Yale has put 7 free courses online–complete courses. You don’t need to enroll, but, then again, you can’t talk to the faculty, so there’s a trade-off. Still, this is a great idea and opportunity, and a good example of using technology to serve society.
Hmm. Since they are all introductory courses, and since I’ve taken many, many courses, I think I’m up for Physics, a subject I always wanted to know more about. I’ll let you know what I discover.
