Skimmed through the more technical stuff. This is something I'd want to own, not just borrow from the library (which is what I did) so that I could look through it at my leisure, or when I needed to look something up. Really interesting. Learned some new anecdotes. Began to understand that mathematicians are even crazier than I had assumed.
An exquisite book containing many interesting concepts and factoids. The equations presented for the most part require a secure understanding of calculus. Beyond the explicit mathematics, Hawking briefly describes the life of about a dozen mathematicians before diving into their accomplishments and discoveries. Expensive for a book mostly containing material obtainable online for free, but still a solid read.
I liked the stories of the mathematicians, but all their papers were too long or confusing. The only one that I made it through was Turing's, which was fascinating.
I was lost by page 3. Then I scanned the rest of the book. I had hoped Hawking would explain some of these books in a more understandable way. Nope.
None of these types seem to believe in diagrams. It's all verbal descriptions which, if there is any ambiguity in the writing (which there was: Hawking needed a better editor), made it difficult/impossible to follow the mathematical descriptions and formulas.
