THERMODYNAMICS AND STATISTICAL MECHANICS
INTRODUCTION: THERMODYNAMICS AND STATISTICAL MECHANICS OF THE PERFECT GAS
Ludwig Boltzmann, who spent much of his life studying statistical mechanics, died in 1906, by his own hand. Paul Ehrenfest, carrying on the work, died similarly in 1933, Now is our turn to study statistical mechanics.
Perhaps it will be wise to approach the subject cautiously. We will begin by considering the simplest meaningful example, the perfect gas, in order to get the central concepts sorted out, In Chap. 2 we will return to complete the solution of that problem, and the results will provide the foundation of much of the rest of the book,
The quantum mechanical solution for the energy levels of a particle in
(with periodic boundary conditions) is

    • As someone who graduated with a mechanical engineering degree where thermodynamics and its following classes was a large portion of my courses. I can say I’ve gotten close a few times.

    • My proffessor, 1st Quantitative Reasoning class: Nobody should have to take this class. The math is ugly, the class is hard, I been telling the uni this for 20 years 'nobody should be forced to take this class', even tho Id be out of a job, but they dont listen. This class sucks.
