**Questions**

Is the world lumpy or smooth?

Connected or disconnected?

Is there really a "Real World" out there?

__A Smooth World: Classical Continuum Space of Galileo and Newton__

Time and Space - Galilean Relativity

Motion in Space - particles: mass, force, energy, momentum

Motion in Space - waves: frequency, wavelength, types, the Doppler

Effect

Gravity and Electromagnetism

Einstein and the contradiction in Galilean relativity - Special

Relativity

General Relativity and Gravitation

__A Lumpy World: The case against Aristotle - matter is lumpy__

Molecules and Atoms

Energy and Light are also lumpy

Particles are waves and vice-versa????

Classical and Quantum Predictability

Can Events "Here" Influence Events "There"?

What glue holds stuff together - the field that binds

The world of elementary particles

__A Real World: Is it there?__

Can We Know It?

**Grades:** In
addition to some assigned homework and class work, there will be two hourly
exams and a final, all consisting of short (identify and signify) and long
(discuss and connect) essays. **No drops will be signed**
**after March 31, 2000.** (Students who fail to complete the required
course work, and who have not officially dropped, will receive a grade
I or E depending on the circumstance.)

Final grades for 3 credits based upon a maximum of 300 points:

A => 200 points; B => 100 points; C => 75 points.

Two hourly exams**:
100 points

Final exam
100 points

Collected homework*:
50 points

Interactive Question Papers* 40 points -in class (1 per session) and
collected.

[Since the answers to exams and homework will appear on the course
Web page immediately after they are collected, no late submissions will
be accepted.]

Oral class performance:
10 points
Honors students will be expected to turn in a term paper (worth 100 points), on a mutually agreed upon subject, in addition. Grades for honors students (4 credits) will be a weighed average of their paper grade and their 3 credit grade.

***Exams** will be based - to a large degree - on questions from
the Questions Papers and from the homework. Thus students who are conscientious
in preparing their home and class work should do well.

****Missed hourly exams** may be made-up, at the option of the instructor,
by a term paper.

**Homework Graded** as G(10), S(5), U(0). Assignments in March's
text.

__Due Monday 1/31__: Ch1.-2,4,10; Ch2.-1,2,4,9,10; Ch3.-4,5,7; Ch4.-2,3;

Ch5.-3,5,8; Ch6.-1; Ch7.-1,3,5a; Ch8.-2,3,4;

__Due Monday 2/21__: Ch10.-1,3; Ch11.-2,4,5,8; Ch12.-2,3;

__Due Monday 4/3__: Ch13.-1,2,3; Ch14.-1,2; Ch15.-2,4,5; Ch16.-1,3;

Ch17.-1,3;

__Due Monday 4/17:__ Ch19.-1,2,3,4.

**Syllabus** The
class will be run as a combination of lecture and

discussion, with emphasis on the latter! Productive discussion requires

that you have read (and thought about!) the appropriate text materials

(M for March, H for Herbert) before class. The discussions are intended

to help you understand the test materials and their implications. If
you

haven't read the materials before the class, you won't be able to

participate in the discussion - making for a very dull class! Also,
you

will not be able to ask questions appropriately about the reading you
do

not understand. Since the exams will cover both class and text material,

it would be wise to participate attentively in all class sessions as

well as to do all the reading carefully. Besides, discussing this

material should be fun and how can you discuss it if you have not read

the same stuff? "Interactive Question Papers" to stimulate discussion

will be distributed for each class.
