Introduction to Methods of Theoretical Physics

Fall 1998 Schedule of Classes

This page may be updated and changed after the course has begun. I will try to inform everyone when changes are made, but be sure to check the current version of this page before doing your homework or preparing for class.

Most classes will be two consecutive 50-minute periods with a ten minute break inbetween. The material that will be covered is indicated for each period, as well as the relevant reading in the textbooks. Textbook material is referenced by the chapter and section. A few of the classes will be carried out in one two-hour block in one of the studio classrooms on campus. The location for each class will be announced when known, and indicated on the date.

The homework assignment indicated on a date is due on that date at the start of class. Homework is due on most days.Follow the link to get a pdf file describing the assignment. For postscript files and other information on homework, see the homework page.

Class dates are listed here. Click on the date to get jump to that day.
