to the 121C final exam will not be posted until after 121A, 121B and
121D have taken theirs (sometime Thursday).
Multiple choice scores for the final are now uploaded. A few
incorrect numbers were uploaded for a couple of hours. That
has now been fixed.
meets this week as usual for Simple Harmonic Motion. Lab is
make-up only. You must sign up in advance for a make-up lab or
risk not having the appropriate equipment set up. Only one lab
may be made up in a single 3 hour session.

11/20 As we
approach the end of the quarter, check with your lab and tutorial TAs
to make sure you agree on what work you have completed or missed.
11/20 If you
have not yet registered your clicker, please do so now at this web site. A list of clicker
numbers that have points associated with them, but no UWNetID, as well
as a list of UWNetIDs for which there is no clicker number, is here.

clicker questions through Nov 19 lecture is posted here.

couple we didn't have time for in class) are posted here.
on Tycho problem with mass spinning around a rod, attached with two
strings: I recently learned that part of the issue with that problem
was that about 10% of you got random numbers that generated an
unphysical result, with the tension in the lower string going
negative. If you find this to be the case during your review,
blame Tycho and not your knowledge of physics. The problem was
extra credit, so it won't affect your grade. You should, however,
understand it before the midterm.

6, and posted on Tycho.
There are nearly 50 clickers that have been used at least once, but not
registered. To get
credit for your clicker points, you must register your clicker here. If you changed clickers after
October 6, then you should register your new clicker and also send
Prof. Olmstead an email with your old clicker number in it so she can
connect both with your name -- the registration system only keeps track
of your most recent registration.
Supplemental HW grades will only be posted on WebAssign.

to be able to read your name, bring a sample of your handwriting to
Susan to claim your paper.

scantron "bubble sheet" to the midterm, as well as a number 2 pencil
with which to fill it out. You may also bring one page of notes
and a calculator.
10/9 Your best
8 out of 10 will count on this week's Tycho HW since we didn't get to
circular motion with forces or friction by Wednesday's lecture.
You can thus skip those two problems with no loss of credit. If
you did them already, they will count as extra credit against a future

issues: The bookstore is on back-order for clickers, due
in "early October". For a clicker to work in A102, it needs to
say "H-ITT" on it. It does not need to be registered to work
(just before the end of the quarter so I can assign your clicker's
points to you). I'm not sure if the same clickers work in
chemistry and/or biology. Those of you with old-style (infra-red,
not radio frequency) clickers will need to have fresh batteries and aim
your clicker at one of the receivers up near the ceiling that are
scattered about the sides of the lecture hall. Those of you with
new-style (radio frequency) clickers will need to set your frequency
while in the classroom with the computer listening for your
clicker. We'll do that in class on Friday. The procedure

received an email announcing this survey. It
will help Prof. Olmstead structure the class to your needs. It
also allows her to collect statistics on the interconnections between
math/physics preparation and class performance. So far, she has
found that coming to class (as measured by number of clicker questions
answered) is a far better predictor of final grade than any math or
high school physics class.

your lab or

time schedule to see where there are open spots. Check often,
since spots may open up as other people change sections or drop the
course; note that the UW website is only updated every night at
midnight, so spaces may open up during the day as other students change
their schedules. If you really need to get into a closed section,
