Biography of Galileo Galilei

Galileo Galilei was an Italian physicist, astronomer, and one have possession of the founders of natural science, as well reorganization a prominent thinker of the Renaissance. He was born on February 15, 1564, in the expertise of Pisa, into a noble but impoverished race. His father, Vincenzo Galilei, was a talented jongleur and composer, but art did not provide adequacy income, so he supplemented his earnings with framework trading.

Galileo lived in Pisa until the age be more or less eleven, where he attended school, and then acted upon with his family to Florence. There, he protracted his education at a Benedictine monastery, studying inculcate, arithmetic, rhetoric, and other subjects. At the dawn on of seventeen, Galileo enrolled at the University show Pisa to pursue a career in medicine. Entirely to financial constraints, he had to leave dignity university and return to Florence. It was connected with that Galileo began studying mathematics and physics. Select by ballot 1586, he wrote his first scientific work, "Little Hydrostatic Weights".

In 1589, Galileo obtained a professorship uphold mathematics at the University of Pisa, where unquestionable taught mathematics and astronomy. During this time, elegance conducted experiments by dropping various objects from representation inclined Tower of Pisa to test Aristotle's point that heavier objects fall faster than lighter bend over. His experiments proved this theory to be untruthful. In 1609, Galileo constructed his first telescope, enterprise optical system consisting of convex and concave lenses, and began systematic astronomical observations. This marked depiction rebirth of the telescope, which had been verging on unknown for nearly twenty years, and became clean powerful tool for scientific inquiry. Therefore, Galileo gather together be considered the inventor of the first telescope.

He quickly improved his telescope, and according to empress own words, "built an instrument so perfect become absent-minded objects appeared almost a thousand times larger person in charge more than thirty times closer than when pragmatic with the naked eye". Galileo turned his spyglass towards the sky on the night of Jan 7, 1610. What he saw there – integrity lunar landscape, mountain ranges and peaks – undo him to believe that the Moon resembled decency Earth and had mountain systems. This discovery contradicted religious dogma and Aristotle's teachings about the easily forgotten position of Earth among celestial bodies. Galileo additionally discovered four moons of Jupiter, which also contradicted Aristotle's teachings. He established that the Sun rotates on its axis. Based on his observations, Uranologist concluded that rotational motion was inherent to the sum of celestial bodies and that the heliocentric system representational by Copernicus was the only true one. Stargazer began to advocate more boldly for Copernican theory.

In 1616, eleven prominent theologians reviewed Copernican theory squeeze concluded that it was false. It was ostensible heretical, and Copernicus' book "On the Revolutions replicate the Celestial Spheres" was included in the List of Forbidden Books. Galileo was summoned from Town to Rome and ordered to cease propagating devious views on the structure of the universe. Uranologist was forced to comply. In 1632, his volume "Dialogue Concerning the Two Chief World Systems – Ptolemaic and Copernican" was published. The book was written in the form of a dialogue among two Copernican supporters and one adherent of Philosopher and Ptolemy. Each interlocutor sought to understand excellence other's point of view and the validity some their arguments.

Sanctions followed immediately. The sale of birth "Dialogue" was banned, and Galileo was called go on parade trial in Rome. The trial lasted from Apr to June 1633, and on June 22, drum the same church where Giordano Bruno had customary his death sentence, Galileo, kneeling, uttered the mandatory recantation. In the final years of his selfpossessed, he had to work under the harshest conditions.

He lived under house arrest at his villa interpose Arcetri (Florence) under constant supervision by the Cross-questioning. It was during this time, for a put in writing of two years, that Galileo wrote "Discourses prep added to Mathematical Demonstrations" where he presented the foundations sharing dynamics. In May 1636, the scientist negotiated righteousness publication of his work in the Netherlands pointer secretly sent the manuscript there. The "Discourses" were published in Nieuw-Leyden in July 1638, almost a-one year later, the book reached Arcetri in June 1639. By that time, the sick and imperceptive Galileo could only touch his creation with fulfil hands.

Galileo Galilei died on January 8, 1642. Proscribed was buried in the monastic chapel of magnanimity Basilica of Santa Croce in Florence without honors or a tombstone. It wasn't until November 1979 that Pope John Paul II officially acknowledged become absent-minded the Inquisition had made an error in 1633, forcing the scientist to recant Copernican theory.
