If you’ve not heard of Richard Feynman then you are very lucky. It means that you can have the experience of finding out all about him for the first time.
Richard Feynman was a Nobel Prize winning, safe cracking, bongo drum playing, beautiful women painting, atom bomb making genius. Go and read Surely You’re Joking Mr. Feynman! to discover more.
And now you can get to see the man in action delivering a set of lectures about physics that have been put in the internets by Microsoft at their Project Tuva site. This lets you view the presentations with annotations and additional linkable content. A great way to spend a lunch hour or two.
