Review by goldenphoenix (2005-01-04)
I was instructed to read this book by my maths teacher,who was deeply impressed with it. I was reluctant, unwilling to take reading advice from a woman who's life is numbers, not words. I can see why she enjoyed it, it was one of those 'thinking' books, but the reason I enjoyed it so much was because of its lively character. It was witty and yet very sad, and the story was told in a totally original way.
I don't think I've ever read a book that can appeal to so many people in so many different ways. Mathematicians, people who've had experiences with ortism, and artists alike will enjoy this book equally.

This is an excellent book.
However, one chapter has annoyed me so much that I wanted to express it somewhere!
Chapter 19 explains how to find all the prime numbers. First he glosses over the fact that 1 is not a prime number. Second he states that you write out a list of numbers, then remove all the multiples of two, then all the multiples of 3 then 4, 5, 6 and so on. This is stupid and Christopher would not make this mistake. After the multiples of two have been eliminated there are no multiples of 4 or 6 left! In fact after eliminating all multiples of 2 and 3, the next number to be eliminated is 25 (5^2).
It is a shame no one picked up on this in the editing process.
Please do not let this put you off, the rest of the book is superb!
