein in question. It is unlikely to lose all potency with a single episode of freezer temperature or outdoor winter freezing, and does not become "toxic" or harmful, it just has a reduced potency. The degree of degradation (percent of remaining activity) is difficult to predict and might range from as little as 5% reduction of potency to 90%. Sorry, can't be more precise. alteripse 23:36, 9 January 2006 (UTC)
I am needing equations and basic information for angle of a flywheel and its varying pulling force which is created by rpms. What weight will the rpms allow the flywheel to pull when its speed increases and decreases? How much should the flywheel weigh? Will the flywheel be at 60, 45, or 30 degrees? This is for an at home project that i hope to take with me to class this fall 2006.
Thank you,

Note that it isn't the weight, but rather the moment of inertia of a flywheel which determines how much energy it has for a given rotational speed. A hoop shape will have a much greater moment of inertia than a disc of the same weight and radius. StuRat 00:56, 10 January 2006 (UTC)

When you burn any type of matter it goes through a process called pyrolysis which is essentially breaking down the matter at a molecular level through oxidation. What is fire? (a rapid oxidation process, which is a chemical reaction resulting in heat and light at varing intensities). So what actually happens when you burn a candle is, the flame of the burning wick melts and vaporizes the wax and you are actually burning the vapors from the wax .The wick simpily acts to increase the surface area to such an extent that even a very low rate of evaporation results in a sufficiently high local concentration of parafin molecules in the air to support combustion.
At this very moment, I find myself staring, bemused, at an h2g2 article, which describes the author's nipples, in two lucid sentences, as quadruple in number; symmetrical in arrangement, the lower pair being three inches below the upper pair; slightly uneven in size, the lower pair being smaller than the upper pair; and displaying all the characteristic attributes of the traditional human nipple, including sensation. Whether lactation is, or ever could have been, such a characteristic is not discussed. The remainder of the entry, comprising an additional three sentences, contains a description of the measures so far taken to allievate the author's confusion and despair, and an urgent plea for help which can not be lightly ignored by those possessed of even a modicum of compassion and human feeling. In the name of ben4nips, I call for a poll! An immediate and widespread display of generosity for this poor soul, whose only wish is to know whether he is alone in this world, or if there is another who shares his/her fate. If you or anyone you know, here or elsewhere, now or elsewhen, on Wikipedia or off, is or knows of someone who owns a perfect set of four or more nipples, respond! Hark to this call! A curious public awaits.

Does eating faster make you fatter???
A physiological reason is that incoming food stimulates release of incretins and other hormone signals that begin to signal satiety to the hypothalamus. If you eat fast, you put more food in before your brain decides you aren't so hungry anymore. alteripse 03:33, 10 January 2006 (UTC)
If you watched the UK Sky One Paul McKenna programme yesterday (which you may possibly have done to prompt this question) you'll notice he also discusses this. I've tried it, and eating slower does make you feel more full. Alteripse's explanation is perfect - you could describe there being a lag between you eating, and your stomach telling your brain you're feeling full. Eating more slowly allows time for you to feel full while still eating thus eating less instead of over-eating and then feeling bloated.

Anyway, electrolysis like this is perfectly possible and practical; people do it all the time. (It's a standard demo in high-school chemistry classes, for example.) You don't actually need high voltages, either. (The amount of hydrogen you get is proportional to the current, so you're better off with lower voltages and higher currents.) But, you won't solve the energy crisis this way, because the energy you get by burning the hydrogen you generate won't be any greater than the energy you spent splitting it off in the first place.

HI I'm doing a project on DNA at secondary school level (year 10) but first of all need to un derstand the basics, in terms of discovery, in a simple way. Who actually discovered DNA in terms of the helix model, because I always get a variety of names. Was it Rosalind Franklin, or James Watson and Francis Crick? I would be at this stage very grateful of any information received! Thanks.
A question for the thermodynamicists out there. I get the impression that it is probably useful to classify various energy sources as being "high grade" versus "low grade" or something in between, depending on how generally useful they are. For example, an energy source that manifests itself as heat with a temperature just a few degrees above ambient is "low grade"; you can use it to warm yourself up, but not much else. On the other hand, electricity is extremely "high grade"; you can do almost anything with it. (Mechanical energy, such as produced by a motor, is somewhere in between.)
Mixed up with my notion of "high grade" is an element of controllability; we seem to place a (to my mind) ridiculously high premium on the easy controllability of energy. For example, in a diesel-electric locomotive, diesel fuel is burned in a diesel engine to produce rotary motion... which turns a generator which generates electricity which is used to run motors to develop rotary motion again. This twice-around-the-barn conversion pathway comes at a pretty steep cost in efficiency, as opposed to having the diesel engines turn the wheels directly, but the compensating advantage is that the electric motors can be very finely and gradually controlled, whereas a pure-diesel locomotive would require some kind of high-power transmission, and those are notoriously difficult to build.
The tradeoffs can also be seen in home heating. If you heat your house with electricity, it's seemingly 100% efficient: any electricity which isn't converted by your electric heater into heat to heat your house with is lost as waste heat which... also heats your house. But of course it's not 100% efficient if you go back and look at the fuel that was (typically) burned in order to generate the electricity in the first place. If you had used the same amount of fuel to heat your house with directly (i.e. by burning it in your own furnace) it would certainly be much cheaper (and probably also more efficient). Heating your house with "high-grade" electric energy is overkill; heating is one of the few things you can usually get away with using the lowest grades of energy for.
Anyway, all of this is by way of prelude to my question, which is: what terms do real thermodynamicists use to talk about these notions which I've informally and unscientifically labeled "low grade", "high grade", and "controllable"?
Steve Summit ( talk) 18:13, 10 January 2006 (UTC)
I like the term Energy density (a rather undeveloped article). High-grade energy is the same as high-density energy. Low-grade or low-density energy requires a large amount of space, such as wind power, or trying to extract waste heat. -- 192.75.48.150 12:52, 11 January 2006 (UTC)

I realize that I have no scientific standing to ask a question about the article on the Gaia hypothesis, although I took graduate courses in geology in the early 80's, and in early 1979 took one of the good, early courses on "Ecoscience." I simply do not understand the language usage in one very specific case at the end of the article. It seems to me that the discpline of ecoscience of around 1980 had already developed a better and also accepted usage for one specific case which I describe below, in terms of a specific, just barely possible modification of one phrase at the bottom of the article on Gaia:
At the bottom of the article, there is an abbreviated section titled: "Gaia hypothesis in ecology." Here it is stated that "most ecologists agree to assimilate the biosphere to a super ecosystem...." Could this simply be a minor carelessness at the end of a very wonderful article? Let me voice my doubt by asking a question about the use of the phrase "super ecosystem." In what way does the expression "super ecosystem" differ in its meaning from the old "ecosphere" of around 1980? The "super ecosystem" as used describes the Earth at a planetary scale, such as is involved in the simpler description of "ecosphere."
Thank you for looking into this. -- Eorth57 21:25, 10 January 2006 (UTC)
So I'm a recent college graduate, I should be getting my Bachelor Science degree in Computer Science in a few weeks after my university finishes processing all my records and stuff.
One of the things I never, ever, ever got the chance to learn was writing compilers, or at least interpreters (it's probably easier to learn interpreters first before attempting to write a compiler for any given language, yes?). Sure, I did write a simple calculator program that allowed for parenthetical notation using a stack which gave me a very basic and simple idea of how parsers work, but that hardly was enough experience to dive in and attempt writing an interpreter.
Local bookstores aren't exactly filled to the brim with books on advanced topics like these in their Computing aisles, so browsing and leafing through the pages before I buy isn't necessarily an option for me. I notice there's many books on Amazon.com, but considering how freakishly expensive they all are, I'd rather not empty a paycheck on a ton of books about writing compilers or interpreters. Can someone with experience in this subject recommend one or two -definitive- books that cover most of what I need to know? I've read customer reviews on most of what I saw, and there seems to be serious pros and cons to all of these sources. A frequent complaint about "the dragon book" is that it doesn't cover object-oriented languages, but I'm not interested in that anyway. And some people say it's easy to understand, other people say it's convoluted and mazey in its explanations. And would buying a book on -compilers- be overkill if all I want to do is dabble in writing my own -interpreter- (I have, specificially, LISP or something LISP-ish in mind) from scratch?
Sorry if this question is worded in a rather roundabout manner. I just want to teach myself the general science and fundamental theories of writing interpreters and/or compilers so I have something that's actually substantial on my résumé, which is currently populated by tumbleweed, dust, and a couple of lazy cows, but I'm not about to spend well over $500 on a whole bunch of books on this subject, of which only one or two might actually be easy to comprehend. -- I am not good at running 21:57, 10 January 2006 (UTC)

Hello, and I hope you can shed some light on this. Closing the lid and walking away is supposed to be supported on my Dell Inspiron 5100 (Win XP).

I was reading somewhere recently that the long-distance communication common in sci-fi books/movies/etc. (i.e., communication between people/spacecraft at different planets, different stars, different galaxies) would be impossible because the limit to the speed of light means that communication between even Earth and Mars would have a minutes-long delay, and across stars would have a years-long delay. But isn't there something in quantum physics where making one particle spin one way makes another particle spin the other way at the exact same time, no matter how far away the particles are? Wouldn't it be possible to communicate via these spins (maybe one spin=0 and the other =1 and then read it via computer)? Zafiroblue05 20:23, 11 January 2006 (UTC)

What are the health risks and benefits of (dry) snuff? Mysteriousinventors 05:53, 12 January 2006 (UTC)
Cancer risk: Inconclusive. Studies have documented cancer in African users of snuff adulterated with charred aloe stems. Another report exists of a man contracting squamous cell carcinoma from placing snuff (presumably nasal snuff, as opposed to oral moist snuff, but this isn't specified) in his ear, an area that also receives UV radiation from the sun. Another report found a fourfold risk or oral cancer in persons using American dry snuff on the gums. There are currently no reports linking nasal cancer to European nasal snuff (with or without confounders like smoking, industrial chemical exposures, etc.), but this may be more a reflection on the paucity of studies examining nasal snuff than it may be on snuff's possible risks.

I suppose their is a benefit to me of other people using snuff. They will get cancer and die without ever giving me cancer, unlike with cigs. StuRat 06:37, 12 January 2006 (UTC)
It's not exactly a health benefit, but the miniscule byproducts of dry snuff (mainly from sneezing) are socially acceptable—unlike smoke and large amounts of sticky, foul-smelling saliva—so one can use it almost anywhere. My mother used to take it for its stimulant properties during afternoon classes in grad school, where smoking was prohibited, spittoons were not provided :-), and coffee had long ago worn off.

Hi. Let's say I have a row full of numbers (row A). Using the vlookup function I want to obtain the cell that a certain value can be found. So for example, if row A column 3 has the number 17, and I search for the number 17 using vlookup, I want the result to be R[A]C[3] (or whatever the syntax may be), so the result I am looking for is the cell itself, not the value contained in it. Is this possible to do? If so how? Thank you. - Akamad 07:04, 12 January 2006 (UTC)

If you can print it out in the exact same format as you had to start with, you can hold the two pages up, one on top of the other, to the light, and any differences should jump out at you. There is also a "diff" function on many computers that will find any differences in the two, automatically. However, again they must be in the same format for this to work.

Also note that Tesla wanted to broadcast power, as opposed to just a signal. It is possible to broadcast large amounts of power, but would be very dangerous and the ability of anyone to tap into the power for free would also make it impracticle. That said, if the power needs for a cellphone can be reduced to an extremely low level, they may not be so worried about the danger and costs, which would be greatly reduced to match.

Hello! If the human genome was 99% mapped to 99.99% accuracy back in 2000, why do we still have nothing remotely close to a cure for purely genetic diseases? As I see it, there is still no idea where most genetic diseases come from, let alone a cure. What was accomplished and announced with great fanfare back in 2000, if we have not seen any significant benefits 6 years later? I thought that having a complete understanding of DNA would enable us to totally eliminate thousands of diseases, from Down Syndrome to oily skin. What am I missing? Thanks. ironcito 22:24, 12 January 2006 (UTC)

Hello, I have a question about liquid soap that has been driving my family crazy! My liquid soap dispenser rests on my sink ledge in both of my bathrooms. However, in one of my bathrooms (the larger of the two) the soap becomes very watery, loosing almost all soap consistancy. It can still lather, yet its like pumping water out of the dispenser. We had some theory about people watering down our soap for some reason, but that is very unlikely. When we fill up the dispenser, the soap is always of regular thickness. After a few days is when it starts to go liquidy. I've recently put tin foil around the dispenser and the problem hasn't occured in a while. The soap brand is Dial. I'd appreciate any insight into this strange phenomenon of soap. M@$+@ Ju 23:18, 12 January 2006 (UTC)

my friends and i were having a discusion on wheather or not a United States milatary fighter jet has the structural intergrety and power (propulsion) to make it to outer space. Now we do understand that a fighter yet is not desinged for exiting the earth's atmosphere. let's pertend that we have to put that jet in space. what does it take. i believe a fighter jet does have the structural intergrety to make it and it does have the propulsion as welll. now i believe that because of the lack of oxygen in outer space, the yet would not make it. now i believe (i may be wrong) that if we attached some type of oxygen tanks to the jet so it can be used to burn the fuel, the jet then could make it to outer space. Main question is can the jet itself without any extra addings to the structure of the jet, can it make it then ( remember we are able to only add some type of gas tank to help burn the fuel). the other question is does the earth's atmophere cause the jet to burn on the way out to space.
I'm using a LiteOn DVD-writer; for the last year, it's been perfect.

Hello! I think I read somewhere that the 'Patella' or bones of the knee joint fuse and take proper form not at birth, but later on, as the human body develops. Is this true? I cannot seem to find this information anywhere at present. Thank you for taking time to answer this question.

The patella is cartilaginous in early infancy. The first appearance of bone occurs at 32 to 76 months in boys, and 20 to 40 months in girls. The bones of the knee change size and shape enough throughout childhood that an x-ray of the knee can be used to assess bone age. alteripse 23:48, 13 January 2006 (UTC)

The stars are big balls of gases (helium, I guess). Being so, why does it take billions of years to burn (fusion) all that gas, thus making a star extinct, in stead of burning it all at once, as when we light a fire next to a balloon full of inflamable gas, making it explode? Thanks for any help.-- 201.28.77.123 01:50, 14 January 2006 (UTC)
Gravity causes matter (mostly hydrogen) from space to gather together. Momentum causes stuff to circle each other rather than all go staight away into one big clump. Over time clumps get bigger due to gravity. Eventually some clumps of mater get big enough that the pressure at the center causes fusion. The fusion creates energy that counteracts the gravity. The size of the star is all about the balancing act between the force of gravity and the force of the energy created by the fusion. More matter in the star produced more gravity causing more fusion creating more energy thus balancing the more mass. When the balancing act is disrupted by something the star can colapse or explode.

In your website, you talked about scientific evidence for evolution.But then, how come I've heard Christians and creationists claim that there are scientific evidences against it? I'm confused! How can there both be evidence for evolution(or any other theory) and against it?
Exactly what are these claimed-to-be evidences against evolution and are they really evidences against it? Can you please make an article about these claims of scientific evidence against evolution?
One can find evidence for and against almost anything. For example the Flat Earth Society collected all kinds of peculiar and isolated "facts" they would claim as evidence against a round earth. Likewise if your a priori commitment is against evolution you can find some "evidence" against it. The latest fashionable evidence (now termed irreducible complexity) is a re-tread of William Paley's 19th century observation that the eye is really complicated and he just couldn't imagine any stepwise development of the eye; likewise Michael Behe just can't imagine that various complex molecular systems could have developed in steps. The other major "evidence" cited against evolution is that we don't have fossils of many intermediate forms of animal that would seem to have been in a lineage (we have many but not all). We have many articles on the controversy (see all the articles linked to evolution, creationism, and intelligent design). Despite these pieces of evidence, unless you have a prior faith commitment to the late 19th creationist scenario, the more you learn about biology the more it becomes overwhelmingly obvious that evolution in some form has certainly been occurring for millions of years, that all forms of life on this planet share a genetic ancestry, and that there a zillion pieces of evidence supporting it for every one that someone claims opposes it. alteripse 04:29, 14 January 2006 (UTC)

can homosexuals be treated through psychiatry???
Ask yourself if your heterosexuality can be "cured" thru psychiatry ... then you will know how homosexuals feel when they hear such a suggestion. StuRat 09:58, 14 January 2006 (UTC) i am a homosexual.that is why i am asking this question. Homosexuality is not considered a disorder, and most people would be offended by the suggestion. There are places where far-right religious groups attempt to do this, but it basically amounts to psychological torture. The Nazis spearheaded similar efforts. The result is usually the creation real psychological disorder (for obvious reasons) or at least personal trauma of some kind, not a change in the person's sexual orientation. -- Tothebarricades 11:53, 14 January 2006 (UTC)
The answers are certainly politically correct, but not entirely factually correct. There are people with homosexual orientation who have sought treatment to change it and there are doctors who have sought to help them. Treatments in recent decades in Western society have been voluntary not involuntary and have not involved anything that would commonly be considered "torture" (i.e., no involuntary unpleasantness to the body). The success rates for these treatments do not seem to be large and "relapse" (for lack of a better word) is reportedly common. The arguments above that (1) homosexuality is not a disease, (2) one should not attempt to change this orientation for oneself, and (3) that it would be unethical to attempt to help someone change his/her orientation reflect a reaction to historical social mistreatment of people with homosexual orientation, are political attitudes which should not be presented as "facts", and are in logical contradiction to the general social POV that humans shuould be able to own and develop their own sense of sexuality found throughout Wikipedia and educated western society. This is exactly what political correctness is: socially enforced maintenance of a single political viewpoint on an issue for which more general ethical principles would allow a different or more than one opinion. Those who feel compelled to rebut, please address what is said here rather than supplying me with opinions I do not hold. alteripse 14:42, 14 January 2006 (UTC)
As a person who does not discriminate by gender, I take great exception to Alteripse's implication that "homosexuality is not a disease" is a political stance. There is far more evidence that homosexuality is a natural phenomenon than a disease/disorder. To "wait for findings", as it were, would be like questioning the holocaust because you've never visited Germany. It has far reaching social, not political, consequences.

Can neurology ( meaning my brain's chemistry and structure) and my experiences, acount for all my feelings and thoughts? even my most abstract ones? I need to know this, because I am a psychology student torn between the phisicalist theories and the theories that say that my brain is some sort of radio reciever and my mind is something more ethereal or whatever... I particularly don't prefer one or the other...well I think I'd rather be just a mamal that can be explained by neurology, but the other theory doesn't bother me too much, what bothers me is not knowing which is true, so I was wondering if there has been any conclusive neurology breakthrough that settles this question.-- Cosmic girl 17:57, 14 January 2006 (UTC)

I was intrigued by the previous post, which brought about a certain old thought of mine.

How would it look if we were looking back? Let's say we were going at cx2 with our backs outward. Would it just look like rewinding a tape? is this possible?

But in the interests of trying to be helpful, you might try starting in safe mode to see if you encounter the same errors. If not it may be the result of some program running in the background while you are in normal mode. If I remember correctly, Windows 98 has a thing called MSConfig that allows you to remove items from your start up sequence without having to actually open regedit. I would suggest removing everything from start up and then seeing if your system is more stable. If you have to run Windows you should probably upgrade to Windows 2000 if not Windows XP. They aren't all that wonderful, but compared to Windows 98 they are more stable and reliable.-- ◀Puck talk▶ 20:19, 15 January 2006 (UTC)

Are there any proofs or signs about wheather we humans as a species have evolved over the period of the recorded history? around 6BC-present day.
Recorded history goes back a bit further than that-- maybe back to 2000-3000 BC depending on your criteria. I can think of at least some indirect evidence for at least one evolutionary change. I think there have been changes in the population frequency of genes conferring resistance to certain widespread diseases during that time. I suspect there are others but don't know any others off the top of my head. alteripse 21:24, 15 January 2006 (UTC)
I also have to disagree with Kainaw. There is no evidence that the genetic height potential of humans has changed in recorded history.

Many drugs such as atropine and digoxin are isolated from plants. Why are these drugs regulated by the FDA and St John's wort or saw palmetto are not?
If you were cultivating them for profit, they possibly might. I don't think it regulates wildlife. Also regulating the processing (ie. turning the plants into the drugs) is more enforcable than regulating the plants themselves. Elle vécut heureuse à jamais ( Be eudaimonic!) 23:58, 15 January 2006 (UTC)
The answer is straightforward and involves the legal difference between
drugs and
dietary supplements. A drug makes a claim of therapeutic efficacy and is subject to the requirements of the
FDA for proof of safety and efficacy. A dietary supplement is subject to (relatively) much lower standards of purity and truthful labeling, and cannot make claims of therapeutic efficacy. A manufacturer who wants to market a substance can decide which type of marketing is likely to be most profitable. This depends on many factors, such as the obtainability of
patent protection and the likelihood that a demonstration of therapeutic efficacy would increase the sales and allow a higher price. Typically the manufacturer will opt for dietary supplement status if the substance is not patentable (like a raw plant extract) or he has no confidence that efficacy will be demonstrable by affordable clinical trials. Digoxin is actually a molecule copied from the active ingredient in
foxglove but is not identical to the old
digitalis preparations. I think
atropine is the manufactured active ingredient of
belladonna, but the pharmaceutical product has not been extracted from plants for many decades. I think there was a
chemotherapy agent (
taxol) that was actually extracted from plants a decade or so ago, but that is becoming less and less common.
Note the definitions have nothing to do with "natural" versus synthetic, or purified from plants versus invented, as there are plenty of examples of prescription drugs obtained from living sources and plenty of examples of dietary supplements that are synthesized in factories (e.g., most vitamins). A couple of excellent examples that show that the distinction has nothing to do with the biological nature or properties of the substances are the pairs of melatonin and pitressin, and dehydroepiandrosterone and hydrocortisone. The first pair are small protein hormones, secreted by the pineal gland and posterior pituitary gland respectively. The second pair are steroid hormones produced by the adrenal glands. All four have therapeutic uses. The first item of each pair is classified and marketed as a dietary supplement while the second of each pair is a drug.
Obviously many manufacturers market their dietary supplements with hype that skates as close to the edge of the law as possible, implying that their product will fix whatever ails you while including a little message that "this product is not intended for the treatment of any disease". alteripse 00:48, 16 January 2006 (UTC)
Hi wikiguys. I thought this was going to be a question-posting page but it's headed "comment". It's a question!
I've read both the "Y chromosome" article and the "genetic genealogy" article, and they didn't answer the question I was pondering about. I know we males get our Y from our dads and pass it to our sons (with a little bit of crossing-over at the tip during meiosis?), and I gather there are some variations in the Y but it mutates slowly enough so that, eg, one should be able to identify all of Tom Jefferson's male descendants (or perhaps they could be descendants of his brothers or cousins?). But *how* slowly does it mutate (on average of course)? How big a group of us would there most likely be with exactly the same set of base-pairs on the Y as I have - back to the great-to-the-nth-grandfather and out to the nth cousins, where n is what (or in what range)?
I'd quite like a personal answer to this, but the main reason I'm asking is so a bit more detail could be put into the exising entries. I find them interesting but provokingly vague at the moment.

