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.

Do we know what happened before the Big Bang?

And where is human consciousness located in the brain?

In *What We Cannot Know*, Marcus du Sautoy investigates
how leading experts in areas from quantum physics to sensory perception and
neuroscience are exploring the cutting-edge fields in science today.

In this brilliantly accessible, concise examination of the outer limits of human knowledge, Britain’s most famous mathematician explores whether there’s anything we truly cannot know.
