( 1564-1642 )
Galileo Galilei was born near Pisa, Italy, on February 15, 1564 ( Drake ) . Galileo was the first kid of Vincezio Galiei, a merchandiser and a instrumentalist ( Jaki 289 ) . In 1574, Galileo? s household moved from Pisa to Florence, where Galileo started his formal instruction ( Jaki 289 ) . Seven old ages latter, in 1581, Galileo entered the University of Pisa as a medical pupil ( Drake ) . In 1583, place on holiday from medical school, Galileo began to analyze mathematics and physical scientific disciplines ( Jaki 289 ) . A Family friend and professor at the Academy of Design, Ostilio Ricci, worked on interpreting some of Archimedes, which Galileo read and became interested in. This is where Galileo got his deep involvement in Archimedes ( Jaki 289 ) . When returning to medical school, medical school became less appealing to Galileo, and his deep involvements in Archimedes and mathematics drew him in, Galileo left without a grade in 1584 ( Drake ) . Get downing his surveies, in 1585, in Aristotelean natural philosophies and cosmology, Galileo had to go forth the University of Pisa before he got his grade, because of fiscal jobs ( Jaki 289 ) .
Traveling back to Florence, Galileo spent three unsuccessful old ages looking for a teaching place ( Jaki 289 ) . During this clip Galileo was increasing his apprehension of natural philosophies and mathematics. Besides during this difficult clip Galileo wrote two discourses one about rules of reconciliation and the other about centre of gravitation of different solid objects ( Jaki 289 ) . These Hagiographas were circulated in manuscript signifier merely, but they made Galileo good known in the scientific community. Galileo became renowned in 1588, when he gave a talk at the Florentine Academy on the topography of Dante? s Inferno, where he showed his extended cognition on mathematics and geometry ( Jaki 289 ) .
In 1589, Galileo? s lifting repute as a mathematician and natural philosopher ( physicist ) , earned him a instruction topographic point at the University of Pisa ( Jaki 289 ) . Galileo spent three old ages at the University of Pisa. This move changed his constructs of natural philosophies in two ways. The first manner was when he was at the university he was exposed to the Hagiographas of Fiovanni Battista Benedetti, which got his thoughts from fourteenth century scientist Jean Buridan and Nicole Oresme at the University of Paris ( Jaki 289 ) . These composing made him interrupt away from Aristotelean natural philosophies and get down his ain path through physical theories. The 2nd portion was when Galileo started learning he argued and hated the fact that instructors had to have on academic robes while learning. He would accept have oning ordinary apparels, but he instead that it would be the best to be naked ( Jaki 289 ) .
In 1591, Galileo? s male parent died and he had the load to take attention of his female parent, brothers, and sisters ( Jaki 289 ) . Looking for a better place to back up his household, Galileo found one in the University of Padua, portion of the Venetian Republic ( Jaki 289 ) . There harmonizing to him he spent the happiest eighteen-years of his life ( Jaki 289 ) . ? He frequently visited Venice and made many influential friend, among them Giovanfrancesco Sagredo, whom he subsequently immortalized in the Dialogue as the representative of judiciousness and good sense? ( Jaki 289 ) .
In 1604, Galileo publically declared that he was a truster of the celebrated uranologist Copernicus ( Jaki 290 ) . ? In three public talks given in Venice, before an overflow audience, he argued that the new star which appeared earlier that twelvemonth was major grounds in support of the philosophy of Copernicus. ( Actually the new star simply proved that there was something earnestly incorrect with the Aristotelean philosophy of the celestial spheres ) ? ( Jaki 290 ) . ? More of import was the missive Galileo wrote that twelvemonth to Father Paolo Sarpi, in which he stated that? the distance covered in natural gesture are relative to the squares of clip intervals, and at that place forward, the distances covered in equal clip are as
the uneven Numberss get downing from one? ( Jaki 290 ) . What he proposed was the jurisprudence of free autumn, subsequently written as s = ? ( gt2 ) , where s is the distance, t is clip, and g is the acceleration due to gravitation at sea degree ( Jaki 290 ) .
In 1606, he published a little brochure, The Operations of the Geometrical and Military Compass ( Jaki 290 ) . He defended that he travel to University of Padua and said it was because of personal grounds ( Jaki 290 ) . In 1609, a Dutch spectacle shaper, Hans Lippershey, combined two lenses and made a refracting telescope ( Evans ) . Galileo reading about Hans Lippershey find made a telescope, which became the first telescope for astronomical intents ( Evans ) . He submitted the innovation to the Venetian Senate and the telescope was a success. This innovation secured him a life long contract at the University of Padua ( Jaki 290 ) .
With the new innovation of the telescope Galileo was able to see 40x ( Jaki 290 ) . This enables Galileo to detect the mountains on the Moon and the Moons of Jupiter. For four twelvemonth Galileo observed the planets, Moons and stars, and he published his work in a book called Sidereus nuncios ( Jaki 290 ) . During this clip Galileo was really selfish when he was printing his work. Galileo wanted to be the exclusive subscriber to modern natural philosophies and uranology. Dedicated in his work he left behind his common-law married woman, Marina Gamba, and his immature boy, Vincenzio, and placed his two girls in the convent of S. Matteo in Arcetri. Traveling back to Florence he published Discourse on Bodies in Water, which told about the find stages of Venus and the most of import fact it proved Copernican theory ( Jaki 290 ) .
In 1616, as a consequence of turn outing Copernicus? theory the church got huffy at Galileo and called him before the Inquisition ( Jaki 290 ) . The Inquisition pardoned Galileo because Galileo was a loyal Catholic who remained loyal throughout this full ordeal. The Cardinal who help Galileo though the ordeal latter became Pope Urban VIII ( Jaki 290 ) .
Galileo spent the following six old ages composing the book Dialogue refering the Two Chief World Systems ( Jaki 291 ) . It had four parts to it associating to the Earth and the Moon. The first portion was the existence is non perfect like the surface of the Moon is unsmooth. Second, was account of heavenly phenomena. Third, was the argument of the Earth traveling around the Sun and was explained by the moving of the stars and that the Earth moved in two manner and it didn? T affect the Earth. And Forth, the tides prove the Earths two ways of gesture ( Jaki 291 ) .
In 1632, the Dialogue caused Galileo to be brought before Inquisition for the 2nd clip because of his belief and instruction of Copernicus? philosophy ( Jaki 291 ) . This clip the Inquisition didn? t have the understanding for Galileo as they had the last clip. Falsely turn outing his theories were incorrect, the Inquisition forced him to return what he said or non merely he but besides his household will be harmed. Submiting to the Inquisition Galileo was let travel. While go forthing the room his said? Eppursi muove ( And yet it does travel ) ? ( Jaki 291 ) .
Galileo went back to his chair at the University of Padua. There his did work that did conflict with the church philosophies, largely covering with natural philosophies non cosmology ( Jaki 292 ) . The published his work a book similar Two New Sciences. It had four parts to it. First, were the mechanical opposition of metals and the atomic fundamental law of affair. Second, was the belongingss of lever is mathematics. Third and Forth, was the analysis of projectile gesture. Galileo spent his last old ages partly blind and died on January 8, 1642 ( Jaki 292 ) .
