The Athikythera Mechanism is a device discovered a century ago and only recently scietists have managed to solve the anigma of how it worked. It was used to calculate Eclipses and planetary motions.

This can mean that the ancient Greeks of the hellinistic times were a lot more technologically advanced than we thought. We might need to rewrite the history of who really discovered gravity. Newton or Hypparchos two centuries BC?

I found this very intersting.
