Why did Claudius ptolemy theory his geocentric model?
Claudius Ptolemy developed his geocentric model, known as the Ptolemaic system, to explain the observed movements of celestial bodies from an Earth-centered perspective. He sought to account for the apparent retrograde motion of planets and the varying brightness of stars through a complex system of epicycles and deferents. Ptolemy's model was widely accepted for over a millennium because it aligned with the philosophical and religious views of the time, positioning Earth as the center of the universe. Additionally, it provided a framework that could predict planetary positions, making it useful for astronomical observations.
How was Ara the constellation discovered?
Ara constellation in the Southern Hemisphere was discovered by the Greco/Roman/Egyptian astronomer Ptolemy in the 2nd cenury AD.It is one of the 48 knowm constellations first identified and recorded by Ptolomy.He used fairly primitive equipment in his observations and was meticulous in recording his findings,and remains the most prolific astronomer of our heavens
What roman scientist said earth was center of the universe?
Ptolemy.
Who first believed the sun went around the earth?
ptolemy
Who introduced the idea of ellipitical orbits in geocentric theory?
The idea of elliptical orbits in the geocentric theory was introduced by the ancient Greek astronomer Claudius Ptolemy, who proposed a complex system of epicycles and deferents to explain the observed motion of celestial bodies.
Where did Ptolemy do his observations?
he studied at barnes and noble
Where and when did ptolemy make his astronomical observations?
Ptolemy would have made his observations in Egypt probably Alexandria around AD120 up to his death in AD168.
When did ptolemy start his observations?
late 1500's
Did Galileo's observations confirm the validity of retrograde motion of the planets?
No, Ptolemy did.
When and where did Ptolemy make his astronomical?
Ptolemy would have made his observations in Egypt probably Alexandria around AD120 up to his death in AD168.
Who developed ideas that contradicted Ptolemy's geocentric model of the universe?
Copernicus and Galileo were two major figures whose ideas contradicted Ptolemy's geocentric model. Copernicus proposed a heliocentric model with the Sun at the center of the solar system, while Galileo used observations through a telescope to support this view and challenge Ptolemaic beliefs.
Is it true that in the late 1500s Ptolemy's observations were supplanted by those of later Greek astronomers?
Later polish astronomers
How did Ptolemy make his astronomical observations?
Im thinkin that it was made when he decided to look up at the sky one night and decided he would make an astronomical observation. idk just that's how i would make an oservation of the sky. [Rosco P. Coltrain]

What experiments did Ptolemy do?
Ptolemy, the ancient Greek astronomer and mathematician, is best known for his work in developing the geocentric model of the universe, rather than conducting experiments in the modern sense. His major contributions came from meticulous observations and calculations of celestial bodies, which he documented in works like the "Almagest." He relied on observations of planetary movements and the stars to support his theories, but he did not perform experiments as we understand them today. Instead, his approach combined empirical observations with mathematical reasoning to explain celestial phenomena.
What was the name of Cleopatra's brother?
Cleopatra had two brothers and they were both named Ptolemy. Ptolemy XIII and Ptolemy XIV.Cleopatra had two brothers and they were both named Ptolemy.

What evidence did Ptolemy have?
Ptolemy used observational data gathered by previous astronomers, such as Hipparchus, to develop his geocentric model of the universe. He believed that the Earth was at the center of the universe based on observations that celestial bodies moved in complex patterns in the sky.