This is an area of much research and some controversy. Many of the commercial genetic genealogy sites such as this one [68] assume a typical mutation rate estimate for each marker gene Y chromosome of about 1 in 500 generations (or 0.2%. On the other hand, cutting edge research on microsatellite mutation rates is producing different answers. See [69] for a more complicated and current discussion of the variation rates. These authors describe nearly a 10-fold difference in the rates produced by different estimates, suggesting that the results from some of the commercial public market labs are using some estimates that may need to be revised. alteripse 02:29, 16 January 2006 (UTC)
Thanks guys - all I wanted to know and possibly more. [Alteripse, do you spend all your time answering queries on this page?] I was really interested in an answer at an order-of-magnitude level, so regardless of doubts about whether the answer is 100 or 500 generations, it's clearly more than 10 or 20 (so if every male sharing the same Y had the same surname, there'd be less surnames than there are, cos surnames only go back 15-20 generations I guess). And Nunh-huh, yes, the query was inspired by watching a doco on Jefferson and Sally Hemings. I gather that some of Hemings's descendants who thought they were Jeffersons had their suspicion confirmed (as much as it can be - they could be descended from TJ's 3rd cousin if he was lurking around Montecello), while others found out they were clearly not descended from him?

Would a digital SLR camera, with a bigger diameter lens than, say, my little cannon elph digital camera be able to take better indoor pictures without a flash? In other words, if I try and take pictures inside without a flash (even in a well lit room) they are either blurry (too long an exposure) or very grainy (larger "ISO"). My question is, would a bigger lens be able to gather more light in a briefer amount of time, and therefore allow me to be able to decrease the length of the exposure without having to resort to higher ISO's, or is the aperture set somewhere else and this has nothing to do with the diameter of the lens?

Can an individual who is allergic to Penicillin have an allergic reaction if they eat Gorgonzola or Blue Cheese? Thanks.
I think the point of the question is that (since penicillin was discovered because it was produced by a mold) whether the blue mold that is included in the cheeses might contain enough natural penicillin to activate an allergy. The answer is no. I hate to say that there has never been a reported case (always a hazardous claim, even though the case may not have accurately proven cause and effect) but I am certain that if cross-reaction to mold were a clearly demonstrated phenomenon, it would be included in the avoidance instructions allergists give when someone is allergic to penicillin. Penicillin allergy is relatively common and certain other rare cross-reactions are well known to most doctors. alteripse 13:21, 16 January 2006 (UTC)

I would assume it would be easier because adults are stronger and would be more likely able to generate the force needed to propel the bicycle to a stable speed. But that could vary for someone very out of shape. Now adults are generally more easily embarrassed and therefore less likely to accept help and maybe less persistent in trying again, so maybe it would take longer in the end.

The current risk is important, but so is the potential risk. If we only took preventative actions against things which have already killed millions of people, we would suffer from massive deaths every year from disease. Some apparent threats, like Mad Cow Disease, never materialized, probably due to the corrective actions we took, like stopping the practice of killing sick cows, grinding them up, and feeding them to healthy cows (in their grain). Other diseases which were not widespread at the time of the first warnings, like AIDS in the early 1980's, have grown to the point where they do kill millions every year. So, such warnings are not silly, but should be taken seriously. StuRat 15:48, 17 January 2006 (UTC)

I have a suspicion he does not have a nearby Barnes & Noble.

The "institutional price" for one of these can exceed a thousand dollars a year. He will need to contact the publishers directly for the journals he is interested in; the contact information is usually available at the publishers' websites. An alternative is that many American libraries are willing to ship duplicate journals to third world libraries, but you don't always get the latest issue when published.

There are two species in the chimpanzee genus, the Common Chimpanzee, Pan troglodytes, and the Bonobo or Pygmy Chimpanzee, Pan paniscus. Wikipedia's articles do a good job of explaining the difference. (Note: there is no "chimpanzee family": chimps are in the same family as humans, Hominidae.) Gdr 19:44, 17 January 2006 (UTC)

Do you have an estimation for "Total number of cell divisions in the history of life?" Thanks
Taking inspiration from the
Drake Equation, I have created the "
Johntex equation" in attempt to estimate how many cell divisions have occured since the origin of life on
Earth:
Variable | Description | Value | Source |
---|---|---|---|
EarthPop | Current world human population | 6,450,000,000 | http://en.wikipedia.org/wiki/World_population |
HBC | Cells in an average human body | 1E+14 | http://ask.yahoo.com/20020625.html |
HBCD | Number of cell divisions needed to make 1 x 10^14 cells | 7.03687E+13 | Math |
HBCR | Numer of times, on average, each cell in the human body replaced during life | 3 | My estimate |
PerBio | Percent humans comprise of the world's biomass | 1% | http://www.space.com/scienceastronomy/plant_food_040629.html |
Years | Years since the origin of life | 4E+12 | http://en.wikipedia.org/wiki/Timeline_of_life |
Turnover | Number of years needed for world's biomass to turn-over, on average | 20 | My estimate |
Conclusion | Total number of cell divisions= | 2.72E+47 | =EarthPop * HBC * HBCD * HBCR * PerBio * Years / Turnover |
The total of 2.72E+47 would be just for life on Earth.
If one wanted to also consider the number of cell divisions that have occured in extraterrestrial life, one could multiply by the number of worlds that support life using a modified version of the Drake Equation. To do this, one would ommitt the variables relating to the life forms developing an intelligent culture, for example:
If R=10, fp=0.5, ne=2, fl=1, and L=100,000,000, then the modified Drake equation would give 1E+09.
Multiplying 2.72E+47 by 1E+09, we get 2.72E+56 for the total number of cell divisions of all life anywhere in the Milky Way. By comparison, the total number of stars in the Milky Way is estimated to be something more than 2E+9. By these calculations, the number of cell divisions that have occured in the galaxy would be about 1.36E+47 times more than the number of stars in the galaxy.
I think these figures are probably accurate to within about 10 orders of magnitude. Johntex\ talk 22:25, 18 January 2006 (UTC)
That equation doesn't look quite right to me. For example, why would you multiply by 1% if you thought humans were 1% of the biomass on Earth ? You should multiply by 100 instead. Of course, this is still assuming humans' cellular reproduction rate is the same as the average of all life, which is a highly questionable assumption.
I would also think you would do best to ignore humans and concentrate on life forms which have been alive for much longer than us and which have cells that reproduce much faster than us, such as bacteria. They will account for far more of the cell divisions in the history of the world than humans will. StuRat 22:41, 19 January 2006 (UTC)

This isn't just limited to the wheels of a car - you can also see it in LPs, for instance. I believe it's due to an interference effect, which occurs because your eyes only have a limited "refresh rate" (ie they only pick up new information at a certain rate, approximately ten times a second IIRC). If the wheel has repeating radial markings (eg spokes), if it spins at a certain speed, your eyes think that each spoke has moved slightly backwards when in fact it's the previous spoke which has not quite reached the position of the next one in the time it takes your eyes to take in new information. So your eyes are telling you that the spokes are actually moving slowly backwards... — QuantumEleven | (talk) 14:26, 19 January 2006 (UTC)

In Britain everything uses 13-amp plugs except for electric shavers which for some reason use two pin plugs. Why is this, and why is it only for electric shavers? smurrayinch ester( User), ( Talk) 15:10, 19 January 2006 (UTC)
I think your missing the point, i thinks its more to do with having a different plug in the bathroom so you don't get tempted to put your plasma screen in there.
Our article BS 1363 gives some description and this article says that the standard BS 1363 is to be installed throughout (no bathroom exception). A point of confusion may be interchanging the words outlet (on the wall) and plug (on the device). The outlet requires that a third prong on the plug (device) be present and inserted into the outlet in order for the other two plug prongs to be allowed "in". Since double insulated devices (electric shavers, hair dryers, etc) don't really need this third "earth/ground" connection for safety, those devices may use a non-conducting (plastic) prong in order to open the outlet for the other two prongs on the device to be allowed in. Back to the original question, device manufacturers have devised some proprietary workarounds that permit their double insulated devices to be inserted while having only two prongs and I suspect that is what Smurrayinchester was referring to. hydnjo talk 19:47, 19 January 2006 (UTC)

great, I agree, but for example, what do you think about David Deutsch? I don't know if I missunderstood the article, but How can an infinite computation (software and information) be possible without a computer (hardware)to contain it? here is one quote of his: Think of all our knowledge-generating processes, our whole culture and civilization, and all the thought processes in the minds of every individual, and indeed the entire evolving biosphere as well, as being a gigantic computation. The whole thing is executing a self-motivated, self-generating computer program. More specifically it is, as I have mentioned, a virtual-reality program in the process of rendering, with ever-increasing accuracy, the whole of existence. I don't understand what he means since he is an atheist and that sounds a lot like abstract and uncomprehensible mysticism and absolutism to me. other way to put it would be the way he said it, but stressing that there's a reality outside that whole of existence he talks about, because that whole of existence mus be being computed somewhere otherwise it would be just God. I mean, how can a virtual reality be self generating? i think it can only be so from a 'pantheist' view...but not from a virtual reality view, since that requires an outside world I think.-- Cosmic girl 20:41, 19 January 2006 (UTC)

I was merely entertaining the thought that it would be rather cost effective to send a self-replicating robot with the ability to follow simple instructions and build structures as well as copies of itself to the polar caps of the moon using the materials it mines from beneath the surface. It also would probably be cost effective if they could build solar-panels but I have a feeling that you can't build that kind of stuff from raw materials on the moon! freshgavin TALK 04:39, 20 January 2006 (UTC)
I suppose a self-replicating robot is available today...provided it is supplied with two halfs of a robot and merely needs to plug the halfs togther.

A robot that could assemble another starting from mining the raw materials, smelting them, etc., might not be available for centuries. StuRat 05:55, 20 January 2006 (UTC)
If you have time, try reading Prey by Michael Crichton. In that, nanobots are created that can kill things, break them down, and turn them into swarms of nanobots that can continue the cycle.

The tooth enamel page states that tooth enamel is hydroxylapatite. The Hydroxylapatite article discusses how hydroxylapatite is sometimes used as a bone filling in some medical procedures. This begs the question (for me, anyway): Why isn't hydroxylapatite used as a dental filling? (I previously asked this question on the talk pages of dental filling and hydroxylapatite. Both articles would benefit from a mention of the answer, if anyone knows.) Regards - Tempshill 06:39, 20 January 2006 (UTC)
Actually, tooth enamel is predominantly composed of hydroxyapatite, with a minor amount of organic component. The reason it is not used as a restorative dental material is that it cannot be cast, pressed, or otherwise shaped into solid forms that can accurately fit the cavity of a tooth. It also cannot be placed and adapted into a cavity in a plastic state (as can, for example, dental amalgam).
It is unfortunate that hydroxyapatite cannot, at least with current technology, be used as a dental restorative material. Fillings made of this material would have many physical properties (strength, hardness, and coefficient of thermal expansion) that would make it ideal.
Hydroxyapatite (Calcitite) and other mineral bone analogues are used in bone grafting applications, but not primarily for their physical properties. It is more for their relatively high biocompatibility, and their ability to form a physical scaffold on which new bone can form and fill in. Unfortunately, there is no analogous process that occurs in teeth. When enamel is injured, it must be repaired with artificial materials-- it does not heal, as does bone.-- Mark Bornfeld DDS 19:12, 20 January 2006 (UTC)

Blue Platypus was trying to reason it out but was working with several wrong assumptions about volume of diffusion and buffering capacity of blood and body tissues. There are iv solutions designed to mitigate (or not exacerbate) acidosis (such as lactated Ringer's solution), but there are very few clinical situations where you could detect an advantage. Also note that there is a lot of quackery out there about how the body handles acids and acidic foods that is pure nonsense. alteripse 18:19, 22 January 2006 (UTC)

I enjoy dissembling certain types of electronics, both just to see what the insides look like, and to try to learn more about how they work. I notice that on many devices it says something to the effect of "danger risk of electric shock if opened". I haven't been electrocuted by any of them yet, but I'm wondering if there is really any danger. If there is, how can I tell which parts(including wires) are safe to touch/disconnect and which ones aren't? Flea110 22:58, 21 January 2006 (UTC)

I am a sophmore in college. I can't remember when the last time was that I concentrated on school work, while completely sober, for more than two hours at once. Most of my major papers and tests are handled with the aid of amphetamines (which I only use approximately once a month). However, I can concentrate on things that I am enjoying for extended periods of time. For example, I did exceptionally well in high school debate and I can read a good book for a few hours. Is there a chance that I have ADD? What can I do that might help me to concentrate on school work? Thanks for the help!

I am going to give some counter-arguments refuting the arguments many people have made against the theory of Parallel Universes:
First, I've heard that the theory of Parallel Universes isn't very scientific.But just because a particular belief,idea or guess isn't scientific doesn't mean it's not true, or it can't be true.Look at all those religions and religious beliefs in the world.Those beliefs which many of the religions in the world are based on or teach aren't very scientific, but that doesn't mean that they're not true!! I've heard some creationists say that the theory of Parallel Universes can not explain why the Universe has the conditions,physical laws and physical constants needed for life to exist, because there's no evidence to prove it.Actually, things are the other way round.The fact is, there is evidence to prove it is true because it explains very well why the Universes has the fine-tune conditions needed for life exist.After all, people have also said the theory of intelligent design is not true because of that sort of stuff.
Second, I've that the Multiverse hypothesis is not true because some scientists say that it's inevitable that the Universe turned out the way it is.Are they saying they know the reason why the Universe is the way it is, with all those physical laws,rules,principles and constants?First, isn't that pretty arrogant?Second, what is reason they know that the Universe is the way it is?If they don't know why the Universe has the laws and physical constants that it has, then they shouldn't make such an arrogant claim!!
Third, I've heard that the exist of many universes raises the question of whether virtual worlds generated by conputers and virtual reality should be counted among them.The existence of other universes means the existence of places and areas of space that you cannot reach no matter how far travel across the Universes.So the virtual worlds contains virtual objects, and are generated by computer or VR, are virtual or 'imaginary' Parallel Universes.
Fourth, I've heard that the Multiverse hypothesis violates Occam's Razor.By making such a theory, you then have to explain why different universes have different physical laws and constants.First, the Multiverse hypothesis is the simplest explanation!Intelligent design is far more complicated.Second, many theories have parts of them which unexplained when they were first made.For example, Newton's theory of gravity didn't explain why gravity exists.And even when the general theory of relativity explained it as a distortion of space time, that didn't explain why matter distorts spacetime.And when Darwin's theory of evoltuion was made, it at first didn't explain why different animals have differentlevels of survival ability in the first place or how living things originated in the first place.Third, as to what other universes might be like, that's very interesting.Who knows?One of them might even be like the world of Narnia in the story, the Chronicles of Narnia. Please tell the people who have been arguing against the multiverse hypothesis about my refutations or counter-arguments!!!!

I'm not looking for medical advice here, just someone to blame. (It'll probably end up being me.) What can cause an amalgam filling to crack? I'd love to think it was my dentist doing a sh*tty job, but one can only be so hopeful. Cernen Xanthine Katrena 08:07, 22 January 2006 (UTC)
Fillings crack for the same reason other things crack: the forces to which they are exposed exceed their compressive or tensile strength. This could indeed be partially the dentist's fault, if he selects a filling material that is inappropriate to the situation. For example, the use of dental amalgam in a setting where a full crown is more suitable might be considered unrealistically optimistic. However, this type of treatment compromise is made all the time, for the sake of economy. And as often is the case, a short-term economy eventually leads to extra expense if the selected material is not sufficiently durable.
Fillings also crack when they either become weakened or are subjected to abnormally high forces. For example:
So, either the patient, the doctor, or plain dumb luck may be responsible for structural failure of a filling.-- Mark Bornfeld DDS 15:01, 22 January 2006 (UTC)

I have the OEM version of Windows XP Pro installed on my current computer which I built myself. But I've just bought some new kit to build a replacement computer (new case, CPU, motherboard , VGA card and SATA hard-drives), because my current set-up is a bit tired. I plan to migrate everything from the old computer to the new one and re-use my existing version of Windows, but during the time of migration I expect that both computers will be in use until I retire the old set-up. I know there's a 45 day period where you don't have to activate Windows, but am I right in saying that I need to activate it in order to download the hotfixes etc? If I try to activate Windows on the new computer will it work or will it fail or will my old computer stop working because it think that I've got a pirated version? MrMcarthy

|<--F1-- | |<--F2-- | |
I have a question about the relationship between the linear and rotational analogs of
classical mechanics. In space, if a force (F1) is imparted on the end of a rod, the rod would gain both
translational kinetic energy and
rotational kinetic energy, and the force would be accounted for as both a translational force and a
torque. However, if an equal force (F2), is imparted on the
center of mass, there would only be a change in linear KE since there would be no torque. However, these two results seem to contradict each other, and to violate the
conservation of energy: despite the same force, the example of F1 gains additional (rotational) KE. Thus, the first time I saw the problem, I thought F1 should be divided into two components, one to calculate linear force, linear momentum, and linear KE; and the other to calculate torque, rotational momentum, and rotational KE. Yet I know this is not true from what I have learned(correction: see my comments below). How can one rationalize the extra energy due to the "double-accounting" of force in the example of F1? Does the force act over a greater distance? Or is there more energy lost to heat? --
JianLi 17:04, 22 January 2006 (UTC)
Assuming the object is in space, it would only rotate about it's center of mass if pushed on the end as in the case of F1. Thus, it would only have a torque in that case. StuRat 21:22, 22 January 2006 (UTC)
No, its center of mass will also have an acceleration equal to F1/m. So it will translate also. deeptrivia ( talk) 21:26, 22 January 2006 (UTC)
This is a tricky question. First of all, a force on the end of a ruler in the absence of friction will certainly result in both rotation and linear motion. The linear motion should be the same regardless of where on the object it's applied, so there does appear to be a paradox. I'm going to consult with some of my fellow physics grad students and get back to you on this later. -- SCZenz 00:59, 23 January 2006 (UTC)

Hi, this is the original poster. Thanks to everybody (especially Keenan Pepper, deeptrivia, and StuRat) for responding. I haven't read all your responses yet. However, I see some pretty heated arguments, and I just wanted to clarify what I know for sure (as these answers are from the 1998 Advanced Placement Physics C Test (mechanics section, second free-response)
The reason there is so much debate over this, I think, is that it's hard to imagine what it is like in space since we draw heavily upon our experience on earth, where friction and gravity are big factors. That's why the ruler example that StuRat cited is not an accurate simulation of F1. Instead, try dropping a pen above a desk, and, as it is falling, hitting its end with with your finger in a motion parallel to the plane of the table. That way, friction would not be a factor, and also, gravity would be acting perpendicular to the force you impart, so it wouldn't affect it. As you can see, it gains both translational motion and rotation. -- JianLi 03:34, 24 January 2006 (UTC)

FYI, I looked at the original AP question, and it does not mention force at all, as it is a conservation of momentum problem involving collisions and velocity, so what I said in my original post, about what was "true," is not necessarily right (the amended diagram is above). That said, the previous two points that I numbered and bolded still apply. In this case, both collisions gain equal linear momentum/KE, and the upper case also gains an angular momentum/KE The AP problem is: there is a massless rod of length "l" with spheres of clay on the ends (each with mass "m") kinda like a barbell. Another sphere of clay with mass "m" and velocity "v" hits the construction perpendicularly and sticks. In the first example, it hits it in its center of mass, and the second example it hits at its end (striking one of the other spheres). Remember, in both examples the moving mass sticks to the barbell. Obviously, the two systems have the same initial KE. However the rod in the second example gains rotational KE as well as the translational KE that the first rod also gains. Why? This is because in both cases, KE was lost to heat, etc. due to it being an inelastic collision (since the clay stuck), and more KE was lost in the first collision than in the second, which explains why the first collision had enough energy to have rotational KE too. Like I said, I'm not sure how this relates to Force, as this problem only mentions velocity, and I think it could be any quantity of force, depending on how much time the collision took () -- JianLi 04:12, 24 January 2006 (UTC)
Ok, with the new clay ball model there would be some changes. In addition to delivering a certain amount of energy, as the force would, the clay balls will also increase the mass. In the case where the clay ball hits at the other clay ball on the end, the rod will rotate about the NEW center of gravity, taking the new ball's mass into account. Since it doesn't hit exactly at the end, but rather at 1/2 the end ball's diameter from the end, some linear motion will also be imparted. StuRat 19:39, 24 January 2006 (UTC)

Can the resolution of the human eye be (roughly) described in megapixels the way digital camera resolution is expressed?
Digital cameras (and conventional ones too) mimic the retina using color sensitive receptors for red, green (x2), or blue on a CCD, which is much bigger than the retina. Each receptor functions as both a rod (since each one captures luminosity, regardless of color) and cones (specific to its named color only) at the same time. The receptors send this information to a CPU, which either compresses the info (like JPG) and saves it or just saves it (like RAW). A 3.1 mega pixel camera has 3.1 million red, green (x2), or blue receptors.
My biology text book says, “Input from about 125 million rods and cones synapses on bipolar cells, which send the signals to just one million ganglion cells.” Does that mean that the retina (our body's CCD) has a resolution of 125 mega pixels which is then compressed to a 1 mega pixel image sent through the ganglion cells?
For a digital camera to capture an image as crisp as the human eye can capture, would it need to be 125 mega pixels per retina sized area of its CCD?
Of course, we would need a matching printer, right? What if we were using our fictitious camera as a bionic eye and plugging it directly into the optic nerve? Would we only need one mega pixel per retina sized area on our CCD or would we need the 125 mega pixel with a CPU to compress the info down to 1 mega pixel? -- TheLimbicOne( talk) 18:24, 22 January 2006 (UTC)

Note that just about any theory has evidence for and against it, you must go with the majority of evidence to determine if the theory is reasonable or not. For example, the presence of pyramids in both Egypt and South America could be taken as "evidence" that the ancient Egyptians colonized the Americas. However, there is far more evidence that they didn't (different style pyramids, different time frames, low technology level of Egyptian sailing vessels, different genetic profiles of the individuals, different skeletal features, lack of historical accounts, etc.). StuRat 23:18, 22 January 2006 (UTC)
No scientific theory is perfect; every nontrivial scientific theory has unexplained aspects and unanswered questions. Science is always trying to refine its theories and answer new questions that come up. If there are currently a few unanswered questions or unrebutted critiques of evolution, this does not mean that evolution is "troubled" or "in doubt" as a theory. Quite the contrary: it means it's a healthy, vibrant theory. (It would be extremely unusual if a theory as complex as evolution did not have a few unanswered questions or unrebutted critiques at any given point in time.)
What's important to realize is that most of the allegedly "controversial" aspects of evolution which are bandied about like so many brickbats by evolution's latter-day critics are not, in fact, brand-new hitherto-unasked impossibly hard questions which scientists can't answer. They are or might once have been good questions, but they're questions which were asked and answered decades or centuries ago. Our current understanding of evolutionary theory does not quail before these questions: it embraces them; it's happy to answer them; it owes its current form to the fact that it has successfully addressed and answered them.
In particular, the notion that life is "too complex" to have arisen by chance, and "must obviously" be the work of an intelligent designer, is a very, very old one. It was most famously expressed by William Paley over two hundred years ago, in 1802, but it goes back at least to Cicero in ancient Rome. If you accost a modern evolutionary biologist and suggest that life is "too complex" to have arisen by chance, he is not going to slap his forehead and say "You're right! I never thought of that! Our whole theory must be wrong!". Instead, he will explain (if you're patient and open-minded enough to listen) how the available genetic diversity and mutation rates and natural selection mechanisms are more than adequate to explain the current complexity of life as we know it, given the millions of years it's had to evolve. It's true that this is a surprising result, and that it contradicts intuition. Many scientific results are like that. But the evidence behind the theory and the math that ties it together are unshakable. Steve Summit ( talk) 03:57, 23 January 2006 (UTC)

If you add up all of the energy in the universe, converting all mass into energy, and then allow for the negative energy of gravitation, the result is zero!
"In the inflationary theory, matter, antimatter, and photons were produced by the energy of the false vacuum, which was released following the phase transition. All of these particles consist of positive energy. This energy, however, is exactly balanced by the negative gravitational energy of everything pulling on everything else. In other words, the total energy of the universe is zero!" [86]

So they go find some free, "public domain" content (or what they imagine to be public domain content) and copy it to their fledgling site. Usually, in an attempt to make their site seem attractive (and assuage whatever lingering internal pangs of guilt they might have) they will claim that their site somehow presents the copied information better, or otherwise adds value for their site's readers.

