1) I saw most of the movie 'The Last Castle'. What I saw was pretty good. Because the power went out, I missed the last part. I was at the part where the trebuchet attacks the Colonel, and the power went out. Stupid trees. Anyway, does anyone know where I can get a copy of this to download? 2) I was thinking about this in science class. Heat goes away by dispersing to other matter. But heat is often created. I thought, wouldn't everything get hotter? So then I thought, well that energy transfers to other forms of energy. Then I got kinda confused. I'm guessing most energy is in kind of a neverending cycle through various stages, because of the Law of Conservation of Energy.

Sorry about the movie. Ending is great. I won't give it away, but he shows his leadership ability well. Anyway, you are correct. The law of conservation of energy says that energy, no matter in what reaction or movement, can neither be created nor destroyed. The flow of energy is a neverending 100% efficient cycle.

I've heard the ending is great. Don't anyone give it away! I love how they set up defenses with the wall... Also, I believe the Law says 'can neither be created nor destroyed by ordinary means.'

On question 2, ask your teacher about entropy and the Second Law of Thermodynamics. I couldn't find a decent link to a web site, except for college notes and philosophy discussions.

Heat doesn't "go away". Heat is transfered by one or more of the following: conduction, convection, or radiation.

That's what I meant - it transfers to something else. AeroE - she wouldn't know. She's a very dumb blonde. What is everyone else's opinion on the movie? Please don't give away the end.

The universe will eventually end in a big, same-temperature soup. You can collect more heat in one place, but it takes energy to do that. What happens if you stick a refrigerator with the door open in a perfectly insulated room and supply power to it? The room will wind up getting hotter.
