Julia Diggins masterfully recreates the atmosphere of ancient times, when men, using three simple tools, the string, the straightedge, and the shadow, discovered the basic principles and constructions of elementary geometry. Her book reveals how these discoveries related to the early civilizations of Mesopotamia, Egypt, and Greece.The fabric of the story is woven out of archeological and historical records and legends about the major men of mathematics. By reconstructing the events as they might have happened, Diggins enables the attentive reader to easily follow the pattern of reasoning that leads to an ingenious proof of the Pythagorean theorem, an appreciation of the significance of the Golden Mean in art and architecture, and the construction of the five regular solids.Out of print for 34 years, Julia Diggins' classic book is back and is a must-read for middle school students or for parents helping their children through their first geometry course.

    But as animals can only be spied on by getting quite close Heinrich adopts ravens, thereby becoming a "raven father," as well as observing them in their natural habitat, studying their daily routines, and in the process painting a vivid picture of the world as lived by the ravens. At the heart of this book are Heinrich's love and respect for these complex and engaging creatures, and through his keen observation andanalysis, we become their intimates too.Throughout history there has existed an extraordinary relationship between humans and ravens. Ravens, like early humans, are scavengers on the kills of great carnivores. As scavengers, ravens were associated with hunters they found in the north: wolves and, later, men. The trinity of wolf, man, and raven in the hunt is an extremely ancient one. In considering the appeal of the raven, Bernd Heinrich suspects that a meeting of the minds might reside in that hunting trinity.Heinrich's passion for ravens has led him around the world in his research. Mind of the Raven takes you on an exotic journey--from New England to Germany, Montana to Baffin Island in the high Arctic--offering dazzling accounts of how science works in the field, filtered through the eyes of a passionate observer of nature.Heinrich has a true gift; through his stories, his beautiful writing, illustrations, and photography, the ravens come alive. Each new discovery and insight into their behavior is thrilling to read. just as the title promises, the reader is given a rare glimpse into the mind of these wonderful creatures.Following the dictum of Leonardo da Vinci--"It is not enough to believe what you see. YOU Must also understand what you see"--Bernd Heinrich enables us to see the natural world through the eyes of a scientist. At once lyrical and scientific, Mind of the Raven is bound to be a modern classic.
