Mon. 20th July: a 2,000 year old machine

In 1900, a Greek sponge diver found a metal object wrapped up in coral off the island of Antikythera. He carried it to the surface and it was examined by historians, but its true nature wasn’t really discovered until the 1950s. Even then, the scientists working on it did not truly understand its purpose. It has only been in the last few years, using high tech X-ray equipment, that they have discovered that it is in fact a sophisticated clock like mechanism, with complex internal gears worked by cogs – using more advanced technology than anything known to have been produced until the 14th Century! It has been dated to approx. 100-150 BC. Watch the fascinating Nature video on it here
