Next: Galilean relativity Up: Galileo and Newton Previous: Introduction Galileo Galilei Only rarely humankind is fortunate to witness the birth and flourishing of a mind as keen and fertile as Galileo's. To him we owe our current notions about motion and the concepts of velocity and acceleration. He was the first to use the telescope as an astronomical tool. Galileo was also creative in devising practical machines: he invented the first accurate clock, an efficient water pump, a precision compass and a thermometer. These achievements distinguish him as the preeminent scietist of his time. Galileo's research in the exact sciences banished the last vestiges of Aristotelian ``science'' and replaced it with a framework within which the whole of physics would be constructed. These changes were not achieved without pain: Galileo was judged and condemned by the Inquisition and died while under house arrest after being forced to recant his Copernican beliefs. Underlying all the discoveries made by Galileo there was a modern philosophy of science. He strongly believed, along the Pythagorean tradition, that the universe should be described by mathematics. He also adopted the view, following Ockham's razor (Sect. ), that given various explanations of a phenomenon, the most succinct and economic one was more likely to be the correct one. Still any model must be tested again and again against experiment: no matter how beautifuland economical a theory is, should it fail to describe the data, it is useless except, perhaps, as a lesson.

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

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.

He was my private tutor in mathematics. Oh, forgive me. I have not introduced myself. I am Guidobaldi del Monte. I am a patron of the University of Pisa and have many connections with the University of Padua as well. I took private lessons in mathematics from Galileo when he was making his living doing such lessons. Talk to Guidobaldi about Galileo Explore Galileo Outside of Virtual Renaissance Talk to Guidobaldi about Galileo We would talk many times of his life. His father was Vincenzo Galilei, a gifted musician, composer and mathematician who greatly influenced his young son. Galileo was the oldest of seven children borne to Vincenzo and his wife Giulia Ammannati on February 15, 1564 in Pisa. As a young boy, Galileo loved to paint and often said that if he could have chosen a path to take in life, it would have been as a painter, not a mathematician. He also wished to join the Jesuit order when he was 14 after having attended the Jesuit school at the monastery of Vallombrosa, just outside the city of Florence. His family had moved to Florence when Galileo was ten. But his father had other ideas. since they were not a rich family, his father wanted Galileo to become a cloth merchant. Galileo objected vehemently but eventually chose another career path of his father's choosing, that of medicine. He started studying medicine at the age of 17 at the University of Pisa. It was here that he earned the nickname, "The Wrangler" because of his constant questioning and arguing against anything his professors said that could not be backed up by solid proof. He turned from medicine to mathematics and science. However, he was forced to leave the university in 1585 due to lack of funds. The university offered scholarships to poor students but with Galileo's reputation as a troublemaker, it is doubtful that he was even considered. It is at this time in his life that I met him, as he made a living teaching private mathematics lessons. He was so brilliant, that I intervened on his behalf at the University of Pisa and helped him become a professor of mathematics there.

Der Fall Galileo Galilei Der groesste Physiker unseres Jahrhunderts sagte ueber Aristoteles: "Man kann kaum moderne Atomphysik betreiben, ohne die griechische Naturphilosophie zu kennen. Am Beispiel dieses Zitats zeigt sich, wie die Philosophie des Aristoteles, obwohl sie nach heutigen Erkenntnissen voll Fehler ist, bis ins 20. Jahrhundert heraufwirkt. Ihre Geschlossenheit, ihr harmonisches Bild vom Kosmos, ihre kristallenen Himmelssphaeren, ihre zentrale Lage der Erde im Weltall, ihr Mensch als Mittel- und Hoehepunkt der Schoepfung, all das und noch viel mehr war so attraktiv, dass kleine Ungereimtheiten gerne verziehen wurden. So behauptete Aristoteles, dass Fliegen 8 Beine haetten (ein genauer Blick zeigt, dass es 6 sind) oder dass das Gehirn des Menschen ein blosses Organ zum Kuehlen des Kopfes sei. Aristoteles war jahrhundertelang einer der Lieblingsphilosophen der katholischen Kirche. Der Grund ist leicht verstaendlich, deckte er doch weite Bereiche der Naturwissenschaften ab, die von der Bibel eher spaerlich behandelt werden. Der Mittelpunkt des Kosmos war die Erde. Dies war eine der zentralen Aussagen des Aristoteles, und diese Aussage wurde bis ins 16. Jahrhundert nicht in Zweifel gezogen. 1543 veroeffentlichte der Kanonikus und Bistumsverweser Nikolaus Kopernikus sein an Papst Paul III gerichtetes Hauptwerk "Sechs Buecher ueber die Umdrehungen der Himmelskoerper". Kopernikus konnte keine Beweise im heutigen Sinne vorlegen, daher argumentierte er philosophisch. Fuer Kopernikus lag der Mittelpunkt der Welt in Sonnennaehe. Die Spoetter stellten sich bald ein, und die aristo- telische Physik genuegte ungeprueft allemal, um Kopernikus als laecherlich hinzustellen. Die Kirche akzeptierte Kopernikus' Ideen als "Hypothese", und die Causa wurde rasch ad acta gelegt.

