AND one of the following:
Data Reduction and Error
Analysis
for the Physical Sciences -
Phillip R. Bevington and D. Keith Robinson
(McGraw
Hill, Inc., 2003, ISBN 0-07-247227-8);
An Introduction to Error
Analysis:
The Study of Uncertainties in Physical Measurement – John R. Taylor (University Science
Books,
1997, ISBN 0-935702-75-X).
You will need TWO (2) lab
notebooks. Two
are required so that you can work in one notebook while the other is
being
graded. Acceptable lab notebooks should be 8.5" x 11", should be
bound (with spiral or book binding), and have
numbered,
quad-ruled pages. Pages should be permanent, not perforated for
tear-out. If you have many pages left in a lab notebook from
another class such as Phys 375, you may use that one.
LECTURES:
For approximately the first half to the semester there will be a 1-hour
lecture
from 12:00 – 1:00 PM in Rm. 3112 on Wednesdays. We will cover error
analysis,
laboratory measurement techniques and any other material germane to the
course.
You will be responsible for understanding the material presented in
lecture
and, when appropriate, expected to include some of this material in
your
notebook reports and in your final formal report. If you miss a lecture
you are
responsible for finding out from a classmate what was covered.
During the
second half of the course, the lecture slot will be used for 12-minute
presentations by students. Attendance at talks is
mandatory! Without a valid excuse approved by
your instructure, you will not pass the
course if you
do not attend all presentations. You are responsible for knowing the
dates of
the presentations, which are subject to change!
EXPERIMENTS:
In order to pass the course, 6 units of work must be completed, which
will
typically consist of 4 to 6 experiments. Failure to complete
all 6
units will result in failing
the
class; completion is defined as performing the lab and turning a lab
notebook
to be graded. Each student is required to
work on the
experiments entirely by her/himself. At the completion of each
experiment, you
will need to hand in the laboratory notebook for grading. This means
that it
will be necessary to have at least 2
laboratory notebooks in order to have one available while the other is
being
graded. Every attempt will be made to grade your experiments promptly
so that
you will be able to improve your next report before handing it in. The
notebook
reports are meant to be your notes and documentation of your work in
the lab,
and are not meant to be a formal write-up. (Please refer to the
laboratory
manual for more information on the notebooks.)
Your first experiment should be a one-unit experiment. (in order to total six units, you must therefore complete at least one other one-unit experiment). You may do either zero, one, or two two-unit experiments.
SCHEDULING
EXPERIMENTS:
There will be an online sign-up sheet that can be accessed from any
computer
with an internet connection or from the computer in Rm. 3210. The url is http://www.physics.umd.edu/cgi-script/courses/p405.pl
You must request time each week to perform your experiments. Time
slots
are available in ½-day periods. In order to save your
experimental setup,
you must sign up for two consecutive periods. Also, please
dismantle your
setup when you have completed your data taking and remove your data
from the local computer's hard drive.
Prior to carrying out an experiment, you are required to complete the preparatory questions at the start of the experiment. There is a spot on the course website for you to electronically submit the prep questions, or you can hand them in on a piece of paper at the beginning of the class period in which they are due. You must have the prep questions examined and initialed by either the instructor or the TA before you begin the experiment.
DUE
DATES FOR THE NOTEBOOK
REPORTS:
Notebook reports are due according to the schedule shown in the syllabus. There is a 1-point penalty per weekday for late reports!
FORMAL
REPORT:
One of the 4 to 6 experiments is to be rewritten as a formal report and
is to
be turned in by Friday, Dec 12, 2008. Please refer to the laboratory
manual and
the information here
for the format of the formal report.
ORAL PRESENTATIONS:
Each student will be expected to give one 12-minute talk on an
experiment of
his or her choice -- if you clear it with me first, you may also talk
about your research if you've been working with a research group.
The talks will be followed by questions from
the
instructor, the TA, and the other students.
HOMEWORK:
Several times during the semester a short set of homework
problems will
be assigned. The purpose of these assignments is to review and
strengthen your
understanding of the type of error analysis you will be performing in
your
laboratories, as well as get some experience with common experimental
issues.

VALID EXCUSES:
If you have a valid excuse for missing a due date for a notebook report
or a 12
minute talk (e.g., you will be having an operation) see me to make
alternate
arrangements, beforehand if at all possible. Ex post facto (after the
fact)
excuses will require validation and may not be acceptable. You must
speak
to me. Your TA does not have the authority to excuse you from any
required
class activity.
ACADEMIC
DISHONESTY
(CHEATING):
Academic dishonesty is a serious
offense
that may result in suspension or expulsion from the university. In
addition to any
other action taken, the normal sanction is a grade of "XF", denoting
"failure due to academic dishonesty," and will normally be recorded
on the transcript of the offending student. Remember, you are required
to
perform all experiments, analysis, and write-up by yourself. It is OK
to
discuss the experiments with other students but you must
do the
work.
TIPS
FOR DOING WELL:
Don't fall behind! Don't wait until the last day to do an
experiment!
Read the lab manual carefully
before
attempting an experiment.
Answer the preparatory questions in your notebook and have them checked
by the
professor or TA before you begin the experiment.
Keep a complete log for the experiment
including
experimental diagrams of measurement configurations actually used to
obtain
data, results, estimates of various errors and limitations to the
measurements,
analysis used to obtain final results and a proper estimate of all
errors
including systematic errors as well as statistical errors.
Show clearly the reasoning that you used to arrive at various
conclusions. If
your experimental result does not agree with the known or accepted
values, your
reasoning may be the only clue that the TA or the instructor has as to
where
you, or the experimental apparatus, went wrong.
Additional information, a list
of
experiments and more detailed help can be found at the course website.

Final Report due Friday |
*All subsequent prelab
questions must be completed and checked (initialed) by the TA or the
instructor
before you start your lab. The lab notebook due dates correspond to
1-unit
labs. You will have twice as long to complete 2-unit labs. The due
dates
correspond to 12:00 noon unless otherwise specified.
GRADING OF NOTEBOOKS:
Your lab notebook should give a complete description of how you did
your
experiment and how you analyzed your data. Another person should
be able
to take your notebook and duplicate your experiment.
For the notebook reports you
must do the
following:
1. Write in a real lab notebook: notebook
should be
quad ruled, with numbered pages.
2. Write in ink. If you make a mistake, draw
one line
through it - don't erase it, scratch over it, or use white-out.
3. Staple/past/tape all graphs and analysis in notebook. Label axes. Include any formulas,
derivations,
etc. needed to understand your graph.
4. Give a brief description of theory behind experiment.
5. Provide the actual circuit diagram you used to do the experiment.
6. Provide a clear description of the procedure used to take data.
7. Provide the units of all numbers.
8. Provide and explain your estimate of the random and systematic
errors in all
important quantities effecting your final result. Must use proper error
analysis techniques.
9. Pay attention to significant figures.
10. Analyze your data. Write down the methods you used. If you
use Mathematica,
do not simply paste your Mathematica
notebook
into your lab notebook - write down in your lab notebook your
analysis
steps. Compare statistical error with random error (reduced χ2).
Discuss.
11. Quote your results with final total error (including systematic
errors).
12. When appropriate, compare your answer to the expected value and
discuss
discrepancies.
13. Be sure you have answered all the questions asked for in the lab
manual,
including discussion questions at end
of unit.
14. Be sure you have done all the parts of the experiments that you
were asked
to do.
