Galileo wrote a letter to the Grand Duchess Christina (who was she?) to answer a question she had raised about whether or not the Copernican theory that the earth moved was in conflict with religion, and especially the Bible.hy Galileo wrote it, and how he reconciles the apparent conflict between science and religion. What are his most convincing arguments, do you think, for saying that science and religion should not be regarded as antagonistic? What role does mathematics play in Galileo's argument? And how does he answer those who were concerned that a stationary sun and a moving earth were in conflict with the Bible, and with the story in Joshua (Book X: 12-14) where Joshua commands the sun to stop in the heavens over Gibeon in the battle with the Amorites in order to lengthen the day? What does Galileo say is wrong with this argument? And why is this important to the point Galileo wishes to make about the Scriptures? In a final paragraph, summarize your evaluation of the "Letter" and whether you think it was an effective defense of Galileo's ideas or not.
