how did the antikythera mechanism work

... Then came the Antikythera mechanism, which is commonly known as the first example of such analogue computers. The Antikythera Mechanism doesn't work, it can't work, engineers are unanimous in concluding that it's simply impossible to make it work given the physical evidence (the actual gears) and yet there's dozens of working "Reproductions" and countless claims regarding it endless Appearance and Operation. The parts of the mechanism that have survived are seven large fragments and 75 small pieces, although it’s not entirely clear whether all of these small pieces belong to the mechanism. The Discovery 2. It was discovered by sponge divers off Point Glyphadia on the Greek island of Antikythera in 1900.. In 2013, Hublot presented the «Antikythera SunMoon» watch, a unique edition of 20 pieces featuring a simplified and miniaturised version of the original mechanism, in honour of this masterpiece of Antiquity.The result is a movement containing 295 components and 7 complications.

Replaced the steering pulley on the slow shaft with a 40-tooth gear, linked that to a second 40-tooth on the motor drive shaft, and was good to go. The Antikythera Mechanism’s Mechanics. [00:33.29] The Antikythera Mechanism was found a hundred years ago, underwater in an ancient Greek shipwreck in the Mediterranean Sea. Fifty years later scholars slowly began to unlock its ancient mystery.The Antikythera mechanism is the oldest known scientific calculator. A full scale reconstruction of the Antikythera mechanism Height 12.25 inches . The Antikythera Mechanism has been called an “ancient calculator,” but there is so much more to it than meets the eye. The device seemed to have a range of interlocking gears made of bronze and a hand crank to give a turning movement to the geared mechanism, plus a display that showed information about the moon, sun and planets against a … According to latest research results, Antikythera mechanism was likely also used as a geocentric planetarium, giving a cosmic view of that era. A number of gears worked together, much like they do in a mechanical clock.The device could predict astronomical positions, eclipses, the motions of the sun, the moon and probably some of the planets. It was considered to be the first mechanism with gears in human history. The Mechanism of Antikythera is the oldest, the only and in fact the very best known example of a complex astronomical device, a dedicated analogue astronomical computer, possibly a … The Antikythera Mechanism was found by divers in 1901, and many died while performing the search. A 2,000 year old Greek shipwreck contained the Antikythera Mechanism, a mechanical computer that was 1,000 years ahead of its time. An Extraordinary Machine Chapter Menu 1. The device is over 2,000 years old. The Antikythera mechanism on display at the National Archaeological Museum in Athens. Virtual model of the (still) mysterious Antikythera Mechanism by Mogi Vicentini based on the theoretical and mechanical model by Michael Wright. The Antikythera Mechanism is an astronomical calculator made by the ancient Greeks in 200 BC that was capable of indicating the timing and characteristics of eclipses, positions of the sun and moon… Mechanism and was convinced that we had to inspect it. How did our view of the Universe develop? Considering that Mercury’s eccentricity is 3.7 bigger than moon’s, this article is discussing how Hipparchus could influenced the constructor to simulate the geocentric Mercury’s orbit. A rendering of the dial on the mechanism's front face. The Antikythera Mechanism Research Project, with experts from Britain, Greece and the United States, detected in July 2008 the word "Olympia" on a bronze dial thought to display the 76 year Callippic cycle, as well as the names of other games in ancient Greece, and probably used to track dates of … The Antikythera mechanism thus seemed to be a stunning demonstration of how the ancient Greeks had translated their most famous astronomical theory into physical wheels of bronze. The Face of the Mechanism. Originally, it contained at least 30 gears, dials, scales, axles, and pointers. A group of eleven ornate glass bowls and skyphoses (handled bowls with a base, sort of like a very broad chalice) was discovered, many of them improbably intact. By the mid-eighteenth century, a world view had developed of a system constrained by physical laws. The Antikythera mechanism and the astrolabes are considered to be the first analogue calculators (courtesy of National Archaeological Museum, Athens/Costas Xenikakis). [00:41.99] It was in extremely poor condition and in many corroded pieces— [00:46.90] but once we figured out what it was and reconstructed it, [00:50.82] well, I simply don't have the words to convey how extraordinary this find was. Little did they know it would be one of the most important scientific measuring devices ever discovered. 5. Figure 2. The Antikythera mechanism is one of the world's oldest known geared devices. While the Antikythera Mechanism is associated with antiquity, it is far from lacking sophistication. These laws, if not entirely understood, showed regularity and could be handled mathematically to provide both explanation and prediction of celestial phenomena. The front face has one large dial. seems likely that the Antikythera Mechanism also displayed some or even all of the five planets known in ancient times, but there is considerable debate about this”.5 Michael Wright had made a similar proposal and, in a mechanical tour de force, built a working model of the Antikythera mechanism that included pointers for the The Antikythera Mechanism on display in Athens (via Flickr/Stefan Geens) There were also some truly spectacular finds. On this date in 1902, Greek archaeologist Valerios Stais found a corroded chunk of metal which turned out to be part of the world's first computer and became known as the Antikythera Mechanism. The front of the Antikythera Mechanism shows seven hands (sun, moon, five planets) and a double ring scale (outside: Egyptian calendar, inside: zodiac). Many scientists originally thought the Antikythera Mechanism was a piece of navigational equipment. But by the time Tony got permission to inspect the Mechanism and Roger became involved, there were only six months left in which to do all the development work. He realised that an X-ray source powerful enough to inspect the Mechanism would have many other, revenue generating, applications. A 2,000-year-old computer called the Antikythera Mechanism helped the ancient Greeks understand their universe. A complex arrangement of over 30 gears could determine with remarkable precision the … A few years ago, John Gleave, an orrery maker based in the United Kingdom, decided to construct a working replica of the original mechanism. The mechanism was a compilation of more than 30 working gears made from bronze. How Did it Work 4. Who Made the Antikythera? The Antikythera Mechanism was a marvelous ancient mechanism with more than 37 gears, 17 axis, and 8 pointers. We then reconstructed two functional models of the Antikythera mechanism and in this paper we How Did the Antikythera Mechanism Work? A Classical Wonder: The Antikythera MechanismDivers exploring a Roman shipwreck off the Greek island of Antikythera in 1901 found the remains of a baffling device. Scanning the Layers 3. The Antikythera mechanism was similar in size to a mantel clock, and bits of wood found on the fragments suggest it was housed in a wooden case. After a careful examination of the Antikythera Mechanism CT scans from AMRP, we designed and constructed the mechanical parts that are visible on the scans. The Antikythera wreck (Greek: Ναυάγιο των Αντικυθήρων) is a Roman-era shipwreck dating from the second quarter of the first century BC.. He was formerly an expert on … The Antikythera mechanism is one of the most mysterious objects in the history of civilisation. New, 5 comments. Research articles on the clock offer loose context for what the device is and what is does, but virtually none tackle the outstanding hard questions - who made it and where did its inherent astronomical and mechanical knowledge come from? NARRATOR: Michael Wright makes things, from musical instruments to a working model of the Antikythera Mechanism. The mechanism appears to have been housed in a 20-centimeter-tall rectangular box with dials on the front and back, and a small rotating handle on the side. Since its discovery in a shipwreck near Greece in 1900, an ancient metallic astronomical clock, called the ‘Antikythera Mechanism’ still baffles scientists. The Antikythera mechanism is a mechanical calculator.It was an Ancient Greek analogue computer and orrery.It was discovered in 1902 in a shipwreck off the coast of Antikythera, Greece.
