Gravity of Math

One of my majors in college was math, and I took a lot of extra math courses on top of what was required for the degree, so this book is right up my alley. If you're not into math, you might not find this book as interesting. Although the authors do a good job of keeping the descriptions at a level where a lay person can at least follow along, if not completely understand the concepts at hand. It's kind of a history of mathematics over the last 100 years or so, as told by physicists. And the accounts of Einstein struggling with the math were fascinating - especially if you have always assumed that he was a genius at everything. (Spoiler alert: he wasn't.)
