Course Description: This course presents an introduction to mathematical tools used in theoretical physics, with emphasis on practical uses rather than formalism. Where possible, connections will be made with physical examples, particularly from electrodynamics, statistical physics, and thermodynamics. Approximate schedule of topics will be

Grading: Grading will be based 25% on periodic homework sets, and 25% each on three term exams. The term exams will tentatively be in class on September 22, [Exam 1 Solution] [Distribution] October 27, [Exam 2 Solution] [Distribution] and December 6 [Exam 3 Solution] [Distribution] Because the material is a sampler of many very different topics, there will be no cumulative final exam. Grading thresholds will be set as for an upper level course: an overall score of 40 will be worth a C, 50 will be worth a B, 60 a B+, 70 an A−, and 80 and up will be an A. I will retain the right to adjust the thresholds downwards (so 79 might become an A), but they will not go up. In addition, at each level there is a requirement on the number of homework sets turned in: 40% for a C, 50 for a B, etc. Students are expected to complete work at the time due, or as soon as possible in case of illness or other accepted, documented circumstance. There will be no last-minute makeups accepted.
The following paragraphs of advice on how to do well in Physics
are lifted from one of my colleagues.
(To put this into perspective, he also was once known to have his
posted office hours during class meeting time.)
This is your education, and you are free to make your own
choices, but you should listen to what they say:
I do not plan to take daily attendance, but it is to your advantage to attend class. You may spend most of your time sleeping, but in between you will have the opportunity to learn what subjects I think are important, and you can then concentrate on these subjects during your reading. If by some unfortunate set of circumstances you do miss class, do not ask me if I said anything important everything that I say is important. Instead, ask a classmate; she or he is likely to give an honest answer, and you won't offend me. There will be a substantial number of examples discussed in class that are not in the textbook, and examples in class often appear on tests. If you miss class you will not do well in this course.
Do the assigned homework. This is the drudge part of physics, but it is absolutely necessary. We will learn grand ideas and see their wondrous applications in class. But, your understanding is only superficial unless you can apply these same grand ideas to completely new circumstances. In course work, this is usually done with homework problems. Do not be surprised if the homework is frustrating at times; solving one challenging problem makes the next much easier. And homework problems often appear on tests. Doing all of the homework is the easiest way to improve your grade. Not doing homework is the easiest way to lower your grade.

Homework: Problem solving is a skill learned only through practice. Take advantage of the homework as an opportunity to learn how to recognize the right approach to a problem before it becomes exam time. While I encourage you to discuss the assignments with each other, what you turn in must represent your own work. As we also do when publishing research articles: if you obtain significant information from a published or human source, cite that source. This will often be as little as "Jackson, eq. (9.98)". If you work together, please identify other members of your working group. And, please, be sure that in the end your elegant solution in fact answers the question asked!
