There is an SA session this Sunday night at 7:30 pm in SC 102. There is currently no active homework assignment. The SA session is a great opportunity to review for the second midterm, on Wednesday night (7:30 to 9:30 pm in SC 102). Information about the exam will be posted by Saturday night, but it will cover the material from the week of the first midterm through stellar end states (Ch. 18).

We have a colloquium this Wednesday afternoon at 4:30. The topic is gravity waves.

Take a look at the reading assignment for Tuesday's class [pdf]. The topic is the Milky Way and my reading instructions for Ch. 19 are quite specific.
