Line 140:
Line 140: + + − Copernicus worked for years on his book describing his theory, and did not publish it until near the very end of his life. He entitled it, “De revolutionibus orbium coelestium” (“On the Revolutions of the Heavenly Spheres”), and published it in 1543. The work was far from perfect: Copernicus assumed that the planets moved in circular revolutions (they actually revolve in ellipses, though the orbit of the earth is nearly circular), and Copernicus also thought that the sun stood motionless as some kind of stationery temple in the universe. He also thought the sun was at the center of the universe. − [[Image:Copernican model from book.jpg|right]]

A remarkable Polish scientist named [[Nicolaus Copernicus]] (1473-1543) made a stunning claim that rocked the religious and scientific world: he asserted that the earth revolved around the sun, not the sun around the earth. “Finally we shall place the Sun himself at the center of the Universe. All this is suggested by the systematic procession of events and the harmony of the whole Universe, if only we face the facts, as they say, ‘with both eyes open.’” With this bold declaration, Copernicus began the “Scientific Revolution,” which rejected geocentric (earth-centered) theory of the universe dating back over a thousand years to Ptolemy.

Copernicus worked for years on his book describing his theory, and did not publish it until near the very end of his life. He entitled it, “De revolutionibus orbium coelestium” (“On the Revolutions of the Heavenly Spheres”), and published it in 1543. The work was far from perfect: Copernicus assumed that the planets moved in circular revolutions (they actually revolve in ellipses, though the orbit of the earth is nearly circular), and Copernicus also thought that the sun stood motionless as some kind of stationery temple in the universe. He also thought the sun was at the center of the universe. A diagram from his book displaying circular planetary orbits around the sun is to the right.
The reception to his work was initially positive within the Catholic Church, which Copernicus served, but Protestants whose faith it conflicted with cited some literal interpretations of the Bible, such as the account of how Joshua benefited from the sun standing still as it passed over the earth. “And the sun stood still, and the moon stayed, until the people had avenged themselves upon their enemies. Is not this written in the book of Jasher? So the sun stood still in the midst of heaven, and hasted not to go down about a whole day.” Joshua 10:13. There were few Protestants in Poland then (or now), and thus Copernicus died without much controversy.
