I once did the calculation for water with salt added to find out if that would make potatoes cook faster, and the result was something barely over 100 C (just a tenth of a degree or something). I assume sea water won't be much different, so my guess is something like 100.1 C.

The dictionary describes it as a colourless, odourless liquid. if this is true why are oceans green and blue.

I understand how to use Runge-Kutta methods to solve a first order differential equation, but I'm not sure how to adapt it to a second order equation like the harmonic oscillator. I'd assume you'd break the second order equation into two first order equations, (and I have solved this problem using Euler's method) but I don't know how to adapt the more accurate RK procedure to two coupled equations.
Anyone know of any good references either in print or online to help me learn it? Thanks. Vonspringer 04:08, 1 November 2005 (UTC)

WHAT IS RED HAT ENTERPRISE AND WHY IS IT AN OPTION
WHAT IS RED HAT ENTERPRISE LINUX?
Space craft that go beyond Mars are quite often accelerated using a sling shot effect, by passing close by some heavenly body. Of course they will get accelerated when they approach it, but after that they have to escape the gravitational pull to continue, which would annihilate the effect. So how does this work? I imagine it has something to do with either the change in direction or approaching the planet (or whatever) 'from behind' (relative to its motion), thus not using the gravitational pull but the speed of the planet.

There are three types of orbital motion, parabolic, (ballistic trajectory) elliptical, and hyperbolic. By approaching a planet in a hyberbolic orbit, we don't accelerate from the gravity of the planet, but we acquire the velocity or twice the velocity of the planet's motion. If the planet was stationary, all we would do is change direction. Since the planet is moving, we acquire the velocity of the planet while accelerating around it in the hyperbolic orbit. A good explanation is here. [2] Dominick (ŤαĿĶ) 12:48, 1 November 2005 (UTC)
The key is that the spacecraft steals some angular momentum from the planet. Since the planet is so much bigger than the spacecraft, the planet's speed changes negligibly, but the spacecraft gets a big boost. If the planet were stationary than the trick would only change the spacecraft's direction. — Laura Scudder | Talk 16:37, 1 November 2005 (UTC)
The trick to thinking of this situation easily is to use frames of reference. Imagine you are standing on a road, looking south, and a car comes toward you at a speed of 50 (mph or km/h, whatever units they use where you live). You throw a ball directly toward the front of the car, at a speed of 40, and step out of the way. They are closing at a relative speed of 90... that is, in the car's frame of reference, the ball is moving south at a speed of 90. We assume that the car and the ball are perfectly elastic bodies, that is, the ball does not waste energy in denting the car or anything like that. Then the ball will bounce back from the car at a speed of 90 in the opposite direction, north. But that's 90 relative to the car... so in your frame of reference it's now going at 140! Don't try this at home!
Now consider the same situation, only this time you turn away from the car and throw the ball north at a speed of 20 (before stepping aside), so that the car catches up with it. The car is moving north at 50, so in the car's frame of reference the ball is moving south at 30. Hitting the car, it bounces north at 30 in the car's frame of reference... which is 80 in yours. Same idea as the first experiment, although the speed change is less dramatic in this case.
In both cases, if you measure closely you will find that the car has slowed a little, as the ball stole some of its momentum. This shows up as a change in the speeds of the two frames of reference relative to each other. But for purposes of understanding the experiment, this can be pretty much ignored.
The car example is one-dimensional. For planets and spacecraft, you have to think in at least two dimensions. Here is how it looks in the planet's frame of reference: The spacecraft approaches from a distance and falls toward the planet on an off-center path. The planet's gravity causes it to follow a hyperbolic orbit. The symmetry of this shape means that the spacecraft departs at the same speed as it was approaching originally, but in a different direction. The effect is very much as if the spacecraft had simply bounced off the planet, even though it is being pulled by the planet's gravity, and not pushed by the (electromagnetic) forces involved in bouncing a ball.
Okay now, in your frame of reference, the planet is moving along its orbit. For simplicity, say it comes up almost directly behind she spacecraft, like the second car/ball example. Then in your frame of reference, the spacecraft may end up moving in very much the same direction as before, but considerably faster. The details of the before and after directions are actually more complicated and not the sort of thing you can do in your head; for one thing, it depends on how close the spacecraft comes to the planet. But this gives the general idea.
(Typically the planet and spacecraft will be moving in the same direction, like the second car example; this is because the Earth's own orbit, which is also in the same direction, determines which orbits can be reached at reasonable cost.)
You asked if it is "not using the gravitational pull but the speed of the planet". You should now see that it is using the gravitational pull in order to use the speed of the planet. It has stolen a tiny bit of momentum from the planet (and, in the same interaction, some of its angular momentum as well).

But as to the parenthesis... in Florian Cajori's A History of Mathematical Notations it is called a lunar sign.

What is the scientific reason behind the fact that the number of columns of seeds in a corn cob is always even ?
I'm not sure, but I would guess that it is due to nature's preference for bilateral symmetry. This is a handy trick for reducing the number of instructions required to "build" and organism. A bilatrally symmetric corn cob will always have an even number of seed rows, because the instruction is (basically) "build one seed row on each side".

I just read an article concerning the possible discovery of a supermassive blackhole at the center of our galaxy. And that sparked my curiosity about wether our galaxy is expanding or contracting?
I know that all galaxies of the universe are moving away from each other, Expanding, at equal speeds, and that as a whole the universe is in fact expanding. But then there are blackholes, such as at the center of our galaxy, that are so dense with matter that the gravitational force is pulling in surrounding planets and stars like a cosmic whirpool. This would be a form of galactic contraction, right?
Also where does the matter and energy go? Scientists say that it completely disappears, because no light can escape a blackhole. Could these be the sites of new universes, turning the dimensions inside out to create new alternate, and invisible (to us) worlds?
I would enjoy any guesses or information you may have.
thanks- brian
Just to simplify the answers on black holes affecting expansion or contraction of the universe...as massive as black holes in the center of galaxies may be, they are a tiny portion of all the mass in the universe, and thus don't have much effect on the expansion or contraction of the universe. Also, whether the mass was evenly distributed or in a series of black holes might not make much difference in the calculations, if the total mass is the same. The oddest thing about the expansion of the universe, is that it seems to be expanding at an ever increasing rate. This requires some exotic theories to explain. StuRat 05:17, 4 November 2005 (UTC)
Fred’s contribution to cosmology is what he was best known for by the general public. In 1948 he, and Bondi and Gold, in two separate papers (Hoyle 1948; Bondi and Gold 1948), put forward the idea that the Universe is in a steady state. Fred’s contribution was the introduction of an extra term Cµν into the Einstein field equations. This extra term represents the creation of matter. At least initially the form in which matter was created was not specified, although of course it had to be electrically neutral. More recent theory, which explains the isotropy and homogeneity of the Universe, namely the ‘inflation’ theory, has a metric which is identical to that of the C -field cosmology.
Regardless of the presence of a black hole at the center of our Galaxy, both the Universe ( everything we detect ), and our local cluster ( us, and nearby galaxies), and us ( the Milky Way Galaxy ) is expanding, evidensed by the observation of the redshift. ( light emissions shifted toward longer red wavelengths due to doppler shift ). The cosmological question is what will the end look like, and gives rise to 3 1/2 theories:
Note: This is an extrodinary refrence: [ Cosmology FAQ ]
"Tell your Congressman and Senators to support astrophysics research at NASA, NSF, and DOE."
"The original S-S universe and its more recent successors all posit a universe that is infinite in extent. The expansion everywhere is compensated by episodes of creation (mini bangs in recent models) so as to maintain an overall SS state. The velocity of light is constant."

So I learned the hard way that std::vector containers may internally resize and "reorganize" during execution of your program, meaning that if you have a container of objects, you aren't guaranteed that, &mycontainer[53] will always equal the same reference address.
I've pretty much figured out a solid configuration to set up geometric mesh structures but certain things I didn't know about the STL (not really having used it often) is making the actual implementation a bit of a pain to make it fast and relatively free of fatal bugs. For meshes with efficient operations, I need to use a more memory-reliable(?) container, where &mycontainer[53] will always equal the same memory address regardless of whether that container has 60 items, or 600,000 items.
STL documentation doesn't really explain the nitty-gritty internals of how these containers function behind-the-curtains so I'm a bit hesitant to just change my program by a kneejerk reaction and jump on any other of the STL containers. What's the most "safe" C++ STL container to use, if any, that still allows for constant-time O(1) lookups (even O(log n) isn't acceptable for meshes with hundreds of thousands of vertices and polygons meant to be rendered many dozen times per second) and, most importantly, guarantees every object in it will always have the same memory address that it did when you first inserted it any time ago?
Also, on a somewhat related note, if there are any math-dummy-friendly books by reputable authors about implementing graphics structures in C or C++ that anyone could recommend I'd appreciate it greatly. I understand meshes but I also intend on allowing animation and deformation when I get this current mess sorted out, but vertex-deformation weighted and hierarchal IK animation seems a bit scary to me -- plus, practicing this with trial and error, I could just as well be currently doing some other faux pas I'm not conscious of. -- I am not good at running 22:00, 4 November 2005 (UTC)

On the news we hear it all the time: "Bird flu is pretty safe now, but if it mutates to a form that could be transmitted between humans, then it could become a pandemic"
Are the odds of bird flu mutating into such a form higher than the odds of similar mutations? We never hear "If the HIV virus mutates to being transmittable by sneezing then...", "If the cold virus mutates into being worse than pneumonia and remain as catching then...", "If the ebola virus mutates to being transmittable by mosquito then...", etc etc.
Is there a specific reason why we should be more worried about bird flu mutating in such a manner?

I'm beginning to learn Java, and I have a good beginner's guidebook to it. It provides this very simple code:
class example { public static void main(String args[]) { System.out.println("Java drives the web."); } }
I've looked over it and understood what it's supposed to do. I've stored it in example.java, and it compiles successfully to example.class (using javac.exe). However, java.exe doesn't want to run it. It tells me:
Exception in thread "main" java.lang.NoClassDefFoundError: D:\David's Stuff\David's Java stuff\example
(D:\David's Stuff\David's Java stuff is the directory I've put it in.)

Why and how does a decay of a neutron give rise to a neutrino and an electron? I see in the first place that since neutrinos and electrons aren't part of quarks at all, how does the release of them somehow change one of the down quarks into an up quark, seeing that quarks are fundamental particles and aren't composed of neutrinos or electrons. Is this something relating with E=mc², where one of the quarks get turned into pure energy, and is reformed into a new quark? And in order to comply with the laws of conservation, would it suggest some quarks have more energy than other quarks, or is this relative to their arrangement depending on what type of quarks there are in a given moment? Two down quarks and one up quark after all, seem to have more energy than one down quark and two up quarks, since the former can produce the same thing PLUS a neutrino and an electron? And since overall, it bears the material that has the abilities of both proton and electron, why is this not exercised in the atom, affecting proton/electron number, etc.? -- Natalinasmpf 12:20, 5 November 2005 (UTC)
"A free neutron will decay with a half-life of about 10.3 minutes but it is stable if combined into a nucleus. This decay is an example of beta decay with the emission of an electron and an electron antineutrino." "Momentum and energy for the two-particle decay are constrained to these values, but this is not the way nature behaves."
Artoftransformation 01:00, 6 November 2005 (UTC)
As for the question of two up and one down having more energy than one up and two down : You can't divide the energy up among the quarks only like this. There are a lot of gluons involved. The energy for the beta decay of one quark comes from the whole system of the three quarks plus all the gluons, not from the quark that decays.

Why do light rays/beams travel in straight lines???
A single application of a force makes something travel in a straight line. Add another force is when you get a curve. Light is driven by one force (to roughly but technically incorrectly describe it)....only when you add another force, like a mirror, or gravity (for example the electrons in the silver molecules of the mirror apply an additional force to the light waves) that the path changes. When you throw a curveball for example, your muscles are applying at least two different directions of force. -- Natalinasmpf 19:42, 5 November 2005 (UTC)
I would ask you to repeat a thought experment. When asked by reporters how Einstien came up with Relitivity, he said 'What would I see if I rode on a beam of light?' Lets see if we can recreate what he saw. (Keep in mind that a frame of refrence is consistant. Right angles are right angles ). A beam of light in a vacuum would travel at the limit of speed. Nothing could travel faster. If it was traveling near a large mass, the local frame of refrence would curve and the light beam would continue straight through it, but to an outside observer( remote frame of refrence, the light beam would appear to bend, but it according to General Relitivity, it wouldnt. Again, its the local frame of refrence that although consistant with itself, would appear to a remote frame of refrence as bending. Artoftransformation 23:48, 5 November 2005 (UTC)
Just a thought with no basis whatsoever (and an attempt at that 'extraordinary simplicity'). Isn't a straight line defined by how light travels? DirkvdM 16:48, 6 November 2005 (UTC)

Suppose I have a ball of some mysterious substance that is unaffected by any force - especially gravity and electromagnetic forces. If I let go of this ball (of course, it would be hard to hold in the first place), what would happen to it? Would it move relative to me? Where would it go?-- Fangz 17:02, 5 November 2005 (UTC)
The way I see it: of course, it would be hard to hold in the first place. No, you just WOULDN'T be able to hold it at all, because you'd NEED to use a force on the object for this. Since sub-atomical electrical forces is what makes you hit a wall, and not go through it, such substance would just go through everything. But it doesn't stop there, because if the mysterious substance is completely immune to any forces, a particle of such substance wouldn't have any force on other particles of the same substance, so it'd just become a floating mass of random moving particles that permeate everything on their way. ☢ Ҡieff⌇ ↯ 23:30, 6 November 2005 (UTC)

I've been trying to start up a personal study of the Relativity Theory and related concepts. My problem is as follows. Consider a situation with two clocks, A and B. From the viewpoint of clock A, clock B is moving at a constant speed. If I understand special relativity correctly, time moves faster for clock B, because it is moving. When clock B returns from it's journey, clock A wil be a little bit behind clock B. So far so good, but if we choose clock B as a reference frame, instead, it's clock A that's moving, so clock A should be moving faster, and clock B should be behind when they are re-united.
I feel I have some fundamental misunderstanding of the theory, and I was hoping someone might clear this up for me (or at least point me to some page that explains this).
While I'm at it, I was also wondering if somebody could recommend a good book explaining both special and general relativity, at a thorough level. I'm quite willing to make an effort and study the complex geometry involved in general relativity, but right now, I don't really know where to start.
Many thanks, risk 13:40, 6 November 2005 (UTC)

Well, you have K drawn numbers and N-K non-drawn, then there are

The force of gravity pulls the Earth upward, toward to people in the air, by an amount equal to the downward forces. Otherwsie, if any force is exerted on the Earth in just one direction, such as when an atom in space hits the Earth at high speed, the Earth will move, just by an extremely small amount, due to the difference in mass.

The moon and the sun rotate, but asteroids and comets don't?

The solar wind must push the planets out a bit further than their natural orbits (based on their orbital velocities). I would expect this effect to increase proportionally with the cross-sectional area of the planet, and decrease proportionally with the planet's mass, and decrease in proportion to the square of the planet's distance from the Sun. Now, a planet with a highly elliptical orbit would be expected to be pushed out more when closer to the Sun and less when further from the Sun. My question is, would this tend to make all orbits more circular over billions of years ? If so, I would expect the inner planets to make this adjustment more quickly than the outer planets. The innermost planet, Mercury, might have it's orbit disrupted by solar flares, etc., which could negate this effect.
Looking at the following chart, it does appear that the eccentricity of the planets Venus, Earth, and Mars follow the expected pattern:
- Eccentricity..Planet
- =========.======
- 0.20563069...Mercury
- 0.00677323...Venus
- 0.01671022...Earth
- 0.09341233...Mars

Ok, time for some calcs:
From: http://www.lgarde.com/people/papers/TESS/ (a site on solar sails)...
"The areal density, including payload, will be 3.63 g/m^2, giving a characteristic acceleration of 2.26 mm/sec^2" (0.00226 m/sec^2)
Earth's mass = 5.9736×10^24 kg = 5.9736×10^27 g
Earth's cross sectional area = piR^2 = pi(6,372.795 km)^2 = 127,587,980 km^2 = 1.2758798×10^14 m^2
Earth's areal mass = 5.9736×10^27 g / 1.2758798×10^14 m^2 = 4.882×10^13 g/m^2
Set up a proportion:
[3.62 g/m^2] / [4.882×10^13 g/m^2] = a / [0.00226 m/sec^2]
a = 1.676 ×10^(-16) m/s^2 (accel of the Earth if only solar wind was acting upon it)
v = 6.033 ×10^(-13) m/s hour (speed after 1 hour)
v = 1.448 ×10^(-11) m/s day (speed after 1 day)
v = 5.288 ×10^(-9) m/s year (speed after 1 year)
v = 5.288 m/s (speed after a billion years)
At that speed it would take about 1.8 years for the Earth's orbital radius to double.
So, I conclude that the solar wind is sufficient to have noticeable effects over time, if unbalanced. The Earth would have long ago been blown out of the solar system if this force was unbalanced regarding the mean orbital distance. My theory is that it is balanced, in the case of average orbital radius, but not in the case of eccentricity of the orbit, which should then even out over time. StuRat 23:46, 7 November 2005 (UTC)

I heard a recent discussion on the radio about Comets & Asteroids.

