It was used to predict the positions of the planets and events like lunar and solar eclipses. The machine was even used to set the dates of the Olympic Games.<\/p>\n<p class=\"c-article__text\">Only a third of the scientific calculator had survived when it was discovered in a shipwreck off a Greek island in 1901. Ever since then, the scientific community has been trying to understand how it works and what it could have looked like.<\/p>\n<\/div>\n<\/div>\n<div class=\"ng-star-inserted\">\n<div class=\"ng-star-inserted\">\n<h3 class=\"c-article__title\">Piecing together the full picture<\/h3>\n<p class=\"c-article__text\">Using 3D computer modelling and an ancient Greek mathematical method, a research team at University College London (UCL) has completely recreated its design and provided answers as to how the sophisticated device was able to predict astronomical phenomena so accurately. The team\u2019s findings, including images of what it looked like and how it was constructed, were published in the journal <a href=\"https:\/\/www.nature.com\/articles\/s41598-021-84310-w\" target=\"_blank\" rel=\"noopener\">\u2018Scientific Reports\u2019<\/a>. \u201cOur work reveals the Antikythera Mechanism as a beautiful conception, translated by superb engineering into a device of genius. It challenges all our preconceptions about the technological capabilities of the ancient Greeks.\u201d Split into 82 fragments when found at the bottom of the sea, much of the device\u2019s front part was missing, which is where the complex gearing system was located. The scientists made a complete digital model, recreating the gears and nearly its entire front panel. \u201cThe Sun, Moon and planets are displayed in an impressive tour de force of ancient Greek brilliance,\u201d lead author and UCL mechanical engineering professor Tony Freeth told the <a href=\"https:\/\/www.bbc.com\/news\/science-environment-56377567\" target=\"_blank\" rel=\"noopener\">\u2018BBC\u2019<\/a>. \u201cOurs is the first model that conforms to all the physical evidence and matches the descriptions in the scientific inscriptions engraved on the mechanism itself.\u201d<\/p>\n<\/div>\n<div class=\"ng-star-inserted\">\n<h3 class=\"c-article__title\">Ancient hi-tech engineering contraption still keeping secrets<\/h3>\n<p class=\"c-article__text\">The UCL scientists and are now planning to create a full-scale replica. They are building their own physical versions to check if the design works. Still, several questions remain unanswered. Was the Antikythera Mechanism a toy, a teaching instrument, or something else? Where did the Greeks get the know-how to produce such advanced technology? It\u2019s considered <a href=\"https:\/\/www.smithsonianmag.com\/smart-news\/ancient-astronomical-calculator-even-older-we-thought-180953472\/\" target=\"_blank\" rel=\"noopener\">1 000 years more advanced<\/a> than anything else found from that time. \u201cThere\u2019s no evidence that the ancient Greeks were able to build something like this. It really is a mystery,\u201d co-author and UCL senior lecturer Adam Wojcik told <a href=\"https:\/\/www.livescience.com\/antikythera-mechanism-worlds-first-computer-modeled.html\" target=\"_blank\" rel=\"noopener\">\u2018Live Science\u2019<\/a>. \u201cThe only way to test if they could is to try to build it the ancient Greek way. And there\u2019s also a lot of debate about who it was for and who built it. A lot of people say it was Archimedes. He lived around the same time it was constructed, and no one else had the same level of engineering ability that he did.\u201d Wojcik probes even further in <a href=\"https:\/\/www.theguardian.com\/science\/2021\/mar\/12\/scientists-move-closer-to-solving-mystery-of-antikythera-mechanism\" target=\"_blank\" rel=\"noopener\">\u2018The Guardian\u2019<\/a>: \u201cIf they had the tech to make the Antikythera mechanism, why did they not extend this tech to devising other machines, such as clocks?\u201d<\/p>\n<\/div>\n<h3 class=\"c-article__title\"><span style=\"font-size: 16px;\">More information<\/span><\/h3>\n<\/div>\n<p><a href=\"https:\/\/cordis.europa.eu\/article\/id\/429442-trending-science-scientists-solve-mysteries-of-the-world-s-oldest-computer\/es\">News &#8211; CORDIS<\/a><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Another piece of the ancient computer\u2019s puzzle has been solved.
