The Antikythera Mechanism is the world's oldest computer, calculating the stars 2000 years ago. Now modern engineers have come up with the only possible improvement...they've rebuilt it with Lego. But is this the best science video of them all?

Here's a description for this particular video:

The Antikythera Mechanism is the oldest known scientific computer. Built in Greece around 100 BCE but lost for 2000 years, it was recovered from a shipwreck in 1901. However, it wasn't until a century later that its purpose was understood: it's an astronomical clock that determines the positions of celestial bodies with extraordinary precision. 

In 2010, to celebrate the launch of Digital Science, a new division of Macmillan Publishers that provides technology solutions for researchers, Nature Video and collaborators built a fully-functional replica out of Lego. 


This amazing video is one of four entrants in a competition to determine the best science-related video. It's all part of an ongoing series on what makes a great science video by the Nature Network Team, the blog arm of the vaunted scientific journal Nature. Check out their site to see the other worthy entrants, which include slow-motion footage of bat echolocation, a look at the very first humans to colonize the British Isles, and a piece on barefoot running made by one of my old professors, who it turns out has way nicer legs than I ever would have guessed.
