Foundations of Physics II
Spring Quarter 2005: Thermal physics
MWF at 11:00 in Pacific 30.
This is the third quarter of a three quarter course. Fall quarter was
devoted to oscillations and waves. During winter quarter the course
covered more about oscillations and waves, then turned to thermal
physics. In spring quarter, we will continue with thermal physics. The
goal is to understand the Second Law of Thermodynamics and also to
learn something about the practical applications of thermodynamics. We
will also learn how to use computer tools that are useful for this and
other topics.
The webpage for
Physics 351 is still available, as is the webpage for Physics
352.
The final exam (2nd midterm) key is posted here.
The exam score results (average=68) are posted here,

Good job, everyone! Have a great summer.

Well, what do you get when you cross an elephant and a mountain
climber? Still stumped?
Instructor:
Text:
- An Introduction to Thermal Physics, Daniel V. Schroeder.
- Also useful:
Physics for Scientists and Engineers, Paul A. Tipler (4th Ed.).

Optional Paper and Presentation (replaces second midterm exam)
The paper should involve an original calculation or possibly an experiment
that investigates or illustrates something in thermal or statistical
physics. A computer calculation would be appropriate, but an analytical
calculation is fine also. Later this term we will be doing some computer
simulations of the Ising model for a magnetic solid, but problems on heat
conduction are also interesting and instructive. If you want to do a
calculation, try to find a 1-dimensional model situation that is relevant
and of interest!
The papers are to be done collaboratively by groups of between two and
four students, with each author assuming equal responsibility for the
content. I will assign a grade to each paper, which will count for each
author of the paper. Thus this will be a team effort. Each group should
choose a subject of interest to it.
A small group is often much more effective than a single person for
getting something creative done, but it may take some practice to learn
how to operate in a small group. If a group is having trouble operating
effectively, I can attempt to offer advice. In the event that a group
breaks up, I could accept papers from subgroups or individuals.
Groups should form themselves and propose a subject by April 28. Each
group should turn in a draft paper by June 2. June 7 (if needed) and June
9 are reserved for in-class presentations of the paper content by the
submitting group. The final paper is due on Friday, June 9.
Grading:
The homework assignments will count for 30% of the course grade. There
will be two midterm exams, which each count for 35% of the course grade.
The second midterm exam will be held at the time of the final exam
and may be replaced by the paper.
