Not too long ago I posted on the subject of the TED Talks - a lecture series given by some of the the most eloqent speakers in the world on subjects as diverse as education, economics, engineering and ecology. These short videos are for me a great example of the very best of the free, wide ranging teaching available out on the web.
The good news is that they are back. TED 2007 took place in early March so the videos are starting to appear, beginning with the winners of this year's awards: Bill Clinton, E O Wilson and James Nachtwey. And they are available in a hi-res 480p format.
