The Universal History of Numbers: From Prehistory to the Invention of the Computer by Georges Ifrah,

The Universal History of Numbers: From Prehistory to the Invention of the Computer by Georges Ifrah,
" Ifrah’ s Book Amazes and Fascinates … It is Nothing Less than the History of the Human Race Told Through Figures." — International Herald Tribune " The Grand Story of Human Ingenuity." — Le Figaro A riveting history of counting and calculating from the time of the cave dwellers to the late twentieth century, The Universal History of Numbers is the first complete account of the invention and evolution of numbers the world over. As different cultures around the globe struggled with problems of harvests, constructing buildings, educating their citizens, and exploring the wonders of science, each civilization created its own unique and wonderful mathematical system. Dubbed the " Indiana Jones of numbers, " Georges Ifrah traveled all over the world for ten years to uncover the little-known details of this amazing story. From India to China, and from Egypt to Chile, Ifrah talked to mathematicians, historians, archaeologists, and philosophers. He deciphered ancient writing on crumbling walls; scrutinized stones, tools, cylinders, and cones; and examined carved bones, elaborately knotted counting strings, and X-rays of the contents of never-opened ancient clay accounting balls. Conveying all the excitement and joy of the process of discovery, Ifrah writes in a delightful storytelling style, recounting a plethora of intriguing and amusing anecdotes along the way. From the stories of the various ingenious ways in which different early cultures used their bodies to count and perfected the use of the first calculating machine— the hand— to the invention of different styles of tally sticks, up through the creation of alphabetic numbers, the Greekand Roman numeric systems, and the birth of modern numerals in ancient India, we are taken on a marvelous journey through humankind’ s grand intellectual epic.
