Any model of the universe must incorporate the mechanisms determining the motion of the planets and other celestial bodies 13 Apr 2018 He believed that the Earth was the center of the Universe. The word for earth in Greek is geo, so we call this idea a "geocentric" theory. The Heliocentric Universe. Ptolemy's geocentric model worked but it was not only complicated, it occasionally made errors in predicting the movement of planets Early Models of the Universe. Motions of the Planets.

Ptolemy's work on optical phenomena appeared in Optica, the original edition of which consisted of five books. In the last book, he deals with a theory of refraction (the change in direction of light and other energy waves when they pass obliquely from a medium of one density into a medium of different density), and he discusses the refraction suffered by light from celestial bodies at various According to Ptolemy's model of the movement of celestial bodies, A. the sun is the center of the universe.

Ptolemy was an Alexandrian Astronomer and mathematician. In 150AD, he presented his model of the universe. It was a modified version of the then accepted Geocentric model of the Universe. Some of the highlights of the model were: 1. Earth is at the center of the universe and stationary. 2. Every celestial object is revolving around the Earth. 3.

In the Phaseis ( Risings of the Fixed Stars ), Ptolemy gave a parapegma , a star calendar or almanac , based on the appearances and disappearances of stars over the course of the solar year.

In his work, "De Revolutionibus Orbium Caelestium," published in 1543, Copernicus explained his new heliocentric, or sun centered, model. This was to be a new and updated take on Ptolemy's Almagest. The book offered new insight into the state of thought about the cosmos in 17th century Europe. The frontispiece to Almagestrum Novum illustrates Riccioli's evaluation of three models of the universe. Ptolemy's model took epicycles even further, using them to explain the brightening and dimming of the planets as well, by having epicycles attached to epicycles. While these epicycles did not perfectly explain the motion of the planets, it was the most accurate model until Kepler's laws simplified things. The planetary models of Ptolemy and Copernicus both used a circular orbit with a combination of epicycles to describe the path taken by each planet.

Both models used 40-50 epicycles in the (2) Greek astronomers developed a geocentric model for the universe. (3) Ptolemy (2nd cent) used epicycles to explain retrograde motion of planers.
