**Instructor: **Professor Yongsheng Gao

Office: Room 4A, Fondren Science Hall

Telephone: 214-768-2819

**NOTICE: First lecture starts on August 24, 2004.**

**Office Hours:** Tuesday 3:00pm -- 5:00pm, or by appointment..

**Help Session:** There will be a help session scheduled every *Wednesday 5pm -- 6pm in Rm 110 Fondren Science by Anna Stelzenmuller*** (1st session meets on Aug. 25th) **.

**Textbook: ***"Physics for Scientists and Engineers" Vol. 2
*by Serway/Beichner 5th edition.

**Calculator: **A scientific calculator is a must. Necessary functions
are sin, cos, tan, exp, log, and roots, as well as the inverse operations.
(Note, you need not spend more than about $15 for this.).
**Bring your calculator to every class, especially when there is a
scheduled quiz/test/exam!**

**Prerequisites: **We shall assume a working knowledge of algebra
and trigonometry. A **limited** amount of calculus will be used.

**Quizzes: **There will be a 10 minute quiz **at the beginning of
class each THURSDAY**
(except when there is an exam scheduled). There are 10 quizzes. The lowest
2 grades will be dropped. **(Note, this includes all missed quizzes, doctors
appointments, and other emergencies.)** **No make up quiz** will be given
after the class quiz.

**Format of Quiz, Test and Final Exam: CLOSED BOOK. **
You are allowed to take ** ONE FORMULA SHEET (8.5"x11")**
with all the relevant formulas, constants and any other information you may
find useful. **Make sure ALL the relevant formulas and constants are on your
sheet (yes, you can write on both sides of your formula sheet).**
Calculator, Formula Sheet and pencil are all you need during quiz, test
and final exam.

**Grading: **The final course grade will be determined as follows.
Homework 5%, Quizzes 25%, Exams 30%, Final Exam (accumulative) 40%.

**Disability Accommodations: ** Students needing academic
accommodations for a disability must first contact Ms. Rebecca Marin,
Coordinator, Services for Students with Disabilities (214-768-4557) to
verify the disability and establish eligibility for accommodations.
They should then schedule an appointment with the professor to make
appropriate arrangements. (See University Policy No. 2.4.)

**Religious Observance: ** Religiously observant students wishing
to be absent on holidays that require missing class should notify their
professors in writing at the beginning of the semester, and should discuss
with them, in advance, acceptable ways of making up any work missed
because of the absence. (See University Policy No. 1.9.)

** Excused Absences for University Extracurricular Activities: **
tudents participating in an officially sanctioned, scheduled University
extracurricular activity should be given the opportunity to make up class
assignments or other graded assignments missed as a result of their
participation. It is the responsibility of the student to make
arrangements with the instructor prior to any missed scheduled examination
or other missed assignment for making up the work. (University Undergraduate
Catalogue)

**Homework: ** **Physics is not a spectator sport!**
Homework is assigned for each chapter. The homework solutions are posted
on the course website. I encourage you to work in a study group and to use
my office hours if you have difficulty.
It is **essential** that you can solve the homework problems
**independently**, and **fully understand the concepts and principles**
in those problems, as very similar problems will appear in quiz,
test and exam.

**Solutions: **
I remind you that many of the quiz and exam problems are very similar to
the homework. The solutions to the homework is provided as a convenience
to help you when you get stuck. You will find that it is not sufficient
to simply read through homework solution to understand the material.
**It is essential to struggle with the idea, and learn for yourself
how to solve the different types of problems.**
Consider the following analogy: If I ask you to drive to my house, you
would have significant difficulty because you would not know the proper
direction to travel, or the proper turns to make. But, if I told you to
follow me home, it would be trivial.
The same applies to the homework. It is trivial to follow me as I take
you through the problems and the examples. But when you are on your own
and I am not telling you what direction to go and you can not peek at the
homework solutions, it is far from trivial.
I encourage you to use the homework solutions as a tool; but, it is
not a substitute for you working out the solutions on your own. It takes
me about 2 hours to do a chapter of homework. I expect it should take you
2-3 times as long. (Maybe less, if you work in a group.)
Your final grade will depend on your ability to solve problems
independently. You can only earn a good grade by putting in time and work.
If you think you are close to understanding the material, but need just a
little more work, then come and see me during my office hours.

The goal of this course, beyond physics, is to give you the ability to approach complex problems, identify the important parts, ignore the irrelevant parts, and obtain a solution. It provide an opportunity for you to sharpen your analytical thinking skills. Whether you become a physicist, engineer, doctor, scientist, lawyer, architect, business executive, or whatever, your ability to deal with complex abstract problems will always be an asset.

While there will be many topics in physics I will not have time to cover, I hope to give you the skill that will enable you to understand these topics as you encounter them in your future studies. I hope that the knowledge and skills we cover in this course to be useful to you beyond the exam. I want you to become good critical and analytical thinkers. Not only to plug numbers into equations but able to develop new models and theories, to make qualified assumptions, and then use those models and assumptions to break new ground in science and technology.
