This book is a great way to learn some of the interesting aspects of numbers. Among some of the subjects covered include numbering systems, ciphers, angles, dimensions, and of course, algebra. This book is designed to make mathematics interesting. The science is not treated formally; abstract conceptions and uninteresting and abstruse procedures are completely avoided; yet at the same time the book is sufficiently complete so as to give a broad picture of mathematical fundamentals.
Engines of Logic is a thoroughly enjoyable mix of biographical portraits and theoretical mathematics. If, in places, the mathematical/logical ideas are not so clearly developed, we don't fault the author. In a book of this size (slim) and scope (broad), one can only hope to find a decent overview of a particular subject matter. Engines of Logic is more than decent; it is highly entertaining, informative, and thought-provoking. The great pleasure Davis took in writing it springs from every page. Davis is a fine guide through some very abstruse mathematical and computer science fields -- to which he himself has been a significant contributor. This book is a first-rate piece of popular science.
