Curved space-time, dark matter, dark energy, the big bang, what’s it all about? Join us in our quest to understand and explain the beginnings, the evolution, and the nature of our universe. This study group, which is part of a multi-year continuing series, is intended to build a broad and comprehensive theoretical minimum knowledge of modern physics for non-physicists and science groupies. We began our study of cosmology in the 2017–18 winter session, and will conclude the topic in the spring semester. This study group will utilize mathematics to develop the theory and to explain and apply the principles. Our studies will be based on an online video lecture series “The Theoretical Minimum — Cosmology,” originally given by world renowned physicist Leonard Susskind, Director of the Stanford Institute for Theoretical Physics (SITP), in Stanford’s Continuing Education Program. We welcome all members with a curiosity and interest in understanding the nature and history of the universe. General familiarity with principles of classical physics and calculus is required. Internet access is essential.
