Incredible Numbers

Review Excerpt: This interactive book mixes clearly written middle and high school level reading with 71 interactive, embedded and finger-driven math demonstrations. As a result, this is a math book that you touch as well as read. The text comes from 23 articles written by Ian Stewart, a math professor. Those seeking a challenge can try to solve the 15 puzzles (with illustrated answers). The main menu presents eight large dots; each representing  color-coded chapters as follows: Primes, Secret Codes, Polygons, Infinity, pi, Factorials, Music and Nature.
