Higher Education: Video & Audio

TED is a nonprofit devoted to spreading ideas, usually in the form of short, powerful talks (18 minutes or less). TED began in 1984 as a conference where Technology, Entertainment and Design converged, and today covers almost all topics — from science to business to education — in more than 100 languages.

With a computer and an internet connection, you can now access free classes online from some of the very best colleges and universities around the world, as well as free lectures. A growing number of schools are making video and audio materials available.
