Professor Susskind continues the discussion of phase transitions beginning with a review of the Ising model and then introduces the physics of the liquid-gas phase transition. Recorded on June 3, 2013.
Statistical mechanics is a branch of physics that applies probability theory to the study of the thermodynamic behavior of systems composed of a large number of particles. Statistical mechanics provides a framework for relating the microscopic properties of individual atoms and molecules to the macroscopic bulk properties of materials that can be observed in everyday life. Thus it explains thermodynamics as a result of the classical and quantum-mechanical descriptions of statistics and mechanics at the microscopic level.
