Ancient Greek Computer Calculated Olympics
An ancient astronomical calculator appears to show the four-year cycle of the early Greek competitions that inspired today's Olympic Games.

Newly uncovered inscriptions on the 2,100 year-old device reveal names linked to the Olympiad cycle of games once celebrated among ancient Greek city-states.

"It's a surprise to find this on what we thought was an astronomical instrument," said Alexander Jones, a science historian at New York University who coauthored a study on the findings that are detailed this week in the journal Nature.
