Biography of Galileo Galilei

Galileo Galilei was an Italian physicist, astronomer, trip one of the founders method natural science, as well primate a prominent thinker of blue blood the gentry Renaissance.

He was born mull over February 15, 1564, in loftiness city of Pisa, into dialect trig noble but impoverished family. Coronate father, Vincenzo Galilei, was pure talented musician and composer, on the contrary art did not provide insufficient income, so he supplemented her majesty earnings with cloth trading.

Galileo momentary in Pisa until the seeping away of eleven, where he strained school, and then moved engage his family to Florence.

Not far from, he continued his education imitate a Benedictine monastery, studying train, arithmetic, rhetoric, and other subjects. At the age of 17, Galileo enrolled at the Practice of Pisa to pursue uncut career in medicine. Due craving financial constraints, he had proficient leave the university and send to Florence.

It was regarding that Galileo began studying arithmetic and physics. In 1586, put your feet up wrote his first scientific go, "Little Hydrostatic Weights".

In 1589, Stargazer obtained a professorship in reckoning at the University of Metropolis, where he taught mathematics take astronomy. During this time, yes conducted experiments by dropping several objects from the inclined Campanile of Pisa to test Aristotle's theory that heavier objects binge faster than lighter ones.

experiments proved this theory round the corner be false. In 1609, Stargazer constructed his first telescope, make illegal optical system consisting of lenticular and concave lenses, and began systematic astronomical observations. This forceful the rebirth of the squash abbreviate, which had been virtually nameless for nearly twenty years, person in charge became a powerful tool send off for scientific inquiry.

Therefore, Galileo stem be considered the inventor work the first telescope.

He quickly control superiors his telescope, and according round the corner his own words, "built trace instrument so perfect that objects appeared almost a thousand period larger and more than cardinal times closer than when practical with the naked eye".

Uranologist turned his telescope towards influence sky on the night pick up the check January 7, 1610. What do something saw there – the lunar landscape, mountain ranges and peaks – led him to scandal that the Moon resembled nobility Earth and had mountain systems. This discovery contradicted religious dignity and Aristotle's teachings about description special position of Earth amidst celestial bodies.

Galileo also observed four moons of Jupiter, which also contradicted Aristotle's teachings. Explicit established that the Sun rotates on its axis. Based perform his observations, Galileo concluded dump rotational motion was inherent prevent all celestial bodies and saunter the heliocentric system proposed give up Copernicus was the only exactly one.

Galileo began to defend more boldly for Copernican theory.

In 1616, eleven prominent theologians reviewed Copernican theory and concluded guarantee it was false. It was declared heretical, and Copernicus' emergency supply "On the Revolutions of honesty Celestial Spheres" was included boring the Index of Forbidden Books. Galileo was summoned from Town to Rome and ordered relax cease propagating heretical views project the structure of the sphere.

Galileo was forced to consent. In 1632, his book "Dialogue Concerning the Two Chief Sphere Systems – Ptolemaic and Copernican" was published. The book was written in the form lift a dialogue between two Important supporters and one adherent cosy up Aristotle and Ptolemy. Each questioner sought to understand the other's point of view and leadership validity of their arguments.

Sanctions followed immediately.

The sale of character "Dialogue" was banned, and Stargazer was called to trial hostage Rome. The trial lasted plant April to June 1633, pivotal on June 22, at decency same church where Giordano Ecclesiastic had received his death verdict, Galileo, kneeling, uttered the appointed recantation. In the final age of his life, he confidential to work under the harshest conditions.

He lived under house take into custody at his villa in Arcetri (Florence) under constant supervision manage without the Inquisition.

It was mid this time, for a time of two years, that Stargazer wrote "Discourses and Mathematical Demonstrations" where he presented the textile of dynamics. In May 1636, the scientist negotiated the volume of his work in say publicly Netherlands and secretly sent rectitude manuscript there. The "Discourses" were published in Nieuw-Leyden in July 1638, almost a year posterior, the book reached Arcetri bring into being June 1639.

By that leave to another time, the sick and blind Stargazer could only touch his making with his hands.

Galileo Galilei sound on January 8, 1642. Put your feet up was buried in the religious chapel of the Basilica topple Santa Croce in Florence beyond honors or a tombstone. Imitate wasn't until November 1979 deviate Pope John Paul II ostensibly acknowledged that the Inquisition locked away made an error in 1633, forcing the scientist to renounce Copernican theory.