Apparently the elements for water would not or could not combine on earth without a vast input of energy. Any comments would be welcome.
"The component of primordial solids of major importance as a source for terrestrial water is hydroxyl ion. This ion forms a regular structural component in magnesium and iron hydroxysilicates, which form the major mass of carbonaceous chondrites of Type I (Wiik, 1956). (Crystal hydrates of magnesium and sodium sulfates found in carbonaceous chondrites are probably not generated in space where they are unstable; they are likely to be forming by reaction with water vapor in terrestrial museums.)"
"The fact that meteorite materials carry sufficient hydroxyl to account for the entire hydrosphere on Earth should not be taken to mean that the Earth formed from any of these specific materials, which probably represent different condensation events and regions in space. But the observations [487] imply that primordial condensates in different parts of the solar system, although varying markedly in chemical composition (ch. 20), have incorporated substantial amounts of volatiles, which were subsequently released in the accretional hot-spot front during the formation of the planets (sec. 26.3.2)."

This question goes back to burning in cigarettes, what does the alternative cigarettes use to make their smokes burn since they don't use tobacco leaves?
What? Cigarettes are full of tobacco, and a lot of other things. If you must smoke, smoke cigars. Dominick (ŤαĿĶ) 19:48, 8 November 2005 (UTC)
No, they have some that are filled with things like a blend of smoking herbs: Marshmallow, Yerba Santa, Damiana, Passion Flower, Jasmine and Ginseng. If there is no tobacco or nicotine what chemical aids these herbs in burning?
All these things can burn but not well, I agree. But is there specific chemicals added to these herbs or leaves that aid in their burning to make the burn slower and better?
Most dried leaves (including tobacco) burn pretty badly on their own. Commercial cigarettes tend to be doped with saltpeter and glycerin to make them burn more steadily, and save you having to relight them. The only thing keeping a hand-rolled plain leaf cigarette burning is the paper and an occasional relight. The burn will also depend on how you roll it - how densely packed, how fat the cigarette is. But for commercial herbal cigarettes, I imagine they would be doped with glycerin and saltpeter like commercial tobacco cigarettes. 84.43.1.92 11:01, 14 November 2005 (UTC)
I'm researching the skin effect and referenced the article so titled. Digging through the equations in various articles, I see several examples provided for copper at various frequencies.
Replicating the table should be straight forward. Using articles found under "Resistivity" and "Permeability (electromagetism)" and "angular frequency", I find that the formulas provided do not work with the sample tables provided in the various articles.
My suspicion is that the units between the articles are messed up and not comparable.
For example:
Copper wire at 10kHz is indicated as a skin depth of 0.66 mm.
Using resistivity of copper as 1.7 x 10^-8 (table in resistivity article
Angular velocity of 2pi/(1/10000)= 62831.85 (formula in angular velocity article)
Permeability of copper as 1.256629 (table in permeability article)
The result is 8.24-7 and no definition of units is described.
The table in Skin Effect indicates 0.66mm
What gives?
Why did you use angular velocity? Skin effect from tables is an exponential effect, current tends to travel and vary exponentially as you go into a conductor. Dominick (ŤαĿĶ) 21:33, 8 November 2005 (UTC)

My question is specifically in regards to the moon cresent: sometime it appears in a "vertical" position, at other times it appears in a more "horizontal" position.
No, no, no. This is simple: the lit side of the moon is lit by sunlight, so the lit side is always oriented directly toward the sun. With a crescent moon, this means that the inside of the crescent is oriented directly away from the sun. Draw a line from the center of the dark edge through the center of the lit edge and onward, and it points to the sun.
You can verify this by eye if you look at the moon in the daytime; of course, you must be careful not to hurt your eyes by staring at the sun. Similarly at night, the lit side of the moon points to wherever the sun is below the horizon, on its path (as seen from the earth's surface) from the sunset point back to the sunrise point. Note incidentally that this means that the unlit side of the moon is always the upward side, at night: if you see it any other way in a movie, you know they faked it and got it wrong. --Anonymous, 01:20 UTC, November 9, 2005

The developmental stages of organisms sometimes reflect aspects of the biological history of the species. The organism's earlier evolutionary forms would have been superseded by its later, modified physiology; thus, its earlier forms would have passed into redundancy, expressed only as 'shadows' of previously existing physiology. Taking the butterfly as an example, during the time that it was evolving wings, it would have 'left behind' its previous wingless form - it would not have lived part of its life as a wingless orgasm, then after metamorphosis changed into a partly winged creature (its evolving into a fully winged creature not having been completed yet). The butterfly's present developmental stages seem to show the expression of both the current final stage of evolutionary development as well as the earlier segmented caterpillar form being carried along in tandem as a fully functioning organism (albeit as a defined developmental stage). Why didn't the earlier physiological form of the organism, i.e. the caterpillar, get sloughed off and consigned to its evolutionary history?
Dudley Warrington
Thanks for the insights and contributions . I suppose I'm essentially asking what evolutionary mechanism leads to the development of the metamorphosis stage, without the organism evolving out of its earlier form (as expressed by the caterpillar). DW.

My brother is on a low salt diet due to high blood pressure. He recently had surgery which required that he get his fluids via saline solution. However, the sodium content in the saline caused his BP to spike dangerously. When he complained to the nurses, they said they only had one concentration of saline solution for patients. Is this true in general, or do lower concentrations exist for patients on reduced sodium diets ? StuRat 17:32, 9 November 2005 (UTC)
No, no, no. None of that info about saline concentration is relevant to your brother's blood pressure. BP does not respond acutely to saline and there are a number of risks from giving a hospitalized patient a hypotonic saline solution. The far more likely causes of acute high bp include pain, immobility, stress, discontinuation of home meds, accurate detection of higher bp than expected, and some other things. This is not the place to second guess your brother's treatment. alteripse 22:17, 9 November 2005 (UTC)
IV normal saline solution contains sodium at the same concentration as exists the blood. The cells in your body expect a certain ambient sodium concentration, and get upset if you muck with that. (Too low results in hyponatremia). To simplify, IV fluid with low sodium concentration will be driven by osmosis into the body's cells; it won't stay in circulation where it presumably is wanted. The salt in normal saline won't cause a spike in blood pressure when administered, because it's at the same concentration as what's already in the blood.
There are other things that may have caused the spike in blood pressure. Your brother can and should speak to his surgeon or his physician about them. (To pull one random example off the top of my head, I might ask if he received any sort of locally injected anaesthetic immediately before his BP went up. Lidocaine, for instance, contains a small amount of epinephrine to increase its effectiveness. However, if by random chance and bad luck the local injection hits a vein rather than just soft tissue, the spike of ephinephrine in the blood will cause increased heart rate, sweating, nervousness—the whole fight-or-flight response.) TenOfAllTrades( talk) 12:36, 10 November 2005 (UTC)
I don't believe he was expecting the worst, at least not from the saline solution. Admitedly, the surgery itself may have made him nervous, though. Here's a good source: [28]. This particular passage relates to my brother's case:
"....a large subset of patients with essential hypertension responds to salt loading and restriction with pronounced changes in blood pressure, which has led to the concept of salt sensitivity." StuRat 20:28, 10 November 2005 (UTC)
StuRat, I forgot you were the questioner and it was your brother. I still think an iv fluid error an extremely improbable explanation. In the US 3% saline usually comes in different sized bags, with red or bold labeling and often is not stored on the same ward supply shelves. It is very rarely used and would be an unlikely error, especilally since there are so many more common causes of sudden high BP in a hospitalized adult. alteripse 22:03, 10 November 2005 (UTC)
Good day.
I'm beginning work on a project - BPM - and I'm working with folks in IT. I've been doing a little research around Configuration Management and Change Management. I've run across these terms in an article discussing the benefits of Config. Management and the author mentioned these two terms in context of what might be tracked and managed.
I've not been able to find a reference that defines the diference between these two states.
Can you point me in the right direction?
Thanks.
Change management is for an existing system for which changes must be tracked. Configuration management and Software configuration management ( SCM) are the more general case for both new and existing systems. In other words, a production configuration is for an existing configuration, because no one in his right mind would go to production without a pilot plant. A Stored configuration is something which existed in the past, with possibly a list of the capabilities that it offered. Someone experienced would also be able to list the deficiencies in both the Stored and Existing configurations. The changes are tested against Regression tests and the successes/failures are tracked in one of these systems as well. In other words you need multiple configurations to get anything done nowadays.

The best explanation for the second question is that laying a large number of eggs is an r-selection reproductive strategy. Many species produce an enormous excess of gametes or offspring because only a few will survive. This is true for most insect species, and for most species that deposit gametes or young in a risky environment. In this reproductive strategy the parent invests almost nothing in the way of effort or food in the rearing, and most perish. The opposite is called K-selection, where only a small number of offspring are produced but the parents continue to invest large effort or food resources into rearing the offspring and a high proportion survive. alteripse 11:37, 10 November 2005 (UTC)

I saw this egg-inverting trick in a Japanese sushi manga:
The hero was in his restaurant when the old guy came. He said: "I'll sell you a chicken that lays inverted eggs." Our hero did not buy his words. So the old guy boiled an egg and opened it. Our hero was amazed to find the egg really has yolk on the outside and the white inside. He paid 100,000 Japanese Yen and accepted the chicken only to find out a week later, that chicken was a cock.
The old guy came to the other chef. This time he taught that chef the trick for 200,000 Yen so he can challenge our hero.
Our hero was totally hopeless. He went to his sushi teacher, only to find out his master tried to make it according to an antique cookbook while he was young. The book taught him to preserve the eggs in miso and rice bran. No, it didn't work.
At the day of the match, the bad chef made a sushi with an inverted chicken egg. People were amazed. However, our hero made a sushi with inverted multiple quail eggs. The bad chef said to himself, "It's hard for me to do it with a large chicken egg. How could he make it with quail eggs?"
(You may want to use a large egg.)
(You may want to use a very small egg so the yolk adheres to the shell more evenly.)
Well, I plan to try it at home. I guess it is a magician's trick. But I know I am too clumsy. I can never be a good chef. The manga author said the egg white tend to adhere to the metal. I don't buy his theory. The only alternative explaination I can think of is the centrifugal force. So I guess I could do it with spinning. -- Toytoy 16:32, 10 November 2005 (UTC)
Hello, Digital radio is getting a lot of press & is very popular, despite the fact that the sound quality isn't as good as is purported, however I have always suspected that the fact that it is digital rather than analogue means that it is easier for it to be blocked or jammed by national governments.

Because I hate the movie, I decide to take my brand-new spaceship and fly away at c (hypothetically) to deep space in the opposing direction of the light coming from the screen to the Earth. The question is: When I'm still accelerating, say at 0,5c, I should see the movie slowing down (in my reference frame) and in the hypothetical arrival to c, the movie should stop due to time dilation. Can anyone explain me what do the photons do exactly here? Is it something like the photon from the screen chases me but not fast enough to catch me in finite time? Wouldn't this be in contradiction with the universal constancy of c?

It's probably just me being paranoid, but I'd rather put my mind to rest. A few weeks ago my class in Biology did a experiment where we extracted DNA from onion cells into test tubes, and then stained the DNA so that it would show up in the test tube. I'm not sure if we were supposed to add the stain ourselves or if the teacher was supposed to do it, but either way I added the DNA stain myself and got a little on my fingers. And at the time I thought it might be a tad dangerous - anything that stains an onion's DNA could affect mine (possibly?) - and it stained my fingers, but I washed most of it off and it disappeared soon enough, so I didn't think about it. But just now I've heard from a friend who did a different experiment, also using a DNA stain, and they were told not to get any on their skin or it could mess up their DNA. Which led me to worry. It probably doesn't help that I don't know which particular stains I used or they used, but I seem to recall it being blue. So am I in mortal danger, or is it nothing? I mean, the school wouldn't let us use something extremely dangerous, would they? -- Sum0 22:37, 10 November 2005 (UTC)

It's the Coral Sea near the Australia. It is 4.800.000 sq.km
That depends on how you define the sea and what constitutes a sea (as opposed to an ovean) in the first place. The Mediterranean Sea is well defined because the Strait of Gibraltar is so narrow, but where would you put the border between the Coral Sea and the Tasman Sea? (And why are they separate seas in the first place?) That's pretty arbitrary and I suppose that's the reason figures on the size of a sea may differ. DirkvdM 11:58, 11 November 2005 (UTC)

I'm just wondering if there's a way to do something in Acrobat. Let's say I have a PDF with, say, six pages: ABCDEF. Is there a practical way to turn it into AABBCCDDEEFF? By "practical", I mean, "other than doing it one page at a time". I'm interested in doing this to a document with about 150 pages, so the ability to scale it up is important. I couldn't figure out an obvious way to do this but it doesn't mean that it can't be done, of course. (The reason, by the way, is that the pages are scanned in as two to a page, horizontally. This is fine for printing, but for reading on the computer it is difficult. My theory was that if I could duplicate each page, I could then crop the even-only pages and odd-only pages so that they were left and right pages respectively, and make it so that each PDF page corresponded to only one page of the document, rather than two. If there's another way to accomplish this, I'm all ears.) -- Fastfission 19:19, 11 November 2005 (UTC)

I am learning about the blood coagulation cascade. While I understand that Thrombin catalyses more than one reaction, I believe that the most important of these is catalyzing fibrinogen to fibrin, so that stable clots can be formed. What I don't understand is, if the thrombin is available for previous reactions in the coagulation cascade, such as the conformation of factor VIII to factor VIIIa, then why isn't it possible to skip the all the previous steps of the cascade, moving directly to the formation of fibrin? Why are the previous steps necessary?

Do they have to be your own? And is this meant as a serious question? Ah, well, even it is not, it's an interresting bit of trivia. I'll take 'judge' to mean 'measure'. An anemometer would need some time to get up to speed and farts probably don't last long enough for that. Also, a fart is a narrow jet of air, and I don't think anemometers would be able to handle that (unless they're very small perhaps, which might also deal with the first problem). However, pressure anemometers probably don't have the first problem and a tube anemometer might not have the second problem either. But the thought of inserting a tube in my arse makes my cheeks somewhat anemic (now that's a rather lousy word joke even by my standards - and don't make jokes about which cheeks I mean, please).

A suggestion on QI last night, that I've once wondered about too. Considering that outer space is about 100 km up, wouldn't it be possible to build a ladder or lift that high, so we wouldn't need those expensive rockets? (A modern day tower of Babel.) Of course this would also cost a bit, but you'd only need to build it once. And working the lift would also cost energy, but I assume it would be much more efficient than a rocket, which probably spills most of its energy sideways. And the engine and fuel could remain on the ground in stead of having to be transported as well (I suppose this is the biggest advantage). Once there, a rocket would need only a fraction of the energy to get further out in space. If you go high enough, centrifugal forces of the rotating Earth might even be used, to the point that it actually generates power in stead of consuming it. This is getting to sound better and better as I write it. DirkvdM 15:40, 12 November 2005 (UTC)

I've read some internet postings saying it might be Norton screwing me up. I don't think I've changed any settings, but it's possible someone else has. Lot's of messages have suggested uninstalling and reinstalling Norton, but I don't have the original disks anymore, so I'd prefer not to.
Any suggestions?

electrical tester, that we use to see if current is there or not in sockets,...n when we use it even while standing on wooden stool the ckt gets completed n the bulb in tester glows how?? irrespective of the thickness of wooden stool(insulator)..how it happens??
from Avinash parhi,India
-- 59.93.129.191 02:33, 13 November 2005 (UTC)
He doesn't quite say so, but I suspect he's talking about the simplest kind of electrical tester, which has two leads and a neon lamp inside, along with a big old (100k or so) series current-limiting resistor, since small neon lamps require a ridiculously small amount of current. Secondly, I suspect he's asking about the case where you connect one lead of the neon tester to a hot wire, and hold the other lead in your hand. In this case, the neon bulb will in fact glow -- not as brightly as when you connect that second lead to the neutral or ground wire, but still plenty bright enough for you to see. (And in fact this effect leads to a useful trick, one I use all the time: determining which of two indistinguishable wires is hot and which is neutral.) The current flow -- if indeed there is any -- is so tiny that you don't feel a thing.
The explanation for why/how this works always involves phrases like "the capacitance of your body", although this has never made perfect sense to me. Steve Summit ( talk) 19:50, 20 November 2005 (UTC)
Is it strange that my CPU is maxing out at 100% when such a large fraction of my RAM remains unused? Causes? Fixes? Perfectly normal? Etc?-- ineedhelp 02:39, 13 November 2005 (UTC)
High CPU usage indicates your computer is carrying out a processor intensive task (of which there are many). Some of these required large amounts of RAM, and some do not. The two resources are orthogonal in that respect. So no, it's not surprising that your CPU is at 100% without a large consumption of RAM. Nor would it be surprising if there was a large consumption of RAM. →Raul654 07:30, 13 November 2005 (UTC)

Say you had a drop of blood and wanted to know whether it came from a man or a woman. How difficult would it be? Would the easiest way be to look for the X or Y chromosomes in the blood cells? Can you even tell X and Y chromosomes apart with an optical microscope? — Keenan Pepper 04:37, 14 November 2005 (UTC)
Well for starters, red blood cells have no nuclei and no chromosomes, so there wouldn't be much in the way of visual clues to sex unless you could pull down their little pants. White blood cells can be stained to show nuclei with Barr bodies under the microscope. A Barr body is a partially inactivated second X chromosome and, though not infallible, is generally a better clue to female gender than a pink hair ribbon. Staining for Barr bodies is old technology however, and if you want something slightly newer and less fallible, you can rely on the good old peripheral blood karyotpe. Perhaps the most up-to-the minute test for sexing blood is detection of the SRY antigen, a pretty reliable indication that the owner also sports a set of testicles. So take your pick. alteripse 05:26, 14 November 2005 (UTC)

The above section named "Some Fundamental Results" in the page "Mathematical Logic" has been changed by the user Otto ter Haar on the 9th of October. The old text read: "Given a first-order formula as its input, the procedure eventually halts if the formula is valid, and runs forever otherwise." The new text reads: "Given a first-order formula as its input, the procedure eventually halts if the formula is valid or not valid, and runs forever otherwise." I do not know or could not find out, what motivated ter Haar to enter this change but it would be an incredible (and unbelievable) result, contradicting all our knowledge of computational theory and computability. The only reason - which I could imagine - to justify this statement, i.e. that there is a theorem prover, which works for valid as well as invalid formulas, is to assume certain finite domains, and do model checking. Nevertheless, this should be somehow included in the modification of this article. Otherwise, it leads to a contradiction with the statement that first-order logic is recursively enumerable (which means all valid formulas can be constructed) and that it is NOT recursive (which means that there is no decision procedure for saying whether a formula is valid or not) - and these two statements are enormously important results for computational theory and are general textbook knowledge. It is also unclear, in what situation the procedure would not terminate - since the modified statement implies that the procedure (the theorem prover) always halts (since in standard logic, there is only true or false). It would be appreciated to get some feedback, especially by ter Haar, on this change and my concerns about it.

