Wow! Talk about one awesome PBS special. I just got done watching it and it was simply amazing. For those who don't know, The Elegant Universe is a new PBS special that acts as kind of an 'Idiot's Guide to Theoretical Physics' and is narrorated by Brian Greene, a professor of Physics at Colombia University. NOVA, the organization behind many, many science based films, created this masterpiece. The show, I believe, is based on a book of the same title written by Mr. Greene. Here is the PBS link for the Elegant Universe.
