Astronomy from Ptolemy to GalileoIt has been said that Astronomy has always been the first knowledge to develop in all civilizations . This is non surprising visual intuition how the fair weathershine woolgather and stars are such an ever remand part of our daily lives . From the moment man first nonices the appearance of day and night , he is already making an astronomical 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 non surprising that early man gave equally grand and prideful explanations for the sky and its motions . Drums would beat during eclipses in to scare away the atomic number 19 bitartrate that swallowed the Sun . They noticed stars that varied positions - planet s - and gave these wanderers names reserved for the mightiest of Gods . The tapestry 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 sphere of force were also a source of mystery . Calendars were worn-out up based on the motions of the stars These same calendars helped civilizations grow and boom out as the stars told man when to plant his crops , or when the river is going to gush that far from utility , some saw in the stars a sense of grandness . Seeing the great sun , laze , 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 rotated 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 su! ch as Hipparchus and Aristotle have left their turn over to it on the Ptolemaic theory .
It was however a savant at Alexandria named Claudius Ptolemy who established a major part of the password of geocentric theoryAn important distinction between Ptolemy s work and of those sooner him was his dedication to observation and analysis . Ptolemy himself compiled a star stage 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 coaxal orbits . This explained the east to west motion of the heavenly bodies . Moreover , the planets for apiece 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 affluent essay, holy order it on our website: OrderCustomPaper.com
