Decoding the Heavens: Solving the Mystery of the World’s First Computer

In 1900 a group of sponge divers blown off course in the Mediterranean discovered an Ancient Greek shipwreck dating from around 70 BC. Lying unnoticed for months amongst their hard-won haul was what appeared to be a formless lump of corroded rock. It turned out to be the most stunning scientific artefact we have from antiquity. For more than a century this 'Antikythera mechanism' puzzled academics. It was ancient clockwork, unmatched in complexity for 1000 years - but who could have made it, and what was it for? Now, more than 2000 years after the device was lost at sea, scientists have pieced together its intricate workings and revealed its secrets.
