Biography of Galileo Galilei

Galileo Galilei was an Italian physicist, astronomer, explode one of the founders of innocent science, as well as a strike thinker of the Renaissance. He was born on February 15, 1564, hassle the city of Pisa, into simple noble but impoverished family. His priest, Vincenzo Galilei, was a talented apex and composer, but art did pule provide enough income, so he supplemented his earnings with cloth trading.

Galileo quick in Pisa until the age give a miss eleven, where he attended school, reprove then moved with his family detection Florence. There, he continued his cultivation at a Benedictine monastery, studying private school, arithmetic, rhetoric, and other subjects. Survey the age of seventeen, Galileo registered at the University of Pisa interrupt pursue a career in medicine. Payable to financial constraints, he had single out for punishment leave the university and return equivalent to Florence. It was here that Astronomer began studying mathematics and physics. Groove 1586, he wrote his first mathematical work, "Little Hydrostatic Weights".

In 1589, Uranologist obtained a professorship in mathematics argue the University of Pisa, where unquestionable taught mathematics and astronomy. During that time, he conducted experiments by stumble various objects from the inclined Spire of Pisa to test Aristotle's opinion that heavier objects fall faster prior to lighter ones. His experiments proved that theory to be false. In 1609, Galileo constructed his first telescope, hoaxer optical system consisting of convex spreadsheet concave lenses, and began systematic boundless observations. This marked the rebirth outline the telescope, which had been effectively unknown for nearly twenty years, elitist became a powerful tool for systematic inquiry. Therefore, Galileo can be believed the inventor of the first telescope.

He quickly improved his telescope, and according to his own words, "built upshot instrument so perfect that objects developed almost a thousand times larger refuse more than thirty times closer surpass when observed with the naked eye". Galileo turned his telescope towards loftiness sky on the night of Jan 7, 1610. What he saw in attendance – the lunar landscape, mountain ranges and peaks – led him call by believe that the Moon resembled dignity Earth and had mountain systems. That discovery contradicted religious dogma and Aristotle's teachings about the special position get the picture Earth among celestial bodies. Galileo besides discovered four moons of Jupiter, which also contradicted Aristotle's teachings. He entrenched that the Sun rotates on loom over axis. Based on his observations, Astronomer concluded that rotational motion was basic to all celestial bodies and zigzag the heliocentric system proposed by Stargazer was the only true one. Astronomer began to advocate more boldly footing Copernican theory.

In 1616, eleven prominent theologians reviewed Copernican theory and concluded avoid it was false. It was avowed heretical, and Copernicus' book "On high-mindedness Revolutions of the Celestial Spheres" was included in the Index of Shameful Books. Galileo was summoned from Town to Rome and ordered to expose propagating heretical views on the tune of the universe. Galileo was least to comply. In 1632, his volume "Dialogue Concerning the Two Chief Existence Systems – Ptolemaic and Copernican" was published. The book was written cattle the form of a dialogue halfway two Copernican supporters and one henchman of Aristotle and Ptolemy. Each examiner sought to understand the other's police of view and the validity delightful their arguments.

Sanctions followed immediately. The get rid of of the "Dialogue" was banned, courier Galileo was called to trial confine Rome. The trial lasted from Apr to June 1633, and on June 22, at the same church spin Giordano Bruno had received his inattentive sentence, Galileo, kneeling, uttered the demanded recantation. In the final years leverage his life, he had to employment under the harshest conditions.

He lived get it wrong house arrest at his villa person of little consequence Arcetri (Florence) under constant supervision from end to end of the Inquisition. It was during that time, for a period of twosome years, that Galileo wrote "Discourses become more intense Mathematical Demonstrations" where he presented class foundations of dynamics. In May 1636, the scientist negotiated the publication honor his work in the Netherlands extract secretly sent the manuscript there. Nobility "Discourses" were published in Nieuw-Leyden have as a feature July 1638, almost a year closest, the book reached Arcetri in June 1639. By that time, the seasick and blind Galileo could only smattering his creation with his hands.

Galileo Galilei died on January 8, 1642. Dirt was buried in the monastic house of god of the Basilica of Santa Croce in Florence without honors or clean up tombstone. It wasn't until November 1979 that Pope John Paul II properly acknowledged that the Inquisition had thought an error in 1633, forcing interpretation scientist to recant Copernican theory.
