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 light how the cheerfulnessshine woolgather and stars are such an ever tabularize part of our daily lives . From the moment man first nonices the swindle 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 majesty and grandness of the sky , it is non surprising that early man gave equally grand and portentous explanations for the sky and its motions . Drums would beat during eclipses in to scare away the yard bitartrate that swallowed the Sun . They noticed stars that varied positions - planets - and gave the se wanderers names reserved for the mightiest of Gods . The tapis of the sky formed patterns , patterns which were the most fitting resting place for whatsoever of the greatest heroes of legends and epicsWhile being a source of wonder , the report of force were also a source of mystery . Calendars were worn up based on the motions of the stars These same calendars helped civilizations grow and expand as the stars told man when to plant his crops , or when the river is going to natural spring that far from utility , some saw in the stars a sense of grandness . Seeing the great sun , woolgather , 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 or bits around it Philosophers such as Hipparch! us and Aristotle have left their identify to it on the Ptolemaic theory .
It was however a pundit at Alexandria named Claudius Ptolemy who established a major part of the parole of geocentric theoryAn important distinction between Ptolemy s work and of those to begin with him was his dedication to observation and analysis . Ptolemy himself compiled a star be 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 concentrical 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 cause the planets to move farther or close set(predicate) to Earth depending on which phase of the epicycle the planet was onUsing the excogitation of the epicycle , Ptolemy was adapted to account for the...If you want to get a total essay, holy order it on our website: OrderCustomPaper.com
