The Antikythera Mechanism: An Ancient Greek Computer

In 1901, sponge divers off the coast of Antikythera hauled up a corroded bronze lump from a Roman shipwreck. It took decades of research, including early X-ray imaging and modern CT scanning, to reveal that this object was a geared astronomical computer — the Antikythera mechanism. Dating to around 100 BCE, it could predict solar and lunar eclipses, track the positions of the sun, moon, and planets, and even model the irregular motion of the moon using a pin-and-slot mechanism that mimicked the epicyclic theory of Hipparchus. This episode dives into the discovery of the mechanism, the scientists who cracked its secrets — from archaeologist Valerios Stais to physicist Derek de Solla Price to the Antikythera Mechanism Research Project — and what the device tells us about Hellenistic technology and astronomical knowledge. We also explore the shipwreck itself, the cargo of luxury goods and art, and the mystery of who might have built this one-of-a-kind object. Was it Archimedes? Hipparchus? Or someone else? We walk through the inscriptions, the gear trains, the Saros and Metonic cycles, and why this discovery forced a rewrite of the history of technology. #AntikytheraMechanism #AncientGreekTechnology #HellenisticAstronomy #AntikytheraShipwreck #DerekDeSollaPrice #Hipparchus #Archimedes #BronzeGears #SarosCycle #MetonicCycle #PinAndSlot #CTScan #AstronomicalCalculator #SpongeDivers #ValeriosStais #History #FexingoHistory #AncientInventions Keep every episode free: buymeacoffee.com/fexingo
