PS 250 - Physics III for Engineers
Embry-Riddle University
Fall 2019
M. Anthony Reynolds

The thinking of a scientist differs from that of a student.  The student wants to know facts: numbers, dates, results, things which might appear on the final exam.  How old is the universe? How distant is the Moon? How hot is the Sun's visible face? All these can be dug out of textbooks and encyclopedias, but they alone tell next to nothing about the science.  A scientist instead asks, What is the evidence?
- David Stern

Problems are the cutting edge that distinguishes between success and failure. Problems call forth our courage and our wisdom; indeed, they create our courage and our wisdom. It is only because of our problems that we grow mentally and spiritually. When we desire to encourage the growth of the human spirit, we challenge and encourage the human capacity to solve problems, just as in school we deliberately set problems for our children to solve. It is through the pain of confronting problems that we learn.
 - Morgan Scott Peck


INFORMATION

This is the third semester of a three-semester, calculus-based physics sequence.  The required prerequisites are PS 150 and PS 160 - Physics I and II for Engineers, as well as MA 241 and MA 242.  We will cover electric fields and magnetic fields, Gauss's law, electric potential, capacitors, Ohm's law, Kirchoff's laws, Ampere's law, Faraday's law, Lenz's law, Maxwell's equations, and selected topics from modern physics.

Listening to lectures is not enough.  All processes of learning are somehow connected to active participation, and the learning of physics is no exception.  Therefore, it is imperative that you work diligently at your own desk.  However, this does not mean that you should only work alone.  I encourage you to form study groups and collaborate with your classmates.



HOMEWORK

Practice at problem solving is an important part of learning physics, especially for engineers.  I suggest that you work as many problems as possible.
