This course covers topics of basic concepts and methods of statistical physics and their application to simple systems such as ideal gas, solids specific heat and blackbody radiation. Statistical physics, the development of mechanical thermology and mechanical statistics, the concept of heat, the laws of thermodynamics, the concept of chaos and free energy. And the application of the principles of statistical physics to selected physical systems and statistical distributions, which include both: the Maxwell - Boltzmann distribution, the Bose - Einstein distribution, and the Fermi - Dirac distribution with their applications and computational applications for each of the free energy, chaos and magnetism of conventional and quantitative systems.
