PH-203 Statistical Physics
The aim of this module is to derive thermodynamics from the fundamental laws of microscopic physics and to introduce the student to the fundamental aspects of classical and quantum statistical physics. Maxwell-Boltzmann, Fermi-Dirac and Bose-Einstein statistics will be discussed.
