Grading: About 50% of the semester grade will be based on assigned homeworks. In addition, each student will be required to prepare a term paper, which will count for most of the remainder of the grade. These may be in the nature of a review of a topic not fully covered in class. They may be more concentrated efforts dealing with a specific problem, and, if so, students are allowed (indeed, encouraged) to treat a problem within the scope of their thesis research. The efforts may be theoretical, numerical or, in the event that tank setups permit, experimental. People may work alone, or, if the scope of a project warrants it, in groups of two.