Don't forget the other, albeit slower mechanism the eye uses to adapt to darkness-- the synthesis of
rhodopsin in the
rod cells of the
retina. Light exposure depletes rhodopsin from these photoreceptor cells, while darkness permits a metabolic re-stocking of this substance. Actually, full darkness is not necessary in order to replete rhodopsin stores; the rods are insensitive to red light, which permits darkness adaptation with the use of
red adaptation goggles. Using these devices, the eye can continue to function using solely the color-descriminating
cone cells' ability to respond to red light, while the rods adapt to darkness.--

Can anyone help me to get the answer for the question"Can Menstruation will be happend without releasing egg? "
But this is the problem with theoretical answers because the answer is certainly yes. Menstrual bleeding without ovulation is called anovulatory bleeding. It is the most common type of infertility. It characterizes the menses of the first year after menarche in most girls. It characterizes many of the menses as menopause approaches. Women with polycystic ovary syndrome and several other types of hormone imbalances typically have menses despite chronic anovulation. Anovulatory menses are characterized by irregularity, unpredictability, variation of length and heaviness from period to period, lack of mittelschmerz, and lack of premenstrual physical symptoms. Finally, any woman taking birth control pills typically has menses without ovulation. alteripse 11:23, 15 November 2005 (UTC)

RECOGNIZING A STROKE
Thank God for the sense to remember the "3" steps. Read and Learn! Sometimes symptoms of a stroke are difficult to identify.
Unfortunately, the lack of awareness spells disaster. The stroke victim may suffer brain damage when people nearby fail to recognize the symptoms of stroke.
Now doctors say a bystander can recognize a stroke by asking three simple questions:
1. Ask the individual to SMILE. 2. Ask him or her to RAISE BOTH ARMS. 3. Ask the person to SPEAK A SIMPLE SENTENCE (Coherently) (i.e... It is sunny out today)
If he or she has trouble with any of these tasks, call 0-0-0 Immediately and describe the symptoms to the dispatcher.
After discovering that a group of non-medical volunteers could Identify facial weakness, arm weakness and speech problems, researchers urged the general public to learn the three questions.
They presented their conclusions at the American Stroke Association's Annual meeting last February. Widespread use of this test could result in Prompt diagnosis and treatment of the stroke and prevent brain damage.
A cardiologist says if everyone who gets this e-mail sends it to 10 people;you can bet that at least one life will be saved.

Is this correct? - Ta bu shi da yu 01:14, 16 November 2005 (UTC)
It seems like a reasonably reliable screening method for a stroke, but I have trouble imagining a lot of lives saved. For this to actually save a lot of lives, the following facts would need to be true: (1) a large portion of strokes are misinterpreted as something else that does not seem to require urgent care, (2) a large portion of strokes go without early treatment that would lead to a fulller recovery than commonly occurs at present, (3) this screen would lead to an increased proportion of stroke victims getting early care that would produce a better outcome than getting later care. This is not my area of expertise but I suspect all three propositions are somewhat debatable. alteripse 01:24, 16 November 2005 (UTC)
If you know the derivative of a function, then you know the function up to a constant. If you know the gradient of a scalar field, then you know the field up to a constant.

The best explanation I heard for the disappearance of so many ships in this area is that the continental shelf off the coast of America contains a lot of methane gas which is frozen due to the pressure in the deep ocean. The shelf is not hugely steep and if there is an underwater land slide this methane is released as a kind of big Jacuzzi, like swamp gas. (ever stuck a stick in the bottom of a muddy pond and seen bubbles rise up?) Ships cannot float on water full of bubbles and they sink. Others catch fire and sink if the gas is ignited by the ships boilers/electrics. It’s all very local and all very quick. This might explain some of the strange disappearances but not all and I might add that this is just what I read somewhere as a possible explanation for some of the disappearances.-- Eye 23:13, 16 November 2005 (UTC)

Draw two big circles that overlap a bit. (The images at Venn diagram should illustrate this.) Label one circle with the name of one kind of candy (suppose it's "candy A"), and the other circle with the other kind of candy ("candy B").
Write things that are similar between candy A and candy B in the middle section (the intersection of the two circles). Differences should go in the rest of the circle. For example, if candy A is square and candy B is round, you would write "square" in the "candy A" circle, and "round" in the "candy B" circle.

What exactly is a Sugar High if there is such a thing. What is the biology behind it. Doing this for my bio coarse.
A Sugar High is a concept of American folk biology. The concept is that excessive sugar will somehow make someone either "intoxicated" (e.g.,
Twinkie defense) to the point of diminished judgement or responsibility, or in its milder forms, euphoric. Either response of course, puts sugar in the cultural Bad Food category. The first concept is nonsense and the second perhaps has a nidus of scientific fact in the middle of the cultural concretion.
In terms of verifiable science, there are perhaps two relevant phenomena. First, sucrose tastes good, and this taste sensation is strong enough that studies have shown it can be used as an analgesic in infants-- this is part of the basis of the euphoria concept. Second, it is possible to show in animals that high or low dietary carbohydrate intakes produce somewhat differing effects on level of arousal of the autonomic nervous system. Unfortunately for the Sugar High meme, however, the effect of carbohydrates is generally sedating rather than arousing. alteripse 12:21, 17 November 2005 (UTC)

I am trying to relocate a piece of information that I recall reading years ago. It was an article / study that tracked how our eyes commonly move when we are confronted with new information - such as a new package, a new magazine cover, a billboard, a print ad, etc. I seem to remember that the researchers discovered that our eyes commonly move in what I would call a flipped number 6. (Sorry, i am bad a trying to describe spatial stuff - so bear with me) the pattern described was as if the eye were writing a backward "6" - starting at the upper left of the picture, and scanning right and down, and looping back up and to the left - ending at about the center of the item. Can anyone help me validate this? I have tried the following searches - and again - I am a first time user, so I may not be searching effectively: tracking eye movement / how does the eye move when confronted with new information / how does the eye scan a page / etc - and I have had no success so far.
Thank you very much in advance for helping me with this.

The term you're looking for is Eye tracking, here are some related links that I'll add to the article:
- Eyetrack III study
- eyetools study
- ViewPoint EyeTracker software
- Applied Science Laboratories trackers
The first document features something that vaguely looks like an inverted "6". However, it's important to note that the path that the eye takes varies quite a bit depending on what it's looking at. For example, my eyes automatically seek the upper, left-hand corner of an English document; but when confronted with Hebrew, they go to the upper right without any conscious thought on my part. When looking at artwork, my eyes tend to seek out areas of the highest contrast first and then follow contours. These trackers are very useful for determining what people notice in an advertisement, which things are distracting, and which elements are overlooked. Lastly, you did a great job asking the question. Cheers! -- Avijja 07:57, 18 November 2005 (UTC)

The uninsulated tank is cylindrical, 9 metres in length and 2 metres diameter and has a external surface area of 69m² The tank is constructed from 3mm thick 304 grade stainless steel which has a thermal conductivity, k, of 16.2W/m.°C There is 30,000kgs of liquid product inside the tank with a specific heat capacity of 3.9kJ/kg.°C
The product temperature is 5°C, the ambient temperature is 25°C
What will be the rate of temperature increase for the product in the uninsulated tank?
The insulated tank is the same tank as above but is insulated with a 70mm thick polystyrene external layer surrounded by a 0.7mm thick stainless steel cladding panels.
The polystyrene has a thermal conductivity, k, of 0.038W/m.°C
What will be the rate of temperature increase for the product in the insulated tank? 213.218.255.233 14:14, 17 November 2005 (UTC)
Is it better to set the temperature low when the house is unoccupied? The furnace then runs longer to raise it to a comfortable temp. when programmed to come on. Or is it better to maintain a more moderate temp. with the furnace only coming on periodically to maintain it? Also, does it use much more gas to maintain it at 70 degrees F as opposed to 65 degrees? (Note: Thermostat has available 4 changes for Mon - Fri and two for Sat-Sun)

I would like to know if Familial Alzheimer disease is a spontaneous mutation, and if so what fixes the mutant allele in the population? I read a research article that refered to the allele as a "private mutation", occuring only in idividual families excluding non relatives. Is a private mutation the same as a spontaneous mutation.-- 131.204.83.180 17:40, 17 November 2005 (UTC)
Our article on Familial Alzheimer disease should anwser your question. The condition is inhereted in an autosomal dominant pattern, which means that only one parent needs to have an inhereted or spontaneously mutated gene associated with FAD for the condition to be passed on, thus with about ~50% chance of the offspring getting a mutant copy of the gene, the disease then has a pretty good chance of becoming fixed in the population. I haven't come across the term "private mutation" before, but often papers focus on a particular family and this term might be being applied to the specific muation in one of the FAD associated genes common in that family.-- nixie 03:39, 18 November 2005 (UTC)
what is the role of a chemical engineer in nanotechnology.
Nanotech, as you probably know, is the science of making REALLY small things. A chemical engineer working for nanotech, therefore, focuses on making very small but useful molecules. Examples include carbon rods and "buckyballs", or buckminsterfullerene. These molecules can be used to help develop nanorobots, as the structures developed lend strength to the tiny machines.

What is the theory of Matter? Can u summarize it for me please?
The basic idea is that ordinary matter is composed of isotopes of the elements in the periodic table and ions of those atoms. Note that this excludes matter in nuetron stars, black holes, and some other special cases. These atoms are in turn made of protons, nuetrons, and electrons, which are in turn composed of quarks, which are in turn made of strings, etc. StuRat 15:17, 19 November 2005 (UTC)

1. Is light a continuous stream of photons? If so, light traveling from a distant star must connect the observer with the past in a very real way. In other words, along that continuous stream of photons some photons actually belong to part of the stream that is thousands of years older than other parts of the stream. How can such a structure exist? This stream of photons not only crosses vast distances of space, but also of time -- yet it remains a single unified structure that can carry a continous stream of information. Gary O-- 65.66.151.189 04:06, 18 November 2005 (UTC)
Going back to the original question: think about a snapshot photograph of a stream of water coming from a water hose and that the stream is an entity of water molecules being emitted from that hose. The water molecules at the end of the stream furthest from the hose are older than the water molecules that have just come out of the hose. Now go to live action: watch as the hose is modulated (wiggled around) and watch that information travel in time to the end of the stream. I think that's the concept you are trying to capture. As always, analogies eventually fail so don't take this water stuff too far. :-) -- hydnjo talk 02:21, 19 November 2005 (UTC)

I am trying to remember the name of a phenomenon. While touring a nuclear reactor, I remember looking into one of the cooling pools and seeing the core (or rather what one can see of the core, as it is not the core itself, obviously). There was a blue light emanating from it and I asked my dad about it. My recollection of what precisely is fuzzy (hence my desire to remember the name), but it seemed that the light was a result of super-excited particles tearing out faster than the speed of light (in water) and reacting with the water, creating the eery blue light. I recall stumbling upon the name and I believe it was Something Effect (imagine that), something being the actual name. I believe it started with an M, but I'm not certain. If someone knows the name that would be of great help, then I could read about it again.

Okay, it's getting to be the time of year for cold weather, fleece jackets and static electricity. So here's a question that's baffled me for a while.
Suppose my jacket has acquired a lot of static charge. If I am holding or wearing the jacket and I touch something metal and grounded, I get a bit of a shock. But if I take the jacket off and touch something metal and grounded through it - so here the fleece and the metal are in contact, and my finger is not between them - I get a much larger shock.
The explanation I had thought of was that the more direct contact between the fleece and the metal meant there was less resistance for the static discharge, resulting in a stronger spark, and my finger would still be next to the spark and feel it.
But here's the weird thing. Suppose I take the jacket off and put it over the back of a chair with a metal frame, without touching the frame. There's no static discharge. But if I then touch the frame through the jacket, then I get a big static shock (and the fleece becomes much less staticky). Why does that happen? Why won't it discharge until my finger is there?

Dear sir, i have the problem regarding the swelling around both ear at the lateral part of the ear i meet to some doctor to reduce that swelling ,but it goes invain due to such swellin on the face face seem to very eagly,
some doctor told it is the excessive growth of the saliva gland ,i dont know what is the actual reason behind the but it is not due to the obesity,the inflamation like the growth of laterl part of chick under ear and around the ear and on the jaw ,please sugget the remady on this thanks
It would be helpful to know precisely where the swelling is. For example, swelling of the external ear, or pinna, presents a completely different problem than swelling of the parotid gland or the angles of the mandible.
Assuming your doctor is correct in that the swelling is located in the parotid gland, the problem could be any of a number of things: viral parotitis ( mumps), autoimmune disease such as Sjögren's syndrome or Miculicz syndrome. An important criterion for diagnosis would include the time line of symptoms-- i.e., how suddenly the swelling appeared, and how long was its duration.
In any case, you might want to prevail on your doctor to provide more information, or to refer you to a facility or another doctor that can. Some of these conditions are not trivial, and their significance to health goes beyond simply being a cosmetic liability. --

How does one calculate the pH of a solution when a weak acid is added to a weak base? How does the method differ to weak base and strong acid etc. Is it acid specific?
Such a question is off the specification for my Chemistry course, the teacher didn't know so I'm interested!
---DK
The general solution for the case of a weak acid/weak base leads to a cubic equation for the hydrogen ion concentration, which is obviously not simple to resolve. In general, weak acid/weak base titrations are impossible to perform with a coloured indicator or a pH meter, although they are sometimes possible by conductimetry. This is probably why they are not on your course specification. Physchim62 (talk) 07:05, 22 November 2005 (UTC)

It rings of a bell, but I can't remember at the moment; what it probably does is try to make "holes" in the walls between the matrix and intermembrane space of the mitochrondria, that way, energy production from glucose is less efficient, ie. instead of 36-38 ATP per glucose molecule, it is 20+ or even less or something. Hence, you burn more food/glucose (and fat which is converted to glucose) for the same amount of activity. This is dangerous of course, because if it ends up being that it takes more energy to metabolize food than it produces, then you have an energy loss just by thinking or breathing, rather than merely slowing down energy production. I've come across the article before. This should lead someone else in the right direction. -- Natalinasmpf 21:16, 20 November 2005 (UTC)

Does anybody have any good references for the "computational model" underlying entertainment DVDs? There's quite a bit of variation in the way the scene selection and other menus work, and in the kind of effects that can accompany the special features. It seems that each DVD's menu tree must, in effect, be written in some kind of programmng language, but obviously one that is ultimately represented in some nicely device-independent form, since the DVD's can not only be played on general-purpose computers (both PC's and Macs) but also of course on dedicated, single-purpose DVD players. I'm curious to know what the specification of that "programming language" is, and what features it supports.

Hi. I read a while ago that an array of photovoltaic solar panels 100 miles square in the Nevada desert or Arizona would generate enough electricity to meet all USA power needs. My question is how much would this cost (& how does this compare to the total cost of a nuclear power plant - including decomissioning cost & storage of radioactive material, etc). I'd assume that the solar array would need to be raised off the ground (say enough to allow a car to drive under it) for maintenance & that the solar panels should tilt (both to catch the sun better & to knock off any dust/sand that blew onto them) so some engineering cost would be needed as well as the costs of the panels.

Don't think theres any special name. Removing the rationals from the real number line turns it into a "fat" cantor set.

