Nova: Ancient Computer

An unpromising lump of metal found in a 2,000-year-old shipwreck turns out to be an extraordinary treasure: The world's first computer. Nova follows the ingenious detective work that painstakingly discovered the truth about the ancient Greek device: it was an astonishingly sophisticated astronomical calculator and eclipse predictor, unrivaled until the era of modern science and believed to be from the workshop of Archimedes.
