Lecture Instructor's Comments
Welcome to PHYS 123a, the 3rd of a three-quarter
physics courses for physics and engineering majors. You should find
course challenging and stimulating, though perhaps it will not fit your
preconceptions of what a university physics course should be. I hope
you also find it to be interesting and enjoyable. Have a great quarter!
The course design is a cooperative effort of many faculty, each
is deeply concerned with providing the most effective learning
for every student. Each element of the course (lecture, lab and
is essential to your mastery of physics. The three elements are
coordinated, but are not necessarily synchronized. Research has shown
presenting material in cycles, so that the same topic is approached
than once from different viewpoints, is a very effective means of
deeper understanding and long-term retention of ideas.
You are strongly encouraged to visit with me regularly during
by appointment, by e-mail, by phone, etc. Get used to the idea of
the Professor outside of class during the quarter; it will pay off for
you in many ways as the years go by! This will not happen unless YOU
the initiative, and now is a great time to start.
Memorization of material is not particularly helpful in this
goal in this class should be to understand how each new topic is
to all of the previous material, and how the concepts, rules and
can be applied to solve real-world problems. Never let anything go by
you do not understand. Generally, ask questions immediately. If it is
to interrupt, make a quick note to yourself and inquire later.
- Each quarter, the UW Office of Educational Assessment conducts
of undergraduate courses. For many years, the PHYS121-2-3 courses have
been among the courses reportedly requiring the most hours of work per
week outside of class. A typical course will show a span from 5 hours
week to 20 hours of study per week outside of class, probably including
some time spent on PHYS123Z. Many courses claim to require at least
hours outside of class for each hour in class; PHYS123/123Z delivers.
- Note that MATH 126 : Calculus III is a
prerequisite/corequisite for this class. However, there is ongoing
as to whether MATH124 should be a strict prerequisite rather than a
for PHYS121. It is the opinion of many instructors that students who
already completed MATH125 are at a considerable advantage in PHYS122.
although it is possible to take the PHYS121-3 and MATH124-6 as simple
(i.e. P121 _with_ M124, etc.), students who have no prior experience
either calculus or physics should seriously consider getting 'one
ahead' in the MATH124-6 sequence with respect to the PHYS121-3 sequence.
- Be aware that many technical majors have a minimum grade
a core of lower-division technical classes including the PHYS121-2-3
Therefore, each student is strongly urged to discuss
entry requirements with their undergraduate or departmental advisors,
plan their course loads accordingly. The course grading policy is
Concurrent enrollment in PHYS123 and PHYS123Z is mandatory; students
will receive a combined grade for lecture, tutorial and lab. The final
course grade is based on the best two of three midterms, the final
the Tycho lecture HW, tutorial participation and HW,
lecture exercises (using the new infrared response system), and
Lab participation and reports. A summary of the grading policy for this
course may be found in the 12X Grading Policy Statement.
However, the lecture instructor may adjust individual final grades
by no more than 0.2 grade points (about 5 % out of 4.0 possible) based
on records from the lecture infrared response system and/or the
homework related to the lecture. All percentages discussed in the
statement and in the summary below are used to determine your raw
before this adjustment is applied.
- Midterm exams: There will be three closed-book midterm
midterm will emphasize recent material, but may include questions
with topics from far earlier in the course. The exams will include both
multiple choice and essay-style questions. Only the best two of three
of the z-score [(your score - class average) / (std deviation)] will
toward the final course grade. Your lowest midterm score (relative to
mean) will be dropped. After correcting for different average scores on
different midterms, the midterms will contribute 40% to your final raw
grade. You are permitted to bring one 8.5"x11" page of notes (front
to each midterm. Calculators are permitted. Cell phones, radios, etc.
are not permitted.

outside professional, service, or career commitments (i.e. military
ROTC, professional conference presentation, NCAA sports, etc.)
exactly with the exam dates must contact the intructor early in the
quarter to establish alternate examination procedures. Students who
miss an exam without making prior arrangements with the lecture
will drop that exam score. Illness with a doctor's affadavit may be submitted for
exceptions to this rule. Except for extreme circumstances, a final
of 0.0 may be assigned to any student who misses two midterm exams.
- Final Exam: A two-hour closed-book comprehensive final

10:50 to 11:50 am. This examination will cover material from the entire

may return an exam for regrading. To do so, you must resubmit the
no later than at the beginning of the lecture following the one in

return. You must write a brief note on the front page
attached to the front page of the exam explaining the possible error in
the grading. Do not make *any* changes or marks on the other pages

- Labs and Tutorials: Grading policies will be explained
and tutorial section. Please note that grades for lab and tutorial form
a significant percentage of your overall grade for the course. Also, completion
of most of the lab and tutorial work is required in order to
the course. For example, if you complete fewer than six labs during
the quarter, and do not make up the work, your grade for the entire
will be 0.0 ! Even completing six of the eight labs will reduce your
significantly. Do not skip these important activities!
Your responsibilty: Check your
Tycho system every week or two and report any problems to both the
instructor and the relevant TAs (and/or lab/tutorial faculty)
Lab, tutorial and exam grades should be recorded for your review within
one week from the date that papers are submitted for grading. Tycho
grades should be recorded within 24 hours of submission. Grading problems that are
in a timely fashion will be investigated and, if action is warranted,
lecture, lab and tutorial instructors may choose to ignore grading
that are not reported in a timely fashion.
- Lecture homework will be assigned and collected weekly through

The Physics Study Center
Students are encouraged to gather and work cooperatively in small
in the Physics Study Center located in room AM018 of PAB. (to reach the
Physics Study Center, go down the stairs that circle behind the
pendulum and proceed toward the end of the hall). Teaching assistants
be available for consultation during many portions of the day if your
group needs assistance, but staffing levels will not support much
individual attention. The Study Center is staffed from approximately
9:30am to 4:30pm on weekdays.
