Galileo Galilee (1564-1642)

an Italian physician and astronomer, one of the founders of exact natural science. He lived at a time when the ideas of man’s liberation disrupted the middle-aged chains of the thought. He was extremely attracted by mathematics, physics and astronomy. He read the works of ancient scientists and philosophers. A professor of mathematics first in Pizza, then in Paddy, Galilee thought that observations and experience were the best way to get to know nature. He was the first scientist to study the celestial bodies with a binocular tube. The first tube that Galilee made magnified only 3 times. Galilee observed the Moon and discovered four satellites of Jupiter. By the movement of the sunspots he concluded that the Sun rotates around its axis. He was convinced that the stars on the sky are many more than the ones we see with the naked eye and that the Milky way consists of billions of stars. Galilee summarized his observations in the book “Dialogue about the two main systems in the world” (1632). Besides that, the scientist worked on many questions of the dynamics and with his research he became the precursor of Nuiton. The churchmen were strongly Galilee’s teaching. They took Galilee before the court of the inquisition and wanted to force him recant his doctrine that the Earth rotates. He was sentenced but to the end of his life he fighted against religious believes and achieved very much for the recognition of a new, scientific point of view. Despite of the prohibition of the pope, Galilee’s students had a monument built for him.