The M3 Lee is a World War II tank with a 51 mm front armor made of ordinary steel. If a modern M1A2 tank fires a round of 120 mm armour-piercing fin-stabilized discarding sabot ( APFSDS) at it at close range, would the depleted uranium kinetic energy penetrator fly straight through it from head to tail?
Since the M3's steel armor is not too slanted, the effective thickness of armor cannot be too thick. I think many modern penetrator can easily 500 mm.
Then how about a 75 mm thick M4 Sherman or an 180 mm thick Patton tank if you only have steel plates?
Can several modern tanks sink a heavily armored WW2 main battleship if the ship stays within their effective firing range? I mean you can aim at a point slightly below its water line. And if a tank cannot destroy all watertight compartments, several tanks may carry the required amount of ammunition. -- Toytoy 16:56, 21 November 2005 (UTC)

It is debated whether T. rex was warm or cold blooded, and no definitive evidence exists to disprove either argument.

What is the storage location and adress (computer related)
The location in memory where a byte of information is stored is described by a number (the address of that memory location). For example, if your name was stored in the computer, it could be written at the very beginning of memory, which would be bit 1 (or bit 0, if they start counting at 0 instead of 1, as they often do in computers). Depending on the length of your name, the next available address in memory might be, say, 30 bytes later. Note that they tend to use hexadecimal numbering, with leading zeroes, to describe memory addresses, as shown below. Thus the next address in memory might be 000000001E:
Decimal Hexadecimal ======= =========== 0 0000000000 1 0000000001 2 0000000002 3 0000000003 4 0000000004 5 0000000005 6 0000000006 7 0000000007 8 0000000008 9 0000000009 10 000000000A 11 000000000B 12 000000000C 13 000000000D 14 000000000E 15 000000000F 16 0000000010 17 0000000011 18 0000000012 19 0000000013 20 0000000014 21 0000000015 22 0000000016 23 0000000017 24 0000000018 25 0000000019 26 000000001A 27 000000001B 28 000000001C 29 000000001D 30 000000001E
Another form of memory address is memory offsets (relative addresses) where the amount to add to a fixed reference address is given, rather than the absolute address. Virtual memory takes this further, and uses a program that figures out where to actually store the data, regardless of the memory address you specify. It uses a look-up table to match the addresses you specify with the real addresses. In most modern programming languages you can, but don't need to, specify memory addresses. Whenever you declare and assign a variable, like X=5, the system figures out a place to store that automatically. The most common place a user will see an address is in an error message, something like "Memory overflow at address...". StuRat 19:35, 22 November 2005 (UTC)
I'm trying to back up my digital photos on CD-Rs. The .jpg files average about 1.4 MB in size. The capacity of the CD-Rs is 700 MB, thus I figure I should be able to fit 500 photos on a disk.

How does sodium carbonate remove stains from laundry?
For example, an oil stained piece of clothing is soaked in a solution of sodium carbonate and water. Thanks--Curious Person
Why Did Sodium Carbonate (Washing Soda) Dissolve an Oil Stain Thank you for your prompt answer concerning Sodium Carbonate as a stain remover ( "Arm and Hammer's Washing Soda" was used to remove an oil stain without detergent, just soaked in hot water and Arm and Hammer).
The answer mentioned that ..."It softens water by binding to dissolved calcium and magnesium—in hard water detergent molecules tend to bind to those dissolved metals instead of to oil and dirt. Sodium carbonate is also a weak base; in some cases this can increase the solubility of stains in the wash water, removing them from clothing..."
If the water was "soft," and the water did not have to be be softened by binding to as many dissolved calcium and magnesium molecules, would the base of sodium carbonate be able to attack the stain by increasing the solubility of the stain since it was not softening the water as much.
Thanks again. --Curious Person

Hi. I'm doing a project for science and our unit right now is heat. My partner and I have to research about easy bake ovens. First off, we have to discuss the kinetic molecular theory (KMT), temperature, and heat of the easy bake ovens in terms of Q=MC and/or energy for the phase changes. Next, we have to identify where the 3 heat transfers (radiation, conduction, and convection) occur during the process of using the easy bake oven, and then have to apply Newton's law of cooling (Q/T=K (T1-T2)) to it. Lastly, we have to apply the first and second law of thermodynamics to the easy bake oven. All in all, my question is if you could help me gather this information or direct me to some usefull sites of where i could find this information? Please and Thank you.

I am a novice with chemistry, however, I am working on a project whereby I would like to identify a chemical or combination of chemical substances that when combined (mixed) with water will generate a chemical exothermic reaction that will produce extreme heat up to 661 degrees centigrade (melting point of aluminium). Optimally, the process of this reaction would vaporize the reactants, leaving little or no trace elements of the chemicals used and / or the resulting residual chemicals are environmentally friendly (are not pollutants of water or air). And No, I am not building a bomb. The result I hope to achieve is to come up with a relatively inexpensive method of breaking the molecular bonds of a material that could be coated with this chemical substance. After coating the material, the introduction of water would create the desired reaction.

How would I calculate the mean current flow when a capacitor is discharging? I have been given the time it takes for this to happen, and I've calculated capacitance previously, having been given the p.d., area of a plate and distance etc.

Also can you confirm that I am right in thinking that there is no change in p.d. where two plates are moved further apart while a battery is still connected, and capacitance decreases, so does charge on each plate and therefore energy?

Is water the only liquid that expands when frozen--````````
Arguably no. It is probably only the common one that does, although I think you could come up with another molecule with the intention of having it so. The reason is the fact that in the solid state the water molecules in order to be bonded into a "frozen, vibrating" kind of state, there's a lot of space between the molecules because well, the molecule is like a three-pronged star, and there's a lot of empty space between the molecules despite the fact that the molecules don't move a lot (the "prongs", that is the different component atoms are however due to their charge bonding each other in place)...a bit of a rough and messy description, so bear with me. Other materials don't have quite that structure so that might not happen because when the temperature drops and the molecules don't move as much, less space is wasted. Somebody more skilled should help you here, but I just was wondering if the three-component structure of carbon dioxide has anything to do with it's sublimation properties (ie. dry ice et al)....possibly you could also have a triangular protein... -- Natalinasmpf 23:37, 24 November 2005 (UTC)

Hi
Is there such a thing as the geographic centre of the world? If so where?
If you think 3-dimensionally, the world certainly has a geographical center: it's about 4,000 miles straight down from wherever you may be (assuming you're not reading Wikipedia from outer space). The Earth is a sphere, or more precisely an oblate spheroid, so it has a center. You just won't find it on a map of the Earth's surface.
Perhaps a more interesting idea is the geographical center of all land on the Earth's surface. I think the right way to compute this is to first take the average position in 3-dimensional space of all points of land on the Earth's surface (this will be a point deep inside the Earth, but not at the center), then use the point on the surface directly above this point. I happen to have at hand a suitable data set whose origin I was not told, and have been meaning to program this computation on it for ages... okay, done. If I got it right, the center is 44.50° north, 28.23° east, which is in eastern Romania near Constanta.
Another interpretation is given on this web page: the geographical center of the world's land area is defined there as (in effect) the point that minimizes the average great-circle distance of all land from it. The author of the web page computes this as 37.688° north, 35.438° east, which is in south-central Turkey. The web page states the position to be near Iskenderun, but actually it is closer to Adana.

I just saw that episode of Seinfeld where Jerry and Kramer are watching an operation and a Junior Mint falls and lands inside the incision. Has something like that ever actually happened? What would happen to the patient in that circumstance? Would he get an infection from the non-sterile mint? — Keenan Pepper 01:00, 26 November 2005 (UTC)
Although there have been so many million operations in so many places and circumstances over the last 2 centuries, it is hard to say never, it is extremely unlikely. The trend has been to use smaller and smaller incisions over the last 2 decades, so that few operations involve large areas of open exposure. Overhead observation "bleachers" have not been used for decades in the US. I havent seen the episode but assume from your description that they were observing from an old fashioned elevated observation gallery rather than standing in the OR. No one observng in the OR gets anywhere near the incision because there simply isn't room between the surgeon, a resident, a scrub nurse, and usually more bodies than that. Theoretically the lodging of an unseen piece of candy would result in a foreign body reaction, probably with a local infection and abscess. The problem is that it would be hard to see the problem by x-ray. alteripse 03:08, 26 November 2005 (UTC)

There is much evidence for floods in the distant past (maybe even a few thousand years ago). See Deluge (prehistoric). However, there is no evidence apart from scripture or myths that a single worldwide flood occurred and acted as an evolutionary bottleneck, destroying all humans or animals except those on an ark. There is much evidence that large numbers of people and animals have been in various parts of the world for more than 6000 years. There is also some evidence that some organisms have changed during that time.

I've recently been playing around with a nuclear weapons effects calculator based on the one at the following URL: http://www.stardestroyer.net/Empire/Science/Nuke.html
If I put in yields of say, 15 kt or 1 Mt, it comes out just as one would expect in terms of the order of the width of the effects: 1. fireball is smallest, then 2. air blast/near total fatalities, then 3. ionizing radiation, then 4. air blast/structural damage, then lastly 5. thermal radiation has the widest reach. However for very small blasts, say, 1 kt / 0.001 Mt, the order is different: 1. fireball, 2. airblast/near total fatalities, 3. thermal radiation, 4. air blast/structural, 5. ionizing radiation.
That is, the ionizing radiation and the thermal radiation have changed positions. Is this an artifact of the calculations (made for larger rather than smaller explosions), or would this make sense from a physics point of view? -- Fastfission 18:38, 27 November 2005 (UTC)

Thank you for your prompt answer concerning Sodium Carbonate as a stain remover ( "Arm and Hammer's Washing Soda" was used to remove an oil stain without detergent, just soaked in hot water and Arm and Hammer).
The answer mentioned that ..."It softens water by binding to dissolved calcium and magnesium—in hard water detergent molecules tend to bind to those dissolved metals instead of to oil and dirt. Sodium carbonate is also a weak base; in some cases this can increase the solubility of stains in the wash water, removing them from clothing..."
If the water was "soft," and the water did not have to be be softened by binding to as many dissolved calcium and magnesium molecules, would the base of sodium carbonate be able to attack the stain by increasing the solubility of the stain since it was not softening the water as much.
Thanks again. --Curious Person

I was reading the article about diabetes and one question came up. I`d know why non-diabetics can not use `artificial` insulin to the day-to-day living.So, doing that they would use less of their own, `natural` insulin and their bodies would not be overcharged by a big amount of glucose that they ingest. So , non-diabetics could prevent the disease . For example , a non-diabetic person that eats to much carbs (glucose) per day is increasing their risk to get the disease , because they overloaded their organism with a big amount of sugar that their body cannot handle 100%. But , if that same person ingest the same amount of sugar and use an `artificial` insulin for that , their body would not have to use their insulin , not overloading the body , and for consequence , not causing diabetes .

Interesting question and not as crazy as it might seem at first look to some. For the purposes of this answer let's restrict it to type 2 and let's use the common simplified story that the following sequence of stages happen as someone slowly develops type 2.
Now the above is perhaps oversimplified and we do not understand all the details of all the steps and there may be other routes to type 2 diabetes.
However, let's get back to your question. We have fairly strong evidence that doing something at stage 3 to reduce hyperglycemia or pancreatic damage may prevent the irreversible death of the beta cells. At stage 3 the person does not technically have diabetes, but can be said to be "prediabetic". This is when exogenous insulin injections might spare the person's beta cells from exhaustion and hyperglycemic damage. So what would be down side to your idea?
So the answer to your question is: I can imagine a situation where that might be a prudent thing to do. Is that what you had in mind? alteripse 03:26, 29 November 2005 (UTC)

Hi, I own a MSN(nee WEB)TV. It has a browser and email and it is fine for home, but, I have little knowledge of deep computer running details. At work, late at night, I have used the company computer to go to Google and Yahoo and on occasion gone to -Adult- sites. I know how to "clear Google history". I know how to use "tools" to delete "recent history". But.. tonight I discovered "internet options" in "control panel" in "my computer" on the desktop and saw a _lot_ of 'incriminating' temporary internet files. Some were very easy to identify and others were either Spyware I attracted (edge.ru4.com, ad.doubleclick.net, etc) or anti-adware that I should leave alone.
I went to Google with some terms and addresses which sent me to computer (self named) Geek forums which listed the few I have cited here. A few were a bit hard to follow as there were lists of "antispyware programs" that looked a tad like the FORTRAN they tried to teach me in 1969. 8-)
Finally, the point and question: is "Akamai.net" one of the 'good guys'? How about "a.as-usfalkag.net"? I was able to help myself by hi-lighting something and clicking on "properties" and anything with a "last [adjusted] date" that was a year or more old was something to keep and anything with today's date and no other info was 'bad'. Some of the 'bad' had today's or tomorrow's date to 'expire' and some had 'none' as a date.
Is my only opton to go through each and every one that happened on my shift and check 'properties'? Google and Yahoo in general aren't bad, but, they may have a link to my 'indiscrection' and should not be kept. Some 'cookies' to Yahoo may be needed and some files are jus on how to make the page look right (I think!)

Hi, Thank you all for the info. I would 'view' at work and 'go to' at home. (WEBTV is a big computer in California and I an in (another state) with a browser and email dialed-up and converted to show on a TV screen.)Are you saying that if I deleted all temp internet files, reaching a site might be a tad slower but still act normal? Some seem to be gifs and jpegs for the (company's) main page and link to my email, etc. and some have specific expiration dates in the future. Possibly the latter are anti-spyware, etc that some one took time to save in this "temp" folder.
Am I safest (for the correct running of programs, not just getting caught) going thru and deleting one at a time anything that has no real 'Properties'. Were the two files mentioned in the original (Akamai.net and a.as-usfalkag.net) 'good guys', ie: anti-'bad guy' stuff? My looking on the net was a bit confusing for those two. I want to make it easy for the computer to do what it must and not remove anything someone actively looked for to have as a anti-bad guy tool.
If I am looking at a desk top that needed no password to access, is the "My Computer" for that station only or for many? Is the one station that needs my pasword unaffected by these files? My MSN (WEB)TV takes up enough of my time and becoming more computer literate beyond the scope of what I need to know at work, where they will train me in 'how to' and not 'how it did that' is not a high priority.

I've been trying to express pi as the limit as n goes to infinity, where n is the number of sides in a polygon. From what I've figured, it would be the ratio of the perimiter to the length of the longest diagonal. However, as I haven't used geometry for several years, I can't seem to express it mathematically. Please help and explain when neccessary. Thank you. -- frenchman113
First of all, I won't use diameter, because most polygons don't really have well-defined diameters. Even with regular polygons, if the number of sides is odd, diameters are tricky because they go from vertex to side, rather than vertex to vertex. I'll use a radius r instead (defined to be the length from the center to a vertex). So, for a regular polygon with n sides, each side of length s is subtended by an angle of
since there are n equal such angles. Using the law of cosines, the length s is given by
Solving and simplifying gives
The total perimeter of the polygon is Pins=ns. I may then consider the ratio Pins/2r:
This formula gives a lower bound for π, since it applies to a polygon inscribed in a circle (which has a shorter perimeter than the circle). If I consider a circle circumscribed by a polygon, using similar methods, I get
Thus I conclude that
and that
You can use this formula to get approximations of π using the half angle formulas. I believe that this is the method that Archimedes used. Hope that helps. - lethe talk 23:34, 29 November 2005 (UTC)
Have any neurological diseases (similar to Huntington's, Alzheimer's, or ALS) ever been cured?
Marianne
18:59, 29 November 2005 (UTC)
Most progressive neurological diseases are considered "incurable" due to either the limited ability of
neurons to repair themselves, or limited knowledge of the pathogenesis of these diseases. The closest thing to a cure I can cite is the limited success in treating
Parkinson's disease with the implantation of fetal
stem cells. The fact that this has happened at all is perhaps due to the relatively extensive knowledge of the biochemical basis for the symptoms of this disorder. See:
Fetal Brain Cell Transplants Benefit Some Patients with Parkinson's. Of course, the issue of fetal stem cell use is rife with ethical and religious questions, which will probably limit the usefulness of this method as a means of dealing with neurological disorders on a wide scale.

Electrically, what is the difference between an earth ground line and a neutral line in standard US utility systems? I ask because I am working with a 120VAC switching power supply that outputs 24VDC on one line and ground on the other, and a device I am using still requires a separate earth ground. The mfr even went so far as to design the supply to obstruct the ground pin on the outlet so it could not be used for this purpose. It was my understanding that the ground line and the neutral line were ultimately tied to the same place (a true earth ground like a copper pipe emerging from underground), and extend outward separately in the utility network as a safety mechanism, the ground being for device faults to shock the utility and not the user. If this is true, why do I not get +24V when measuring from the positive on the power supply to the earth ground line? Is this a sign of a bad ground? -- Jmeden2000 22:47, 29 November 2005 (UTC)

How would one go about calculating how long an orbit would be for a star with a different mass than the Sun? Is it as simple as if the sun had half the mass, a year would be twice as long? What about if the planet had a deferent mass? Would a planet with three quarters the mass of earth orbiting a star with half the mass of the sun at 1 AU have an orbit 2.7 years long?

