THE COURSE

What we experience in the everyday world of the macroscopic (scales much greater that atomic and molecular scales) is determined by the average microscopic behavior of a huge number of microscopic particles (molecules, atoms, free electrons, free photons, ....). The description of these phenomena is known as THERMAL PHYSICS. The discipline includes:


(1) How the distribution of energy among the particles in a physical system, and the transfer of energy between parts of the system, and interactions with the environment determines the microscopic properties of the system.

(2) How to determine the average values of these microscopic properties

(3) How to identify those average properties with the macroscopically observables
This is one of the deepest views we have of how nature operates and yields the observables, and it is expressed by some of the most elegant and encompassing theories in physics.

 

COURSE POLICY

As a student in this course, you are responsible for all material presented in the text and on the lectures, occasionally including supplemental material not part of the main textbook.
Careful attention should be paid to the homework assignments. These are most often much more than "plug-in" exercises, and are specifically designed to help you master the course material and to provide you with deeper intellectual understanding of the concepts covered in the lectures.

Do not fall into the trap of believing that you "know" and understand the course material -- even though you have great difficulties with the homework assignments. Learning physics is DOING PHYSICS. If you truly get stuck, do not spend more than one hour on any given assigned problem, but come and ask your professor for hints and help.

Mathematics is the language of physics. As supplemental material to go with this course, you should have a mathematical handbook which contains a fairly complete table of integrals, series expansions and other mathematical formulae. A good (and inexpensive) choice is the Schaum's Outline Series: "MATHEMATICAL HANDBOOK" by Murray R. Spiegel.

Using internet access from the Physics Majors' room, or the WSU Learning Center, from the WSU computer service building, or from a home computer, be sure to visit and extract information from the WSU/Physics WEB-page: "Computer Problems in An Introduction to Thermal Physics" at the WEB-site:
http://physics.Weber.edu/thermal/computer.html
The most pertinent of that material is reproduced here.

Two mid-term exams will be given on the days indicated in the lecture schedule. No make-up exam will be given without advance permission from your professor.

GRADING
Homework 12 homework sets 36% (i.e., 3% each)
Midterm Exam 1 exam 24%
Final Exam 1 exam 40%

FOR STUDENTS WITH DISABILITY: Any WSU student requiring accommodations or services due to disability must contact Services for Students with Disabilities (SSD) in room 181 of the Student Service Center. The SSD can also arrange to provide course materials (including this syllabus) in alternative formats, if necessary. Your professor will also be as helpful as possible in making reasonable accommodations as necessary and possible.
