CS 39R:  Symmetry & Topology
Lecture #1 -- Mon. 1/28, 2013.

Preparation:

Bring 2 different symmetrical objects to class.

Introductions -- Let's get to know one another!

Brief statements about yourself, the symmetrical objects you brought, and what you hope to get out of this course.

Warm-up -- Tackling symmetry:

Try to find at least two different symmetrical arrangements of  4 identical rectangular tables placed in a square room.
(Subsequently we will compare and classify results.) -- How many conceptually different arrangements are there?

Try to find a concise and general definition for "symmetry".

Is symmetry a "good thing"? -- What is it good for?

Make a name tag using your first name; try to make it symmetrical.
(Inspiration from Scott Kim).

First important concepts:

2D symmetry in art and architectural facades.

Symmetry in floor plans.

ASSIGNMENT:
Try to find many different symmetry groups in hub caps and in company logos; document the most exotic ones.

What is "antisymmetry" ?

Are there other symmetry operations ?

Some remarks on my teaching style:

--- Later course contents will be tailored somewhat to the interests of course participants.
==> Please state your interests on the  Background Questionnaire (later).

• Course Projects:
  Some individual study (with heavy use of the web): "The Role of Symmetry in: <Your Favorite Area>".


• Quizzes/Exams:
  Perhaps one or two short quizzes, to provide feedback whether the key concepts have sunk in.
  NO  Final Exam!

==> Please fill in the  Background Questionnaire now!

First Homework Assignment:

Try to find many different symmetry groups in hub caps and in company logos; document the most exotic ones (I-phone picture or sketch)
DUE: either electronically 9am, Monday, Feb. 4, -- or on paper at the beginning of the next lecture.
