Michio Kaku

I explored my nerdy side over the weekend and watched BookTV on C-SPAN2.  There is a three hour interview on line - the same one that was on BookTV that you can reach by clicking Michio Kaku above.  He is a physicist and a proponent of string theory.  I am not going to attempt an explanation here, but it is an attempt at a unifying theory of the universe.  If you can watch some of it, I encourage you to do so.
