The Antikythera mechanism is an odd astronomical calculator. It was found in a shipwreck off the Greek island of Antikythera in 1900, and is astoundingly advanced. It was a bronze clockwork gadget with at the very least 30 gears, and appears like one thing from the 1400s. However latest analysis signifies that it probably dates sooner than 200 B.C.
Due to its anachronistic nature, it’s typically related to historical aliens or the misplaced metropolis of Atlantis, however the gadget itself doesn’t calculate something historical astronomers didn’t already know. By that point observational astronomy was fairly refined. The manufacture of the gadget additionally doesn’t make the most of any building strategies that weren’t recognized on the time. What’s astounding is that this astronomical information and manufacturing was mixed to create a precision transportable calculator.
Though discovered on a Greek ship and having Greek engravings, the structure of the gadget follows Babylonian astronomy. The gadget calculated the Egyptian photo voltaic calendar, in addition to the Metonic lunar calendar. It predicted photo voltaic eclipses, and even calculated the timing of the Olympic video games. It even calculated the positions of the Solar, Moon and planets alongside the ecliptic. The planetary positions will not be notably correct, since they use the Greek mannequin of completely round orbits. Nonetheless, it’s an astounding demonstration of human ingenuity.
Given its sophistication, there are probably even earlier variations that have been constructed, although now we have by no means discovered the rest prefer it. How such a calculating gadget was developed, and when that information was misplaced, stays a thriller.