What types of flexible matierials block EMR (i.e., mesh, aluminum, kevlar)?
Thank you. Crillion 14:15, 30 November 2005 (UTC)
Here is the answer to the second question. Wire meshes are effective materials which shield objects from EMR. When an object is enclosed by a wire mesh or is inside a metal box(which can be of aluminium foil), electromagnetic waves cannot enter the mesh or the box. This can be easily observed. If you wrap your cell phone in a wire mesh, you can see the signal gradually decreasing in strength and eventually dying out. This is the technology used in coaxial cables used in short range communication to prevent external disturbances. Of course, wire meshes can not shield against EMR of high frequency such as light but is effective in the radio frequency range. When a source of electromagnetic radiation is enclosed in a wire mesh, there is no obstruction to the outgoing EMR. Vishnu Pradhan.V 17:57, 30 November 2005 (UTC)

WHAT IS RED HAT ENTERPRISE AND WHY IS IT AN OPTION
WHAT IS RED HAT ENTERPRISE LINUX?
Space craft that go beyond Mars are quite often accelerated using a sling shot effect, by passing close by some heavenly body. Of course they will get accelerated when they approach it, but after that they have to escape the gravitational pull to continue, which would annihilate the effect. So how does this work? I imagine it has something to do with either the change in direction or approaching the planet (or whatever) 'from behind' (relative to its motion), thus not using the gravitational pull but the speed of the planet.

There are three types of orbital motion, parabolic, (ballistic trajectory) elliptical, and hyperbolic. By approaching a planet in a hyberbolic orbit, we don't accelerate from the gravity of the planet, but we acquire the velocity or twice the velocity of the planet's motion. If the planet was stationary, all we would do is change direction. Since the planet is moving, we acquire the velocity of the planet while accelerating around it in the hyperbolic orbit. A good explanation is here. [2] Dominick (ŤαĿĶ) 12:48, 1 November 2005 (UTC)
The key is that the spacecraft steals some angular momentum from the planet. Since the planet is so much bigger than the spacecraft, the planet's speed changes negligibly, but the spacecraft gets a big boost. If the planet were stationary than the trick would only change the spacecraft's direction. — Laura Scudder | Talk 16:37, 1 November 2005 (UTC)
The trick to thinking of this situation easily is to use frames of reference. Imagine you are standing on a road, looking south, and a car comes toward you at a speed of 50 (mph or km/h, whatever units they use where you live). You throw a ball directly toward the front of the car, at a speed of 40, and step out of the way. They are closing at a relative speed of 90... that is, in the car's frame of reference, the ball is moving south at a speed of 90. We assume that the car and the ball are perfectly elastic bodies, that is, the ball does not waste energy in denting the car or anything like that. Then the ball will bounce back from the car at a speed of 90 in the opposite direction, north. But that's 90 relative to the car... so in your frame of reference it's now going at 140! Don't try this at home!
Now consider the same situation, only this time you turn away from the car and throw the ball north at a speed of 20 (before stepping aside), so that the car catches up with it. The car is moving north at 50, so in the car's frame of reference the ball is moving south at 30. Hitting the car, it bounces north at 30 in the car's frame of reference... which is 80 in yours. Same idea as the first experiment, although the speed change is less dramatic in this case.
In both cases, if you measure closely you will find that the car has slowed a little, as the ball stole some of its momentum. This shows up as a change in the speeds of the two frames of reference relative to each other. But for purposes of understanding the experiment, this can be pretty much ignored.
The car example is one-dimensional. For planets and spacecraft, you have to think in at least two dimensions. Here is how it looks in the planet's frame of reference: The spacecraft approaches from a distance and falls toward the planet on an off-center path. The planet's gravity causes it to follow a hyperbolic orbit. The symmetry of this shape means that the spacecraft departs at the same speed as it was approaching originally, but in a different direction. The effect is very much as if the spacecraft had simply bounced off the planet, even though it is being pulled by the planet's gravity, and not pushed by the (electromagnetic) forces involved in bouncing a ball.
Okay now, in your frame of reference, the planet is moving along its orbit. For simplicity, say it comes up almost directly behind she spacecraft, like the second car/ball example. Then in your frame of reference, the spacecraft may end up moving in very much the same direction as before, but considerably faster. The details of the before and after directions are actually more complicated and not the sort of thing you can do in your head; for one thing, it depends on how close the spacecraft comes to the planet. But this gives the general idea.
(Typically the planet and spacecraft will be moving in the same direction, like the second car example; this is because the Earth's own orbit, which is also in the same direction, determines which orbits can be reached at reasonable cost.)
You asked if it is "not using the gravitational pull but the speed of the planet". You should now see that it is using the gravitational pull in order to use the speed of the planet. It has stolen a tiny bit of momentum from the planet (and, in the same interaction, some of its angular momentum as well).

The horizontal line might indeed be called a vinculum, but normally that word refers to a similar line with other meanings. But as to the parenthesis... in Florian Cajori's A History of Mathematical Notations it is called a lunar sign. Sometimes in short division the quotient is placed to the right and set off by a left parenthesis, like this: 16)512(32.

What is the scientific reason behind the fact that the number of columns of seeds in a corn cob is always even ?
I'm not sure, but I would guess that it is due to nature's preference for bilateral symmetry. This is a handy trick for reducing the number of instructions required to "build" and organism. A bilatrally symmetric corn cob will always have an even number of seed rows, because the instruction is (basically) "build one seed row on each side".

"In mathematics, a fullerene is a trivalent convex polyhedron with pentagonal and hexagonal faces. Using Euler formula, one can easily prove that there are exactly 12 pentagons in a fullerene.

For instance, there are 1812 non-isomorphic fullerenes C60 but only one of them, the buckminsterfullerene alias truncated icosahedron, has no pair of adjacent pentagons."

I just read an article concerning the possible discovery of a supermassive blackhole at the center of our galaxy. And that sparked my curiosity about wether our galaxy is expanding or contracting?
I know that all galaxies of the universe are moving away from each other, Expanding, at equal speeds, and that as a whole the universe is in fact expanding. But then there are blackholes, such as at the center of our galaxy, that are so dense with matter that the gravitational force is pulling in surrounding planets and stars like a cosmic whirpool. This would be a form of galactic contraction, right?
Also where does the matter and energy go? Scientists say that it completely disappears, because no light can escape a blackhole. Could these be the sites of new universes, turning the dimensions inside out to create new alternate, and invisible (to us) worlds?
I would enjoy any guesses or information you may have.
thanks- brian
Just to simplify the answers on black holes affecting expansion or contraction of the universe...as massive as black holes in the center of galaxies may be, they are a tiny portion of all the mass in the universe, and thus don't have much effect on the expansion or contraction of the universe. Also, whether the mass was evenly distributed or in a series of black holes might not make much difference in the calculations, if the total mass is the same. The oddest thing about the expansion of the universe, is that it seems to be expanding at an ever increasing rate. This requires some exotic theories to explain. StuRat 05:17, 4 November 2005 (UTC)
Fred’s contribution to cosmology is what he was best known for by the general public. In 1948 he, and Bondi and Gold, in two separate papers (Hoyle 1948; Bondi and Gold 1948), put forward the idea that the Universe is in a steady state. Fred’s contribution was the introduction of an extra term Cµν into the Einstein field equations. This extra term represents the creation of matter. At least initially the form in which matter was created was not specified, although of course it had to be electrically neutral. More recent theory, which explains the isotropy and homogeneity of the Universe, namely the ‘inflation’ theory, has a metric which is identical to that of the C -field cosmology.
Regardless of the presence of a black hole at the center of our Galaxy, both the Universe ( everything we detect ), and our local cluster ( us, and nearby galaxies), and us ( the Milky Way Galaxy ) is expanding, evidensed by the observation of the redshift. ( light emissions shifted toward longer red wavelengths due to doppler shift ). The cosmological question is what will the end look like, and gives rise to 3 1/2 theories:
Note: This is an extrodinary refrence: [ Cosmology FAQ ]
"Tell your Congressman and Senators to support astrophysics research at NASA, NSF, and DOE."
"The original S-S universe and its more recent successors all posit a universe that is infinite in extent. The expansion everywhere is compensated by episodes of creation (mini bangs in recent models) so as to maintain an overall SS state. The velocity of light is constant."

So I learned the hard way that std::vector containers may internally resize and "reorganize" during execution of your program, meaning that if you have a container of objects, you aren't guaranteed that, &mycontainer[53] will always equal the same reference address.
I've pretty much figured out a solid configuration to set up geometric mesh structures but certain things I didn't know about the STL (not really having used it often) is making the actual implementation a bit of a pain to make it fast and relatively free of fatal bugs. For meshes with efficient operations, I need to use a more memory-reliable(?) container, where &mycontainer[53] will always equal the same memory address regardless of whether that container has 60 items, or 600,000 items.
STL documentation doesn't really explain the nitty-gritty internals of how these containers function behind-the-curtains so I'm a bit hesitant to just change my program by a kneejerk reaction and jump on any other of the STL containers. What's the most "safe" C++ STL container to use, if any, that still allows for constant-time O(1) lookups (even O(log n) isn't acceptable for meshes with hundreds of thousands of vertices and polygons meant to be rendered many dozen times per second) and, most importantly, guarantees every object in it will always have the same memory address that it did when you first inserted it any time ago?
Also, on a somewhat related note, if there are any math-dummy-friendly books by reputable authors about implementing graphics structures in C or C++ that anyone could recommend I'd appreciate it greatly. I understand meshes but I also intend on allowing animation and deformation when I get this current mess sorted out, but vertex-deformation weighted and hierarchal IK animation seems a bit scary to me -- plus, practicing this with trial and error, I could just as well be currently doing some other faux pas I'm not conscious of. -- I am not good at running 22:00, 4 November 2005 (UTC)

Why and how does a decay of a neutron give rise to a neutrino and an electron? I see in the first place that since neutrinos and electrons aren't part of quarks at all, how does the release of them somehow change one of the down quarks into an up quark, seeing that quarks are fundamental particles and aren't composed of neutrinos or electrons. Is this something relating with E=mc², where one of the quarks get turned into pure energy, and is reformed into a new quark? And in order to comply with the laws of conservation, would it suggest some quarks have more energy than other quarks, or is this relative to their arrangement depending on what type of quarks there are in a given moment? Two down quarks and one up quark after all, seem to have more energy than one down quark and two up quarks, since the former can produce the same thing PLUS a neutrino and an electron? And since overall, it bears the material that has the abilities of both proton and electron, why is this not exercised in the atom, affecting proton/electron number, etc.? -- Natalinasmpf 12:20, 5 November 2005 (UTC)

As for the question of two up and one down having more energy than one up and two down : You can't divide the energy up among the quarks only like this. There are a lot of gluons involved. The energy for the beta decay of one quark comes from the whole system of the three quarks plus all the gluons, not from the quark that decays.

Why do light rays/beams travel in straight lines???
A single application of a force makes something travel in a straight line. Add another force is when you get a curve. Light is driven by one force (to roughly but technically incorrectly describe it)....only when you add another force, like a mirror, or gravity (for example the electrons in the silver molecules of the mirror apply an additional force to the light waves) that the path changes. When you throw a curveball for example, your muscles are applying at least two different directions of force. -- Natalinasmpf 19:42, 5 November 2005 (UTC)
I would ask you to repeat a thought experment. When asked by reporters how Einstien came up with Relitivity, he said 'What would I see if I rode on a beam of light?' Lets see if we can recreate what he saw. (Keep in mind that a frame of refrence is consistant. Right angles are right angles ). A beam of light in a vacuum would travel at the limit of speed. Nothing could travel faster. If it was traveling near a large mass, the local frame of refrence would curve and the light beam would continue straight through it, but to an outside observer( remote frame of refrence, the light beam would appear to bend, but it according to General Relitivity, it wouldnt. Again, its the local frame of refrence that although consistant with itself, would appear to a remote frame of refrence as bending. Artoftransformation 23:48, 5 November 2005 (UTC)
Just a thought with no basis whatsoever (and an attempt at that 'extraordinary simplicity'). Isn't a straight line defined by how light travels? DirkvdM 16:48, 6 November 2005 (UTC)

Suppose I have a ball of some mysterious substance that is unaffected by any force - especially gravity and electromagnetic forces. If I let go of this ball (of course, it would be hard to hold in the first place), what would happen to it? Would it move relative to me? Where would it go?-- Fangz 17:02, 5 November 2005 (UTC)
The way I see it: of course, it would be hard to hold in the first place. No, you just WOULDN'T be able to hold it at all, because you'd NEED to use a force on the object for this. Since sub-atomical electrical forces is what makes you hit a wall, and not go through it, such substance would just go through everything. But it doesn't stop there, because if the mysterious substance is completely immune to any forces, a particle of such substance wouldn't have any force on other particles of the same substance, so it'd just become a floating mass of random moving particles that permeate everything on their way. ☢ Ҡieff⌇ ↯ 23:30, 6 November 2005 (UTC)

I've been trying to start up a personal study of the Relativity Theory and related concepts. My problem is as follows. Consider a situation with two clocks, A and B. From the viewpoint of clock A, clock B is moving at a constant speed. If I understand special relativity correctly, time moves faster for clock B, because it is moving. When clock B returns from it's journey, clock A wil be a little bit behind clock B. So far so good, but if we choose clock B as a reference frame, instead, it's clock A that's moving, so clock A should be moving faster, and clock B should be behind when they are re-united.
I feel I have some fundamental misunderstanding of the theory, and I was hoping someone might clear this up for me (or at least point me to some page that explains this).
While I'm at it, I was also wondering if somebody could recommend a good book explaining both special and general relativity, at a thorough level. I'm quite willing to make an effort and study the complex geometry involved in general relativity, but right now, I don't really know where to start.

Well, you have K drawn numbers and N-K non-drawn, then there are

The force of gravity pulls the Earth upward, toward to people in the air, by an amount equal to the downward forces. Otherwsie, if any force is exerted on the Earth in just one direction, such as when an atom in space hits the Earth at high speed, the Earth will move, just by an extremely small amount, due to the difference in mass.

The moon and the sun rotate, but asteroids and comets don't? What is this special force that causes the rotation?If we can identify it, can we explain why Uranus rotates in the opposite direction to the other planets? Can we define a mass limit for planet rotation?

The solar wind must push the planets out a bit further than their natural orbits (based on their orbital velocities). I would expect this effect to increase proportionally with the cross-sectional area of the planet, and decrease proportionally with the planet's mass, and decrease in proportion to the square of the planet's distance from the Sun. Now, a planet with a highly elliptical orbit would be expected to be pushed out more when closer to the Sun and less when further from the Sun. My question is, would this tend to make all orbits more circular over billions of years ? If so, I would expect the inner planets to make this adjustment more quickly than the outer planets. The innermost planet, Mercury, might have it's orbit disrupted by solar flares, etc., which could negate this effect.
Looking at the following chart, it does appear that the eccentricity of the planets Venus, Earth, and Mars follow the expected pattern:
- Eccentricity..Planet
- =========.======
- 0.20563069...Mercury
- 0.00677323...Venus
- 0.01671022...Earth

Ok, time for some calcs:
From: http://www.lgarde.com/people/papers/TESS/ (a site on solar sails)...
"The areal density, including payload, will be 3.63 g/m^2, giving a characteristic acceleration of 2.26 mm/sec^2" (0.00226 m/sec^2)
Earth's mass = 5.9736×10^24 kg = 5.9736×10^27 g
Earth's cross sectional area = piR^2 = pi(6,372.795 km)^2 = 127,587,980 km^2 = 1.2758798×10^14 m^2
Earth's areal mass = 5.9736×10^27 g / 1.2758798×10^14 m^2 = 4.882×10^13 g/m^2
Set up a proportion:
[3.62 g/m^2] / [4.882×10^13 g/m^2] = a / [0.00226 m/sec^2]
a = 1.676 ×10^(-16) m/s^2 (accel of the Earth if only solar wind was acting upon it)
v = 6.033 ×10^(-13) m/s hour (speed after 1 hour)
v = 1.448 ×10^(-11) m/s day (speed after 1 day)
v = 5.288 ×10^(-9) m/s year (speed after 1 year)
v = 5.288 m/s (speed after a billion years)
At that speed it would take about 1.8 years for the Earth's orbital radius to double.
So, I conclude that the solar wind is sufficient to have noticeable effects over time, if unbalanced. The Earth would have long ago been blown out of the solar system if this force was unbalanced regarding the mean orbital distance. My theory is that it is balanced, in the case of average orbital radius, but not in the case of eccentricity of the orbit, which should then even out over time. StuRat 23:46, 7 November 2005 (UTC)

I heard a recent discussion on the radio about Comets & Asteroids. One of the contributors intimated that all the water on earth came from comets or asteroids colliding with our planet (and presumably melting). Apparently the elements for water would not or could not combine on earth without a vast input of energy. Any comments would be welcome.
"The component of primordial solids of major importance as a source for terrestrial water is hydroxyl ion. This ion forms a regular structural component in magnesium and iron hydroxysilicates, which form the major mass of carbonaceous chondrites of Type I (Wiik, 1956). (Crystal hydrates of magnesium and sodium sulfates found in carbonaceous chondrites are probably not generated in space where they are unstable; they are likely to be forming by reaction with water vapor in terrestrial museums.)"
"The fact that meteorite materials carry sufficient hydroxyl to account for the entire hydrosphere on Earth should not be taken to mean that the Earth formed from any of these specific materials, which probably represent different condensation events and regions in space. But the observations [487] imply that primordial condensates in different parts of the solar system, although varying markedly in chemical composition (ch. 20), have incorporated substantial amounts of volatiles, which were subsequently released in the accretional hot-spot front during the formation of the planets (sec. 26.3.2)."

