"Indivisible Man": A review of books about the Riemann Hypothesis. Reviewed by Enrico Bombieri. *American Scientist*, July-August 2003.

Bombieri reviews *Prime Obsession: Bernhard Riemann and the Greatest Unsolved Problem in Mathematics* by John Derbyshire (Joseph Henry Press, 2003) and *the Riemann Hypothesis: The Greatest Unsolved Problem in Mathematics* by Karl Sabbagh (Farrar, Straus and Giroux, 2002). He notes that the books' publishers hope that the topic of the Riemann hypothesis will captivate the general public by presenting "to the nonmathematician 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." A sidebar to the book reviews is a note that *Fibonacci's Liber Abaci* is now translated into English for the first time, by Laurence E. Sigler of Bucknell University, published by Springer.
