Kendra Rocks, she just gave me the Elegant Universe series on DVD. It is all about the theory of everything or string theory. It is pretty interesting although it WAY over my head because I can hardly add. Still some of the ideas that they talk about are pretty cool. You can watch the whole thing on line. And you should http://www.pbs.org/wgbh/nova/elegant/program.html because when they solve everything you can say "Yeah I knew all about that way back when..."
