Is it a novel, a biography or a textbook? Toying with the boundaries of all
three, Apostolos Doxiadis鈥檚 entrancing Uncle Petros and Golbach鈥檚
Conjecture mixes real maths and mathematicians with a fictional professor
who wastes his life shuffling beans in an attempt to prove that every even
number is the sum of two primes. It鈥檚 funny, sad and even teaches you a bit of
number theory. And if you do solve Golbach鈥檚 conjecture, you may win a million
pounds. Published by Faber & Faber, 拢9.99, ISBN 0571202039.
