Leonard Susskind, a Stanford physicist who helped conceptualize string theory and has waged a long-running “Black Hole War” with Stephen Hawking (see his newish book on that subject) offers a course on Cosmology, which studies the origin and development of the universe. It's actually the fifth course in a larger six-course introduction to Modern Physics (find them in our collection of Free University Courses). But the course stands on its own, and, along the way, it takes a close look at the Big Bang, the geometry of space-time, inflationary cosmology, dark matter, dark energy, the string theory landscape and more. You can access the full course on YouTube here, and also on iTunes here. Finally, the course comes out of Stanford's Continuing Studies program, which brings engaging classes to the broader public. If you happen to live in the San Francisco Bay Area (0r want to take top-notch writing courses online), give the program a look.
