The paper which I entrust be writing will discuss the life, discoveries, and the modern impact of the scientific accomplishments of Galileo Galilei. Born in Pisa, Italy in 1564, Galileo entered Pisa University as a medical student in 1581 and became a professor of mathematics at Padua. An astronomer and mathematician, Galileo was, unluckily for himself, a man ahead of his season. Galileo discovered the law of uniformly accelerated motion towards the Earth, the parabolic path of rocket salads, and the law that altogether bodies consent weight. Among his some other accomplishments was the improvement of the refracting background in 1610 and his protagonism of the Copernican surmisal which brought him into a conflict of ideas and truths between himself and the Inquisition. He was condemned by the church whose theories threatened everything that was taught by the priesthood as the holy place truth and he was finally broken by the Inquisition. beforehand being ultimately defeated by the church, however, Galileo make umteen contributions to the world of physics. His scientific discoveries and endeavors were barely a portion of his contributions to the scientific community. Galileos methods of testing and proving his theories were too of major importance since these painstaking and strike methodologies would lay the groundwork for future scientific discoveries. His brilliance brought just nigh a new era in scientific growth and his defeat at the hands of the church put a stop to the scientific variation which he had started. In 1993 the Vatican formally recognized the validity of Galileo Galileis scientific work.

COLLEGE MATHEMATICS JOURNAL - May 1994, record 25 Issue 3, p 193 Galileo Galilei was a keen scientist and open in the fields of mechanics, astronomy, thermometry, and magnetism, although mechanics and astronomy were his main passions. He was arguably angiotensin converting enzyme of the brightest men who ever lived. Galileo discovered and deepen more scientific discoveries of his tetradth dimension period and was highly regarded as a Mathematician and Natural Philosopher. Galileo was persecuted for his views on Earths relationship with the rest of the celestial sphere since he retrieved that the Earth revolved around the fair weather and that the welkin were constantly changing and evolving. Since Galileis vision of a metamorphosing universe came in direct conflict with the views of Aristotle, views held by and offered by the church, Galileo was eventually called before the Inquisition and forced to recant his views. N singletheless, Galileo Galilei make noteworthy contributions to the scientific community and he is remembered as a striking scientist and innovator.
Galileo Galilei was born in 1564 in Pisa, Italy (then a part of the duchy of Tuscany), to Vincenzo Galilei, a musician, and Giulia Ammannati. Galileo studied medicine at the university of Pisa from 1581 to 1585, but his historical interests were in mathematics and born(p) philosophy and Galileo left the university in 1585 without a degree. It was during this date frame that Galileo began to doubt conventional science, since more of what he was being taught at that time as scientific fact was conflicting with the evidence which he saw in his hands-on medical reflexions(Hitzeroth, Heerboth, The Importance of Galileo, pp 14-15). Following his period as a student, Galileo time-tested his hand at teaching.
Galileo began privately teaching in Florence and he returned to the university of Pisa to teach mathematics in 1589. Galileo taught at the university of Pisa until 1592 when he was appointed professor of mathematics at Padua (the university of the Republic of Venice.) Galileos duties as a professor of mathematics at Padua were to teach euclidean geometry and standard (geocentric) astronomy to medical students. The medical students at that time were expected to know some astronomy in put together to make social function of astrology in their medical practices. In Padua, he continued his physics research in the domain of a function of mechanics and astronomy.
In the area of mechanics is where Galileos most notable observations were exhibited. The traditional theory accepted by nearly everyone at that time was Aristotles theory that heavier objects, when dropped from the same height as visible radiation ones, will fall at a faster rate. In op couch to this notion, Galileo stated that with the removal of outside influences such as wind resistance, both objects will fall simultaneously at virtually the same speed. Although a very popular business relationship of Galileo states that he attempted to prove this theory by dropping different weights from the campanile (leaning tower) of the Duomo in Pisa, this particular look into was never actually proven to stir occurred. However, a similar experiment had already been made by the Flemish engineer Simon Stevin in 1586. Galileo has s helper that his interest in Aristotles Theory about go objects was aro apply when, during a hailstorm, he noticed that both super and small hailstones hit the ground at the same time. This observation caused Galileo to seriously doubt Aristotles Theory since according to Aristotle, the larger-sized hailstones would have had to have fallen from a oft greater height and at virtually the same time as the lighter hailstones in order for them to reach the ground at the same time (which Galileo arrange very improbable.) Galileo was also very much interest in astronomy. Tycho Brahe, a Danish astronomer, found a supernova in the constellation Cassiopeia in 1572 which promptly disappeared two years later. This stripping challenged Aristotles theory of the heavens as perfect, unchanging, and immutable. This breakthrough, along with another nova coming into court in 1604, also persuaded Galileo to give three public lectures in Padua in his capacity as a professor of mathematics. Galileo used the nova as an excuse to challenge Aristotles views of heavens which were unchanging.
In 1609, Galileo intimate of a spyglass that a Dutchman had sh stimulate in Venice. Using his own technical skills as a mathematician and a workman, along with reports of the gimmick of the device, Galileo made a series of telescopes whose optical performance was much better than that of the Dutch instrument. The first telescope he constructed had a threef gray magnification, which he quickly improved to 32 generation magnification. It was this instrument which Galileo used to develop his galactic discoveries.
