Mathematics 380
Bring a copy of this full syllabus (after it
is complete) to class on Monday, January 28.
Here's my single favourite
history of mathematics web site . Look there for more
information about the history of anything in mathematics.
Finally something worth adding: here are some places where you can
make tilings of your own. They will probably be useful in your create
symmetries project:
Using images, but limited
geometry.
Seems fascinating, worth
exploring.
Here's
something more.
Some static
ones that include more than the software creates (I think).
Here is the last assignment, due 3 May
Created examples:
Find (in the book or wherever you like) three symmetry patterns. At
least one must be spherical or hyperbolic. Try to choose diverse
symmetries (e.g. all kaleidoscopic patterns would not be the best).
For each:
0. Make 3 black & white copies of the pattern
1. Write the annotated signature and presentation for the pattern in terms
presented in Chapter 10. Indicate a fundamental region of the
original pattern.
2. Colour two of the copies in symmetric way using three
colours. For each of these colourings:
a. Write the signature of the coloured copy, and identify a fundamental
region.
b. For each colouring, include the colour signature and a justification
that it preserves the relations, along with some (probably simple) reason
that your two colourings are not isomorphic.
This assignment is significant, and also is singly worth 1/6 of your
course. Please be attentive to it.
(More will be added to this page as the semester progresses. Please
ask me if there is something you would like to see included.)
