Prof. Fred L. Wilson Rochester Institute of Technology Teaching at RIT HISTORY OF SCIENCE 17. Galileo and the Rise of Mechanism Scientific Method If science has a beginning date, it must be 1632 when the Italian astronomer and physicist, Galileo Galilei, published his book, Dialogue on the Two Systems of the World Note 1 ] All the previous work, all the observations, theory, and fighting against dogmatic concepts were brought together by Galileo. The Greeks, by and large, had been satisfied to accept the "obvious" facts of nature as starting points for their reasoning. Aristotle was quite content to use reason to argue that the heavier stone would fall faster than the lighter stone because it "wanted" to be in its proper place more than the lighter stone. Given his organic reasoning, it would not have occurred to him to test the "obvious." To the Greeks, experimentation seemed irrelevant. It interfered with and detracted from the beauty of pure deduction. Besides, if an experiment disagreed with a deduction, could one be certain that the experiment was correct? Was it likely that the imperfect world of reality would agree completely with the perfect world of abstract ideas; and if it did not, ought one to adjust the perfect to the demands of the imperfect? To test a perfect theory with imperfect instruments did not impress the Greek philosophers as a valid way to gain knowledge. Experimentation began to become philosophically respectable in Europe with the support of such philosophers as the English Scholar Roger Bacon (c. 1220 - c. 1292, a contemporary of

Galileo Galilei Born: 15 Feb 1564 in Pisa (now in Italy) Died: 8 Jan 1642 in Arcetri (near Florence) (now in Italy) Galileo Galilei was an Italian natural philosopher, astronomer, and mathematician who made fundamental contributions to the sciences of motion, astronomy, and strength of materials and to the development of the scientific method. His formulation of (circular) inertia, the law of falling bodies, and parabolic trajectories marked the beginning of a fundamental change in the study of motion. His insistence that the book of nature was written in the language of mathematics changed natural philosophy from a verbal, qualitative account to a mathematical one in which experimentation became a recognized method for discovering the facts of nature. Finally, his discoveries with the telescope revolutionized astronomy and paved the way for the acceptance of the Copernican heliocentric system, but his advocacy of that system eventually resulted in an Inquisition process against him. Early life and career Galileo was born in Pisa, Tuscany, on February 15, 1564, the oldest son of Vincenzo Galilei, a musician who made important contributions to the theory and practice of music and who may have performed some experiments with Galileo in 1588-89 on the relationship between pitch and the tension of strings.

Galileo Galilei (1564 - 1642) Galileo was born near Pisa, where his father Vincenzo Galilei was a musician. Vincenzo was also a highly original thinker, and conducted experiments with stringed instruments to devise a new system of harmony in music, over-throwing the music handed down from the Greeks. Galileo had a mixed education, starting at a monastery school in Vallombrosa where he entered the order as a novice, against the wishes of his father. Vincenzo removed him to Florence, but due to an unsuccessful application to Pisa University, Galileo resumed his studies with the monks. In 1581 Galileo joined the University of Pisa to study medicine. However, his interest in medicine was not great and he was instead attracted to mathematics. He received private instruction in maths from a friend of his father, Ostilio Ricci, and progressed rapidly. Galileo left the University in 1585 without a degree and returned to Florence to study the Greek giants of maths, Archimedes and Euclid. He supported himself by teaching maths in Florence and Siena until 1589 when he became professor of mathematics at Pisa. This allowed Galileo to set himself up in opposition to the professor of physics who taught the science of Aristotle.

Although his father was a musician and wool trader, he wanted his clearly talented son to study medicine as there was more money in medicine. So, at age eleven, Galileo was sent off to study in a Jesuit monastery. After four years, Galileo had decided on his life's work: he announced to his father that he wanted to be a monk. This was not exactly what father had in mind for his gifted son, so Galileo was hastily withdrawn from the monastery. In 1581, at the age of 17, he entered the University of Pisa to study medicine, as his father wished. Shortly thereafter, at age 20, Galileo noticed a lamp swinging overhead while he was in a cathedral. Curious to find out how long it took the lamp to swing back and forth, he used his pulse to time large and small swings. Galileo discovered something that no one else had ever realized: the period of each swing was exactly the same. The law of the pendulum, which would eventually be used to

See Online Courses Search Inventors Galileo Galilei - Biography Galileo Galilei Part One Early Biography The Telescope In Venice on a holiday in 1609, Galileo Galilei heard rumors that a Dutch spectacle-maker had invented a device that made distant objects seem near at hand (at first called the spyglass and later renamed the telescope). A patent had been requested, but not yet granted, and the methods were being kept secret, since it was obviously of tremendous military value for Holland. Such an instrument as the telescope would also be valuable to Venice, and the scientist was determined to attempt to construct his own spyglass. After a frantic 24 hours of experimentation, working only on instinct and bits of rumors, never having actually *seen* the Dutch spyglass, he built a 3-power telescope. After some refinement, he brought a 10-power telescope to Venice and demonstrated it to a highly impressed Senate. His salary was promptly raised, and he was honored with proclamations. If he had stopped here, and become a man of wealth and leisure, he might be a mere footnote in history. Instead, a revolution started when, one fall evening, the scientist trained his telescope on an object in the sky that all people "knew" must be a perfect, smooth, polished heavenly bodythe Moon. We can only imagine his astonishment on finding a surface that was "uneven, rough, full of cavities and prominences." A surface full of features much like those that could be found on Earth. This was tremendously exciting news, although there were still plenty of people who insisted that Galileo

We know that he faced the Inquisition for publishing and defending that idea. We know that, in the face of opposition from the Church that he loved and the Pope Urban who had been his friend, Galileo recanted his findings. But, why did he recant? Who was this Galileo Galilei, this inventor, scientist, mathematician. . . .this man? The purpose of this online curriculum is to discover Galileo Galilei.