Due to absense of a fridge, I have to store milk between two frames of a window. When it's too cold the milk can freeze as a result. As you probably know, milk has quite complex structure of proteins, fat and water. What happens when the milk is frozen and then unfrozen back? Does it lose any properties, or it is reversible operation? Grue 07:37, 23 January 2006 (UTC)

This is in reference to a mail i got from one of my friends.. According to the mail a 10yr boy was infected with AIDS, because he ate food from a road-side dhaba(small hotel). The cook had a cut in his hand and he was infected with the virus(without his knowledge). So the blood from the cook's hand went to the food and it inturn went inside the boy causing the boy to be affected. Can this be true?? Can anyone plese confirm on this..

If there is some one out there developing .NET applications for Windows CE, you could help me. I'm evaluating the possibilities to migrate from PLC control in an application (which I would rather keep to myself which one it is) to using computers instead - and I've already done successful test "concept" applications on Windows XP using .NET Framework version 2. However, if it is possible to use Windows instead / in combination with Windows XP that could mean a cheaper/better overall solution.
I'm wondering what kind of development platform is necessary on the development PC, to develop applications for Windows CE, including deploying them to a smaller number of devices with preinstalled Windows CE 4.2 and/or 5.0. I'm trying to understand by looking at microsoft.com, but it's hard to find the right stuff there as it is such a big website, there's loads of marketingspeak, and most of the actually useful info is for the old version of Visual Studio, 2003, and I'm using 2005 standard edition. Also note that I'm mostly interested in development of applications, but I would also have to be able to install them for it really being usable. :)
I would get devices with Windows CE preinstalled. Most of the tutorials mention a program named "Platform Builder", is that really necessary for application development only? Also many of the 2003 tutorials mention that there is a Windows CE emulator in Visual Studio 2005, but it seems to have been cut (there are PocketPC emulation included though). I am also missing the "CAB Build" option that is described in the VS 2003 tutorials... Basically, any feedback would be greatly appreciated! 62.119.184.141 13:16, 23 January 2006 (UTC)
HELP! i'm getting desperate. does anyone have a solution to this diagnosis.
i have had a ct, mri, abr, audiology, medication, antihistimines, with little success. all tests were negative. the sound has become so severe that it wakes me up at night and i have three distinct sound levels at the same time: hissing, ringing and bells. all sounds are different frequencies.
hearing aides for white noise did not help. tomos and panorex showed no symptomology,and i had never been exposed to loud noise so that rules out structural deviation.
so what do i do? i'm becoming very frustrated and agitated due to the constant noise.

Make sure you aren't taking any meds which contain aspirin, although your problems sound beyond those typically caused by that. Also check all the other meds you regularly take (including birth control) for any mention of tinnitus as a side effect. You might also want to look each up on the internet as it may still cause tinnitus and just not have it listed.
You didn't say whether it's in both ears or one. If just one, I would think that would indicate a problem with the ear itself or the immediate surroundings, such as a partially blocked eustachian tube. StuRat 16:05, 23 January 2006 (UTC)

Unfortunately, because the speeds are typically rounded to whole numbers in any of three different units, errors are often introduced when the table is copied.) --Anonymous, 04:40 UTC, January 24.
Two points, living in Tokyo I usually hear that hurricanes are considered stronger than typhoons, and though I haven't seen any figures I'd like to agree with that. There are usually close to 20 (named) typhoons in the typhoon season every year, and in fact quite a few of them hit Tokyo and Osaka (there is a fair chance that it could hit both cities). Tokyo was hit/grazed/passed over at least 2 times last season (fall, 2005) but it depends on what you mean by 'hit'.

I remember watching a documentary about the brain a while back that gave some information on an experiment (I believe by 2 amateur scientists) in sharing brainwaves (for the hell of it). I think the experiment was performed in the late 70s or 80s, and it was probably done with the pretext that it might be possible to enduce telepathy by amplifying brain patterns. I don't remember details of the experiment, other than the fact that it may have done with both subjects simultaneously or with recorded brain waves from one subject, and the results were simply that the brain couldn't handle/understand the input and the scientists were rather disturbed by the experience, so they gave up.

I'm sure everyone's seen a sci-fi movie with teleporters, like Star Trek or The Fly. My question is, if the machine is just reading all the cells in your body, and "beaming it" somewhere else (presumably they're destroying the body and transmitting the 'plans' to another body-producing machine), wouldn't this technically kill you? I mean, there would be another person with your thoughts, memories, that was identical, but your brain would actually be destroyed and your consciousness interrupted, so wouldn't you be dead?
I'm uncertain of the concepts behind teleportation and how to phrase my question, but it's a very interesting issue.
There is the issue of transporting the "soul"...at least for those who believe souls are attached to our bodies. Some religious people might very well argue that you have actually murdered the real person and created a souless duplicate. I suspect the anti-stem cell research people would be the ones who would move to have the process banned.
Also, some method would be needed to "jump start" the new copy. That is, the heart beat and other body rythms which had been interrupted would need to be restarted. Your thoughts would certainly be interrupted, perhaps like the shocks in electroshock therapy.
Note that the technology for a very crude transporter exists already. An object can be scanned with a CAT scan or other device, this info can be sent anywhere, then a new object can be created via rapid prototyping methods. The materials are limited to the plastic from the SLA process or the "wood" from the LOM process, and the resolution and size are also limited, and the full process will take hours, but the basic idea is there. All that is needed now are some refinements (which may take a few hundred years) before we can transport people.
Also note that only transporting from one "transporter station" to another would be possible. The idea of transporting to a place without a station to assemble the molecules seems impossible to me. And sending the actual molecules or energy to the new site seems similarly absurd. Only the information need be sent, so that molecules and atoms at the new site can then be assembled into the final object. StuRat 19:55, 24 January 2006 (UTC)
Also note that the technology to transport a retrovirus, some of which are basically just RNA, may exist in just a few years. We can scan DNA or RNA, transmit the info, and assemble DNA or RNA at the other end now. All that is needed is to increase the speed and accuracy to a point where an entire retrovirus can be produced reliably. Some consider a retrovirus to be alive, since they reproduce and evolved from more complex life forms. So, this will be quite a first step toward transporting living things. StuRat 20:37, 24 January 2006 (UTC)
One type of transporter might scan an object, disassemble it, transmit its structure to a remote device, and the remote device construct a new version of the object from its own supply of raw materials. Of course, if the initial device didn't destroy the object after scanning it, you would end up with a copy of the object as mentioned above. In contrast, transporters on Star Trek do not only transmit information. The matter itself is beamed (the "matter stream") to the remote location. This, of course, is why people and objects can be beamed to locations without a transporter, like the surface of a planet; if only information is being transmitted, a receiving device with a supply of raw material must be present. It is also why transporting is limited to a short range around the transmitter; if only information were being transmitted, then presumably one could transmit the information from relay to relay to reconstruct someone many light years away. — Knowledge Seeker দ 01:00, 25 January 2006 (UTC)
Matter Transmission existed in science fiction "literature" long before Hollywood popularized it and hijacked the terminology, confusing the ethical concepts.

Does anyone know of a mental disease or disorder which causes a person to intensely regret things which have happened in their life? Particularly things they have done? Captain Jackson 19:03, 24 January 2006 (UTC)
Hmmm. I've read your response about 6 times now and still find myself a bit baffled by it, I must admit.
The proof that you're asking for.
It was just an example to contrast with diagnosis. Red eye means red eye, not 'red eye v2', or 'suspected red eye', etc.
Simply that symptoms relative to diagnoses can be easily defined and classified (note: relative) whereas diseases, even when understood take on unpredictable characteristics.
the original statement was "No mental disease or disorder can be diagnosed merely from a single symptom". Your statement was "You are in no position to know ... if there are examples of mental diseases or disorders that have a single symptom". I'm sure what you meant to say here was "if it is possible to deduce diseases or disorders from a single symptom or not".
You have made many arguments, in fact I'm losing track. The basic structure of your argument is that it's impossible to deduce A from B when you lack the knowledge to do so, and I'm saying that equally it's impossible to assume that such a one to one correspondence is even POSSIBLE to exist because of the same reason. In fact, I'm not even sure that your argument even EXISTS, or that I'm even argueing about this argument ... ahhh I'm lost in paradoxes. freshgavin TALK 00:43, 26 January 2006 (UTC)

Why aren't there sex-linked diseases that are carried on the Y chromosome (or are there)?
I think this is a plot by the female gender. (CABAL!) — Ilyan e p (Talk) 01:31, 25 January 2006 (UTC)
Because there is little essential information carried on the Y chromosome. Every human has an X, but 50% of the human race lacks a Y, so it has to be dispensable. The only significant Y linked disease is the absence or nonfunction of SRY, which leads to sex reversal (XY genotype, female phenotype). It's a genetically "dead-end" condition because they are usually not fertile. alteripse 01:38, 25 January 2006 (UTC)
Also, I'm fairly cetain that there are some, though not many. The reason for this is twofold. One, any major life-threatening diseases can only be transferred directly from father to son. Another is that there are no carriers. Females aren't affected by sex-linked diseases as much because most of those diseases are found on the X chromosone. Since they have two X chroms, unless both chroms are affected, the unaffected X chrom just takes over. In this way, they have a chance of being unnafected but passing on a defected X. An affected Male Y chromosone doesn't have another Y who can take over. --
Herzog 01:44, 25 January 2006 (UTC)
Several types of azoospermia are linked to mutations in genes on the Y chromosome. But because these conditions decrease fertility, there is a strong evolutionary bias against them. -- WS 13:14, 26 January 2006 (UTC) The Sex linkage article comes close to defining sex-linked disease genes as being on the X chromosome. Some genetics texts seem reluctant to describe Y-linked defects as sex-linked disease ( example).

What is the technological reason for using any interlaced video format with HDTV? As far as I understand the interlacing technique was invented to get around the fluorescent's short persistence phenomenon, in order to reduce flickering on Cathode Ray Tube displays (CRTs). With the invention of the plasma screens and since HDTV targets mostly those screens, this technique seems to be obsolete and not necessary anymore (plasma screens do not suffer from the short persistence like CRTs). I expected any new format to abandon the interlacing technology completely and concentrate on compression using the modern technology (Spatial / Temporal redundancy reduction using Motion Compensation and DCT). Transmitting 60 fields per second or 30 full frames per second consumes the same bandwidth however if the video is interlaced the receiver must de-interlace it, which consumes serious amount of CPU power and result in inferior quality.
Why we are still using interlaced video for HDTV???

The reason I ask is that I regularly eat (frozen) spinach, to which I add milk, feta and lemon juice, which requires reheating. If there is any truth in the story, does it apply to this or only to serious cooling (eg in the fridge to eat the next day)?

The lab this week was reducing benzil to form a diastereoisomeric diol, then determining which form you got (RR, RS, SS.) I've solved all the subsequent problems to do with the formation of a cyclic ketal, and I'm certain that the product I got was meso-, but I can't figure out why it was. I'm guessing there has to be some sort of steric factor, but that alone isn't going to cut it in a write-up, and playing around with my models, I can't see why only the meso-form is produced from the reduction. Any hints from the amazing Wiki-mind? 81.132.176.76 01:18, 26 January 2006 (UTC)
What is a "head to head" clinical trial?
Matching two similar treatments to see which is better. For example, recruiting the next 20 patients with ear infections for a trial. Randomize 10 to receive 10 days of stompicillin, and give the other 10 patients 10 days of homeopathic gopher pellets. Measure all the relevant clinical parameters you can think of, such as fluid remaining in the ear at 10 and 20 days, number of days until pain gone, number of days until fever gone, number of days of school or work missed, and so forth. If this was your idea, you write it up for a medical journal. If this was sponsored by the makers of stompacillin they either publicize the results to every doctor in the US or bury the results (depending on the results of course). alteripse 02:36, 26 January 2006 (UTC)

How many satellites do you need to be able to see the whole surface of a planet from at least one of them at any moment? If the size of the planet matters, it's about half earth radius.

In reference to the theoretical rather than the real-world version of the problem, four is the minimum number of points you need to be able to view the whole world from them. Two points opposite each other leave a ring uncovered (since they can't be at infinite distance), and three points in a triangle leave two poles uncovered. But the question asked about satellites, not points in space. A satellite's orbit has to lie in a plane that passes through the center of the Earth, so it's not possible to have 4 satellites maintain a tetrahedral configuration.
There is an easy solution using 6 satellites: just put 3 each in two perpendicular orbits, e.g. an equatorial orbit and a polar orbit, spacing them equally around each orbit. By arranging things more trickily, you can do it with 5. But when this question was asked in the newsgroup rec.puzzles in 1994, Stein Kulseth topped that with this clever solution using 4 satellites in orbits that are nearly, but not quite, circular, and each in a slightly different orbital plane.
For real-world practicality, the 6-satellite solution would probably be best. --Anonymous, 08:10 UTC, January 26, 2006.

I recently bought a cheap stainless steel pot from IKEA, and have noticed that when using it to boil water (practically all I've used it for) it gives off quite a harsh, chemical, metallic smell.

If you've ever boiled water and 'forgotten' about the pan that could be your culprit. I've burned at least 1 pan that way and it gives off a horrible smell after that, even to the point that it made my eggs smell bad too. I didn't die but I threw the pan away soon after that; it was only about $2. freshgavin TALK 23:44, 26 January 2006 (UTC)

We have a constant problem with computer support here. You give a person a website over the phone or through email. They say it doesn't come up. You test it and it works. After going back and forth, you walk over to the next building and watch them type the URL in Google's search box and hit enter. This isn't a one-time issue. This happens over and over and over. I've even asked people, "Are you typing the address into Google or the address bar?" They say they are typing it into the address bar, but when you check, they are typing it into Google. Is this an anomoly of Google idiots here or is this a problem others have?

Both of my parents do the exact thing you describe, have done so for years, and steadfastly refuse to change their habits because the way they do it is "good enough" for them. (Nor are they willing to learn the meaning of the most basic terms such as "address bar". I haven't even been able to get them to understand that they can have more than one browser window open at the same time; I'm afraid to bring up the concept of tabs.) Short of changing the home page in their browsers to a blank screen (which would probably result in them cutting me out of their will), I don't see what can be done about it. All you can do is figure out some way of phrasing your question so you can at least be able to tell whether your given idiot valued employee is actually using the address bar or not and then ordering them to try the address bar if they haven't already. Perhaps something like, "Do you see the line of icons at the top of the window that say 'Back', 'forward', 'reload', and so on? You do? Goooood. Now see that long white box to the right of it? Goooood. Now take your mouse and point it at the pretty long white box ...

It would be neat to test this scientifically. We could come up with something similar to tests for color-blindness, a series of dots with only a subtle color difference, that, if detected, allows you to see a hidden picture. If you couldn't make out the pic normally, but could after eating spicy foods, that would be proof that it works. Even more exciting would be if nobody else could see the pic, but only you could after eating the spice. This would prove it's not just a perception issue, but that your eyesight really was enhanced over a normal person's eyesight. If that was the case, isolating the chemical(s) causing this effect would be the next step, leading to a new nutritional supplement. StuRat 08:00, 27 January 2006 (UTC)

I'm not convinced of the feasibility of a space elevator. Finding materials which can withstand the forces would be quite an issue. Assuming they are found, and the elevator shaft can be built for a mere million dollars per kilometer, at a height of 35,786 km that would still be 36 trillion dollars, which nobody seems to have just lying around. If a world effort was made to build it (over decades), then some political method would be needed to assure access to it by the contributors. This would be similar to issues with the Suez and Panama canals. Nobody would be willing to contribute that much money without knowing they have permanent access to the result. Perhaps an "international zone", similar to Antarctica, could be established around the base to prevent the surrounding country from having veto power over who can use it.

The term "human", in common usage, refers specifically to Homo sapiens. However, broadly speaking, it may also refer to any members of the genus Homo. See [95] (click on second definition, "noun"). Or for instance, when Homo floresiensis was discovered, Scientific American called it "The Littlest Human" on its cover. You will often find "modern humans" or "anatomically modern humans" written in texts dealing with human evolution to differentiate us from our close ancestors. — Knowledge Seeker দ 07:05, 27 January 2006 (UTC)
Another nitpick. The name hominid properly refers to a species in the family Hominidae, which is generally considered to include humans and the great apes — gorillas, chimpanzees and orangutans. Unfortunately there isn't a widely-understood scientific term meaning "modern humans and other hominids more closely related to humans than chimpanzees". In some classifications this group is classified as the subtribe Hominina, so you could try using the term homininan. But few people will understand what you mean. Gdr 12:23, 27 January 2006 (UTC)

Hi, I read in my sceince text book that it can be possible to use water as a fuel for the cars in near future. Hydrogen and Oxygen is diffused by electrolysis and the produced Hydrogen is combusted for producing energy.After combustion the Hydrogen gets oxydized and again forms water. But there are some problems like its difficult to control the combustion of Hydrogen because its like a blast. and because after combustion it form water in exhaust making it wet and electrolysis of water on large scale to produce enough energy to drive a car. But would it be possible to do this? If yes then it would be very revolutionary step in the world of science. Any explaination would be thankful. -- Manasmdk 10:54, 27 January 2006 (UTC)manasmdk
Hydrogen explosions are not difficult to control. Internal combustion engines use explosions all the time. There's also no problem with forming water in exhaust - bear in mind other fuels - gasoline, etc. produce water during combustion as well, as they are carbohydrates...in fact most of the energy in these fuels come from the release of protons (hydrogen) and high energy electrons which had been earlier stored in organic material for decades...when combined with a highly electronegative element like oxygen, energy is produced. Hydrogen doesn't have the high energy bond, but it still remains the primary source of energy in a fuel...so pure hydrogen is a fuel in itself. The problem is in its density - organic molecules tend to have more mass over less space because of intermolecular forces as well as sharing of electron orbital pairs, thereby making lots of fuels a liquid (including ethanol and gasoline)...for example propane or methane are less so (which is why it isn't often an automobile fuel). The difference is that gasoline might contain many impurities and pollutants, nitrites, sulfides, sulphates, etc. making it impure, when hydrogen would have no such mixtures. This is because organic matter such as plants extract minerals from the soil during their life, incorporate sulfur and nitrogen into their amino acids - when the proteins (made up of amino acids) decompose, the sulfur and the nitrogen in them breaks off and forms new compounds in the organic matter and become pollutants when burnt (forming nitrogen oxide, sulfur oxide, etc..

Thnx in advance.
The fundamental problem is that WMA format is not designed to let you do what you want to do here. Moreover, it is specifically designed not to let you do what you want to do here. Microsoft doesn't want you converting those WMA files into any other format at all (let alone the popular but unprotected mp3 format), because in this case, it is more interested in keeping the record companies happy than it is in keeping you happy.
There are probably programs out there that can convert from WMA to mp3, but they are not going to be easy to find, because if they were easy to find, Microsoft would have found them and gotten them suppressed under the DMCA. There are probably people (here) who could tell you about those programs, but they're reluctant to, because telling people how to defeat copy protection can get you in almost as much trouble as defeating copy protection, which can get you in almost as much trouble (more trouble, really) than actually violating copyright.

Discussions about electric bills often come up where I work, and the issue of power factor relating to what you use and what you're billed for is often raised. Many suggest that the utility company charges for the uncorrected power you use, using peak current. This would mean that they are actually charging for KVA/H instead of KW/H, which would be deceptive at best. Does anyone know the metering method of typical house KW/H boxes that the util co's use to charge for power in the US? I didn't find much specific info in our Electricity Distribution category. -- Jmeden2000 17:43, 27 January 2006 (UTC)
Not to stop anyone from pondering this... but I found a fairly good answer after more reading in the Electric Power category's article on Electricity meter (should that article be attached to Category:Electricity_distribution?), which explains that most common meters use a method that does not account for reactive power and hence would meter true wattage. Although, it's not terribly specific so if anyone has more info I would love to hear it. -- Jmeden2000 18:43, 27 January 2006 (UTC)
I'd like to point out that, as long as all power companies do it the same way, it doesn't matter, since they charge whatever either competition or the state governments will let them get away with. For example, if a utility sells one billion tweebles of power each year and it costs them a billion dollars, the state government may allow them to charge $1.10 per tweeble for a fair profit of 10%. On the other hand, if they claim they sell two billion tweebles a year at a cost of a billion dollars, the state would allow them to charge $0.55 per tweeble for a fair profit of 10%. So, the cost to the consumers will be $1.1 billion, either way you do it. In areas where different power companies compete, the forces of competition would dictate a similar outcome.

hahaha! yeah I'd rather have snails crawl on me than use some dubious cream on my skin...I'll stay with my skepticism and not expose my skin to any risk.-- Cosmic girl 19:40, 28 January 2006 (UTC)

I need all the information I can get about battery discharge. I am participating in my local science fair and I need info to write the essay. I have been searching on the internet but all of the info is not quite right. I need to know about battery discharge in AA Alkaline batteries. Just the common household ones like Duracell and Energizer. I really Appreciate it, Thanks!
Thanks, but I have already searched exstensively there, and have not found the info I was looking for. I need to answer a few questions: What is battery discharge? WHat does storing a battery in a cold temperature do? What does storing a battery at room temperature do? and What is the best way to store a battery? If you could answer these questions that would be great. Thanks! P.S.: I am looking for answers about non-rechargable batteries
Those are decent questions. They all boil down to one question though: What causes batteries to self-discharge? We should really have an article on self-discharging. -- Ec5618 21:24, 28 January 2006 (UTC)

Hi could someone tell me how long it takes vicodin to clear ones system , so it would not be detected in a urine test? Thanks Carl
I think there is another way of understanding what the 72 hour urine sample means. The recovery of 26% [111] during 72 hours is part of the analysis of total drug disposition (e.g., about 26% is excreted unchanged in the urine as opposed to being metabolized to other substances in the body). It almost certainly does not mean "...leaving 74% of the drug to be excreted over the next few days."
Unfortunately that figure does not give us the info to answer the question, which appears to be "how many days after ingestion of some vicodin will it no longer be detectable by a standard commercial urine drug screen?" I do not know the answer, but it would almost certainly depend on the amount ingested in the 2-3 days prior to stopping. The best answer might be found by googling for websites that coach people on beating drug tests, or the commercial sites of companies that make drug screening tests for employers and law enforcement. This is not a topic I have expertise in so I don't know what is readily available online. alteripse 17:27, 29 January 2006 (UTC)

There's been a lot of hype concerning the whole future hydrogen society. But I was sort of wondering why I would be so great...
A vehicle needs X energy to travel from point A to point B. It's irrelevant whether this energy comes from oil, gas, ethanol or hydrogen - X remains constant. So, you can collect solar energy in mechanical solar cells and "store" it in hydrogen or you can collect solar energy in organic solar cells (crops) and "store" it in ethanol.
So the question is - if the basic principles are so similar - why would hydrogen be better than ethanol...?

