The Thing

We don't usually try to solidify gases such as Nitrogen without increasing pressure. And helium is the only gas I know of that shows superfluidity near 0K. Any researchers there knows?

Depends on the chemicals you have. If you just want to do some lab procedures of, say, extracting not-very-dangerous gases, get a book from the library, since they are all over the places now. If you want to, say, extract fluorine, you'll need better stuff like platinum. So I'd say get a book.

Well, the most practical way is to cancel the zeros when you see them, but I don't recommend this as much, for, like doing sqr roots, 0s are very important. Sqr(1000) is not 10, so, yeah. There are lots of tricks to calculating large numbers, such as getting the square of 2 digiter with ones digit of 5 instantaneously and stuff like that. Go find a book in the library and usually they have assortments of tricks.

A water tunnel will work just like a wind tunnel if you want to test aerodynamics. If you wish to use a windtunnel, install a smoke system. In many pics you see about aerodynamics testing you see these really fine lines of smoke. No idea how they got that perfect smoke tho.

There are two drags. Induced and parasite. Both increase if you add wings, and even if the wings get the car into the air it will drop, unless the car glides, which slides off topic a bit. Don't think it will save a lot of gasoline.

Gee, they must have some kind of formula. You see it in computer programs, with sin functions. Even in programs like VB they have premade functions of sine in radians. Try asking a comp expert and he might know, although the idea seems absurd.

Helium, most stable of all elements. Have they even solidified Helium yet?

New to this forum obviously. Hey Im a lepton! Leptons pwn Neutrinos.

About 2 hours. I only hope that it is a bit more interesting than Return of the Jedi, which had like an hour of dancing at the beginning. It was the worst episode. I think this episode will include how Annikin became Darthvader. Can't wait for it.
