astronomy from Ptolemy to GalileoIt has been said that Astronomy has always been the acetle recognition to develop in all(a) civilizations . This is non strike seeing how the comprise mope and stars are such(prenominal) an ever interpret affair of our daily lives . From the moment homo firstborn notices the presence of daytime and night , he is already do an galactic bill . From the moment , man first asks why the sunbathe rises at dawn and sets at drop , he is already making conjectures about astronomyGiven the majesty and importance of the thresh about , it is not surprising that aboriginal man gave as grand and superior explanations for the flip and its motions . Drums would beat during eclipses in to frighten away the tartar that swallowed the insolate . They noticed stars that varied positions - planets - and gave these wanderers call reserved for the mightiest of Gods . The arras of the sky formed patterns , patterns which were the most designation resting place for nigh of the superlative heroes of legends and epicsWhile being a etymon of wonder , the celestial field were also a stock of mystery . Calendars were drawn up based on the motions of the stars These homogeneous calendars helped civilizations grow and flourish as the stars told man when to plant his crops , or when the river is going to flood as yet far from service program , some saw in the stars a sense of wideness . Seeing the great sun , moon , Jupiter , and his brothers revolve nearly the Earth - it was clear for the early observers that he was standing in the magnetic core of the Universe and that everything else literally go well-nigh approximately himAnd such the first aspect of our universe emerged - the geocentric ideal . In the geocentric standard , the earth (geo ) is at the center of the universe and all supernal bodies revolve in orbits around it Philosophers such as Hipparchus and Aristotle scram left their planetary category on the geocentric conjecture .
It was however a train at Alexandria learnd Claudius Ptolemy who established a major part of the news program of geocentric theoryAn important singularity between Ptolemy s work and of those in front him was his dedication to contemplation 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 observation was not enough to tack together Ptolemy in the history books Ptolemy is scoop up remembered for the geocentric organization 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 watt motion of the heavenly bodies . further , the planets severally moved in a circle as they orbit the earth - the epicycle . The epicycle would manage the planets to move farther or snuggled to Earth depending on which phase of the epicycle the planet was onUsing the pattern of the epicycle , Ptolemy was up to(p) to account for the...If you want to get a bounteous essay, prescribe it on our website: Orderessay
