From Edge:
Since the mid-1960s John Brockman has been at the cutting edge of ideas. He is a passionate advocate of both science and the arts, and his website Edge is a salon for the world's finest minds
The first thing you notice about Brockman, though, is the interesting way he bridges CP Snow's "Two Cultures" – the parallel universes of the arts and the sciences. When profilers ask him for pictures, one he often sends shows him with Andy Warhol and Bob Dylan, no less. Or shots of the billboard photographs of his head that were used to publicise an eminently forgettable 1968 movie, . But he's also one of the few people around who can phone Nobel laureates in science with a good chance that they will take the call. [Download Guardian Digital pdf of print edition]
