When was the ancient computer 'Antikythera Mechanism' made?
by
Known as the oldest complex scientific computer, the ' Machine of Antikythera ' is said to have been born in BC, but it has a structure comparable to that of 18th century watches. .. In March 2022, a team of Greek researchers published a research paper on when the oldest computer called the out-of-place artefacts , which contained technologies and insights that did not match the historical background, was made.

The bronze gear-type tool 'Machine of Antikythera' was discovered from an ancient sunken ship, and its usage and date of manufacture were unknown for a long time. Therefore, in 2005, the research project ' The Antikythera Mechanism Research Project ' (AMRP) by archaeologists, astronomyists, and historians from all over the world was launched, and the purpose of use is to read the characters written on the machine by X-ray scanning. I figured out.
The secret of 'Antikythera mechanism', which is said to be the oldest analog computer in the world, is revealed --GIGAZINE
It is analyzed that the Antikythera machine recorded and predicted the passage of time and the movement of celestial bodies, and it is believed that the measurement was performed with amazing accuracy as a small machine made in ancient times. .. In 2021, a restoration model was created to elucidate the structure of the machine, but there are still many mysterious parts.

According to a paper by a team of Greek researchers submitted to arXiv on March 28, 2022, it was possible to identify exactly when the Antikythera mechanism was built, up to the exact date and time. The research team analyzed a cycle of about 223 months called the ' Saros cycle ', which is represented by a spiral inset on the back of the device, and identified the timing of the solar eclipse and lunar eclipse measured there.
A search of the NASA database for the orbits of the Sun and Moon, which appear to have been measured by Antikythera mechanisms, revealed that they occurred on December 23, 178 BC. Therefore, it seems that the machine of Antikythera was made at the same time. Similarly, a solar eclipse is said to have occurred on December 22, 178 BC, and a team of Greek researchers said that the Antikythera mechanism played an important role for the religious priests associated with the solar eclipse. Bulgari Cital said.
In February 2022, Tony Freeth, head of the Antikythera mechanism research team at University College London (UCL),suggested that the Antikythera mechanism was designed by Archimedes in ancient Greece. bottom. There are many studies that the machine of Antikythera was made in the summer of 204 BC, and Archimedes lived from 287 BC to 212 BC, so the theory of 204 BC was considered to be promising. rice field. Bulgari Cital, meanwhile, argues that the conclusion of the summer of 204 BC does not explain why the device is prominently engraved with the Dongzhi, arguing that it is the winter of 178 BC. ..
