Welcome to Physics 513, the first of a three-quarter sequence of graduate classical electrodynamics. I hope you find this course challenging and stimulating. The topic of electrodynamics is crucial for understanding the underpinnings of the physical and biological sciences. It's also crucial for modern technology. You will need a working knowledge of Jackson chapters 1-16 in order to converse sensibly with your colleagues. Regarding the course: We will use Jackson's text "Classical Electrodynamics". You might want more details than found in Jackson, or perhaps you'd like an alternative approach. In which case you might want to look at Panofsky and Phillips "Classical Electricity and Magnetism". A very good, very readable, book for some slightly more formal aspects of the classical field theory is Landau and Lifshitz "The Classical Theory of Fields". Another nice thing about Landau and Lifshitz is halfway through the book you're on to General Relativity rather seamlessly. A slightly more elementary alternate text is Slater and Frank "Electromagnetism". Most homework problems are adapted from Smythe "Static and Dynamic Electricity." There's no perfect text, and every text has gems scattered throughout. Mathematical methods are interspersed throughout the course as needed. For a math refresher, you could refer to Dennery and Krzywicki "Mathematics for Physicists". That said, this quarter we will follow Jackson's text somewhat closely.

SyllabusThe syllabus for 513 starts with chapter 1 in Jackson. We'll then follow the text in more or less the text ordering. We will supplement Jackson's presentation with added material. You should read the relevant text and added material before class; this will take time but there's a big payoff in your understanding.

Grading40% of your grade is assigned to the midterm exam, 40% to the comprehensive final exam, 20% to the homework.

Midterm and final exams: There will be one closed-book midterm exam and a closed-book final exam. An equation sheet containing selected numerical values and major equations will be provided for each exam, so memorizing equations and numerical values should not be necessary. Calculators are permitted, but text storage and graphics functionality must not be used. Cell phones, radios, etc. are not permitted. Laptop computers are not permitted. Exams are to be your own work; you are not permitted to collaborate with any other person. The Physics Department reserves the right to ask for valid identification from any student during examinations. If you start working on the homework the day before it's due, you will not finish on time. The graders will look for neatness and logic of presentation, points will be deducted for lack of either.Note that there are no make-up exams or make-up homeworks. Students with outside professional, service, or career commitments (i.e. military service, professional conference presentation, etc.) conflicting exactly with the exam dates must contact the instructorearly in the quarterto establish alternate procedures. Students who miss an exam or homework due to illness should contact the instructor as soon as you are able to discuss alternate procedures. Except for debilitating illness, students who miss an exam or homework without making prior arrangements with the lecture instructor will get a zero for that score. Except for illness and circumstances noted above, a final grade of 0.0 may be assigned to any student who misses a midterm exam and a final grade of 0.0 will be assigned to any student who misses the final exam.Re-grades: If you believe that points on an exam or homework were incorrectly totaled or if there's a gross error in the grading, you may submit an exam or homework for regrading. To do so, you must resubmit the exam or homework to the instructor no later than at the beginning of the lecture following the one in which it was returned. You must write a brief note on a separate piece of paper explaining the possible error in the grading, and staple this note to the front of the exam or homework pages when you submit them for re-grading. Do not make *any* changes or marks on any pages of the exam or homework. A request for a regrade may result in re-grading of the entire exam or homework. Therefore your total score may increase or decrease.Lecture homework will be assigned and collected weekly. You'll usually turn in homework on the due-day at the beginning of class. You may also leave the homework in the instructor's mailbox in the Physics Department Main office by 10:45am on the due-day. Late homework receives zero points. Note that not all the homework problems will be graded. If you start working on the homework the day before it's due, you will not finish on time. The graders will look for neatness and logic of presentation, points will be deducted for lack of either. I strongly encourage you to work collaboratively, but your submitted work must be your own. Homework:

The lecture instructor and graders will ignore re-grading requests that are not reported promptly. For administrative issues, it's best to contact me via email. But, for physics questions, please don't use email (unless they are of the "yes/no" variety). Physics is best discussed at my office hours. You are welcome to come by outside my office hours, but please don't be offended if I'm too busy to talk. Communication:
