0:00.0	I'm going to make the walls of a material that is bad at conduction, bad at convection, and bad
0:08.7	at raising it. I got a heat prison. That's what I got.
0:14.0	I believe we have what we have here.
0:18.0	It's a failure to radiate. Star Talk, your place in the universe
0:33.0	where science and pop culture collide.
0:37.0	Star Talk begins right now.
0:40.8	The Chuck, yeah.
0:42.4	I'm gonna talk to you about heat transfer.
0:44.0	All right, did he put in for a transfer?
0:47.0	I cannot take these conditions any longer.
0:52.0	I have put it in for... take these conditions any longer.
0:57.0	I put it in for transfer right now. This is a hostile work environment.
1:00.0	All right, so basically, unless you pump energy into a system, a system left all by itself,
1:09.2	okay, energy will go from the thing that's hotter to the thing that's colder.
1:15.8	Right.
1:16.7	That is not some great revelation.
1:18.8	No, that is something that you learn