The numerous astronomical discoveries made by Galileo with the aid of his telescopes were described in a short adjudge called Message from the stars or Starry messenger (Sidereus Nuncius) published in Venice in May 1610. In this word of honor, Galileo claimed to have seen mountains on the Moon, to have proved that the Milky Way was made up of a myriad of tiny stars, and to have seen four small bodies (moons) orbiting the major planet Jupiter. Galileo named the moons of Jupiter the Medicean stars.
It was after this discovery of the moons of Jupiter that Galileo became the official mathematician and natural philosopher to the Grand Duke of Tuscany. It was also during this time frame that Galileo made many mathematical observations of carnal properties.
Among these observations was the discovery that projectiles follow parabolic paths. This discovery allowed arcs of physical objects to be calculated. Another achievement of Galileo in this time period was the naming of the cycloid curve in 1599.
In 1639, Galileo wrote to Toricelli about the cycloid, saying that he had been studying its properties for forty years. Galileo tested and failed to influence the area of a cycloid by study its area to that of the generating circle. After his failure at trying to find a mathematical method of finding the area of a cycloid, he tried weighing pieces of metal cut into the mannequin of the cycloid. He found that the ratio of the weights was approximately three to one but decided that it was not exactly three.
It was in his use with the Grand Duke of Tuscany in Florence that Galileo first became involved in disputes about Copernicanism. Copernicanism was a theory that was posed by Nicolaus Copernicus on the position of the earth in relation to the heavens. Copernicus had stated in the book On the revolutions of the heavenly spheres (De revolutionibus orbium coelestium, Nuremberg, 1543), that the Sun (not the Earth) is at rest in the center of the universe and that the earth revolves around the sun. This theory , also known as the heliocentric theory, was lent credence in Galileos eyes when, in 1613, he discovered that, when seen through the telescope, the planet Venus showed phases resembling those of the Moon, and therefore Venus must orbit the Sun and not the Earth(Drake, Galileo: Pioneer Scientist, pp. 136 - 137). Galileo went to great lengths to support Copernicanism in the use of his discoveries and observations, he also used his great mathematical skills to aid in proving Copernican theories.
Between 1619 and 1624 Galileo adapted a telescope for the viewing of extremely small objects. This microscope, which he called occhialini was composed of the resistance of a telescope, of reduced size, furnished with two lenses.
Galileo gave his microscopes to various people, including Federigo Cesi.
It was the support of the Copernican theories which brought Galileo into direct conflict with the Inquisition and the Roman Catholic Church. Since Copernicanism was in contradiction with Scripture, Galileo was treading on thin ice with the Inquisition. A young Dominican, Tommaso Caccini, denounced Galileo, his theories, and the Copernican theories officially from the pulpit during a language in the Santa Maria Novella in 1614 (de Santillana, The Crime of Galileo, p. 42). In 1616, Galileo was officially advised by Cardinal Bellarmino on the behalf of the Pope to proceed with caution and to speak only hypothetically about the Copernican theory and not as if the theory were reality. Following this confrontation with the church, Galileo returned to Florence and continued work on his book (Dialogue Concerning theTwo Chief World Systems), as the Pope wished, Galileo gave more focus to mathematical arguments rather than to experimental or physical arguments.
Although Galileo tried to obey the Popes wishes in his wording of the Dialogue, when the book finally appeared in 1632, it raised an immediate storm of protest leading immediately to the arrest of Galileo and a trial by the Inquisition. The inquisition found Galileo guilty of publishing a heretical book and insisted that he denounce his theories and confess his crimes before the church. Although he was lead to believe that this act would cause the Inquisition to be lenient (and would bear them from torturing him to death), Galileo was still sentenced to life imprisonment at his villa in Arcetri near Florence (Reston, Galileo A Life, pp. 253 - 254.) It was during this house arrest that Galileo produced perhaps his superior work, his Discourses on the Two New Sciences , which has been hailed as possibly the al-Qaida of modern physics. This book was smuggled out of Italy to France and was published in Leyden in 1638. In this book, Galileo presented the true laws of accelerated motion and go bodies, as well as the fundamental theory of projectile motion and important applications of mathematics to a multitude of physical problems.
Galileo died totally blind at 77 years old in 1642. Galileo believed that experimentations and observations of these experiments was crucial to the scientific process. (Shapere, Galileo A Philisophical Study, p. 126) Although Galileo was a great scientist, Pope Urban VIII refused to permit Galileos burial with a monument, instead, Galileo was buried unceremoniously in the Church of Santo Croce, in Florence. His remains have since been moved to their present location in a magnificent tomb opposite that of Michelangelo near the entrance to the church. It was only as recently as 1993 that the church has admitted that they were wrong and that Galileos theories were correct.
Galileos curious accomplishments in the fields of mathematics and astronomy upheld and proved the theories of Copernicus whose theories whitethorn have been scoffed at as fantasy. He began the scientific revolution of his time period and his persecution by the church, unfortunately, put an end to the revolution. He was truly a pioneer. Were it not for Galileos courage of his convictions, many scientific discoveries, including those of other scientists of his era, whitethorn never have occurred or may have been delayed considerably. Without the theories, discoveries, and experiments of Galileo Galilei, we may never have made it to the moon, been able to examine viruses or germs under a microscope to be able to defeat them, or been able to write a physical science term paper (on Galileo of course.) If for no other reason than his invention of the microscope, Galileo deserves to be known as one of the greatest scientists the world has ever known.
