Physics 704 Electricity and Magnetism. Spring 1998

Text: Jackson, J.D. Classical Electrodynamics.

Physics 704 is to cover the material in the first 8 chapters of Jackson's book; 705 covers the rest! This is a tall order, for you and for me. The objective in studying this material is not just to learn the physics of electromagnetic phenomena, but also to learn a set of mathematical techniques which are useful in many other branches of physics. In order to present the material in a way which emphasizes how a given technique can be applied in differing physical situations, and thus to avoid a good deal of duplication of material, I have attempted to construct a class schedule which does not follow the order of Jackson exactly. It is given below. We may not adhere to this schedule exactly, but it should be a guide for your reading and we can discuss how to proceed as things deviate from the plan.

Please try to read the appropriate section of the text before class. The material will undoubtedly be mysterious the first time you see it, and you will get more from each class if you have looked at the material in advance.

Assigned problems are listed on the schedule. Doing problems is the essence of a class based on Jackson. I shall collect and grade these every week. Do not get behind! The farther behind you get, the harder it is to catch up. Your grade for the class will be heavily based on these problem grades, although a good deal of credit will be given for a good attempt. There will be a take-home midterm, and a take-home final. Problems and the midterm are due at the beginning of the class period on the day indicated. Assignments turned in late will be accepted only under exceptional circumstances.

Grades will be assigned on the following basis:

Homework problems: 30%    Midterm: 35%    Final: 35%

Please feel free to discuss all aspects of the class with me at any time. Discuss the homework problems among yourselves as well as with me (exams should not be discussed, however). Try to attend published office hours, but also feel free to knock on my door whenever I am there (I'll tell you if I am busy!) My official office hours are (tentatively) M 2-3pm, W 3-4pm, F 11-12am. It's usually a good idea to make an appointment.

As graduate students, more is expected of you. You may find it helpful, indeed necessary, to use reference materials other than Jackson. You should have access to a mathematical reference work listing integrals as well as properties of mathematical functions such as Legendre polynomials and Bessel functions. The book store has a few copies of Gradshteyn and Ryzhik if you want your own: otherwise using the library should suffice. Other books dealing with the material include: Landau and Lifshitz, Classical Theory of Fields; Morse and Feshbach, Methods of Theoretical Physics; Jeffreys and Jeffreys, Mathematical Physics, especially Chapters 6,18,21,22 and 24.

This class will be a challenge for all of us, and I hope that we can meet it together.
