Ciilization One

Ciilization One: The World Is Not as Big as You Thought It Was, by Christopher Knight & Alan Butler, from Watkins Publishing Ltd., ISBN 1842930958. The authors tell the startling story of two scientists whose quest to crack the mystery of the "megalithic yard" - a unit of 82.966656 centimeters used to construct thousands of megalithic structures in Britain and France - led to evidence of an ancient culture predating the earliest known civilizations. Scientists of that time calculated the megalithic yard from observing Earth's rate of spin, part of an integrated system far more advanced than anything in use today.
