PHYS 23 final is scheduled in Harold Frank Hall 1104 on Friday, December 11, 2015 from 7:30-10:30 pm

 

Homework assigned every Wed and is due the following Wed.

Course grade = Homework 40% +Midterm 20% + Final 40%.

 

Required:

  1. Purcell, Electricity and Magnetism. Third edition.
  2. Calculations must be done, so a scientific calculator (must have trig, exponential, etc) is essential.

Recommended:

Purcell is a challenging textbook, and assumes that you have or are rapidly developing good ability in vector calculus. For those who want to brush up on their vector calculus, Schey, Div, Grad, Curl and All That is a good resource.
