In this video we give a complete introduction to the foundations of statistical mechanics.
We are going to examine the physics of macroscopic systems. It is the physics used to describe systems with number of particles on the order of 10^23, the Avogadro constant.

With such numerous degrees of freedom, keeping track of the motion of each individual particle becomes untenable, one is therefore forced to combine the use of the laws of mechanics with statistics, to describe the averages and aggregates of physical observables.

And so statistical mechanics was born. At the heart of this subject lies the partition function, which carries all information concerning a macroscopic system in thermal equilibrium. This is today’s topic.

Excellent high-level review of a semesters class in Statistical Physics.

[mohammedpatel]

Excellent derivations connecting micro to the macro

[anywallsocket]

Studying for my SM final now, this is very helpful 🙏

[ranjitchoudhury]

beautiful presentation. Quote from Marx attracted my curiosity. Very nice.

[mikep]

Great video. Can you recommend a book that deals with the topic in a similar way and at a similar level?

6:15 - What do you mean "the number of ways a system could be in the microstate psi i"? Isn't a given microstate unique? Can't it only be in a microstate in one way?

[iridium]

How do you compute the pressure gradient in a system with a long range force?

[gabitheancient]

why are people mad at quoting karl marx lol

[sirreginaldowls]

love the karl marx quote! don't listen to the losers

[jamesyeung]

by quoting marx you've become the most based physicist there is :)

[millamulisha]

Ironically Marx was notoriously bad at mathematics and didn't understand calculus...

[daffavirwandy]

It would be fine if karl marx a honourable or at least a scientist in this context, but this is something else...

Pretty decent covering of basics. You reached certain level of knowledge of the theory. Unless like in good theoretical physicists papers, experiments on the field of sociology and social engeneering, based on uthopic ideas of some desilusional mind lead to disaster. That is why Marx is conssidered bad boy in all countries that experienced his "ideologic influence". Maybe becouse unlike in physics he creates constructs based on assumptions based on assumptions etc. without any glimpse of experiment. And after all some crazy russian and many of his followers take all manylayered concept of nonsenses to put it in action. Lol.. I wish you all sympatizants to experience such a regime.. you may speak little less riddiculous afterwards.
