Statistical mechanics is a branch of physics that applies probability theory to the study of the thermodynamic behavior of systems. It provides a framework for relating the microscopic properties of atoms and molecules to the macroscopic properties of materials that can be observed in everyday life. The focus of this group will be to understand how thermodynamics and magnetism can be explained by applying classical and quantum principles of mechanics and statistics at the atomic level. Unlike other popularizations that shy away, this group utilizes mathematics to develop the theories and to explain and apply the principles of physics. Our studies will utilize an online video lecture series "Statistical Mechanics," originally given by world renowned physicist Leonard Susskind, Director of the Stanford Institute for Theoretical Physics (SITP), in Stanford’s Continuing Studies Program. The study group is intended to build a broad and comprehensive minimum theoretical knowledge of physics for non-physicists and serious science groupies. A familiarity with college-level calculus is recommended; internet access is essential. This group welcomes all members, regardless of background, who are prepared to actively participate in a unique, intellectually challenging peer learning experience. There will be no meeting on the Wednesday before Thanksgiving.
