Compare and contrast the Ptolemaic System with the Copernican System. Are there any similarities? What are the key differences? How did the prevailing ideas or perspectives of society affect each of these explanations?
What will be an ideal response?
The Ptolemaic model represents a geocentric system, with planets moving in perfect circles around a motionless Earth. Given that Ptolemy used an incorrect model to formulate his theories, it is a miracle that he was able to account for the planets' motions. His findings went unchallenged until the 17th century. On the other hand, the Copernican System is a heliocentric model, with the Sun in the center of the solar system and the planets orbiting it. Also, the Copernican system included the idea that the planets' orbits were elliptical in shape rather than perfect circles. Nicolaus Copernicus never had to deal with the criticism of his ideas because he died as they were being published. However, one of his followers was killed during the Inquisition.
