Labs

The labs are bound into a coursepak which you can buy at the University Bookstore NEXT MONDAY! They should be turned in to Oliver in Section!

If you prefer, click here to download a PDF copy of the coursepak (Warning: it's big!). You may not want to print out the images for the Galaxy Classification Lab, since you will be given copies to use in Section.

Exams

Midterm: Wednesday, November 7 (in class; Sig 227)
Final Exam: Monday, December 10 (8:30-10:20; Sig 227)

All exams are no notes, closed books.

Grading

Section: 50% (Problem Sets, Quizzes, etc)
Midterm: 20%
Final: 30%

Note the high weight given to your work in section! If you don't turn in your labs and problem sets, you will not pass!

I do not grade on a curve, meaning that if everyone in the class does extraordinarily well, everyone can earn a 4.0. However, if a particular exam turns out to be exceptionally hard, I will ease up a bit on the conversion from percentages to grades.

If you get this many points... I guarantee you will get at least this grade.

Exceptions?

If you want special permission to turn in work late, or to take an exam at a different time, you must make arrangements with me in advance!

As a rule, I only grant exceptions in truly exceptional cases, and do not grant them when it would not be fair to offer them to only one person in the class. For example, if you need to turn in a problem set late because you're having chemotherapy, I will gladly help accomodate you. However, if you would like to do extra credit work because you're disappointed in your grade, then I will probably not grant you an exception, unless I decide to offer it to the class as a whole.

In general, keep me informed.

Textbooks

The official textbook is "Stars, Galaxies, & Cosmology: The Cosmic Perspective" by Bennett, Donahue, Schneider, & Voit. It covers astronomy at a basic, non-mathematical level, and gives the reader a good physical understanding. There is also a more comprehensive version of the book, called "The Cosmic Perspective" that contains the same material, but also some additional chapters on planets. If you find the longer version more cheaply, go for it and just ignore the other chapters. We will be using the fourth edition, but it's not drastically different from the third edition. If you can find the latter used, and don't mind giving up the on-line material (which can be helpful), feel free to use the older edition if it saves you money. I will put copies of the book on reserve in the Physics-Astronomy library (6th floor of PAB).

The Cosmic Perspective, Bennett, Donahue, Schneider, and Voit.

Prerequisites

None, officially, but we will be using algebra and logarithms from time to time. I will also assume that you can handle the Web.
