A book I read, enjoyed for the most part (except for the math), and thoroughly disagreed with the central idea was
Our Mathematical Universe by Max Tegmark. But as strange as is that idea that "all structures that exist mathematically exist also physically" and that any structures complex enough to contain self-aware substructures will subjectively perceive themselves as existing in a physically real world, I would hardly call him a peddler of "woo". I'd say he's simply another scientist who has a fascinating Theory Of Everything into which I have not been sold. Besides, the rest of his book is very mainstream, even if his main thesis is a throwback, in my opinion, to Pythagoras.
