Scientists say that they have figured out the arrangement and functions of nearly all the parts of a mysterious mechanical gadget that was discovered a century ago in a 2,000-year-old shipwreck.
Since it was found, the shoe-box-size device known as the Antikythera mechanism has amazed historians and other scholars with its advanced technology. The precision assembly contains 30 bronze gears with as many as 224 presumably hand-cut teeth.