This question goes back to burning in cigarettes, what does the alternative cigarettes use to make their smokes burn since they don't use tobacco leaves?

No, they have some that are filled with things like a blend of smoking herbs: Marshmallow, Yerba Santa, Damiana, Passion Flower, Jasmine and Ginseng. If there is no tobacco or nicotine what chemical aids these herbs in burning?
All these things can burn but not well, I agree. But is there specific chemicals added to these herbs or leaves that aid in their burning to make the burn slower and better?
Most dried leaves (including tobacco) burn pretty badly on their own. Commercial cigarettes tend to be doped with saltpeter and glycerin to make them burn more steadily, and save you having to relight them. The only thing keeping a hand-rolled plain leaf cigarette burning is the paper and an occasional relight. The burn will also depend on how you roll it - how densely packed, how fat the cigarette is. But for commercial herbal cigarettes, I imagine they would be doped with glycerin and saltpeter like commercial tobacco cigarettes. 84.43.1.92 11:01, 14 November 2005 (UTC)
I'm researching the skin effect and referenced the article so titled. Digging through the equations in various articles, I see several examples provided for copper at various frequencies.
Replicating the table should be straight forward. Using articles found under "Resistivity" and "Permeability (electromagetism)" and "angular frequency", I find that the formulas provided do not work with the sample tables provided in the various articles.
My suspicion is that the units between the articles are messed up and not comparable.
For example:
Copper wire at 10kHz is indicated as a skin depth of 0.66 mm.
Using resistivity of copper as 1.7 x 10^-8 (table in resistivity article
Angular velocity of 2pi/(1/10000)= 62831.85 (formula in angular velocity article)
Permeability of copper as 1.256629 (table in permeability article)
The result is 8.24-7 and no definition of units is described.
The table in Skin Effect indicates 0.66mm
What gives?
Why did you use angular velocity? Skin effect from tables is an exponential effect, current tends to travel and vary exponentially as you go into a conductor. Dominick (ŤαĿĶ) 21:33, 8 November 2005 (UTC)
Good question. The Skin Effect article describes the depth as d=sqrt(2p/wu) where w is angualr frequency of current=2pi x freq.
What is the frame of reference that makes a moon crescent appear to be on its side? Any why is that this position appears to change over the course of an evening? --John
My question is specifically in regards to the moon cresent: sometime it appears in a "vertical" position, at other times it appears in a more "horizontal" position.
No, no, no. This is simple: the lit side of the moon is lit by sunlight, so the lit side is always oriented directly toward the sun. With a crescent moon, this means that the inside of the crescent is oriented directly away from the sun. Draw a line from the center of the dark edge through the center of the lit edge and onward, and it points to the sun.
You can verify this by eye if you look at the moon in the daytime; of course, you must be careful not to hurt your eyes by staring at the sun. Similarly at night, the lit side of the moon points to wherever the sun is below the horizon, on its path (as seen from the earth's surface) from the sunset point back to the sunrise point. Note incidentally that this means that the unlit side of the moon is always the upward side, at night: if you see it any other way in a movie, you know they faked it and got it wrong. --Anonymous, 01:20 UTC, November 9, 2005

The developmental stages of organisms sometimes reflect aspects of the biological history of the species. The organism's earlier evolutionary forms would have been superseded by its later, modified physiology; thus, its earlier forms would have passed into redundancy, expressed only as 'shadows' of previously existing physiology. Taking the butterfly as an example, during the time that it was evolving wings, it would have 'left behind' its previous wingless form - it would not have lived part of its life as a wingless orgasm, then after metamorphosis changed into a partly winged creature (its evolving into a fully winged creature not having been completed yet). The butterfly's present developmental stages seem to show the expression of both the current final stage of evolutionary development as well as the earlier segmented caterpillar form being carried along in tandem as a fully functioning organism (albeit as a defined developmental stage). Why didn't the earlier physiological form of the organism, i.e. the caterpillar, get sloughed off and consigned to its evolutionary history?
Dudley Warrington
Thanks for the insights and contributions . I suppose I'm essentially asking what evolutionary mechanism leads to the development of the metamorphosis stage, without the organism evolving out of its earlier form (as expressed by the caterpillar). DW.

My brother is on a low salt diet due to high blood pressure. He recently had surgery which required that he get his fluids via saline solution. However, the sodium content in the saline caused his BP to spike dangerously. When he complained to the nurses, they said they only had one concentration of saline solution for patients. Is this true in general, or do lower concentrations exist for patients on reduced sodium diets ? StuRat 17:32, 9 November 2005 (UTC)
No, no, no. None of that info about saline concentration is relevant to your brother's blood pressure. BP does not respond acutely to saline and there are a number of risks from giving a hospitalized patient a hypotonic saline solution. The far more likely causes of acute high bp include pain, immobility, stress, discontinuation of home meds, accurate detection of higher bp than expected, and some other things. This is not the place to second guess your brother's treatment. alteripse 22:17, 9 November 2005 (UTC)
IV normal saline solution contains sodium at the same concentration as exists the blood. The cells in your body expect a certain ambient sodium concentration, and get upset if you muck with that. (Too low results in hyponatremia). To simplify, IV fluid with low sodium concentration will be driven by osmosis into the body's cells; it won't stay in circulation where it presumably is wanted. The salt in normal saline won't cause a spike in blood pressure when administered, because it's at the same concentration as what's already in the blood.
There are other things that may have caused the spike in blood pressure. Your brother can and should speak to his surgeon or his physician about them. (To pull one random example off the top of my head, I might ask if he received any sort of locally injected anaesthetic immediately before his BP went up. Lidocaine, for instance, contains a small amount of epinephrine to increase its effectiveness. However, if by random chance and bad luck the local injection hits a vein rather than just soft tissue, the spike of ephinephrine in the blood will cause increased heart rate, sweating, nervousness—the whole fight-or-flight response.) TenOfAllTrades( talk) 12:36, 10 November 2005 (UTC)
I don't believe he was expecting the worst, at least not from the saline solution. Admitedly, the surgery itself may have made him nervous, though. Here's a good source: [28]. This particular passage relates to my brother's case:
"....a large subset of patients with essential hypertension responds to salt loading and restriction with pronounced changes in blood pressure, which has led to the concept of salt sensitivity." StuRat 20:28, 10 November 2005 (UTC)
StuRat, I forgot you were the questioner and it was your brother. I still think an iv fluid error an extremely improbable explanation. In the US 3% saline usually comes in different sized bags, with red or bold labeling and often is not stored on the same ward supply shelves. It is very rarely used and would be an unlikely error, especilally since there are so many more common causes of sudden high BP in a hospitalized adult. alteripse 22:03, 10 November 2005 (UTC)
Good day.
I'm beginning work on a project - BPM - and I'm working with folks in IT. I've been doing a little research around Configuration Management and Change Management. I've run across these terms in an article discussing the benefits of Config. Management and the author mentioned these two terms in context of what might be tracked and managed.
I've not been able to find a reference that defines the diference between these two states.
Can you point me in the right direction?
Thanks.
Change management is for an existing system for which changes must be tracked. Configuration management and Software configuration management ( SCM) are the more general case for both new and existing systems. In other words, a production configuration is for an existing configuration, because no one in his right mind would go to production without a pilot plant. A Stored configuration is something which existed in the past, with possibly a list of the capabilities that it offered. Someone experienced would also be able to list the deficiencies in both the Stored and Existing configurations. The changes are tested against Regression tests and the successes/failures are tracked in one of these systems as well. In other words you need multiple configurations to get anything done nowadays.

He is one of the originators of this field.

The best explanation for the second question is that laying a large number of eggs is an r-selection reproductive strategy. Many species produce an enormous excess of gametes or offspring because only a few will survive. This is true for most insect species, and for most species that deposit gametes or young in a risky environment. In this reproductive strategy the parent invests almost nothing in the way of effort or food in the rearing, and most perish. The opposite is called K-selection, where only a small number of offspring are produced but the parents continue to invest large effort or food resources into rearing the offspring and a high proportion survive. alteripse 11:37, 10 November 2005 (UTC)

I saw this egg-inverting trick in a Japanese sushi manga:
The hero was in his restaurant when the old guy came. He said: "I'll sell you a chicken that lays inverted eggs." Our hero did not buy his words. So the old guy boiled an egg and opened it. Our hero was amazed to find the egg really has yolk on the outside and the white inside. He paid 100,000 Japanese Yen and accepted the chicken only to find out a week later, that chicken was a cock.
The old guy came to the other chef. This time he taught that chef the trick for 200,000 Yen so he can challenge our hero.
Our hero was totally hopeless. He went to his sushi teacher, only to find out his master tried to make it according to an antique cookbook while he was young. The book taught him to preserve the eggs in miso and rice bran. No, it didn't work.
At the day of the match, the bad chef made a sushi with an inverted chicken egg. People were amazed. However, our hero made a sushi with inverted multiple quail eggs. The bad chef said to himself, "It's hard for me to do it with a large chicken egg. How could he make it with quail eggs?"
(You may want to use a large egg.)
(You may want to use a very small egg so the yolk adheres to the shell more evenly.)
Well, I plan to try it at home. I guess it is a magician's trick. But I know I am too clumsy. I can never be a good chef. The manga author said the egg white tend to adhere to the metal. I don't buy his theory. The only alternative explaination I can think of is the centrifugal force. So I guess I could do it with spinning. -- Toytoy 16:32, 10 November 2005 (UTC)
Hello, Digital radio is getting a lot of press & is very popular, despite the fact that the sound quality isn't as good as is purported, however I have always suspected that the fact that it is digital rather than analogue means that it is easier for it to be blocked or jammed by national governments. Is this the case. If all radio had been digital in WWII would radio free France & radio free Poland, etc have been able to get through? or would they have been easily blocked (more easily than the Nazis were able to block the analogue radio transmissions)?

Because I hate the movie, I decide to take my brand-new spaceship and fly away at c (hypothetically) to deep space in the opposing direction of the light coming from the screen to the Earth. The question is: When I'm still accelerating, say at 0,5c, I should see the movie slowing down (in my reference frame) and in the hypothetical arrival to c, the movie should stop due to time dilation. Can anyone explain me what do the photons do exactly here? Is it something like the photon from the screen chases me but not fast enough to catch me in finite time? Wouldn't this be in contradiction with the universal constancy of c?

It's probably just me being paranoid, but I'd rather put my mind to rest. A few weeks ago my class in Biology did a experiment where we extracted DNA from onion cells into test tubes, and then stained the DNA so that it would show up in the test tube. I'm not sure if we were supposed to add the stain ourselves or if the teacher was supposed to do it, but either way I added the DNA stain myself and got a little on my fingers. And at the time I thought it might be a tad dangerous - anything that stains an onion's DNA could affect mine (possibly?) - and it stained my fingers, but I washed most of it off and it disappeared soon enough, so I didn't think about it. But just now I've heard from a friend who did a different experiment, also using a DNA stain, and they were told not to get any on their skin or it could mess up their DNA. Which led me to worry. It probably doesn't help that I don't know which particular stains I used or they used, but I seem to recall it being blue. So am I in mortal danger, or is it nothing? I mean, the school wouldn't let us use something extremely dangerous, would they? -- Sum0 22:37, 10 November 2005 (UTC)

Dear sir, I am trying to find out which is the biggest sea in the world.

It's the Coral Sea near the Australia. It is 4.800.000 sq.km
That depends on how you define the sea and what constitutes a sea (as opposed to an ovean) in the first place. The Mediterranean Sea is well defined because the Strait of Gibraltar is so narrow, but where would you put the border between the Coral Sea and the Tasman Sea? (And why are they separate seas in the first place?) That's pretty arbitrary and I suppose that's the reason figures on the size of a sea may differ. DirkvdM 11:58, 11 November 2005 (UTC)

I'm just wondering if there's a way to do something in Acrobat. Let's say I have a PDF with, say, six pages: ABCDEF. Is there a practical way to turn it into AABBCCDDEEFF? By "practical", I mean, "other than doing it one page at a time". I'm interested in doing this to a document with about 150 pages, so the ability to scale it up is important. I couldn't figure out an obvious way to do this but it doesn't mean that it can't be done, of course. (The reason, by the way, is that the pages are scanned in as two to a page, horizontally. This is fine for printing, but for reading on the computer it is difficult. My theory was that if I could duplicate each page, I could then crop the even-only pages and odd-only pages so that they were left and right pages respectively, and make it so that each PDF page corresponded to only one page of the document, rather than two. If there's another way to accomplish this, I'm all ears.) -- Fastfission 19:19, 11 November 2005 (UTC)

I am learning about the blood coagulation cascade. While I understand that Thrombin catalyses more than one reaction, I believe that the most important of these is catalyzing fibrinogen to fibrin, so that stable clots can be formed. What I don't understand is, if the thrombin is available for previous reactions in the coagulation cascade, such as the conformation of factor VIII to factor VIIIa, then why isn't it possible to skip the all the previous steps of the cascade, moving directly to the formation of fibrin? Why are the previous steps necessary?

Do they have to be your own? And is this meant as a serious question? Ah, well, even it is not, it's an interresting bit of trivia. I'll take 'judge' to mean 'measure'. An anemometer would need some time to get up to speed and farts probably don't last long enough for that. Also, a fart is a narrow jet of air, and I don't think anemometers would be able to handle that (unless they're very small perhaps, which might also deal with the first problem). However, pressure anemometers probably don't have the first problem and a tube anemometer might not have the second problem either. But the thought of inserting a tube in my arse makes my cheeks somewhat anemic (now that's a rather lousy word joke even by my standards - and don't make jokes about which cheeks I mean, please).

A suggestion on QI last night, that I've once wondered about too. Considering that outer space is about 100 km up, wouldn't it be possible to build a ladder or lift that high, so we wouldn't need those expensive rockets? (A modern day tower of Babel.) Of course this would also cost a bit, but you'd only need to build it once. And working the lift would also cost energy, but I assume it would be much more efficient than a rocket, which probably spills most of its energy sideways. And the engine and fuel could remain on the ground in stead of having to be transported as well (I suppose this is the biggest advantage). Once there, a rocket would need only a fraction of the energy to get further out in space. If you go high enough, centrifugal forces of the rotating Earth might even be used, to the point that it actually generates power in stead of consuming it. This is getting to sound better and better as I write it. DirkvdM 15:40, 12 November 2005 (UTC)

-- 59.93.129.191 02:33, 13 November 2005 (UTC)
He doesn't quite say so, but I suspect he's talking about the simplest kind of electrical tester, which has two leads and a neon lamp inside, along with a big old (100k or so) series current-limiting resistor, since small neon lamps require a ridiculously small amount of current. Secondly, I suspect he's asking about the case where you connect one lead of the neon tester to a hot wire, and hold the other lead in your hand. In this case, the neon bulb will in fact glow -- not as brightly as when you connect that second lead to the neutral or ground wire, but still plenty bright enough for you to see. (And in fact this effect leads to a useful trick, one I use all the time: determining which of two indistinguishable wires is hot and which is neutral.) The current flow -- if indeed there is any -- is so tiny that you don't feel a thing.
The explanation for why/how this works always involves phrases like "the capacitance of your body", although this has never made perfect sense to me. Steve Summit ( talk) 19:50, 20 November 2005 (UTC)

High CPU usage indicates your computer is carrying out a processor intensive task (of which there are many). Some of these required large amounts of RAM, and some do not.

For the medicine answer, you could even ask a doctor. Over 99% of the math used in clinical medicine by doctors and nurses is straightforward arithmetic and simple algebra: especially percentages, ratios, unit conversions.

Say you had a drop of blood and wanted to know whether it came from a man or a woman. How difficult would it be? Would the easiest way be to look for the X or Y chromosomes in the blood cells? Can you even tell X and Y chromosomes apart with an optical microscope? — Keenan Pepper 04:37, 14 November 2005 (UTC)
Well for starters, red blood cells have no nuclei and no chromosomes, so there wouldn't be much in the way of visual clues to sex unless you could pull down their little pants. White blood cells can be stained to show nuclei with Barr bodies under the microscope. A Barr body is a partially inactivated second X chromosome and, though not infallible, is generally a better clue to female gender than a pink hair ribbon. Staining for Barr bodies is old technology however, and if you want something slightly newer and less fallible, you can rely on the good old peripheral blood karyotpe. Perhaps the most up-to-the minute test for sexing blood is detection of the SRY antigen, a pretty reliable indication that the owner also sports a set of testicles. So take your pick. alteripse 05:26, 14 November 2005 (UTC)

The above section named "Some Fundamental Results" in the page "Mathematical Logic" has been changed by the user Otto ter Haar on the 9th of October. The old text read: "Given a first-order formula as its input, the procedure eventually halts if the formula is valid, and runs forever otherwise." The new text reads: "Given a first-order formula as its input, the procedure eventually halts if the formula is valid or not valid, and runs forever otherwise." I do not know or could not find out, what motivated ter Haar to enter this change but it would be an incredible (and unbelievable) result, contradicting all our knowledge of computational theory and computability. The only reason - which I could imagine - to justify this statement, i.e. that there is a theorem prover, which works for valid as well as invalid formulas, is to assume certain finite domains, and do model checking. Nevertheless, this should be somehow included in the modification of this article. Otherwise, it leads to a contradiction with the statement that first-order logic is recursively enumerable (which means all valid formulas can be constructed) and that it is NOT recursive (which means that there is no decision procedure for saying whether a formula is valid or not) - and these two statements are enormously important results for computational theory and are general textbook knowledge. It is also unclear, in what situation the procedure would not terminate - since the modified statement implies that the procedure (the theorem prover) always halts (since in standard logic, there is only true or false). It would be appreciated to get some feedback, especially by ter Haar, on this change and my concerns about it.

