Oh, about "Our Mathematical Universe"...

GREAT book. But I have to echo Mario Livio's criticism of the idea that all mathematical possiblities are real, a la Tegmark. We have to assume principle of mediocrity on our own universe--that we aren't that unique. Now, if every mathematical possibility is real, than most universes would be much more complicated than ours--follow many more mathematical rules, have a much larger number of dimensions, etc. Our world is much simpler than it could be---so unless we're at the far end of the Bell Curve (and the fact that life only can exist with three spatial dimensions and one time dimension MIGHT be a limiting factor) we have to assume his assumptions are wrong. See Livio's IS GOD A MATHEMATICIAN?

Cannot recommend enough. I am about to steal shamelessly from it, with a little extra added.

I never claimed most of my ideas were original. Indeed, varients of them have been circulating for decades, although for some reason they've never been penatraed into the mainstream general consciousness. I'm just one of the first to present them in illustrated, comic form.

Ellis is a wonderfully clear thinker, and has co-written with Hawking, as well as contributing numerous articles to SCIENCE and other scientific journals. I respect a lot of thinkers. I cannot think of one I respect more.

NEXT: Take a Chance.
