This week's TED Talks features Professor Richard Baraniuk who explains the vision behind Connexions, his open-source, online education system.

Richard Baraniuk is founder of Connexions, a free, open-source, global clearinghouse of course materials. People in some 200 countries tap into its vast store of texts on everything from engineering to ornithology to music, adapting the content as they see fit.
