From Amazon - "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."
Just 60 minutes in length so it's not a big investment of your time. I found my self saying, "Amazing" and "Wow" throughout the show. If you enjoy documentaries and history, this show is definitely worth 60 minutes of your life.
I'm not sure how long PBS will have the video up but you can find it on your local PBS station and at this PBS video link.
