Ideas worth spreading

Thanks to a post by John Hodgman, I was introduced yesterday to TED.com. TED (which stands for Technology, Entertainment, Design) is an organization that focuses on finding new, inspiring, cutting edge ideas in science, business, the arts and the global issues facing our world, as well as technology, entertainment and design and once found spreading those ideas freely as widely as possible. So there are many videos on this site, that are free for download. This is a great resource for educators.
