Thermodynamics and Statistical Physics I,II,III (1399-1400)

This is a three-semester course on Thermodynamics and Statistical Mechanics which is supposed to be covered in the following order:

Semester I-Fall of 1399: Thermodynamics,

Semester II-Winter of 1399 and Spring of 1400: Statistical Mechanics,

Semester III-Fall of 1400: Advanced Statistical Mechanics.

The textbook for semester I: Thermodynamics

I mainly follow the following textbook:

Thermodynamics and an Introduction to Thermostatics, by Herbert Callen

Contrary to most other texts which are inspired by engineering (engines, refrigrators, etc), this book constructs Thermodynamic  on a rigorous physical and mathematical axiomatic sytem.

Grading system:

In the beginning of the course, you are supposed to choose your team (2 or 3 students). Each team is supposed to collaborate with each other on each of the problems, type the solutions with Latex  and deliver them in pdf format. There is no midterm or final exam and your final grade is based on your homework sets and your activity in the class i.e. genuine contribution in discussions.

Online Class Schedule:

Time:10:30 AM-12:00 AM Sunday and Tuesday


The first session is on Sunday 30th of Shahriv

Teaching Assistants:
