Went to a very interesting lecture by Dr Mark Lewney on guitar and string theory. Catch it if you can.
http://www.hpl.hp.com/news/lectures/...ts/lewney.html...Dr Lewney will then show how the vibrations of guitar strings might be applied to the particles we're all made of, but with a twist: the strings vibrate in extra dimensions. Charming stories and mind-bending animations are used to try to get the audience to think in 4, 5 or even 11D. This introduction to Superstring Theory shares the wonder and excitement of such grand scale, cutting edge physics.
