Thermodynamics of metals like insulators which handle high heats . This lecture is informative intro to it . Thanks MIT.

[@andreandes7485]

This is my dream course to take. I’ll be back in about a year after I do all the prerequisites

[@joro8604]

Great explanation.

[@christophergame7977]

Putting the cart before the horse. Talking about molecules and statistical mechanics when the announced topic is thermodynamics.

[@RagHelen]

When he says around 9:00 that is unlikely for the air in the room to be suddenly gathered in one corner: You would need to invest energy and work to accomplish that by intention. But the probability he is talking about is ground in parts per space.

[@kushagra64]

3:59 now that's funny XD

[@anggalol]

Please do more math courses

[@burnere633]

Is this actually from 2021?
1. Video quality doesn't shout 2021.
2. What were students doing *inside* a classroom in 2021, all sitting so close to each other?

[@Ommygee007]

Please we need med class lectures.....apart from that woman🙏🙏🙏🙏
Please get it for me

[@coincrazy3563]

should

[@lonnybulldozer8426]

Nice j accent. He is a j man.

[@hugodaniel8975]

Wish mit had more diverse set of professors

[@n3sstxi]

half of em can barely speak english

[@joro8604]

Why?

[@ifrazali3052]

Wdym?

[@lonnybulldozer8426]

I hear you, and agree. 99% of them are j's.
