Science & Mathematics - 20 December 2007

I remember the comment in Event Horizon (that really scary movie O.o) That fire in 0G acts like a fluid and Laurence Fishburne described it to be really freakin' trippy.

Anyone know what it looks like? Video Link/ pic's would be nice :)

bats use ultrasound, which we also use to see inside our bodies. No doubt the frequencies are different. But to a bat, some things are presumably transparent that wouldn't be to us light-obsessed creatures.

What can they see through?

and is there a danger of them crashing into it?

My Calc Assg. over break is to come back to school in January and be able to speak intelligently on "Fermat's Little Theorem," and there could be a quiz that's going to make us prove it. No one in my class has ever heard of this before, and it's not in the book.
I found a ton of stuff on it online, but it makes no sense and its really weird. How should I learn this??

How is it possible to 'waste' water? Like, when they say don't let the faucet run because you're wasting water...doesn't it just go back into the earth anyway? I thought it was cleaned at a water-treament center, then like, recycled...how is that wasting? I don't get it....
