An intermediate course in the application of basic principles of classical physics to a wide variety of subjects. Roughly half of the year will be devoted to mechanics, and half to electromagnetism. Topics include Lagrangian and Hamiltonian formulations of mechanics, small oscillations and normal modes, boundaryvalue problems, multipole expansions, and various applications of electromagnetic theory.Ph106bc covers electrodynamics at a level of sophistication beyond the introductory Ph1bc sequence. You will see much material that is familiar to you, but we will take a more rigorous approach, analyze more challenging physical situations, and also consider many topics not seen in Ph1bc. It is impossible to emphasize how important the core physics courses Ph106 and Ph125 are: these teach you the basic frameworks and techniques that you must know to do any physics.
Below you will find the outline of the E&M portion of Ph106bc. I will update the details of the topics covered in lectures, suggested reading, problem sets, and solutions as the term progresses. Assignments will be available on the website about a week before the due date. Note that they are listed in the week they are due, rather than the week they are assigned. The schedule for the lectures and assignments may change as the term progresses.
The problem sets and solutions are only accessible to computers with a Caltech IP address (either direct or by VPN). (Lecture notes are available to anyone.) Please let me know if you are enrolled in the class and this causes problems for you, and we can make other arrangements.
Targets for the links below will not be present until they are needed. If you find a broken link, try refreshing your browser first. If the target is still not present, email me.
In the suggested reading, G stands for Introduction to Electrodynamics by Griffiths, LN for Lecture Notes, HM stands for Classical Electromagnetism by Heald and Marion, and J for Classical Elecrodynamics by Jackson. Reading given in parentheses is optional (intended only to tell you where I am drawing material from).
