Nicolaus Copernicus, a Polish mathematician and astronomer, is best known for his revolutionary ideas regarding the structure of the solar system. Born on February 19, 1473, in Toruń, Poland, he lived during a time when the prevailing belief was that the Earth was the centre of the universe—a view known as the geocentric model. Copernicus's work laid the groundwork for modern astronomy, fundamentally changing the way humanity perceives the universe.