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 Galileo brings the Italian senators to the tower of Basilica of Saint Mark's, his purpose not yet revealed. They tirelessly climb the many white-gray steps to the round roof. Out of one of the square windows, the senators look through Galileo's improved telescope. Ships arriving in Italy's harbor two hours later are seen clearer than ever. The faces of Florence residents are seen smiling, frowning, and picking their nose. Galileo knows by the senators' amazed expressions that he has just done something incredible. And he had. He really had. You cannot teach a man anything. You can only help him find it within himself. Galileo Galilei Born as Galileo Galilei, on February 15, 1564 in Pisa, Italy, Galileo invented even as a child. When he was a child, he used items found around his home and put them together to make small mechanical toys. I think that this influenced his later life, because this was like practice for inventing. All of these toys worked, and he probably learned to keep at it, because he must have made mistakes. Inventing is similar to this, because you have try out many designs before any of your inventions can work. As a 10-year-old, he attended school at Vallembrosa. He got good grades, and as he grew up, his father, Vincenzio Galilei, decided Galileo should become a doctor. Galileo did not want to do this, but did as he was told. In 1581, Galileo entered the University of Pisa. However, his study of medicine was not interesting to him, and his grades were not good. He began to study mathematics instead. Like his father, Galileo liked mathematics, and preferred it to medicine. But because of Galileo's low grades, his father took him out of the university in 1585.

Njegova iznajdba teleskopa naj bi simbolizirala pomen tehnologije za bolj¹e razumevanje narave. Obsodba pred inkvizicijo, simbol boja med togo Cerkvijo in novo znanostjo, ko naj bi izdahnil sloviti "Eppur si muove!", pa ga je naredila za muèenika.

Galileo Galilei Galileo was born at Pisa on February 15, 1564, the son of Vincenzo Galilei, a musician. He received his early education at the monastery of Vallombrosa near Florence, where his family had moved in 1574. In 1581 he entered the University of Pisa to study medicine. While in the Pisa cathedral during his first year at the university, Galileo supposedly observed a lamp swinging and found that the lamp always required the same amount of time to complete an oscillation, no matter how large the range of the swing. Later in life Galileo verified this observation experimentally and suggested that the principle of the pendulum might be applied to the regulation of clocks. Until he supposedly observed the swinging lamp in the cathedral, Galileo had received no instruction in mathematics. Then a geometry lesson he overheard by chance awakened his interest, and he began to study mathematics and science with Ostilio Ricci, a teacher in the Tuscan court. But in 1585, before he had received a degree, he was withdrawn from the university because of lack of funds. Returning to Florence, he lectured at the Florentine academy and in 1586 published an essay describing the hydrostatic balance, the invention of which made his name known throughout Italy. In 1589 a treatise on the centre of gravity in solids won for Galileo the honourable, but not lucrative, post of mathematics lecturer at the University of Pisa. Galileo then began his research into the theory of motion, first disproving the Aristotelian contention that bodies of different weights fall at different speeds. Because of financial difficulties, Galileo, in 1592, applied for and was awarded the chair of mathematics at Padua, where he was to remain for 18 years and perform the bulk of his most outstanding work. At Padua he continued his research on motion and proved theoretically (about 1604) that falling bodies obey what came to be known as the law of uniformly accelerated motion (in such motion a body speeds up or slows down uniformly with time). Galileo also gave the law of parabolic fall (e.g., a ball thrown into the air follows a parabolic path). The legend that he dropped weights from the leaning tower of Pisa apparently has no basis in fact.

Galileo Galilei Astronomer and mathematician, born in Pisa, Italy. He entered Pisa University as a medical student in 1581, and became professor of mathematics at Padua (15921610), where he improved the refracting telescope (1610), and was the first to use it for astronomy. His bold advocacy of the Copernican theory brought severe ecclesiastical censure. He was forced to retract before the Inquisition, and was sentenced to indefinite imprisonment - though the sentence was commuted by the pope, at the request of the Duke of Tuscany. Under house arrest in Florence, he continued his research, though by 1637 he had become totally blind. Among his other discoveries were the law of uniformly accelerated motion towards the Earth, the parabolic path of projectiles, and the law that all bodies have weight. The validity of his scientific work was formally recognized by the Roman Catholic Church in 1993. www.biography.com BACK TO AUTHOR BIOGRAPHIES
