Back to College, for free
I'm late to post today, but I have a good excuse. Lecturefox.com has a series of links to lectures in video, audio or text format from leading universities.
Lecturefox is a free service. You can find high-quality classes from universities all over the world. We collect without exception lectures from official universities, and we have a special interest in lectures from the faculties computer science, mathematics and physics. In the category faculty-mix you can find miscellaneous lectures from other departments like electrical engineering, chemistry, biology, psychology, economics, history and philosophy.
I have to admit it's a bit light on the economics so far, but for narrow-minded economists there are some great stuff on maths & stats, psychology and social trends to feed the mind.
If you are aware of similar resources, I would be grateful if you could post a comment or email me.
