Copernicus, Brahe, Kepler, and Galileo - a new theory of the universe.

The old theory of the Universe, the Ptolemaic governing body, had the earth at the sum of a universe made up of coaxal spheres in spite of appearance spheres that held the moon, sun, planets and stars. To explain the observable, non-circular patterns ( relapse effect) of midland planets, Ptolemaic thinkers had to make many bungling adjustments in their systems. The planets had to be a small circle (epicycle) most a larger circle (deferent). Ptolemy used the spherical precedent because of the Aristotelian idol of circles being the perfect shape. Nicholas Copernicus, a pour down assimilator and priest, studied the motions of the planets and stars. He was also interested in reforming the schedule to provide a more accurate representation of determine the date of Easter. He published The Revolutions of the Heavenly Bodies in 1543, the category of his death. This postulated the idea of a sun- revolve arounded universe, but his hypothesis was non a end up break wit h the Ptolemaic system since he described the motion of the planets using spheres around the sun. Copernicus felt that the Ptolemaic system compromised the grand of perfect spheres too much by having to account for retral motion with offsets and spheres within spheres. For the sake of numerical elegance, Copernicus preferred to pop out the sun in the center of the universe.

His sun-centered system simplified these calculations and eliminated a large number of extraneous spheres by giving a simple geometric reason for the retrograde motion. It was a extremist idea at the condemnation to obliterate the earth from the center of the universe, and an impo! rtant platform for future thinkers to cast on. Tycho Brahe (1546-1601), a danish pastry noble, did not embrace the view of Copernicus and exhausted much of his time making observations to disprove it. Brahes system was a compromise mingled with Ptolemy and Copernicus. Brahe... If you want to get a exuberant essay, order it on our website: OrderCustomPaper.com
