He is the co-founder of string theory, or m-theory. He has had a lot of appearances on TV and he also has a few books. I just bought his newest book "Parallel Worlds" not too long ago but haven't started it yet because I'm finishing up Ray Kurzweil's "The Singularity is Near". Is anyone else familiar with Dr. Kaku?
