Astronomy 101:

Principles of Astronomy

San Diego State University

Fall 2009

The Crab Nebula

Finding our place in the universe has been a perennial human pastime. Here we present the results of this ongoing endeavor, covering such topics as the solar system, stars, galaxies, black holes, and cosmology. Particular emphasis will be placed on the historical development of ideas, as well as their philosophical implications. The class assumes no prior background in astronomy, although a general knowledge of science at the high-school level will be helpful. Mathematics will be limited to algebra and geometry.

Prerequisite: Interest.

BallThanks for a great semester!

...and should questions about the Universe linger, feel free to drop by my office hours next semester; just because the course is over, it doesn't mean the door is closed. -Doug