Lots of people have been on and off lithium or any other psychotropic drug. The problem with psychotropics is that there is no blood test that tells a psychiatrist exactly what disease a person with a mood problem has, and how much benefit can be expected from a given psychotropic drug. Therefore many people try more than one over a period of months or years before finding one that helps or finding other resolutions. Persevere and good luck. alteripse 00:36, 30 January 2006 (UTC)

Are there any natural lakes (not manmade) in Ohio besides Lake Erie?
I got this idea to make a system to protect the earth from asteroids.
1)A giant pipe 30kms long, 500m wide with 60cm thick walls would be built out of some metal (steel)
2)It would be put into an isolated part of the southern ocean.
3)A giant empty spherical durable metal foil bag 1/4 the size of the moon would be loaded into the pipe.
4)Ocean water would be pumped into the bag (ocean wildlife issues would be taken care of beforehand)
5)When the bag is full it would be pushed with rockets higher so that the water would freeze
6)The new moon would be in earth's orbit until needed, then it would be blasted towards the asteroid to deflect it.
!!!!!!!!!The new moon could also just be to look nice!!!!!!!!!!
>>>How much do you reckon this would cost? (I'm planning to make this as a weekend project)
PROS: asteroid sheild, all the water taken off earth would expose extra land, the tube could be remelted and used.
CON: cost
--Anonymous~Thinker `.............................................................
+(BTW, I'm the guy who made this question) The ice moon would be smaller and easier to move then the real moon. ALSO: the moon isn't meant to be a 'sheild' per se, it would simply be boosted with rockets towards the asteroid long before the asteroid would actually reach earth, to deflect it (the asteroid). I originally thought that the ice moon could be covered with giant screens on one side and solar cells on the other. The screens would play comercials 24/7. Or they could be used to display the current time (the time would change, and display the times of different time zones). +Now, the cost would be 5yottadollars...so how much money exists on all of earth at this time?
User:AlMac| (talk) 08:56, 31 January 2006 (UTC)
+Elaborating on what was said, the ice moon wouldn't be made, and then lifted. It would be filled while 30kms about earth, so it would just need to be boosted. Incase someone doesn't get it, I'm including a picture. File:Earthplan.JPG

In the month of January I find myself blowing my nose more often than I do the rest of the year put together. Question: Is it better for the environment to put my used tissue in the bin or in the toilet (flushing only when I would usually flush, of course)?
I'm wodering if we're tackling this question the right way. The question as posed has quite a number of variables, and we've been neglecting one of them. If the hanky is left in the bin, then the germs will still be in the household environment until the bin is emptied. A cloth handkerchief, while better environmentally than a paper hanky, will compound the problem, since you'll be carrying the germs in your pocket. Toilets usually contain anti-germ treatments in the "cistern blue" fresheners, so from that point of view at least toilet disposal has advantages. Grutness... wha? 02:13, 31 January 2006 (UTC)

I'm trying to achieve what I thought would be a very straightforward effect -- a header with several items spaced evenly across the top of the page. It's trivial to do with tables, but I've spent the better part of a day struggling with a solution based on div
elements and CSS, with no success.
In particular, I would like to set the widths of the items as percentages of the width of an enclosing div
element. I thought that using percentages with the width
attribute would do this, but the results I observe do not seem to follow this rule.
This is a stripped down version of the HTML:
<html> <head> <link rel="stylesheet" type="text/css" href="index.css"> </head> <body> <!-- This works --> <table class="header"> <tr> <td class="header_left"> Logo </td> <td class="header_middle"> Welcome to my site. </td> <td class="header_right"> <a href="contactus">Contact us</a> </td> </tr> </div> <!-- This doesn't work --> <div class="header"> <div class="header_left"> Logo </div> <div class="header_middle"> Welcome to my site. </div> <div class="header_right"> <a href="contactus">Contact us</a> </div> </div> </body> </html>
and the stylesheet:
body { background: gray; } .header { background: white; width: 100%; } .header_left, .header_middle, .header_right { display: table-cell; background: lightgray; text-align: center; } .header_left { width: 25%; } .header_middle { width: 50%; } .header_right { width: 25%; }

I wonder, what is the minimum time it would take to terraform a planet like Mars?A few hundered years?A few thousand years?Hundreds of thousands of years?(Let's suppose we spend a minimum of ten billion US dollars on the project every year.)
In terms of the finished result, a terraformed Venus would be a more attractive prospect than a terraformed Mars. However, it would be a far more difficult task to achieve and would take tens of thousands of years with our current technology level, if it were possible at all. The planet's atmosphere is deadly, and cleaning it would be extremely difficult, although some forms of terrestrial lichens and mosses could probably just about survive it the way it is now and might be utilised to improve it a little. Mars is probably the easier bet if we wanted to try any terraforming, and has the added advantage that we know that several useful chemicals are available on or just below the planet's surface that could be used in the process.

I'm not sure what the author of the book you cite might refer to, but it's true that quantum mechanics allows the creation of temporary virtual particles from nothing. Some popular science theories have indeed suggested that the big bang might amount to little more than an unusually big vacuum fluctuation from which the matter and energy that makes up the universe emerged. Such an event would be incredibly unlikely, but, given limitless time, might nonetheless be expected to occur eventually. This could be taken to imply that the entire universe is virtual, composed of matter and energy that only exist temporarily. — Ilmari Karonen ( talk) 15:17, 1 January 2006 (UTC)

I am not going to argue the case one way or the other here. But here are some observations of mine concerning the question for the affirmative. Whether evolution is true or not is still based largely on personal convictions rather than solid evidence, from both sides of the camp.
TRANSITIONAL FOSSILS All the transitional fossils that I have read I stress 'READ' because I, like many others, only know what we have been told about amount to no better than the statement
"Pine cones have spirals that radiate in the same direction as snails".
Obviously this fact does not prove that snails evolved from pine trees. Yet, statements similar to this are used to proove that an animal that obviously belongs to a single species is actually a transition from one species to another. A transitional species should be an animal that obviously belongs to two different species and yet dosn't completely belong to either. Otherwise it is just proof that over time a particular species can adapt it's physical characteristics to suit it's particular environment. Black moth, white moth, they are all still moths with differnt adaptations, there is no proof of evolution from one species ino another different species there.
MAN EVOLVED FROM APE Scientists trace mans evolution from apes via cranial capcity and tool use. Yet I have read the question asked, If Austalopithicus were alive today, would we see it as a man or an ape? Answer: Ape. The fact that he used tools is evidence of his link to man. But don't chimpansees and apes alive today also use tools. Aren't there even members from other species not supposedly related to man that it has been said that they use tools. I have also read the question, If homo erectus were alive today, would we see it as a man or an ape? Answer: Man. His smaller cranial capacity is used to proove his relation to ape. So does that mean there is no variation in cranial capacity with people alive today?
DNA EVIDENCE The fact that various sequences of DNA are repeated almost unchanged from one species to another is cited as proof of evolution. However, the way I see it is that IF life was indeed created, then I would expect to see that the basic building blocks were reused over and over. This could also be seen as evidence of the handiwork of a single creator. Why change something that works. For example, If I were a car manufacturer, then why would I change the basic design of the wheel just because I now wanted to manufacture trucks, or planes or wheelbarrows.
All of the so called proofs of evolution that I have been 'TOLD' about are merely proof of the variation that can occur within a single species based on it's environment. This is called Adaptation. They are not proof that a species can evolve into a completely different species. This is called Evolution. In short Adaptation is not proof of Evolution.

Copernicus hardly said anything new (see Heliocentrism) Probably won't even figure in my top 100. deeptrivia ( talk) 23:01, 1 January 2006 (UTC)
And then there's Tycho Brahe. although he was mostly good at collecting top scientists around him. And Mendeleyev; the period table represents quite a jump in our understanding of the world. The argument against Copernicus also goes for Darwin, I believe, because he also largely just regurgitated things that had been though of before but no-one dared say out loud. But all this and the above all focus on fairly recent (and western) history. There were quite a few impressive scientists in old Arabia and India, although I can't think of any names from the top of my head. For an extensive list of more recent names you could also look at the list of Nobel Prize winners. DirkvdM 12:40, 2 January 2006 (UTC)
(no question) To an atheist, religion serves the purpose of enforcing morality. Such morality is represented in the political stances of many people. Such morality rejects the legalization of any immoral activities. However in some circumstances, the war may have been lost already. In that instance a mitigating stance may be adopted. The moral decision picks the least of evils.
With such a perspective, a fellow may think that on most fronts that all moral people will be united. But some people have different definitions of morality. While strategy may require an otherwise moral person to refrain from a verbal attack on an immoral activity, in execution the immoral activity should be suppressed by that person to his/her greatest ability.
This strategic restraint can and will invite attack by under informed people. These people see the absence of endorsement, but not declaration of the immoral activity as acceptable as permission. (Explicit endorsement of an immoral activity encourages it and thus is immoral)
This strident attack, by people who do not accept strategy as a reason for ambivalence, is reflected in many areas of human interaction. Most organizations that operate from moral grounds, PETA, Greenpeace, etc, AND act aggressively upon their beliefs are marginalized by the majority of people who would prefer a more strategic approach. Anyone who does not agree with their strict beliefs are refused entry into their group.
A majority of people eat meat and yet a majority of people do not want animals killed in a sadistic manor. These states of opinion do irrecoverably clash because people desire efficient production of food, aka cheap food. The swiftest form of death is often thought to be the most desirable. Death by lethal injection may be therefore reserved for non-edible animals due to obvious safety concerns, and its inefficiency.
One important issue today is stem cell research. One of the methods harvests the immature human at a stage of non-specialization in the womb. For anyone who defines a human by his/her sophistication this is not a problem. This criterion has been used to justify excluding animals from being held as sacred life, and thus fodder for experiments and humans. Also people have been excluded via this criterion. As Darwin's theory makes clear the competition between the races leads to the exclusion of one to the success of the fitter race. To clarify, the better race will, via natural selection, be the last standing. The survival of a large group statistically accounts for random events.
The implications of natural's law should inform the thinking person. But sophistication and thus superiority as the basis of humanity is liable to the standard slippery slope argument.
The logic which defends natural law as moral hold that natural law is logical. Humans could not live together with free will if saddening things could not occur. Humans see part of morality as mitigating such sad events. The other part is avoidance of creating such events.
Returning to the stem cell research logic defines the basis of the decision to allow such an activity to occur legally as: 1. What is the boundary of human life? 2. What is the moral stance of the nation? 3. To what extent can this moral stance be applied to law?
Obviously protected and defensible life cannot exist before conception as the cells of reproduction have a transient lifetime before being discarded. After birth, by the laws of most civilizations, a babe is protected human life. At external viability, a babe merely needs to stay inside the mother to maximize the odds of survival. Between this and conception the picture is less than clear for the U.S. Supreme Court.
As moral people cannot accept an immoral activity, and will condemn even those who refrain from explicitly stating opposition to an immoral activity (who do have plausible reasons for the silence- such as lack of hard evidence) the Court's decision is immoral by someone's standard.
The U.S. as a whole finds any destruction of immature humans to be undesirable. Yet the degree to which it is abominable is debated. Some see the religious conservative's certainty that no uncertainty can be allowed in life or death moral decisions as mere dogma. Others see the lack of certainty prohibits government interference except for safety. Still another viewpoint observes that one's privacy should not be encroached upon, thus limiting government from informing any other person about a decision of this nature.
Obviously Americans allow uncertainty in the moral decisions of their leaders concerning law. Merely because in a plausible circumstance an activity would be inhumanly abominable does not mean that it must be prohibited. If some benefit is gained, even if such benefit is dubious, the potential benefit to future people justifies the risk of an immoral action.
However the U.S. government has allowed those people with no stomach for potential abomination to know that they do not contribute to this questionable activity. While not stopping a crime if it is in one's power to stop is immoral, holding oneself back when victory is not guaranteed is prudent and acceptable. Futility is an acceptable explanation for inaction. So the government does not fund the research except on cells already acquired. It is meaningless and immoral to allow a resource that exists to be squandered. However if the resource is immorally acquired one can "use the ivory while hunting the elephant hunter."
Also practically a police state will not be enacted by people worried about political morality. Such a state would expand the government beyond the desires of any American, and invite close regulation of business. While some people have no objections to the enlargement of government others fear even the local police.
An intolerance for questionable moral activity may appear to be mere grandstanding and hypocritical. Certainly the fact that religious organizations are not the primary source of aid for people who are having difficulties, especially financial difficulties, diminishes their ability for undisputable good works. Religion does not school thousands of children in morality. The social network that would allow people's mutual morality to reinforce each other does not cover without holes large areas. The control which church leaders have over their members is not as absolute as is necessary to judge the whole by parts.
Some atheists contend that religiosity is applicable only to private practice. Such people often have a low opinion of religious people. But to fairly judge religion's effect on society depends on an ability to separate it from the society. That is impossible. Therefore religiosity must be judged on its present pursuits.
The insistence on an incontrovertible policy on a moral issue is admirable even to atheists, who can and should respect the unwillingness to compromise principles and/or morality. When one judges atheist's perspectives their unwillingness to claim a heritage in history- due to the typically human mixture of events- one must do so on their present stances.
Morality is universal. To compromise it invites dissolution of all principles to the transient needs of the present.

Do you drink public water? The earliest sign of water commodification occurred over the last decade when the middle and upper classes stopped insisting that everyone have access to high quality drinking water, just as they abandoned the commitment that even children of poor parents have access to good education or crime-free neighborhoods. Both the water supply and the public schools in most large American cities have dropped below the level which upper middle class people consider acceptable. Those who can afford to drink bottled water and send their children to private schools do so, just as they pay for security in their own neighborhoods. Once you no longer rely on public drinking water, public schools, public libraries, and the police, it is easy to vote for politicians who promise to cut the taxes of the rich, as long as the streets, schools, and water are "safe enough" for other people's children.

Peritoneum is the abdominal space. Mesothelium is the membrane that lines it. In medical contexts the word peritoneum is used over a thousand times more often than mesothelium; in fact, peritoneal lining would be a clearer term to most doctors than mesothelium. alteripse 02:27, 2 January 2006 (UTC)
My understanding is that peritoneum is the serous membrane that lines the peritoneal cavity and consists of parietal and visceral subtypes depending on what it is attached to. Mesothelium, a part of peritoneum, is the single layer of flattened cells which overlies the areolar connective tissue base (which varies in thickness depending on its location and functional requirements). This is analogous to skin, for example, which has an epithelium covering the deeper connective tissue matrix of the dermis. Thats basically what my anatomy text says, anyhow. And it seems consistent with Stedmans definitions (see above). Mattopaedia 03:20, 2 January 2006 (UTC)

I just want to make sure I've got this correct. The coelom or pseudocoel (depending on the animal) develop from the mesothelium and (in the case of coelom) become the peritoneum. TheLimbicOne 03:54, 2 January 2006 (UTC)

Short answer: Because it had a beginning and is finite (see Olber's paradox). deeptrivia ( talk) 04:27, 2 January 2006 (UTC)
To ask a more elaborate question:
Who was it again who is credited with coming up with this question? One answer would of course be that the assumption is wrong the universe is actually finite (as already stated). But another answer is that there is dark matter that obstructs much of the light. Wasn't there more? DirkvdM 15:20, 2 January 2006 (UTC)
If the universe is finite but unbounded, there must be geodesics which loop back around to where they started. So, there should be images of the Milky Way galaxy (or even larger structures that contain it) that appear to be very far away. If we saw one of these images with a telescope, would we recognize it? Is anyone specifically looking for them? It would be a pretty big breakthrough for cosmology if they were found, right? — Keenan Pepper 07:12, 2 January 2006 (UTC)

indeed your assumptions are correct and i understand and value your response but i would still like to know whether there is any 'scientific theory' or evidence that states that if a cell is left in a specific solution (say 1M sucrose solution)for a extensive period of time it will be damaged, such that it will not be able to carry out diffusion to the same efficiency..on which i can base my reasonings for a proposed method in a experiment.

what is the cuase of dental decay?
Dietary sugars and starches increase the risk of tooth decay. The type of carbohydrate and the timing and frequency of ingestion are more important than the amount. Sticky foods are more harmful than nonsticky foods because they remain on the surface of the teeth. Frequent snacking increases the time that acids are in contact with the surface of the tooth. Yay that's all.-- Mac Davis ญƛ. 05:16, 3 January 2006 (UTC)
To return to the original poster's question, the only unequivocal facts about dental caries (tooth decay) is that three things must be present for it to occur:
That a tooth is necessary is self-evident. The other two factors have been demonstrated experimentally by using strains of germ-free rats, which do not experience dental caries until they are innoculated with cariogenic (decay-causing) bacteria and fed carbohydrate by mouth.
This does not begin to explain the wide variability of caries experience among individuals. There are more than a few cases where the bacterial load in a given mouth is off the charts due to poor oral hygiene and poor diet, yet tooth decay is absent. The converse is also true: excellent oral hygiene and attention to diet does not assure that tooth decay will not occur or even that it will not be rampant. This suggests that there are other factors that influence the incidence and severity of tooth decay-- whether it is some intrinsic quality in a particular person's tooth enamel, salivary antibodies, salivary enzymes, or some environmental element-- be it dietary or otherwise.-- Mark Bornfeld DDS 17:25, 3 January 2006 (UTC)
Is the concept of death star is feasible?
Statement #1
"Alderaan might have been a very tiny planet, so it would have been very easy to destroy". There is a fairly narrow range of planet types which can support human life. A human-habitable planet must have sufficient gravity to have retained an atmosphere after its formation, so Alderaan simply could not have been an extremely small planet. Furthermore, the Death Star has been explicitly described to be capable of destroying any inhabited planet.
OK, but Alderan may have been a small, ARTIFICALLY created planet. So it could have been build using superdense material material at the core to give it enhanced gravity.
Statement #2
So if we can't use melting energy or vaporization energy, how do we determine the energy requirement to destroy a planet? The answer, in one word, is gravity. If you wish to destroy a planet, you must scatter its mass so quickly that the forces of gravity cannot reverse the expansion process. In other words, you must accelerate the planet's entire mass to escape velocity. Another way of saying this is that you must bring the planet's gravitational potential energy state up to zero. The concepts of gravititational potential energy and escape velocity are both discussed in the science page. Using those concepts, the energy requirement for blasting a planet apart can be calculated.
The science page alludes to, but I cannot find where it says explicitly, that objects at the center have lower escape velocity than those at the surface. This is because the outer surface of the planet has gravity and tends to attract that at the center, away from the center. So it takes less energy to drive away the material at the center, than at the surface.
Depends, do you mean using current known physics, or unknown physics? Is FTL travel possible? What about time travel? I think that yes, a Death Star is feasible, but not with current technology, as with many other things.
If you really want to kill everyone on a planet, a Death Star is an overblown (sic) and hideously bombastic way of doing so. It's far easier, and altogether more useful, to do what the aliens do in the novel Footfall. You just take your moderate sized spaceship out to the asteroid belt, grab a nice sized asteroid, and drag it back toward your target planet, engines at full blast all the way in. Turn aside at the last minute (or, better, use a robot spaceship for the whole deal) and let the asteroid whack into the target planet. The poor inhabitants suffer a giant tsunami and an impact winter. You can come back in a decade or so and find a nice uninhabited planet, with the climate returning to normal and all the life-sustaining lower organisms intact, but all the people who defied you killed in way the average interstellar-villain type will find particularly gratifying. -- Finlay McWalter | Talk 20:01, 3 January 2006 (UTC)

How does this work? Is the winter average atmospheric pressure normally higher or lower than the summer (where I live I would guess lower because its raining all the time, but in places with cold clear winters wouldn't the pressure be higher?) How would a higher pressure cause the release of more methane than usual? If it's a lower pressure, am I correct in assuming that it has to do with the pressure relative to the vapour pressure?.

Why is it that no photos seem to exist of the stars from orbit or space? I'm not talking about telescopic observations, but rather shots of what the starry plane look like, from the perspective of the human eye, while in space. For example, when the International Space Station or other spacecraft are photographed, space behind them always appears simply black. Is this how it appears to the eye or is this simply a problem of camera lenses? Furthermore, one would assume that, for example, from the dark side of the moon one would have a really spectacular view of the stars, but I have never seen any photographs from this perspective from the Apollo program. What's going on? Does the presence of the sun in space hinder the viewing of stars and turn space into a black blanket? Do the stars only come alive when you are orbiting about the dark side of the earth or the moon? Why are they never photographed?

If I have a solution with several components such as milk, water, and ammonia, how can I find the specific heat of the solution? I know the specific heat of the individual reactants but I don't know how to determine the specific heat of the overall solution. If anyone knows please list in J/g degrees celsius, Thanks! johnbog456
Yeah, that's right. Basically heat capacity (mass*sp. heat)is additive. So, (m1+m2)*C = m1*c1+m2*c2, where C is the sp. heat of the overall soln. deeptrivia ( talk) 05:51, 4 January 2006 (UTC)
I half don't expect and answer to this or I'm afraid I already know the answer. Can I crack the root password on a Linux box without root access?

Greetings:
I'm trying to find material relating to the concept of "Universal ID", which, in my case, is defined using the following scenario:
" A group of government officials and information managers at major corporations who point out that the proliferation of single-use identifying keys for individuals is causing major inefficiency, embarrassing and costly cases of mistaken identity, and considerable waste of time and money. They propose a single lifetime ID for every Canadian resident that would be used for everything from tax returns to grocery check-cashing cards."
And I have to argue along the lines of:
"a universal ID would lead to loss of privacy and essential freedoms, and would be open to considerable abuse."
I would highly appreciate any pointers to wikipedia entries, books, journal articles, web site materials pertaining to "universal ID" in the above sense.

Is the prediction by astrology correct? Is the basis of astrology is firm?
Also note that the "theory" behind astrology, if it can be called that, is based on the actions of Greek and Roman gods. If you don't believe in Roman gods, like Mars/Ares, you shouldn't believe that people born when Mars is visible will have the traits of that god (combative, for example). There is a basic incompatibility in believing in Christianity or any other modern religion and also believing in astrology.

