I was looking at the planet Venus February 12 with my 8 power birding binoculars. I thought I was seeing the cresent shape of it, with the bright part directed at the sun. Question: is it possible to resolve, i.e., see the round shape of Venus with such low power optics?

Within the last 3 months I have noticed that when I click my teeth together I sense an echo in my head. When I tap a finger on my head I also hear the same thing. I can tap all over the front, right side and rear of my head and hear it. It is not noticeable on the left side of my head. I asked my dentist about it and was told it was probably my sinuses. I asked my doctor about it and he had no idea. I am 68 years old and in good health. I am very active and have not noticed any other changes in my body. Any ideas?

I've been wondering for quite a while, if someone for some reason wanted to have their computer severely messed up, are there sites out there that a person can go to to intentionally get viruses?

What is the criteria for considering a place "haunted"? The article about ghosts says: 'They may wander around places they frequented when alive or where they died. Such places are known as "haunted";' However, nobody considers my house to be haunted, yet I'm sure that at least one person died here. I mean, humans have been living on this land for...a long time (each country has its own "earliest human habitation date", and I don't want to reveal where I live). What are the chances that nobody, in all these years, has died where my house is now? What are the chances that nobody (who is now dead), in all these years, has spent their entire life here? Why is my house not considered haunted, and why isn't every house in the world considered haunted? -- Bowlhover 05:01, 15 February 2006 (UTC)

spit) 08:50, 15 February 2006 (UTC)From the article Radio source SHGb02+14a: In the three times it has been detected, it has doppler shifted quite rapidly. This is presumably due to the motion of the source itself relative to us. A shift of 37 hertz per second (the maximum observed) would mean that the source was accelerating at around 8 m/s². If the civilization was sending out a signal from a home planet in orbit around the Sun, this would imply a pretty rapid rate of rotation. The Earth's acceleration about the Sun is much less.
With the understanding that I know very little about science and have an active imagination - has anyone given any consideration at all to the idea that the signal may come from an artificial body - a spaceship or a probe, basically? 8 m/s², unless I'm mistaken, is pretty close to acceleration due to Earth's gravity, the equivalent of 1 g; pretty reasonable for an artificial body containing human-style organic life. Does anyone know anything else about this signal, or if the possibility has even occured to anyone? Thanks for your time. -- Brasswatchman 09:06, 15 February 2006 (UTC)

I would like to know the source of the bulk vitamin C crystals one buys in health food stores please. -- Marvern 00:16, 16 February 2006 (UTC)Marvern
From the Vitamin C article. - Artificial L-enantiomer Vitamin C ( is produced from glucose by two main routes. The Reichstein process developed in the 1930s uses a single pre-fermentation followed by a purely chemical route. The more modern Two-Step fermentation process was originally developed in China in the 1960s, uses additional fermentation to replace part of the later chemical stages. Both processes yield approximately 60% vitamin C from the glucose feed.
In 1934, the Swiss pharmaceutical company Hoffmann-La Roche was the first to mass produce synthetic vitamin C, under the brand name of Redoxon. Main producers today are BASF/ Takeda, Roche, Merck and the China Pharmaceutical Group Ltd. of the People's Republic of China. China is slowly becoming the major world supplier as its prices undercut those of the US and European manufacturers. It is chemically identical to that produced in living things. [7].

Nutrition is the Wikipedia:Science collaboration of the week, and I've been doing the history section. I've got all the history of the vitamins and essential amino acids and most of the misc. details, but the Dietary minerals are driving me up the wall -- I've been googling for half an hour and I still don't know when calcium was recognized as an essential nutrient and by whom. I've decided that all I want to add is calcium and magnesium, because finding historical info on other minerals is too hard. -- James S. 00:59, 16 February 2006 (UTC)
The three criteria of an essential nutrient are that it be found in all healthy individuals, that complete elimination of it from the diet leads to harm, and that it cannot be synthesized from other substances in the body. No animal can transmute elements like Ca and Mg, so if we need to have it in our bodies it is an "essential nutrient". They have been known to be part of animal and human bones and bodies for at least 2 centuries, but it may be hard to identify who first found them in animals. alteripse 19:07, 16 February 2006 (UTC)

Is Gatorade really that much more effective at hydrating people than regular water? Isn't it just water with sugar, salt, and food coloring? -- JianLi 05:43, 16 February 2006 (UTC)
I think you may be confusing mg with mosm or mEq. Osmolality is determined by moles, not by wt. Isotonic fluids have about 300 mosm/kg, typically about 140-150 mEq/L of Na. Glucose is heavy but there is only 1 mosm per 18 mg. Gatorade is hypotonic, not hypertonic. alteripse 18:37, 16 February 2006 (UTC)
OK, here are details of Gatorade composition per L: 20 meq Na, 3 meq K, 50 g glu. In terms of salt content, this is very hypotonic. The site claims an osmolality of 330 mosm/L, which is nearly all derived from the 50g of glucose. However, this is gut osmolality, and most of the glucose will not be available to contribute to ECF osmolality as the Gatorade is digested and absorbed. alteripse 19:00, 16 February 2006 (UTC)
This question may sound silly but still its a doubt. Iron, calcium etc are essential nutriens for our body. So can we eat raw iron etc? why?
Yes, you can eat raw iron (like iron filings). Most of it would pass through you undigested but you dont need much and I suspect you might digest enough to meet your iron needs. Trace elements need to be in a digestible or absorbable chemical state, and usually in a palatable state as well. Few trace elements (except some of the metals) exist in a pure state. alteripse 12:08, 16 February 2006 (UTC)

Is the fiber really devoid of cotton dna, just as human hair lacks DNA? Does some sterilization or cleaning process remove cotton-cells from the fiber? Or is plant DNA just so dramatically different from human that it's easy to screen out in the testing process? Or something else I haven't considered? - Alecmconroy 14:24, 16 February 2006 (UTC)

Are there any evolutionary biologists that have theories about why humans developed the ability to cry? Does it have something to do with triggering feelings of empathy in others? - Quasipalm 21:17, 16 February 2006 (UTC)

What's more than a bit of a mystery to me is how a baby's parent or carer can just let the baby cry and cry and cry before finally getting around to responding to their needs. To me and a lot of people I know, a baby's crying is distressing, which suggests it is the baby's way of getting the parent's attention. They don't have language skills yet, so this is how they get to survive. The baby does not have the ability to recognise that some feeling they're having is not a life-threatening emergency but a temporary minor discomfort. The theory that "if you give into a baby's every cry, you'll only spoil it" is, in my opinion, one of the most misguided philosophies so-called civilisation has ever dreamt up.

My question is, how much power is being used when one 100watt bulb is on, compared to two 40watt bulbs
The unit of power is Watt but the commercial unit is KiloWatthour(commonly known as unit). The answer for your question:- If you use both bulbs for an hour the 100W bulb consumes 100/1000 * 1 KiloWatthour i.e. 0.1 KiloWatthour. In case of the 60W buld it consumes 60/1000*1.
So the formula for calculating the power consumed is:
Power of the devise (in Kilowatt's)*time (in hours).
Knowledge Seeker, I dont think you read the question. The question was how much power is being used............................ So the second anwer was right. I wrote kilowatt-hours you wrote watt-seconds. I think kilowatt-hours is the commercial and more widly used unit than watt-seconds. 61.17.240.135 05:57, 17 February 2006 (UTC)
Those efficiencies are horrible. I knew lamps were inefficient, but just a few % is really bad. Even the modern fluorescent lamps don't reach 10%. But I see my old friend the arc lamp is the most efficient at up to an impressive 22%. Funny how the the very first electric lamp design turns out to still be the best. Being a Dutchman I shouldn't be to happy about this because it's an Osram invention, not a Philips one (the bloody Germans got us beat again). But the article says efficiency is very low for the short-arc type. So are the long-arc ones the efficient ones? And where can I get one? Oh, hold on, aren't those the ones used in LCD projectors or something? The ones that cost a small fortune and last just a few thousand hours? DirkvdM 18:59, 17 February 2006 (UTC)
I've recently been uploading photos of various minerals I took at the Natural History Museum (see User:Aramgutang/Gallery), and while I took care to always note what it was that I was taking a picture of, there is one photo for which I can't find my notes (shown on the right). While identifying the mineral just from the photo is probably not possible, I'd appreciate it if someone could identify the crystal habit pictured, so that the photo can be used to illustrate something. The only thing I remember is that the crystals were artificially grown, if that helps. If not, I guess I could always put the picture in the crystal habit article, with a caption among the lines of "artificial growing of crystals can produce quite unique crystal habits".

I keep getting ants in my kitchen. I've tried some commercial repellants but the little buggers keep on coming back.
The article suggests chalk can help. How would I use it? They're coming up from under the house, through a couple of small openings. Do I just smear chalk around the openings?
Are there any other natural remedies that send ants back to their nest and keep them away for a long time?
I should mention that my duties as a committed Wikipedian preclude me from having a spotlessly clean kitchen 100% of the time, which may be part of the problem. JackofOz 10:58, 17 February 2006 (UTC)

I suggest POISON. Specifically, poison they will take back to the nest and kill off the entire colony. While having a spotless kitchen would keep the ant population down, it's impossible to avoid leaving a few food particles that would make a nice meal for an ant. Also, even if it was absolutely clean, ants would still occasionally sweep through the kitchen to check for food. I consider any ants to be unacceptable, so prefer "better living through toxic chemistry". Specifically, I recommend the MAXFORCE ANT GEL brand poison: [9] StuRat 17:22, 17 February 2006 (UTC)
When I said "repellants" in my question, I actually meant poison (it's supposed to get rid of them, so to me it is equivalent to repelling them - sorry, I wasn't thinking scientifically). The product I've used is Ant-Rid, which contains boron, and has all kinds of warnings about toxicity etc. It's described as a poison they will take back to the nest and kill off the entire colony, just like StuRat said. It seems to work for a little while, but then they just come back. Maybe it's a question of identifying them and getting a very specific poison (thanks Commander Keane). And I can see a lot of sense in removing all possible forms of temptation (but that means some form of discipline ... shudder.) Philosophically I have no issue with ants per se, but I just don't want them as my personal friends. I'm still curious about the chalk solution mentioned in the ants article. Any ideas?

I wish to find out because I think I've had my worst nightmare in a while. This place to share nightmares has to also be well-visited, btw.
This last night, I dreamed I was walking up Mid-Campus Drive to Hale Library (I usually ride my bike around campus however), and when I looked at the stopwatch I usually wear, it said 10:30, but the day looked like dawn before sun-up, at 6:30 in the morning. The sidewalks were crowded, but I saw no cars on the streets. As I was approaching Hale Library, I suddenly found myself in an ill-lit classroom. There was Nicole Peck, my Psychology instructor from the waking world, and she went over what pages to read and assignments to do, and handed us copies of half-sheets going over what we're to do by the next class day.
I had trouble reading it, so I tried to use a lighting contraption (I think was a lamp, but how about a flashlight?) It didn't light brightly enough so the girl sitting behind me said, "Hey, use your cellphone. The light on that should work." Then as I was taking out my cellphone, the instructor told the class, "Class, be sure to turn your cellphones to silent mode to conserve batteries! Also, don't drink any milk because if someone has to go to the hospital in the next 40 minutes..." (and something about the hospital not being able to service their patients too well because of a widespread power outage and something else...)
AND THEN...
I heard a brief city-wide siren, and a few explosions heard 1/2 second apart from each other. I looked out the window and saw what appeared to be missiles hitting the nearby base of Fort Riley (8-10 miles away). The teacher then announced, "Class, those appear to sound like Nuclear Blasts so..." although I don't remember what she said after that, what I remembered next was praying, "Please God, ensure my survival!" before waking up.
So,
1. I don't know where on Wikipedia would be a good place to share nightmares, so if there are such places, would you care to tell me, please?
2. If nukes were to strike Fort Riley, about 8-10 miles from Manhattan, how many seconds or minutes would I have to find a basement or suitable fallout shelter?
3. How much would Manhattan get damaged by a nuclear strike on Fort Riley? How badly would those in Manhattan get hurt?
4. If a teacher at my university got word that a nuclear strike on Fort Riley was imminent, what would s/he say to the class???

