In 1901, divers recovered an ancient geared device from the Greek shipwreck. 125 years later, the Antikythera Mechanism is still revealing secrets about ancient sciences

In 1901, divers searching a Greek shipwreck found something no one expected: a small, corroded machine packed with gears. It was the Antikythera Mechanism, built more than 2,000 years ago. At first, it looked like an ordinary relic. Then scientists began studying its intricate parts. More than a century later, the device is still changing what we know about ancient Greek astronomy, mathematics and mechanical knowledge.
