"[This book presents] to the non-mathematician what is indeed the greatest unsolved problem in pure mathematics, describing its history, the men who have contributed to its understanding, and their motivation for tackling it . . . Lively, full of anecdotes, and fun to read. The reader will find in [this book] a picture not only of the Riemann hypothesis, but also of the strange world of mathematicians."—**Enrico Bombieri, ***The American Scientist*
