Scientists unlock mystery of 2,000-year-old computer
Scientists have unlocked the secret of an ancient device recovered from
a Roman shipwreck, saying the complex mechanism was used to track the movements of the stars and moon. The machine, believed to be about 2,000 years old, was discovered in 1901 on a shipwreck off the coast of the Greek island of Antikythera and embedded in rock. The strange wheel-like device with complex gears had baffled researchers attempting to determine its purpose. A fragment of the 2,100-year-old Antikythera Mechanism, believed to be the earliest surviving mechanical computing device, is seen at the National Archaeological Museum in Athens on Thursday. A fragment of the 2,100-year-old Antikythera Mechanism, believed to be the earliest surviving mechanical computing device, is seen at the National Archaeological Museum in Athens on Thursday. But a recent study in the journal Nature has revealed the device, known as the Antikythera Mechanism, was actually a complex means of tracking the movements of astronomical bodies for use in navigation. A team of researchers led by Mike Edmunds and Tony Freeth at Cardiff University in Wales used X-rays to peer through the deposits covering the mechanism, to uncover ancient script and clues on how the mechanism worked. "This device is just extraordinary, the only thing of its kind," said Edmunds in announcing the results. "The design is beautiful, the astronomy is exactly right. The way the mechanics are designed just makes your jaw drop. Whoever has done this has done it extremely well." The researchers will be releasing their full findings of what they are regarding as a 2,000-year-old computer at a two-day international conference in Athens on Thursday and Friday. Created between 150 BC and 100 BC, the mechanism contained 37 gear wheels in a case of wood and bronze in a contraption that resembled a clock. The gear wheels were designed to track the movements of the sun and moon, and even track eclipses and the irregular orbit of the moon. It may also have been able to follow some of the planets. Also astonishing is the machine's use of a differential gear, a device known to have been used in the 17th century but often speculated to have been invented years earlier. The device is an arrangement of gears that permits the rotation of two shafts at different speeds. It is most commonly associated in modern usage with automobiles, which use a differential gear on their rear axle to allow different rates of wheel rotation on curves. The intricacy of the device is also comparable to that of 18th-century clocks. 'State of the art in astronomy' "I'm very surprised to find a mechanical representation of this," Alexander Jones, an astronomy historian who works at the University of Toronto, told Nature. Jones predicts the mechanism will have a profound impact on our view of the history of science. "This was absolutely state of the art in astronomy at the time." .... see http://www.cbc.ca/technology/story/2...mechanism.html for source and more |

Scientists unlock mystery of 2,000-year-old computer(laptop)
Compared to my instant action webtv my laptop came from the Ming
dynasty. Well it does type and print,and looks nice on my desk. Gives me two email.( big shot) I might bury it in my back yard very deep,so when dug up it will be 5,000 years old and that could be the best reason for this piece of garbage Bert |

General Bohne That's exactly why they all preferred not to think about it. They could not deny it's existence, but they considered it some freak object.. and would have even preferred to assume that it had fallen there from an other dimension or thru time itself :- nightbat Yes General Bohne very much like the coffee boys, Saul, and Sidewalk guy when presented with historical recorded far advanced knowledge. Raving I had no inking that such complicated and evolved mechanisms were constructed at that time. I suppose the intricacy is consistent with the craftsmanship skills required to make some of the jewelry. The advanced knowledge of a mechanical device still surprises me. Are there (m)any other examples of such things? General Bohne Not to my knowledge. Cordially, Raving Cordially 2, C. nightbat The Seans via Darla have informed of their helping humans throughout history, so nothing new. The Romans burnt down the library at Alexandria out of fear of documented super advanced knowledge base logged there. The Roman foot soldiers more then likely saved secret useful mechanisms as acquired bounty from higher ranked Legion leaders knowledge at great risk of possible loss of life or freedom. The loss of the great Egyptian Library no doubt left much history void to many strange advanced concepts and inventions common to Darla Sean reported visited civilizations. The Great Sphinx of Giza is also one of the greatest mysteries unmoved for centuries. See: http://search.netscape.com/ns/boomfr...%2Fsphi nx%2F Also: http://search.netscape.com/ns/boomfr...%2Fmpl_3_3.htm And: http://www.planetarymysteries.com/egypt/sphinxmars.html Where the possible Sean Starship by Egyptians was buried is anyone's guess, but under the Great Sphinx is a possibility. ponder on, the nightbat |