I having trouble with .svg images, and I don't know if it's because I'm on a mac or because of the images themselves.
For instance, if I want to copy Image:Svg.svg to my hard drive: I right click on the image and say "Save as". The filename that the mac wants to give the image is 'SVG.svg.png'. Since this is not a .png file (I assume), I erase the .png to make it save as a .svg, and change the File Type from 'PNG' to 'All formats'. However, when I try to open it, both in my image software and on my browser, I get an error with the implication that the image still has a .png tag somewhere in it and is corrupted. Specifically, if I open the image with firefox, I get the error
XML Parsing Error: not well-formed Location: file:///Users/asbestos/Desktop/Svg.svg Line Number 1, Column 1: ?PNG ^
Indeed, opening the image in a text editor I get a bunch of garbage with a 'PNG' tag at the top. I know, however, that the image's extension really is simply .svg, with no .png hiding anywhere.
Likewise, if I then try to upload the image to the commons, it says the image is corrupted.
Is my computer trying to turn the image into a .png, or is the image itself a .png masquerading as a .svg? I'm confused. — Asbestos | Talk (RFC) 14:17, 17 February 2006 (UTC)
OK I've worked out what's going on. When you click on the above link it takes you to a rasterised version of the svg. What you see is actually a png image. On the image page (lower left of the image) is a link to the actual svg file called svg.svg. If you save that file you get the real svg. Theresa Knott | Taste the Korn 15:25, 17 February 2006 (UTC)

I've got a wireless setup to share my Internet connection with some house mates. The distances aren't too big - 20 m at most, and the WiFi article mentions a range of 45 m. The furthest person didn't get any reception until I moved the transmitter less than 2 m, after which the signal jumped way up (then again, I don't know what sort of scales these things give - they're 'idiot proof' or something, meaning they simply don't quantify the info with a decent unit of measurement - bloody irritating). Now the change in distance was under 10%, so it can hardly be that. But first, there was a row of lp's in the line of the signal (actually right next to the transmitter). Does vinyl stop the radiation? Or steel reinforced walls maybe? Plastic or metal - what works as an isolator for this radiation? DirkvdM 20:08, 17 February 2006 (UTC)
The wireless phones are bad, too. Everything is bad. As I've said many times here, I find that a dual frequency (a+g) works best because it can work around those corners. -- Zeizmic 23:09, 17 February 2006 (UTC)

Hi, in August 2003 I purchased a Dell Inspiron 5100 laptop. Just lately, I've been having a problem where a clicking begins near where the hard drive is housed in the laptop. There doesn't seem to be a distinct cause as it happens both when I'm doing intensive video work and when there's only a desktop with minor background tasks running. When the clicking begins, the whole system grinds to an unusably slow pace, but a hard shut down and then booting back up fixes it at least temporarily. I've taken out the hard drive and it does sound like it could be making the clicking when I gently turn it over. The hard drive isdescribed as HARD DRIVE, 60GB, I, 9.5MM, 4.2K, FUJITSU, V40 on the dell site. I've looked there and on google but have found nothing describing this problem. I've backed up all the data I want off the drive in case its in its death throes (but this has been happening for ~1 week). I'm kind of stumped as to where to go from here. Should I bite the bullet and buy a new drive, hoping that fixes the problem? Or should I try something else first? Ideas? -Anonymous
P.S. If this is the wrong forum for this kind of question, where else should I try asking it? -Anonymous
Thanks for all the input. Unfortunately the entire computer is no longer under warranty and I live in Canada. Yeah, I also return to a bluescreen when I'm away for a while (I assume it did its clicking thing then died). Every time the clicking has happened while I'm near the computer I've shut it off manually. Mostly I just want to be 100% sure its the drive before I buy a new one. I'm 98% sure, as its not the CD/DVD drive (the sound's not coming from there) and there's no other moving parts AFAIK. The reason I have any doubt is that the computer slows to a crawl when it happens, which doesn't seem like something that should be associated with a hard drive failure to me. I'll try that diagnostic tool and see what I can see though. Thanks everyone. -Anonymous
Ok I just installed a SMART, and without the clicking happening the first thing it noticed is that after a cold boot the HD temp quickly rose to 47 deg C. The SMART tool by default sets off an alarm at anything over 42 deg C. Any processing beyond simple web browsing brought the temperature up by a couple more degrees. So, another question arises - is this a drive failing on its own or has it been baked to the point of failure by a faulty cooling system? I don't want to install a new drive only to bake that one too. To cover the simple stuff, the fan is free from clogging and the laptop is elevated ~ .5 cm off a hard surface by its feet for airflow. Where would you go from here? -Anonymous
On watching a recent (for the UK) episode of House, I'm left with a "why didn't they catch this much earlier?" feeling. The patient, it eventually transpired, had been exposed to a radioactive source which had killed his bone marrow, devastating his immune system which in turn caused or permitted all the other complex symptoms that had vexed the team for the first three quarters of the show. But, I'm left asking, wouldn't this have caused a huge drop in the patient's white cell count, something that would be apparent from his CBC. If ER is anything by which to judge, CBCs are thrown around whenever a patient has anything wrong with them (bar a few obvious meatcleaver-to-the-brain things). -- Finlay McWalter | Talk 03:07, 18 February 2006 (UTC)
Sometimes when I wake up in the morning and go back to sleep again, I enter a lucid dream while being fully aware that this is a dream. I could end the dream whenever I wanted. (By the way, I wasn't trying to induce the dream--it just occured.) Two questions regarding this:
-- Bowlhover 03:45, 18 February 2006 (UTC)
This is the most common time for people to be able to control their lucid dreams. In fact, you can be dreaming when more-or-less awake at this time. These dreams can be easily "killed" by just opening your eyes a fraction. Someone with more knowledge will be able to tell you more, but I suspect that the opening of the eyes triggers a change in brainwave rhythms. The tricky one - and still a controversial one - is lucid dreams at other times of the night. Even their very existence is questioned by many, and not a huge amount is known about them.

On the watertight compartments of a Chinese junk:
Have any scholar ever examined these compartments? If you want to build REAL watertight compartments, you need to make them almost as thick and water-tight as the ship's hull. It takes much less money if you only build "livingroom-like compartments" but they are useless if the ship's hull breaks as thin walls might not be able to withstand the water pressure at its lower part.
A small wooden boat may benefit from thin and cheap compartment walls. However, if you build a ship as large as Zheng He's "Treasure Ships", you need really thick and sturdy walls. Otherwise, the walls may break or move under increased water pressre. The inner walls may not need to fight the crushing waves, however, they still need to withstand static water pressure. -- Toytoy 04:03, 18 February 2006 (UTC)

I wont equation to how calculate economical thikness of insulation
I can't give a specific answer, but let me bring up some issues. This is an optimization problem, and the results will depend on how precisely you define the problem. If, for example, you choose to buy the amount of insulation which will pay for itself in the shortest time period, then you will want a relatively small amount of insulation, perhaps even none, if your home is already reasonably well insulated. If, on the other hand, you want to save the most amount of money total and plan to live there for many years, then more insulation might be in order. Factors that would go into the decision are the cost of insulation, the projected future cost of heating and air conditioning the home, the current level of insulation in the home, the effectiveness of the new insulation, the cost of installation, how long you expect to live in the home, projected future climate in the area, projected increase in resale value of a better insulated home, and the cost of the money used to pay for the insulation. The cost of money would be interest if you are borrowing it, or the opportunity cost, otherwise. StuRat 17:11, 18 February 2006 (UTC)

Have you considered therapy? Or is this for a book or something? Black Carrot 20:20, 18 February 2006 (UTC)
This question is not for a book, nor have I heard the song "suicide is painless". I really do want to die. (Sigh.) It depends on how well tomorrow turns out. I've been having a lot of stress lately, but my stress level tripled today due to a huge argument with a family member and extortion from that family member. Maybe slicing apart a major artery is the best way to die, since it's so easy to do and is not very painful (right?). Anyways, I haven't thought about consulting a doctor or having therapy, since this is a family issue.
My life has been very coincidental these days, too. While I'm struggling to deal with stress, my friend is struggling to deal with sadness--one of his close relatives died yesterday. -- Bowlhover 21:38, 18 February 2006 (UTC)

Bowlhover: please seek professional help. The problem is probably a chemical issue in your brain; things are not as bad as they look. There is help. -- Ashenai 00:05, 19 February 2006 (UTC)
Bowlhover, before you decide anything, think of this. You mention your friend's sadness ofer his recent loss. If you commit suicide, what will that do to him? He needs your support at this time - the last thing he would need is for you to die as well. Ashenai is right about internet diagnosis, but I suspect that you live in a nortehrn hemisphere country, and if so, you may well be feeling some of the effects of the lack of sunlight at this time of year, which can affect your brain chemistry and does increase perceived stress considerably (it's called Seasonal affective disorder). Don't be afraid or ashamed of asking for professional help - believe me, as a S.A.D. sufferer myself, it helps a lot. Grutness... wha? 00:33, 19 February 2006 (UTC)
I also agree with the right to die. But I profoundly disagree that it is anybody else's moral obligation to help them do so. If anything, we have a moral obligation to try to dissuade them. Proferring "helpful" suggestions about how to go about suicide in a forum like this is obscene, and could very well be illegal. JackofOz 00:40, 19 February 2006 (UTC)

I don't understand why people are saying this question should not be answered. Wikipedia is "The Free Encyclopedia", and information should be freely provided, no matter for what purpose. If someone asks how to make a bomb, we tell them to the best of our ability how to make a bomb. If someone asks what's a painless way to commit suicide, we tell them. Of course people will urge that person not to commit suicide, but there's no reason not to tell them how. It's pointless trying to keep general information like this a secret. The answer to the question is yes, there are (physically) painless ways to kill yourself, including cyanide, carbon monoxide, and drug overdose. — Keenan Pepper 03:53, 19 February 2006 (UTC)
I'll just mention my basic "sanity check" when I think about suicide: If there is anyone who would be upset, angry, irritated, inconvienced, alarmed, or otherwise emontionally (or even physically) harmed by me killing myself, then it is not right for me to do so. I could only kil myself if I was sure that it would harm no-one else. The reasoning for this is as follows: It is bad to cause unnecessary harm to anyone, myself or anyone else. It is not directly bad to suffer - it's unpleasent, but it may be useful, so it's not a obvious bad thing - so, my suffering should count less than anyone else's - killing myself is only an option if it would not harm anyone else. I don't know if this will be helpful. JesseW, the juggling janitor 09:56, 19 February 2006 (UTC)
I know the reference desk isn't the best place to ask for it, but I desperately need advice from different people. I've told my mom what I feel about the classes, but my dad usually doesn't listen to anybody--he has to have it his way. For things like this, there's usually no chance of dicussion/compromise Oh well, I'll try to talk to my dad about the classes anyways. (I wish my parents were physically abusing me. At least then I would have a good excuse for being dead.)
I spent today's three classes panicking and drawing up a detailed plan for suicide. It probably wouldn't be an exaggeration to say that today is the worst day of my life.
When I said "I don't share most peoples' interests", I meant that I don't like playing with other people, listening to music, drawing, going to the movies, or any other thing that most people my age like. In fact, I don't think I'm really interested in anything. That's why my life is boring.
As for clinical depression, I fit the symptoms. A depressed mood is common for me, and I definitely have a loss in interest or pleasure. I fit 6 out of the 12 symptoms listed after "loss of interest or pleasure". -- Bowlhover 04:34, 20 February 2006 (UTC)
While you're reading Wikipedia articles, also read anhedonia. My head just about exploded when someone mentioned that word to me a couple months ago -- it fit me so well.
Don't just talk to your dad about the classes -- see if you can't find a way to talk to him about the depression as well. His answers might seem useless, but if so, that doesn't mean he doesn't care, just that these are hard things to talk about and hard questions to answer.

