Chapter 15: Statistical Mechanics


Statistical mechanics is the study of systems with large numbers of particles and serves to connect microscopic properties of individual particles to macroscopically observable quantities.  This chapter limits its focus of statistical mechanics to a comparison between the classical and quantum statistics and some of the associated applications.  Quantum statistics operates when particles are indistinguishable and the type of statistics depends on the spin of the particles: Bose-Einstein statistics for bosons (integer or zero spin particles) and Fermi-Dirac statistics for fermions (half-integer spin particles).
