universe as this curious bishop's doctor and church official. In his quest to discover a beautiful and coherent system to describe the motions of the planets, Copernicus placed the sun in the center of the system and made the earth a planet traveling around the sun. Today it is hard to imagine our solar system any other way, but for his time Copernicus's idea was earthshaking. In 1616 the church banned his book Revolutions because it contradicted the accepted notion that God placed Earth in the center of the universe. Even though those who knew of his work considered his idea dangerous, Revolutions remained of interest only to other scientists for many years. It took almost two hundred years for his concept of a sun-centered system to reach the general public. None the less, what Copernicus set out in his remarkable text truly revolutionized science. For this, Copernicus, a quiet doctor who made a tremendous leap of imagination, is considered the father of the Scientific Revolution.Oxford Portraits in Science is an on-going series of scientific biographies for young adults.