Are there any viruses, bacteria, etc., that live in the cold weather? I know that the cold weather just weakens the immune system and makes the body more succeptible to infection, but i was just wondering whether or not there are any viruses that actually just live in the cold environments and are strong enough to infect people. Thanks! ----- Eryn
Short answer: yes. Long answer is more complicated. There are bacteria and viruses that thrive in extreme environments: freezing and boiling hot environments, but these rarely affect (or infect) humans. Shall we assume that you are only interested in bacteria and viruses that can cause human disease and the degree of cold is the winter temperature range away from the poles where most of us live (like down to 10 degrees below water freezing)? Moderate freezing cold will kill many bacteria and some viruses, but the main effect of cold on bacteria is just to slow down reproduction and activity (which is why refrigeration retards bacterial growth). Bacteria and viruses vary greatly in their abilities to survive outside a host but the temperature is less of a factor in this than availability of water and food and absence of harmful substances like soap or high osmolality or intense sunlight. Dehydration will kill most bacteria faster than cold will, but some viruses can survive dehydration and some can survive indefinitely being frozen. Some pathogenic bacteria require direct person-to-person contact (e.g., bacteria of gonorrhea or the AIDS virus), but others (e.g., the spores of tetanus) can survive in the environment for long periods of time in various forms. For example, there has been concern about whether smallpox or influenza viruses can remain infectious in graves. The most recent example was the investigation a few years ago of 1919 flu victims buried in the permafrost of extreme northern arctic islands for 80 years. Precautions were taken to avoid releasing potentially infectious material. That said, I don't know of any cases of smallpox or plague or influenza known to have been contracted from graves or crypts. Cold weather does have an effect on transmissibility of respiratory viruses by affecting human behavior and perhaps altering mucous membrane defenses. Complex topic. alteripse 13:45, 6 January 2006 (UTC)
Thanks... I know this is a complicated question. You were very helpful. However, are there any specific instances in which entering a cold environment would promote the spread and possible contraction of a virus or bacteria into a human body? And if so, what are they???? ----- Eryn
Ah, this sounds simple, so I'll wade in. This site [27] explains the #1 myth, ie. if you go outside 'You'll catch your death of cold!', which is usually uttered by an old lady in a Jane Austen novel. -- Zeizmic 18:05, 6 January 2006 (UTC)
Thanks for your input. I think i worded my second question poorly though. Are there any bacteria, viruses, etc., that live only in the cold weather and are then contrsacted by humans or animals? For example, a virus taht lives and thrives outdoors in cool temperatures and then infects the first host that it encounters. possibly this bacteria/virus stayes dormant until contact with a host is made.... (Maybe this has been answered already in a previous reply and i just dont see it.) But if there is such a virus/bacteria, a name or description would be most helpful. Thanks! ----- Eryn
THANK YOU SO MUCH!!!! This last piece of information is exactly what i was looking for. Thank you so much for everything. -----Eryn
Hi, I read in several places that the fundamental building block of the universe is information or events...I know how it sounds, but I haven't read it in new agey looney pages, I read it in like, news articles, and in some physics pages which I cannot remember,but I can't distinguish real science from far fetched claims...so, do you think this is true or somewhat true? because I am aware that the building blocks of matter are quarks and subatomic particles like gluons and stuff.
also, quite apart from that, here's this quote :We are now synergetically forced to conclude that all phenomena are metaphysical; wherefore, as many have long suspected — like it or not — 'life is but a dream.' - Buckminster Fuller. see?

Cosmic girl 16:21, 6 January 2006 (UTC)
cool, so you mean that, information theory implies that nothing outside or besides the universe is required for the universe to exist? I mean, nothing besides the information and computations of our universe?... if so, how can it know that? I mean, can't the universe be like a big videogame? it can seem the only thing for us, but we can never know that which lies outside the computer that contains it ... maybe we can only know the software... it sounds really crazy and hard to understand, but i think that the information theory has space for a videogame conception of reality, or a simulation for that matter, but I know nothing about physicists, so I need the expert's opinion. -- Cosmic girl 19:30, 6 January 2006 (UTC)
I really suck at math and physics, but I believe that if everything is quantizied ( I'm sure I spelled that wrong :S )if everything is, I think the universe is no diferent than a videogame... but then, if it is, we can't know much about philosphy since the physics of the real universe (the one outside) aren't known to us...and maybe are even irrational to our brain...but that would surely signify there is a trickster God ...or a kid out there, haha -- Cosmic girl 16:52, 7 January 2006 (UTC)
You should really check out interesting things like physical information and quantum entanglement.

There is a psychology database similar to Medline and I think it includes parapsychology research. It will be available through most college or university libraries. Ask a librarian for help. The best starting point is often a paper that you do have, because the librarian can see how it is catalogued in the database and can then help you look for older but similar papers. There are a couple of American universities that have supported "paranormal" research, usually in association with the psychology dept, often under the name of parapsychology. You could call one of those depts and ask a secretary if a faculty member would be willing to talk to you once for an "interview to help with a school science project" and you might get lucky enough to get a few minutes of time. If so, ask their opinion of the research in that area and ask for suggestions on how to most efficiently find published research on the topic. They may be able to suggest specific journals, search terms or even authors to look for. Good luck. alteripse 20:53, 6 January 2006 (UTC)

How close are mankind from inventing a source of perpetual energy?
Of course, there are many energy sources that will last for billions of years, so are as good as perpetual, like hydro, solar, tidal, wave, wind, and geothermal energy. And while each chunk of fuel for a nuclear reactor may only last a few years, there is enough nuclear fuel to power the world virtually forever. Renewable sources, like wood, are also good forever if properly managed. Only fossil fuels will be "used up" someday soon, perhaps decades or centuries, that's not certain. StuRat 20:40, 6 January 2006 (UTC)
It's a bit more abstract, but the questioner might like to read Conservation of energy which states that energy is never created or destroyed, but is a constant. However, the Second law of thermodynamics states that the energy of an isolated system, while constant, is in a constant process of equalling out, meaning that the contained energy becomes more and more difficult to obtain in a general sense. -- Quasipalm 20:52, 6 January 2006 (UTC)

Wow, you've really given this a lot of thought, I'm impressed. I still think the number of calculations necessary to search all of Google for all pictures of trees would take way too long to be practical for a search at present, but perhaps it would be good to have the technology ready and waiting for when such computing capacity comes along. Of course, just like voice recognition, I doubt if once you have the program optimized to find trees if it will be any good at finding, say, birds, until you alter the program significantly, then the same for every other object it needs to recognize.
I think some of the steps necessary for this to work might be valuable in and of themselves, however. I listed one above, another that interests me is "reverse pixelization". That is, I would like to be able to take a bitmap of a line and a circle, say, and create a vector representation of the geometric elements. One application would be to take a low res picture and generate a higher res pic of the same thing. Edge recognition is one aspect of any such program, that might be mentioned under machine vision.
Well, as I say, I'm quite skeptical that you will get the full program to work anytime soon, but still think it is valuable for it's side benefits. And, if you can write and sell such a program, I'm sure it would be worth millions! StuRat 06:14, 7 January 2006 (UTC)
Neural nets are (amoungst other, equivilent descriptions) a statistics object. It might be worth persuing them from that angle, particularly if you're looking for rigourus descriptions.

ancient indian hermit & philosophist bharadwaja concieved ideas about flyinh machines which could carry people.this was about 5000 yrs ago (supposition).many of his own designs as in the text,was later found to be in resonanace with,latest aviation theories.as science advances ,how his ideas can be dealt with,on grounds of modern engineering principles?
I keep coming across websites that are not what their name suggests they are, e.g. they might link to a competitor's website (like www.national-express.co.uk links to a rail site instead of a coach site), or all the useful-looking links from a fansite turn out to link to commercial sites or attempt to upload files to my computer. Is there a name for such sites? I am trying to remove them from Wikipedia but would like to know how to describe them.

Is there a limit to how many computers a router can handle? Should a standard 4-port router such as the Linksys BEFSR41 be enough to serve IP addresses to a network of 30 or more computers via various switches, hubs and wireless access points? If not, what kind of a router is needed? Thank you, Adam Konner 19:06, 7 January 2006 (UTC)
Jebums, that was fast. My router serves as a gateway between the LAN and the cable modem, and also as the network's DHCP server, hence the serving of IP addresses. -- Adam Konner 19:17, 7 January 2006 (UTC)
Here's why I wonder: When I asked the Comcast guy if the new service would be sufficient to support 30 computers, he said that would be fine, all I'd need is a router that can handle all those computers. I can't find anything in the router's documentation about it. Searching for answers on the internet, I found this webpage that says, "On an eight-port wireless router, you may only use a total of eight connections, not eight wireless and eight wired." However, now I've found another page that seems to contradict the first one.

There is a rumor going on on the internet that say that the PS3's GPU codenamed RSX developed by Sony and Nvidia is less powerful then Nvidia's upcoming GEFORCE 7800 GTX? Is this true? If it is true then that would mean that the PS3's graphics are going to be obselete compared to computers that would use the 7800GTX.
The "RSX" that the PS3 uses is basically a copy of the 7800GTX except the "RSX" may be a little faster. As with all consoles and the PS3 is no exception, every console is obsolete as soon as they are released because high end gaming computers catch up and eventually surpass console hardware technology in a couple of months.
I've read our articles on magnet and magnetism, which say that magnetic fields are caused by the motion of charges, but then add that electrons in atoms don't actually move. What electrons actually do in atoms, apparently, is (i) to sit around in orbitals and (ii) to possess a property called spin, but they neither orbit nor spin in the mechanical sense. How does this mysterious behaviour create a magnetic dipole? I'd like to add the answer to this question to our articles, even if it's just that "nobody knows". -- Heron 20:49, 7 January 2006 (UTC)
Thanks. I'll revisit the magnetism-related articles. There were some contradictory statements, about electrons moving/not moving, that I was unhappy with.

I am a tad confused about the concept of, what is described in our article on black holes as "narrow jets of particles at relativistic speeds." I was wondering how this works, because I was under the impression that the gravity in a black hole was strong enough such that no matter can escape its gravitational pull. So how is it possible that the black hole can "eject" particles outwards and away from it's über strong gravity? Thank you. - Akamad 03:42, 8 January 2006 (UTC)
Are Jews (the people group, not the religion) smarter as a race? Because there seems to be alot of famous Jewish people, for exanple 22% percebt of Nobel Prize winners are Jews. So, do the Jews have a genetic or ethnic advantage in mental intellengence?
Cultural advancement of a group should not be mistaken for genetic superiority, it is like mistaking the superiority of a software for the hardware in the computer machine. Even if we all had similar computer hardware, since the software loaded in our machines will be different, it will make our computers look different. You may use different OS for example (OS is more like religious groups - I use Linux, but I am not a Jew). Race and skin color are more like the screen saver we use etc., etc. The main thing that really matters is the RAM and processor-speed; it can scientifically be proven that all humans have roughly the same levels. In the case of humans this all the more reinforced by the fact that a particular process of the brain can be trained to acheive high levels efficiency.

If nothing can reach the speed of light, why can light or electrons reach it?
is breaking the sound barrier as easy as snapping your fingers? if you snap your fingers, is the resulting sound due to breaking the sound barrier, the subsequent impact, or simply the loss of force due to friction?
if you google "sound geocities barrier snap" the very first page offered claims that a boom does occur on a very small scale.
Given that light can be pulled inwards by gravity(by something as massive as a black hole), and that it has a reliable velocity, and that those are the only two characteristics necessary for something to move into orbit around a celestial body, it there light endlessly orbiting black holes? Is there a distance out from a black hole at which, if you weren't pulled apart by the gravity or something like that, you would see a ring of light all around you? Because that would be pretty cool. It'd be fun to imagine something so absolutely black(except radiation) being encased by a sphere of pure light. If so, would that be near the event horizon? One problem I've found with this is that black holes are constantly expanding, so the orbital distance would be increasing as well, meaning any light currently in perfect orbit would eventually get pulled in, but maybe that's not a problem. -- Black Carrot 06:52, 8 January 2006 (UTC)
In a typical software company (like Microsoft, Apple, Sun Microsystems, etc.), do the programmer(s) responsible for a security vulnerability (wrote the code that caused the vulnerability, that is) get punished or disciplined in some way? -- 61.94.149.59 07:28, 8 January 2006 (UTC)
I understand that light hits the sail and is reflected back off the sail. My question is how masslesss photons can exert any pressure on the sail. When I use F = ma to calculate the force, even if the acceleration is from the speed of light in one direction to the speed of light in the reverse direction, I still get a force of zero for a massless particle. What am I missing ?
There is a device with a similar function, a "fan" inside an evacuated glass container with one side of each blade painted black and the other white. The difference in reflectivity causes the fan to rotate when in the light. This might be a purer example of the effect I'm asking about, since solar sails will also catch particles in the solar wind which do have mass. StuRat 08:03, 8 January 2006 (UTC)
I've read that article, and it really didn't explain it, just gave a formula to find the strength:
I'm really looking for an intuitive explanation. I suppose if it involves quantum mechanics or something else inherently non-intuitive, I will just have to accept it without understanding it. StuRat 09:09, 8 January 2006 (UTC)
Photoelectric effect. It's not really the same context as a solar sail, but it ends up ejecting electrons (which bear mass) - so it is ultimately the same principle. F=ma is an incomplete formula: it is incompatible with quantum mechanics. I myself am searching for a better formula (I have a hunch that one exists) that will account for the force a photon exerts on a mass, but also compatible with classical mechanical situations. (ie. breaking down the "mass" into different components). Elle vécut heureusement toujours dorénavant ( Be eudaimonic!) 10:02, 8 January 2006 (UTC)
I'm just a lowly engineering science-type guy, but this just F=Ma with the solar particles, and perhaps radiation (the wave-particle thingie). Solar sails are a thing of the past, I think good old ion engines with nuclear power are way better! -- Zeizmic 17:10, 8 January 2006 (UTC)
The problem comes from thinking of rest mass as the real mass. The relativistic mass is the real mass in terms of actual behavior. But it varies according to the relative speed of the object so isn't as useful in terms of teaching students or of defining invariable qualities of particles, so rest mass gets called the real mass and the actual behavior of objects becomes more mysterious. But's its easier to teach and they aren't going to become physicists anyway... WAS 4.250 03:11, 14 January 2006 (UTC)

1) Bullets travel faster than sound, right? So why don't we experiance a sonic boom, something like two bangs one for the gunpowder and another shortly after for breaking the sound barrier?
2) Would there be a light barrier eg. in theory if an object of some sort exceeds the speed of light (although not possible) would there be some kind of explosion of light as it build up aroung the object, this is all merely theoretical.
3) Is 100% insulation of an object possible? eg. a means of an object forever retaining constant temperature? and on the other extreme is 100% heat conductivity possible?

Continuing along the lines of 'miscellaneous question 3' and 'Thinking pc' above (I've put myself in that mindset, so now I interpret everything in those terms :) ). Quantum theory follows rationality to its logical conclusions. We are born with a priori knowledge, which we use to understand the word around us. All animals and other forms of intelligence have this. We have however formalised those rules (at least we try to). That's called mathematics. Next we started to strictly apply those rules and we came up with all sorts of things that our non-formal minds could no longer follow. You could say we have harnessed our intuition to the point that it's no longer intuitive to us. Then again, the notion of gravity was rather counterintuitive when Newton came up with it (something that excerts a force without touching!?), but we're completely used to it now. So maybe one day everyone will take quantummechanics for granted? Which is not to say we'll fully understand it. After all, do we really understand gravity? We merely accept its existence.

Is it possible to construct a device capable of sending someone to any one of the infinite alternate realities or universes? I also have a possible explanation as to the different variations and types of realities and universes: I believe that there are several different "Prime" universes. We live in the Earth Prime universe, or, the universe that all the different alternate realities are based off. All the litirature, stories, history, video game storylines, movies, and TV shows also have a Prime universe that that goes along with each individual series. History willl have several variations, like, George Washington doing a direct attack on the british instead of sneaking up on them during that fateful night. And your favorite characters from games and movies have their own Prime universes with their own infinite number of alternate realities. They all combine into one HUGE and always expanding omniverse. Anyway, you probably get my point. So, could it be possible to make such a device? (p.s. sorry about the long-winded theory. I tend to ramble on sometimes. I also got swept up by the concept and how exciting it would be if my theory proves true.) 68.116.175.201 23:57, 9 January 2006 (UTC)
If someone in this world were to be 100% emulated in a TV show, then there would be a copy. As I said earlier about the universes and variations, the TV show would have it's own universe, and have infinite variations. you could have a variation of our universe where YOU (yes, you, Black Carrot) could be of the opposite gender*. As for the discontinuities, there are things in tv shows that are unexplained,and that is where Fanfictions or destiny come in. if there is a unique fanfiction about a book or game, it causes the events of the fanfic to be a real event in that universes Prime. If there are multiple fanfics of the same event in different retellings, they mesh into one rettelling of the event and become true in the Prime of that universe, while variation realities select one of thoes fanfics to be real. if no fanfics are made to explain plotholes, a random explanation happens in the Prime of that universe. The discontinuity could be explained by a fanfic about a change in personality of the character, amnesia, or the characters decision to do something that, ultimately, leads to the lack of continuity. Also, two more things:

Well, I was trying not to make my posts so long, and thats why I didn't talk about that in my last post. You see, I often think about whether or not were in a fictional world that originated in some book somebody wrote or a lame TV show. For all we know, we could be in the worst sitcom ever made and not know it, But I have proof we're in the Prime Universe. Each variation is caused by the creation of literature that would describe how the world would be if something that happened had occured differently, or never occured at all. If we weren't the prime universe, then there would only be EXTREMELY small changes in between universes. The thing about Variation Universes(VU) is that if the universe is created by a story that tells only about a certain event, then that certain event is the one most important thing in that universes history, while everything else ends up being misinterpreted in general. The Prime Universe was started at random by I-dont-know-what and has no single event being the most important, and all the events that happen in this universe either get lost in the shadow of history or become warped, misread, misinterpreted, and mistranslated over time*. While VU's are created starting with that event, with no history as to what happened before the event took place. (*by this I mean like 200-1500 years) 68.116.175.201 23:57, 9 January 2006 (UTC)

Is interferon still active after freezing?
Interferon is a protein hormone. Freezing sometimes changes the tertiary protein structure, and can reduce ability to bind to receptors. The amount of change depends on lots of factors, but is hard to predict without actual experiments on the specific protein in question. It is unlikely to lose all potency with a single episode of freezer temperature or outdoor winter freezing, and does not become "toxic" or harmful, it just has a reduced potency. The degree of degradation (percent of remaining activity) is difficult to predict and might range from as little as 5% reduction of potency to 90%. Sorry, can't be more precise. alteripse 23:36, 9 January 2006 (UTC)

When you burn any type of matter it goes through a process called pyrolysis which is essentially breaking down the matter at a molecular level through oxidation. What is fire? (a rapid oxidation process, which is a chemical reaction resulting in heat and light at varing intensities). So what actually happens when you burn a candle is, the flame of the burning wick melts and vaporizes the wax and you are actually burning the vapors from the wax .The wick simpily acts to increase the surface area to such an extent that even a very low rate of evaporation results in a sufficiently high local concentration of parafin molecules in the air to support combustion.

Whether lactation is, or ever could have been, such a characteristic is not discussed. The remainder of the entry, comprising an additional three sentences, contains a description of the measures so far taken to allievate the author's confusion and despair, and an urgent plea for help which can not be lightly ignored by those possessed of even a modicum of compassion and human feeling. In the name of ben4nips, I call for a poll! An immediate and widespread display of generosity for this poor soul, whose only wish is to know whether he is alone in this world, or if there is another who shares his/her fate. If you or anyone you know, here or elsewhere, now or elsewhen, on Wikipedia or off, is or knows of someone who owns a perfect set of four or more nipples, respond! Hark to this call! A curious public awaits.
One other thing: try to make sure you can substantiate your story if asked to. We don't want any "I have a cousin who has a friend whose sister's dog heard from their pet psychic that someone they saw on the street had four nipples poking from under her shirt."
The article in question: http://www.bbc.co.uk/dna/h2g2/brunel/A8291702 -- Black Carrot 00:40, 10 January 2006 (UTC)
An interesting question. I find it hard to imagine it not being hereditary. To clarify the above: I'd like to know how many people with four (or more) normal nipples there are within reach of this page, or in general, neither of which that page gets into. Another question: What's the most nipples anyone's ever had? -- Black Carrot 05:22, 10 January 2006 (UTC)
A third nipple? Given the symmetry of the human body I'd expect an even number. Also, 2% of women have this? Must be very small in most cases then (or haven't I been paying attention?). DirkvdM 08:51, 10 January 2006 (UTC)
I knew a girl that had 6. She only showed us the extra 4, and the top 2 were almost regular but with no areola, and the bottom 2 were pretty small with one of them being almost not noticeable, more like a birthmark. I don't recall if she said they were sensitive or not. The article describes that they can be nearly fully developed, so I would assume that would include innervation. - Taxman Talk 16:23, 11 January 2006 (UTC)
Does eating faster make you fatter???
A physiological reason is that incoming food stimulates release of incretins and other hormone signals that begin to signal satiety to the hypothalamus. If you eat fast, you put more food in before your brain decides you aren't so hungry anymore. alteripse 03:33, 10 January 2006 (UTC)
If you watched the UK Sky One Paul McKenna programme yesterday (which you may possibly have done to prompt this question) you'll notice he also discusses this. I've tried it, and eating slower does make you feel more full. Alteripse's explanation is perfect - you could describe there being a lag between you eating, and your stomach telling your brain you're feeling full. Eating more slowly allows time for you to feel full while still eating thus eating less instead of over-eating and then feeling bloated. You can find clips from the "Paul McKenna will make you thin" show at http://www.skyone.co.uk/mckenna -Benbread 20:36, 10 January 2006 (UTC)

My father-in-law has an idea to produce hydrogen by putting high voltage into a tank of water and bottling up the hydrogen as it comes out of the water.

Anyway, electrolysis like this is perfectly possible and practical; people do it all the time. (It's a standard demo in high-school chemistry classes, for example.) You don't actually need high voltages, either. (The amount of hydrogen you get is proportional to the current, so you're better off with lower voltages and higher currents.) But, you won't solve the energy crisis this way, because the energy you get by burning the hydrogen you generate won't be any greater than the energy you spent splitting it off in the first place.

We need to discover that enzyme that apparently generates hydrogen and oxygen from water in photosynthesis. I asked my biology teacher what it was, and I'm surprised we haven't discovered it yet.

