2003*The Music of the Primes*.*Finding Moonshine*. 2008- [
*The Number Mysteries*.] 2009

I was describing to a mathematician friend how much I had enjoyed *Dr.
Riemann's Zeros*. Read *The Music of the Primes*, they
said; it's even better. I did, and it is.

It covers the same topic: prime numbers in general, and the Riemann
Hypothesis in particular. But this is written by a mathematician, and a
feeling for the actual meaning of some of the results comes through more
clearly. This is an essentially historical treatment, from Euclid to the
current day, building up an exciting story of our growing understanding of
primes, together with how and why the style of mathematics has changed
over the centuries. My only complaint is that I would have liked more
mathematics; there is significantly less here than in *Dr. Riemann's
Zeros*. However, the illuminating metaphor of music is used
consistently, and manages to build a coherent picture and feel for the
underlying structures. Recommended.
