Antikythera mechanism
eveloped by Greek astronomers during the second century BC
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. 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 [SEP] Origin
The Antikythera mechanism is generally referred to as the first known analogue computer. The quality and complexity of the mechanism's manufacture suggests that it must have had undiscovered predecessors made during the Hellenistic period. Its construction relied on theories of astronomy and mathematics developed by Greek astronomers during the second century BC, and it is estimated to have been built in the late second century BC or the early first century BC. In 1974, Derek de Solla Price concluded from gear settings and inscriptions on the mechanism's faces that it was made about 87 BC and lost only a few years later.
