Everyone says "there's no such thing as a free lunch" these days, but faculty at the Massachusetts Institute of Technology disagree. Although there may be no food involved in this free offer, MIT began publishing its courses online for the general public to view for free about five years ago -- and the program just keeps growing!

Self-learners around the world can now log in at http://ocw.mit.edu/index.html to view their 1,700-plus class offerings, which include online syllabi, suggested readings, lecture notes, problem sets, etc. So, if you've ever dreamed of attending a world-class educational institution, it's certainly worth a look!
