# How many gears does the Antikythera Mechanism have?

## How many gears does the Antikythera Mechanism have?

30 gears
Mechanism of operation In total, 30 gears were found. One gear is probably part of a planetary display, that has been lost.

## How would the Antikythera Mechanism have measured the movements of the stars?

The Antikythera Mechanism: the ancient Greek computer that mapped the stars. Built over 2,000 years ago, the Antikythera mechanism calculated the movement of the Sun, Moon and planets using a system of dials and gears.

How many teeth does the Antikythera Mechanism have?

223-tooth
Both are connected to the 223-tooth gear, which keeps track of the Moon’s orbit. 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.

Is there a working Antikythera Mechanism?

Michael Wright, a former curator at the Science Museum in London, has built a replica of the Antikythera, which works perfectly. That’s right: The Antikythera mechanism is not only the world’s oldest computer, it’s also the world’s first green computer.

### How large is the Antikythera Mechanism?

The Antikythera Mechanism was a portable (shoe-box size, approximately 330 mm tall, 180 mm wide and at least 80 mm from front to back; Fig. 1), geared mechanism, made of bronze, and was protected by two bronze covers and a wooden case4.

### Who invented Antikythera Mechanism?

Hipparchus
7. The inventor of trigonometry may have also created the Antikythera mechanism. Hipparchus is primarily known as an ancient astronomer; he was born in what is now Turkey around 190 BCE and worked and taught primarily on the island of Rhodes. His works survive almost entirely through later Greek and Roman authors.

What is Edmunds argument in Antikythera mechanism?

They came to believe that nature worked according to predefined rules, like a machine—an approach that forms the basis of our modern scientific views. Edmunds argues that this “mechanical philosophy” must have developed as a two-way process.

What was the Antikythera used to predict?

The ancient Greek astronomical calculating machine, known as the Antikythera Mechanism, predicted eclipses, based on the 223-lunar month Saros cycle. It also implies the existence of lost lunar eclipse inscriptions.

## Has anyone recreated the Antikythera Mechanism?

Researchers Re-Create the Antikythera Mechanism, the World’s Oldest Computer. Researchers believe they’ve finally recreated what’s often considered the world’s oldest computer.

## Has the Antikythera Mechanism been replicated?

The Antikythera Mechanism has been recreated in a computer simulation—yet enigmas still remain. A fragment of the Antikythera Mechanism at the National Archaeological Museum, Athens, Greece. Photo courtesy of the National Archaeological Museum, Athens, Greece.

Who made antikythera?

It is thought by some that it was probably made by someone of the Hipparchos school. Hipparchos (c. 190 BC – c. 120 BC) was a Greek, astronomer, geographer, and mathematician of the Hellenistic period.

### What can we learn from the Antikythera mechanism?

Solving this complex 3D puzzle reveals a creation of genius—combining cycles from Babylonian astronomy, mathematics from Plato’s Academy and ancient Greek astronomical theories. The Antikythera Mechanism is a cultural treasure that has engrossed scholars across many disciplines.

### Was the Antikythera mechanism the first analogue computer?

However, there appears to be little evidence that it was part of the Mechanism; it is more likely that the disc was a bronze decoration on a piece of furniture. The Antikythera mechanism is generally referred to as the first known analogue computer.

What was found on the Ancient Greek island of Antikythera?

This wreck of a Roman cargo ship was found at a depth of 45 metres (148 ft) off Point Glyphadia on the Greek island of Antikythera. The team retrieved numerous large artefacts, including bronze and marble statues, pottery, unique glassware, jewellery, coins, and the mechanism.

Who discovered the Antikythera shipwreck?

Derek J. de Solla Price (1922–1983) with a model of the Antikythera mechanism Captain Dimitrios Kontos (Δημήτριος Κοντός) and a crew of sponge divers from Symi island discovered the Antikythera shipwreck during the spring of 1900, and recovered artefacts during the first expedition with the Hellenic Royal Navy, in 1900–01.
