Leonard Susskind (famous string theory advocate at Stanford) teaches an interesting set of courses in physics in continuing education. I will be posting some of his lectures here.

Susskind is a great communicator, so well worth watching-especially for those interested in self-study of quantum mechanics, relativity and string theory.
