Some fifteen years John Brockman, a restless promoter of culture, an intellectual entrepreneur, organizes a strange Christmas party. Brockman, who said that it is one of the great intellectual enzymes of our time, does not meet his family for dinner Turkey or opening gifts from Santaclos. It invites some of the brightest minds in the world to virtually meet at edge.org, your Internet homepage, to answer a provocative question. The party is the conversation that is woven from the responses. The annual celebration of edge is a bridge between two cultures that are ignored. Arts and Sciences sharing the delicacy of a good question. Among his regular guests can be found to Steven Pinker, Richard Dawkins, Craig Venter, Brian Eno, Daniel Dennet, Samuel Harris. Yes, little diversity. Many English men or Americans — but, in the end, a group with things to say.