Tell people you plan to kill yourself. You might think "oh, that's embarassing" or "what about the consequences" but if you are going to kill yourself, what does any of that matter. So tell people: police, teachers, anybody, everybody. Every piece of paper you turn in for homework or a test should have "I'm going to kill myself" on it. What's the worst that could happen? You're gonna kill youself anyway, right? So why not tell people? When they ask for a plan, make sure you have one or they won't believe you. Something that makes sense and doesn't sound like a joke. And be clear you absolutely have no plan or reason to take anyone with you when you leave this world. Don't be scared. Lots of people cry out for help in various ways. Saying "I'm going to kill myself" is so common a way of asking for help that it is often ignored. Moreso in the past than currently. Teachers, especially, are told to take it seriously. What NOT to do: one person put a gun to his head, blew his face off and lived, was hospitalized, months later was released, then successfuly killed himself. 4.250.138.180 17:16, 20 February 2006 (UTC)
Not really, the human body isn't built like that. Physical pain exists as a warning to the brain to stop doing something which will damage the rest of the body. That's why pain is so difficult to cope with. Emotional pain is no easier, especially as it has the habit of going on for longer: and it's much less clear to know what to do to make it go away, because it is the mind itself that is affected. All the same, it does go away: the only way you're be sure to be unhappy for the rest of your life is to end it now! You mentioned the Samaritans: this is their email address.

Leaving aside for the moment the problem that you're reluctant to talk to your dad abut this at all ('cos that's a hard problem that I don't have an answer to), and also leaving aside the worry that telling him your plan is a bad idea because he'd just try to talk you out of it, is part of the problem here that if you tell him you're depressed, or that this extra-school-on-Sunday thing is only making things worse, you're afraid he'll just say something like, "Quit whining, every adolescent goes through this sort of thing, I guess I did, but I got over it, what are you complaining about?" Anybody got any suggestions for Bowlhover for ways he could let his parents know this is serious, a way to say (with dignity) "Hey, pay attention to me, I need a little help here", without having to play the suicide card? -- Steve Summit ( talk) 16:50, 21 February 2006 (UTC)

Why all the things in the universe keep revolving, spinning, rotating? For example, electrons spin and revolve around nucleus; moons revolove around planets, which revolve around sun, which in turn revolves around the galactic centre.
Thanx Kainaw. I want to learn more about attraction and momentum "in this context".
what is minimum energy?
Drop a marble onto the side of a round mixing bowl (a half sphere is optimum). What are the chances the marble will roll back and forth in a straight line versus roll in a curved semi-circle? There are far more ways for gravity to cause objects to move in curved ways than straight ways. Far more types of spin velocities than zero spin velocity. Zero spin is just one of many spin velocities, why should it be preferred in the near frictionlessness of outter space? Where friction is important, like on Earth, objects lose rotational energy and stop spinning. Just like the marble loses energy due to friction with air and the mixing bowl and ends up in a minimum energy state sitting unmoving at the botton of the mixing bowl. 4.250.138.180 17:33, 20 February 2006 (UTC)
Can someone explain to me, why do the ears pop when a flight takes off?
You also get a similar effect by yawning, since the yawning mechnaism also involves the eustachian tubes. In fact, if the ears do not pop to equalise pressure when there is an internal/external imbalance it can cause pain and ringing in the ears. the best way to alleviate this is often to yawn, in the hope that it will unblock any problems in the Eustachian tube.

Is there a place where I could get the listings of un-explored areas of the Earth?
Due to imaginging from space, the surface of the earth is known completly to a scale of a meter or so. Knowledge of under the surface of the earth is largly lacking with mostly asumption. Some think the majority of life on Earth consists of bacteria beneath the surface. The most interesting vast expanses yet to be investigated are at the bottom of the oceans. Less vast are hundeds of square miles of equatorial jungle in Africa, South America, but especially north of Australia in mountainous areas. Under the ice in Antartica (both ice on land and over water) is currently yeilding surprises. 4.250.138.180 17:46, 20 February 2006 (UTC)
Just curious again: How long can our Earth keep rotating on its own axis? What would happen if suddenly our "green" earth stopped rotating or moving tomorrow? Will it affect normal life? How many species will get extinct and what steps should be taken by us? PS: I am not stupid!!!
Returning to the original question, the Earth will keep rotating as long as it exists, simply because there is nothing that would make it stop. As noted, the rate of rotation is slowing, but that's only due to tidal drag, whose effect is to bring different rotary motions into sync with each other. (Currently, the primary tidal drag is working to synchronize the Earth's rotation (the day) with the Moon's orbital motion around the Earth (the month).)
As noted, stopping the Earth's rotation would require a huge force, and it would also have to be directed in a way that does not occur in nature. But let us imagine that some powerful alien machine actually does this. The alien force acts equally on the different parts of the planet itself and on everything gravitationally bound to it and not in orbit: the atmosphere, the seas and rivers, the people, animals, buildings, and everything else. So everything comes to a gentle stop without being torn apart by stress just from the act of stopping. What then?
Well, the first thing is that the Earth's equatorial bulge (see Earth radius, figure of the Earth) would no longer be supported by centrifugal force. So every place in the tropics would suddenly be higher in elevation than before by at least 5 miles, and every place in the polar regions, lower by a similar amount. So the world's one ocean would divide into two, draining north and south into the polar regions and leaving all the continents joined by a wide strip of land (with lakes or seas where the deepest ocean was) along the equator. Meanwhile most or all of Antarctica, Canada, and Russia would find themselves underwater, as well as other places at similar latitudes.
There would be one particular latitude north and south where the sea level would stay the same, probably somewhere around 40 or 50 degrees; I don't know a quick way to work it out. Even at that latitude there might be massive coastal erosion as the ocean rushed by. Anywhere else, even if an entire country was not left underwater on the one hand or high and dry on the other, coastal cities still would be. My intuition says that these transformations would take something on the order of a few days' time, but I'm really just guessing there.
The conversion of the equatorial bulge into highlands would also put massive stress on the rocks underlying it. Over geological time, with no force supporting it any more, it would tend to collapse and make the Earth spherical; conversely, the polar regions would tend to rise. Which means there would be huge and numerous earthquakes throughout the tropics, and also underwater in the polar regions, perhaps causing tsunamis along on the new coasts. This process would probably begin immediately, but I have no idea how long it would go on; quite possibly for thousands of years. If it slumps a great deal more rapidly than that, then it might ameliorate the sea movements, but then the earthquakes would be even more devastating.
The third major destructive effect would be on the weather. With the Earth no longer rotating, the length of the solar day would now be a full year. So each part of the tropics in turn would now see the Sun shining down continuously for 6 months. Temperatures would climb greatly beyond the normal highs we see today. Conversely, with 6 months of night on the other side, frigid lows would be the rule. With no oceans in the tropics, there would be next to no humidity and I guess the entire band of land would become a desert. Farther away from the equator, the temperature differences would drive intense storms, perhaps permanent ones at some locations.
How many species would die? Most of them. The ones in the best position to survive would be some microorganisms, maybe some hardy plants in mid-latitudes, and any ocean-going creatures that managed to find something to live on. What steps to take? Find a way to negotiate with the aliens to get them not to do this!

Every now and then, here in the States on the local news, there will be a story, usually light filler, about two animals of different species hooking up and becoming best friends. Like a dog that is raising Cougar kittens for whatever reason. Or that snake that made a bond with a hamster rather than eating it. We see it with humans all the time, but it almost never happens with our animal brethren, so it is a matter of infinite fascination when this stuff comes to light.
So, my question is, what is this called, when two animals of different species that would otherwise not associate with each other inexplicably become, well, friends? Is there actual scientific study into this? What is such study called? Has any such study found out why or how they do this? Or is it just an asounding anomoly? -- Jeffrey O. Gustafson - Shazaam! - <*> 06:57, 19 February 2006 (UTC)
In the case of the snake and the hamster, it looks like the hamster was just too big for the snake to swallow, so it didn't even try. This is an interesting definition of a friend: "someone who finds you too large to swallow whole, so allows you to live". StuRat 19:32, 19 February 2006 (UTC)
Two cases I know of personally. (1) We once got from my wife's sister two rodents, a gerbil and a chinese hamster, that had been kept in the same cage together since both were rejected by their mothers. They wer both the runts of their respective litters. We placed their all-glass cage next to the one we already had two 2-year-old female rats in. The hamster and gerbil were continuous nest-builders. They would each build their own nest, live in it far a couple of days, and then rebuild it alll over. Before this time, we had never seen the rats build a nest. Within about three weeks, the rats were building a nest as well; but they shared theirs. My wife's psychology professor refered to what had happened to the rats as "cross-specific modelling". She did not seem to notice the bonding of the hamster and gerbil. (2) On a trip to the Valles Caldera in New Mexico, just west of Los Alamos, were talked to one of the Wildlife scientists, who had just photographically recorded a similar example of cross-specific behavior. A mother elk (wapiti) and her calf were grazing near a barbed wire fence. On the other side of the fence were two mares (female horses). A small pack of wolves crept towar the two elk. The mother elk brought the calf over to the fence, and the mares came to the other side, and hung their heads over the calf to shield it. The mother elk then chased after the wolves, supposedly giving them a few good kicks (no photos of kicks). She then returned to her calf and all four animals resumed grazing.-- 70.22.21.232 20:23, 19 February 2006 (UTC)
I took into consideration symbiosis, thus my qualification that the animals "would otherwise not associate with each other". Such relationships don't follow what clasifies as symbiosis, because neither organism is positively effected, nor negatively effected.

We have heard/read that bundling of software- especially Internet Explorer with windows is unfair for competitors of firms that do that. But why is Microsoft Office not considered as a bundle? If those software were sold seperately, Microsoft's share would be far less than what it is today. This bundling would have killed hundreds of start-ups (and the effect far more than IE-Windows bundle) but still no complaint of any such on Microsoft Office. Shouldn't Microsoft be forced to bring a'la carte pricing similar to law enforcing cable companies to sell channels individually? Whats worse, Google is also coming with something called Google Pack. If Microsoft's Office destroyed competition in PC, Google promises to do that to Internet related software. Should legal action be taken against Microsoft and Google?

User:Ashenai edited out several postst in a previous thread; Wikipedia:Reference_desk/Science#Painless_suicide. When I encountered this it was beyond repair, so the only solution I could think of to revert this vandalism was to post this again. So here it is.
Is there any easy, painless way to suicide? How about getting unconscious--is there any easy way to do that? I'm not trying to be stupid--these questions are very serious. -- Bowlhover 18:14, 18 February 2006 (UTC)
Have you considered therapy? Or is this for a book or something? Black Carrot 20:20, 18 February 2006 (UTC)
This question is not for a book, nor have I heard the song "suicide is painless". I really do want to die. (Sigh.) It depends on how well tomorrow turns out. I've been having a lot of stress lately, but my stress level tripled today due to a huge argument with a family member and extortion from that family member. Maybe slicing apart a major artery is the best way to die, since it's so easy to do and is not very painful (right?). Anyways, I haven't thought about consulting a doctor or having therapy, since this is a family issue.
My life has been very coincidental these days, too. While I'm struggling to deal with stress, my friend is struggling to deal with sadness--one of his close relatives died yesterday. -- Bowlhover 21:38, 18 February 2006 (UTC)
So far the part of the thread that was deleted.
Other than a family spat, we don't know why you feel this way. At one time I wanted more than anything to just be dead. It didn't work. I will always know that an angel intervened. Dead is forever. I know it seems like you'll never be happy again, but don't do this now. If you don't do this you will begin to feel better.-- Leah

Where can I buy them if they don't? Etc.

what is difference between operating system and kernel?and would like to know more about kernel?
It's a fuzzy question, but that's because the definitions are fuzzy. According to some people, the operating system is the kernel, namely, the one, privileged program that runs (usually in the processor's "system mode") and supervises the behavior of all the user-mode or application programs. Services typically performed by the kernel include: process scheduling, I/O, filesystem(s), date/time, and networking. Pretty often, though, the term "operating system" is used to encompass not just the kernel per se, but also those applications which are so closely associated with the system that it's effectively impossible to use it without them. Under Unix and Unix-like systems, those "part of the OS" applications would include the shells, the system daemons, and the standard toolkit programs such as cat, rm, sed, grep, etc. Under Windows, I've heard that MS Internet Explorer (though it's nominally an app) is variously integrated with and vital to the functioning of the rest of the system. -- Steve Summit ( talk) 18:36, 20 February 2006 (UTC)

The idea that race (or whatever other weird name you want to call it) doesn't exist is just wishful thinking on the part of some overly PC liberals. Beyond differences in skin color there is also hair color, hair texture, eye color, skull shape, and differences in disease susceptibility such as Tay-Sachs disease and sickle-cell anemia.

