Synopsis

Measuring the daily and yearly cycle of the cosmos has never been entirely straightforward. The year 2000 is alternatively the year 2544 (Buddhist), 6236 (Ancient Egyptian), 5761 (Jewish) or simply the Year of the Dragon (Chinese). The story of the creation of the Western calendar, which is related in this book, is a story of emperors and popes, mathematicians and monks, and the growth of scientific calculation to the point where, bizarrely, our measurement of time by atomic pulses is now more accurate than time itself: the Earth is an elderly lady and slightly eccentric - she loses half a second a century. Days have been invented (Julius Caesar needed an extra 80 days in 46BC), lost (Pope Gregory XIII ditched ten days in 1582) and moved (because Julius Caesar had 31 in his month, Augustus determined that he should have the same, so he pinched one from February). Published with the world under threat from chaos arising from the expiry of computer dates after 31st December 1999, this study links politics and religion, astronomy and mathematics, and Cleopatra and Stephen Hawking.

Présentation de l'éditeur

The adventure spans the world from Stonehenge to astronomically aligned pyramids at Giza, from Mayan observatories at Chichen Itza to the atomic clock in Washington, the world's official timekeeper since the 1960s. We visit cultures from Vedic India and Cleopatra's Egypt to Byzantium and the Elizabethan court; and meet an impressive cast of historic personages from Julius Caesar to Omar Khayyam, and giants of science from Galileo and Copernicus to Stephen Hawking. Our present calendar system predates the invention of the telescope, the mechanical clock, and the concept ol zero and its development is one of the great untold stories of science and history.

How did Pope Gregory set right a calendar which was in error by at least ten lull days? What did time mean to a farmer on the Rhine in 800 A.D.? What was daily life like in the Middle Ages, when the general population reckoned births and marriages by seasons, wars, kings'' reigns, and saints' days? In short, how did the world
