ASTRONOMY (ASTR)

IDEAs in Action General Education logoASTR 61.  First-Year Seminar: The Copernican Revolution.  3 Credits.  

This seminar explores the 2,000-year effort to understand the motion of the sun, moon, stars, and five visible planets. Earth-centered cosmos gives way to the conclusion that earth is just another body in space. Cultural changes accompany this revolution in thinking.
