The ordinary lives of famous mathameticians rarely prove to be as interesting as their professional activities and such is the case with John Napier. This slim volume is, at least to my way of thinking, a disappointment in that it provides only the most superficial insight into Napier's thinking concerning the period during which he conceived the idea of the logarithm and produced the first table of such numbers.

For centuries thereafter they significantly simplified the multiplication and division of large numbers. Until the advent of the scientific calculator tables of logarithms were in wide use. Napier's contribution was recognized for its value by the major natural philosophers of his day and an indepth presentation of this aspect of his life would be a worthy contribution to the literature. Napiers bones, an abacus like device without wires or beads is also rather poorly covered in the book. The bones were the precursor of the slide rule and may, indeed, be among the earliest forms of mechanical calculators.

What there is of it is very good. Personally I'd have liked it better if it was expanded more. It might be nice to see more material about how to actually use logs in problem solving, or how logs were used in problem solving in the past.