Don't forget the other, albeit slower mechanism the eye uses to adapt to darkness-- the synthesis of
rhodopsin in the
rod cells of the
retina. Light exposure depletes rhodopsin from these photoreceptor cells, while darkness permits a metabolic re-stocking of this substance. Actually, full darkness is not necessary in order to replete rhodopsin stores; the rods are insensitive to red light, which permits darkness adaptation with the use of
red adaptation goggles. Using these devices, the eye can continue to function using solely the color-descriminating
cone cells' ability to respond to red light, while the rods adapt to darkness.--

Can anyone help me to get the answer for the question"Can Menstruation will be happend without releasing egg? "
But this is the problem with theoretical answers because the answer is certainly yes. Menstrual bleeding without ovulation is called anovulatory bleeding. It is the most common type of infertility. It characterizes the menses of the first year after menarche in most girls. It characterizes many of the menses as menopause approaches. Women with polycystic ovary syndrome and several other types of hormone imbalances typically have menses despite chronic anovulation. Anovulatory menses are characterized by irregularity, unpredictability, variation of length and heaviness from period to period, lack of mittelschmerz, and lack of premenstrual physical symptoms. Finally, any woman taking birth control pills typically has menses without ovulation. alteripse 11:23, 15 November 2005 (UTC)

RECOGNIZING A STROKE
Thank God for the sense to remember the "3" steps. Read and Learn! Sometimes symptoms of a stroke are difficult to identify.
Unfortunately, the lack of awareness spells disaster. The stroke victim may suffer brain damage when people nearby fail to recognize the symptoms of stroke.
Now doctors say a bystander can recognize a stroke by asking three simple questions:
1. Ask the individual to SMILE. 2. Ask him or her to RAISE BOTH ARMS. 3. Ask the person to SPEAK A SIMPLE SENTENCE (Coherently) (i.e... It is sunny out today)
If he or she has trouble with any of these tasks, call 0-0-0 Immediately and describe the symptoms to the dispatcher.
After discovering that a group of non-medical volunteers could Identify facial weakness, arm weakness and speech problems, researchers urged the general public to learn the three questions.
They presented their conclusions at the American Stroke Association's Annual meeting last February. Widespread use of this test could result in Prompt diagnosis and treatment of the stroke and prevent brain damage.
A cardiologist says if everyone who gets this e-mail sends it to 10 people;you can bet that at least one life will be saved.

Is this correct? - Ta bu shi da yu 01:14, 16 November 2005 (UTC)
It seems like a reasonably reliable screening method for a stroke, but I have trouble imagining a lot of lives saved. For this to actually save a lot of lives, the following facts would need to be true: (1) a large portion of strokes are misinterpreted as something else that does not seem to require urgent care, (2) a large portion of strokes go without early treatment that would lead to a fulller recovery than commonly occurs at present, (3) this screen would lead to an increased proportion of stroke victims getting early care that would produce a better outcome than getting later care. This is not my area of expertise but I suspect all three propositions are somewhat debatable. alteripse 01:24, 16 November 2005 (UTC)
If you know the derivative of a function, then you know the function up to a constant. If you know the gradient of a scalar field, then you know the field up to a constant. But even if you know both the divergence and the curl of a vector field, that's not enough information to determine the vector field up to a constant. For example, <x,-y,0> has zero divergence and zero curl but it's not a constant. Is there a third property of a vector field that, together with divergence and curl, provides enough information? — Keenan Pepper 01:28, 16 November 2005 (UTC)

The best explanation I heard for the disappearance of so many ships in this area is that the continental shelf off the coast of America contains a lot of methane gas which is frozen due to the pressure in the deep ocean. The shelf is not hugely steep and if there is an underwater land slide this methane is released as a kind of big Jacuzzi, like swamp gas. (ever stuck a stick in the bottom of a muddy pond and seen bubbles rise up?) Ships cannot float on water full of bubbles and they sink. Others catch fire and sink if the gas is ignited by the ships boilers/electrics. It’s all very local and all very quick. This might explain some of the strange disappearances but not all and I might add that this is just what I read somewhere as a possible explanation for some of the disappearances.-- Eye 23:13, 16 November 2005 (UTC)

Draw two big circles that overlap a bit. (The images at Venn diagram should illustrate this.) Label one circle with the name of one kind of candy (suppose it's "candy A"), and the other circle with the other kind of candy ("candy B").
Write things that are similar between candy A and candy B in the middle section (the intersection of the two circles). Differences should go in the rest of the circle. For example, if candy A is square and candy B is round, you would write "square" in the "candy A" circle, and "round" in the "candy B" circle.

What exactly is a Sugar High if there is such a thing. What is the biology behind it. Doing this for my bio coarse.
A Sugar High is a concept of American folk biology. The concept is that excessive sugar will somehow make someone either "intoxicated" (e.g.,
Twinkie defense) to the point of diminished judgement or responsibility, or in its milder forms, euphoric. Either response of course, puts sugar in the cultural Bad Food category. The first concept is nonsense and the second perhaps has a nidus of scientific fact in the middle of the cultural concretion.
In terms of verifiable science, there are perhaps two relevant phenomena. First, sucrose tastes good, and this taste sensation is strong enough that studies have shown it can be used as an analgesic in infants-- this is part of the basis of the euphoria concept. Second, it is possible to show in animals that high or low dietary carbohydrate intakes produce somewhat differing effects on level of arousal of the autonomic nervous system. Unfortunately for the Sugar High meme, however, the effect of carbohydrates is generally sedating rather than arousing. alteripse 12:21, 17 November 2005 (UTC)

I am trying to relocate a piece of information that I recall reading years ago. It was an article / study that tracked how our eyes commonly move when we are confronted with new information - such as a new package, a new magazine cover, a billboard, a print ad, etc. I seem to remember that the researchers discovered that our eyes commonly move in what I would call a flipped number 6. (Sorry, i am bad a trying to describe spatial stuff - so bear with me) the pattern described was as if the eye were writing a backward "6" - starting at the upper left of the picture, and scanning right and down, and looping back up and to the left - ending at about the center of the item. Can anyone help me validate this? I have tried the following searches - and again - I am a first time user, so I may not be searching effectively: tracking eye movement / how does the eye move when confronted with new information / how does the eye scan a page / etc - and I have had no success so far.
Thank you very much in advance for helping me with this.

The term you're looking for is Eye tracking, here are some related links that I'll add to the article:
- Eyetrack III study
- eyetools study
- ViewPoint EyeTracker software
- Applied Science Laboratories trackers
The first document features something that vaguely looks like an inverted "6". However, it's important to note that the path that the eye takes varies quite a bit depending on what it's looking at. For example, my eyes automatically seek the upper, left-hand corner of an English document; but when confronted with Hebrew, they go to the upper right without any conscious thought on my part. When looking at artwork, my eyes tend to seek out areas of the highest contrast first and then follow contours. These trackers are very useful for determining what people notice in an advertisement, which things are distracting, and which elements are overlooked. Lastly, you did a great job asking the question. Cheers! -- Avijja 07:57, 18 November 2005 (UTC)

Our article on Familial Alzheimer disease should anwser your question. The condition is inhereted in an autosomal dominant pattern, which means that only one parent needs to have an inhereted or spontaneously mutated gene associated with FAD for the condition to be passed on, thus with about ~50% chance of the offspring getting a mutant copy of the gene, the disease then has a pretty good chance of becoming fixed in the population. I haven't come across the term "private mutation" before, but often papers focus on a particular family and this term might be being applied to the specific muation in one of the FAD associated genes common in that family.-- nixie 03:39, 18 November 2005 (UTC)

What is the theory of Matter? Can u summarize it for me please?
The basic idea is that ordinary matter is composed of isotopes of the elements in the periodic table and ions of those atoms. Note that this excludes matter in nuetron stars, black holes, and some other special cases. These atoms are in turn made of protons, nuetrons, and electrons, which are in turn composed of quarks, which are in turn made of strings, etc. StuRat 15:17, 19 November 2005 (UTC)

1. Is light a continuous stream of photons? If so, light traveling from a distant star must connect the observer with the past in a very real way. In other words, along that continuous stream of photons some photons actually belong to part of the stream that is thousands of years older than other parts of the stream. How can such a structure exist? This stream of photons not only crosses vast distances of space, but also of time -- yet it remains a single unified structure that can carry a continous stream of information. Gary O-- 65.66.151.189 04:06, 18 November 2005 (UTC)
Going back to the original question: think about a snapshot photograph of a stream of water coming from a water hose and that the stream is an entity of water molecules being emitted from that hose. The water molecules at the end of the stream furthest from the hose are older than the water molecules that have just come out of the hose. Now go to live action: watch as the hose is modulated (wiggled around) and watch that information travel in time to the end of the stream. I think that's the concept you are trying to capture. As always, analogies eventually fail so don't take this water stuff too far. :-) -- hydnjo talk 02:21, 19 November 2005 (UTC)
If light waves contain quantized particles that we call photons, why don't sound waves contain quantized particles as well? Why is it that light is special and not other types of waves?

I am trying to remember the name of a phenomenon. While touring a nuclear reactor, I remember looking into one of the cooling pools and seeing the core (or rather what one can see of the core, as it is not the core itself, obviously). There was a blue light emanating from it and I asked my dad about it. My recollection of what precisely is fuzzy (hence my desire to remember the name), but it seemed that the light was a result of super-excited particles tearing out faster than the speed of light (in water) and reacting with the water, creating the eery blue light. I recall stumbling upon the name and I believe it was Something Effect (imagine that), something being the actual name. I believe it started with an M, but I'm not certain. If someone knows the name that would be of great help, then I could read about it again.

Okay, it's getting to be the time of year for cold weather, fleece jackets and static electricity. So here's a question that's baffled me for a while.
Suppose my jacket has acquired a lot of static charge. If I am holding or wearing the jacket and I touch something metal and grounded, I get a bit of a shock. But if I take the jacket off and touch something metal and grounded through it - so here the fleece and the metal are in contact, and my finger is not between them - I get a much larger shock.
The explanation I had thought of was that the more direct contact between the fleece and the metal meant there was less resistance for the static discharge, resulting in a stronger spark, and my finger would still be next to the spark and feel it.
But here's the weird thing. Suppose I take the jacket off and put it over the back of a chair with a metal frame, without touching the frame. There's no static discharge. But if I then touch the frame through the jacket, then I get a big static shock (and the fleece becomes much less staticky). Why does that happen? Why won't it discharge until my finger is there?

Dear sir, i have the problem regarding the swelling around both ear at the lateral part of the ear i meet to some doctor to reduce that swelling ,but it goes invain due to such swellin on the face face seem to very eagly,
some doctor told it is the excessive growth of the saliva gland ,i dont know what is the actual reason behind the but it is not due to the obesity,the inflamation like the growth of laterl part of chick under ear and around the ear and on the jaw ,please sugget the remady on this thanks
It would be helpful to know precisely where the swelling is. For example, swelling of the external ear, or pinna, presents a completely different problem than swelling of the parotid gland or the angles of the mandible.
Assuming your doctor is correct in that the swelling is located in the parotid gland, the problem could be any of a number of things: viral parotitis ( mumps), autoimmune disease such as Sjögren's syndrome or Miculicz syndrome. An important criterion for diagnosis would include the time line of symptoms-- i.e., how suddenly the swelling appeared, and how long was its duration.
In any case, you might want to prevail on your doctor to provide more information, or to refer you to a facility or another doctor that can. Some of these conditions are not trivial, and their significance to health goes beyond simply being a cosmetic liability. --

How does one calculate the pH of a solution when a weak acid is added to a weak base? How does the method differ to weak base and strong acid etc. Is it acid specific?
Such a question is off the specification for my Chemistry course, the teacher didn't know so I'm interested!
---DK
The general solution for the case of a weak acid/weak base leads to a cubic equation for the hydrogen ion concentration, which is obviously not simple to resolve. In general, weak acid/weak base titrations are impossible to perform with a coloured indicator or a pH meter, although they are sometimes possible by conductimetry. This is probably why they are not on your course specification. Physchim62 (talk) 07:05, 22 November 2005 (UTC)

It rings of a bell, but I can't remember at the moment; what it probably does is try to make "holes" in the walls between the matrix and intermembrane space of the mitochrondria, that way, energy production from glucose is less efficient, ie. instead of 36-38 ATP per glucose molecule, it is 20+ or even less or something. Hence, you burn more food/glucose (and fat which is converted to glucose) for the same amount of activity. This is dangerous of course, because if it ends up being that it takes more energy to metabolize food than it produces, then you have an energy loss just by thinking or breathing, rather than merely slowing down energy production. I've come across the article before. This should lead someone else in the right direction. -- Natalinasmpf 21:16, 20 November 2005 (UTC)

Does anybody have any good references for the "computational model" underlying entertainment DVDs? There's quite a bit of variation in the way the scene selection and other menus work, and in the kind of effects that can accompany the special features. It seems that each DVD's menu tree must, in effect, be written in some kind of programmng language, but obviously one that is ultimately represented in some nicely device-independent form, since the DVD's can not only be played on general-purpose computers (both PC's and Macs) but also of course on dedicated, single-purpose DVD players. I'm curious to know what the specification of that "programming language" is, and what features it supports.

Hi. I read a while ago that an array of photovoltaic solar panels 100 miles square in the Nevada desert or Arizona would generate enough electricity to meet all USA power needs. My question is how much would this cost (& how does this compare to the total cost of a nuclear power plant - including decomissioning cost & storage of radioactive material, etc). I'd assume that the solar array would need to be raised off the ground (say enough to allow a car to drive under it) for maintenance & that the solar panels should tilt (both to catch the sun better & to knock off any dust/sand that blew onto them) so some engineering cost would be needed as well as the costs of the panels.

I don't think it has a specific name, as a shape, but the set might be named after whichever mathematician first thought it interesting enough to publish on.

Don't think theres any special name. Removing the rationals from the real number line turns it into a "fat" cantor set. (the "fat" mapping is accomplished via the Minkowski question mark which maps rationals to dyadics; the construction of the cantor set is via dyadics (i.e. middle-third removal)). linas 00:08, 24 November 2005 (UTC)
Can the elements in a solution be seperated back out into their original form? Does a solution act as a mixture or as a compound, or can a solution act as both depending on the elements in solution?

The M3 Lee is a World War II tank with a 51 mm front armor made of ordinary steel. If a modern M1A2 tank fires a round of 120 mm armour-piercing fin-stabilized discarding sabot ( APFSDS) at it at close range, would the depleted uranium kinetic energy penetrator fly straight through it from head to tail?
Since the M3's steel armor is not too slanted, the effective thickness of armor cannot be too thick. I think many modern penetrator can easily 500 mm.
Then how about a 75 mm thick M4 Sherman or an 180 mm thick Patton tank if you only have steel plates?
Can several modern tanks sink a heavily armored WW2 main battleship if the ship stays within their effective firing range? I mean you can aim at a point slightly below its water line. And if a tank cannot destroy all watertight compartments, several tanks may carry the required amount of ammunition. -- Toytoy 16:56, 21 November 2005 (UTC)

It is debated whether T. rex was warm or cold blooded, and no definitive evidence exists to disprove either argument.

