This page is intended to provide a backup copy of the materials displayed in lecture, announcements relevant to the class, and access to the wealth of astronomical information on the World Wide Web.

Latest update (most recent items are in red): Tue, Dec 17, 2002 20:32
Displays from lecture ... About Ritter Planetarium ... Links to astronomy resources

Office hours for exam week: M & W 2 - 6 PM, RO 205. Quiz 6 and 7 makeups and Homework 13 have been graded and will be available for pickup during office hours Wednesday and at the final.

The final exam will be comprehensive, covering chapters 1 through 11 to the extent that they were covered in class. Study guide for final exam here (PDF)

Help with math and physics (not necessarily astronomy) is available at the Help Center of the Department of Physics and Astronomy. More information here.

Information on Web project, due Thursday, December 12, here.

Homework policies announced in class Tuesday, September 10, 2002 here.
