Solutions to the final are now posted. The final had 171 points. The mean was 93, the standard deviation was 32. The high score was 169; the third highest was 131; the low was 37. Grade distribution: 2 A+, 5 A, 6 A-, 4 B+, 3 B, 2 B-, 4 C+, 4 C, 2 C-, 1 D. The grade boundaries were drawn in gaps of the cumulative score for the course.
Best wishes for the holidays. Have a happy and relaxing break. Best wishes for the new semester and year.
Solutions to last year's final are now posted on the password-protected page.
A list of themes and highlights has been posted and linked below near the study guides; it will likely be updated. In response to a student inquiry, note that there will be nothing on sections 5.5 and 5.6, except perhaps something simple about changes in boiling and freezing points. There could be something about the Ising model, the mean-field solution to it and its analogy to the paramagnet. (pp. 339-345).
The formula sheet was updated a little and a couple errors fixed. The formula sheet was again updated in response to class input, with formulas for dimer rotor energies, chemical potential from F, total energy density of photon gas, and Tc of BEC.
Solutions to Problem Set #10 are now posted.
Last year's final is now linked below; the formula sheet is updated modestly .
Solutions to Quiz 3 have been posted. Total points possible: 28; mean: 17.5; std. dev.: 5.3
Note that the TA is available on Thursdays and Fridays after 3:00 (see office hours below) in case of questions about grading of homework (or other issues). Comments on the quiz on Tuesday, Oct. 8: The questions will be multiple choice or circle the correct answers. The quiz will be allotted about 15 minutes, at the end of class. It will cover the 3 models studied by Schroeder, laws of thermodynamics, numbers of configurations and related probabilities and entropy. It will include energy, temperature, entropy, pressure, heat, work (but not enthalpy). There will be no formula sheet. It is intended more to assess how well you are keeping up than to grade you.
