Given that the ancient Greeks established the foundation of Western civilization, it's hard to overstate their significance in world history. But according to a newly published study of a Greek astronomical computing device built between 150 and 100 BC, they were even more technologically advanced than classical scholars have realized.
The device, made of bronze and encased in wood, was found by divers off the Mediterranean island Antikythera in 1900. Scientists have studied the so-called Antikythera Mechanism for decades, but in paper published in the November 30th Nature, an international team led by Mike Edmunds and Tony Freeth (Cardiff University, Wales) report detailed studies using high-tech tools. Three-dimensional X-ray tomography enabled the scientists to count individual teeth in at least 30 precision, hand-cut gears. The group also conducted high-resolution surface imaging of many of its 80 fragments, which allowed the scientists to decipher new Greek inscriptions
