More Lost Knowledge

The Antikythera Mechanism spent 2000 years at the bottom of the sea. It contains 30 interlocking gear-wheels and bears copious astronomical inscriptions. It computed and displayed the movement of the Sun, Moon and planets, and predicted eclipses. It was 1500 years ahead of its time. It may have been developed by the Greek astronomer Hipparchus around 140 BC.
“How can the capacity to build a machine so magnificent have passed through
history with no obvious effects?”
And you have to wonder, what other knowledge is lost or remains hidden?
Listen to the NPR story.
