In general, homework sets will be first posted here on Fridays, and due the following Friday at the beginning of class. Solutions will be posted in the afternoon or evening of the day the homework is due. No late homework will be accepted, short of a Dean's excuse. One homework grade will be dropped-- as for the quizzes, this covers all possible reasons for a late or missing homework. Homework is worth 20% of your grade. Expect to spend 1-3 hours on each homework assignment. Please do not email homeworks! Please print them out and bring them to class. There are just too many of you for us to be able to print them out.
Your computer should have the free Adobe Acrobat Reader software installed so that you can view and print out the homework assignments, which are in PDF format. Duke's Office of Information Technology can help you to install this software if it is not already available.
Guidelines for homework (from Henry Greenside's course, valid also for this one!)
For problem 17-50, some printings of the textbook say that the distance to Sirius is 26 light-years. The distance is in fact 8.6 light-years.
In problem 22-42, they mean Fig 22.17, not Fig. 22.16
