Undergraduate Program

Astronomy Courses

The department offers a variety of courses at all levels. Below is a list of all astronomy (AST) courses.

AST 102 RELATIVITY, BLACK HOLES AND THE BIG BANG

A physical and astronomical (but non-mathematical) picture of the workings of Einstein's theories of relativity, and their application to cosmology and to black holes and wormholes, the most exotic and energetic objects known to scientists. Our aims in this course are two: to demystify black holes, big-bang cosmology, and the nature of space and time for non-science majors, in order that they may evaluate critically the frequent references to these esoteric concepts in the press and in popular science and science-fiction literature; and to provide non-science majors with a glimpse of the processes by which scientific theories are conceived and advanced. Typical textbook: Kip Thorne, "Black Holes and Time Warps"

Prerequisites: None.
Last Offered: Spring 2019
