T.E.D. - Ideas Worth Spreading

I've watched a bunch of these videos of lectures recently and have about 30 that I'm intending to post in the video section. Some of them are great! They're each about 20 minutes so they fit into a busy schedule pretty easily. To start I'd recommend Jane Goodall's "What separates us from the apes?" and Richard Dawkins' "An atheist's call to arms".