HI I'm doing a project on DNA at secondary school level (year 10) but first of all need to un derstand the basics, in terms of discovery, in a simple way. Who actually discovered DNA in terms of the helix model, because I always get a variety of names. Was it Rosalind Franklin, or James Watson and Francis Crick? I would be at this stage very grateful of any information received! Thanks.
A question for the thermodynamicists out there. I get the impression that it is probably useful to classify various energy sources as being "high grade" versus "low grade" or something in between, depending on how generally useful they are. For example, an energy source that manifests itself as heat with a temperature just a few degrees above ambient is "low grade"; you can use it to warm yourself up, but not much else. On the other hand, electricity is extremely "high grade"; you can do almost anything with it. (Mechanical energy, such as produced by a motor, is somewhere in between.)
Mixed up with my notion of "high grade" is an element of controllability; we seem to place a (to my mind) ridiculously high premium on the easy controllability of energy. For example, in a diesel-electric locomotive, diesel fuel is burned in a diesel engine to produce rotary motion... which turns a generator which generates electricity which is used to run motors to develop rotary motion again. This twice-around-the-barn conversion pathway comes at a pretty steep cost in efficiency, as opposed to having the diesel engines turn the wheels directly, but the compensating advantage is that the electric motors can be very finely and gradually controlled, whereas a pure-diesel locomotive would require some kind of high-power transmission, and those are notoriously difficult to build.
The tradeoffs can also be seen in home heating. If you heat your house with electricity, it's seemingly 100% efficient: any electricity which isn't converted by your electric heater into heat to heat your house with is lost as waste heat which... also heats your house. But of course it's not 100% efficient if you go back and look at the fuel that was (typically) burned in order to generate the electricity in the first place. If you had used the same amount of fuel to heat your house with directly (i.e. by burning it in your own furnace) it would certainly be much cheaper (and probably also more efficient). Heating your house with "high-grade" electric energy is overkill; heating is one of the few things you can usually get away with using the lowest grades of energy for.
Anyway, all of this is by way of prelude to my question, which is: what terms do real thermodynamicists use to talk about these notions which I've informally and unscientifically labeled "low grade", "high grade", and "controllable"?
Steve Summit ( talk) 18:13, 10 January 2006 (UTC)
I like the term Energy density (a rather undeveloped article). High-grade energy is the same as high-density energy. Low-grade or low-density energy requires a large amount of space, such as wind power, or trying to extract waste heat. -- 192.75.48.150 12:52, 11 January 2006 (UTC)

I realize that I have no scientific standing to ask a question about the article on the Gaia hypothesis, although I took graduate courses in geology in the early 80's, and in early 1979 took one of the good, early courses on "Ecoscience." I simply do not understand the language usage in one very specific case at the end of the article. It seems to me that the discpline of ecoscience of around 1980 had already developed a better and also accepted usage for one specific case which I describe below, in terms of a specific, just barely possible modification of one phrase at the bottom of the article on Gaia:
At the bottom of the article, there is an abbreviated section titled: "Gaia hypothesis in ecology." Here it is stated that "most ecologists agree to assimilate the biosphere to a super ecosystem...." Could this simply be a minor carelessness at the end of a very wonderful article? Let me voice my doubt by asking a question about the use of the phrase "super ecosystem." In what way does the expression "super ecosystem" differ in its meaning from the old "ecosphere" of around 1980? The "super ecosystem" as used describes the Earth at a planetary scale, such as is involved in the simpler description of "ecosphere."
Thank you for looking into this. -- Eorth57 21:25, 10 January 2006 (UTC)
So I'm a recent college graduate, I should be getting my Bachelor Science degree in Computer Science in a few weeks after my university finishes processing all my records and stuff.
One of the things I never, ever, ever got the chance to learn was writing compilers, or at least interpreters (it's probably easier to learn interpreters first before attempting to write a compiler for any given language, yes?). Sure, I did write a simple calculator program that allowed for parenthetical notation using a stack which gave me a very basic and simple idea of how parsers work, but that hardly was enough experience to dive in and attempt writing an interpreter.
Local bookstores aren't exactly filled to the brim with books on advanced topics like these in their Computing aisles, so browsing and leafing through the pages before I buy isn't necessarily an option for me. I notice there's many books on Amazon.com, but considering how freakishly expensive they all are, I'd rather not empty a paycheck on a ton of books about writing compilers or interpreters. Can someone with experience in this subject recommend one or two -definitive- books that cover most of what I need to know? I've read customer reviews on most of what I saw, and there seems to be serious pros and cons to all of these sources. A frequent complaint about "the dragon book" is that it doesn't cover object-oriented languages, but I'm not interested in that anyway. And some people say it's easy to understand, other people say it's convoluted and mazey in its explanations. And would buying a book on -compilers- be overkill if all I want to do is dabble in writing my own -interpreter- (I have, specificially, LISP or something LISP-ish in mind) from scratch?
Sorry if this question is worded in a rather roundabout manner. I just want to teach myself the general science and fundamental theories of writing interpreters and/or compilers so I have something that's actually substantial on my résumé, which is currently populated by tumbleweed, dust, and a couple of lazy cows, but I'm not about to spend well over $500 on a whole bunch of books on this subject, of which only one or two might actually be easy to comprehend. -- I am not good at running 21:57, 10 January 2006 (UTC)

Hello, and I hope you can shed some light on this. Closing the lid and walking away is supposed to be supported on my Dell Inspiron 5100 (Win XP). Opening the lid is then supposed to restore whatever was running. But consistently when I do so and come back a couple of hours later, the screen is blue.

Of course I can always reboot and use my computer without problems if I don't close the case and go away with programs running. I've done so 6-8 times. So maybe I should just let it be.

I was reading somewhere recently that the long-distance communication common in sci-fi books/movies/etc. (i.e., communication between people/spacecraft at different planets, different stars, different galaxies) would be impossible because the limit to the speed of light means that communication between even Earth and Mars would have a minutes-long delay, and across stars would have a years-long delay. But isn't there something in quantum physics where making one particle spin one way makes another particle spin the other way at the exact same time, no matter how far away the particles are? Wouldn't it be possible to communicate via these spins (maybe one spin=0 and the other =1 and then read it via computer)? Zafiroblue05 20:23, 11 January 2006 (UTC)

What are the health risks and benefits of (dry) snuff? Mysteriousinventors 05:53, 12 January 2006 (UTC)
Cancer risk: Inconclusive. Studies have documented cancer in African users of snuff adulterated with charred aloe stems. Another report exists of a man contracting squamous cell carcinoma from placing snuff (presumably nasal snuff, as opposed to oral moist snuff, but this isn't specified) in his ear, an area that also receives UV radiation from the sun. Another report found a fourfold risk or oral cancer in persons using American dry snuff on the gums. There are currently no reports linking nasal cancer to European nasal snuff (with or without confounders like smoking, industrial chemical exposures, etc.), but this may be more a reflection on the paucity of studies examining nasal snuff than it may be on snuff's possible risks.

It's not exactly a health benefit, but the miniscule byproducts of dry snuff (mainly from sneezing) are socially acceptable—unlike smoke and large amounts of sticky, foul-smelling saliva—so one can use it almost anywhere.

Permeability is measured in Darcies (D)or milliDarcies, based upon the work of Henry Darcy (circa 1856), but who in more modern times, re-wrote the equation in the familar form and coined the descriptive name (Darcy) of the unit? I have serched the net to no avail so far??

Also note that Tesla wanted to broadcast power, as opposed to just a signal. It is possible to broadcast large amounts of power, but would be very dangerous and the ability of anyone to tap into the power for free would also make it impracticle. That said, if the power needs for a cellphone can be reduced to an extremely low level, they may not be so worried about the danger and costs, which would be greatly reduced to match.

Hello! If the human genome was 99% mapped to 99.99% accuracy back in 2000, why do we still have nothing remotely close to a cure for purely genetic diseases? As I see it, there is still no idea where most genetic diseases come from, let alone a cure. What was accomplished and announced with great fanfare back in 2000, if we have not seen any significant benefits 6 years later? I thought that having a complete understanding of DNA would enable us to totally eliminate thousands of diseases, from Down Syndrome to oily skin. What am I missing?

Hello, I have a question about liquid soap that has been driving my family crazy! My liquid soap dispenser rests on my sink ledge in both of my bathrooms. However, in one of my bathrooms (the larger of the two) the soap becomes very watery, loosing almost all soap consistancy. It can still lather, yet its like pumping water out of the dispenser. We had some theory about people watering down our soap for some reason, but that is very unlikely. When we fill up the dispenser, the soap is always of regular thickness. After a few days is when it starts to go liquidy. I've recently put tin foil around the dispenser and the problem hasn't occured in a while. The soap brand is Dial. I'd appreciate any insight into this strange phenomenon of soap. M@$+@ Ju 23:18, 12 January 2006 (UTC)

my friends and i were having a discusion on wheather or not a United States milatary fighter jet has the structural intergrety and power (propulsion) to make it to outer space. Now we do understand that a fighter yet is not desinged for exiting the earth's atmosphere. let's pertend that we have to put that jet in space. what does it take. i believe a fighter jet does have the structural intergrety to make it and it does have the propulsion as welll. now i believe that because of the lack of oxygen in outer space, the yet would not make it. now i believe (i may be wrong) that if we attached some type of oxygen tanks to the jet so it can be used to burn the fuel, the jet then could make it to outer space. Main question is can the jet itself without any extra addings to the structure of the jet, can it make it then ( remember we are able to only add some type of gas tank to help burn the fuel). the other question is does the earth's atmophere cause the jet to burn on the way out to space.

The patella is cartilaginous in early infancy. The first appearance of bone occurs at 32 to 76 months in boys, and 20 to 40 months in girls.

The stars are big balls of gases (helium, I guess). Being so, why does it take billions of years to burn (fusion) all that gas, thus making a star extinct, in stead of burning it all at once, as when we light a fire next to a balloon full of inflamable gas, making it explode? Thanks for any help.-- 201.28.77.123 01:50, 14 January 2006 (UTC)
Gravity causes matter (mostly hydrogen) from space to gather together. Momentum causes stuff to circle each other rather than all go staight away into one big clump. Over time clumps get bigger due to gravity. Eventually some clumps of mater get big enough that the pressure at the center causes fusion. The fusion creates energy that counteracts the gravity. The size of the star is all about the balancing act between the force of gravity and the force of the energy created by the fusion. More matter in the star produced more gravity causing more fusion creating more energy thus balancing the more mass. When the balancing act is disrupted by something the star can colapse or explode.

In your website, you talked about scientific evidence for evolution.But then, how come I've heard Christians and creationists claim that there are scientific evidences against it? I'm confused! How can there both be evidence for evolution(or any other theory) and against it?
Exactly what are these claimed-to-be evidences against evolution and are they really evidences against it? Can you please make an article about these claims of scientific evidence against evolution?
One can find evidence for and against almost anything. For example the Flat Earth Society collected all kinds of peculiar and isolated "facts" they would claim as evidence against a round earth. Likewise if your a priori commitment is against evolution you can find some "evidence" against it. The latest fashionable evidence (now termed irreducible complexity) is a re-tread of William Paley's 19th century observation that the eye is really complicated and he just couldn't imagine any stepwise development of the eye; likewise Michael Behe just can't imagine that various complex molecular systems could have developed in steps. The other major "evidence" cited against evolution is that we don't have fossils of many intermediate forms of animal that would seem to have been in a lineage (we have many but not all). We have many articles on the controversy (see all the articles linked to evolution, creationism, and intelligent design). Despite these pieces of evidence, unless you have a prior faith commitment to the late 19th creationist scenario, the more you learn about biology the more it becomes overwhelmingly obvious that evolution in some form has certainly been occurring for millions of years, that all forms of life on this planet share a genetic ancestry, and that there a zillion pieces of evidence supporting it for every one that someone claims opposes it. alteripse 04:29, 14 January 2006 (UTC)

After drinking quite a bit, I find I need to urinate. What's strange is that shortly thereafter, I get this constant urge to urinate, no matter how often I go to the bathroom.

The frequent urge to urinate can also be a sign of some type of urinary tract obstruction-- for example, Benign prostatic hyperplasia, prostatitis, neurogenic bladder, or other functional derangement of the urethral sphincter. This often manifests as urinary retention, or the sense that the bladder retains residual urine after urination.-- Mark Bornfeld DDS 15:30, 14 January 2006 (UTC)

can homosexuals be treated through psychiatry???
Ask yourself if your heterosexuality can be "cured" thru psychiatry ... then you will know how homosexuals feel when they hear such a suggestion. StuRat 09:58, 14 January 2006 (UTC) i am a homosexual.that is why i am asking this question. Homosexuality is not considered a disorder, and most people would be offended by the suggestion. There are places where far-right religious groups attempt to do this, but it basically amounts to psychological torture. The Nazis spearheaded similar efforts. The result is usually the creation real psychological disorder (for obvious reasons) or at least personal trauma of some kind, not a change in the person's sexual orientation. -- Tothebarricades 11:53, 14 January 2006 (UTC)
The answers are certainly politically correct, but not entirely factually correct. There are people with homosexual orientation who have sought treatment to change it and there are doctors who have sought to help them. Treatments in recent decades in Western society have been voluntary not involuntary and have not involved anything that would commonly be considered "torture" (i.e., no involuntary unpleasantness to the body). The success rates for these treatments do not seem to be large and "relapse" (for lack of a better word) is reportedly common. The arguments above that (1) homosexuality is not a disease, (2) one should not attempt to change this orientation for oneself, and (3) that it would be unethical to attempt to help someone change his/her orientation reflect a reaction to historical social mistreatment of people with homosexual orientation, are political attitudes which should not be presented as "facts", and are in logical contradiction to the general social POV that humans shuould be able to own and develop their own sense of sexuality found throughout Wikipedia and educated western society. This is exactly what political correctness is: socially enforced maintenance of a single political viewpoint on an issue for which more general ethical principles would allow a different or more than one opinion. Those who feel compelled to rebut, please address what is said here rather than supplying me with opinions I do not hold. alteripse 14:42, 14 January 2006 (UTC)
As a person who does not discriminate by gender, I take great exception to Alteripse's implication that "homosexuality is not a disease" is a political stance. There is far more evidence that homosexuality is a natural phenomenon than a disease/disorder. To "wait for findings", as it were, would be like questioning the holocaust because you've never visited Germany. It has far reaching social, not political, consequences.

I was intrigued by the previous post, which brought about a certain old thought of mine. If we could go faster than the speed of light into space, would we be able to "pass" the light from a historical situation and see it, such as we see stars as they were a long time ago? How would it look if we were looking back? Let's say we were going at cx2 with our backs outward. Would it just look like rewinding a tape? is this possible?

My girlfriend has an old Windows 2000 laptop with no wireless capability. I have a wireless card (PEAK Wireless; IEEE802.11b CardBus PC Card). However, her laptop can't find a driver for it. I've searched everywhere online for 'Peak wireless drivers', but can't find anything. Is there any other way of getting her computer to recognize the card, or a better online driver repository? My computer, which I assume has the driver, is busted, so that's out.

But in the interests of trying to be helpful, you might try starting in safe mode to see if you encounter the same errors. If not it may be the result of some program running in the background while you are in normal mode. If I remember correctly, Windows 98 has a thing called MSConfig that allows you to remove items from your start up sequence without having to actually open regedit. I would suggest removing everything from start up and then seeing if your system is more stable. If you have to run Windows you should probably upgrade to Windows 2000 if not Windows XP. They aren't all that wonderful, but compared to Windows 98 they are more stable and reliable.-- ◀Puck talk▶ 20:19, 15 January 2006 (UTC)
It can be anything, including bad CPU fan, bad memory, bad power supply, a large number of other potential hardware problems, and a broken Windows installation, which can be caused by normal cruft acumulation, a virus, or spyware. I'd recommend running a memory checker (like memtest86+), an antivirus, a spyware checker, and seeing how well it runs a CD-based Linux distribution such as Knoppix.

Are there any proofs or signs about wheather we humans as a species have evolved over the period of the recorded history? around 6BC-present day.
Recorded history goes back a bit further than that-- maybe back to 2000-3000 BC depending on your criteria. I can think of at least some indirect evidence for at least one evolutionary change. I think there have been changes in the population frequency of genes conferring resistance to certain widespread diseases during that time. I suspect there are others but don't know any others off the top of my head. alteripse 21:24, 15 January 2006 (UTC)
I also have to disagree with Kainaw. There is no evidence that the genetic height potential of humans has changed in recorded history.

Many drugs such as atropine and digoxin are isolated from plants. Why are these drugs regulated by the FDA and St John's wort or saw palmetto are not?
If you were cultivating them for profit, they possibly might. I don't think it regulates wildlife. Also regulating the processing (ie. turning the plants into the drugs) is more enforcable than regulating the plants themselves. Elle vécut heureuse à jamais ( Be eudaimonic!) 23:58, 15 January 2006 (UTC)
The answer is straightforward and involves the legal difference between
drugs and
dietary supplements. A drug makes a claim of therapeutic efficacy and is subject to the requirements of the
FDA for proof of safety and efficacy. A dietary supplement is subject to (relatively) much lower standards of purity and truthful labeling, and cannot make claims of therapeutic efficacy. A manufacturer who wants to market a substance can decide which type of marketing is likely to be most profitable. This depends on many factors, such as the obtainability of
patent protection and the likelihood that a demonstration of therapeutic efficacy would increase the sales and allow a higher price. Typically the manufacturer will opt for dietary supplement status if the substance is not patentable (like a raw plant extract) or he has no confidence that efficacy will be demonstrable by affordable clinical trials. Digoxin is actually a molecule copied from the active ingredient in
foxglove but is not identical to the old
digitalis preparations. I think
atropine is the manufactured active ingredient of
belladonna, but the pharmaceutical product has not been extracted from plants for many decades. I think there was a
chemotherapy agent (
taxol) that was actually extracted from plants a decade or so ago, but that is becoming less and less common.
Note the definitions have nothing to do with "natural" versus synthetic, or purified from plants versus invented, as there are plenty of examples of prescription drugs obtained from living sources and plenty of examples of dietary supplements that are synthesized in factories (e.g., most vitamins). A couple of excellent examples that show that the distinction has nothing to do with the biological nature or properties of the substances are the pairs of melatonin and pitressin, and dehydroepiandrosterone and hydrocortisone. The first pair are small protein hormones, secreted by the pineal gland and posterior pituitary gland respectively. The second pair are steroid hormones produced by the adrenal glands. All four have therapeutic uses. The first item of each pair is classified and marketed as a dietary supplement while the second of each pair is a drug.
Obviously many manufacturers market their dietary supplements with hype that skates as close to the edge of the law as possible, implying that their product will fix whatever ails you while including a little message that "this product is not intended for the treatment of any disease". alteripse 00:48, 16 January 2006 (UTC)
Hi wikiguys. I thought this was going to be a question-posting page but it's headed "comment". It's a question!
I've read both the "Y chromosome" article and the "genetic genealogy" article, and they didn't answer the question I was pondering about. I know we males get our Y from our dads and pass it to our sons (with a little bit of crossing-over at the tip during meiosis?), and I gather there are some variations in the Y but it mutates slowly enough so that, eg, one should be able to identify all of Tom Jefferson's male descendants (or perhaps they could be descendants of his brothers or cousins?). But *how* slowly does it mutate (on average of course)? How big a group of us would there most likely be with exactly the same set of base-pairs on the Y as I have - back to the great-to-the-nth-grandfather and out to the nth cousins, where n is what (or in what range)?
I'd quite like a personal answer to this, but the main reason I'm asking is so a bit more detail could be put into the exising entries. I find them interesting but provokingly vague at the moment.

This is an area of much research and some controversy. Many of the commercial genetic genealogy sites such as this one [68] assume a typical mutation rate estimate for each marker gene Y chromosome of about 1 in 500 generations (or 0.2%. On the other hand, cutting edge research on microsatellite mutation rates is producing different answers. See [69] for a more complicated and current discussion of the variation rates. These authors describe nearly a 10-fold difference in the rates produced by different estimates, suggesting that the results from some of the commercial public market labs are using some estimates that may need to be revised. alteripse 02:29, 16 January 2006 (UTC)
Thanks guys - all I wanted to know and possibly more. [Alteripse, do you spend all your time answering queries on this page?] I was really interested in an answer at an order-of-magnitude level, so regardless of doubts about whether the answer is 100 or 500 generations, it's clearly more than 10 or 20 (so if every male sharing the same Y had the same surname, there'd be less surnames than there are, cos surnames only go back 15-20 generations I guess). And Nunh-huh, yes, the query was inspired by watching a doco on Jefferson and Sally Hemings. I gather that some of Hemings's descendants who thought they were Jeffersons had their suspicion confirmed (as much as it can be - they could be descended from TJ's 3rd cousin if he was lurking around Montecello), while others found out they were clearly not descended from him?

Would a digital SLR camera, with a bigger diameter lens than, say, my little cannon elph digital camera be able to take better indoor pictures without a flash? In other words, if I try and take pictures inside without a flash (even in a well lit room) they are either blurry (too long an exposure) or very grainy (larger "ISO"). My question is, would a bigger lens be able to gather more light in a briefer amount of time, and therefore allow me to be able to decrease the length of the exposure without having to resort to higher ISO's, or is the aperture set somewhere else and this has nothing to do with the diameter of the lens?

Can an individual who is allergic to Penicillin have an allergic reaction if they eat Gorgonzola or Blue Cheese? Thanks.
I think the point of the question is that (since penicillin was discovered because it was produced by a mold) whether the blue mold that is included in the cheeses might contain enough natural penicillin to activate an allergy. The answer is no. I hate to say that there has never been a reported case (always a hazardous claim, even though the case may not have accurately proven cause and effect) but I am certain that if cross-reaction to mold were a clearly demonstrated phenomenon, it would be included in the avoidance instructions allergists give when someone is allergic to penicillin. Penicillin allergy is relatively common and certain other rare cross-reactions are well known to most doctors. alteripse 13:21, 16 January 2006 (UTC)

I would assume it would be easier because adults are stronger and would be more likely able to generate the force needed to propel the bicycle to a stable speed. But that could vary for someone very out of shape. Now adults are generally more easily embarrassed and therefore less likely to accept help and maybe less persistent in trying again, so maybe it would take longer in the end.

Scientists think that maybe lots of people have had bird flu, but haven't shown major symptoms.
No-one apparently realises that if that were the case, bird flu is not nearly as strong as they're making out to be.
Anyway, the only cases covered by the media would be ones where the ill people died. And they probably had something wrong with them anyway, like immunological disorders or something. That may sound extremely cruel, but I have no idea how else to phrase it :P

-- helohe (talk) 20:27, 16 January 2006 (UTC)
The current risk is important, but so is the potential risk. If we only took preventative actions against things which have already killed millions of people, we would suffer from massive deaths every year from disease. Some apparent threats, like Mad Cow Disease, never materialized, probably due to the corrective actions we took, like stopping the practice of killing sick cows, grinding them up, and feeding them to healthy cows (in their grain). Other diseases which were not widespread at the time of the first warnings, like AIDS in the early 1980's, have grown to the point where they do kill millions every year. So, such warnings are not silly, but should be taken seriously. StuRat 15:48, 17 January 2006 (UTC)

I have a suspicion he does not have a nearby Barnes & Noble.

The "institutional price" for one of these can exceed a thousand dollars a year. He will need to contact the publishers directly for the journals he is interested in; the contact information is usually available at the publishers' websites. An alternative is that many American libraries are willing to ship duplicate journals to third world libraries, but you don't always get the latest issue when published.

Actually, I can think of several useful reasons for researching a correlation between salivary volume and demographic data-- for example, it could be compared with various epidemiologic data to gain insight into salivary function or the mechanism behind a particular disease-- tooth decay, for example. However, I am unaware of any studies dealing with salivary volume and ethnicity or nationality.-- Mark Bornfeld DDS 14:05, 18 January 2006 (UTC)

Is it possible the earthquake that created the tsunami of December 16, 2004 has had an effect on global warming? The NASA website has published the earth tilted on its axis by as much as 2 centimeters and the sphere of the earth was also flattened causing the revolution of the earth to slow down. Would this change global temperature? I have not seen or heard of any reference of the two being linked or related. (unknown author/time)
It takes an enormous amount of energy to shift the earth by 2 cm, but that's still so tiny as to be insignificant compared to the size of the earth. Night Gyr 08:25, 18 January 2006 (UTC)
The earth wobbles on its axis all the time ( Chandler wobble).

