Reviser of Astronomy Nicolas Copernicus gave a major effort in correcting astronomical ideas. He observed the heavenly bodies and came to the conclusion that contrary to current beliefs the planets could and probably did revolve around the sun. His ideas were ridiculed for a time. Years later Kepler and others, like Galileo, backed him up. Then he became praised by astronomers around the globe. Canon of Frauenburg 2 years ago if you went up into a certain tower at Frauenburg, Poland you would find Copernicus sitting by the window observing planets. It is curious that a clergy member started a revolution. It is even more curious that it was against the church's beliefs. As he grew older his responsibilities slackened and let him work on his astronomical charts. Remembering Copernicus Nicolas Copernicus was the founder of a theory aptly named the Copernican theory. He lived a full life from 1473 to 1543. During his life he defended a city, wrote books, observed planets, and served as a clergy member. In 1530 he finished writing his greatest work of literature, Concerning the Revolutions of the Celestial Spheres, but it was not published until 1543. He held the first copy of it on his deathbed. Nicolas Copernicus may have brought about major revolutions but all he really wanted to do was have accurate star and planetary star charts. He just happened to hit upon the right idea. He didn't really care how the planets moved just as long as he could say exactly when a planet would be where. He did this because Ptolemy's charts were slightly inaccurate. For five years Copernicus served his uncle officially as a physician. He studied medicine at Kacrow and other universities. Unofficially however he was almost like a son to bishop of Ermland, Luther Waczenrode.
