How Did Galilei Contribute To Science

Decent Essays
Galileo Galilei made contributions to the fields of physics, astronomy, cosmology, mathematics, and philosophy. He was an extraordinarily intelligent man and had a big part during the Enlightenment. He made his first discovery in 1581 while he was a student at the University of Pisa, where he originally went into medicine but switched his focus to mathematics. He described the rules that governed the motion of a pendulum. He was then the chair of mathematics at the Universities of Pisa and Padua from 1589 to 1610.

In 1604 Galileo published The Operations of the Geometrical and Military Compass, revealing his skill with experiments and practical technological applications. He invented a hydrostatic balance for measuring small objects, that

He discovered four new “stars” orbiting Jupiter, the planet’s four moons to be exact, he called the “stars” the Medician stars. With these new discoveries he had gained even more evidence to support the Copernican theory. He published a treatise on his discovery which soon made him a very well-known man in Italy. Many people including scientists and theologians said his theory differed from the Aristotelian view of the Universe, and his depiction of the rugged surface of our own moon greatly disagreed with the idea of heavenly perfection.

In 1632 Galileo published his “Dialogue Concerning the Two Chief World Systems,” he presented arguments for both sides of the heliocentrism debate. He had no luck fooling anyone with his attempt at balance, he was called before the Roman Inquisition in 1633, he tried to deny advocating heliocentrism, and later said he did it unintentionally. He was convicted of “vehement suspicion of heresy,” and was threatened with torture to express sorrow and curse his error. He was nearly 70 years old at the time of his trial, and he spent the last years of his life under house arrest. He died in 1642, on the 8th of January, after suffering a fever and heart
