This series of lectures is amazing. When I studied thermodynamics as an undergraduate engineering student I never encountered such clear explanations and derivations of this fascinating subject. Thanks a million!

It may be very useful to describe each video content with the time at which the content start in each video. It is difficult to move back and forth and locate the start of each part.

00:00 : Calculation of pressure at fixed entropy, as a function of free energy at fixed temperature

13:34 Adiabatic theorem

48:50 : Ideal Gas

Mr Susskind is an awersome teacher and aslo is a top scientist. That is very very unusual according with my experience. These videos are invaluable!.

Good, I like that you share this video, I wish success always explores the formulas some of applications of Helm-Holtz free energy, and discusses the importance of the partition function.

@PLecN yeah I'd figure the partition function has limits

@unusedName1 Professor Susskind does an excellent JOJ of explaining physics, statistical mechanics, string theory, quantum theory, general relativity and particle particles. Pardon my usage of "meme" language "JOJ" means job, he is one the best teachers around universities, his passion for his JOJ and good sense of humour, and well as a superb understanding of the history of physics, and mathematical physics

Is that beer on his table?

[lovelplants]

hehe he's not recording what he did last time lol... but i like this teacher tho.. he have a lot of interesting view about physics.. lol..

[agapitoflores001]

He teaches the lesson well. I like this professor..

[PLecN]

@PLecN Hmm think I've answered this myself ... the integral over positions is not from -inf to inf, but just over the volume. It's the integration over momenta that can be taken to go from -inf to inf.
