Is anyone else here a fan of 'The Edge', a website on which some well known scientists and academics write about their Big Ideas?
http://www.edge.org
The Telegraph ran a Christmas spread inspired by The Edge's 2005 question which asked scientists to complete the statement "I beliebe but cannot prove..."
The question for 2006 is "What is your Dangerous idea?"
(I'm not associated with the site in any way, just a reader who found herself thinking up all sorts of ideas for novels after an hour or two on the site.)
