When Galileo Galilei was eight, his family moved to Florence, but he was left under the care of Muzio Tedaldi for two years. When Galileo was ten, he left Pisa to join his family in Florence and there he was under the tutelage of Jacopo Borghini.

The Church at the time of Galileo kept much more closely to reason than did Galileo himself, and she took into consideration the ethical and social consequences of Galileo's teaching too. Her verdict against Galileo was rational and just, and the revision of this verdict can be justified only on the grounds of what is politically opportune.
Sixteen years after his first encounter with the church Galileo published his “Dialogue on the Two World Systems” in 1632, and the pope, Urban VIII, ordered another investigation against him. This time he was prosecuted, following the usual methods of the Roman Inquisition.
Pope John Paul IIGalileo took back his statement, but still lived under house arrest for the rest of his life. It took 359 years and the leadership of Pope John Paul II (left) to recognize the wrong. On October 31, 1992, he formally apologized for the "Galileo Case" in the first of many famous apologies during his papacy.
The troubles developed after Pope Urban VIII gave Galileo permission to write a book discussing the contending views of the universe: his Dialogue Concerning the Two Chief World Systems.
the InquisitionThis brought matters to an impasse. Eventually, Galileo noted that he had probably overstated the mark. On 22 June 1633 the Inquisition declared him to be vehemently suspect of heresy. He formally abjured, and was sentenced to life imprisonment, which was commuted to house arrest.
More recently, Pope John Paul II himself has said that the scientist was "imprudently opposed." "We today know that Galileo was right in adopting the Copernican astronomical theory," Paul Cardinal Poupard, the head of the current investigation, said in an interview published this week.
the Vatican formally and publicly cleared Galileo of any wrongdoing. The Church eventually lifted the ban on Galileo's Dialogue in 1822, when it was common knowledge that the Earth was not the center of the Universe.

In 1520, Leo issued the papal bull Exsurge Domine demanding Luther retract 41 of his 95 theses, and after Luther's refusal, excommunicated him. Some historians believe that Leo never really took Luther's movement or his followers seriously, even until the time of his death in 1521.
In the first session, prosecutor Maculano introduced a warning issued against Galileo 17 years earlier, in which Galileo was ordered by the Church’s Commissary General to abandon his Copernican ideas and not to defend or teach them in any way. This document was significant, since in his book (published in 1632), Galileo presented arguments favoring the Copernicus model, even though he added a preface and a coda which appeared to imply that one couldn’t conclude which of the two models was correct.
From its extremely narrow perspective, the Church did act within its legal authority: Galileo was convicted because of two indisputable facts.
English poet John Milton visiting Galileo when a prisoner of the Inquisition. On June 22, 1633, Galileo was ordered to kneel as he was found “vehemently suspected of heresy.”. He was forced to “abandon completely the false opinion” of Copernicanism, and to read a statement, in which he recanted much of his life’s work.

