what is that mechanism?
an ancient Greek hand-powered orrery, used to predict astronomical positions and also track the four-year cycle of athletic games which was similar to an Olympiad
Antikythera mechanism
an ancient Greek hand-powered orrery, described as the first analogue computer, the oldest known example of such a device used to predict astronomical positions and eclipses for calendar and astrological purposes decades in advance. It could also be used to track the four-year cycle of athletic games which was similar to an Olympiad, the cycle of the ancient Olympic Games.
what does noble gas mean? Odorless, colorless, monatomic gases with very low chemical reactivity. who discovered the first nobel gas? Pierre Janssen and Joseph Norman Lockyer and which was it? Helium who is the former by profession? A French astronomer what kind of work does the astronomers do? They observe astronomical objects such as stars, planets, moons, comets and galaxies who are the amateurs in this profession? Some devote a few hours a month to stargazing and reading the latest developments in research, others assist professional astronomers in research. what academic background does it need? PhD in physics or astronomy from where did the latter term derive? Astron means star and nomia means law, mention some instances when such studies were done in ancient times? The Antikythera mechanism (c. 150–80 BC) was an early analog computer designed to calculate the location of the Sun, Moon, and planets for a given date.

Antikythera mechanism [SEP] Introduction
The Antikythera mechanism ( ) is an ancient Greek hand-powered orrery, described as the first analogue computer, the oldest known example of such a device used to predict astronomical positions and eclipses for calendar and astrological purposes decades in advance. It could also be used to track the four-year cycle of athletic games which was similar to an Olympiad, the cycle of the ancient Olympic Games. This artefact was retrieved from the sea in 1901, and identified on 17 May 1902 as containing a gear by archaeologist Valerios Stais, among wreckage retrieved from a shipwreck off the coast of the Greek island Antikythera.
