Antikythera mechanism

The Antikythera mechanism is an ancient Greek device from around 150-100 BC that functions like a complex astronomical calculator. Made of bronze gears and wheels, it predicted celestial events such as solar and lunar eclipses, tracked planetary movements, and showcased the ancient Greeks' advanced understanding of astronomy. Often called the world's first computer, it demonstrated sophisticated gearwork and mechanical engineering skills. Its discovery in a shipwreck revealed how technology from over 2,000 years ago could perform precise, automated calculations related to astronomy and calendar systems.
