What’s the most elaborate ancient mechanism?

Did Archimedes create Antikythera mechanism?

It may well be that the Antikythera mechanism was based on a design by Archimedes.

How accurate is the Antikythera mechanism?

How accurate? It is believed that the planetary motion in the mechanism was accurate to one degree in 500 years. As mentioned above, the device included an astrological face that includes pointers for the planets Mercury, Venus, Mars, Jupiter, and Saturn, as well as the Moon.

What powered the Antikythera mechanism?

The mechanism was operated by turning a small hand crank (now lost) which was linked via a crown gear to the largest gear, the four-spoked gear visible on the front of fragment A, the gear named b1. This moved the date pointer on the front dial, which would be set to the correct Egyptian calendar day.

How old is the Antikythera mechanism?

This astronomical calendar or calculator was discovered in a shipwreck off the coast of Crete in 1901 and is more than 2,000 years old. This ancient device “predates other known examples of similar technology by more than 1,000 years,” writes John Markoff for the New York Times.

Can the Antikythera Mechanism run Doom?

The Antikythera Mechanism is one of the few things that can’t run Doom because it’s basically a clock.

What is the oldest machine?

Antikythera mechanism

Antikythera mechanism is believed to be the world’s oldest computer. The mechanism has been described as an astronomical calculator as well as the world’s first analogue computer. It is made of bronze and includes dozens of gears.

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.

Is Greek and Roman the same?

Romans appeared in history from 753 BC to 1453 while the Greeks thrived from 7000 BC (Neolithic Greeks) to 146 BC. Romans used Latin as their official language while the people of Greece spoke Greek. The Greeks made sculptures of ordinary people whose bodies were idealized like those of Gods.

Who created Antikythera Mechanism?

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.

Did the ancient Greeks invent a computer?

The hand-held device dates back 2,000 years and predicted astronomical events, such as the movement of the planets and lunar and solar eclipses, for its ancient Greek users. Its stunningly sophisticated design has led many researchers to dub the invention the world’s “first analog computer.”

What is the oldest piece of technology?

Made nearly two million years ago, stone tools such as this are the first known technological invention. This chopping tool and others like it are the oldest objects in the British Museum. It comes from an early human campsite in the bottom layer of deposits in Olduvai Gorge, Tanzania.

Has the Antikythera Mechanism been rebuilt?

Now, though, it has been rebuilt. As is almost always the way with these things, it was an amateur who cracked it. Michael Wright, a former curator at the Science Museum in London, has built a replica of the Antikythera, which works perfectly.

How many Antikythera mechanisms are there?

The Antikythera Mechanism, an ancient Greek astronomical calculator, has challenged researchers since its discovery in 1901. Now split into 82 fragments, only a third of the original survives, including 30 corroded bronze gearwheels.

How many gears are in the Antikythera Mechanism?

There are 35 gears, and seven displays. There are many hints that the device was also used to calculate and show the movement of stars, even though none of the necessary gears or displays have been found.

Is the Antikythera Mechanism a calendar?

Previous research on the Antikythera Mechanism established a highly complex ancient Greek geared mechanism with front and back output dials1,2,3,4,5,6,7. The upper back dial is a 19-year calendar, based on the Metonic cycle, arranged as a five-turn spiral1,6,8.

Is the Antikythera Mechanism a clock?

The largest surviving fragment of the Antikythera Mechanism. Getty Images. Over the next few decades, painstaking analysis has gradually revealed some of the mechanism’s secrets. It turns out it’s not an actual clock – but it is an unbelievably sophisticated mechanical computer.

Who determined the location of almost 850 stars?

Hipparchus completed a star catalog of about 850 stars in 130 BC. He also constructed a celestial globe, showing the constellations and stars arranged on a sphere.

What planets were unknown to the ancient Greeks?

Five planets — Mercury, Venus, Mars, Jupiter, and Saturn were known to the ancients. To the unaided eye, these planets appear starlike. However, the planets moved relative to the stars.

Who invented trigonometry when?

Trigonometry in the modern sense began with the Greeks. Hipparchus (c. 190–120 bce) was the first to construct a table of values for a trigonometric function.

Who discovered the precession of Earth?


Hipparchus. Hipparchus, (b. Nicaea, Bithynia–d. after 127 BC, Rhodes?), Greek astronomer and mathematician who discovered the precession of the equinoxes, calculated the length of the year to within 6 1/2 minutes, compiled the first known star catalog, and made an early formulation of trigonometry.

What happens every 72 years?

During the precession, the Earth’s axis traces out an imaginary conical surface in space and a circle on the celestial sphere. The Celestial North Pole or CNP (i.e., the projection of the Earth’s axis onto the northern sky) moves about 1° along this circle every 72 years (360×72 = 26,000).

What happens every 26000 years?

Precession of Earth’s rotational axis takes approximately 26,000 years to make one complete revolution. Through each 26,000-year cycle, the direction in the sky to which the Earth’s axis points goes around a big circle. In other words, precession changes the “North Star” as seen from Earth.

Did the Egyptians study astronomy?

Egyptian civilization – Sciences – Astronomy. Like many ancient peoples, the Egyptians studied the night sky, taking measurements from the stars to accurately align their pyramids and sun temples with the earth’s four cardinal points.

Did the ancient Egyptians believe in astrology?

Astrology was very important for ancient Egyptians. They used to sharpen their sense of sight by observing the clouds float. This exercise helped them stay focus while gazing at the sky and waiting for advice or guidance from the universe. The twelve zodiac signs were based on the gods and goddesses.

Who invented astronomy in ancient Egypt?

In the 3rd century B.C., Eratosthenes was a Greek astronomer working in Egypt when he noticed the Sun directly over one city cast a shadow in another city 500 miles north. Eratosthenes understood correctly that meant Earth’s surface is curved. He calculated correctly that Earth is a ball about 25,000 miles around.

What religious beliefs did the ancient Egyptians have that made them align the Great Pyramid so precisely?

Pyramids were built for religious purposes. The Egyptians were one of the first civilizations to believe in an afterlife. They believed that a second self called the ka lived within every human being. When the physical body expired, the ka enjoyed eternal life.

Who mostly built the Egyptian pyramids?

the Egyptians

It was the Egyptians who built the pyramids. The Great Pyramid is dated with all the evidence, I’m telling you now to 4,600 years, the reign of Khufu. The Great Pyramid of Khufu is one of 104 pyramids in Egypt with superstructure. And there are 54 pyramids with substructure.

Why did the Egyptians stop building pyramids?

The area is “far too restricted in space, with also lots of lumps and bumps,” Dodson said. In other words, the ancient capital may have been too small and architecturally challenging to serve as the home for new pyramids. —Who built the Egyptian pyramids?

Can you enter the pyramids?

Yes. Among the Egyptian Pyramids of Giza, the Pyramid of Khufu allow tourists to visit the inside, and the only passageway is from the Grand Gallery to the King’s Chamber.
