An ex-senior curator finally succeeded in replicating all known features of the 2000 years old Antikythera mechanism, the first known mechanical computer in human history. Technically this is in similar spirit as a 19th century clock. There is some strange notion among some people regarding how people got smarter over time. Sometimes I feel like throwing the Antikythera mechanism in their faces. Or, I could just tell them to go read a good history book instead. Yes, I could always do that.
All in all, amazing mechanism. Perhaps there were even more amazing things lost to time in other ancient civilizations as well.
