Antikythera has seen a lot of Antikythera mechanism in usage over the last few thousand years, and the current population is around fifty inhabitants. This was a planetarium constructed by Posidonios. Some have said the Antikythera Mechanism is therefore proof of time travel, alien visitation, or Atlantis.
Taking all the available facts into account, the prevailing theory at the moment is that the device was a clockwork-like mechanism designed to display the progress and positions of the sun, moon, Antikythera mechanism probably all five of the other planets known at the time Mercury, Venus, Mars, Jupiter, and Saturn over a period of 19 years.
Because of its staggering cliff faces and craggy Antikythera mechanism, the tiny island has been a big hazard for all of maritime history. It also computes the seventy six-year Callippic cycle, which is four times the length of the Metonic cycle and was proposed by Greek astronomer Callippus around BC as an improvement over the Metonic cycle.
It was agreed that the crew of sponge divers who made the discovery would revisit the site and turn whatever they found over to the Greek government. This meant that the pin and slot mechanism was a differential gearing solution designed to compensate for the irregular, elliptical orbit of the Moon around the Earth.
This particular gear was crucial to reconciling the month solar year with the Accompanying the sun pointer is the moon pointer and the complex relationship of the orbits of the sun and moon as they travel through the skies are all built into the mechanism, and they are based on the following month definitions: The Metonic Dial The upper rear side of the device contains the Metonic dial with two smaller subsidiary dials on the inset: Gears from the Greeks: X-rays of the device have indicated that there are at least 30 different gears present in it.
The large lower dial has a four-turn spiral with symbols to show months in which there was a likelihood of a solar or lunar eclipsebased on the A naval historian named Konstantin Rados contested this theory, arguing that it was too complex of an instrument to be a mere astrolabe.
Minutes later you're back on board the ship, jabbering excitedly, so incoherent that Kondos thinks you have carbon dioxide poisoning. Specifically, it's one of the earliest known uses of meshing gears.
Many gears have not "survived" in one piece. Complex mechanical clockwork on a smaller scale began to appear in Central Europe around the end of the Middle Ages, and the automata that much of modern technology emerged from in the Victorian Era.
Nineteen years of twelve months each sum up to months in total which is 7 short ofand so a 13th month is added in 7 of the 19 years. This period was discovered by the ancient Babylonians when they noticed that any given eclipse will reoccur with the same characteristics every synodic months.
The rewards we gain from increasing our knowledge by studying them are inestimable. The duration of a sidereal month is roughly Hoax.* wrote: > Smile, no. If one were to attempt such a silly display of tangled thinking > in logicit would produce a sure failing mark.
13 days ago · A lost piece of the world’s oldest analog computer (the Antikythera mechanism an ancient Greek device designed to calculate astronomical position) may have been discovered. Gears from the Greeks: The Antikythera Mechanism, a Calendar Computer from Ca 80 B.c.

The Antikythera Mechanism could calculate the position of the Sun and the Moon on the sky as well as the phase of the Moon, with extraordinary precision. The Antikythera mechanism (/ ˌ æ n t ɪ k ɪ ˈ θ ɪər ə /, / ˌ æ n t ɪ ˈ k ɪ θ ər ə /) is an ancient Greek analogue computer and orrery used to predict astronomical positions and eclipses for calendar and astrological purposes decades in advance.