It even contained false allegations raised against him some 18 years earlier, such as that he had been heard to state that God was an “accident.”.
Then he paid a price. Four centuries ago, the Italian scientist Galileo Galilei put his liberty and life on the line to convince the religious establishment that the Copernican model of the solar system—in which the Earth and the other planets revolved around the sun—represented physical reality. Following his own observations and ...
When asked what instructions he had received in 1616, Galileo said, “Lord Cardinal Bellarmino [who had been Chief Theologian of the Holy Office] told me that since Copernicus’s opinion, taken absolutely was contrary to Holy Scripture, it could neither be held or defended, but it could be taken and used suppositionally.”.
Galileo studied speed and velocity, gravity and free fall, the principle of relativity, inertia, projectile motion and also worked in applied science and technology, describing the properties of pendulums and " hydrostatic balances".
Galileo's 1610 The Starry Messenger ( Sidereus Nuncius) was the first scientific treatise to be published based on observations made through a telescope. It reported his discoveries of: 1 the Galilean moons 2 the roughness of the Moon's surface 3 the existence of a large number of stars invisible to the naked eye, particularly those responsible for the appearance of the Milky Way 4 differences between the appearances of the planets and those of the fixed stars—the former appearing as small discs, while the latter appeared as unmagnified points of light
In the Starry Messenger, Galileo reported that stars appeared as mere blazes of light, essentially unaltered in appearance by the telescope, and contrasted them to planets, which the telescope revealed to be discs. But shortly thereafter, in his Letters on Sunspots, he reported that the telescope revealed the shapes of both stars and planets to be "quite round". From that point forward, he continued to report that telescopes showed the roundness of stars, and that stars seen through the telescope measured a few seconds of arc in diameter. He also devised a method for measuring the apparent size of a star without a telescope. As described in his Dialogue Concerning the Two Chief World Systems, his method was to hang a thin rope in his line of sight to the star and measure the maximum distance from which it would wholly obscure the star. From his measurements of this distance and of the width of the rope, he could calculate the angle subtended by the star at his viewing point.
To him, it seemed, by comparison with his heartbeat, that the chandelier took the same amount of time to swing back and forth, no matter how far it was swinging. When he returned home, he set up two pendulums of equal length and swung one with a large sweep and the other with a small sweep and found that they kept time together. It was not until the work of Christiaan Huygens, almost one hundred years later, that the tautochrone nature of a swinging pendulum was used to create an accurate timepiece. Up to this point, Galileo had deliberately been kept away from mathematics, since a physician earned a higher income than a mathematician. However, after accidentally attending a lecture on geometry, he talked his reluctant father into letting him study mathematics and natural philosophy instead of medicine. He created a thermoscope, a forerunner of the thermometer, and, in 1586, published a small book on the design of a hydrostatic balance he had invented (which first brought him to the attention of the scholarly world). Galileo also studied disegno, a term encompassing fine art, and, in 1588, obtained the position of instructor in the Accademia delle Arti del Disegno in Florence, teaching perspective and chiaroscuro. Being inspired by the artistic tradition of the city and the works of the Renaissance artists, Galileo acquired an aesthetic mentality. While a young teacher at the Accademia, he began a lifelong friendship with the Florentine painter Cigoli.
Because of that region, the adjective galilaios ( Greek Γαλιλαῖος, Latin Galilaeus, Italian Galileo ), which means "Galilean", has been used in antiquity (particularly by emperor Julian) to refer to Christ and his followers. The biblical roots of Galileo's name and surname were to become the subject of a famous pun.
Galileo named the group of four the Medicean stars, in honour of his future patron, Cosimo II de' Medici , Grand Duke of Tuscany, and Cosimo's three brothers. Later astronomers, however, renamed them Galilean satellites in honour of their discoverer.
Three of Galileo's five siblings survived infancy. The youngest, Michelangelo (or Michelagnolo), also became a lutenist and composer who contributed to Galileo's financial burdens for the rest of his life. Michelangelo was unable to contribute his fair share of their father's promised dowries to their brothers-in-law, who would later attempt to seek legal remedies for payments due. Michelangelo would also occasionally have to borrow funds from Galileo to support his musical endeavours and excursions. These financial burdens may have contributed to Galileo's early desire to develop inventions that would bring him additional income.
Galileo was ordered to turn himself in to the Holy Office to begin trial for holding the belief that the Earth revolves around the sun, which was deemed heretical by the Catholic Church. Standard practice demanded that the accused be imprisoned and secluded during the trial.
This was the second time that Galileo was in the hot seat for refusing to accept Church orthodoxy that the Earth was the immovable center of the universe: In 1616, he had been forbidden from holding or defending his beliefs.
Galileo agreed not to teach the heresy anymore and spent the rest of his life under house arrest. It took more than 300 years for the Church to admit that Galileo was right and to clear his name of heresy.
In the 16 33 interrogation, Galileo denied that he “held” belief in the Copernican view but continued to write about the issue and evidence as a means of “discussion” rather than belief.
