As founder, editor, and publisher of the intellectual forum www.edge.org, John Brockman is well-positioned to initiate and cultivate an ongoing dialogue with today’s leading cutting-edge thinkers.  The website is a virtual salon for every type of intellectual and scientific pursuit, from evolutionary biology and quantum physics, to crowd psychology and miniaturized computing.  Through this vibrant and varied online community, Brockman has shifted sharply away from the stereotype of the introverted, out-of-touch scientist and introduced the reality of a fully aware and involved scientific society.Science at the Edge reflects this brave new world, and Brockman has assembled some of the today’s most revolutionary scholars from all scientific disciplines to discuss their unique contributions to the development of modern thought.
