This course aims to distinguish the basic methods of statistical physics and their application to some systems such as ideal gas, to distinguish between macroscopic states and microscopic states of physical systems, to study statistical calculations of quantities in thermodynamics and their application in quantitative statistical mechanics and the study of classical statistics represented by the Maxwell Boltzmann statistics, the study of velocities and their types in the Maxwell Boltzmann statistics, and the quantum mechanics of statistics, represented by the Fermi-Dirac statistics and the Bose Einstein statistics
