Cosmology (Winter 2009, Stanford Univ.). Instructor: Professor Leonard Susskind. This course of the Theoretical Minimum series will concentrate on cosmology, the science of the origin and development of the universe. Along the way, students will take a close look at the Big Bang, the geometry of space-time, inflationary cosmology, cosmic microwave background, dark matter, dark energy, the anthropic principle, and the string theory landscape.
