The pre-requisite for this course is PHY 303 (Thermal Physics). The course begins with the microscopic basics for thermodynamics; that is, explaining large system properties from properties of individual particles in order to formulate the important fundamental concepts: entropy from Boltzmann formula, partition etc. through the presentation of quantum statistics, Bose statistics and Fermi-Dirac statistics are established, including the special classical situation of Maxwell-Boltzmann statistics.
