Astrophysical Sciences 203

The Universe

Spring 2008


The following course outline is approximate, and may change depending on how the course progresses. In particular, the dates for the observing and review sessions are likely to change around; watch your e-mail for updates. Numbers in parentheses are chapter numbers in our textbooks (CP for Cosmic Perspective, TTEU for Time Travel in Einstein's Universe) which (approximately) cover the material of these lectures. However, you are responsible only for the material in the lectures and in the problem sets, not for all the material in the CP text (you will be responsible, however, for all the material on TTEU). There will be many occasions when the lectures cover material not discussed in the text, especially in the second half of the course, where the coverage of the text is spotty. Some supplementary reading material will be supplied.

Detailed outlines of each lecture will be made available on this page (simply click on the lecture as listed below), usually within 24 hours of the lecture itself. Click here for a guide to what you should read in the textbooks.

The exact schedule of the observing sessions may be changed, due to the vagaries of weather. Review sessions for the midterm and final will be scheduled.
