Galileo Galilei was born on 15 February near Pisa, the son of a musician. In Italian scientist Galileo Galilei, using his own telescope, modeled on an invention recently made in the Netherlands, discovered that the Moon, far from being smooth and utterly unlike Earth, had mountains and craters.
In the month of March ofGalileo Galilei became seriously ill. It was not until the work of Christiaan Huygensalmost one hundred years later, that the tautochrone nature of a swinging pendulum was used to create an accurate timepiece. Galileo stated his belief in heliocentrism and that many were misunderstanding how it was described in the Scriptures.
Galileo here treated for the first time the bending and breaking of beams and summarized his mathematical and experimental investigations of motion, including the law of falling bodies and the parabolic path of projectiles as a result of the mixing of two motions, constant speed and uniform acceleration.
Barberini was a friend and admirer of Galileo, and had opposed the condemnation of Galileo in Galilei further asserted that the parabola was the theoretically ideal trajectory of a uniformly accelerated projectile in the absence of air resistance or other disturbances.
The Greeks named the stars and plotted their positions. In it he made a point of quoting Acts 1: He discovered the fourth on 13 January. His last book was published inin which he discussed and improved his early studies in the movement and the principles of physics. He was pronounced to be vehemently suspect of heresy and was condemned to life imprisonment and was made to abjure formally.
Despite being a genuinely pious Roman Catholic,  Galileo fathered three children out of wedlock with Marina Gamba. The next time you gaze up at the night sky, you're likely to spot a twinkling star.
Although he was now going blind he continued to write. In August of that year he presented an eight-powered instrument to the Venetian Senate Padua was in the Venetian Republic.
In view of Galileo's rather implausible denial that he had ever held Copernican ideas after or ever intended to defend them in the Dialogue, his final interrogation, in Julyconcluded with his being threatened with torture if he did not tell the truth, but he maintained his denial despite the threat.
This set out the arguments for and against the Copernican theory in the form of a discussion between two men. It is written in the language of mathematics, and its characters are triangles, circles, and other geometric figures; His patrons, however, secured him the chair of mathematics at the University of Paduawhere he taught from until In the fall of Galileo began observing the heavens with instruments that magnified up to 20 times.
Galileo and his contemporaries were aware of this inadequacy because there are two daily high tides at Venice instead of one, about twelve hours apart. Through a student, he entered a controversy about the nature of comets occasioned by the appearance of three comets in The book was published in Holland after it was smuggled out of Italy.
In he wrote a letter to his student Benedetto Castelli — in Pisa about the problem of squaring the Copernican theory with certain biblical passages.
However, he was eventually persuaded to admit that, contrary to his true intention, a reader of his Dialogue could well have obtained the impression that it was intended to be a defence of Copernicanism. He also began his studies on motionwhich he pursued steadily for the next two decades.
These financial burdens may have contributed to Galileo's early desire to develop inventions that would bring him additional income. That deployment and, later, the unprecedented images that Hubble delivered represented the fulfillment of a year dream and more than two decades of dedicated collaboration between scientists, engineers, contractors, and institutions from all over the world.
On 26 February, Galileo was called to Bellarmine's residence and ordered: The musician in him recognized a principle similar to his lute. But his attacks on Aristotle made him unpopular with his colleagues, and in his contract was not renewed.
But the tide in Rome was turning against the Copernican theory, and inwhen the cleric Paolo Antonio Foscarini c. In January he discovered four moons revolving around Jupiter.
Publication of Il saggiatore came at an auspicious moment, for Maffeo Cardinal Barberini —a friend, admirer, and patron of Galileo for a decade, was named Pope Urban VIII as the book was going to press.
Galileo was then 70 years old. Having strayed from medicine, he decided he might as well study art and drawing in addition to science. Philosophy is written in this grand book, the universe, which stands continually open to our gaze. The pope convened a special commission to examine the book and make recommendations; the commission found that Galileo had not really treated the Copernican theory hypothetically and recommended that a case be brought against him by the Inquisition.
In the spring of he heard that in the Netherlands an instrument had been invented that showed distant things as though they were nearby.The great physicist and Italian astronomer had to face an inquisition for defending the new theories about the universe.
The scientific revolution of the Renaissance had their start in the Copernican heliocentrism and its culmination, a century later, in the mechanics of Newton.

His work on astronomy made him famous and he was appointed court mathematician in Florence. InGalileo was accused of heresy for his support of the Copernican theory that the sun was at the centre of the solar system.
Galileo's ink renderings of the moon: the first telescopic observations of a celestial object. In an Italian physicist and astronomer named Galileo became the first person to point a telescope skyward.
Galileo Galilei was born in the Italian city of Pisa on February 15, Physics and Art. Aged 18, Galileo stumbled into a mathematics lecture, changing his life and the course of scientific history. Galileo settled in Padua, where he taught mathematics, physics, and astronomy, making many momentous scientific discoveries.
