surely you'll wear a suit Mr Feynman

CERN have started digitising their tape library. By chance, I came across Feynman's talk immediately after a certain visit to Stockholm (free download as mp3 or ogg), which he mentions in Surely You are Joking...

Anyone interested in Feynman (hello narahttbbs!), should enjoy this. Perhaps the physics gets a little heavy at times, but much of it should be comprehensible to the non-scientist.

Cool optical illusion. Thanks to cleanskies for the link.
