Did you know? The oldest computer was built more than 2,000 years ago. The Antikythera mechanism is the world's oldest analog computer. It was built in ancient Greece around 100 BC to predict celestial movements and eclipses. It has 30 gears, each with a different diameter, and it shows the position of the sun and moon relative to the earth in the sky throughout the year. It also showed where planets were at certain times of the year and could even predict solar and lunar eclipses. #shorts #short #history