Hi.
I have this idea for a project that I want to try and get funding for:
I am wondering about the behaviour of the air we breath in an annular or ring laser tunnel.
Laser type: visible, green single mode.
Laser power: seventy to one hundred watts per laser.
Suppliers: Coherent or Laser Systems Europe.
Laser array: one thousand lasers in a collimated array to provide seventy thousand WATTS of visible laser energy in the green spectrum in a laser tunnel.
Laser tunnel: seventy thousand watts in a four inch (outside diameter) ring (three 14/16 inches inside diameter).
Laser tunnel length: two hundred feet.
Chamber conditions: vacume with no humans present in inmediate area of laser array.
Location: subsurface.
Question:
Since the laser tunnel is very high intensity will it serve as a pump?
In other words when I release regular air at one end of the tunnel will the inherent reflectivity of the laser tunnel serve as a tube transport for the ultra hot plasma that the normal air will become when exposed to seventy thousand watts of laser energy?
Will any of the super hot plasma reach the other end if the gas inside the tunnel is pushed by a second laser focused on the super hot gas inside the laser tunnel?
Since I notice that vaporized air or steam increases in reflectivity index as compared to regular breathable air at room temp.
Please forgive me for asking this question here since I tried other sites with science forums but users there assumed that I was of low I.Q. with questions like:
"Do you know thats a lot of power?"
"What are you using it for?"
"Do you know thats going to cost a lot of money?"
"Do you know that you are going to need lots of generators to run the lasers?"
Well I hope that some one that knows lasers or can point me to a place where I can find reflectivity indexes for breathable air and ultra high laser power tunnels reads this and helps me out?
Thank you.
R. E. Burrows.
Interesting.
Since even a twenty watt visible light laser will set paper on fire and a seventy thousand watt beam will melt metal.
I ask the question of why you say that the air will continue just being air?
Since that much energy when impacting any water droplets in the air will vaporize them and turn them into superheated steam.
On further reflection it looks like plasma is not a requirement since regular steam will have plenty of absorption.
Ok.
Where can I get the reflectivity index of steam?
Or a steam simulator that will show how steam perfoms when pushed by a laser?
The air inside the laser tunnel is a medium. The space around the outside of the laser tunnel is a vacume. The space inside the tunnel is normal air at sealevel pressure.( for a few pico seconds that the experiment lasts)until the effects of the laser are seen.
Normal air deflects a laser beam due to dust/moisture droplets.
So the tunnel walls need to be at the frequency that will produce a wake effect on electrons in the air at the absorption frequency.
I am wondering if any of the released air will manage to stay inside the tunnel and reach the other end when pushed by the laser inside the laser tunnel?
I noticed that the new laser diodes cavity were being made using air spaces to increase the reflectivity index and so reduce the required size for the resonant cavity when using multiple layer films.
Thank you.
R. E. Burrows.

when recording a casette in a tape recorder, should we keep the volume of the tape recorder at its maximum or at its minimum or exactly where should we keep? Will the sound enter the tape recorder through holes named MIC or through speaker itself?
Cheap cassette decks will not allow you to change the recording level and use an automatic gain control circuit to select a reasonable recording level. More expensive and/or older decks will often have manual record level controls and usually some level meters. The higher you set the level the better the signal to noise but (potentially) the more distortion. peaking at arround +3db seems fine on most decks i've tried. Plugwash 19:06, 27 February 2006 (UTC)

How does a sailboat sail toward the wind? I had trouble understanding the Wikipedia explaination. Can it sail directly into the wind, or does it need to aim at an angle? Thanx, Leah
Ah Hah! Got it! Thanks so much to yous, Steve, Chris, & Platy. The MacGregor discussion is really excellent. I went back to the Wiki explainations to find out why I had been confused. They were "sailing ships" and "sail." Yes, I think they can be fixed for introductory readers, by providing diagrams of how the wind interacts with the sails. Other than that, the Wikipedia explainations are quite good and very indepth. I could tell the Wiki writer had put much thought and work into the task. I still learned a lot.
When I saw it from Macgregor's "floor plans" I began to see the watermellon seed, one of the basic principles. One other thing is needed too, in Wikipedia. There needs to be several more pictures, particularly with labels of the different sail names, and what each does. (this one pulls the boat, this one squirts).As well, as a few diagrams of how the wind interacts with the sail. Macgregor's bird's eye view is priceless.
BluePlatypus, thanks especially for your summary. What you wrote really is the basics of sailing. You also explained the meanings of some important terms in a simple way I could understand, i.e. tacking, jibe, point of sail. Why don't you consider adding to many of the stubs on this topic? I've just moved near the ocean in Australia. Because of this discussion, now I think I might like to try this. Any suggestions for a good beginner boat? --Leah

My father recently informed me that he heard it from a government source person that the axial tilt of the earth recently increased by a couple of degrees due to the earthquake that caused the Sri Lankan Tsunami.

Thank you in advance! Aedenbow 18:40, 20 February 2006 (UTC)
"Highly unlikely" is too weak. This is arrant nonsense and should be slapped down as such. The amount of energy needed to change the Earth's rotation "by a couple of degrees" would be several orders of magnitude beyond what an earthquake releases. Even a very big quake. You're talking about a significant motion of the entire mass of the Earth, whereas a quake just moves a small section of the crust, and most of it not very far.
Charles P.'s response is correct as far as it goes, but confusing the real effect he talks about -- one detectable only by sensitive instruments -- with the sort of thing the original poster talked about is like confusing a grain of sand with a mountain.

BTW, this is for English class. We're studying the Inferno, and have to make up our own idea of hell. I'm not psychotic. Does anyone know where I can find current or definitive research on the subject of pain, both physical and psychological? It seems to me the tortures used by Dante in the Inferno were haphazard and unscientifically applied. I'm interested in three things: Different forms of pain and their effects on different people, the effects of pain over time (if you were really in excruciating pain for millenia, would you just get bored?), and how different pains combined interact. By pain, I mean everything from searing heat to exhaustion to dismemberment to terror, horror, despair and disgust. Anything you can find. Black Carrot 20:04, 20 February 2006 (UTC)
read Journey Into Madness : The True Story of Secret CIA Mind Control and Medical Abuse, by Gordon Thomas, Bantam, 1989, ISBN 0553053574 about Aziz al-Abub, trained by Americans, now a torturor of Americans.

Americans at Abu Ghraib are amateurs.
also read about Nazi death camps and their "experiments"

However, I think your teacher wants you to use your imagination, like Dante did, and come up with special tortures, like "being in Bob Zarbatani's gym class. Forever." Or something like that.

I appreciate the suggestions, but most of them are going in the wrong direction. I'm looking for actual factual information about the science of torture and the various methods available, so I can do a better job than he did. (And yeah, I realize he meant the punishment to fit the crime. They're still haphazardly applied.) The things I'm having the most difficulty finding out are:
Somewhat relatedly, suppose there was a chemical cocktail that induces pure pain from all the relevent sensory nerve receptors, could be varied in duration, and had no permanent physiological effects (aside from the psychological). Would such a substance be an effective form of torture or deterrent? I mean, could it supplement imprisonment as an effective crime deterrent? Say, half an hour of (physically harmless) unbearably agonising hell instead of six months in prison? I have to admit, it does sound good on paper. Tzarius 07:36, 22 February 2006 (UTC)
About physical pain: Severe pain makes you pass out. Lesser pain inflicted continuously eventually is ignored by the brain. Lesser pain inflicted discontinually produces psychosis wherein the "pain" becomes interpreted (along with many other aspects of reality, sometimes) as something other than pain. Pain is all in the mind. It is an interpretation of information. That's why buddists can burn themselves to death while sitting stoicly. To create real torment, you need to create emotional pain. You want the subject to be maximally aware (e.g. caffein), believe they are in control (you are "free"), yet their "errors" keep causing physical pain to themselves and a loved one (who is helpless). That's why "torture" doesn't work, but phychological techniques (that can include "minor" pains, especially fright) do. Anticipation is a grat tool. WAS 4.250 17:11, 22 February 2006 (UTC)
Can I tell the difference between the thought patterns of a 'sane' person and an 'insane' person? by thought patterns I mean, their thinking style, beliefs,etc. I have no knowledge of any objective 'meassurement' system regarding this...and also, even though I study psychology, I find it a little conceited that we label mental illnesses when in fact we don't even know what is 'the ideal behaviour' for a person, since that boils down to philosophy in the end. and I havent found any satisfactory concepts searching either.:S .-- Cosmic girl 22:18, 20 February 2006 (UTC)
ok... what I'm saying is that there's no way of telling objectively what is 'right' and what is 'wrong' in mental health matters, we may be able to say what is useful...but never what is in more accordance with reality.
for instance... a Descartes is seen as a great philosopher for coming up with the argument for philosophical skepticism...right? but then, if just a random person says that a demon may be fooling him into believing something, he's automatically a schizophrenic person... in this case, it's all about the confidence... then we have nietzches superman vs. people with 'antisocial personality disorder', then we have the mystics vs the schizophrenics and hypomaniacs...then we have the 'poetically melancholics' vs. the depressives. the pioneers vs. the ones with 'authority defiant dissorder'...am I the only one that sees the irony and stupidity in all this? I mean, what distinguishes one from the other, is it the confidence? it seems so... then there is perseverance as opposed to OCD, there's energy as opposed to hyperactivity... and I'm not an advocate of anti-psy. or scientology...I think they both suck actually... I just think we need a SCIENTIFIC model (like cognitive science) in the psychiatry and psychology classrooms...for real.-- Cosmic girl 23:00, 20 February 2006 (UTC)
I agree...we still have to take care of the mentally ill no matter if we don't know all about the field, or even if we don't know what's the 'ideal' for a person to be.-- Cosmic girl 02:06, 21 February 2006 (UTC)
by this question I was trying to gain some insight to the differences of the cognitive structures of a healthy person and of a mentally ill person...and you pointed it out ok. actually, I think your definition of mental illness is way better than the ones I've read in books.-- Cosmic girl 02:12, 21 February 2006 (UTC)
I am not a doctor, but I think psychologists and psychiatrists usually check the Diagnostic and Statistical Manual of Mental Disorders (DSM). This book defines various mental disorders by using checklists for symptoms of each disorder. By the way, for a historical perspective, consider that homosexuality was once considered a mental illness. -- Uthbrian ( talk) 00:55, 21 February 2006 (UTC) I knew that homosexuality was considered a mental illness..I don't think it is one, since it seems to be more voluntary than involuntary and also it doesn't make the person suffer , I mean, it doesn't go against the persons will if that person doesn't live in a society that condems it. but I do think that homosexuality goes against evolution more than it does against religion... but I have nothing against it, it's ok.-- Cosmic girl 02:16, 21 February 2006 (UTC)
Mental illness, in current medical science, is a "clinical diagnosis". What that means, is that a medical doctor (or specialist like a Psychiatrist) makes a diagnosis based on taking a history from the patient, family members, and examining the patient. There is no blood test, brain scan, or EEG to make a diagnosis of mental illness - it really is a judgement call. The DSM-IV can be used as a guide. (It was designed to define mental illnesses for the purpose of clinical research, so that the subjects would all be more or less similar.) Some mental illnesses (or symptoms) are easier to diagnose than others. Take for instance, psychosis, a symptom of schizophrenia. It could be defined as loss of connection to reality, such as hallucinations or false fixed beliefs. Whether someone is experiencing psychosis can be up to interpretation. Someone who believes that they are the Messiah and can bring about the end of the world is probably psychotic. However, someone who believes they can communicate with Jesus Christ may or may not be psychotic, depending on the particulars (such as their religion). - Cybergoth 03:33, 21 February 2006 (UTC)

I was looking at the planet Venus February 12 with my 8 power birding binoculars. I thought I was seeing the cresent shape of it, with the bright part directed at the sun. Question: is it possible to resolve, i.e., see the round shape of Venus with such low power optics?

