Outline for the course, class schedule, etc.

Tools and concepts that you will need to understand and use to pass this course.

Practice problems for the exam are now available as "Problem Set 99". They concentrate on material from early in the course -- you can use this week's (and last week's) problem set to study properties of the magnetic field.
