Ptolemy

Not much is known about Ptolemy's childhood, as historical records are limited. He was born in Egypt around 90 AD and came from a wealthy and influential family. It is believed that he received a well-rounded education, possibly including training in mathematics and astronomy that would later influence his work as a scientist.

Yes, Galileo rejected the notion of geocentrism and instead supported the heliocentric model proposed by Copernicus. Galileo's observations through his telescope provided evidence that supported a sun-centered solar system.

Latitude and longitude as a coordinate system were developed separately by Hipparchus and Ptolemy in the 2nd century BC. They both contributed significantly to the mapping and understanding of the Earth's surface, with Hipparchus focusing on latitude and Ptolemy introducing the concept of longitude.

Ptolemy's works, specifically his Geographia, had a significant impact on mapmaking in the 1400s by emphasizing the use of latitude and longitude lines, leading to greater accuracy in mapping. His maps provided a framework for cartographers to accurately depict the world and navigate more efficiently, which contributed to the Age of Exploration in the 15th century.

The maps drawn by Ptolemy and al-Idrisi revolutionized European sea exploration by providing more accurate and detailed geographic information, such as coastlines, distances, and landmarks. This enabled European explorers to plan their journeys more effectively and navigate unknown waters with greater confidence. The maps also helped expand European knowledge of the world, leading to increased exploration and trade.

Yes, Ptolemy's Geography book was a comprehensive work that combined mathematical principles with geographical knowledge. It included a grid system of longitude and latitude and provided coordinates for over 8,000 locations. This system of mapping influenced cartography for centuries to come.

After the death of Alexander the Great, Ptolemy gained control of Egypt and established the Ptolemaic Kingdom. He founded a dynasty that ruled Egypt for nearly three centuries, until it fell to the Romans in 30 BC.

Ptolomy XII, like all the Ptolomies was Greek.

The last ruler of the Ptolemaic dynasty was Cleopatra VII. She was the last pharaoh of Ancient Egypt, ruling jointly with her son, Ptolemy XV Caesarion. After the defeat of her forces by Octavian, Cleopatra committed suicide in 30 BCE.

In Spanish, "Ptolemy" is pronounced as "tolomeo."

That depends on who you ask.

The last actual Pharaoh of Egypt was a shared throne between Cleopatra VII and her son Ptolemy XV, from 44 to 30 BCE After the death of Cleopatra, Egypt became a Roman province, ruled by the Emperor of Rome.

In some cases, the Roman Emperor was also titled Pharaoh of Egypt, specifically while he was in Egypt. There is at least one Egyptian list of kings which lists the Emperors of Rome as Pharaohs for another 280 years, ending with Decius, who was Emperor from 249 to 251, CE.

But, the most common answer would be Cleopatra.

Galileo Galilei was the Italian physicist put on trial in 1633 for supporting the heliocentric model of the solar system proposed by Copernicus, which stated that the Earth revolved around the sun. This was considered heretical by the Catholic Church at the time.

The geocentric system is very plausible to people who have not looked deeply into the subject of astronomy, because at first glance, that's how things appear. We stand on a world that does not feel like it is moving. Our senses tell us that it is motionless (not counting earthquakes). It is somewhat difficult to imagine that this vast, seemingly motionless surface that we are standing on is actually moving through space. And when we look at the sky, we see various astronomical objects which rise and set, just as if they were circling the motionless Earth.

Cleopatra married Ptolemy XIV, right after the death of Prolemy XIII under orders from Caesar.

Aristotle was a Greek philosopher who made significant contributions to various fields, including ethics, logic, and metaphysics. Ptolemy, on the other hand, was an astronomer and mathematician who developed the geocentric model of the universe. While Aristotle's work influenced a wide range of disciplines, Ptolemy's contributions were mostly focused on astronomy.

Ptolemy considered the solar system (and the universe) to be a set of crystal concentric spheres rotating around the stationary Earth at its centre.

On the closest sphere was the moon, then Venus and so on out to the stars on the outer sphere. At the time they didn't have any idea how incredibly big everything is.

Eudoxus of Cnidus, a student of Plato, developed the system of concentric spheres in his attempt to explain planetary motion and the movements of the stars. This system later influenced the Ptolemaic astronomical model, which incorporated epicycles to account for observed planetary motion.

In Ptolemy's geocentric model, the sun was believed to orbit around the Earth along with other celestial bodies. The Earth was considered to be the center of the universe, with the sun, moon, and planets moving in circular orbits around it.

Aristotle believed that the Earth was at the center of the universe, with the sun, moon, planets, and stars revolving around it in perfect circular orbits. This geocentric model of the universe dominated Western thought for centuries until it was replaced by the heliocentric model proposed by Copernicus and further developed by Galileo and Kepler.

The Persian Empire was a powerful ancient civilization that was eventually conquered by Alexander the Great in the 4th century BC. After Alexander's death, one of his generals, Ptolemy, established the Ptolemaic Kingdom in Egypt, ruling as pharaoh and starting the Ptolemaic dynasty. This period marked a significant era of cultural and scientific advancement known as the Hellenistic period.

Aristotle's model of the solar system was geocentric, meaning that everything in the solar system revolved around Earth. Ptolemy added in the way the planetary bodies moved, although they still moved geocentrically.

Copernicus' model is simpler than Ptolemy's because it places the sun at the center of the solar system, with planets orbiting around it in nearly circular paths. This heliocentric model eliminates the need for complex epicycles, which Ptolemy used in his geocentric model to explain the retrograde motion of planets. Copernicus's model also provides a more elegant explanation for the observed movements of celestial bodies.

Ptolemy was born on 85 A.D

Ptolemy believed that the Earth was a stationary sphere at the center of the universe and that the Sun, Moon, planets, and stars revolved around it in perfect circular orbits. This geocentric model of the universe was accepted for centuries until the heliocentric model proposed by Copernicus.

Ptolemy believed that Venus, like other planets in his geocentric model of the universe, exhibited phases due to its position relative to the Earth and the Sun. He thought that the varying shapes of Venus as seen from Earth were caused by the changing angles between the three celestial bodies.
