It was however a learner at Alexandria prognosticated Claudius Ptolemy who established a major part of the information of geocentric theoryAn important distinction between Ptolemy s work and of those in front him was his dedication to reflexion and analysis . Ptolemy himself compiled a star graph detailing the positions and magnitudes of 1 ,022 stars . To aid him in his numeration , he constructed what is arguably the first astronomical instrument - the astrolabeHowever card was not enough to set apart Ptolemy in the history books Ptolemy is take up remembered for the geocentric scheme that bears his name . In the Ptolemaic system , the moonlight , planets , and the Sun revolved around the Earth in concentric orbits . This explained the east to western hemisphere motion of the heavenly bodies . save , the planets severally moved in a circle as they orbit the earth - the epicycle . The epicycle would pay off the planets to move farther or snuggled to Earth depending on which phase of the epicycle the planet was onUsing the imagination of the epicycle , Ptolemy was up to(p) to account for the...If you lack to get a replete(p) essay, prescribe it on our website: Ordercustompaper.com
