Italian scientist, one of the founders of modern physics and telescopic astronomy.

He was born in Pisa, Italy, in 1564. Galileo Galilei is an Italian scientist who is considered the father of modern physics. Galileo, whose name is mentioned with the scientific revolution, besides doing many studies in the fields of physics, astronomy and astrology, he also had philosophical views on these issues. Focusing his attention more on motion, Galileo developed the physics of the heliocentric system of astronomy.

Born on February 15, 1564, in the city of Pisa in the Tuscany region of Italy, as one of the six children of Vincenzo Galilei, one of the well-known musicians of his time, Galileo started his medical education at the University of Pisa in 1581 after completing his primary education in Florence. Galileo, who had to drop out of school due to his financial situation, turned to mathematics from 1583 and became a professor in Pisa in 1589 with his studies on this subject.

Believing that pendulums, floating bodies and their kinetics should be handled mathematically with a different thought than Aristotelian physics, Galileo threw weights from the Leaning Tower of Pisa and showed that all falling bodies had the same acceleration and proved Aristotelian logic wrong. Determining that free fall is a motion with constant acceleration, Galileo showed that the distance traveled during free fall is proportional to the square of time. As a result of this experiment, Galileo, who came face to face with old professors, left Pisa in 1592 and came to the chair of mathematics at the University of Padova.

In 1597, Gelileo, who commercially introduced the compass that can also be used for military purposes, invented a primitive thermometer and a pendulum for the measurement of human heartbeat, just after 1600.

After learning that the telescope had been invented in the Netherlands in 1609, Galileo produced a more advanced telescope himself, and used it for astronomical observations. Galilei Galileo, the first scientist to use the telescope for astronomical purposes, made important observations with the telescope he produced and wrote these observations in his book, Siderius Nuntius, in 1610.

His book, in which he published his first observations on the lunar surface, star clusters, and the Milky Way, and in which he mentioned the existence of Jupiter’s four moons, aroused much interest and made him a court mathematician in Florence. While giving information about the phases of the planet Venus and the shape of Saturn, he discussed the Ptolemaic system in astronomy. Galileo, who also observed the Sun and proved that the shadows on the Sun were spots, revealed that they were neither the shadow of Mercury as it passed in front of the Sun nor the small celestial bodies between the Sun and the Earth.

Galileo, who went to Rome in 1611 and became a member of the Academy of Sciences there, published his book on hydrostatics, which caused the objections of many professors, on his return to Florence, and his work on sunspots in 1613. Galileo, who was subjected to heavy pressure from the priests because of this work, in which he openly defended the Copernican system, went to Rome in 1615 to defend his claim. The commission, which was established by Pope Paul V in 1616 to examine his books, did not ban Galileo’s books, but asked him to abandon the claim that the world rotates.

Returning for a time to the practical side of science and developing the microscope, Galileo was confronted by the church in 1618 with the discovery of three comets. VIII of a friend. After being elected Pope as Urban, Galileo was summoned to Rome and brought to the Inquisition court, whose work “Conversations on the System of Two Universes” was published in 1632. After this, Galileo, whose book was banned in 1633, was sentenced to life imprisonment.

Imprisoned at the age of seventy and blinded in 1636, Galilei Galileo died in Arcetri on January 8, 1642.
