well Mise, Perfection, uppi are all write. Nonconformist, thats the defenition, by solution I meant what x is at a given value of t.
The answer I was actualy looking for was kcos(wt) + ksin(wt), but the answers above are identical. Mathematically speacking, uppi gave the most pure answer but I'll give it to mise as he answered it first.

Your up Mise
 
What does Baryon Asymmetry mean?

Baryon Assmetry is the fact that the practically all baryons (basically protons and neutrons) that we can observe in the universe are matter and not anti-matter, although during the hadronisation in the Big Bang the creation rates should be about equal. There isn't any conclusive explanation yet why either more matter than anti-matter was created or where all the anti-matter went.

One candidate for the explanation is CP-violation and one of the experiments at the LHC was built to search for such CP-violations in baryons.
 
Suppose you have a bunch of different metals in your lab and you want to order them by their heat conductivity around room temperature. Unfortunately for some reason you cannot measure it directly (maybe you thermometer is broken or something...). What other property of the metals that is not related to to heat can you measure to get a good estimate of the relative heat conductivities and why?
 
Electrical conductivity, because both use the free electrons in the metal?

Yes. The relation electrical/heat conductivity is pretty constant across most metals, because of the reason you mentioned.

Your turn
 
Personally I'd just touch them. The ones that felt coldest would be the better conductors.

Ah, but:

Anyway, this is a sort of 'history of science/scientists' question because I can't think of anything better:

Why did physicist Henry Cavendish, often credited with the discovery of hydrogen, have a back staircase added to his house?
 
He was afraid of fire.
He didn't want his maid waking him up.
He liked that song with the chorus "who's been sneakin' round my back stair?"
 
Speaking of maids a milking, someone tell me something special about the first batches of milk after a calf is born.
