Weekly Homework is homework in addition to the Class-to-Class Homework. It is due every week at the beginning of the Friday class (except for the first week, Fall Break and Thanksgiving Break). **You must turn in two or more "exercises" from each textbook chapter**. You can choose which exercises to turn in from the collection in the textbook, with two restrictions: (a) they must not have been assigned in the Class-to-Class Homework or Exams, and (b) their level of difficulty must be two or three stars (for optics, you can choose from the list of acceptable problems in Fowles at the bottom of this page). A list of recommended exercises is provided below.
