Astronomy from Ptolemy to GalileoIt has been said that Astronomy has always been the first intuition to develop in all civilizations . This is non surprising visual detection how the sunshine woolgather and stars are such an ever slacken part of our daily lives . From the moment man first nonices the coach of day and night , he is already making an astronomic 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 majesty and grandness of the sky , it is not surprising that early man gave equally grand and lordly explanations for the sky and its motions . Drums would beat during eclipses in to scare away the super acid bitartrate that swallowed the Sun . They noticed stars that varied positions - planets - and gave these wand erers names reserved for the mightiest of Gods . The arras of the sky formed patterns , patterns which were the most fitting resting place for any(prenominal) of the greatest heroes of legends and epicsWhile being a source of wonder , the plain stitch of force were also a source of mystery . Calendars were bony up based on the motions of the stars These same calendars helped civilizations grow and tucket as the stars told man when to plant his crops , or when the river is going to gorge that far from utility , some saw in the stars a sense of grandness . Seeing the great sun , moon about , Jupiter , and his brothers revolve around the Earth - it was clear for the early observers that he was standing in the center of the Universe and that everything else literally turn 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 aro und it Philosophers such as Hipparchus and A! ristotle have left their sop up to it on the geocentric theory .
It was however a disciple at Alexandria named Claudius Ptolemy who established a major part of the word of geocentric theoryAn important distinction between Ptolemy s work and of those in the first place him was his dedication to observation and analysis . Ptolemy himself compiled a star stand for 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 calendar 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 separately one moved in a circle as they orbit the earth - the epicycle . The epicycle would cause the planets to move farther or close set(predicate) to Earth depending on which phase of the epicycle the planet was onUsing the pattern of the epicycle , Ptolemy was adapted to account for the...If you want to get a proficient essay, holy order it on our website: OrderCustomPaper.com
