One would have to have more knowledge and enthusiasm for figures and mathematical processes to enjoy this; and such was not the case with the previous popularization of mathematics, Mathematics for the Million. But, granted that squaring the circle and monkeying with logarithms, sines and cosines, calculus and the rest of the tribe, holds fascination, this book is your meat. The authors almost succeed in making me wish I'd not forgotten more than I ever knew; but they don't tempt me to experiment as Hogben did. The puzzles, the deductive reasoning, the cryptograms which they introduce, supply a game element which will catch the imagination of those with any of the tools in sharpened form. 170 diagrams and drawings, a ready wit and an original appraoch all add to the chances of the book.
