In astronomy Ptolemy relied somewhat on the theories and observations of previous astronomers, such as the geocentric model designed by Aristotle; to create his own model of our solar system.

Ptolemy versus Copernicus | Articles | Inference: International Review of Science In Metaphysics, the above ideas were intimately connected with the so-called 'problem' of "Universals". Naturally, this meant that material objects and events were somehow less 'real' than the abstractions that supposedly lent them their substantiality, or which constituted their "essence".

The model seen in 1. Ptolemy believed that each planet moved on a small circle, called an epicycle, and that these epicycles moved on a larger circle called a deferent.

He explained the movement of the stars by theorizing that they existed on a separate celestial sphere outside the planetary spheres.

Ptolemy was very adamant that planetary motion should be explained using only uniform circular motion. As shown in diagram 1. He theorized that there was an imaginary line connecting the center of their epicycles that would in turn, connect the Earth to the Sun. This imaginary line also ran in parallel to the radiuses connecting the other planets to their own epicycle.

Nicolas Copernicus was born in Poland in Much like Ptolemy, he studied mathematics and astronomy. Unlike Ptolemy however, who was known for his Earth-centered model of the universe, Copernicus varied radically from many of the thinkers of his time and theorized a heliocentric, or Sun-centered, model of the universe.

Write my paper for me!!! By having the Earth orbit the Sun along with the other planets he eliminated the need for numerous and large epicycles. However, he did not do away with the use of epicycles all together; in fact, they were still necessary for his model to work accurately.

As we now know, the orbits of the planets are not circular but elliptical. The Copernican model, by putting the sun at the center, and the Earth as the third planet of the inner solar system, set up the ordering of planets that we still use today.

This new ordering explained the varying degrees of brightness of the planets as seen from Earth, because it was now understood that the planets were at different distances from Earth; unlike the Ptolemaic model which theorized that the planets were all the same distance from the Earth.

Copernicus also theorized that planets with smaller orbits moved faster than planets with larger orbits. Unlike Ptolemy, who believed the stars moved on their own separate celestial sphere, Copernicus believed that the stars were fixed objects that were quite distant from Earth.

Dissertations: The Ptolemaic and Copernican models

The main differences between the Ptolemaic model and the Copernican model are their beliefs in a geocentric and heliocentric system of the universe. Both models expressed the theory that the planets had a uniform circular orbit, and therefore, both had to rely on the use of epicycles to predict the motion of the planets.

Both models were highly influential in their time, and in the years to follow; both making a significant contribution to the science of astronomy. Mind that the sample papers like The Ptolemaic and Copernican models presented are to be used for review only.

Under the geocentric model, the Sun, Moon, stars, and planets all orbited Earth. The geocentric model served as the predominant description of the cosmos in many ancient civilizations, such as those of Aristotle and Ptolemy.

the Copernican universe. In his poetry especially, Donne uses grandiose expression to describe what his speaker is feeling. Astronomical theory, therefore, with it's elaborate and infinite construction, presented itself as a perfect conceit for Donne.4/5(2).

The thunder-and-lightning example seems like a bad comparison for this kind of situation, in that the false claim is (1) easily observable to be untrue, and (2) utterly useless to the society that propagates it.

In Ptolemaic and Copernican astronomy, the number of adjustable parameters is proportional to the number of circles, so the simplicity of a model decreases as the number of circles increases.

It is not clear how one should define the simplicity of a theory.
