You may not have the time and money to go to University lectures. But there are other open options that the Internet is now offering. Many universities and famous institutions provide free online lectures. Let’s browse a few of the best ones I could find:
- Collège de France : the most famous French scientific institution has free-access lectures all year long. Most of them are available online too (from Mathematics to Philosophy through Archeology).
- The MIT publishes a number of lectures in video-on-demand (and has a large web site named OpenCourseWare).
- OpenYale is presenting seven free introductory courses taught by distinguished teachers and scholars at Yale University.
- Courses of all levels from the Washington University (introductory, undergraduate, graduate).
- PodCasts from UC San Diego
- Lectures from Vanderbilt.
- Computer and Computer Graphics, from University of British Columbia or from Virginia U.
- Webcasts from Oxford Internet Institute.
- Webcasts from Rice University.
- Podcasts from York College (NYC).
- Harvard at Home.
I could also advise you to check the Lecturefox Blog with a lot of information about these free lectures.
