Is the title of a new Three Part documentary by Martin Rees:http://www.channel4.com/science/microsites/W/what_we_still_dont_know/index.html If anyone gets to see this outside the UK, there is an interesting angle on 'perceptions and awareness'..or self-awareness. If one looks really closely, there is an interview with Lynn Rothschild, she is sitting on a chair in an academic courtyard, watch really careful as something weird happens! Just to the left of Lynn (if one goes to the link you can see her sitting down) there are some arches, in one part of the interview a person riding a bike appears, nothing strange exept the rider is pedalling and travelling backwards! I take it that the programme editor was instructed to insert this rider for a specific reason?..i hope to get a chance to see a repeat airing of this first show, and hopefully get a chance to record the series, which has some really thought provoking concepts, amazing documentary. P.S. if anyone in the UK has recorded the first programme, can you let me know what Lynn Rothschild was actually talking about at the moment the biker appears?
