1. (The big one): How do Galileo's observations through the telescope provide evidence for the Copernican view of the cosmos over the Ptolemaic-Aristotelian one?
2. What is the aim of Galileo's dedicating The Starry Messenger to Cosimo II de Medici?
3. What astrological claims appear in the dedication to Cosimo II?
4. List of the three main discoveries Galileo makes with the telescope (that he reports in The Starry Messenger).
5. What does Galileo learn about the moon that was previously unknown?
6. Why would it be provocative for Galileo to claim that "the moon is like another Earth" (p.34)?
7. What is the relevance of Jupiter's 4 moons (which Galileo calls the "Medicean stars") to the debate between the Copernican and Ptolomaic-Aristotelian theories of the cosmos?
8. How, exactly, did Galileo's exposure to (and probable study of) perspectival drawing (or 'disegno') enable him to discover what the surface of the moon is like? (And why didn't Thomas Harriot, who looked at the moon through a telescope 6 months before Galileo, figure it out?)
9. How does Fig.7.1 relate to Fig.7.16?
10. Did the Roman Catholic Church reject Galileo's claims about the surface of the moon?
