Stat Mech Notes?

[emptymalei]

Thank you for this great repo. I noticed that there is no statistical mechanics. Is there a plan for it?

Hi @emptymalei --- it's on my todo list, I have some notes written up on in my notebook, but I need to convert it to .rst. Would you like to collaborate on that?

Can anyone help out? im not strong in stat phy, but i can type :)

I'll try to start writing it up and you can then review it and provide suggestions. Statistical mechanics is quite difficult, so despite taking many courses, I wasn't sure how to best write it up in some concise manner, without duplicating thick books about it. But I have some ideas now. I'll keep you guys posted. Thanks for the interest!

@certik I am writing down my lecture notes on github but I would like to read your notes and learn. And sure I can type too. :)

@emptymalei --- very nice notes! Maybe you can help me with the CSS styles to make theoretical-physics.net look more cool. Let me try to put my notes up in the next few days and I'll post a link to this issue so that you can have a look and we can try to improve it together.

[emptymalei]

@certik Thanks. I can do styling things but maybe after my exam in next week. Looking forward to your notes. 👍

[certik]

@emptymalei, I've finally started to write up my notes for thermodynamics and statistical mechanics, see #70. I'll probably merge it soon, so that you can see it online, and then we can improve upon it.

[emptymalei]

@certik wow cool. I would love to read it.

[certik]

Here you go: http://www.theoretical-physics.net/dev/statmech/main.html

It should be all correct, except this part here where I have a factor of 2 mistake in the derivation, which I'll fix tonight (update: fixed in 22ac70f).

Let me know what you think and which other things you would like to have there. This is just the beginning.

[emptymalei]

@certik Just read through it. It's very different from the approach that I was educated. I'll read it again carefully to learn more about your approach. For the first time, I know that Legendre transform could give us eight different function (2^3 for three variables?) here. Thx.

My observations at this stage:

1. Some equal sign problem in some of the equations,
2. more about Legendre transform in math section (?)

I made a diagram which explains the relations between the thermodynamics potentials, not sure if it's gonna help.

@emptymalei thanks for the feedback. This should be a standard approach, I am not inventing anything here, just summarizing the standard procedures, in a systematic way. Yes, I need to put there more explanations. Right now I am concentrating on making sure that all equations are correct. They should be now.

As to the Legendre transform, it's 1 initial function U, 3 functions with one variable transformed, 3 functions with two variable transformed and 1 function with three variable transformed, total of 1+3+3+1=8. If we had 4 variables, it would be 1 + 4 + 6 + 4 + 1 = 16 functions. So you might be right that it is 2^n options for n variables.
