This is a more mature and more highly specialized book than The Wonderful World. Properly used, it should make mathematics seem a live, human science to Junior High School students who are inclined to think of it in dreary terms. For here- through the discovery of the basic principles of numbers and measurements, civilization takes form. The miracle of counting, of making records, of extending this new knowledge to building and planning and sailing the seas; the interchange of knowledge between early Mediterranean civilizations; the coming of the mathematical wizards such as Galileo, Descartes, Newton and the foundations laid for mathematics as we know it today; the discovery and gradual acceptance of basic fundamentals -- all this made today's civilization possible. Adults will find this enlightening, and any youngsters with a mathematical bent will find it sheer enchantment. Over 250 pictures in full color add their own dramatization to the text. Hogben as a popularizer of science won his spurs with the inimitable Mathematics for the Million. Suggest that as a follow through if you turn up a budding mathematician with this.
