A 2,000-year-old mechanical computer salvaged from a Roman shipwreck has astounded scientists who have finally unravelled the secrets of how the sophisticated device works. The machine was lost among cargo in 65BC when the ship carrying it sank in 42m of water off the coast of the Greek island of Antikythera. By chance, in 1900, a sponge diver called Elias Stadiatos discovered the wreck and recovered statues and other artifacts from the site.The machine first came to light when an archaeologist working on the recovered objects noticed that a lump of rock had a gear wheel embedded in it. Closer inspection of material brought up from thestricken ship subsequently revealed 80 pieces of gear wheels, dials, clock-like hands and a wooden and bronze casing bearing ancient Greek inscriptions.Since its discovery, scientists have been trying to reconstruct the device, which is now known to be an astronomical calendar capable of tracking with remarkable precision the position of the sun, several heavenly bodies and the phases of the moon.
Experts believe it to be the earliest-known device to use gear wheels and by far the most sophisticated object to be found from the ancient and medieval periods.
computer x-ray tomography and high resolution surface scanning, a team
led by Mike Edmunds and Tony Freeth at Cardiff University peered inside
fragments of the crust-encased mechanism and read the faintest
inscriptions that once covered the outer casing of themachine.
Detailed imaging of the mechanism suggests it dates back to 150-100 BC
and had 37 gear wheels enabling it to follow the movements of the moon
and the sun through the zodiac, predict eclipses and even recreate the
irregular orbit of the moon. The motion, known as the first lunar
anomaly, was developed by the astronomer Hipparcus of Rhodes in the 2nd
century BC, and he may have been consulted in the machine's
construction, the scientists speculate.
Remarkably, scans showed
the device uses a differential gear, which was previously believed to
have been invented in the 16th century. The level of miniaturisation
and complexity of its parts is comparable to that of 18th century
Some researchers believe
the machine, known as the Antikythera Mechanism, may have been among
other treasure looted from Rhodes that was en route to Rome fora

In October, 2005, a truck pulled up outside the National Archeological Museum in Athens, and workers began unloading an eight-ton X-ray machine that its designer, X-Tek Systems of Great Britain, had dubbed the Bladerunner. Standing just inside the National Museum’s basement was Tony Freeth, a sixty-year-old British mathematician and filmmaker, watching as workers in white T-shirts wrestled the Range Rover-size machine through the door and up the ramp into the museum. Freeth was a member of the A...Did an Ancient Language of Universal Symbols Exist?
A computer in antiquity would seem to be an anachronism, like Athena ordering takeout on her cellphone. But a century ago, pieces of a strange mechanism with bronze gears and dials were recovered from an ancient shipwreck off the coast of Greece. Historians of science concluded that this was an instrument that calculated and illustrated astronomical information, particularly phases of the Moon and planetary motions, in the second century B.C.The Antikythera Mechanism, sometimes calledthe world’s...Ancient Nuclear Weapons!
it really possible that the Ancient Indians had the capacity to deploy

possible, as many Ufologists claim, that awesomely powerful nuclear weapons were
actually given to the ancient Indian warriors by extraterrestrials, highly

Anthony North: In the early years of the 20th century an artifact was recovered from a shipwreck off the Greek island of Antikythera. Dated to about 80BC, it was considered a mere artifact. However in 1971 research on the Antikythera Mechanism showed it to have an intricate arrangement of gears, dials and graded plates. One theory is that it was a computing device to work out the movement of the Sun and planets. If this idea is true, then the ancients had a degree of technology way above previou...High-Tech Wars Described in Ancient Texts!

Archaeologists have unearthed the skull of a young woman in northern Greece who is believed to have undergone head surgery in the third century, Greek news media reported Wednesday. A Greek team discovered the skeleton at an ancient cemetery in Veria, with the skull including an injury that led them to conclude the surgery had been performed. "We think that there was a complex surgical intervention that only an experienced doctor could have performed," said IoannisGraikos, the ...An Ancient Greek 'Computer'

In 1901 divers working off the isle of Antikythera found
the remains of a clocklike mechanism 2,000 years old. The mechanism now
appears to have been a device for calculating the motions of stars and planets
