Ken Robinson! He is awesome :) I saw this talk back in 2010 sometime (back when most Ted talks were actually good) I really really like him. He is such a good speaker and funny too. It's a shame he only did a few talks. I love his ideas on education. I haven't seen his latest talk though: "How to escape education's death valley" but I think I will have to watch it now. :) You can find his other talks too on TEDs website.
