"A remarkable book"

That is a quote from John Nash about a book I looked at recently - Prime Obsession by John Derbyshire.

On page (ix) he states the Riemann hypothesis, that the non-trivial zeros of the zeta function have real part one half.

It is not till page 146 that he describes how to calculate any value of zeta(z) with real part of z less than 1.

But the most remarkable thing about the book is that I don't see (in my superficial reading) a description of how one would calculate even one non-trivial zero of the zeta function.

I must be mistaken, and am happy to be corrected.
