Readings

Readings from the textbooks should be done BEFORE the lecture. That way the lecture can be used to clarify, and not just introduce, concepts.

The numbers refer to chapters in Carroll and Ostlie.
S refers to pages in Shu's text.
(Readings in Shu are not required, but are recommended.)

All students should read, or at least be well-acquainted with, the basic astronomical concepts covered in AST 203.
