• Galileo Galilei.
• Generally called GALILEO. ...
• It is the great merit of Galileo that, happily combining experiment with calculation, he opposed the prevailing system according to which, instead of going directly to nature for investigation of her laws and processes, it was held that these were best learned by authority, especially by that of Aristotle, who was supposed to have spoken the last word upon all such matters, and upon whom many erroneous conclusions had been fathered in the course of time. Against such a superstition Galileo resolutely and vehemently set himself, with the result that he not only soon discredited many beliefs which had hitherto been accepted as indisputable, but aroused a storm of opposition and indignation amongst those whose opinions he discredited; the more so, as he was a fierce controversialist, who, not content with refuting adversaries, was bent upon confounding them. ... As Sir David Brewster (Martyrs of Science) says, "The boldness, may we not say the recklessness, with which Galileo insisted on making proselytes of his enemies, served but to alienate them from the truth. ...
• Although in the popular mind Galileo is remembered chiefly as an astronomer, it was not in this character that he made really substantial contributions to human knowledge -- as is testified by such authorities as Lagrange, Arago, and Delambre -- but rather in the field of mechanics, and especially of dynamics, which science may be said to owe its existence to him. ... Galileo, in consequence of this and other troubles, found it prudent to quit Pisa and betake himself to Florence, the original home of his family. ... Following up his experiments at Pisa with others upon inclined planes, Galileo established the laws of falling bodies as they are still formulated. ...
• Hearing early in 1609 that a Dutch optician, named Lippershey, had produced an instrument by which the apparent size of remote objects was magnified, Galileo at once realized the principle by which such a result could alone be attained, and, after a single night devoted to consideration of the laws of refraction, he succeeded in constructing a telescope which magnified three times, its magnifying power being soon increased to thirty-two. This instrument being provided and turned towards the heavens, the discoveries, which have made Galileo famous, were bound at once to follow, though undoubtedly he was quick to grasp their full significance. ... But with his telescope Galileo found that Venus did actually exhibit the desired phases, and the objection was thus turned into an argument for Copernicanism. Finally, the spots on the sun, which Galileo soon perceived, served to prove the rotation of that luminary, and that it was not incorruptible as had been assumed. ...
• Prior to these discoveries, Galileo had already abandoned the old Ptolemaic astronomy for the Copernican. ... His telescopic discoveries, the significance of which he immediately perceived, induced him at once to lay aside all reserve and come forward as the avowed and strenuous champion of Copernicanism, and, appealing as these discoveries did to the evidence of sensible phenomena, they not only did more than anything else to recommend the new system to general acceptance, but invested Galileo himself with the credit of being the greatest astronomer of his age, if not the greatest who ever lived. ...
• The direct services which Galileo rendered to astronomy are virtually summed up in his telescopic discoveries, which, brilliant and important as they were, contributed little or nothing to the theoretical perfection of the science, and were sure to be made by any careful observer provided with a telescope. ... Since the first and second of his famous laws were already published by Kepler in 1609 and the third, ten years later, it is truly inconceivable, as Delambre says, that Galileo should not once have made any mention of these discoveries, far more difficult than his own, which finally led Newton to determine the general principle which forms the very soul of the celestial mechanism thus established. It is, moreover, undeniable, that the proofs which Galileo adduced in support of the heliocentric system of Copernicus, as against the geocentric of Ptolemy and the ancients, were far from conclusive, and failed to convince such men as Tycho Brahé (who, however, did not live to see the telescope) and Lord Bacon, who to the end remained an unbeliever. Milton also, who visited Galileo in his old age (1638), appears to have suspended his judgment, for there are passages in his great poem which seem to favour both systems. The proof from the phenomenon of the tides, to which Galileo appealed to establish the rotation of the earth on its axis, is now universally recognized as a grave error, and he treated with scorn Kepler's suggestion, foreshadowing Newton's establishment of the true doctrine, that a certain occult influence of the moon was in some way responsible. ...

• During the flybys of Venus and the Earth, Galileo scientists took the opportunity to study these two planets as well as the Moon, making some unprecedented observations as a result. In addition, following each Earth flyby, Galileo made excursions as far out in the solar system as the asteroid belt, enabling scientists to make the first close-up studies of two asteroids, Gaspra and Ida. As is this were not sufficient, Galileo scientists were fortunate to be the only ones with a direct view of the Comet Shoemaker-Levy 9 fragment impacts on Jupiter. ...

• Galileo Galilei .
• Before we start talking about Galileo Galilei, we need to understand a little about the era he lived in, and its view of the Universe. ...
• Galileo Galilei was born in Pisa, Italy on February 15, 1564, 21 years after the death of Copernicus and three days before the death of Michelangelo. ... Although Galileo's father was a musician and wool trader, he wanted his clearly talented son to study medicine as there was more money in medicine (some things don't change, even over 400 years!). 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. ... 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, Galileo 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. ... 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 regulate clocks, made Galileo instantly famous. ...
• Unfortunately, except for mathematics, Galileo was bored by most of his courses and outspoken to his professors. His frequent absences from class eventually led the university to inform Galileo's family that their son was in danger of flunking out. A compromise was worked out, where Galileo would be tutored full-time in mathematics by the mathematician of the Tuscan court. Galileo's father was hardly overjoyed about this turn of events, since a mathematician's earning power was roughly around that of a musician, but it seemed that this might yet allow Galileo to successfully complete his college education. In the end, Galileo left the University of Pisa without a degree--a college dropout. ...
