Outline On Galileo Galilei

Outline On Galileo GalileiThesis statement main argument The astronomer Galileo Galilei contributed to the field of astronomy majorly by observant the sky with a telescope he had built, observations which resulted in his discovery of many astronomical phenomena further proving that the macrocosm was not the center of the solar carcass.Statement of finding (scope of the essay) Following a brief biography of Galileo Galilei, this paper will determine the state of the scientific knowledge introductory to Galileos astronomical discoveries, explain what Galileos contribution to astronomy was, and discuss how his findings subsequently changed humanitys conception of the universe.BodyTopic clock judgment of conviction of paragraph 1 Besides being known as a very prestigious astronomer, Galileo Galilei was also known for being an Italian scientist and philosopher.Birth date February 15, 1564 Place of birth Pisa, Italy. (Galileo Biography, 2013)Death date January 8, 1642 Place of death Arcetri, Italy. When he died, he was guile and very ill, and was under house arrest for heresy. (Galileo Biography, 2013)Galileo first started in a monastery school because he wanted to become a monk, but he last left the monastery and attended the University of Pisa to study medicine, like his father wished. However, he never completed his medicine degree and instead found an interest in mathematics and philosophy. (Bellis, 2013 Galileo Galilei, 2013)Galileo taught for three years at the University of Pisa, but transferred to the University of Padua when his three-year contract at Pisa ended. (Bellis, 2013)In 1609, Galileo heard rumours of a spyglass having been framed by a Dutch spectacle-maker. Galilei decided to create his own spyglass, later renamed a telescope, and so fartually made it more powerful than the Dutch spyglass. One night, he pointed his telescope towards the sky and his astronomical discoveries began then. (Bellis, 2013)Topic sentence of paragraph 2 Prior to Galileos astronomical contribution, the Catholic Church and the Bible were the principal sources of explanation for most of the phenomena that occurred on Earth and in space.In that time period, the geocentric model, suggested by Claudius Ptolemy at the beginning of the 2nd century A.D., argued that the Earth was in the center of the solar system and that the new(prenominal) planets and the sunniness revolved near it. This model was widely accepted and encouraged by the Catholic Church. (Moch, 2009 Redd, 2013)However, a more recent model had been brought forward by Nicholaus Copernicus, in 1543. This model was called the Copernican model and declared that the Earth was not in the center of the solar system, but rather that this place was occupied by the Sun and that all the planets, including the Earth, go around around the Sun. (Moch, 2009 Redd, 2013)Galileo Galilei supported the Copernican theory (Galileo Biography, 2013), but this theory was considered against the teachings of the Church. As a result, Copernicus writings were banned by the Church. (Machamer, 2009 Moch, 2009)Topic sentence for paragraph 3 Galileo Galilei made more than one contribution to the field of astronomy by observing the sky with his telescope, but his major discoveries were the first moons of Jupiter and the phases of Venus.His two major discoveries provided verification that the heliocentric model, introduced by Copernicus, was truly the one that was representative of the solar system. (Moch, 2009 Weisstein, 2007)The moons of Jupiter (*the names of those moons will be included in the final essay*) that Galileo observed spurned the geocentric models argument against the Copernican theory. This argument stated that if the Sun was the center of the solar system, Earth would lose its moon because it overspreadd around the Sun Earth could completely keep its moon if it was in the center. However, with the moons of Jupiter (later named the Galilean moons in honour of Galileo) rot ating around Jupiter, the scientist community could only show the fact that a planet could keep moons, even though it was not in the center of the solar system. (Moch, 2009 Galileo Biography, 2013)The phases of Venus further encouraged the heliocentric model. The phases of Venus indicated that Venus must circle the Sun for its phases to be visible from Earth, just like the phases of the moon were. In the geocentric model, Venus would show no phases and would always be a crescent shape because the Sun would not be in the center of its orbit. (Moch, 2009 Galileo Biography, 2013)Topic sentence of paragraph 4 Although Galileos observations and discoveries were not first accepted by the religious community, evidence of Galileos findings started to circulate and the Church was eventually forced to admit that Galileo had been right. (Galileo Biography, 2013 Bellis, 2013)Galileo had already put outed multiple books (*the names and dates will be included in the final essay*) prior to being charged of heresy by the Church and placed under house arrest. (Galileo Biography, 2013 Bellis, 2013)While being under house arrest, Galileo continued to write and publish books (Galileo Biography, 2013 Bellis, 2013), although he was becoming blind from having stared too much at the Sun with his telescope for another of his astronomical discoveries. (Our solar system, 2011)In 1758, the Church was forced to face the truth and lifted the ban on most of the books that supported the Copernican theory and the heliocentric model. In 1835, it abandoned its opposition against this model completely. (Galileo Biography, 2013)In the twentieth century, some popes acknowledged the revolutionary work done by Galileo. In 1992, Pope John Paul II publicly apologized and showed regret on how the vitrine of Galileo had been delt with. (Galileo Biography, 2013 Bellis, 2013)ConclusionRestatement of thesis statement Galileo Galilei significantly contributed to astronomy primarily by observing the sky w ith a telescope, which resulted in his discovery of many astronomical phenomena proving that the Earth was not the center of the solar system.Summary of main points Prior to Galileos findings, the Church believed in the geocentric model, introduced by Claudius Ptolemy. However, Galileos discovery of the moons of Jupiter and the phases of Venus instead supported the heliocentric model, suggested by Nicolaus Copernicus. Galileos contribution took a long time to be recognized, but it allowed for a better understanding of the way the solar system functions.Other discoveries found on the astronomers contribution Galileos use of a telescope to observe the sky also allowed him to observe the Suns dark patches known as sunspots, part of the star befog of the Milky Way, the rings of Saturn that he identified as ears, and the Moons crater-covered surface. (Moch, 2009) There is also recent evidence that Galileo may have discovered Neptune nearly two centuries in advance it was official foun d by satellites and modern telescopes.
