for some reason whenever I edit a question it duplicates the content at the bottom of the page instead of editing the origional? Are the developers having a bit of april fools fun with us?--205.188.116.74 00:14, 1 April 2006 (UTC)[reply]
On a hot summer's day, there's nothing better than an ice cold soda from a soda vending machine. These machines obviously act like refrigerators, lowering the temperature of the drink as cold as possible without freezing it.
But what happens when the vending machine is outdoors and the weather is below freezing? Is the vending machine essentially acting as a heater to bring the soda up above freezing temperature? How is this done? Odd when you think about it, buying a nice warm soda on a cold winter's day! Am I understanding things correctly here?Loomis51 00:26, 1 April 2006 (UTC)[reply]
Why are so many responses questioning the existence of outdoor vending machines? Where have you been living, under a rock? Trust me, they exist, and yes, even in sub-zero climates. As for the sugar explanation, haven't you ever heard of a popsicle? They freeze just fine in only slightly below freezing environments, and they're pretty much all sugar. Finally, as for the CO2/2atms argument, fine, I'll rephrase the question slightly: instead of a soda machine, make it a Snapple machine. No increased pressure, no carbonation.

A refrigerator usually is insulated, so as to keep the outside heat outside. That has the added bonus of keeping inside heat in, so if the temperature outside plunges far below what the vending machine is at, it'll take quite a while for the (relative) heat inside to leak outside. So even if there's no reversal of the refrigeration process, the machine will act like a thermos. kmccoy (talk) 01:46, 8 April 2006 (UTC)[reply]
Is the IUPAC name of polymethyl methacrylate (plexiglas) "poly(methyl 2-methylpropenoate)" or "poly(methyl 2-methylpropanoate)" or "poly(methyl 2-methylpropionate)" ? The article was recently changed. Thanks, AxelBoldt 01:02, 1 April 2006 (UTC)[reply]
I can see how crocodiles and hippos survived the Cretaceous metorite impact that killed the other dinosaurs, but what about elephants? They couldn't all have been in the water at the time it happened. And they were too big to be underground with the small ratty mammals from whence we evolved. Why do we still see elephants today? --Fuhghettaboutit 01:15, 1 April 2006 (UTC)[reply]
Also, I think you need a little more research if you think it was a Cambrian explosion. The Cambrian Period ended hundreds of millions of years before the dinosaurs existed. You're thiking of the K-T Boundary at the end of the Cretaceous Period, probably caused by the impact of a meteor or asteroid near what is now Chicxulub in Mexico. Elephants - as Loomis points out (and hippos too for that matter) evolved far later than that impact. Grutness...wha? 01:34, 1 April 2006 (UTC)[reply]
Once one accepts the dual nature of light as both a particle and a wave, then its clear that the inverse multiple ratio of the retrograde rotation of the planet Venus provides the best explanation for how one goes about punctuating an equilibrium. It's elementary. Loomis51 02:55, 1 April 2006 (UTC)[reply]
My first response was actually serious. To be honest I didn't actually take into account the "Cambrian Explosion" part because, to be honest, I'm not all that familiar with Earth's ancient past. I just answered with what I do know, which is, that elephants did not exist at the time of the dinosaurs. However, having given the matter further thought, I think the truest answer to the question is that the elephants survived underwater by using their trunks as snorkels.

