Clickers
We will use i>clickers for various kinds of assessment: pop quizzes, homework quizzes, in class discussion, etc. You will need to buy i>clicker and register it for this class at www.iclicker.com
Grade Policy
Exams 50% Lab 5%
Quizzes 5% Final 40%
You must pass both the lecture (3 midterm exams, final exam, homework) and laboratory parts of the coursein order to pass the course
Grade Policy (cont)
•If your grade on the Final Exam is higher than your lowest grade on one of the three exams during the semester, the grade on the Final will replace that one lowest exam grade in computing the course grade (it will only replace one grade in case of two exams having the same lowest grade). •The Final Exam grade cannot be used to replace an exam that has been missed without an University excused absence. The missed exam will count as a zero when computing your final grade.
Grade Policy (cont)
All Exams are
•Closed book
•No numbers! In general the problems will be formula solutions with variables
•Problems will be similar to those on homework and recitation
Homework
You’ll have weekly homework assignments
Every week you’ll have hw quiz with one problem from your assignment.
All quizzes will be given with i>clickers
Check my webpage for hw assignments
Example for Week 1 (Week Jan 19):
Week Jan 19 (due Jan 26): All Chapter 1 problems and exercises
“Due” means that I’ll give you a hw quiz on that day
Exam schedule
All mid-term exams will be from 7:00 to 9:30 pm
February 17 Exam I March 24 Exam II April 23 Exam III
Final May 8
My Advice to You• Be proactive!! Get into it and have fun• Always watch the chapter outline video and read
the book before you come to class• Be serious about an old rule of thumb: you have to
study 2-3 hours a week outside the class per each credit hour
• Don’t miss classes (lectures, recitations, labs)• Solve all problems and exercises after each Chapter
in the book• Don’t fall into the “I understand the concepts but I
can’t do the problems” trap. It means you haven’t done enough of the problems in the chapters.
• Every year we have lots of students who really think they understand but fail during the exams. Don’t let this happen to you!
I make help sessions before each midterm exam and the final. Week in review on Mondays
However, these sessions cannot substitute for regular class attendance. They are to give you a good guidance on how to prepare for the test and to succeed in problem solving.
Please check my webpage for help sessions schedule

Consider now a different type of a force…..
Consider a force like gravitation which varies as
but 1) billion-billion-billion-billion times stronger;
2) there are two kinds of “matter”: positive and negative; Like kinds repel and unlike kinds attract (unlike gravity where there is only attraction)

From long view of the history of mankind – seen from, say, ten thousand years from now – there can be little doubt that the most significant event of the 19th century will be judged as Maxwell’s discovery of the laws of electrodynamics. The American Civil War will pale into provincial insignificance in comparison with this important scientific event of the samedecade.
