"Scientists puzzled by ancient computer discovery"

Scientists have been amazed by the discovery of the Antikythera mechanism, a 2,000-year-old astronomical calendar that is more technically sophisticated than any other tool invented over the next 1,000 years. The device, dubbed "the first computer," was discovered inside a Greek shipwreck in 1901 and is a hand-powered time-keeping instrument that used a wing-up system to track the sun, moon and planets' celestial time. Despite being in 82 separate fragments, 3D computer modelling has helped experts at University College London solve the mystery of how the device worked, revealing a "creation of genius."
