Solutions to Problem Set 6
This week is all about looking at the behavior of model systems. Our goal is to calculate
approximate entropy functions to see how they behave.
1. Schroeder Problem 2.42. Black holes!
Before we start on th

1. Schroeder Problem 3.34. Rubber bands and Universality.
This problem is marvelous: It gives you a chance to see how the underlying physics of
very different systems can look essentially identical

Solutions to Problem Set 12
Bose gases! No Pauli Exclusion Principle here, but a certain amount of confusion arises
over the chemical potential because many bosons carry mass and many do not. Photons
are massless bosons and there is
