StumbleUpon does have it's advantages

I found this today and thought i'd mention it here. Unsure if it's been previously mentioned.

Open Yale Courses provides free and open access to a selection of introductory courses taught by distinguished teachers and scholars at Yale University. The aim of the project is to expand access to educational materials for all who wish to learn.

-All lectures were recorded in the Yale College classroom and are available in video, audio, and text transcript formats
-Registration is not required
-No course credit, degree, or certificate is available
I think this is helpful if you are interested in a subject but not quite sure if to pursue it just yet.

I've downloaded Psychology, Philosophy and Physics material.

Happy learning people
