After the success of last year’s question to leading scientists, “What do you believe is true even though you cannot prove it?”, the Edge Foundation’s World Question Centre has now provoked a new round of thinking with the question for 2006: “What is your dangerous idea?” With answers from a diverse group of scientists and thinkers including Richard Dawkins, Brian Greene, Michael Shermer, Freeman Dyson and Clifford Pickover, you can be sure of some interesting reads. Shame the question wasn’t posed to a few of the really ‘dangerous’ scientists though, those on the edge like Stuart Hameroff (or at least his highly credentialled partner, Roger Penrose).