Thank you for the answer. I went to the reference on the Phases of Venus as well. Rogelio
Within the last 3 months I have noticed that when I click my teeth together I sense an echo in my head. When I tap a finger on my head I also hear the same thing. I can tap all over the front, right side and rear of my head and hear it. It is not noticeable on the left side of my head. I asked my dentist about it and was told it was probably my sinuses. I asked my doctor about it and he had no idea. I am 68 years old and in good health. I am very active and have not noticed any other changes in my body. Any ideas?

I've been wondering for quite a while, if someone for some reason wanted to have their computer severely messed up, are there sites out there that a person can go to to intentionally get viruses? What is the easiest way for a person to screw their computer up via the internet? (exluding physically smashing it or other direct physical ways)
What is the criteria for considering a place "haunted"? The article about ghosts says: 'They may wander around places they frequented when alive or where they died. Such places are known as "haunted";' However, nobody considers my house to be haunted, yet I'm sure that at least one person died here. I mean, humans have been living on this land for...a long time (each country has its own "earliest human habitation date", and I don't want to reveal where I live). What are the chances that nobody, in all these years, has died where my house is now? What are the chances that nobody (who is now dead), in all these years, has spent their entire life here? Why is my house not considered haunted, and why isn't every house in the world considered haunted? -- Bowlhover 05:01, 15 February 2006 (UTC)

spit) 08:50, 15 February 2006 (UTC)From the article Radio source SHGb02+14a: In the three times it has been detected, it has doppler shifted quite rapidly. This is presumably due to the motion of the source itself relative to us. A shift of 37 hertz per second (the maximum observed) would mean that the source was accelerating at around 8 m/s². If the civilization was sending out a signal from a home planet in orbit around the Sun, this would imply a pretty rapid rate of rotation. The Earth's acceleration about the Sun is much less.
With the understanding that I know very little about science and have an active imagination - has anyone given any consideration at all to the idea that the signal may come from an artificial body - a spaceship or a probe, basically? 8 m/s², unless I'm mistaken, is pretty close to acceleration due to Earth's gravity, the equivalent of 1 g; pretty reasonable for an artificial body containing human-style organic life. Does anyone know anything else about this signal, or if the possibility has even occured to anyone? Thanks for your time. -- Brasswatchman 09:06, 15 February 2006 (UTC)

I would like to know the source of the bulk vitamin C crystals one buys in health food stores please. -- Marvern 00:16, 16 February 2006 (UTC)Marvern
From the Vitamin C article. - Artificial L-enantiomer Vitamin C ( is produced from glucose by two main routes. The Reichstein process developed in the 1930s uses a single pre-fermentation followed by a purely chemical route. The more modern Two-Step fermentation process was originally developed in China in the 1960s, uses additional fermentation to replace part of the later chemical stages. Both processes yield approximately 60% vitamin C from the glucose feed.
In 1934, the Swiss pharmaceutical company Hoffmann-La Roche was the first to mass produce synthetic vitamin C, under the brand name of Redoxon. Main producers today are BASF/ Takeda, Roche, Merck and the China Pharmaceutical Group Ltd. of the People's Republic of China. China is slowly becoming the major world supplier as its prices undercut those of the US and European manufacturers. It is chemically identical to that produced in living things. [7].

Nutrition is the Wikipedia:Science collaboration of the week, and I've been doing the history section. I've got all the history of the vitamins and essential amino acids and most of the misc. details, but the Dietary minerals are driving me up the wall -- I've been googling for half an hour and I still don't know when calcium was recognized as an essential nutrient and by whom. I've decided that all I want to add is calcium and magnesium, because finding historical info on other minerals is too hard. -- James S. 00:59, 16 February 2006 (UTC)
The three criteria of an essential nutrient are that it be found in all healthy individuals, that complete elimination of it from the diet leads to harm, and that it cannot be synthesized from other substances in the body. No animal can transmute elements like Ca and Mg, so if we need to have it in our bodies it is an "essential nutrient". They have been known to be part of animal and human bones and bodies for at least 2 centuries, but it may be hard to identify who first found them in animals. alteripse 19:07, 16 February 2006 (UTC)

Is Gatorade really that much more effective at hydrating people than regular water? Isn't it just water with sugar, salt, and food coloring? -- JianLi 05:43, 16 February 2006 (UTC)
I think you may be confusing mg with mosm or mEq. Osmolality is determined by moles, not by wt. Isotonic fluids have about 300 mosm/kg, typically about 140-150 mEq/L of Na. Glucose is heavy but there is only 1 mosm per 18 mg. Gatorade is hypotonic, not hypertonic. alteripse 18:37, 16 February 2006 (UTC)
OK, here are details of Gatorade composition per L: 20 meq Na, 3 meq K, 50 g glu. In terms of salt content, this is very hypotonic. The site claims an osmolality of 330 mosm/L, which is nearly all derived from the 50g of glucose. However, this is gut osmolality, and most of the glucose will not be available to contribute to ECF osmolality as the Gatorade is digested and absorbed. alteripse 19:00, 16 February 2006 (UTC)
This question may sound silly but still its a doubt. Iron, calcium etc are essential nutriens for our body. So can we eat raw iron etc? why?
Yes, you can eat raw iron (like iron filings). Most of it would pass through you undigested but you dont need much and I suspect you might digest enough to meet your iron needs. Trace elements need to be in a digestible or absorbable chemical state, and usually in a palatable state as well. Few trace elements (except some of the metals) exist in a pure state. alteripse 12:08, 16 February 2006 (UTC)

My question is: why doesn't the DNA from the cotton plant contaminate the sample? Is the cotton-like fiber some synthetic that never came from a living creature? Is the fiber really devoid of cotton dna, just as human hair lacks DNA? Does some sterilization or cleaning process remove cotton-cells from the fiber? Or is plant DNA just so dramatically different from human that it's easy to screen out in the testing process? Or something else I haven't considered? - Alecmconroy 14:24, 16 February 2006 (UTC)

Are there any evolutionary biologists that have theories about why humans developed the ability to cry? Does it have something to do with triggering feelings of empathy in others? - Quasipalm 21:17, 16 February 2006 (UTC)
The original purpose was definitely to wash irritants from the eyes. How this became used as a method of conveying one's current emotional state to others is a bit of a mystery to me, however. StuRat 21:48, 16 February 2006 (UTC)
What's more than a bit of a mystery to me is how a baby's parent or carer can just let the baby cry and cry and cry before finally getting around to responding to their needs. To me and a lot of people I know, a baby's crying is distressing, which suggests it is the baby's way of getting the parent's attention. They don't have language skills yet, so this is how they get to survive. The baby does not have the ability to recognise that some feeling they're having is not a life-threatening emergency but a temporary minor discomfort. The theory that "if you give into a baby's every cry, you'll only spoil it" is, in my opinion, one of the most misguided philosophies so-called civilisation has ever dreamt up. (That's it for my rant for today). JackofOz 05:43, 17 February 2006 (UTC)

My question is, how much power is being used when one 100watt bulb is on, compared to two 40watt bulbs
The unit of power is Watt but the commercial unit is KiloWatthour(commonly known as unit). The answer for your question:- If you use both bulbs for an hour the 100W bulb consumes 100/1000 * 1 KiloWatthour i.e. 0.1 KiloWatthour. In case of the 60W buld it consumes 60/1000*1.
So the formula for calculating the power consumed is:
Power of the devise (in Kilowatt's)*time (in hours).
Knowledge Seeker, I dont think you read the question. The question was how much power is being used............................ So the second anwer was right. I wrote kilowatt-hours you wrote watt-seconds. I think kilowatt-hours is the commercial and more widly used unit than watt-seconds. 61.17.240.135 05:57, 17 February 2006 (UTC)
Those efficiencies are horrible. I knew lamps were inefficient, but just a few % is really bad. Even the modern fluorescent lamps don't reach 10%. But I see my old friend the arc lamp is the most efficient at up to an impressive 22%. Funny how the the very first electric lamp design turns out to still be the best. Being a Dutchman I shouldn't be to happy about this because it's an Osram invention, not a Philips one (the bloody Germans got us beat again). But the article says efficiency is very low for the short-arc type. So are the long-arc ones the efficient ones? And where can I get one? Oh, hold on, aren't those the ones used in LCD projectors or something? The ones that cost a small fortune and last just a few thousand hours? DirkvdM 18:59, 17 February 2006 (UTC)
I've recently been uploading photos of various minerals I took at the Natural History Museum (see User:Aramgutang/Gallery), and while I took care to always note what it was that I was taking a picture of, there is one photo for which I can't find my notes (shown on the right). While identifying the mineral just from the photo is probably not possible, I'd appreciate it if someone could identify the crystal habit pictured, so that the photo can be used to illustrate something. The only thing I remember is that the crystals were artificially grown, if that helps. If not, I guess I could always put the picture in the crystal habit article, with a caption among the lines of "artificial growing of crystals can produce quite unique crystal habits".

I keep getting ants in my kitchen. I've tried some commercial repellants but the little buggers keep on coming back.
The article suggests chalk can help. How would I use it? They're coming up from under the house, through a couple of small openings. Do I just smear chalk around the openings?
Are there any other natural remedies that send ants back to their nest and keep them away for a long time?
I should mention that my duties as a committed Wikipedian preclude me from having a spotlessly clean kitchen 100% of the time, which may be part of the problem. JackofOz 10:58, 17 February 2006 (UTC)

I suggest POISON. Specifically, poison they will take back to the nest and kill off the entire colony. While having a spotless kitchen would keep the ant population down, it's impossible to avoid leaving a few food particles that would make a nice meal for an ant. Also, even if it was absolutely clean, ants would still occasionally sweep through the kitchen to check for food. I consider any ants to be unacceptable, so prefer "better living through toxic chemistry". Specifically, I recommend the MAXFORCE ANT GEL brand poison: [9] StuRat 17:22, 17 February 2006 (UTC)
When I said "repellants" in my question, I actually meant poison (it's supposed to get rid of them, so to me it is equivalent to repelling them - sorry, I wasn't thinking scientifically). The product I've used is Ant-Rid, which contains boron, and has all kinds of warnings about toxicity etc. It's described as a poison they will take back to the nest and kill off the entire colony, just like StuRat said. It seems to work for a little while, but then they just come back. Maybe it's a question of identifying them and getting a very specific poison (thanks Commander Keane). And I can see a lot of sense in removing all possible forms of temptation (but that means some form of discipline ... shudder.) Philosophically I have no issue with ants per se, but I just don't want them as my personal friends. I'm still curious about the chalk solution mentioned in the ants article. Any ideas?

I wish to find out because I think I've had my worst nightmare in a while. This place to share nightmares has to also be well-visited, btw.
This last night, I dreamed I was walking up Mid-Campus Drive to Hale Library (I usually ride my bike around campus however), and when I looked at the stopwatch I usually wear, it said 10:30, but the day looked like dawn before sun-up, at 6:30 in the morning. The sidewalks were crowded, but I saw no cars on the streets. As I was approaching Hale Library, I suddenly found myself in an ill-lit classroom. There was Nicole Peck, my Psychology instructor from the waking world, and she went over what pages to read and assignments to do, and handed us copies of half-sheets going over what we're to do by the next class day.
I had trouble reading it, so I tried to use a lighting contraption (I think was a lamp, but how about a flashlight?) It didn't light brightly enough so the girl sitting behind me said, "Hey, use your cellphone. The light on that should work." Then as I was taking out my cellphone, the instructor told the class, "Class, be sure to turn your cellphones to silent mode to conserve batteries! Also, don't drink any milk because if someone has to go to the hospital in the next 40 minutes..." (and something about the hospital not being able to service their patients too well because of a widespread power outage and something else...)
AND THEN...
I heard a brief city-wide siren, and a few explosions heard 1/2 second apart from each other. I looked out the window and saw what appeared to be missiles hitting the nearby base of Fort Riley (8-10 miles away). The teacher then announced, "Class, those appear to sound like Nuclear Blasts so..." although I don't remember what she said after that, what I remembered next was praying, "Please God, ensure my survival!" before waking up.
So,
1. I don't know where on Wikipedia would be a good place to share nightmares, so if there are such places, would you care to tell me, please?
2. If nukes were to strike Fort Riley, about 8-10 miles from Manhattan, how many seconds or minutes would I have to find a basement or suitable fallout shelter?
3. How much would Manhattan get damaged by a nuclear strike on Fort Riley? How badly would those in Manhattan get hurt?
4. If a teacher at my university got word that a nuclear strike on Fort Riley was imminent, what would s/he say to the class???

