Mandl, Statistical Physics, Wiley. This is fairly advanced, but it's always worthwhile to see what Feynman has to say. Callen, Thermodynamics, Wiley. A classic treatment of thermodynamics. I've asked that all the above be placed on reserve at Fine Library. Homework: Assigned Monday I will try, but sometimes the assignment may not be ready until Wednesday!

Collaboration encouraged but not copying! Late homework may receive only half or none of the grade depending on how late it is and how it fits into the grading schedule!

We will cover the Boltzmann, Bose, and Fermi distributions; black body radiation; chemical potential; Gibbs free energy; and phase transitions. A more detailed syllabus is in the table below. Note that I write the lecture notes mainly so I know what I'm going to say.

I like to distribute them so you can follow along in lecture rather than having to worry about taking notes. You will need a to be able to view and print PDF for downloading to be useful! The files are large because the fonts used by TeX are embedded in the files.

If you discover errors or typos, or just plain unclear passages, let me know at groth physics. You may occasionally get a file not found error if I've put in the link, but haven't installed to the actual file yet.
