The Book of Numbers seems to be doing extremely well around the world. Cassell Illustrated just informed me that it's been sold to all these countries:

German - Primus

Dutch - Fontaine Uitgevers

Spanish - Editorial Paidos

French - Eyrolles

French Canadian - Reader's Digest

Japanese - Yu-Shokan

Korean - SKK University

Brazilian Portuguese - Larousse

Turkish - Domingo

So far I've only seen the UK, US and German versions so hopefully they'll mail some of these to me soon!

I saw this same mistake as well, and I believe the author had in mind altogether another problem Fermat had solved involving rational and irrational numbers.

Page 71 You state that for the Pythagorean theorem of squares, Fermat had proven that if the values of a and b were rational numbers then c had to be irrational. But for right angled triangle sides 3 and 4 the hypotenuse is 5. 5 is not an irrational number. I have been attempting to find Fermat's proof for the case where n =2 and c had to be irrational but can not find it. Can you assist?