I having trouble with .svg images, and I don't know if it's because I'm on a mac or because of the images themselves.
For instance, if I want to copy Image:Svg.svg to my hard drive: I right click on the image and say "Save as". The filename that the mac wants to give the image is 'SVG.svg.png'. Since this is not a .png file (I assume), I erase the .png to make it save as a .svg, and change the File Type from 'PNG' to 'All formats'. However, when I try to open it, both in my image software and on my browser, I get an error with the implication that the image still has a .png tag somewhere in it and is corrupted. Specifically, if I open the image with firefox, I get the error
XML Parsing Error: not well-formed Location: file:///Users/asbestos/Desktop/Svg.svg Line Number 1, Column 1: ?PNG ^
Indeed, opening the image in a text editor I get a bunch of garbage with a 'PNG' tag at the top. I know, however, that the image's extension really is simply .svg, with no .png hiding anywhere.
Likewise, if I then try to upload the image to the commons, it says the image is corrupted.
Is my computer trying to turn the image into a .png, or is the image itself a .png masquerading as a .svg? I'm confused. — Asbestos | Talk (RFC) 14:17, 17 February 2006 (UTC)
OK I've worked out what's going on. When you click on the above link it takes you to a rasterised version of the svg. What you see is actually a png image. On the image page (lower left of the image) is a link to the actual svg file called svg.svg. If you save that file you get the real svg. Theresa Knott | Taste the Korn 15:25, 17 February 2006 (UTC)

The furthest person didn't get any reception until I moved the transmitter less than 2 m, after which the signal jumped way up (then again, I don't know what sort of scales these things give - they're 'idiot proof' or something, meaning they simply don't quantify the info with a decent unit of measurement - bloody irritating). Now the change in distance was under 10%, so it can hardly be that. But first, there was a row of lp's in the line of the signal (actually right next to the transmitter). Does vinyl stop the radiation? Or steel reinforced walls maybe? Plastic or metal - what works as an isolator for this radiation? DirkvdM 20:08, 17 February 2006 (UTC)
The wireless phones are bad, too. Everything is bad. As I've said many times here, I find that a dual frequency (a+g) works best because it can work around those corners. -- Zeizmic 23:09, 17 February 2006 (UTC)

Hi, in August 2003 I purchased a Dell Inspiron 5100 laptop. Just lately, I've been having a problem where a clicking begins near where the hard drive is housed in the laptop. There doesn't seem to be a distinct cause as it happens both when I'm doing intensive video work and when there's only a desktop with minor background tasks running. When the clicking begins, the whole system grinds to an unusably slow pace, but a hard shut down and then booting back up fixes it at least temporarily. I've taken out the hard drive and it does sound like it could be making the clicking when I gently turn it over. The hard drive isdescribed as HARD DRIVE, 60GB, I, 9.5MM, 4.2K, FUJITSU, V40 on the dell site. I've looked there and on google but have found nothing describing this problem. I've backed up all the data I want off the drive in case its in its death throes (but this has been happening for ~1 week). I'm kind of stumped as to where to go from here. Should I bite the bullet and buy a new drive, hoping that fixes the problem? Or should I try something else first? Ideas? -Anonymous
P.S. If this is the wrong forum for this kind of question, where else should I try asking it? -Anonymous
Thanks for all the input. Unfortunately the entire computer is no longer under warranty and I live in Canada. Yeah, I also return to a bluescreen when I'm away for a while (I assume it did its clicking thing then died). Every time the clicking has happened while I'm near the computer I've shut it off manually. Mostly I just want to be 100% sure its the drive before I buy a new one. I'm 98% sure, as its not the CD/DVD drive (the sound's not coming from there) and there's no other moving parts AFAIK. The reason I have any doubt is that the computer slows to a crawl when it happens, which doesn't seem like something that should be associated with a hard drive failure to me. I'll try that diagnostic tool and see what I can see though. Thanks everyone. -Anonymous
Ok I just installed a SMART, and without the clicking happening the first thing it noticed is that after a cold boot the HD temp quickly rose to 47 deg C. The SMART tool by default sets off an alarm at anything over 42 deg C. Any processing beyond simple web browsing brought the temperature up by a couple more degrees. So, another question arises - is this a drive failing on its own or has it been baked to the point of failure by a faulty cooling system? I don't want to install a new drive only to bake that one too. To cover the simple stuff, the fan is free from clogging and the laptop is elevated ~ .5 cm off a hard surface by its feet for airflow. Where would you go from here? -Anonymous
On watching a recent (for the UK) episode of House, I'm left with a "why didn't they catch this much earlier?" feeling. The patient, it eventually transpired, had been exposed to a radioactive source which had killed his bone marrow, devastating his immune system which in turn caused or permitted all the other complex symptoms that had vexed the team for the first three quarters of the show. But, I'm left asking, wouldn't this have caused a huge drop in the patient's white cell count, something that would be apparent from his CBC. If ER is anything by which to judge, CBCs are thrown around whenever a patient has anything wrong with them (bar a few obvious meatcleaver-to-the-brain things). -- Finlay McWalter | Talk 03:07, 18 February 2006 (UTC)
Sometimes when I wake up in the morning and go back to sleep again, I enter a lucid dream while being fully aware that this is a dream. I could end the dream whenever I wanted. (By the way, I wasn't trying to induce the dream--it just occured.) Two questions regarding this:
-- Bowlhover 03:45, 18 February 2006 (UTC)
This is the most common time for people to be able to control their lucid dreams. In fact, you can be dreaming when more-or-less awake at this time. These dreams can be easily "killed" by just opening your eyes a fraction. Someone with more knowledge will be able to tell you more, but I suspect that the opening of the eyes triggers a change in brainwave rhythms. The tricky one - and still a controversial one - is lucid dreams at other times of the night. Even their very existence is questioned by many, and not a huge amount is known about them.

On the watertight compartments of a Chinese junk:
Have any scholar ever examined these compartments? If you want to build REAL watertight compartments, you need to make them almost as thick and water-tight as the ship's hull. It takes much less money if you only build "livingroom-like compartments" but they are useless if the ship's hull breaks as thin walls might not be able to withstand the water pressure at its lower part.
A small wooden boat may benefit from thin and cheap compartment walls. However, if you build a ship as large as Zheng He's "Treasure Ships", you need really thick and sturdy walls. Otherwise, the walls may break or move under increased water pressre. The inner walls may not need to fight the crushing waves, however, they still need to withstand static water pressure. -- Toytoy 04:03, 18 February 2006 (UTC)

I wont equation to how calculate economical thikness of insulation
I can't give a specific answer, but let me bring up some issues. This is an optimization problem, and the results will depend on how precisely you define the problem. If, for example, you choose to buy the amount of insulation which will pay for itself in the shortest time period, then you will want a relatively small amount of insulation, perhaps even none, if your home is already reasonably well insulated. If, on the other hand, you want to save the most amount of money total and plan to live there for many years, then more insulation might be in order. Factors that would go into the decision are the cost of insulation, the projected future cost of heating and air conditioning the home, the current level of insulation in the home, the effectiveness of the new insulation, the cost of installation, how long you expect to live in the home, projected future climate in the area, projected increase in resale value of a better insulated home, and the cost of the money used to pay for the insulation. The cost of money would be interest if you are borrowing it, or the opportunity cost, otherwise. StuRat 17:11, 18 February 2006 (UTC)

Have you considered therapy? Or is this for a book or something? Black Carrot 20:20, 18 February 2006 (UTC)
This question is not for a book, nor have I heard the song "suicide is painless". I really do want to die. (Sigh.) It depends on how well tomorrow turns out. I've been having a lot of stress lately, but my stress level tripled today due to a huge argument with a family member and extortion from that family member. Maybe slicing apart a major artery is the best way to die, since it's so easy to do and is not very painful (right?). Anyways, I haven't thought about consulting a doctor or having therapy, since this is a family issue.
My life has been very coincidental these days, too. While I'm struggling to deal with stress, my friend is struggling to deal with sadness--one of his close relatives died yesterday. -- Bowlhover 21:38, 18 February 2006 (UTC)

Bowlhover: please seek professional help. The problem is probably a chemical issue in your brain; things are not as bad as they look. There is help. -- Ashenai 00:05, 19 February 2006 (UTC)
Bowlhover, before you decide anything, think of this. You mention your friend's sadness ofer his recent loss. If you commit suicide, what will that do to him? He needs your support at this time - the last thing he would need is for you to die as well. Ashenai is right about internet diagnosis, but I suspect that you live in a nortehrn hemisphere country, and if so, you may well be feeling some of the effects of the lack of sunlight at this time of year, which can affect your brain chemistry and does increase perceived stress considerably (it's called Seasonal affective disorder). Don't be afraid or ashamed of asking for professional help - believe me, as a S.A.D. sufferer myself, it helps a lot. Grutness... wha? 00:33, 19 February 2006 (UTC)
I also agree with the right to die. But I profoundly disagree that it is anybody else's moral obligation to help them do so. If anything, we have a moral obligation to try to dissuade them. Proferring "helpful" suggestions about how to go about suicide in a forum like this is obscene, and could very well be illegal. JackofOz 00:40, 19 February 2006 (UTC)

I don't understand why people are saying this question should not be answered. Wikipedia is "The Free Encyclopedia", and information should be freely provided, no matter for what purpose. If someone asks how to make a bomb, we tell them to the best of our ability how to make a bomb. If someone asks what's a painless way to commit suicide, we tell them. Of course people will urge that person not to commit suicide, but there's no reason not to tell them how. It's pointless trying to keep general information like this a secret. The answer to the question is yes, there are (physically) painless ways to kill yourself, including cyanide, carbon monoxide, and drug overdose. — Keenan Pepper 03:53, 19 February 2006 (UTC)
I'll just mention my basic "sanity check" when I think about suicide: If there is anyone who would be upset, angry, irritated, inconvienced, alarmed, or otherwise emontionally (or even physically) harmed by me killing myself, then it is not right for me to do so. I could only kil myself if I was sure that it would harm no-one else. The reasoning for this is as follows: It is bad to cause unnecessary harm to anyone, myself or anyone else. It is not directly bad to suffer - it's unpleasent, but it may be useful, so it's not a obvious bad thing - so, my suffering should count less than anyone else's - killing myself is only an option if it would not harm anyone else. I don't know if this will be helpful. JesseW, the juggling janitor 09:56, 19 February 2006 (UTC)
I know the reference desk isn't the best place to ask for it, but I desperately need advice from different people. I've told my mom what I feel about the classes, but my dad usually doesn't listen to anybody--he has to have it his way. For things like this, there's usually no chance of dicussion/compromise Oh well, I'll try to talk to my dad about the classes anyways. (I wish my parents were physically abusing me. At least then I would have a good excuse for being dead.)
I spent today's three classes panicking and drawing up a detailed plan for suicide. It probably wouldn't be an exaggeration to say that today is the worst day of my life.
When I said "I don't share most peoples' interests", I meant that I don't like playing with other people, listening to music, drawing, going to the movies, or any other thing that most people my age like. In fact, I don't think I'm really interested in anything. That's why my life is boring.
As for clinical depression, I fit the symptoms. A depressed mood is common for me, and I definitely have a loss in interest or pleasure. I fit 6 out of the 12 symptoms listed after "loss of interest or pleasure". -- Bowlhover 04:34, 20 February 2006 (UTC)
While you're reading Wikipedia articles, also read anhedonia. My head just about exploded when someone mentioned that word to me a couple months ago -- it fit me so well.
Don't just talk to your dad about the classes -- see if you can't find a way to talk to him about the depression as well. His answers might seem useless, but if so, that doesn't mean he doesn't care, just that these are hard things to talk about and hard questions to answer.

