What are the major differences and similarities between Aristotle’s view of the cosmos and Copernicus’s view of the cosmos? Why was Tycho Brahe’s observations and data so important. To what end did they lead? Explain each of Kepler’s three laws as if you were explaining them to elementary aged children. In other words, do not use any mathematical symbols and try to avoid mathematical wording in your explanations of each law. Describe what an observer sees in the sky when a planet undergoes retrograde motion (in terms of direction of motion, time frame, etc.). Then explain the underlying reason is for retrograde motion (in terms of relative planetary orbits). This module largely presented a typical Western European view of the development and history of astronomy. Give at least two examples of non-Western Europeans who contributed to the development of astronomy throughout history. Cite your sources.
