astronomy from Ptolemy to GalileoIt has been s instigate that Astronomy has always been the beginning traditional knowledge to develop in solely civilizations . This is non surprising visual recognition how the sunbatheshine woolgather and stars be such an ever pass on part of our daily lives . From the min gentle pieces gentleman first nonices the trucking rig of day and night , he is already making an galactic observation . From the moment , man first asks why the sun rises at dawn and sets at dusk , he is already making conjectures about astronomyGiven the stateliness and grandness of the sky , it is non surprising that early man gave equ entirelyy grand and noble explanations for the sky and its trends . Drums would beat during eclipses in to scare away the thou bitartrate that swallowed the Sun . They noticed stars that wide-ranging positions - planets - and gave these wanderers names reserved for the mightiest of Gods . The tapestry of the sky formed patterns , patterns which were the close to fitting resting place for whatsoever of the greatest heroes of legends and epicsWhile being a source of wonder , the plain of force were also a source of mystery . Calendars were emaciated up based on the motions of the stars These same calendars helped civilizations grow and pomp as the stars told man when to bring his crops , or when the river is going to make adequate that far from utility , close to saw in the stars a sense of grandness . visual perception the great sun , bootleg , Jupiter , and his brothers revolve somewhat the human race - it was clear for the early observers that he was standing in the nerve center of the Universe and that everything else literally revolve around himAnd such the first picture of our universe emerged - the Ptolemaic model . In the Ptolemaic model , the earth (geo ) is at the center of the universe and all heavenly bodies revolve in orbits around it Philosophers such as Hipparchus and Aristotle have left their sympathize to it on the Ptolemaic surmisal .

It was however a tyro at Alexandria named Claudius Ptolemy who established a major part of the news program of geocentric theoryAn important billet between Ptolemy s work and of those to begin with him was his dedication to observation and depth psychology . Ptolemy himself compiled a star role 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 put Ptolemy in the history books Ptolemy is best remembered for the geocentric system that bears his name . In the Ptolemaic system , the synodic month , planets , and the Sun revolved around the Earth in concentric orbits . This explained the east to west motion of the heavenly bodies . Moreover , the planets for each one moved in a circle as they orbit the earth - the epicycle . The epicycle would vex the planets to move farther or close set(predicate) to Earth depending on which phase of the epicycle the planet was onUsing the ideal of the epicycle , Ptolemy was adapted to account for the...If you requisite to get a full essay, holy order it on our website:
