An Italian astronomer, physicist, engineer, philosopher, and mathematician who played a major role in the scientific revolution of the seventeenth century, Galileo Galilei was born on 15 February 1564 to Vincenzo Galilei and Giulia Ammannati. Galileo has been referred as not only the “father of observational astronomy”, but also the “father of modern physics”, the “father of scientific method”, and even the “father of science”. His impacts to observational astronomy consist of the telescopic confirmation of the phases of Venus, the finding of the four largest satellites of Jupiter which are named the Galilean moons in his honour), and the observation and analysis of sunspots. Galileo also worked in applied science and technology, formulating an improved military compass and other instruments. During his lifetime, most of the people supported to either geocentrism or the Tychonic system so Galileo’s advocating of heliocentrism and Copernicanism was debateable then.
Galileo Galilei Discoveries
At his father’s urging Gallileo enrolled at the University of Pisa for a medical degree although he seriously considered be a priesthood as a young man, Galileo had purposely been kept away from mathematics, since a physician made more money than a mathematician. However, he talked his hesitant father into letting him study mathematics as well as natural philosophy instead of medicine after accidentally attending a lecture on geometry. He invented a thermoscope, a forerunner of the thermometer, and published a small book in 1586 on the design of a hydrostatic balance he had invented this first brought him to the attention of the scholarly world.
In 1589 He was appointed as the chairperson of mathematics in Pisa. He was entrusted with the care of his younger brother Michelagnolo in 1591 after his father died. He moved to the University of Padua where he taught geometry, mechanics, and astronomy from 1592 until 1610. In the course of that period, Galileo made substantial discoveries in both pure fundamental science as well as practical applied science (kinematics of motion and astronomy for the former and strength of materials and pioneering the telescope for the latter). His other interest also involved the study of astrology, which at the time was a discipline attached to the studies of mathematics and astronomy.
Galileo Galilei Contributions
Through an innovative combination of experiment and mathematics Galileo made innovative contributions to the science of motion. He was one of the first modern thinkers to clearly assert that the laws of nature are mathematical. His work confirmed another step towards the subsequent separation of science from both philosophy and religion which was a major improvement in human thought. In accordance with observation he was often prepared to change his opinions. Galileo had to set up standards of length and time in order to perform his experiments, so that measurements made on different days and in different laboratories could be compared in a reproducible manner which provides a consistent groundwork to confirm mathematical laws using inducing thinking. Galileo showed a modern gratefulness for the proper relationship between mathematics, theoretical physics, and experimental physics.
Galileo died on 8 January 1642 at the age of 78 due to fever and heart problem.
