The Summer '09 Physics 2005 homepage
Dear Class,
So i hope you dont hate physics... or at least I tried to use the demos
and create powerpoints to show you a world repleat with the concepts
which can seem far removed from reality when you learn them in class. I
encourage you to watch a nova-special or two to increase your ability
to marvel at the physical world we are trying to uncover with research.
On a more practical note, I hope that you learned a few things
about: dealing with a frustrating subject, taking some pride in the
work you turn in, learning to be careful and checking what you do, and
a myriad of other things which you can use in any field. Who
knows if I succeeded at these tasks or not, it is only my hope that
there was something of value you take away from it, be it life skills
or the ability to take interest in technology and science.
The final grades formula turned out to be fairly simple: the exams were
1/3, your homework another 1/3, and because the quiz average
numerically was 44% that's where i added the attendance and your term
paper for the final 1/3. The final grade inflation was a rigid
shift of 5.7% to everyone's score. This was done so that the class
average was 80%, and the high score was 100%. Letter grades are
assigned in the standard 10-point per grade scale (90-100=A, etc), only
i didn't give out C-. If you made the cut to a C i just said C, since I
know for many of you this small percentage difference causes life
changes. In a similar vein, there are no F's, only D+s. If you
have a grade that low, it's because you consistently averaged that, i
spent a fair amount of time today looking for reasons to not give out
D's, like acing the final, which is to say that if you got a D,
it is likely that you did at-best average on the final, and your other
work was sub-par too consistently for my formulae to curve you out of
the hole. I know that's disappointing, but I cant grade everyone
differently. No grades were lowered. Everyone got a free 1/2
letter grade, and the only fiddling is how the scores from your work
are mixed. The class averages were: about 72% on tests overall,
80% on homework, 44% on quizzes (hence where the free points went).
email me for anything, although as I mentioned a lot in class, I'm at
UCSB working for a while, so I'm fairly busy, and you were supposed to
take care of issues before I left. These grades are 'final,' for that
reason.
Greg
un-curved exam results, im working on your final grades and whatnot.
it'll be in the university system as soon as that's all done.

Dear students,
please be aware that about 1/3 of the final is new material, the other
stuff is as balanced a mix as i could invent of old material without
having a very very long exam. it's cumulative and about 0 of the
questions are new to you, so if you study your homework/tests/quizzes
then you should be not just good, but golden.
with love,
your instructor
old exams (please note, im attaching the files i have on me, so the
questions are all here for you to practice, but the answers on this
particular version are not necessarily proof read)
exam1
exam 2
current running grades total, without any special modifications like
dropped scores....i cant post your student ID info so you have to email
me to find you, but a good way to ID yourself is to add your two test
scores and search along the test-axis..the axes are (x,y)=(hmwrk,
test). dont worry, there is one fake-point at (1,1) for perfect.
PBS is cool:

The last homework (due weds)
chapter 27 problems 3,7,10,9
chapter 28 Q8, problems 5,7,13,15
make sure to read 28.6
Dear Class,
The results are in. Good job again. No really, good job, the vast
majority of you knew what you were doing and showed up average or above
average (histogram below). On this (longer) test, the mean was 9.5 with
a standard deviation of about 3. If I were below a 6, I would be
worried...some of you lower scores out there also have very poor
attendance records. I found one error which I am in the process
of correcting (two wires, 10 amps, 10cm away= none of the
above). We move onto diffraction and hopefully some modern
physics, term papers are due next week.
see you in class,
me

test 2 information Monday
July 20th in class.
(I will be absent on the friday before that, but we will review for
most of the previous classes)
material: through chapter 22-26, same format as last time so that's
about 3 or 4 questions on each chapter
practice exams link:
old
tests
term paper information due
July 27th in class
select a topic which interests you relevant to this course's material,
approve it with me (send a mail to my gmail), write 2-5 pages on the
physics, include citations to your references.
some ideas:
the cosmic microwave background radiation, metamaterials, any
electronics we didnt cover: semiconductors, op-amps, solar power,
diodes, LCDs, lasers, computers ....(huge list here), Medical
Technology (MRI, PET scans, CAT scans....), early experiments on atomic
physics, nuclear power, modern particle physics, exotic states of
matter, superconductors, ....
chapter 26 homework instead
of the anticipated quiz, i would prefer you to do homework on chapter 26
because of the impending test. Due 15th July
chapter 26: 1, 3, 7, 19, 20, 23, 25, 32, 33, 37
Homework due friday (july 10th)

P 1,2,3,4,6,7,8
suggested quiz problems for friday (3 July)
chapter 24 Q5, P1,3,10,14,19, 33,40, 47
(study RL, RC, RLC=radio, resonance, know what impedance is,
RMS, transformers)
PLEASE NOTE: GRB might not be here on friday 17 July. Stay tuned to see
if we have a short class or no class, i have to be at the airport.
I think it's ok to have class from 930-1030 possibly, but i need to
make the plane.
HOMEWORK (due monday, after the break)
chapter 22: 3,9,12,17,18,20

as you can see from the histogram, there is a large lump right around
10. So congratulations! i am rather happy with that result, it means
many of you learned most of the stuff. good job. i am not allowed
to post your grades publically (for some reason), so you will have to
email me for your grade (grboyd2005 at g mail ). As i am travelling,
you may or may not get it for a week. btw, the numerical average is
somewhere between and 8-9 with a standard deviation of 2ish.
test update
I am going to proceed with the schedule as written since
electric-anything comes to a logical completion before we start
magnetism.
The test will cover up to section
21.6. So the test will cover chapters 19, 20, and most of 21.
random unsolicited pointers on how to do well:
Monday and wednesday next week im just going to do example problems in
class since we have covered all the material once.
A good rule of thumb about studying is the following: for every hour of
lecture you probably need to put in about 2 hours of outside work. This
amounts to one 6-hour evening a week (not too bad). To practice
make sure you can solve all the homework and quiz problems.
I will also assign some extra circuit-practice problems from chapter 21
to get used to using kirchhoff's rules. Another thing i suggest to make
sure you've ingested everything is to create your own set of notes by
rereading the textbook. The nice thing about this is that if you go to
the library and get a different book, you can have every idea explained
to you twice in different language.

update may 26th:
Next homework due monday (june
1)
Chapter 20 35,36,37,45,46,50
Chapter 21 3,5,12,14
because of the performance on the first quiz there is an outside
possibility that i will postpone your exam in order to review some of
the material. be forewarned.
your quiz: per your
request i came up with a list of suggested problems to help study:
chapter 20: Q 4, 10 Problems: 35-38, 12, 13, 20, 31-33
chapter 19: your previous homework and 41,42, 26,27, 48
good luck friday!
update 19 May:
1) there will be an in class quiz on friday, you need to know all
of 19, and whatever i finish covering may 20th.
so very basic current, resistors, and capacitors.
also, this is the HITT registration if yours doesnt work yet. you
are expected to have it working by now, if not please talk to john mocko
http://www.phys.ufl.edu/~hitt/
