Class information

Your grade for the lecture portion of the course will consist of:

The lecture portion is 75% of your whole grade and the lab is 25%.

Office hours will be on Wednesdays from 2 to 5pm on the 9th floor of Stevenson. I can be found in either SC6906 (my office) or (usually) SC6924 (the Johns/Sheldon/Webster Lab area).

I am trying to reserve SC6105 on Tuesdays and Thursdays and will try to stay in the room after class to help with any questions on the course material. Right now the official class room is SC1117 in the math building. (SC1117 is undergoing renovation but they promised me it would be ready for classes...)

We will be using the Thornton Modern Physics book, and we will be reviewing thermodynamics etc. to start with. Page numbers refer to locations in Thornton. You can use either the 3rd edition or the 4th edition of Thornton.. The 3rd edition may be cheaper on-line for you! ("Modern Physics for Scientists and Engineers" Steven T. Thornton and Andrew Rex. 3rd or 4th editions)

WebAssign (Homework) Info

We'll be doing most homeworks on the computer this semester. The computer package we'll be using is called WebAssign. You can get to their info page by clicking on the link below.

Web Assign Info Page

Additionally I will hand out a problem or 2 each week for you to turn in. I expect to see all steps completely worked out in these problems and I will grade these myself to get an idea of how you are doing.
