WebPtolemy used epicycles to explain the retrograde motions of planets. (His estimate of the Moons distance was roughly correct, but his figure for the solar distance was only about a twentieth of the correct value.) But the eccentric motions adopted by Ptolemy were just approximations to the true motions of the planets and over the centuries the errors began to accumulate. Infer where continental crust is the thickest. What is not disputed, however, is the mastery of mathematical analysis that Ptolemy exhibited. If the duration of the time intervals are the same (meaning t2 t1 = t4 t3 = t6 t5), how are the sizes of these areas related?

Because one half of an epicycle runs counter to the general motion of the deferent path, the combined motion will sometimes appear to slow down or even reverse direction (retrograde).

Defending the theory that vision is due to a flow emanating from the eye, Ptolemy analyzed the reflection of light on flat and spherical mirrors, and its refraction when it crosses the surface between two transparent media. He discovered that if he represented the motions of the Sun, the Moon, and the five known planets with spheres, he could nest them inside one another with no empty space left over and in such a manner that the solar and lunar distances agreed with his calculations. So when Copernicus came along with the cor- rect heliocentric system, his ideas were fiercely opposed by the Roman Catholic Church because they displaced Earth from the center, and that was seen as both a demotion for human beings and contrary to the teachings of Aristotle.

In order to explain the motion of the planets, Ptolemy combined eccentricity with an epicyclic model. In the Ptolemaic system each planet revolves uniformly along a circular path (epicycle), the centre of which revolves around Earth along a larger circular path (deferent).

He introduced epicycles. Beyond the Sun, he thought, sat Mars, Jupiter and Saturn, theonly other planets known at the time (as they were visible to the naked eye).

Watching his astronomers laboriously calculate motions of epicycles upon epicycles, he commented that had he been present at the creation, he could have suggested a simpler arrangement. In 1444 Nicholas of Cusa again argued for the rotation of the Earth and of other heavenly bodies, but it was not until the publication of Nicolaus Copernicuss De revolutionibus orbium coelestium libri VI (Six Books Concerning the Revolutions of the Heavenly Orbs) in 1543 that heliocentrism began to be reestablished.

Ptolemy, Latin in full Claudius Ptolemaeus, (born c. 100 cedied c. 170 ce), an Egyptian astronomer, mathematician, and geographer of Greek descent who flourished in Alexandria during the 2nd century ce. In several fields his writings represent the culminating achievement of Greco-Roman science, particularly his geocentric (Earth-centred) model of the universe now known as the Ptolemaic system. However, if the paths centre is displaced from Earth, the body will sweep out equal angles in unequal times (again, from a terrestrial perspective), moving slowest when farthest from Earth (apogee) and fastest when nearest Earth (perigee).
