From the early peoples who marvelled at the geometry of nature -- the beehive and bird's nest -- to ancient civilisations who questioned beautiful geometric forms and asked 'why?', the story of geometry spans thousands of years. Using only three simple tools -- the string, the straight-edge and the shadow -- human beings revealed the basic principles and constructions of elementary geometry. Weaving history and legend, this fascinating book reconstructs the discoveries of mathematics's most famous figures. Through illustrations and diagrams, readers are able to follow the reasoning that lead to an ingenious proof of the Pythagorean theorem, an appreciation of the significance of the Golden Mean in art and architecture, or the construction of the five regular solids. This insightful and engaging book makes geometry accessible to everyone. Readers will be fascinated with how the knowledge and wisdom of so many cultures helped shape our civilisation today. String, Straight-edge and Shadow is also a useful and inspiring book for those teaching geometry in Steiner-Waldorf classrooms.

What do the pyramids of Egypt really represent? What could have driven so many to so great, and often so dangerous, an effort? Was the motivation religious or practical? Illustrated with more than 300 photographs and drawings, this book presents an original approach to the subject of pyramid building. It reveals the connection between devices that served both a practical need for survival and a spiritual belief in gods and goddesses. It examines Egyptian technologies and techniques from the origins of pyramid development to the step-by-step details of how the ground was leveled, how the site was oriented, and how the stone was raised and placed to meet at a distant point in the sky. Here the author also asks and answers questions virtually ignored for the last century. He discloses, for example, the ancient use of shadows, now denigrated to the ornamental back-yard sundial, but once an important tool for telling the height of an object, geographical directions, the seasons of the year, and the time of day. He also reinterprets the ancient "stretching of the cord" ceremony, which once was thought to have only religious significance but here is shown as the means of establishing the sides of a pyramid.
