TED Talks

TED began in 1984 as a conference where Technology, Entertainment and Design converged, and today it puts on two conferences yearly that cover almost all topics, with speakers who are the leaders in their field giving a presentation that lasts no more than 18 minutes. We post a new TED Talk almost every day. (NOTE: The videos in this category are all free to non-members, as a demonstration of how our video playback system works.)

  • Dare to refuse the origin myths that claim who you are | Chetan Bhatt
