Galileo Galilei (Pisa, 15 febbraio 1564 - Firenze, 8 gennaio 1642) è stato uno dei più grandi scienziati italiani.
Galileo, pur costretto per motivi economici a impartire lezioni private, cerca di farsi conoscere nel mondo accademico diffondendo, privatamente, i suoi scritti e partecipando attivamente alla vita culturale del suo tempo con lezioni e conferenze pubbliche.
Da ragazzo, a Pisa, mentre serviva messa, Galileo notò che le oscillazioni del lampadario della cattedrale seguivano una legge periodica, intuendone così l'isocronismo: da qui l'idea di costruire il suo primo strumento: il pendolo.

Galileo was born in Pisa, Italy, the son of Vincenzo Galilei, a mathematician and musician.
Galileo was defended on the spot by a Benedictine abbot, Benedetto Castelli, who was also a professor of mathematics and a former student of Galileo's.
Galileo was never convicted of heresy; even in the second trial, he was only 'vehemently suspected of heresy.' Instead, he was punished at the second trial for having disobeyed what was believed to be a valid injunction not to discuss Copernicanism.

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.
Galileo seems, says von Gebler, to have treated the decree of the Inquisition pretty coolly, speaking with satisfaction of the trifling changes prescribed in the work of Copernicus.

 Galileo: The Telescope & 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.
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.
Perhaps Galileo's greatest contribution to physics was his formulation of the concept of inertia: an object in a state of motion possesses an ``inertia'' that causes it to remain in that state of motion unless an external force acts on it.

Galileo soon became known through his invention of a hydrostatic balance and his treatise on the center of gravity of solid bodies.
He found that bodies do not fall with velocities proportional to their weights, but he did not arrive at the correct conclusion (that the velocity is proportional to time and independent of both weight and density) until perhaps 20 years later.
However, Galileo did find that the path of a projectile is a parabola, and he is credited with conclusions foreshadowing Newton’s laws of motion.

 Galileo Biography
Galileo Galilei was born in 1564 at Pisa.
As a result of inspecting Galileo's letter, in February 1616, it was agreed by the Inquisition that 1) the immobility of the Sun at the centre of the universe was absurd in philosophy and formally heretical, and that 2) the mobility of Earth was absurd in philosophy and at least erroneous in theology.
In defence, Galileo secured from Bellarmino a letter stating that this was not the case but that he had had been notified of the Papal decision to censor Copernicus' De Revolutionibus because a heliostatic claim was contrary to the literal meaning of Scripture.

 Galileo to Jupiter
Galileo spent the first three years of its journey making flybys of Venus and Earth before it was ready to swing outward toward Jupiter.
These gravity-assist encounters provided Galileo with the opportunity to conduct brief scientific observations of Venus, at closest approach on February 10, 1990, and of Earth and the Moon, with closest approaches on December 8, 1990 and December 8, 1992.
In July 1994 Galileo was the only observer to obtain images of the far side of Jupiter when more than 20 fragments of Comet Shoemaker-Levy 9 plunged into Jupiter's nightside atmosphere over a six-day interval.

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.
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.
Galileo needed the money to support his siblings, his mistress (a 21 year old with a reputation as a woman of easy habits), and his three children (two daughters and a boy).

Galileo wrote to his friend Paolo Sarpi, a fine mathematician who was consultor to the Venetian government, in 1604 and it is clear from his letter that by this time he had realised his mistake.
Galileo first turned his telescope on Saturn on 25 July 1610 and it appeared as three bodies (his telescope was not good enough to show the rings but made them appear as lobes on either side of the planet).
Galileo's theory of the tides was entirely false despite being postulated after Kepler had already put forward the correct explanation.

Galileo used his mathematics knowledge and technical skills to improve upon the spyglass and build a telescope.
After Galileo began publishing papers about his astronomy discoveries and his belief in a heliocentric, or Sun-centered, Universe, he was called to Rome to answer charges brought against him by the Inquisition (the legal body of the Catholic Church).
Galileo was cleared of charges of heresy, but was told that he should no longer publicly state his belief that Earth moved around the Sun.

Galileo (Galilei), astronomer, mathematician, and physicist was another of those great anti-Aristotelian scientists of the age, such as Johann Kepler (1571-1630) who also published laws of planetary motion.
He found experimentally that bodies do not fall with velocities proportional to their weights, a conclusion received with hostility because it contradicted the accepted teaching of Aristotle.
Galileo discovered that the path of a projectile is a parabola, and he is credited with anticipating Isaac Newton's laws of motion.

Template:Infobox Biography Galileo Galilei (Pisa, February 15, 1564 – Arcetri, January 8, 1642), was a Tuscan astronomer, philosopher, astrologer, and physicist who is closely associated with the scientific revolution.
In addition, his conflict with the Roman Catholic Church is taken as a major early example of the conflict of religion and freedom of thought, particularly with science, in Western society.
Galileo was a devout Catholic, yet his writings on Copernican heliocentrism disturbed some in the Catholic Church, who believed in a geocentric model of the solar system.

 ESA - Navigation - What is Galileo?   (Site not responding. Last check: 2007-10-22)
The fully deployed Galileo system consists of 30 satellites (27 operational + 3 active spares), positioned in three circular Medium Earth Orbit (MEO) planes in 23616 km altitude above the Earth, and at an inclination of the orbital planes of 56 degrees with reference to the equatorial plane.
Once this is achieved, the Galileo navigation signals will provide a good coverage even at latitudes up to 75 degrees north, which corresponds to the North Cape, and beyond.
Two Galileo Control Centres (GCC) will be implemented on European ground to provide for the control of the satellites and to perform the navigation mission management.

Galileo is presented from the time of his first findings with which Mother Church took offense until twenty years after his recantation.
Galileo himself, historically accurate or not, is a convincing character, and his family, friends, and supporters are also very well-drawn (with the arguable exception of his daughter, who never seems to really flesh out and become a believable human being; her actions and reactions are predictable and wooden).
Whatever the message underlying, and whether the reader agrees with it or not, Galileo is first and foremost a decent piece of drama.
