Galileo Essay, Research Paper


Galileo was a innovator of modern natural philosophies and telescopic uranology who was born on February 15, 1564 near Pisa, Italy. As an Italian physicist and uranologist, he was the first to utilize the telescope to detect many undiscovered kingdoms of infinite. His finds of maculas, lunar mountains and vales, and the orbiters of Jupiter formed the footing of modern uranology. His finds opened a gateway into the undiscovered countries of the existence.

Galileo & # 8217 ; s instruction began in Vallambrosa where monastics taught him, but the takeoff point of his calling was when he registered at the University of Pisa at the age of 17. He learned of the surveies of Aristotle and studied his Hagiographas on logic, gesture, and the construction of the existence. Over the old ages Galileo criticized and refuted many of Aristotle & # 8217 ; s positions. He became one of the most grim advocators against of Aristotle & # 8217 ; s philosophies.

Galileo & # 8217 ; s surveies began in the Cathedral of Pisa one twenty-four hours as Galileo was watching a lamp that was singing from the ceiling. He observed a beat in the swings of the lamp and noticed that the lamp ever took the same clip to travel from one terminal of its swing to the other. His end was to happen out whether or non all of the swings took the same sum of clip. He and a friend both made pendulums and decided to number the figure of oscillations that the pendulums made in a given sum of clip. They found that both pendulums made the same figure of oscillations at the same clip. Therefore he discovered the jurisprudence of isochronism, or equality of clip, of oscillations. By 1586, Galileo left the University of Pisa and went back to his household in Florence.

In Florence, Galileo applied himself to geometry and from the survey of Euclid he shortly passed to that of other ancient mathematicians, particularly Archimedes. Galileo found in Archimedes a instructor for whom he learned the power and the broad rational scope of mathematical logical thinking. Galileo surveies produced two books that he wrote during this period. One, in Latin contains the theorems to find the centre of gravitation of solid organic structures, made him cognize among mathematicians of his clip. The other book, called the Little Balance, was written in Italian. In this book he told how he read the narrative of Archimedes and the surveies of organic structures immersed in H2O.

In the autumn of that twelvemonth Galileo moved to Pisa where he studied while he continued to learn at the university, in this period he resumed his survey of gesture and wrote a short book in Latin know as De Motu ( On Motion ) . In De Motu, Galileo tried to confute some of Aristotle & # 8217 ; s chief positions about gesture. One of his expostulations was the averment that gesture, in the absence of the direct action of a force, is maintained by the medium in which it takes topographic point. De Motu represents Galileo & # 8217 ; s first measure in his systematic survey of gesture and is a cardinal point of mention in Galileo & # 8217 ; s rational development. It shows that Galileo had already started the deep procedure of original thought and critical alteration of Aristotle & # 8217 ; s rules that lasted throughout his life.

At about this clip Galileo tried to confute one peculiar statement of Aristotle & # 8217 ; s. Aristotle said that when organic structures of the same stuff but of different weights autumn freely, they fall with velocities relative to their weights. To turn out that igniter and heavier objects fall at the same velocity, Galileo climbed to the top of the Leaning Tower of Pisa while the full organic structure of pupils gathered in the square below to watch the presentation. From the top of the tower, Galileo let travel two objects of the same substance but of different weights at precisely the same clip. They reached the land at precisely the same clip. This narrative may or may non be true, but was besides proved by the Dutch mathematician Simon Stevinus.

At the age of 28, Galileo moved to Padua. These old ages were said to be the best 18 old ages of his life. Galileo made friends among the Lords and the rich Venetians. One of his most of import friends, Giovanni Francesco Sagredo, used his place to better Galileo & # 8217 ; s position as a scientist at the University. Following Sagredo & # 8217 ; s decease, Galileo & # 8217 ; s friend lived on as a character in two of his best books, Dialogue of the Two Greatest Systems of the World and Two New Sciences. Galileo became a professor at the University of Padua and began to learn big Numberss of pupils. During these old ages Galileo wrote many of his greatest books, including Fortifications, Military Constructions, and Mechanics. The last and most of import was a true technology text edition that described the action of simple machines such as the lever, block, prison guard, and inclined plane. He besides dealt with jobs of falling organic structures that he took up once more in ulterior old ages.

In 1597, Galileo built an instrument that illustrates both his competency in mathematical computation and his great workmanship. This device was known as the geometric and military compass. It was a combination of a splitter and slide regulation. It helped to work out a big figure of mathematical and geometric jobs, including the extraction of square and three-dimensional roots. Because the terminal of the 16th century was a period of struggle, Galileo stressed military utilizations of this instrument. For case, the compass was used to find dealingss of weight and size of cannon

balls, to modulate the forepart and side formations of ground forcess, and to mensurate the disposition of a wall. Galileo sold so many that he could non bring forth adequate to suit the demand. The compass subsequently became one of the most utile and widely used innovations.

