1. Listen to the story of the discovery and check your answers.

The Antikythera mechanism is an ancient Greek device found in a shipwreck. It was about the size of a shoebox and was made of bronze gears. Scientists believe it could calculate the positions of planets and predict eclipses of the sun and moon.

Researchers studied the broken fragments with X-ray computer tomography and found at least 30 gears with up to 225 teeth. This helped them understand how the mechanism worked. It may also have shown the motions of the planets.

In short, the Antikythera mechanism was an amazing ancient computer, far ahead of its time.
