Have you read God Created the Integers? I own it but haven't read it since the maths is currently (or maybe perpetually) beyond me at the moment. I was wondering if it was one day worth attempting (I really dislike starting books and not finishing them).I actually picked this up at the swap meet a couple weeks ago and cannot recommend it. There are NUMEROUS typos, and, in the extended quote from the Principia they fail to include all the geometric diagrams that are in the original. As Newton tries to lead you through complicated geometric reasoning you have no diagrams to refer to.
It's an attractive coffee table book that, apparently, wasn't meant to actually be read.
I bought The emperor of all maladies: The biography of Cancer recently and it looks pretty awesome.