Do you have an estimation for "Total number of cell divisions in the history of life?" Thanks
Taking inspiration from the
Drake Equation, I have created the "
Johntex equation" in attempt to estimate how many cell divisions have occured since the origin of life on
Earth:
Variable | Description | Value | Source |
---|---|---|---|
EarthPop | Current world human population | 6,450,000,000 | http://en.wikipedia.org/wiki/World_population |
HBC | Cells in an average human body | 1E+14 | http://ask.yahoo.com/20020625.html |
HBCD | Number of cell divisions needed to make 1 x 10^14 cells | 7.03687E+13 | Math |
HBCR | Numer of times, on average, each cell in the human body replaced during life | 3 | My estimate |
PerBio | Percent humans comprise of the world's biomass | 1% | http://www.space.com/scienceastronomy/plant_food_040629.html |
Years | Years since the origin of life | 4E+12 | http://en.wikipedia.org/wiki/Timeline_of_life |
Turnover | Number of years needed for world's biomass to turn-over, on average | 20 | My estimate |
Conclusion | Total number of cell divisions= | 2.72E+47 | =EarthPop * HBC * HBCD * HBCR * PerBio * Years / Turnover |
The total of 2.72E+47 would be just for life on Earth.
If one wanted to also consider the number of cell divisions that have occured in extraterrestrial life, one could multiply by the number of worlds that support life using a modified version of the Drake Equation. To do this, one would ommitt the variables relating to the life forms developing an intelligent culture, for example:
If R=10, fp=0.5, ne=2, fl=1, and L=100,000,000, then the modified Drake equation would give 1E+09.
Multiplying 2.72E+47 by 1E+09, we get 2.72E+56 for the total number of cell divisions of all life anywhere in the Milky Way. By comparison, the total number of stars in the Milky Way is estimated to be something more than 2E+9. By these calculations, the number of cell divisions that have occured in the galaxy would be about 1.36E+47 times more than the number of stars in the galaxy.
I think these figures are probably accurate to within about 10 orders of magnitude. Johntex\ talk 22:25, 18 January 2006 (UTC)
That equation doesn't look quite right to me. For example, why would you multiply by 1% if you thought humans were 1% of the biomass on Earth ? You should multiply by 100 instead. Of course, this is still assuming humans' cellular reproduction rate is the same as the average of all life, which is a highly questionable assumption.
I would also think you would do best to ignore humans and concentrate on life forms which have been alive for much longer than us and which have cells that reproduce much faster than us, such as bacteria. They will account for far more of the cell divisions in the history of the world than humans will. StuRat 22:41, 19 January 2006 (UTC)

This isn't just limited to the wheels of a car - you can also see it in LPs, for instance. I believe it's due to an interference effect, which occurs because your eyes only have a limited "refresh rate" (ie they only pick up new information at a certain rate, approximately ten times a second IIRC). If the wheel has repeating radial markings (eg spokes), if it spins at a certain speed, your eyes think that each spoke has moved slightly backwards when in fact it's the previous spoke which has not quite reached the position of the next one in the time it takes your eyes to take in new information. So your eyes are telling you that the spokes are actually moving slowly backwards... — QuantumEleven | (talk) 14:26, 19 January 2006 (UTC)

In Britain everything uses 13-amp plugs except for electric shavers which for some reason use two pin plugs. Why is this, and why is it only for electric shavers? smurrayinch ester( User), ( Talk) 15:10, 19 January 2006 (UTC)
I think your missing the point, i thinks its more to do with having a different plug in the bathroom so you don't get tempted to put your plasma screen in there.
Our article BS 1363 gives some description and this article says that the standard BS 1363 is to be installed throughout (no bathroom exception). A point of confusion may be interchanging the words outlet (on the wall) and plug (on the device). The outlet requires that a third prong on the plug (device) be present and inserted into the outlet in order for the other two plug prongs to be allowed "in". Since double insulated devices (electric shavers, hair dryers, etc) don't really need this third "earth/ground" connection for safety, those devices may use a non-conducting (plastic) prong in order to open the outlet for the other two prongs on the device to be allowed in. Back to the original question, device manufacturers have devised some proprietary workarounds that permit their double insulated devices to be inserted while having only two prongs and I suspect that is what Smurrayinchester was referring to. hydnjo talk 19:47, 19 January 2006 (UTC)

great, I agree, but for example, what do you think about David Deutsch? I don't know if I missunderstood the article, but How can an infinite computation (software and information) be possible without a computer (hardware)to contain it? here is one quote of his: Think of all our knowledge-generating processes, our whole culture and civilization, and all the thought processes in the minds of every individual, and indeed the entire evolving biosphere as well, as being a gigantic computation. The whole thing is executing a self-motivated, self-generating computer program. More specifically it is, as I have mentioned, a virtual-reality program in the process of rendering, with ever-increasing accuracy, the whole of existence. I don't understand what he means since he is an atheist and that sounds a lot like abstract and uncomprehensible mysticism and absolutism to me. other way to put it would be the way he said it, but stressing that there's a reality outside that whole of existence he talks about, because that whole of existence mus be being computed somewhere otherwise it would be just God. I mean, how can a virtual reality be self generating? i think it can only be so from a 'pantheist' view...but not from a virtual reality view, since that requires an outside world I think.-- Cosmic girl 20:41, 19 January 2006 (UTC)

I was merely entertaining the thought that it would be rather cost effective to send a self-replicating robot with the ability to follow simple instructions and build structures as well as copies of itself to the polar caps of the moon using the materials it mines from beneath the surface. It also would probably be cost effective if they could build solar-panels but I have a feeling that you can't build that kind of stuff from raw materials on the moon! freshgavin TALK 04:39, 20 January 2006 (UTC)
I suppose a self-replicating robot is available today...provided it is supplied with two halfs of a robot and merely needs to plug the halfs togther.

A robot that could assemble another starting from mining the raw materials, smelting them, etc., might not be available for centuries. StuRat 05:55, 20 January 2006 (UTC)
If you have time, try reading Prey by Michael Crichton. In that, nanobots are created that can kill things, break them down, and turn them into swarms of nanobots that can continue the cycle.

The tooth enamel page states that tooth enamel is hydroxylapatite. The Hydroxylapatite article discusses how hydroxylapatite is sometimes used as a bone filling in some medical procedures. This begs the question (for me, anyway): Why isn't hydroxylapatite used as a dental filling? (I previously asked this question on the talk pages of dental filling and hydroxylapatite. Both articles would benefit from a mention of the answer, if anyone knows.) Regards - Tempshill 06:39, 20 January 2006 (UTC)
Actually, tooth enamel is predominantly composed of hydroxyapatite, with a minor amount of organic component. The reason it is not used as a restorative dental material is that it cannot be cast, pressed, or otherwise shaped into solid forms that can accurately fit the cavity of a tooth. It also cannot be placed and adapted into a cavity in a plastic state (as can, for example, dental amalgam).
It is unfortunate that hydroxyapatite cannot, at least with current technology, be used as a dental restorative material. Fillings made of this material would have many physical properties (strength, hardness, and coefficient of thermal expansion) that would make it ideal.
Hydroxyapatite (Calcitite) and other mineral bone analogues are used in bone grafting applications, but not primarily for their physical properties. It is more for their relatively high biocompatibility, and their ability to form a physical scaffold on which new bone can form and fill in. Unfortunately, there is no analogous process that occurs in teeth. When enamel is injured, it must be repaired with artificial materials-- it does not heal, as does bone.-- Mark Bornfeld DDS 19:12, 20 January 2006 (UTC)

Actually, pH regulation in human beings is understood pretty well. There are no major "unsolved mysteries" or "big questions" remaining. NS has a pH of 5 off the shelf, but is quickly and easily buffered by the human body as it is infused. Blue Platypus was trying to reason it out but was working with several wrong assumptions about volume of diffusion and buffering capacity of blood and body tissues. There are iv solutions designed to mitigate (or not exacerbate) acidosis (such as lactated Ringer's solution), but there are very few clinical situations where you could detect an advantage. Also note that there is a lot of quackery out there about how the body handles acids and acidic foods that is pure nonsense. alteripse 18:19, 22 January 2006 (UTC)

Hello, Would you tell me what type of portable laser could be used to cut through ice but not harm people and not be effected by metal. I'm looking for type and power level. I suppose solid state and a moderate power level would work. I'm picturing like a saw with the beam going between 2 points andcutting the ice as it moves through it. Thanks. Scott
Not sure if I have the terminology correct--tail spin--but where can I find more information about it? My understanding is that when a jet-based aircraft stays at the same horizontal position and spins about the vertical axis towards the ground, it's referred to as a tail spin. Last I heard, there was no direct known cause, and there were mysteries surrounding recovery from such a situation.

I am going to give some counter-arguments refuting the arguments many people have made against the theory of Parallel Universes:
First, I've heard that the theory of Parallel Universes isn't very scientific.But just because a particular belief,idea or guess isn't scientific doesn't mean it's not true, or it can't be true.Look at all those religions and religious beliefs in the world.Those beliefs which many of the religions in the world are based on or teach aren't very scientific, but that doesn't mean that they're not true!! I've heard some creationists say that the theory of Parallel Universes can not explain why the Universe has the conditions,physical laws and physical constants needed for life to exist, because there's no evidence to prove it.Actually, things are the other way round.The fact is, there is evidence to prove it is true because it explains very well why the Universes has the fine-tune conditions needed for life exist.After all, people have also said the theory of intelligent design is not true because of that sort of stuff.
Second, I've that the Multiverse hypothesis is not true because some scientists say that it's inevitable that the Universe turned out the way it is.Are they saying they know the reason why the Universe is the way it is, with all those physical laws,rules,principles and constants?First, isn't that pretty arrogant?Second, what is reason they know that the Universe is the way it is?If they don't know why the Universe has the laws and physical constants that it has, then they shouldn't make such an arrogant claim!!
Third, I've heard that the exist of many universes raises the question of whether virtual worlds generated by conputers and virtual reality should be counted among them.The existence of other universes means the existence of places and areas of space that you cannot reach no matter how far travel across the Universes.So the virtual worlds contains virtual objects, and are generated by computer or VR, are virtual or 'imaginary' Parallel Universes.
Fourth, I've heard that the Multiverse hypothesis violates Occam's Razor.By making such a theory, you then have to explain why different universes have different physical laws and constants.First, the Multiverse hypothesis is the simplest explanation!Intelligent design is far more complicated.Second, many theories have parts of them which unexplained when they were first made.For example, Newton's theory of gravity didn't explain why gravity exists.And even when the general theory of relativity explained it as a distortion of space time, that didn't explain why matter distorts spacetime.And when Darwin's theory of evoltuion was made, it at first didn't explain why different animals have differentlevels of survival ability in the first place or how living things originated in the first place.Third, as to what other universes might be like, that's very interesting.Who knows?One of them might even be like the world of Narnia in the story, the Chronicles of Narnia. Please tell the people who have been arguing against the multiverse hypothesis about my refutations or counter-arguments!!!!

I'm not looking for medical advice here, just someone to blame. (It'll probably end up being me.) What can cause an amalgam filling to crack? I'd love to think it was my dentist doing a sh*tty job, but one can only be so hopeful. Cernen Xanthine Katrena 08:07, 22 January 2006 (UTC)
Fillings crack for the same reason other things crack: the forces to which they are exposed exceed their compressive or tensile strength. This could indeed be partially the dentist's fault, if he selects a filling material that is inappropriate to the situation. For example, the use of dental amalgam in a setting where a full crown is more suitable might be considered unrealistically optimistic. However, this type of treatment compromise is made all the time, for the sake of economy. And as often is the case, a short-term economy eventually leads to extra expense if the selected material is not sufficiently durable.
Fillings also crack when they either become weakened or are subjected to abnormally high forces. For example:
So, either the patient, the doctor, or plain dumb luck may be responsible for structural failure of a filling.-- Mark Bornfeld DDS 15:01, 22 January 2006 (UTC)

I do tend to eat ice cubes, and it wouldn't surprise me if my dentai insurance wasn't going to cover a crown, so he did an amalgam filling to save me money (of course, it wound up costing me over three hundred dollars anyway...). At least now I know I can blame us both. Thanks again. Cernen Xanthine Katrena 10:57, 23 January 2006 (UTC)
I have the OEM version of Windows XP Pro installed on my current computer which I built myself. But I've just bought some new kit to build a replacement computer (new case, CPU, motherboard , VGA card and SATA hard-drives), because my current set-up is a bit tired. I plan to migrate everything from the old computer to the new one and re-use my existing version of Windows, but during the time of migration I expect that both computers will be in use until I retire the old set-up. I know there's a 45 day period where you don't have to activate Windows, but am I right in saying that I need to activate it in order to download the hotfixes etc? If I try to activate Windows on the new computer will it work or will it fail or will my old computer stop working because it think that I've got a pirated version? MrMcarthy

|<--F1-- | |<--F2-- | |
I have a question about the relationship between the linear and rotational analogs of
classical mechanics. In space, if a force (F1) is imparted on the end of a rod, the rod would gain both
translational kinetic energy and
rotational kinetic energy, and the force would be accounted for as both a translational force and a
torque. However, if an equal force (F2), is imparted on the
center of mass, there would only be a change in linear KE since there would be no torque. However, these two results seem to contradict each other, and to violate the
conservation of energy: despite the same force, the example of F1 gains additional (rotational) KE. Thus, the first time I saw the problem, I thought F1 should be divided into two components, one to calculate linear force, linear momentum, and linear KE; and the other to calculate torque, rotational momentum, and rotational KE. Yet I know this is not true from what I have learned(correction: see my comments below). How can one rationalize the extra energy due to the "double-accounting" of force in the example of F1? Does the force act over a greater distance? Or is there more energy lost to heat? --
JianLi 17:04, 22 January 2006 (UTC)
Assuming the object is in space, it would only rotate about it's center of mass if pushed on the end as in the case of F1. Thus, it would only have a torque in that case. StuRat 21:22, 22 January 2006 (UTC)
No, its center of mass will also have an acceleration equal to F1/m. So it will translate also. deeptrivia ( talk) 21:26, 22 January 2006 (UTC)
This is a tricky question. First of all, a force on the end of a ruler in the absence of friction will certainly result in both rotation and linear motion. The linear motion should be the same regardless of where on the object it's applied, so there does appear to be a paradox. I'm going to consult with some of my fellow physics grad students and get back to you on this later. -- SCZenz 00:59, 23 January 2006 (UTC)

Hi, this is the original poster. Thanks to everybody (especially Keenan Pepper, deeptrivia, and StuRat) for responding. I haven't read all your responses yet. However, I see some pretty heated arguments, and I just wanted to clarify what I know for sure (as these answers are from the 1998 Advanced Placement Physics C Test (mechanics section, second free-response)
The reason there is so much debate over this, I think, is that it's hard to imagine what it is like in space since we draw heavily upon our experience on earth, where friction and gravity are big factors. That's why the ruler example that StuRat cited is not an accurate simulation of F1. Instead, try dropping a pen above a desk, and, as it is falling, hitting its end with with your finger in a motion parallel to the plane of the table. That way, friction would not be a factor, and also, gravity would be acting perpendicular to the force you impart, so it wouldn't affect it. As you can see, it gains both translational motion and rotation. -- JianLi 03:34, 24 January 2006 (UTC)
(m)<--v--(m) | |<--v--(m) | (m)
FYI, I looked at the original AP question, and it does not mention force at all, as it is a conservation of momentum problem involving collisions and velocity, so what I said in my original post, about what was "true," is not necessarily right (the amended diagram is above). That said, the previous two points that I numbered and bolded still apply. In this case, both collisions gain equal linear momentum/KE, and the upper case also gains an angular momentum/KE The AP problem is: there is a massless rod of length "l" with spheres of clay on the ends (each with mass "m") kinda like a barbell. Another sphere of clay with mass "m" and velocity "v" hits the construction perpendicularly and sticks. In the first example, it hits it in its center of mass, and the second example it hits at its end (striking one of the other spheres). Remember, in both examples the moving mass sticks to the barbell. Obviously, the two systems have the same initial KE. However the rod in the second example gains rotational KE as well as the translational KE that the first rod also gains. Why? This is because in both cases, KE was lost to heat, etc. due to it being an inelastic collision (since the clay stuck), and more KE was lost in the first collision than in the second, which explains why the first collision had enough energy to have rotational KE too. Like I said, I'm not sure how this relates to Force, as this problem only mentions velocity, and I think it could be any quantity of force, depending on how much time the collision took () -- JianLi 04:12, 24 January 2006 (UTC)
Ok, with the new clay ball model there would be some changes. In addition to delivering a certain amount of energy, as the force would, the clay balls will also increase the mass. In the case where the clay ball hits at the other clay ball on the end, the rod will rotate about the NEW center of gravity, taking the new ball's mass into account. Since it doesn't hit exactly at the end, but rather at 1/2 the end ball's diameter from the end, some linear motion will also be imparted. StuRat 19:39, 24 January 2006 (UTC)

Can the resolution of the human eye be (roughly) described in megapixels the way digital camera resolution is expressed?
Digital cameras (and conventional ones too) mimic the retina using color sensitive receptors for red, green (x2), or blue on a CCD, which is much bigger than the retina. Each receptor functions as both a rod (since each one captures luminosity, regardless of color) and cones (specific to its named color only) at the same time. The receptors send this information to a CPU, which either compresses the info (like JPG) and saves it or just saves it (like RAW). A 3.1 mega pixel camera has 3.1 million red, green (x2), or blue receptors.
My biology text book says, “Input from about 125 million rods and cones synapses on bipolar cells, which send the signals to just one million ganglion cells.” Does that mean that the retina (our body's CCD) has a resolution of 125 mega pixels which is then compressed to a 1 mega pixel image sent through the ganglion cells?
For a digital camera to capture an image as crisp as the human eye can capture, would it need to be 125 mega pixels per retina sized area of its CCD?
Of course, we would need a matching printer, right? What if we were using our fictitious camera as a bionic eye and plugging it directly into the optic nerve? Would we only need one mega pixel per retina sized area on our CCD or would we need the 125 mega pixel with a CPU to compress the info down to 1 mega pixel? -- TheLimbicOne( talk) 18:24, 22 January 2006 (UTC)

Note that just about any theory has evidence for and against it, you must go with the majority of evidence to determine if the theory is reasonable or not. For example, the presence of pyramids in both Egypt and South America could be taken as "evidence" that the ancient Egyptians colonized the Americas. However, there is far more evidence that they didn't (different style pyramids, different time frames, low technology level of Egyptian sailing vessels, different genetic profiles of the individuals, different skeletal features, lack of historical accounts, etc.). StuRat 23:18, 22 January 2006 (UTC)
No scientific theory is perfect; every nontrivial scientific theory has unexplained aspects and unanswered questions. Science is always trying to refine its theories and answer new questions that come up. If there are currently a few unanswered questions or unrebutted critiques of evolution, this does not mean that evolution is "troubled" or "in doubt" as a theory. Quite the contrary: it means it's a healthy, vibrant theory. (It would be extremely unusual if a theory as complex as evolution did not have a few unanswered questions or unrebutted critiques at any given point in time.)
What's important to realize is that most of the allegedly "controversial" aspects of evolution which are bandied about like so many brickbats by evolution's latter-day critics are not, in fact, brand-new hitherto-unasked impossibly hard questions which scientists can't answer. They are or might once have been good questions, but they're questions which were asked and answered decades or centuries ago. Our current understanding of evolutionary theory does not quail before these questions: it embraces them; it's happy to answer them; it owes its current form to the fact that it has successfully addressed and answered them.
In particular, the notion that life is "too complex" to have arisen by chance, and "must obviously" be the work of an intelligent designer, is a very, very old one. It was most famously expressed by William Paley over two hundred years ago, in 1802, but it goes back at least to Cicero in ancient Rome. If you accost a modern evolutionary biologist and suggest that life is "too complex" to have arisen by chance, he is not going to slap his forehead and say "You're right! I never thought of that! Our whole theory must be wrong!". Instead, he will explain (if you're patient and open-minded enough to listen) how the available genetic diversity and mutation rates and natural selection mechanisms are more than adequate to explain the current complexity of life as we know it, given the millions of years it's had to evolve. It's true that this is a surprising result, and that it contradicts intuition. Many scientific results are like that. But the evidence behind the theory and the math that ties it together are unshakable. Steve Summit ( talk) 03:57, 23 January 2006 (UTC)

If you add up all of the energy in the universe, converting all mass into energy, and then allow for the negative energy of gravitation, the result is zero!
"In the inflationary theory, matter, antimatter, and photons were produced by the energy of the false vacuum, which was released following the phase transition. All of these particles consist of positive energy. This energy, however, is exactly balanced by the negative gravitational energy of everything pulling on everything else. In other words, the total energy of the universe is zero!" [86]

If there is some one out there developing .NET applications for Windows CE, you could help me. I'm evaluating the possibilities to migrate from PLC control in an application (which I would rather keep to myself which one it is) to using computers instead - and I've already done successful test "concept" applications on Windows XP using .NET Framework version 2. However, if it is possible to use Windows instead / in combination with Windows XP that could mean a cheaper/better overall solution.
I'm wondering what kind of development platform is necessary on the development PC, to develop applications for Windows CE, including deploying them to a smaller number of devices with preinstalled Windows CE 4.2 and/or 5.0. I'm trying to understand by looking at microsoft.com, but it's hard to find the right stuff there as it is such a big website, there's loads of marketingspeak, and most of the actually useful info is for the old version of Visual Studio, 2003, and I'm using 2005 standard edition. Also note that I'm mostly interested in development of applications, but I would also have to be able to install them for it really being usable. :)
I would get devices with Windows CE preinstalled. Most of the tutorials mention a program named "Platform Builder", is that really necessary for application development only? Also many of the 2003 tutorials mention that there is a Windows CE emulator in Visual Studio 2005, but it seems to have been cut (there are PocketPC emulation included though). I am also missing the "CAB Build" option that is described in the VS 2003 tutorials... Basically, any feedback would be greatly appreciated! 62.119.184.141 13:16, 23 January 2006 (UTC)
HELP! i'm getting desperate. does anyone have a solution to this diagnosis.
i have had a ct, mri, abr, audiology, medication, antihistimines, with little success. all tests were negative. the sound has become so severe that it wakes me up at night and i have three distinct sound levels at the same time: hissing, ringing and bells. all sounds are different frequencies.
hearing aides for white noise did not help. tomos and panorex showed no symptomology,and i had never been exposed to loud noise so that rules out structural deviation.
so what do i do? i'm becoming very frustrated and agitated due to the constant noise.

Make sure you aren't taking any meds which contain aspirin, although your problems sound beyond those typically caused by that. Also check all the other meds you regularly take (including birth control) for any mention of tinnitus as a side effect. You might also want to look each up on the internet as it may still cause tinnitus and just not have it listed.
You didn't say whether it's in both ears or one. If just one, I would think that would indicate a problem with the ear itself or the immediate surroundings, such as a partially blocked eustachian tube. StuRat 16:05, 23 January 2006 (UTC)

Unfortunately, because the speeds are typically rounded to whole numbers in any of three different units, errors are often introduced when the table is copied.) --Anonymous, 04:40 UTC, January 24.
Two points, living in Tokyo I usually hear that hurricanes are considered stronger than typhoons, and though I haven't seen any figures I'd like to agree with that. There are usually close to 20 (named) typhoons in the typhoon season every year, and in fact quite a few of them hit Tokyo and Osaka (there is a fair chance that it could hit both cities). Tokyo was hit/grazed/passed over at least 2 times last season (fall, 2005) but it depends on what you mean by 'hit'.

I remember watching a documentary about the brain a while back that gave some information on an experiment (I believe by 2 amateur scientists) in sharing brainwaves (for the hell of it). I think the experiment was performed in the late 70s or 80s, and it was probably done with the pretext that it might be possible to enduce telepathy by amplifying brain patterns. I don't remember details of the experiment, other than the fact that it may have done with both subjects simultaneously or with recorded brain waves from one subject, and the results were simply that the brain couldn't handle/understand the input and the scientists were rather disturbed by the experience, so they gave up.

