Fall 2002

**Instructor: **Professor Yongsheng Gao

Office: Room 4A, Fondren Science Hall

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

**Help Session:** There will be a help session scheduled every *Wednesday Evening 5pm -- 6pm in Rm 123 Fondren Science by Alonso Gutierrez*** (1st session meets on Aug. 28, Wednesday) **.

**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 a test 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.

**Grading: **The final course grade will be determined as follows.
Homework 5%, Quizzes 25%, Tests 30% (1st test: 15%, 2nd test: 10%, 3rd test:
5%), Final Exam (accumulative) 40%.

**Disability Accommodations: ** If you need academic accommodations
for a disability, you must first contact Ms. Rebecca Marin, Coordinator,
Services for Students with Disabilities (214-768-4563) to verify the
disability and establish eligibility for accommodations. Then you should
schedule an appointment with the professor to make appropriate
arrangements.

**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 directly from
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.
