This is a wonderful book. A word of caution though: don't get the Kindle version from Amazon. I thought I'd get it for the Kindle, because the print version is huge and I sometimes like to read in bed and don't want to lug the dead tree version I own around, but I had to return it because of the standard problems with garbled notation (some symbols appearing as a square box or some other incorrect symbol) that affects every math book I've ever purchased on Amazon for the Kindle.

There error rate was much lower than in any other math book I've tried, but still much too high.
