Unit 1 Great Scientists英文教案
nicolaus copernicus was a polish astronomer (1473-1543). born in torun, he began his university studies in krakow 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 (《天體運行論》).copernicus knew that these findings would lead him into trouble with the roman catholic church (羅馬天主教教徒), so he was in no hurry to publish his theory. he only published it as he lay dying in 1543.
though copernicus did not live to hear of its extraordinary impact, the book which first suggested that the sun, not the earth, is the centre of the universe is now recognized as one of the most influential scientific works of all time.
