General notes on homework assignments

(1) Show all work in order to get credit

(2) Use full precision for fundamental constants and masses - the data should dictate the final precision and not your rounding of known constants

(3) All final answers should have appropriate units noted

(4) Be aware of significant figures in your final result (but don't go crazy on them)

(5) No hand-drawn graphs!  Please minimize the use of your calculator's solver button as well as Wolfram Alpha

Additional Resources


Academic Integrity: I encourage you to work with classmates on homework assignments. However, each student must turn in original work. No copying will be accepted (this includes copying from textbooks or prior semester homeworks). Students who violate WSU’s Policy on Academic Integrity will receive an F as a final grade in this course.

Students with Disabilities:
Reasonable accommodations are available for students with a documented disability. If you have a disability and may need accommodations to fully participate in this class, please visit the Access Center. All accommodations MUST be approved through them (Washington Building, Room 217). Please stop by or call them at 509-335-3417 to make an appointment with a disability specialist http://accesscenter.wsu.edu.

Course description: An introductory course in statistical mechanics.

Class meetings: Tuesday and Thursday 10:30-11:55 am in 269 Lauritsen, starting March 29, 2016.

Feedback: If you want to send a comment about the course, click here.

Instructor:

John Preskill, preskill(at)caltech(dot)edu, 206 Annenberg.

Recitation leaders:

Kung-Yi Su, ksu(at)caltech(dot)edu, Wednesday 6:30pm-8:30pm in 11 Downs.

Brenden Roberts, broberts(at)caltech(dot)edu, Recitations Monday 6:30pm-7:30pm in 11 Downs. Office hours Wednesday 2:30pm-3:30pm in 240 Lauritsen.

Graders:
Vijay Varma, vvarma(at)caltech(dot)edu, Assignments 1, 3, 5, 7.

MykytaHulko, mhulko(at)caltech(dot)edu, Assignments 2, 4, 6, 8.

Textbook: Thermal Physics (2nd edition) by Charles Kittel and Herbert Kroemer

We will cover most of the first 10 chapters of Kittel and Kroemer, plus part of Chapter 14 and some supplementary material.

Grading: Grades will be based on weekly problem sets (40%), a midterm (20%), and a final exam (40%).

Homework: Problem sets will be posted on this page on Thursday, and will be due in the Physics 12c IN-box by the East Bridge mailboxes at 8:00 pm the following Thursday. Graded homework will be returned to the Physics 12c OUT-box in 264 Lauritsen by the following Wednesday morning. Solution sets will be posted on this page.

Extensions:
--
Unexcused late homework will be accepted for half credit up until one week after the due date; there is no credit if your assignment is more than one week late.
-- If your homework will be late for a good reason, you may request an extension before the assignment is due by sending email to that week’s grader.
-- One extension, for up to one week, is allowed without question (your silver bullet). Please put a note at the top of your problem set indicating that you are using your silver bullet.

Honor Code: Discussion with others is encouraged, but the work you hand in must be your own. In particular, do not use homework solutions from previous years or exams and exam solutions from previous years. Please write legibly. You may use a symbolic manipulation tool such as Mathematica or MATLAB for doing computations on homework or exams, though this probably won’t be necessary.

Twitter: I’ll attempt to summarize each lecture in 140 characters or less. See the #Ph12c tweets.

Exams: 
Midterm Exam, Covers all material through Problem Set 4. Solutions
54 exams were received. The median was 83, the mean was 82, the standard deviation was 14. 12 students scored 95 or above, and 4 scored 100.

Final Exam, due June 10. Covers all material in the course.Solutions
52 exams were received. The median was 82 and the mean was 80. 11 students scored in the 90s, and the highest score was 97.

Grades: 
Final grades were determined using the formula Grade = 0.4(Homework) + 0.2(Midterm) + 0.4(Final).
The median final grade was 86 and the mean was 84.
The ranges for letter grades were:

A+95-100
A90-94
A-85-89
B+80-84
B75-79
B-55-74

The distribution of letter grades for the course was:
8 A+, 14 A, 7 A-, 9 B+, 9 B, 5 B- (52 total)

I hope you enjoyed Ph 12c and learned a lot. If you have not already done so, please review the course by responding to the TQFR survey. Your feedback is very helpful, especially if you have suggestions for improving the course. In particular, I would like to know: whether you liked the book, whether the online notes and videos were useful, whether the lectures were too much like the book, whether the homework helped you to learn, whether the recitations were effective, whether the exams were reasonable and the grading was fair... Or whatever else you think is relevant.

One other thing … A few of you mentioned in the TQFR comments that the Sam Elder notes contain serious typographical errors. It would be helpful if someone could point out the errors, either in an email to me, or by filling out the anonymous comment form on this page.

Thanks, and have a great summer.
