Decoding the Heavens: A 2,000-Year-Old Computer -- and the Century-Long Search to Discover Its Secrets
by possibly noteworthy at 7:51 am EDT, May 11, 2009

Publishers Weekly Starred Review:

Jo Marchant, editor of New Science, relates the century-long struggle of competing amateurs and scientists to understand the secrets of a 2000-year-old clock-like mechanism found in 1901 by Greek divers off the coast of Antikythera, a small island near Tunisia.

With new research and interviews, Marchant goes behind the scenes of the National Museum in Athens, which zealously guarded the treasure while overlooking its importance; examines the significant contributions of a London Science Museum assistant curator who spent more than 30 years building models of the device; and the 2006 discoveries made by a group of modern researchers using state-of-the-art X-ray. Beneath its ancient, calcified surfaces they found "delicate cogwheels of all sizes" with perfectly formed triangular teeth, astronomical inscriptions "crammed onto every surviving surface," and a 223-tooth manually-operated turntable that guides the device.

Variously described as a calendar computer, a planetarium and an eclipse predictor, Marchant gives clear explanations of the questions and topics involved, including Greek astronomy and clockwork mechanisms. For all they've learned, however, the Antikythera mechanism still retains secrets that may reveal unknown connections between modern and ancient technology; this globe-trotting, era-spanning mystery should absorb armchair scientists of all kinds.
