The 50 or so top-billed speakers at the annual [Technology, Entertainment and Design] conference are asked to hew to a strict set of rules: an 18-minute limit on presentations, no commercializing, and don't give the same spiel you've been delivering for years. It works pretty well and explains why some of the brightest physicists, artists, ocean explorers, linguists, tech wizards, historians, architects and futurists ... have been flocking to Monterey, Calif. The current curator," Chris Anderson ... sees a mission for the event. He believes that the TED "community" can make a big social impact; the conference now reflects that idea. By now it's fair to say that the [concern] about global warming, human rights violations, the state of Africa, and other woes are part of TED's character. The activist goals culminate in three annual TED Prize awards, which involve committed people being granted a "wish"-along with $100,000 cash to improve the world in some way, whereupon TED-sters are welcomed to help make it happen. (Outsiders can help too; go to tedprize.org if you're interested.) This year's honorees included hip novelist Dave Eggers, who helps organize neighborhood tutoring centers and wants to get people involved in helping public schools; physicist Neil Turok, a founder of a mathematics institute in Africa who wants the next Einstein to come from that continent; and ... Karen Armstrong, whose goal is to gather "spiritual leaders and thinkers" to write a "Charter for Compassion" based on the traditions of Christianity, Judaism, and Islam.