Tell people you plan to kill yourself. You might think "oh, that's embarassing" or "what about the consequences" but if you are going to kill yourself, what does any of that matter. So tell people: police, teachers, anybody, everybody. Every piece of paper you turn in for homework or a test should have "I'm going to kill myself" on it. What's the worst that could happen? You're gonna kill youself anyway, right? So why not tell people? When they ask for a plan, make sure you have one or they won't believe you. Something that makes sense and doesn't sound like a joke. And be clear you absolutely have no plan or reason to take anyone with you when you leave this world. Don't be scared. Lots of people cry out for help in various ways. Saying "I'm going to kill myself" is so common a way of asking for help that it is often ignored. Moreso in the past than currently. Teachers, especially, are told to take it seriously. What NOT to do: one person put a gun to his head, blew his face off and lived, was hospitalized, months later was released, then successfuly killed himself. 4.250.138.180 17:16, 20 February 2006 (UTC)
Not really, the human body isn't built like that. Physical pain exists as a warning to the brain to stop doing something which will damage the rest of the body. That's why pain is so difficult to cope with. Emotional pain is no easier, especially as it has the habit of going on for longer: and it's much less clear to know what to do to make it go away, because it is the mind itself that is affected. All the same, it does go away: the only way you're be sure to be unhappy for the rest of your life is to end it now! You mentioned the Samaritans: this is their email address.

Leaving aside for the moment the problem that you're reluctant to talk to your dad abut this at all ('cos that's a hard problem that I don't have an answer to), and also leaving aside the worry that telling him your plan is a bad idea because he'd just try to talk you out of it, is part of the problem here that if you tell him you're depressed, or that this extra-school-on-Sunday thing is only making things worse, you're afraid he'll just say something like, "Quit whining, every adolescent goes through this sort of thing, I guess I did, but I got over it, what are you complaining about?" Anybody got any suggestions for Bowlhover for ways he could let his parents know this is serious, a way to say (with dignity) "Hey, pay attention to me, I need a little help here", without having to play the suicide card? -- Steve Summit ( talk) 16:50, 21 February 2006 (UTC)

Why all the things in the universe keep revolving, spinning, rotating? For example, electrons spin and revolve around nucleus; moons revolove around planets, which revolve around sun, which in turn revolves around the galactic centre.
Thanx Kainaw. I want to learn more about attraction and momentum "in this context".
what is minimum energy?
Drop a marble onto the side of a round mixing bowl (a half sphere is optimum). What are the chances the marble will roll back and forth in a straight line versus roll in a curved semi-circle? There are far more ways for gravity to cause objects to move in curved ways than straight ways. Far more types of spin velocities than zero spin velocity. Zero spin is just one of many spin velocities, why should it be preferred in the near frictionlessness of outter space? Where friction is important, like on Earth, objects lose rotational energy and stop spinning. Just like the marble loses energy due to friction with air and the mixing bowl and ends up in a minimum energy state sitting unmoving at the botton of the mixing bowl. 4.250.138.180 17:33, 20 February 2006 (UTC)
Can someone explain to me, why do the ears pop when a flight takes off?
You also get a similar effect by yawning, since the yawning mechnaism also involves the eustachian tubes. In fact, if the ears do not pop to equalise pressure when there is an internal/external imbalance it can cause pain and ringing in the ears. the best way to alleviate this is often to yawn, in the hope that it will unblock any problems in the Eustachian tube.

Is there a place where I could get the listings of un-explored areas of the Earth?
Due to imaginging from space, the surface of the earth is known completly to a scale of a meter or so. Knowledge of under the surface of the earth is largly lacking with mostly asumption. Some think the majority of life on Earth consists of bacteria beneath the surface. The most interesting vast expanses yet to be investigated are at the bottom of the oceans. Less vast are hundeds of square miles of equatorial jungle in Africa, South America, but especially north of Australia in mountainous areas. Under the ice in Antartica (both ice on land and over water) is currently yeilding surprises. 4.250.138.180 17:46, 20 February 2006 (UTC)
Just curious again: How long can our Earth keep rotating on its own axis? What would happen if suddenly our "green" earth stopped rotating or moving tomorrow? Will it affect normal life? How many species will get extinct and what steps should be taken by us? PS: I am not stupid!!!
Returning to the original question, the Earth will keep rotating as long as it exists, simply because there is nothing that would make it stop. As noted, the rate of rotation is slowing, but that's only due to tidal drag, whose effect is to bring different rotary motions into sync with each other. (Currently, the primary tidal drag is working to synchronize the Earth's rotation (the day) with the Moon's orbital motion around the Earth (the month).)
As noted, stopping the Earth's rotation would require a huge force, and it would also have to be directed in a way that does not occur in nature. But let us imagine that some powerful alien machine actually does this. The alien force acts equally on the different parts of the planet itself and on everything gravitationally bound to it and not in orbit: the atmosphere, the seas and rivers, the people, animals, buildings, and everything else. So everything comes to a gentle stop without being torn apart by stress just from the act of stopping. What then?
Well, the first thing is that the Earth's equatorial bulge (see Earth radius, figure of the Earth) would no longer be supported by centrifugal force. So every place in the tropics would suddenly be higher in elevation than before by at least 5 miles, and every place in the polar regions, lower by a similar amount. So the world's one ocean would divide into two, draining north and south into the polar regions and leaving all the continents joined by a wide strip of land (with lakes or seas where the deepest ocean was) along the equator. Meanwhile most or all of Antarctica, Canada, and Russia would find themselves underwater, as well as other places at similar latitudes.
There would be one particular latitude north and south where the sea level would stay the same, probably somewhere around 40 or 50 degrees; I don't know a quick way to work it out. Even at that latitude there might be massive coastal erosion as the ocean rushed by. Anywhere else, even if an entire country was not left underwater on the one hand or high and dry on the other, coastal cities still would be. My intuition says that these transformations would take something on the order of a few days' time, but I'm really just guessing there.
The conversion of the equatorial bulge into highlands would also put massive stress on the rocks underlying it. Over geological time, with no force supporting it any more, it would tend to collapse and make the Earth spherical; conversely, the polar regions would tend to rise. Which means there would be huge and numerous earthquakes throughout the tropics, and also underwater in the polar regions, perhaps causing tsunamis along on the new coasts. This process would probably begin immediately, but I have no idea how long it would go on; quite possibly for thousands of years. If it slumps a great deal more rapidly than that, then it might ameliorate the sea movements, but then the earthquakes would be even more devastating.
The third major destructive effect would be on the weather. With the Earth no longer rotating, the length of the solar day would now be a full year. So each part of the tropics in turn would now see the Sun shining down continuously for 6 months. Temperatures would climb greatly beyond the normal highs we see today. Conversely, with 6 months of night on the other side, frigid lows would be the rule. With no oceans in the tropics, there would be next to no humidity and I guess the entire band of land would become a desert. Farther away from the equator, the temperature differences would drive intense storms, perhaps permanent ones at some locations.
How many species would die? Most of them. The ones in the best position to survive would be some microorganisms, maybe some hardy plants in mid-latitudes, and any ocean-going creatures that managed to find something to live on. What steps to take? Find a way to negotiate with the aliens to get them not to do this!

Every now and then, here in the States on the local news, there will be a story, usually light filler, about two animals of different species hooking up and becoming best friends. Like a dog that is raising Cougar kittens for whatever reason. Or that snake that made a bond with a hamster rather than eating it. We see it with humans all the time, but it almost never happens with our animal brethren, so it is a matter of infinite fascination when this stuff comes to light.
So, my question is, what is this called, when two animals of different species that would otherwise not associate with each other inexplicably become, well, friends? Is there actual scientific study into this? What is such study called? Has any such study found out why or how they do this? Or is it just an asounding anomoly? -- Jeffrey O. Gustafson - Shazaam! - <*> 06:57, 19 February 2006 (UTC)
In the case of the snake and the hamster, it looks like the hamster was just too big for the snake to swallow, so it didn't even try. This is an interesting definition of a friend: "someone who finds you too large to swallow whole, so allows you to live". StuRat 19:32, 19 February 2006 (UTC)
Two cases I know of personally. (1) We once got from my wife's sister two rodents, a gerbil and a chinese hamster, that had been kept in the same cage together since both were rejected by their mothers. They wer both the runts of their respective litters. We placed their all-glass cage next to the one we already had two 2-year-old female rats in. The hamster and gerbil were continuous nest-builders. They would each build their own nest, live in it far a couple of days, and then rebuild it alll over. Before this time, we had never seen the rats build a nest. Within about three weeks, the rats were building a nest as well; but they shared theirs. My wife's psychology professor refered to what had happened to the rats as "cross-specific modelling". She did not seem to notice the bonding of the hamster and gerbil. (2) On a trip to the Valles Caldera in New Mexico, just west of Los Alamos, were talked to one of the Wildlife scientists, who had just photographically recorded a similar example of cross-specific behavior. A mother elk (wapiti) and her calf were grazing near a barbed wire fence. On the other side of the fence were two mares (female horses). A small pack of wolves crept towar the two elk. The mother elk brought the calf over to the fence, and the mares came to the other side, and hung their heads over the calf to shield it. The mother elk then chased after the wolves, supposedly giving them a few good kicks (no photos of kicks). She then returned to her calf and all four animals resumed grazing.-- 70.22.21.232 20:23, 19 February 2006 (UTC)
I took into consideration symbiosis, thus my qualification that the animals "would otherwise not associate with each other". Such relationships don't follow what clasifies as symbiosis, because neither organism is positively effected, nor negatively effected. The snake and hamster deal is a little obvious, yes, but we all have heard of many other weird couplings that defy classification. Does no such classification exist, or does someone need to create one (0 0 Symbiosis?)? -- Jeffrey O. Gustafson - Shazaam! - <*> 04:37, 20 February 2006 (UTC)

If those software were sold seperately, Microsoft's share would be far less than what it is today. This bundling would have killed hundreds of start-ups (and the effect far more than IE-Windows bundle) but still no complaint of any such on Microsoft Office. Shouldn't Microsoft be forced to bring a'la carte pricing similar to law enforcing cable companies to sell channels individually? Whats worse, Google is also coming with something called Google Pack. If Microsoft's Office destroyed competition in PC, Google promises to do that to Internet related software. Should legal action be taken against Microsoft and Google?

User:Ashenai edited out several postst in a previous thread; Wikipedia:Reference_desk/Science#Painless_suicide. When I encountered this it was beyond repair, so the only solution I could think of to revert this vandalism was to post this again. So here it is.
Is there any easy, painless way to suicide? How about getting unconscious--is there any easy way to do that? I'm not trying to be stupid--these questions are very serious. -- Bowlhover 18:14, 18 February 2006 (UTC)
Have you considered therapy? Or is this for a book or something? Black Carrot 20:20, 18 February 2006 (UTC)
This question is not for a book, nor have I heard the song "suicide is painless". I really do want to die. (Sigh.) It depends on how well tomorrow turns out. I've been having a lot of stress lately, but my stress level tripled today due to a huge argument with a family member and extortion from that family member. Maybe slicing apart a major artery is the best way to die, since it's so easy to do and is not very painful (right?). Anyways, I haven't thought about consulting a doctor or having therapy, since this is a family issue.
My life has been very coincidental these days, too. While I'm struggling to deal with stress, my friend is struggling to deal with sadness--one of his close relatives died yesterday. -- Bowlhover 21:38, 18 February 2006 (UTC)
So far the part of the thread that was deleted.
Other than a family spat, we don't know why you feel this way. At one time I wanted more than anything to just be dead. It didn't work. I will always know that an angel intervened. Dead is forever. I know it seems like you'll never be happy again, but don't do this now. If you don't do this you will begin to feel better.-- Leah

Where can I buy them if they don't? Etc.

what is difference between operating system and kernel?and would like to know more about kernel?
It's a fuzzy question, but that's because the definitions are fuzzy. According to some people, the operating system is the kernel, namely, the one, privileged program that runs (usually in the processor's "system mode") and supervises the behavior of all the user-mode or application programs. Services typically performed by the kernel include: process scheduling, I/O, filesystem(s), date/time, and networking. Pretty often, though, the term "operating system" is used to encompass not just the kernel per se, but also those applications which are so closely associated with the system that it's effectively impossible to use it without them. Under Unix and Unix-like systems, those "part of the OS" applications would include the shells, the system daemons, and the standard toolkit programs such as cat, rm, sed, grep, etc. Under Windows, I've heard that MS Internet Explorer (though it's nominally an app) is variously integrated with and vital to the functioning of the rest of the system. -- Steve Summit ( talk) 18:36, 20 February 2006 (UTC)

The idea that race (or whatever other weird name you want to call it) doesn't exist is just wishful thinking on the part of some overly PC liberals. Beyond differences in skin color there is also hair color, hair texture, eye color, skull shape, and differences in disease susceptibility such as Tay-Sachs disease and sickle-cell anemia.

