Scientists from the Woods Hole Oceanographic Institution and Greece's Ephorate of Underwater Antiquities revisited a wreck site in Antikythera, a small island between the Peloponnese and Crete, where the world's first computing mechanism was found in 1901. The group hopes to find other mechanical devices similar to the Antikythera Mechanism, which dates from the first century B.C. and is thought to be a navigational aide, possibly used to forecast the path of planets.
