There is an SA session tonight, 7:30 to 9:30 in SC 102.

I will have office hours on Monday from 4:00 to 5:30 pm. But also feel free to get in touch with me by email anytime, either to ask me questions about the material and exam or to schedule an appointment outside of my regular office hours.

The exam is on Tuesday morning (12/15) at 9AM in Kohlberg 115.

Study for the final exam! The exam will be open book. It will cover the material from the whole semester. You should be prepared to do problems like those from the homework as well as more interpretive problems (e.g. analyzing figures or images - as with some of the problems from the last exam). Bring your book, a calculator, and something to write with. You may put post-its in the book to mark pages and write short notes on them if you want. (You cannot bring in any other notes. No old homeworks or exams.)

You should use the class-by-class reading assignment documents as a guide to what the most important topics are. And you should be able to do all the problems on the homework assignments and (especially) on the two exams you've already taken. Note that I've given out my solutions to all the exams and homeworks (I will provide you with my solutions to the optional assignment that was due earlier today, by tomorrow).

Upcoming Events

Astro 16 students are members of the Department of Physics and Astronomy, and are encouraged to participate in department activities beyond the classroom. This includes attending regular talks – colloquia given by visiting scientists – and attending, and helping out with, the monthly telescope open houses at the Peter van de Kamp Observatory, on the roof of the Science Center.
