It was a very interesting talk - it reminded me of lots of stuff I had heard before, and only half understood.

Good luck with your book - when I was a child, I read George Gamow's Mr Tompkins (http://en.wikipedia.org/wiki/Mr_Tompkins) In Paperback (http://www.amazon.co.uk/Tompkins-Paperback-Canto-Roger-Penrose/dp/0521447712/ref=sr_1_1?ie=UTF8&s=books&qid=1207678177&sr=8-1), and it had a big effect on me - I hope you are able to inspire children in science, too!