On October 9, 1604, a new star appeared in the sky. This new star emerging aroused Galileo & # 8217 ; s scientific wonder and initiated his calling as a lotus-eater. Shortly after the star appeared, Galileo began to do systematic observations He began to mensurate its tallness in the sky and began to look into whether its place in regard to other stars varied from dark to dark. After holding observed it for several hebdomads, he gave three public lectures to depict his findings and drew big crowds. A really of import innovation emerged in 1609. In the early summer he was in Venice when he heard that a certain Fleming had constructed an monocle by which distant objects were seen nearby. Galileo went back to Padua at one time to believe of how he could construct a similar instrument. He concluded that the consequence could be achieved by the combination of a convex and concave glass. Galileo mounted the two lenses at the terminals of a lead tubing, and his first telescope came into being.

At one time he realized the great importance of his instrument, both in scientific discipline and in practical life. He realized it might modify the art of war because it would allow sighting of the enemy at much greater distance that usual. Galileo must hold shown the instrument to his friends or talked about it, for shortly the rumour spread that he had invented it. In a missive to his brother in jurisprudence Galileo stated: & # 8220 ; And intelligence holding reached Venice & # 8230 ; I was called by the Most Serene Signory six yearss ago, to whom it was my responsibility to demo it every bit good as to the whole Senate, to the intense amazement of all. & # 8221 ; Galileo so showed his telescope and it so astonished all.

Once more Galileo showed his workmanship. The first telescope he built had a magnification of three diameters ; the 2nd eight diameters and eventually he built one magnifying 33 diameters. His telescope was a sheet of metal, covered by ruby sateen, of about the length of 24 inches and the diameter of about one and three one-fourth inches in diameter, with two spectacless, one at each terminal. He increased the size of his lenses, halting at the point where a farther addition would ensue in the deformation of images. No instrument but the telescope could give Galileo the feeling of how much the power of the senses could be enlarged. For the first clip he could see distant things every bit good as if they were close by and detect the being of objects that up till so had been excessively far off to be seeable. Many new things in infinite appeared to him.

Galileo shortly discovered four little planets go arounding around the planet Jupiter, as the Moon revolves around the Earth. He named Jupiter & # 8217 ; s satellites the Medicean Satellites and this remained his favourite astronomical find. Less than a month subsequently Galileo announced another item noticed by him. He described the stages of Venus. He said that he began to detect Venus with his instrument and saw it was turning in size daily, maintaining its rotundity until it finally arrived a great distance from the Sun and started to lose its rotundity on its eastern side. A few yearss subsequently, it diminished to a half circle. Then it transformed into a horned form and it became thinner until it vanished. Copernicus had been disappointed non to see the stages of Venus. The fact is that the stages of Venus are undetectable with the bare oculus.

During all of these old ages, the Inquisition had been detecting Galileo. The Inquisition was the high court of the Roman Church. During the Counter Reformation, the Inquisition played a really of import function. Working in secretiveness, it spotted, investigated, and prosecuted those suspected of unorthodoxy, seeking to stamp down it before it could distribute. It exerted censoring to avoid the deformation of the Catholic philosophy, and issued the Index of Prohibited Books. To be tried by the Inquisition was something no 1 could take lightly.

Galileo kept speaking in favour of the Copernican philosophy, and while he busied himself with this, the Inquisition went on analyzing his instance. On February 23 a group of 11 theologists was convened to analyze his beliefs in scientific discipline, or at least what the Inquisition said were his beliefs. The Sun is the centre of the universe and the Earth is non the centre of the universe, or immoveable, but moves harmonizing to the whole itself and besides with diurnal gesture. Neither of these was quoted from his Hagiographas. On the Pope & # 8217 ; s direction, Cardinal Bellarmine called Galileo to his castle and told Galileo that he was non to keep, learn, or support the condemned sentiment of Copernicus. A few yearss subsequently De Revolutionibus, which the Pope had accepted, was condemned and prohibited until it is corrected.

In the concluding old ages Galileo completed his book Two New Sciences. Galileo & # 8217 ; s eyes had bothered him for many old ages. He had been kicking of oculus hurting because of long hours of analyzing. He lost sight in his right oculus foremost, so the left. During the last four old ages of his life he was wholly unsighted. In November 1641 a slow febrility seized Galileo and his creaky strivings had become more. This was his last unwellness. He died on January 8, 1642 at about 78 old ages of age.