What is the storage location and adress (computer related)
The location in memory where a byte of information is stored is described by a number (the address of that memory location). For example, if your name was stored in the computer, it could be written at the very beginning of memory, which would be bit 1 (or bit 0, if they start counting at 0 instead of 1, as they often do in computers). Depending on the length of your name, the next available address in memory might be, say, 30 bytes later. Note that they tend to use hexadecimal numbering, with leading zeroes, to describe memory addresses, as shown below. Thus the next address in memory might be 000000001E:
Decimal Hexadecimal ======= =========== 0 0000000000 1 0000000001 2 0000000002 3 0000000003 4 0000000004 5 0000000005 6 0000000006 7 0000000007 8 0000000008 9 0000000009 10 000000000A 11 000000000B 12 000000000C 13 000000000D 14 000000000E 15 000000000F 16 0000000010 17 0000000011 18 0000000012 19 0000000013 20 0000000014 21 0000000015 22 0000000016 23 0000000017 24 0000000018 25 0000000019 26 000000001A 27 000000001B 28 000000001C 29 000000001D 30 000000001E
Another form of memory address is memory offsets (relative addresses) where the amount to add to a fixed reference address is given, rather than the absolute address. Virtual memory takes this further, and uses a program that figures out where to actually store the data, regardless of the memory address you specify. It uses a look-up table to match the addresses you specify with the real addresses. In most modern programming languages you can, but don't need to, specify memory addresses. Whenever you declare and assign a variable, like X=5, the system figures out a place to store that automatically. The most common place a user will see an address is in an error message, something like "Memory overflow at address...". StuRat 19:35, 22 November 2005 (UTC)
I'm trying to back up my digital photos on CD-Rs. The .jpg files average about 1.4 MB in size. The capacity of the CD-Rs is 700 MB, thus I figure I should be able to fit 500 photos on a disk. However, I'm finding that I can only get about 400 before I run into "disk full" error messages. Furthermore, after I copy only a few files to the CD I sometimes get the "disk full" message. If I take the CD out and place it back in the drive, this message goes away. What's going on? (I use Windows XP)

How does sodium carbonate remove stains from laundry?
For example, an oil stained piece of clothing is soaked in a solution of sodium carbonate and water. Thanks--Curious Person
Why Did Sodium Carbonate (Washing Soda) Dissolve an Oil Stain Thank you for your prompt answer concerning Sodium Carbonate as a stain remover ( "Arm and Hammer's Washing Soda" was used to remove an oil stain without detergent, just soaked in hot water and Arm and Hammer).
The answer mentioned that ..."It softens water by binding to dissolved calcium and magnesium—in hard water detergent molecules tend to bind to those dissolved metals instead of to oil and dirt. Sodium carbonate is also a weak base; in some cases this can increase the solubility of stains in the wash water, removing them from clothing..."
If the water was "soft," and the water did not have to be be softened by binding to as many dissolved calcium and magnesium molecules, would the base of sodium carbonate be able to attack the stain by increasing the solubility of the stain since it was not softening the water as much.
Thanks again. --Curious Person

Hi. I'm doing a project for science and our unit right now is heat. My partner and I have to research about easy bake ovens. First off, we have to discuss the kinetic molecular theory (KMT), temperature, and heat of the easy bake ovens in terms of Q=MC and/or energy for the phase changes. Next, we have to identify where the 3 heat transfers (radiation, conduction, and convection) occur during the process of using the easy bake oven, and then have to apply Newton's law of cooling (Q/T=K (T1-T2)) to it. Lastly, we have to apply the first and second law of thermodynamics to the easy bake oven. All in all, my question is if you could help me gather this information or direct me to some usefull sites of where i could find this information? Please and Thank you.

I am a novice with chemistry, however, I am working on a project whereby I would like to identify a chemical or combination of chemical substances that when combined (mixed) with water will generate a chemical exothermic reaction that will produce extreme heat up to 661 degrees centigrade (melting point of aluminium). Optimally, the process of this reaction would vaporize the reactants, leaving little or no trace elements of the chemicals used and / or the resulting residual chemicals are environmentally friendly (are not pollutants of water or air). And No, I am not building a bomb. The result I hope to achieve is to come up with a relatively inexpensive method of breaking the molecular bonds of a material that could be coated with this chemical substance. After coating the material, the introduction of water would create the desired reaction.

Also can you confirm that I am right in thinking that there is no change in p.d. where two plates are moved further apart while a battery is still connected, and capacitance decreases, so does charge on each plate and therefore energy?

Is water the only liquid that expands when frozen--````````
Arguably no. It is probably only the common one that does, although I think you could come up with another molecule with the intention of having it so. The reason is the fact that in the solid state the water molecules in order to be bonded into a "frozen, vibrating" kind of state, there's a lot of space between the molecules because well, the molecule is like a three-pronged star, and there's a lot of empty space between the molecules despite the fact that the molecules don't move a lot (the "prongs", that is the different component atoms are however due to their charge bonding each other in place)...a bit of a rough and messy description, so bear with me. Other materials don't have quite that structure so that might not happen because when the temperature drops and the molecules don't move as much, less space is wasted. Somebody more skilled should help you here, but I just was wondering if the three-component structure of carbon dioxide has anything to do with it's sublimation properties (ie. dry ice et al)....possibly you could also have a triangular protein... -- Natalinasmpf 23:37, 24 November 2005 (UTC)

Hi
Is there such a thing as the geographic centre of the world? If so where?
If you think 3-dimensionally, the world certainly has a geographical center: it's about 4,000 miles straight down from wherever you may be (assuming you're not reading Wikipedia from outer space). The Earth is a sphere, or more precisely an oblate spheroid, so it has a center. You just won't find it on a map of the Earth's surface.
Perhaps a more interesting idea is the geographical center of all land on the Earth's surface. I think the right way to compute this is to first take the average position in 3-dimensional space of all points of land on the Earth's surface (this will be a point deep inside the Earth, but not at the center), then use the point on the surface directly above this point. I happen to have at hand a suitable data set whose origin I was not told, and have been meaning to program this computation on it for ages... okay, done. If I got it right, the center is 44.50° north, 28.23° east, which is in eastern Romania near Constanta.
Another interpretation is given on this web page: the geographical center of the world's land area is defined there as (in effect) the point that minimizes the average great-circle distance of all land from it. The author of the web page computes this as 37.688° north, 35.438° east, which is in south-central Turkey. The web page states the position to be near Iskenderun, but actually it is closer to Adana.

I just saw that episode of Seinfeld where Jerry and Kramer are watching an operation and a Junior Mint falls and lands inside the incision. Has something like that ever actually happened? What would happen to the patient in that circumstance? Would he get an infection from the non-sterile mint? — Keenan Pepper 01:00, 26 November 2005 (UTC)
Although there have been so many million operations in so many places and circumstances over the last 2 centuries, it is hard to say never, it is extremely unlikely. The trend has been to use smaller and smaller incisions over the last 2 decades, so that few operations involve large areas of open exposure. Overhead observation "bleachers" have not been used for decades in the US. I havent seen the episode but assume from your description that they were observing from an old fashioned elevated observation gallery rather than standing in the OR. No one observng in the OR gets anywhere near the incision because there simply isn't room between the surgeon, a resident, a scrub nurse, and usually more bodies than that. Theoretically the lodging of an unseen piece of candy would result in a foreign body reaction, probably with a local infection and abscess. The problem is that it would be hard to see the problem by x-ray. alteripse 03:08, 26 November 2005 (UTC)

There is much evidence for floods in the distant past (maybe even a few thousand years ago). See Deluge (prehistoric). However, there is no evidence apart from scripture or myths that a single worldwide flood occurred and acted as an evolutionary bottleneck, destroying all humans or animals except those on an ark. There is much evidence that large numbers of people and animals have been in various parts of the world for more than 6000 years. There is also some evidence that some organisms have changed during that time.

I've recently been playing around with a nuclear weapons effects calculator based on the one at the following URL: http://www.stardestroyer.net/Empire/Science/Nuke.html
If I put in yields of say, 15 kt or 1 Mt, it comes out just as one would expect in terms of the order of the width of the effects: 1. fireball is smallest, then 2. air blast/near total fatalities, then 3. ionizing radiation, then 4. air blast/structural damage, then lastly 5. thermal radiation has the widest reach. However for very small blasts, say, 1 kt / 0.001 Mt, the order is different: 1. fireball, 2. airblast/near total fatalities, 3. thermal radiation, 4. air blast/structural, 5. ionizing radiation.

Liquid nitrogen freezes and destroys tissue it contacts. It is no different than burning with cautery, burning with acid, or abrading away. By all methods, it is important to avoid damaging normal tissue surrounding the wart. Unfortunately many skin warts are able to survive and recur. alteripse 13:31, 28 November 2005 (UTC)

How can a person interpret the U.S. Forest Service 'bearing tree' markers to determine the location?
The United States Forest Service places survey markers on trees within the national forests. These are yellow metal plates about 5 inches by 4 inches in size and have numbering on them related to the geographic township and section where the marker is located. The markers appear to have a reference to a section corner with distance and direction, but I haven't quite figured out how to decode the system.
Thank you for your prompt answer concerning Sodium Carbonate as a stain remover ( "Arm and Hammer's Washing Soda" was used to remove an oil stain without detergent, just soaked in hot water and Arm and Hammer).
The answer mentioned that ..."It softens water by binding to dissolved calcium and magnesium—in hard water detergent molecules tend to bind to those dissolved metals instead of to oil and dirt. Sodium carbonate is also a weak base; in some cases this can increase the solubility of stains in the wash water, removing them from clothing..."
If the water was "soft," and the water did not have to be be softened by binding to as many dissolved calcium and magnesium molecules, would the base of sodium carbonate be able to attack the stain by increasing the solubility of the stain since it was not softening the water as much.
Thanks again. --Curious Person

I was reading the article about diabetes and one question came up. I`d know why non-diabetics can not use `artificial` insulin to the day-to-day living.So, doing that they would use less of their own, `natural` insulin and their bodies would not be overcharged by a big amount of glucose that they ingest. So , non-diabetics could prevent the disease . For example , a non-diabetic person that eats to much carbs (glucose) per day is increasing their risk to get the disease , because they overloaded their organism with a big amount of sugar that their body cannot handle 100%. But , if that same person ingest the same amount of sugar and use an `artificial` insulin for that , their body would not have to use their insulin , not overloading the body , and for consequence , not causing diabetes .
Thanks for your answer. -- 69.209.115.22 02:49, 29 November 2005 (UTC) Michigan reader -- 69.209.115.22 02:49, 29 November 2005 (UTC)
Interesting question and not as crazy as it might seem at first look to some. For the purposes of this answer let's restrict it to type 2 and let's use the common simplified story that the following sequence of stages happen as someone slowly develops type 2.
Now the above is perhaps oversimplified and we do not understand all the details of all the steps and there may be other routes to type 2 diabetes.
However, let's get back to your question. We have fairly strong evidence that doing something at stage 3 to reduce hyperglycemia or pancreatic damage may prevent the irreversible death of the beta cells. At stage 3 the person does not technically have diabetes, but can be said to be "prediabetic". This is when exogenous insulin injections might spare the person's beta cells from exhaustion and hyperglycemic damage. So what would be down side to your idea?
So the answer to your question is: I can imagine a situation where that might be a prudent thing to do. Is that what you had in mind? alteripse 03:26, 29 November 2005 (UTC)

Hi, I own a MSN(nee WEB)TV. It has a browser and email and it is fine for home, but, I have little knowledge of deep computer running details. At work, late at night, I have used the company computer to go to Google and Yahoo and on occasion gone to -Adult- sites. I know how to "clear Google history". I know how to use "tools" to delete "recent history". But.. tonight I discovered "internet options" in "control panel" in "my computer" on the desktop and saw a _lot_ of 'incriminating' temporary internet files. Some were very easy to identify and others were either Spyware I attracted (edge.ru4.com, ad.doubleclick.net, etc) or anti-adware that I should leave alone.
I went to Google with some terms and addresses which sent me to computer (self named) Geek forums which listed the few I have cited here. A few were a bit hard to follow as there were lists of "antispyware programs" that looked a tad like the FORTRAN they tried to teach me in 1969. 8-)
Finally, the point and question: is "Akamai.net" one of the 'good guys'? How about "a.as-usfalkag.net"? I was able to help myself by hi-lighting something and clicking on "properties" and anything with a "last [adjusted] date" that was a year or more old was something to keep and anything with today's date and no other info was 'bad'. Some of the 'bad' had today's or tomorrow's date to 'expire' and some had 'none' as a date.
Is my only opton to go through each and every one that happened on my shift and check 'properties'? Google and Yahoo in general aren't bad, but, they may have a link to my 'indiscrection' and should not be kept. Some 'cookies' to Yahoo may be needed and some files are jus on how to make the page look right (I think!)
Can anyone [here] help me cut this Gordian Knot? Thank you for your time and {web} space. Sign me: Frustrated and a bit scared. bye,

Hi, Thank you all for the info. I would 'view' at work and 'go to' at home. (WEBTV is a big computer in California and I an in (another state) with a browser and email dialed-up and converted to show on a TV screen.)Are you saying that if I deleted all temp internet files, reaching a site might be a tad slower but still act normal? Some seem to be gifs and jpegs for the (company's) main page and link to my email, etc. and some have specific expiration dates in the future. Possibly the latter are anti-spyware, etc that some one took time to save in this "temp" folder.
Am I safest (for the correct running of programs, not just getting caught) going thru and deleting one at a time anything that has no real 'Properties'. Were the two files mentioned in the original (Akamai.net and a.as-usfalkag.net) 'good guys', ie: anti-'bad guy' stuff? My looking on the net was a bit confusing for those two. I want to make it easy for the computer to do what it must and not remove anything someone actively looked for to have as a anti-bad guy tool.
If I am looking at a desk top that needed no password to access, is the "My Computer" for that station only or for many? Is the one station that needs my pasword unaffected by these files? My MSN (WEB)TV takes up enough of my time and becoming more computer literate beyond the scope of what I need to know at work, where they will train me in 'how to' and not 'how it did that' is not a high priority. My first job was with a TV station with BIG tubes and copper waveguides. Today it is all in a drawer's woth of space (not counting the gov'ts mandate that we convert to digital by (1909?). I am 'old school'. 8-) Thanks, again for time and space [here], bye 198.252.13.100 01:36, 30 November 2005 (UTC) (merged from below)

I've been trying to express pi as the limit as n goes to infinity, where n is the number of sides in a polygon. From what I've figured, it would be the ratio of the perimiter to the length of the longest diagonal. However, as I haven't used geometry for several years, I can't seem to express it mathematically. Please help and explain when neccessary. Thank you. -- frenchman113
First of all, I won't use diameter, because most polygons don't really have well-defined diameters. Even with regular polygons, if the number of sides is odd, diameters are tricky because they go from vertex to side, rather than vertex to vertex. I'll use a radius r instead (defined to be the length from the center to a vertex). So, for a regular polygon with n sides, each side of length s is subtended by an angle of
since there are n equal such angles. Using the law of cosines, the length s is given by
Solving and simplifying gives
The total perimeter of the polygon is Pins=ns. I may then consider the ratio Pins/2r:
This formula gives a lower bound for π, since it applies to a polygon inscribed in a circle (which has a shorter perimeter than the circle). If I consider a circle circumscribed by a polygon, using similar methods, I get
Thus I conclude that
and that
You can use this formula to get approximations of π using the half angle formulas. I believe that this is the method that Archimedes used. Hope that helps. - lethe talk 23:34, 29 November 2005 (UTC)
Have any neurological diseases (similar to Huntington's, Alzheimer's, or ALS) ever been cured?
Marianne
18:59, 29 November 2005 (UTC)
Most progressive neurological diseases are considered "incurable" due to either the limited ability of
neurons to repair themselves, or limited knowledge of the pathogenesis of these diseases. The closest thing to a cure I can cite is the limited success in treating
Parkinson's disease with the implantation of fetal
stem cells. The fact that this has happened at all is perhaps due to the relatively extensive knowledge of the biochemical basis for the symptoms of this disorder. See:
Fetal Brain Cell Transplants Benefit Some Patients with Parkinson's. Of course, the issue of fetal stem cell use is rife with ethical and religious questions, which will probably limit the usefulness of this method as a means of dealing with neurological disorders on a wide scale.

Electrically, what is the difference between an earth ground line and a neutral line in standard US utility systems? I ask because I am working with a 120VAC switching power supply that outputs 24VDC on one line and ground on the other, and a device I am using still requires a separate earth ground. The mfr even went so far as to design the supply to obstruct the ground pin on the outlet so it could not be used for this purpose. It was my understanding that the ground line and the neutral line were ultimately tied to the same place (a true earth ground like a copper pipe emerging from underground), and extend outward separately in the utility network as a safety mechanism, the ground being for device faults to shock the utility and not the user. If this is true, why do I not get +24V when measuring from the positive on the power supply to the earth ground line? Is this a sign of a bad ground? -- Jmeden2000 22:47, 29 November 2005 (UTC)

How would one go about calculating how long an orbit would be for a star with a different mass than the Sun? Is it as simple as if the sun had half the mass, a year would be twice as long? What about if the planet had a deferent mass? Would a planet with three quarters the mass of earth orbiting a star with half the mass of the sun at 1 AU have an orbit 2.7 years long? Or is it not that simple?
1 AU = 1 year 0.5 (star mass) / 1 year = 2 years 2 Years / .75 (planet mass) = 2.7 years

Two part question:
What type of instrument is used to measure the amount of EMR put out by a small appliance.
What types of flexible matierials block EMR (i.e., mesh, aluminum, kevlar)?
Thank you. Crillion 14:15, 30 November 2005 (UTC)
Here is the answer to the second question. Wire meshes are effective materials which shield objects from EMR. When an object is enclosed by a wire mesh or is inside a metal box(which can be of aluminium foil), electromagnetic waves cannot enter the mesh or the box. This can be easily observed. If you wrap your cell phone in a wire mesh, you can see the signal gradually decreasing in strength and eventually dying out. This is the technology used in coaxial cables used in short range communication to prevent external disturbances. Of course, wire meshes can not shield against EMR of high frequency such as light but is effective in the radio frequency range. When a source of electromagnetic radiation is enclosed in a wire mesh, there is no obstruction to the outgoing EMR. Vishnu Pradhan.V 17:57, 30 November 2005 (UTC)
