During the eighteenth and nineteenth centuries there was a renaissance in understanding how the familiar world around us works. We now call that “Classical Mechanics,” referring to physics as it was understood before the advent of quantum mechanics. It incorporates a set of principles and rules that governs all physical phenomena for which quantum uncertainty is not important and provides the foundation for theories of the quantum world. This study group will explore the theories and principles of Classical Mechanics. Unlike other popularizations of physics that shy away, this group utilizes mathematics to develop the theories and to explain and apply the principles. Our studies are based on an online video lecture series Classical Mechanics, originally given by world renowned physicist Leonard Susskind. We will also utilize a book, The Theoretical Minimum by Leonard Susskind and George Hrabovsky (Basic Books, 2013), which is based on the video lecture series. 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 this intellectually challenging peer learning experience.
