TED stands for Technology, Entertainment, and Design. It started out as a yearly conference back in 1984. It is a place for thinkers to get together, some of which are selected to give up to a 18 minute speech. You had to actually attend the conference before, but now you can watch the shows on ted.com

 Here are some speechs that I have watched that I think are worth watching:

Burt Rutan: Entrepreneurs are the future of space flight (video)

Nicholas Negroponte: The vision behind One Laptop Per Child (video)

Bill Clinton: TED Prize wish: Let’s build a health care system in Rwanda (video)

Ben Saunders: Three things to know before you ski to the North Pole (video)
