Copernicus The Founder

Copernicus was graduated in the University of Bologna, situated in Italy. He got the uppermost room in a cathedral tower so that he could continue astronomy measurements which he did. Copernicus was ordained as a Priest in a Catholic Church, and then returned to Poland to work for his uncle, who is a Bishop at the Frauenburg cathedral called Waczenrode. At that time people throughout the world believed a model of the universe created by the Greek scientist called Ptolemy which is more than 1,500 years old. According to Ptolemy, the earth was the centre of the universe and never moved and the sun and planets revolved around the earth in great circles, while the distant stars were perched the way out on the great spherical shell of space. But careful measurement of the movement of planets didn’t fit with Ptolemy’s model.
