This question is about chinese fast-food orange chicken (the deep-fried amorphous nuggets with a thick tangy glaze). When I take a deep smell from a hot bowl of this chicken, or hold it in my mouth and breathe around it, some sort of irritating vapor makes me cough (or stings my nose). Just one cough – enough to keep it from getting into my lungs. Once the chicken cools down (to mouth temperature, even) it doesn't happen. It reminds me of the reaction I've had sniffing acid in lab – could it be lots of volatile vinegar? I've experienced this with fast-food chicken in more than one college food court.

Is there an easy, inexpensive way to check if the meds I order from overseas by are real? For example, would the solution linked below be something a total novice could do? How could I actually learn the process?
(and please, no lectures on whether ordering from overseas is good idea. That's what I'm trying to find out.) thanks.

"A human is halfway in size between an atom and the known universe"... This is a paraphrased quote I have come across several times. I like it. Who said it first? How true is it in the most literal sense? And, finally, what errors arrive in postulating a universe, or an atom, which can be measured AT ALL from our singular, relativistic, perspective?

Last week at a friends house we were sitting around a nice fire, when my brother found one of those silica gel packets, and (stupidly) threw it in. The room almost immediately filled with noxious fumes, and our throats hurt for a couple days afterwards. What happened when that silica burned, and was any permanent damage done?

Here's one for all the chemistry majors out there. I'm going to be making an herbal tincture using Everclear as the solvent. After the tincture has been made, is it possible to get rid of the alcohol by heating the solution gently in a double boiler without affecting the potency of the tincture? [more inside]

What is the underlying physiological cause for paresthesia (tingling of the fingers) secondary to hyperventilation?
Specifically, what metabolic or neurological process causes you to feel tingling in your fingers when you hyperventilate?

My company develops chromatography software. It has recently developed several ways of automating certain processes that will help the user save time and automate things. I'm trying to think of a collective name for them. "Timekeeper Technology" is one I've just thought of. Can you think of any others?

Has anyone ever done a study on the neurological effects of the first week or two of a love relationship? There's got to be some sort of brain chemical released during that period... but what is it? Or, in broader terms: What's responsible for that heady, crazy, giggly feeling that both guys and girls get?

In America (and in Europe, too, I suppose), we use the Linnaean taxonomic system for living things and have certain specific terms (acetate, polymerase, cholinergic, etc.) that are used in chemistry, for example; how does such terminology work in other languages, especially those very dissimilar to English, such as Chinese?
