Einstein speaks

Yesterday I gave a talk at a Fermilab symposium celebrating the World Year of Physics. It was a great event, aimed mostly at local high-school students and the public more generally, although personally I learned alot from the other talks myself. My own talk was an overview of special and general relativity; you can see the slides here (warning: large pdf file). Eventually I think all the talks will be in video on the symposium web page. I played an audio file featuring Einstein himself explaining the basics of that equation E = mc^2 that we were talking about a while back. People were asking me where I stole it from, so here's the answer: an Einstein exhibit at the American Institute of Physics website. Give it a click; it's nice to hear the master himself talk about his formula, thick German accent and all.
