Question 1) Two of Keplers Laws destroyed perfection in the heavens. Give me each of the two aspects of perfect motion and for each, tell me which of Keplers Laws destroyed it. Question 2) Give me one of the arguments used against the sun-centered system of Copernicus, and then explain why we today dont accept that argument as valid. Question 3) The Greeks were being scientific when they thought about their idea of how the Universe must be put together because when their idea conflicted with reality, they modified their idea. The three Es of the Greeks were three of these modifications. List all three, and for each explain what problem each was trying to fix. [Hint: Ill normally not do this, but this is the first homework. In reading this question, please take note that I am NOT asking what each of the 3 Es were. Im asking what issue each addressed. A scientist doesnt make an idea more complicated unless there is a reason. Tell me about the reasons why the 3 Es were added to the Greek model.] Question 4) The motion of the sun is the foundation for our day and the (solar) calendar. But getting a solar calendar is far from easy. A) First tell me how you can use the sun to tell the time of day. B) Now, tell me who has/had the need for a solar calendar and why. C) Nomads historically have not used a solar calendar. Tell me why it would be hard for them to make a solar calendar, as well as why it wasnt as necessary compared to the people in part B). D) Tell me one way that you can use the sun to tell the time of year. E) Finally, what would happen if your culture made a mistake and had the wrong number of days a year?
