your birthday.
The Antikythera Mechanism
The Antikythera Mechanism is a hand-cranked device that models the sky. Found in a Greek shipwreck, it dates back 2,000 years, showing technology far more advanced than previously thought for that era. X-ray images have confirmed its function as an astronomical calculator, predicting lunar and solar eclipses and planetary positions.
