Textbook: Thermal Physics, 2^nd Edition, by Charles Kittel and Herbert Kroemer

Chapters to be covered: Ch 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

Method of Evaluation: Grades will be determined by the use of weekly homework assignments and in-class exams.

Grading breakdown

3 - 1 hour exams	60 %
Homework (see below)	30 %
Attendance	10 %

Approximately every week, I will assign homework problems. Homework is due one week after it is assigned. It is to your advantage to stay current on the homework as it provides you with additional practice necessary for the exams.

All 1 hour exams will be closed book, closed notes.

Course Objectives: The objective of this course is to gain a detailed understanding of the techniques and descriptions used in modern thermal physics.

General Notes: All of the lecture notes, as well as this syllabus, are posted under Dr. Suson's home page. Those documents are available in three different formats: Word for Windows, HTML, and Postscript. Follow the links on his home page to reach the version that you are interested in. These documents can be downloaded and printed out, although Dr. Suson would prefer that they not be widely distributed at this point in time.

Homework assignments and solutions will be posted under his home page as well. The fax number is connected to the fax/modem in his office, so as long as he is in the office, I will see the fax fairly quickly. You can also reach me via e-mail.

Other communications are provided through the use of a chat room and a web-based news server. Use these to post questions, discuss opinions, and share thoughts with your classmates on every campus.
