ASTR 220   Deciphering the Sky: Practical and Historic Astronomy
DistributionNatural Sciences & Mathematics
Core AreaNone

An investigation of the observed motions of the stars, Sun, Moon and planets in the celestial sky. Study of the physical models that explain these motions. The historic and cultural development of our understanding of celestial motions will be considered. Using the planetarium capabilities of the Ho Tung Visualization Laboratory, observations will be made of the night sky from different locations on Earth over time intervals ranging from minutes to centuries. Basic algebra, trigonometry and graphs will be used to quantify and visualize these motions. Additional outdoor observing sessions will supplement the class instruction.