I'm sure everyone's seen a sci-fi movie with teleporters, like Star Trek or The Fly. My question is, if the machine is just reading all the cells in your body, and "beaming it" somewhere else (presumably they're destroying the body and transmitting the 'plans' to another body-producing machine), wouldn't this technically kill you? I mean, there would be another person with your thoughts, memories, that was identical, but your brain would actually be destroyed and your consciousness interrupted, so wouldn't you be dead?
I'm uncertain of the concepts behind teleportation and how to phrase my question, but it's a very interesting issue.
There is the issue of transporting the "soul"...at least for those who believe souls are attached to our bodies. Some religious people might very well argue that you have actually murdered the real person and created a souless duplicate. I suspect the anti-stem cell research people would be the ones who would move to have the process banned.
Also, some method would be needed to "jump start" the new copy. That is, the heart beat and other body rythms which had been interrupted would need to be restarted. Your thoughts would certainly be interrupted, perhaps like the shocks in electroshock therapy.
Note that the technology for a very crude transporter exists already. An object can be scanned with a CAT scan or other device, this info can be sent anywhere, then a new object can be created via rapid prototyping methods. The materials are limited to the plastic from the SLA process or the "wood" from the LOM process, and the resolution and size are also limited, and the full process will take hours, but the basic idea is there. All that is needed now are some refinements (which may take a few hundred years) before we can transport people.
Also note that only transporting from one "transporter station" to another would be possible. The idea of transporting to a place without a station to assemble the molecules seems impossible to me. And sending the actual molecules or energy to the new site seems similarly absurd. Only the information need be sent, so that molecules and atoms at the new site can then be assembled into the final object. StuRat 19:55, 24 January 2006 (UTC)
Also note that the technology to transport a retrovirus, some of which are basically just RNA, may exist in just a few years. We can scan DNA or RNA, transmit the info, and assemble DNA or RNA at the other end now. All that is needed is to increase the speed and accuracy to a point where an entire retrovirus can be produced reliably. Some consider a retrovirus to be alive, since they reproduce and evolved from more complex life forms. So, this will be quite a first step toward transporting living things. StuRat 20:37, 24 January 2006 (UTC)
One type of transporter might scan an object, disassemble it, transmit its structure to a remote device, and the remote device construct a new version of the object from its own supply of raw materials. Of course, if the initial device didn't destroy the object after scanning it, you would end up with a copy of the object as mentioned above. In contrast, transporters on Star Trek do not only transmit information. The matter itself is beamed (the "matter stream") to the remote location. This, of course, is why people and objects can be beamed to locations without a transporter, like the surface of a planet; if only information is being transmitted, a receiving device with a supply of raw material must be present. It is also why transporting is limited to a short range around the transmitter; if only information were being transmitted, then presumably one could transmit the information from relay to relay to reconstruct someone many light years away. — Knowledge Seeker দ 01:00, 25 January 2006 (UTC)
Matter Transmission existed in science fiction "literature" long before Hollywood popularized it and hijacked the terminology, confusing the ethical concepts.

Does anyone know of a mental disease or disorder which causes a person to intensely regret things which have happened in their life? Particularly things they have done? Captain Jackson 19:03, 24 January 2006 (UTC)
Hmmm. I've read your response about 6 times now and still find myself a bit baffled by it, I must admit.
The proof that you're asking for.
It was just an example to contrast with diagnosis. Red eye means red eye, not 'red eye v2', or 'suspected red eye', etc.
Simply that symptoms relative to diagnoses can be easily defined and classified (note: relative) whereas diseases, even when understood take on unpredictable characteristics.
the original statement was "No mental disease or disorder can be diagnosed merely from a single symptom". Your statement was "You are in no position to know ... if there are examples of mental diseases or disorders that have a single symptom". I'm sure what you meant to say here was "if it is possible to deduce diseases or disorders from a single symptom or not".
You have made many arguments, in fact I'm losing track. The basic structure of your argument is that it's impossible to deduce A from B when you lack the knowledge to do so, and I'm saying that equally it's impossible to assume that such a one to one correspondence is even POSSIBLE to exist because of the same reason. In fact, I'm not even sure that your argument even EXISTS, or that I'm even argueing about this argument ... ahhh I'm lost in paradoxes. freshgavin TALK 00:43, 26 January 2006 (UTC)

Why aren't there sex-linked diseases that are carried on the Y chromosome (or are there)?
I think this is a plot by the female gender. (CABAL!) — Ilyan e p (Talk) 01:31, 25 January 2006 (UTC)
Because there is little essential information carried on the Y chromosome. Every human has an X, but 50% of the human race lacks a Y, so it has to be dispensable. The only significant Y linked disease is the absence or nonfunction of SRY, which leads to sex reversal (XY genotype, female phenotype). It's a genetically "dead-end" condition because they are usually not fertile. alteripse 01:38, 25 January 2006 (UTC)
Also, I'm fairly cetain that there are some, though not many. The reason for this is twofold. One, any major life-threatening diseases can only be transferred directly from father to son. Another is that there are no carriers. Females aren't affected by sex-linked diseases as much because most of those diseases are found on the X chromosone. Since they have two X chroms, unless both chroms are affected, the unaffected X chrom just takes over. In this way, they have a chance of being unnafected but passing on a defected X. An affected Male Y chromosone doesn't have another Y who can take over. --
Herzog 01:44, 25 January 2006 (UTC)
Several types of azoospermia are linked to mutations in genes on the Y chromosome. But because these conditions decrease fertility, there is a strong evolutionary bias against them. -- WS 13:14, 26 January 2006 (UTC) The Sex linkage article comes close to defining sex-linked disease genes as being on the X chromosome. Some genetics texts seem reluctant to describe Y-linked defects as sex-linked disease ( example).

What is the technological reason for using any interlaced video format with HDTV? As far as I understand the interlacing technique was invented to get around the fluorescent's short persistence phenomenon, in order to reduce flickering on Cathode Ray Tube displays (CRTs). With the invention of the plasma screens and since HDTV targets mostly those screens, this technique seems to be obsolete and not necessary anymore (plasma screens do not suffer from the short persistence like CRTs). I expected any new format to abandon the interlacing technology completely and concentrate on compression using the modern technology (Spatial / Temporal redundancy reduction using Motion Compensation and DCT). Transmitting 60 fields per second or 30 full frames per second consumes the same bandwidth however if the video is interlaced the receiver must de-interlace it, which consumes serious amount of CPU power and result in inferior quality.
Why we are still using interlaced video for HDTV???

Is it true that the muscle is less heavy than the fat ?
I've heard that reheating spinach makes it toxic. The spinach article says nothing about it and a question at the talk page hasn't gotten a conclusive answer. Anyone here know? The reason I ask is that I regularly eat (frozen) spinach, to which I add milk, feta and lemon juice, which requires reheating. If there is any truth in the story, does it apply to this or only to serious cooling (eg in the fridge to eat the next day)?

What is a "head to head" clinical trial?
Matching two similar treatments to see which is better. For example, recruiting the next 20 patients with ear infections for a trial.

Measure all the relevant clinical parameters you can think of, such as fluid remaining in the ear at 10 and 20 days, number of days until pain gone, number of days until fever gone, number of days of school or work missed, and so forth. If this was your idea, you write it up for a medical journal.

How many satellites do you need to be able to see the whole surface of a planet from at least one of them at any moment? If the size of the planet matters, it's about half earth radius. My first guess was three (in GSO) but I don't think you'd be able to see the poles (esp. if there are valleys, etc. -- 대조 | Talk 06:10, 26 January 2006 (UTC)
In reference to the theoretical rather than the real-world version of the problem, four is the minimum number of points you need to be able to view the whole world from them. Two points opposite each other leave a ring uncovered (since they can't be at infinite distance), and three points in a triangle leave two poles uncovered. But the question asked about satellites, not points in space. A satellite's orbit has to lie in a plane that passes through the center of the Earth, so it's not possible to have 4 satellites maintain a tetrahedral configuration.
There is an easy solution using 6 satellites: just put 3 each in two perpendicular orbits, e.g. an equatorial orbit and a polar orbit, spacing them equally around each orbit. By arranging things more trickily, you can do it with 5. But when this question was asked in the newsgroup rec.puzzles in 1994, Stein Kulseth topped that with this clever solution using 4 satellites in orbits that are nearly, but not quite, circular, and each in a slightly different orbital plane.
For real-world practicality, the 6-satellite solution would probably be best. --Anonymous, 08:10 UTC, January 26, 2006.

(Not that kind of pot...)
I recently bought a cheap stainless steel pot from IKEA, and have noticed that when using it to boil water (practically all I've used it for) it gives off quite a harsh, chemical, metallic smell. I've noticed this before with cheap pots in the past (which is why I usually use my much-loved cast iron and copper...).

When I first read this I thought it was the smell of pot (marijuana) which has a somewhat metallic smell. (unsigned comment by User:12.41.204.3)
If you've ever boiled water and 'forgotten' about the pan that could be your culprit. I've burned at least 1 pan that way and it gives off a horrible smell after that, even to the point that it made my eggs smell bad too. I didn't die but I threw the pan away soon after that; it was only about $2. freshgavin TALK 23:44, 26 January 2006 (UTC)

We have a constant problem with computer support here. You give a person a website over the phone or through email. They say it doesn't come up. You test it and it works. After going back and forth, you walk over to the next building and watch them type the URL in Google's search box and hit enter. This isn't a one-time issue. This happens over and over and over. I've even asked people, "Are you typing the address into Google or the address bar?" They say they are typing it into the address bar, but when you check, they are typing it into Google. Is this an anomoly of Google idiots here or is this a problem others have?

Both of my parents do the exact thing you describe, have done so for years, and steadfastly refuse to change their habits because the way they do it is "good enough" for them. (Nor are they willing to learn the meaning of the most basic terms such as "address bar". I haven't even been able to get them to understand that they can have more than one browser window open at the same time; I'm afraid to bring up the concept of tabs.) Short of changing the home page in their browsers to a blank screen (which would probably result in them cutting me out of their will), I don't see what can be done about it. All you can do is figure out some way of phrasing your question so you can at least be able to tell whether your given idiot valued employee is actually using the address bar or not and then ordering them to try the address bar if they haven't already. Perhaps something like, "Do you see the line of icons at the top of the window that say 'Back', 'forward', 'reload', and so on? You do? Goooood. Now see that long white box to the right of it? Goooood. Now take your mouse and point it at the pretty long white box ...

It would be neat to test this scientifically. We could come up with something similar to tests for color-blindness, a series of dots with only a subtle color difference, that, if detected, allows you to see a hidden picture. If you couldn't make out the pic normally, but could after eating spicy foods, that would be proof that it works. Even more exciting would be if nobody else could see the pic, but only you could after eating the spice. This would prove it's not just a perception issue, but that your eyesight really was enhanced over a normal person's eyesight. If that was the case, isolating the chemical(s) causing this effect would be the next step, leading to a new nutritional supplement. StuRat 08:00, 27 January 2006 (UTC)

Why would you put a space elevator at the Equator? Wouldn't the most obvious place be the North or south pole? That way it would be in generally the same spot.
I'm not convinced of the feasibility of a space elevator. Finding materials which can withstand the forces would be quite an issue. Assuming they are found, and the elevator shaft can be built for a mere million dollars per kilometer, at a height of 35,786 km that would still be 36 trillion dollars, which nobody seems to have just lying around. If a world effort was made to build it (over decades), then some political method would be needed to assure access to it by the contributors. This would be similar to issues with the Suez and Panama canals. Nobody would be willing to contribute that much money without knowing they have permanent access to the result. Perhaps an "international zone", similar to Antarctica, could be established around the base to prevent the surrounding country from having veto power over who can use it.

The term "human", in common usage, refers specifically to Homo sapiens. However, broadly speaking, it may also refer to any members of the genus Homo. See [95] (click on second definition, "noun"). Or for instance, when Homo floresiensis was discovered, Scientific American called it "The Littlest Human" on its cover. You will often find "modern humans" or "anatomically modern humans" written in texts dealing with human evolution to differentiate us from our close ancestors. — Knowledge Seeker দ 07:05, 27 January 2006 (UTC)
Another nitpick. The name hominid properly refers to a species in the family Hominidae, which is generally considered to include humans and the great apes — gorillas, chimpanzees and orangutans. Unfortunately there isn't a widely-understood scientific term meaning "modern humans and other hominids more closely related to humans than chimpanzees". In some classifications this group is classified as the subtribe Hominina, so you could try using the term homininan. But few people will understand what you mean. Gdr 12:23, 27 January 2006 (UTC)

Hi, I read in my sceince text book that it can be possible to use water as a fuel for the cars in near future. Hydrogen and Oxygen is diffused by electrolysis and the produced Hydrogen is combusted for producing energy.After combustion the Hydrogen gets oxydized and again forms water. But there are some problems like its difficult to control the combustion of Hydrogen because its like a blast. and because after combustion it form water in exhaust making it wet and electrolysis of water on large scale to produce enough energy to drive a car. But would it be possible to do this? If yes then it would be very revolutionary step in the world of science. Any explaination would be thankful. -- Manasmdk 10:54, 27 January 2006 (UTC)manasmdk
Hydrogen explosions are not difficult to control. Internal combustion engines use explosions all the time. There's also no problem with forming water in exhaust - bear in mind other fuels - gasoline, etc. produce water during combustion as well, as they are carbohydrates...in fact most of the energy in these fuels come from the release of protons (hydrogen) and high energy electrons which had been earlier stored in organic material for decades...when combined with a highly electronegative element like oxygen, energy is produced. Hydrogen doesn't have the high energy bond, but it still remains the primary source of energy in a fuel...so pure hydrogen is a fuel in itself. The problem is in its density - organic molecules tend to have more mass over less space because of intermolecular forces as well as sharing of electron orbital pairs, thereby making lots of fuels a liquid (including ethanol and gasoline)...for example propane or methane are less so (which is why it isn't often an automobile fuel). The difference is that gasoline might contain many impurities and pollutants, nitrites, sulfides, sulphates, etc. making it impure, when hydrogen would have no such mixtures. This is because organic matter such as plants extract minerals from the soil during their life, incorporate sulfur and nitrogen into their amino acids - when the proteins (made up of amino acids) decompose, the sulfur and the nitrogen in them breaks off and forms new compounds in the organic matter and become pollutants when burnt (forming nitrogen oxide, sulfur oxide, etc..

OK, I'm a newcomer to Linux, so try to ignore the stupidity of my questions and to try to give a simple answer. ;)
I'm trying to connect Knoppix on a LiveCD to my wireless router.

I borrowed some Music CD's from a friend and copied their contents on to my hard-disk.Coz I used Windows Media Player,the tracks are in the .wma format.I need to convert them to the mp3 format.How can I do that?Those CD's are not available now so I cant rip them directly.Some help required. Thnx in advance.
The fundamental problem is that WMA format is not designed to let you do what you want to do here. Moreover, it is specifically designed not to let you do what you want to do here. Microsoft doesn't want you converting those WMA files into any other format at all (let alone the popular but unprotected mp3 format), because in this case, it is more interested in keeping the record companies happy than it is in keeping you happy.
There are probably programs out there that can convert from WMA to mp3, but they are not going to be easy to find, because if they were easy to find, Microsoft would have found them and gotten them suppressed under the DMCA. There are probably people (here) who could tell you about those programs, but they're reluctant to, because telling people how to defeat copy protection can get you in almost as much trouble as defeating copy protection, which can get you in almost as much trouble (more trouble, really) than actually violating copyright.

Discussions about electric bills often come up where I work, and the issue of power factor relating to what you use and what you're billed for is often raised. Many suggest that the utility company charges for the uncorrected power you use, using peak current. This would mean that they are actually charging for KVA/H instead of KW/H, which would be deceptive at best. Does anyone know the metering method of typical house KW/H boxes that the util co's use to charge for power in the US? I didn't find much specific info in our Electricity Distribution category. -- Jmeden2000 17:43, 27 January 2006 (UTC)
Not to stop anyone from pondering this... but I found a fairly good answer after more reading in the Electric Power category's article on Electricity meter (should that article be attached to Category:Electricity_distribution?), which explains that most common meters use a method that does not account for reactive power and hence would meter true wattage. Although, it's not terribly specific so if anyone has more info I would love to hear it. -- Jmeden2000 18:43, 27 January 2006 (UTC)
I'd like to point out that, as long as all power companies do it the same way, it doesn't matter, since they charge whatever either competition or the state governments will let them get away with. For example, if a utility sells one billion tweebles of power each year and it costs them a billion dollars, the state government may allow them to charge $1.10 per tweeble for a fair profit of 10%. On the other hand, if they claim they sell two billion tweebles a year at a cost of a billion dollars, the state would allow them to charge $0.55 per tweeble for a fair profit of 10%. So, the cost to the consumers will be $1.1 billion, either way you do it. In areas where different power companies compete, the forces of competition would dictate a similar outcome.

Damn small linux for example is available as a live cd so you can try it out without affecting your windows system.

Hi could someone tell me how long it takes vicodin to clear ones system , so it would not be detected in a urine test? Thanks Carl
I think there is another way of understanding what the 72 hour urine sample means. The recovery of 26% [111] during 72 hours is part of the analysis of total drug disposition (e.g., about 26% is excreted unchanged in the urine as opposed to being metabolized to other substances in the body). It almost certainly does not mean "...leaving 74% of the drug to be excreted over the next few days."
Unfortunately that figure does not give us the info to answer the question, which appears to be "how many days after ingestion of some vicodin will it no longer be detectable by a standard commercial urine drug screen?" I do not know the answer, but it would almost certainly depend on the amount ingested in the 2-3 days prior to stopping. The best answer might be found by googling for websites that coach people on beating drug tests, or the commercial sites of companies that make drug screening tests for employers and law enforcement. This is not a topic I have expertise in so I don't know what is readily available online. alteripse 17:27, 29 January 2006 (UTC)

There's been a lot of hype concerning the whole future hydrogen society. But I was sort of wondering why I would be so great...
A vehicle needs X energy to travel from point A to point B. It's irrelevant whether this energy comes from oil, gas, ethanol or hydrogen - X remains constant. So, you can collect solar energy in mechanical solar cells and "store" it in hydrogen or you can collect solar energy in organic solar cells (crops) and "store" it in ethanol.
So the question is - if the basic principles are so similar - why would hydrogen be better than ethanol...?

Has anyone to your knowledge been able to get o off lithium without going to other medication? My psychiatrist believes I was misdiagnosed my original diagnosis: Bi-polar. New diagnosis: PTSD. Any help would be appreciated! Thank you.
Lots of people have been on and off lithium or any other psychotropic drug. The problem with psychotropics is that there is no blood test that tells a psychiatrist exactly what disease a person with a mood problem has, and how much benefit can be expected from a given psychotropic drug. Therefore many people try more than one over a period of months or years before finding one that helps or finding other resolutions. Persevere and good luck. alteripse 00:36, 30 January 2006 (UTC)

Are there any natural lakes (not manmade) in Ohio besides Lake Erie?
I got this idea to make a system to protect the earth from asteroids.
1)A giant pipe 30kms long, 500m wide with 60cm thick walls would be built out of some metal (steel)
2)It would be put into an isolated part of the southern ocean.
3)A giant empty spherical durable metal foil bag 1/4 the size of the moon would be loaded into the pipe.
4)Ocean water would be pumped into the bag (ocean wildlife issues would be taken care of beforehand)
5)When the bag is full it would be pushed with rockets higher so that the water would freeze
6)The new moon would be in earth's orbit until needed, then it would be blasted towards the asteroid to deflect it.
!!!!!!!!!The new moon could also just be to look nice!!!!!!!!!!
>>>How much do you reckon this would cost? (I'm planning to make this as a weekend project)
PROS: asteroid sheild, all the water taken off earth would expose extra land, the tube could be remelted and used.
CON: cost
--Anonymous~Thinker `.............................................................
+(BTW, I'm the guy who made this question) The ice moon would be smaller and easier to move then the real moon. ALSO: the moon isn't meant to be a 'sheild' per se, it would simply be boosted with rockets towards the asteroid long before the asteroid would actually reach earth, to deflect it (the asteroid). I originally thought that the ice moon could be covered with giant screens on one side and solar cells on the other. The screens would play comercials 24/7. Or they could be used to display the current time (the time would change, and display the times of different time zones). +Now, the cost would be 5yottadollars...so how much money exists on all of earth at this time?
User:AlMac| (talk) 08:56, 31 January 2006 (UTC)
+Elaborating on what was said, the ice moon wouldn't be made, and then lifted. It would be filled while 30kms about earth, so it would just need to be boosted. Incase someone doesn't get it, I'm including a picture. File:Earthplan.JPG

In the month of January I find myself blowing my nose more often than I do the rest of the year put together. Question: Is it better for the environment to put my used tissue in the bin or in the toilet (flushing only when I would usually flush, of course)?
I'm wodering if we're tackling this question the right way. The question as posed has quite a number of variables, and we've been neglecting one of them. If the hanky is left in the bin, then the germs will still be in the household environment until the bin is emptied. A cloth handkerchief, while better environmentally than a paper hanky, will compound the problem, since you'll be carrying the germs in your pocket. Toilets usually contain anti-germ treatments in the "cistern blue" fresheners, so from that point of view at least toilet disposal has advantages. Grutness... wha? 02:13, 31 January 2006 (UTC)

I'm trying to achieve what I thought would be a very straightforward effect -- a header with several items spaced evenly across the top of the page. It's trivial to do with tables, but I've spent the better part of a day struggling with a solution based on div
elements and CSS, with no success.
In particular, I would like to set the widths of the items as percentages of the width of an enclosing div
element. I thought that using percentages with the width
attribute would do this, but the results I observe do not seem to follow this rule.
This is a stripped down version of the HTML:
<html> <head> <link rel="stylesheet" type="text/css" href="index.css"> </head> <body> <!-- This works --> <table class="header"> <tr> <td class="header_left"> Logo </td> <td class="header_middle"> Welcome to my site. </td> <td class="header_right"> <a href="contactus">Contact us</a> </td> </tr> </div> <!-- This doesn't work --> <div class="header"> <div class="header_left"> Logo </div> <div class="header_middle"> Welcome to my site. </div> <div class="header_right"> <a href="contactus">Contact us</a> </div> </div> </body> </html>
and the stylesheet:
body { background: gray; } .header { background: white; width: 100%; } .header_left, .header_middle, .header_right { display: table-cell; background: lightgray; text-align: center; } .header_left { width: 25%; } .header_middle { width: 50%; } .header_right { width: 25%; }
I've tried many variations on this, with no luck. I've been testing with recent versions of Firefox and Opera, and would like the page to work in IE as well.

I wonder, what is the minimum time it would take to terraform a planet like Mars?A few hundered years?A few thousand years?Hundreds of thousands of years?(Let's suppose we spend a minimum of ten billion US dollars on the project every year.)
In terms of the finished result, a terraformed Venus would be a more attractive prospect than a terraformed Mars. However, it would be a far more difficult task to achieve and would take tens of thousands of years with our current technology level, if it were possible at all. The planet's atmosphere is deadly, and cleaning it would be extremely difficult, although some forms of terrestrial lichens and mosses could probably just about survive it the way it is now and might be utilised to improve it a little. Mars is probably the easier bet if we wanted to try any terraforming, and has the added advantage that we know that several useful chemicals are available on or just below the planet's surface that could be used in the process.

How can u say science is greater than arts?
It has been said that any science with more than seven variables becomes an art (can't remember who said it, unfortunately...).

Why must governments be bullied into supporting alternate religions? and tolerance of aithiests and other hate mongers? Can't we just accpet that the United States in a Christian Nation?
