Advanced Imaging Reveals a Computer 1,500 Years Ahead of Its Time [io9.com]
X-rays and advanced photography have uncovered the true complexity of the mysterious Antikythera mechanism, a device so astonishing that its discovery is like finding a functional Buick in medieval Europe.
In 1900, some divers found the wreck of a Roman vessel off the Greek island of Antikythera. Among the other treasures remanded to the Greek government was an unassuming corroded lump. Some time later, the lump fell apart, revealing a damaged machine of unknown purpose, with some large gears and many smaller cogs, plus a few engraved words in Greek. Early studies suggested it was some type of astronomical time-keeping device – researcher Derek J. de Solla Price laid the groundwork by establishing initial tooth counts and suggesting that the device followed the Metonic cycle, a 235-month pattern commonly used to predict eclipses in the ancient world.
