"2,000-Year-Old Computer Continues to Baffle Scientists"

The Antikythera mechanism, a 2,000-year-old astronomical calendar discovered in a Greek shipwreck, has left scientists baffled due to its technical sophistication. The hand-powered time-keeping instrument tracks the sun, moon, and planets' celestial time, as well as the moon's phases and timing of eclipses. Despite being technically behind, the device was a "creation of genius" and capable of tracking far more than expected. The device is currently in 82 separate fragments, but experts at University College London used 3D modeling to solve the mystery of how it worked.
