If you are not exposed to radioiodine it's useless, but that's not the real irony here. As a hint, the joke wouldn't work if they used sodium iodide.

"There are only three macronutrients, so if the weight isn't a carb/protein/fat, then what is it?" Bone, fibre, minerals, anything else that was round the place at the time.

Can I just ask about something that seems to have been missed here.? "It won’t. We haven’t even discovered any extra-terrestrial life out there yet. And if this is the case, then I’m sure God would understand as He is fair and merciful. " I'd just like to ask on behalf of the people in Japan, New Zealand, etc etc ad nauseam. Are you sure about the "fair and merciful" bit?

I take that as a "No" then.

I'm not sure about the laid back state of all chemists, but spectroscopists know exactly how excited they should be (as a function of available energy).

Does anyone else see the irony in taking potassium iodide tablets "to prevent radiation damage"?

As far as I can tell, at the moment they pump oil out of the ground in Libya and sell it at the going rate on the international market. Much of the money goes to Gadaffi and his entourage. A lot of the oil is bought by the US. If the government in Libya changes ( for whatever reason) the oil will still get pumped and sold. A lot of that will still be bought by the US. There is a small difference in that the companies doing the drilling etc might be US owned rather than state owned (i.e. Gadaffi's back pocket owned) but the direct difference in the availability of the oil will be minimal. They might decide to pump more oil and thus make a lot more money (and slightly reduce the world oil price) but OPEC would probably take action to compensate for most of that change. However there's a real possibility that, without their current government, the people there will be a lot happier and might get a better share of the money. (Of course, they might just swap one bad government for another)

"People claiming paranormal abilities are either deluded or are scam artists." And I think we can work out which one applies here. http://www.schizophrenia.com:8080/jiveforums/message.jspa?messageID=282041#282041

"Um, yes it is. If you have brown eyes for example, that means you have the specific "brown eyes" (dominant) gene. The question then follows that if homosexuality is " There is no "brown eye" gene ( except in elementary level text books). Even wiki has a better grasp of it than you. The wiki page clearly says "The genetics of eye color are complicated, and color is determined by multiple genes." "Trust me, if it was discovered that homosexuality was indeed genetic, everyone would know about it by now!" Everybody except one does. You are that one. "Once again, correlation not causation. And never forget a cardinal rule of science. . "it only takes the sighting of one black swan to know that not all swans are white." By that argument, sex isn't the cause of children. Not all sex leads to children (and according to some minority views, not all children were caused by sex- but that's another issue).

England doesn't have regions or states. Do you mean county?

Potatoes are roughly 20% carbohydrate of which almost all is starch. About 1% of the weight is composed of sugars and I suspect that practically all of that is glucose, rather than sucrose. The exact composition may vary more with storage duration and conditions than with variety. Why do you want a list?

"When I work that out on paper, I get 2 products," Me too. But I bet they are not interested in acetone.

Nitrous oxide is noted for being rather inert.

I'm not sure the question is really clear enough to answer. The question doesn't just ask about the reaction of ions with water; it asks specifically about the reaction of oxygen atoms with water. (atomic oxygen + water molecule = hydrogen peroxide? ) Under equilibrium conditions at NTP, oxygen atoms don't exist so I don't think the eqm position of the reaction matters. If you got a stream of oxygen put it through an arc or zapped it with hard UV and thereby generated some atoms then passed the gas mixture rapidly into water so that not all the atoms recombined before they got to the water then I'm ready to bet that some H2O2 would be formed.

Do you think those muscles don't metabolise stuff?

I think Degbahun is new to the forum and needs to find the "start new topic" button.

A really neat one is diffusion through a membrane of a silver/ palladium alloy. Why do you want to know?

I'm not sure the egg will crack at any reasonable pressure. I think it will squash slightly. Initially the egg will compress roughly evenly in all directions and the airspace in it will get smaller. Eventually the airspace will be crushed to nothing or dissolved. You can generally stretch ceramics (and eggshell looks a bit like a ceramic to me) by a % or so before it cracks, but they are relatively weak in tension because they have cracks that open up and become fractures. In compression they should be much stronger. With a 1% change in linear dimensions it would shrink by 3% by volume and I think that's about the size of the air space ( which is rather variable anyway). I think the shell can elastically deform enough to shrink the airspace to zero. Anyway, back to our squashed egg. It's now a thin layer of ceramic with hight pressure stuff on the outside and also on the inside. In the same way that my chest is able to support the massive forces on it due to air pressure, because it also has air in it at much the same pressure, I think the eggshell is now unlikely to break.

Fever is a "deliberate" act by the body. The idea is essentially to cook the bugs that are causing an infection. The body increases the metabolic rate; more fuel (i.e. food or body fat) is consumed and the temperature goes up.

Having a warning system isn't the whole story. http://xkcd.com/723/

You can, and I did. About a year ago in this very thread..

"was going to suggest carrying a glass bottle with a glass stopper of hydro-flouric acid " Once you learn how to spell hydrofluoric acid you can look it up and find out what it does to glass. That makes it an even better joke

There's a fairly good chance your car would be buried under the debris, but don't worry. You won't need to consider the problem for very long in an airtight container.

As a plant, but not as a drink. If caffeine is so addictive, how come I guzzle cola all week at work and yet do without any caffeine at the weekends?

This is all very interesting, but I don't think it has been on topic for a while. I don't think anyone has mentioned class since I said "I don't think there's any difference between middle and lower class in terms of the effect of the removal of collective bargaining."