Galileo Galilei was the oldest of seven children born to Vincenzo Galilei and Giulia Ammanati. He entered the University of Pisa in 1581 to study medicine. Soon he realized that his interests were not in medicine, but mathematics. After only a year in the university, he made his famous discovery of the isochronal movement of pendulums. He then continued an independent study of science and mathematics while trying to convince his father to allow him to study science and math. In 1586 Galileo withdrew from the University of Pisa without a degree and headed back to live with his family. For the next few years he continued his study of science and gave a series of lectures on the Inferno of Dante's The Divine Comedy at the Florentine Academy. Galileo had many influential friends who were able to help him gain an appointment as a lecturer of mathematics at the University of Pisa in 1859 and then as the chair of mathematics at the University of Padua in 1592.

Maritain Galileo Galileo segnalibri esposizione giudizio testi esposizione esposizione vita Galileo è considerato uno dei fondatori della scienza moderna. A lui infatti si attribuisce la prima sistematica formulazione del metodo scientifico, che poi sarebbe stato universalmente seguito, ossia il metodo di applicare la matematica al dato osservabile. Nato a Pisa, il 15 febbraio 1564, ebbe un temperamento ironico e battagliero. Abbandonò gli iniziali studi di medicina, a cui il padre lo voleva destinare (1581) e che trovò essere condotti sulla base di testi di autorità piuttosto che sull'osservazione. Si volse agli studi di matematica (sotto Ostilio Ricci, discepolo di Tartaglia, uno dei più grandi matematici moderni), che includevano anche la physica , alla scuola di Francesco Buonamici, che criticava sì le tesi aristoteliche sul moto, come impetus non naturale, ma sempre a partire da un metodo scolastico. A tale impostazione scolastica Galileo preferiva il rigore della matematica (seguendo il principio "ut dicenda semper ex dictis pendeant"), osservando con la sua ironia come non sia detto che chi ha inventato la logica l'abbia poi anche saputa applicare: veri logici per lui sono i matematici, non i filosofi (

the Laws of Dynamics Galileo Galilei (1564-1642) was a pivotal figure in the development of modern astronomy, both because of his contributions directly to astronomy, and because of his work in physics and its relation to astronomy. He provided the crucial observations that proved the Copernican hypothesis, and also laid the foundations for a correct understanding of how objects moved on the surface of the earth (dynamics) and of gravity. Newton , who was born the same year that Galileo died, would build on Galileo's ideas to demonstrate that the laws of motion in the heavens and the laws of motion on the earth were one and the same. Thus, Galileo began and Newton completed a synthesis of astronomy and physics in which the former was recognized as but a particular example of the latter, and that would banish the notions of Aristotle almost completely from both. One could, with considerable justification, view Galileo as the father both of modern astronomy and of modern physics. The Telescope Galileo did not invent the telescope ( Dutch spectacle makers receive that credit), but he was the first to use the telescope to study the heavens systematically. His

Galileu i les qualitats En un text del desembre de 1612 on fa unes reflexions Sobre les taques solars , Galileu planteja el seu distanciament de la manera d'explicar dels aristotèlics i proposa un canvi revolucionari. Amb ell, la realitat comença a distanciar-se del que ens ensenyen els sentits. Podem tractar, especulant, de penetrar l' essència vertadera i intrínseca de les substàncies naturals, o també acontentar-nos amb el coneixement d'algunes de les seves propietats (affezioni). Sostinc que tractar d'arribar a l'essència és empresa impossible i vana fatiga tant pel que fa a les substàncies elementals més properes, com a les més remotes i celestials. Sóc igualment ignorant, em sembla, a propòsit de la substància de la terra, com sobre la de la Lluna, els núvols o les taques solars. I no veig que tinguem cap avantatge per comprendre les substàncies pròximes, a part del nombre de casos particulars, encara tots igualment desconeguts. Errem entre ell, i passem d'un a l'altre amb molt poc o cap profit. Si pregunto jo quina és la substància dels núvols i em responen que un vapor humit, desitjaré saber què és el vapor. Potser se'm digui que és aigua, que atenuada pel calor, es resol en vapor. Igualment encuriosit per saber què és l'aigua, tractaré llavors d'esbrinar-ho, i sabré per fi que és aquest cos fluid que corre pels nostres rius i que constantment tractem i manipulem. Però aquest coneixement de l'aigua no és més pregon que el que posseïa inicialment dels núvols, tan sols és més proper, i depèn dels meus sentits. Del mateix mode, no sé més, a propòsit de la vertadera essència del foc o de la terra, que de les del Sol o de la Lluna. Aquest coneixement se'ns concedirà en l'estat de beatitud, i no abans.