The above question about maglev trains got me reading the Vactrain article. In the article, it says that these trains could potentially move at 4000-5000 mph. My question is about how this would affect the people in the train. Wouldn't they be subjected to rather high g forces and wouldn't that limit the number of people that could ride the train? I would think it would be at the very least uncomfortable for the elderly and small children. Dismas(talk) 01:19, 1 April 2006 (UTC)[reply]
However, slowing down at 1G (or even significant fractions thereof) would not be practical, as that would throw people out of their seats. My guess is that vactrains would a) accelerate at a lot less than 1G, and b) might use seats that swivel around mid-trip, so that the deceleration forces you back into your seat rather than out of it. But in any case, if you assume something quite mild like 0.3G, a train would take about 1040 miles to accelerate to 5000 mph. That sounds like a lot, but if you were travelling from New York to London the trip is about 3500 miles, so more than 1/3 of the trip would still be done at peak velocity. A trans-Pacific vactrain could potentially go even faster, or spend longer at vmax. --Robert Merkel
Hi all - I'm in the process of trying to get an article up to FA standard, and therefore trying to get rid of redlinks, even if it means writing stubs on them myself :) It's a geography article (The Catlins), and one of the redlinks is in the geology section, which talks about strike ridges. I have no idea what a strike ridge is, and can't seem to find a definition of them anywhere. Anyone know anything about them? Grutness...wha? 02:06, 1 April 2006 (UTC)[reply]
I work at a pharmacy and my boss told me today that some HIV drugs cause the virus count to be undetectable and someone getting an HIV test that has it and is on these drugs will show up negative in some cases. How is it possible to spread HIV if the viral count is undetectable and you show up negative on the test?
One possibly more ominous reason is that the drugs may not treat HIV at all, but may only interfere with a particular testing method for HIV antibodies. Such a drug would be harmful, not helpful. Hopefully, clinical studies would show no reduction in mortality with such drugs and they would therefore not be approved for general use. StuRat 09:11, 4 April 2006 (UTC)[reply]
I have been getting eye infections for the past year about every 3-5 weeks. I cant think of any reason why. I used to wear contacts, I stopped and I wear glasses now (because I thought it was because of the contacts), I dont touch my eyes, I threw away all my old eye drops, I wash my hands many times daily, and I have been to 9 different doctors and they act like its not a big deal. I told the last one, and he said "Well your eyes look perfectly healthy to me." That was a few days after I usd antibiotic eye drops. I got a convertable car about a year ago, I am not sure if its because I always drive with the top down and all the air that hits my eyes, but its driving me crazy. Any ideas or suggestions, or solutions would be appreciated.
Note that while a few cars are designed as convertibles, and have very little air flow into the passenger compartment during top-down driving, the majority are not. They essentially just cut the roof off a car with no thought to how that will effect the airflow. This can lead to major vortices of air, dust and bacteria whenever driven with the top down.

The windows of a commercial vessel's pilothouse often have a circular element inset into one or more panes of the windows of the pilothouse. This image from Google shows a pilothouse with two of these round objects visible. One in the window near the depthfinder, and one in a window in the background.
im guessing heat from the earth is used to generate steam, which turns turbines... it hink they tap into the sides of volcanos, i know theyre building a new one somewhere in the world currently 24.193.235.188 07:42, 1 April 2006 (UTC)[reply]
I'm attempting to construct a effect pedal for a guitar. I am having difficulty reading the circuit diagram. It indicates possibly a potentiometer by indicating a resistance and having an open arrow below it. The trouble I'm having is figuring out where the arrow connects to.
The arrows are at a certain level, and may be connected to the component on their left (or right). I have never come accross this sort of circuitry notation. (Also there is a dotted line in places, I am not sure what this means.) ---Brohan 06:12, 1 April 2006 (UTC)[reply]
I once read a theory that beneath the seabed in some areas of the "Bermuda Triangle" is an unusually large number of pockets of gasses that occasionally get released into the atmosphere. The result is that occasionally, the atmosphere that the planes are flying through does not contain enough oxygen for the internal combustion engines of prop-planes to function properly and so they stall. Perhaps not a spooky enough explanation, but a logical theory nonetheless. Loomis51 14:23, 2 April 2006 (UTC)[reply]
That's a reference to the theory that deposits of Methane hydrate are behind some disappeareances in the Bermuda Triangle. I saw a TV documentary on it that showed a very tiny amout of methane in the air can cause airplane engines (of the type in the airplanes that went missing) to die. Also demonstated was showing how a massive release of bubbles below a ship causes it to sink because it is heavier than the foam it is now siting on. Also was proof the deposits do exist there and many other places on/under the sea floor. What is lacking is evidence that these deposits sometimes thaw out all at once (although we do know it is possible). WAS 4.250 17:34, 2 April 2006 (UTC)[reply]
Hiya.im doing a project on marofat peas for my junior cert and im dead stuck.i need to know WHY they germinate faster when soaked and i need to know A.S.A.P!please help me as i cant find any relevent info. on any site!
I recently transferred (via ethernet cable) some files between two WinXP systems and later discovered about a third was corrupted. It may be that it was corrupted to begin with or it could be that something went wrong in the transfer (either way it doesn't matter, as the data in replaceable). I'm planning on moving about 100 GB of not-so-easily-replacable data from a WinXP system to another running Fedora Core 4. Is there are a program that will check the data integrity for me, during or after the transfer? --Username132 (talk) 15:16, 1 April 2006 (UTC)[reply]
