One to Nine: The Inner Life of Numbers

I am enjoying the book a lot, but bewarned--you may not get a lot of the references he makes if you don't a some math background. I have undergraduate degrees in math and physics and I needed that to understand some of the details. Hodges discusses a lot more than just the numbers. For example he uses the number eight (one byte) as an excuse to discuss a lot about computers and computing with many (interesting) references to the ideas of Alan Turing (about whom he wrote a book). Many of the other chapters also wander into areas you might not have guessed were related to that number--but that's not a bad thing. I recommend the book to readers who haven't forgotten all their algebra.