Hi.
I have this idea for a project that I want to try and get funding for:
I am wondering about the behaviour of the air we breath in an annular or ring laser tunnel.
Laser type: visible, green single mode.
Laser power: seventy to one hundred watts per laser.
Suppliers: Coherent or Laser Systems Europe.
Laser array: one thousand lasers in a collimated array to provide seventy thousand WATTS of visible laser energy in the green spectrum in a laser tunnel.
Laser tunnel: seventy thousand watts in a four inch (outside diameter) ring (three 14/16 inches inside diameter).
Laser tunnel length: two hundred feet.
Chamber conditions: vacume with no humans present in inmediate area of laser array.
Location: subsurface.
Question:
Since the laser tunnel is very high intensity will it serve as a pump?
In other words when I release regular air at one end of the tunnel will the inherent reflectivity of the laser tunnel serve as a tube transport for the ultra hot plasma that the normal air will become when exposed to seventy thousand watts of laser energy?
Will any of the super hot plasma reach the other end if the gas inside the tunnel is pushed by a second laser focused on the super hot gas inside the laser tunnel?
Since I notice that vaporized air or steam increases in reflectivity index as compared to regular breathable air at room temp.
Please forgive me for asking this question here since I tried other sites with science forums but users there assumed that I was of low I.Q. with questions like:
"Do you know thats a lot of power?"
"What are you using it for?"
"Do you know thats going to cost a lot of money?"
"Do you know that you are going to need lots of generators to run the lasers?"
Well I hope that some one that knows lasers or can point me to a place where I can find reflectivity indexes for breathable air and ultra high laser power tunnels reads this and helps me out?
Thank you.
R. E. Burrows.
Interesting.
Since even a twenty watt visible light laser will set paper on fire and a seventy thousand watt beam will melt metal.
I ask the question of why you say that the air will continue just being air?
Since that much energy when impacting any water droplets in the air will vaporize them and turn them into superheated steam.
On further reflection it looks like plasma is not a requirement since regular steam will have plenty of absorption.
Ok.
Where can I get the reflectivity index of steam?
Or a steam simulator that will show how steam perfoms when pushed by a laser?
The air inside the laser tunnel is a medium. The space around the outside of the laser tunnel is a vacume. The space inside the tunnel is normal air at sealevel pressure.( for a few pico seconds that the experiment lasts)until the effects of the laser are seen.
Normal air deflects a laser beam due to dust/moisture droplets.
So the tunnel walls need to be at the frequency that will produce a wake effect on electrons in the air at the absorption frequency.
I am wondering if any of the released air will manage to stay inside the tunnel and reach the other end when pushed by the laser inside the laser tunnel?
I noticed that the new laser diodes cavity were being made using air spaces to increase the reflectivity index and so reduce the required size for the resonant cavity when using multiple layer films.
Thank you.
R. E. Burrows.

when recording a casette in a tape recorder, should we keep the volume of the tape recorder at its maximum or at its minimum or exactly where should we keep? Will the sound enter the tape recorder through holes named MIC or through speaker itself?
Cheap cassette decks will not allow you to change the recording level and use an automatic gain control circuit to select a reasonable recording level. More expensive and/or older decks will often have manual record level controls and usually some level meters. The higher you set the level the better the signal to noise but (potentially) the more distortion. peaking at arround +3db seems fine on most decks i've tried. Plugwash 19:06, 27 February 2006 (UTC)

How does a sailboat sail toward the wind? I had trouble understanding the Wikipedia explaination. Can it sail directly into the wind, or does it need to aim at an angle? Thanx, Leah
Ah Hah! Got it! Thanks so much to yous, Steve, Chris, & Platy. The MacGregor discussion is really excellent. I went back to the Wiki explainations to find out why I had been confused. They were "sailing ships" and "sail." Yes, I think they can be fixed for introductory readers, by providing diagrams of how the wind interacts with the sails. Other than that, the Wikipedia explainations are quite good and very indepth. I could tell the Wiki writer had put much thought and work into the task. I still learned a lot.
When I saw it from Macgregor's "floor plans" I began to see the watermellon seed, one of the basic principles. One other thing is needed too, in Wikipedia. There needs to be several more pictures, particularly with labels of the different sail names, and what each does. (this one pulls the boat, this one squirts).As well, as a few diagrams of how the wind interacts with the sail. Macgregor's bird's eye view is priceless.
BluePlatypus, thanks especially for your summary. What you wrote really is the basics of sailing. You also explained the meanings of some important terms in a simple way I could understand, i.e. tacking, jibe, point of sail. Why don't you consider adding to many of the stubs on this topic? I've just moved near the ocean in Australia. Because of this discussion, now I think I might like to try this. Any suggestions for a good beginner boat? --Leah

My father recently informed me that he heard it from a government source person that the axial tilt of the earth recently increased by a couple of degrees due to the earthquake that caused the Sri Lankan Tsunami.

Thank you in advance! Aedenbow 18:40, 20 February 2006 (UTC)
"Highly unlikely" is too weak. This is arrant nonsense and should be slapped down as such. The amount of energy needed to change the Earth's rotation "by a couple of degrees" would be several orders of magnitude beyond what an earthquake releases. Even a very big quake. You're talking about a significant motion of the entire mass of the Earth, whereas a quake just moves a small section of the crust, and most of it not very far.
Charles P.'s response is correct as far as it goes, but confusing the real effect he talks about -- one detectable only by sensitive instruments -- with the sort of thing the original poster talked about is like confusing a grain of sand with a mountain.

BTW, this is for English class. We're studying the Inferno, and have to make up our own idea of hell. I'm not psychotic. Does anyone know where I can find current or definitive research on the subject of pain, both physical and psychological? It seems to me the tortures used by Dante in the Inferno were haphazard and unscientifically applied. I'm interested in three things: Different forms of pain and their effects on different people, the effects of pain over time (if you were really in excruciating pain for millenia, would you just get bored?), and how different pains combined interact. By pain, I mean everything from searing heat to exhaustion to dismemberment to terror, horror, despair and disgust. Anything you can find. Black Carrot 20:04, 20 February 2006 (UTC)
read Journey Into Madness : The True Story of Secret CIA Mind Control and Medical Abuse, by Gordon Thomas, Bantam, 1989, ISBN 0553053574 about Aziz al-Abub, trained by Americans, now a torturor of Americans.

Americans at Abu Ghraib are amateurs.
also read about Nazi death camps and their "experiments"

However, I think your teacher wants you to use your imagination, like Dante did, and come up with special tortures, like "being in Bob Zarbatani's gym class. Forever." Or something like that.

I appreciate the suggestions, but most of them are going in the wrong direction. I'm looking for actual factual information about the science of torture and the various methods available, so I can do a better job than he did. (And yeah, I realize he meant the punishment to fit the crime. They're still haphazardly applied.) The things I'm having the most difficulty finding out are:
Somewhat relatedly, suppose there was a chemical cocktail that induces pure pain from all the relevent sensory nerve receptors, could be varied in duration, and had no permanent physiological effects (aside from the psychological). Would such a substance be an effective form of torture or deterrent? I mean, could it supplement imprisonment as an effective crime deterrent? Say, half an hour of (physically harmless) unbearably agonising hell instead of six months in prison? I have to admit, it does sound good on paper. Tzarius 07:36, 22 February 2006 (UTC)
About physical pain: Severe pain makes you pass out. Lesser pain inflicted continuously eventually is ignored by the brain. Lesser pain inflicted discontinually produces psychosis wherein the "pain" becomes interpreted (along with many other aspects of reality, sometimes) as something other than pain. Pain is all in the mind. It is an interpretation of information. That's why buddists can burn themselves to death while sitting stoicly. To create real torment, you need to create emotional pain. You want the subject to be maximally aware (e.g. caffein), believe they are in control (you are "free"), yet their "errors" keep causing physical pain to themselves and a loved one (who is helpless). That's why "torture" doesn't work, but phychological techniques (that can include "minor" pains, especially fright) do. Anticipation is a grat tool. WAS 4.250 17:11, 22 February 2006 (UTC)
Can I tell the difference between the thought patterns of a 'sane' person and an 'insane' person? by thought patterns I mean, their thinking style, beliefs,etc. I have no knowledge of any objective 'meassurement' system regarding this...and also, even though I study psychology, I find it a little conceited that we label mental illnesses when in fact we don't even know what is 'the ideal behaviour' for a person, since that boils down to philosophy in the end. and I havent found any satisfactory concepts searching either.:S .-- Cosmic girl 22:18, 20 February 2006 (UTC)
ok... what I'm saying is that there's no way of telling objectively what is 'right' and what is 'wrong' in mental health matters, we may be able to say what is useful...but never what is in more accordance with reality.
for instance... a Descartes is seen as a great philosopher for coming up with the argument for philosophical skepticism...right? but then, if just a random person says that a demon may be fooling him into believing something, he's automatically a schizophrenic person... in this case, it's all about the confidence... then we have nietzches superman vs. people with 'antisocial personality disorder', then we have the mystics vs the schizophrenics and hypomaniacs...then we have the 'poetically melancholics' vs. the depressives. the pioneers vs. the ones with 'authority defiant dissorder'...am I the only one that sees the irony and stupidity in all this? I mean, what distinguishes one from the other, is it the confidence? it seems so... then there is perseverance as opposed to OCD, there's energy as opposed to hyperactivity... and I'm not an advocate of anti-psy. or scientology...I think they both suck actually... I just think we need a SCIENTIFIC model (like cognitive science) in the psychiatry and psychology classrooms...for real.-- Cosmic girl 23:00, 20 February 2006 (UTC)
I agree...we still have to take care of the mentally ill no matter if we don't know all about the field, or even if we don't know what's the 'ideal' for a person to be.-- Cosmic girl 02:06, 21 February 2006 (UTC)
by this question I was trying to gain some insight to the differences of the cognitive structures of a healthy person and of a mentally ill person...and you pointed it out ok. actually, I think your definition of mental illness is way better than the ones I've read in books.-- Cosmic girl 02:12, 21 February 2006 (UTC)
I am not a doctor, but I think psychologists and psychiatrists usually check the Diagnostic and Statistical Manual of Mental Disorders (DSM). This book defines various mental disorders by using checklists for symptoms of each disorder. By the way, for a historical perspective, consider that homosexuality was once considered a mental illness. -- Uthbrian ( talk) 00:55, 21 February 2006 (UTC) I knew that homosexuality was considered a mental illness..I don't think it is one, since it seems to be more voluntary than involuntary and also it doesn't make the person suffer , I mean, it doesn't go against the persons will if that person doesn't live in a society that condems it. but I do think that homosexuality goes against evolution more than it does against religion... but I have nothing against it, it's ok.-- Cosmic girl 02:16, 21 February 2006 (UTC)
Mental illness, in current medical science, is a "clinical diagnosis". What that means, is that a medical doctor (or specialist like a Psychiatrist) makes a diagnosis based on taking a history from the patient, family members, and examining the patient. There is no blood test, brain scan, or EEG to make a diagnosis of mental illness - it really is a judgement call. The DSM-IV can be used as a guide. (It was designed to define mental illnesses for the purpose of clinical research, so that the subjects would all be more or less similar.) Some mental illnesses (or symptoms) are easier to diagnose than others. Take for instance, psychosis, a symptom of schizophrenia. It could be defined as loss of connection to reality, such as hallucinations or false fixed beliefs. Whether someone is experiencing psychosis can be up to interpretation. Someone who believes that they are the Messiah and can bring about the end of the world is probably psychotic. However, someone who believes they can communicate with Jesus Christ may or may not be psychotic, depending on the particulars (such as their religion). - Cybergoth 03:33, 21 February 2006 (UTC)
