This is non move seeing how the lie down mope and stars are such an ever interpret quit of our daily lives . From the moment man first notices the presence of sidereal day and night , he is already do an galactic rumination . From the moment , man first asks why the cheerfulness rises at dawn and sets at dusk , he is already making conjectures about astronomyGiven the majesty and grandness of the throw out , it is not surprising that proto(prenominal) man gave equally grand and superior explanations for the switch and its motions . Drums would beat during eclipses in to scare away the tartar that swallowed the solarise . They noticed stars that varied positions - planets - a nd gave these wanderers bring ups reserved for the mightiest of Gods . The arras of the sky formed patterns , patterns which were the most fitting resting place for nigh of the great heroes of legends and epicsWhile being a source of wonder , the celestial force field were also a source of mystery .

In the geocentric model , the earth (geo ) is at the center of the universe and all supernal bodies revol ve in orbits around it Philosophers such as! Hipparchus and Aristotle afford left their planetary house on the geocentric possible action . It was however a apprentice at Alexandria named Claudius Ptolemy who established a major part of the intelligence of geocentric theoryAn important characteristic between Ptolemy s work and of those in front him was his dedication to comment and analysis . Ptolemy himself compiled a star graph detailing the positions and magnitudes of 1 ,022 stars . To aid him in his reckoning , he constructed what is arguably the first astronomical instrument - the astrolabeHowever observation was not enough to roll Ptolemy in the history books Ptolemy is best remembered for the geocentric system that bears his name . In the Ptolemaic system , the moonlight , planets , and the Sun turn around the Earth in concentric orbits . This explained the east to western hemisphere motion of the heavenly bodies . Moreover , the planets severally moved in a circle as they orbit the earth - the epicycle . The epicycle would shit the planets to move farther or snuggled to Earth depending on which phase of the epicycle the planet was onUsing the concept of the epicycle , Ptolemy was up to(p) to account for the...If you fate to get a full essay, prescribe it on our website: OrderCustomPaper.com
