"Mikołaj Kopernik (February 19, 1473–May 24, 1543), more commonly known by the Latin form Nicolaus Copernicus, was a Polish astronomer, mathematician and economist, mainly remembered for developing a scientifically useful heliocentric (Sun-centered) theory of the solar system. His main occupations and services rendered were in Royal Prussia, as church canon, governor and administrator, economist, jurist, physician, astrologer and military leader (conducting defense against the Teutonic Order). Amid all his responsibilities, he treated astronomy as a hobby. His theory about the Sun as the center of the Universe, opposed to the traditional geocentric theory that placed Earth at the center, is considered one of the most important discoveries ever, and is the fundamental starting point of modern astronomy and modern science itself (it inaugurated a scientific revolution). His theory affected many aspects of human life, opening the door for young astronomers, scientists and scholars to take a skeptical attitude toward established dogma."
