**23-Jan-2004:** The exams have been graded and
the course grades computed. You may send me an email to find out
your course grade and/or see me at my office to pick up your
exam. On the whole, you did well! Here are the
final,
solutions, and
point distribution on the
final. Maximum: 60 points, average: 49.6, standard deviation:
8.9, number of students: 22.

**20-Jan-2004:** Solutions to last year's final.
Also, solutions to Homework 11 have been posted and the graded
homeworks may be picked up in the department office.

**18-Jan-2004:** A "reTeXed" version of last
year's final has replaced the original version. This corrects
some problems with missing fonts (I hope).

**30-Dec-2003:** Schedule for the reading and
exam period:

Thursday, January 8, 7pm. Problem Session (Homework
11), Fourth Floor Lounge.

Monday, January 12, Homework 11 due in
Department office by 5pm.

Monday, January 19, 1:30 pm, Room A06, Review. (Will work last
year's final and answer questions.)

Wednesday, January 21, 1:30-4:30 pm, Room A07. Final Exam.
(Calculators allowed, but only for calculations, not for storing
things! Books, notes, cell phones not allowed.)

**7-Dec-2003:** Here is last year's final. Note that there is a problem on
mixtures. We skipped the mixtures chapter this semester. However,
you should still be able to do the problem just by applying what
you know about free energy, entropy, etc.

**26-Nov-2003:** This week's problem session is
moved from Sunday, November 30, to Monday, December 1, at 7pm in
the 4th floor lounge. Also, the due date for this week's homework
assignement is moved from Tuesday, December 2, to Wedensday,
December 3, at 5pm in the department office. Both in honor of
junior paper drafts being due! Have a happy Thanksgiving!

**21-Nov-2003:** You'll notice there are two
lectures (numbers 25 and 26) for Monday, November 24. Lecture 25
covers cryogenics, K&K chapter 12. Judy Lau already gave a
talk on practical cryogenics, so lecture 25 will not actually be
covered in class. Nevertheless, you should read it and chapter
12. There are a couple of homework problems from chapter 12.

**14-Nov-2003:** On Monday, November 17, 2003,
Judy Lau will talk in place of the regular lecture. She's a
second year student and will describe her "Generals Advanced
Project" to build a refrigerator to operate unattended on the top
of a mountain in Chile.

**6-Nov-2003:** Lecture 19 has been replaced to
correct an error in the discussion showing that all reversible
engines have the same efficiency.

**27-Oct-2003:** The midterm and homework
distributions.

**24-Oct-2003:** The midterm and solutions.

**16-Oct-2003:**
Schedule for midterms week:

Sunday: regular evening problem session for homework 5

Monday: HW 5 due at 5pm **a day earlier than
usual**

Monday class: Review

Tuesday: Kumar will lead a review, 7:30pm, 4th floor lounge

Wednesday class: In class midterm

Friday class: Will anyone be around for class?

**12-Sep-2003**:
Reminder, we will meet in room A06 starting Monday, 15-Sep-2003,
and for all lectures after that.

**12-Sep-2003**:
Problem sessions are on Sunday evenings, 7pm, in the Fourth
Floor Lounge, Jadwin 403, starting 21-Sep-2003.

**Course Instructor:**
Ed Groth, Jadwin 264, x8-4361,
*groth@physics.princeton.edu*.

**Office Hours:** Most afternoons - give a call before walking
across campus! Almost surely Wednesday afternoons, 2:00-4:00 pm.

**Teaching Assistant:** Kumar Raman,
Jadwin 423,
x8-5983,
*ramank@princeton.edu*.

**Office Hours:** TBD

**Course Manager:** Martin Kicinski, 208,
x8-4408,
*kicinski@princeton.edu*.

**Lectures:** Monday, Wednesday, & Friday,
10:00-10:50 am,
Jadwin A08.

**Problem Session:**
Sunday evenings, 7pm, Fourth
Floor Lounge, Jadwin 403.
Starting 21-Sep-2003.

** Text:** Kittel & Kroemer, *Thermal Physics*
2^{nd} ed., Freeman.
(to be followed
closely or loosely depending on the topic)

** Others:** Mandl, *Statistical Physics*, Wiley. Similar to K&K.

Reif, *Fundamentals of Statistical and Thermal Physics*,
McGraw Hill. Also similar to K&K.

Feynman, *Statistical Mechanics, a Set of
Lectures*, Addison Wesley. This is fairly advanced, but it's
always worthwhile to see what Feynman has to say.

Callen, *Thermodynamics*, Wiley. A classic treatment of
thermodynamics.

I've asked that all the above be placed on reserve at Fine Library.

**Homework:** Assigned Monday (I will try, but sometimes the
assignment may not be ready until Wednesday!), due the next
Tuesday in the department office (208) by 5pm,
returned the next Monday. 40% of grade. Collaboration
encouraged (but not copying!). Late homework may receive only
half or none of the grade depending on how late it is and how it
fits into the grading schedule!

**Midterm:** In class, Wednesday, October 22, 15% of
grade. (Note: this is a departure from previous times I've taught
this course when there was no midterm exam.)

**Final:** 45% of grade.

We will start by following K&K and cover fundamentals of statistical mechanics and thermodynamics, including temperature and entropy. We will cover the Boltzmann, Bose, and Fermi distributions; black body radiation; chemical potential; Gibbs free energy; and phase transitions. Then we'll consider some of the more advanced topics in K&K. A more detailed syllabus is in the table below.

The lecture notes and the homework assignments will be available for downloading. Note that I write the lecture notes mainly so I know what I'm going to say. I like to distribute them so you can follow along in lecture rather than having to worry about taking notes.

The notes and assignments are written in TeX and converted to postscript which is converted to PDF. You will need a to be able to view and print PDF for downloading to be useful! Acrobat Reader from Adobe is a free viewer for PDF format. The files are large because the fonts used by TeX are embedded in the files.

If you discover errors or typos, or just plain unclear passages, let
me know at *groth@physics.princeton.edu*.

You may occasionally get a file not found error if I've put in the link, but haven't installed to the actual file yet.
