Caught over the weekend ... Mysteries of computer from 65BC are solved. “Detailed imaging of the mechanism suggests it dates back to 150-100 BC and had 37 gear wheels enabling it to follow the movements of the moon and the sun through the zodiac, predict eclipses and even recreate the irregular orbit of the moon. The motion, known as the first lunar anomaly, was developed by the astronomer Hipparcus of Rhodes in the 2nd century BC, and he may have been consulted in the machine’s construction, the scientists speculate. Remarkably, scans showed the device uses a differential gear, which was previously believed to have been invented in the 16th century.”
