Born in Torunń， he began his university studies in Krakw in 1491, where he studied canon law and Latin and Greek classics. However, he also had an interest in mathematics and astronomy. After obtaining his degree of Doctor of Canon Law (教會法規(guī)博士學位)in Italy in 1503, Copernicus returned home to Warmia in Poland to serve as Canon (＝priest)．,,In 1530, Copernicus completed his great work De revolutionibus orbium coelestium (《天體運論》)．Copernicus knew that these findings would lead him into trouble with the Roman Catholic Church (羅馬天主教), so he was in no hurry to publish his theory. He only published it as he lay dying in 1543.
