I just heard about this tonight and thought I would share it. There are lots of universities that have online courses but this is a new website that has a collaborative agreement with some of the top universities in the country like Stanford, Princeton, and Penn. They are offering FREE online classes. These are not watered down versions but the actual courses they give to students who are attending the school ( and paying upwards of $55,000/year). You don’t get course credit currently, just a certificate of completion but more importantly you learn from some of the best teachers in the world on a whole range of interesting subjects.
Anyway for anyone who might be interested here’s the link… https://www.coursera.org/
