Academic Honesty:
All violations of the Georgia Tech Honor Code will be handled by referring the case directly to the Dean
of Students for investigation and penalties. Past infractions have included cheating on tests, copying lab
results, copying homework, and forging TA signatures. Additionally, you are not permitted to share your
clicker with any other student for the sake of completing any assignment. Doing so will be considered
a violation of the Georgia Tech Honor Code and be handled accordingly. As a reminder to students,
violations of the Honor Code can be met with minimum drop of one letter grade in their final course
grade and potentially academic probation.
Main Lectures (in Howey (Physics): Section A (L3), Section B(L2)):
Main lectures are held twice a week unless otherwise announced. See the weekly lecture schedule at
the class website on t-square. The purpose of main lectures are to inform students of the broad view
on topics that are being covered each week. Ideally, the main lectures should motivate each topic and
introduce the major components involved in developing a deeper understanding of the course material.
Attendance is expected and a critical part of performing well in the course. It is important that you come
to class prepared and pay attention and answer questions during the lecture.
Recitations (in VL361):
Recitations are held each week unless otherwise announced. See the weekly recitation schedule at the
class website on t-square. The purpose of recitation is to answer questions and facilitate a deeper and
more personal interaction with a professor on the content of the course. Ideally, recitations are student
led in that the instructor functions to assist students in the areas they feel they are most challenged.
Attendance is expected at each recitation and the instructors will be responsible for 5% of your grade
based on ACTIVE participation which includes, but is not limited to, regular attendance, asking and
answering questions in class, and contributing to the overall learning experience of the recitation session.
Laboratory (in 2440 Klaus):
The labs will meet once per week unless otherwise announced. There is no lab the first week of classes
(week of 8/22-8/26). See the lab schedule on t-square. You can bring your own laptop to lab, if you like,
as long you have already installed all of the necessary software; otherwise you should use the desktop
machines. The laboratory explores hands-on applications of the course concepts using M ATLAB. It is a
critical component of the course,and for this reason is MANDATORY: Any student who does not turn in
a signed worksheet during their assigned lab time will receive an F for the course. It is imperative that
you come to lab prepared: read the lab description, print the lab description and sign-off sheet,and work
through as much of each exercise as possible. If you come to lab unprepared you will not be able to finish
in time.
Excused Absences:
NO make-up exams, labs, hw, or in-class exercises will be given. If you are excused from an exam, the
next one will count double towards your score. If you must miss an exam, lab, class, or HW for some
grave illness or other reason beyond your control, you must send an e-mail immediately to Prof. Moore
or Prof. Lanterman, and also to your lab TA if your absence involves missing a lab. A written letter from
a doctor or other official will be required for documentation. The written excuse must be given to Prof.
Moore or Prof. Lanterman immediately upon return to GT, no later than 3 days after the event.
Homework:
Written homework will be assigned (approximately) weekly and will be due at the beginning of your
assigned recitation period (unless otherwise specified in class). For help, consult the class website and the
CD-ROM for many examples of solved problems. Solutions will be posted immediately. Late homeworks
will not be accepted. In addition to written homeworks, we will also be using the intelligent tutoring
system (ITS) (http://its.vip.gatech.edu/faq/), which is an online system that reinforces
your understanding of basic concepts. There will be approximately 10-12 written homework assignments
and 10-12 online ITS assignments that count equally. The lowest of these 20-24 scores will be dropped,
so that your homework grade will be based on the top 19-23 scores that remain.
Office of Disability Services
If you are a student registered with the Office of Disability Services (ODS), please make sure the appropriate forms and paperwork are completed with both your main lecturer (Section A or B) and your
recitation professor within the first week of classes. The instructors will abide by all accommodations
required by ODS. The schedule for exams is posted in the syllabus and any potential modifications or
changes will be made with at least one week’s notice. It is the responsibility of the student to properly
arrange test accommodations for each exam with ODS in sufficient time to guarantee space for exam
administration. ALL exam accommodations must be handled through ODS. If the student does not
register accommodations with ODS for the taking of an exam, then they will have to take the exam at the
normally scheduled times without any additional accommodation unless the instructor is given specific
directive from ODS on the students behalf due to a mitigating circumstance.
Office Hours:
At this time of writing, times and locations for office hours are still being worked out; this information
will be posted on the class website. You are welcome to go to anyone’s office hours.
Student Collaboration:
Students are encouraged to study together for the exam and to openly discuss course topics. However,
each assignment that is turned in must reflect the work of the individual student. No copying of work
from other students in (or out) of this class is allowed and such activity would represent a violation of the
honor code. If you are not certain of the nature of a student collaboration you are involved in, please feel
free to contact either Prof. Moore or Prof. Lanterman to clarify.
Teacher Commitment:
All of the instructor’s and graduate teaching assistants commit to dedicating our time and energy to ensure
that you have a productive learning environment for this course.
Student Commitment:
As the student, you agree to commit your time and energy to learn the material by completing all assignments in a timely manner, attending all class sessions, and seeking help when you require it.
