Ep 14. Ancient Computer

In Season 40 Episode 14 of NOVA, titled Ancient Computer, viewers are taken on a journey to explore a device from the ancient world that was used for complex calculations. The device known as the Antikythera mechanism is hailed as one of the most complex machines of its time. It dates back to the 1st century BCE and was found on a shipwreck that was discovered off the coast of a tiny Greek island called Antikythera.

The machine is widely believed to have been used by ancient astronomers to track the movements of celestial objects and to predict astronomical events such as eclipses. For a long time, the Antikythera mechanism remained shrouded in mystery, with very little known about it. In fact, it was not until the 1950s that the device was fully understood, thanks to the efforts of a group of researchers who spent decades studying the intricacies of its design.

Despite being more than 2000 years old, the Antikythera mechanism is a testament to the ingenuity and scientific knowledge of the ancient Greeks. The device is made up of dozens of interlocking gears and is capable of performing a range of complex calculations. While it may seem primitive by modern standards, the Antikythera mechanism was a revolutionary device for its time.

NOVA's Ancient Computer episode takes viewers behind the scenes to see how a team of scientists and historians are working to unravel the secrets of this enigmatic device. With access to state-of-the-art imaging technology, the team is able to examine the mechanism in unprecedented detail, revealing new insights into its construction, operation, and purpose.

One of the challenges facing the researchers is the sheer complexity of the machine. The Antikythera mechanism has over 30 gears, each of which is cut with incredible precision. In fact, the researchers found that some of the gears are so meticulously crafted that they have only ever been surpassed by clockmakers in the 18th century. To make things even more difficult, the gears are not arranged in a simple, linear sequence, but rather in a complex system of planetary gears that mimic the movement of the planets.

Despite these challenges, the team is making significant progress in unlocking the secrets of the Antikythera mechanism. By studying the inscriptions found on the device and comparing its movements to known astronomical events, they are slowly piecing together its true purpose. One of the most intriguing findings so far is that the mechanism was not just used to track the movements of celestial objects but may have also been used to predict the timing of the ancient Olympic games.

Along the way, viewers are treated to stunning visuals of the Antikythera mechanism, from close-up shots of its intricate gears to cross-sectional views of its complex inner workings. The team also offers insights into the broader historical context in which the device was created, highlighting the significance of ancient Greek science and technology.

Overall, NOVA's Ancient Computer episode is a fascinating glimpse into the world of ancient astronomy and the remarkable achievements of the ancient Greeks. It is a testament to the power of human ingenuity and the enduring quest for knowledge that has driven scientific inquiry for centuries. Whether you are a lover of history, astronomy, or simply appreciate the intricacy of finely crafted machinery, this episode is sure to captivate and inspire.
