Tuesday 28 July 7.00pm–8.30pm
Decoding the heavens
Speaker: Jo Marchant
In 1900, a group of sponge divers blown off course in the Mediterranean discovered an ancient shipwreck, dating from around 70 BC. Lying unnoticed for months amongst the divers' hard-won haul was what appeared to be a formless lump of corroded rock. Then it cracked open, revealing gearwheels, inscriptions and precisely marked scales - it was and still is the most stunning scientific artefact we have from antiquity. For more than a century this 'Antikythera mechanism' has puzzled academics. Author Jo Marchant will tell the story of the 100-year quest to understand this ancient computer and will explain how it used surprisingly sophisticated astronomy to accurately predict the motions of the heavens. This is a story that challenges our assumptions about technology transfer over the ages while giving us fresh insights into history itself.
