MAT 103 ("Symmetries") : Course description, goals,
"Symmetry is a vast subject, significant in art and nature. Mathematics
lies at its root, and it would be hard to find a better one on which to
demonstrate the working of the mathematical intellect. I hope I have not
completely failed in giving you an indication of its many ramifications,
and in leading you up the ladder from intuitive concepts to abstract ideas."
This concluding statement in eminent Princeton mathematician Herman Weyl's
retiring address  remains as true today as it was many centuries ago:
symmetry is an abstract concept celebrated in concrete ways through the art
and culture of most known civilizations; it is this marriage between Life
and Mathematics that led an archeologist and a mathematician to join forces
and write a book  about it, used as a textbook in MAT 103 through
Students in MAT 103 learn to classify symmetric designs that either go
around Roman mosaics, Christian icons, African baskets, Maori boats, etc
("border patterns") or completely fill mosque domes, Peruvian textiles,
Chinese windows, Escher paintings , etc ("wallpaper patterns"); abstract
symmetric designs are also found in purely mathematical works such as 
and can be created by software packages like  or the instructors and
students themselves. The classification of these patterns is based on the
listing of the isometries (i.e., geometric transformations preserving
distances therefore figures as well) that leave the pattern unchanged,
and the investigation of the interactions among them.
Listing the isometries of a pattern simply amounts to the successful
handling of a form of graphical data and what we call "critical seeing".
To achieve that, students first go through a hands-on study of the effect
of specific isometries (such as rotation and glide reflection) on specific
figures, and they also learn to reconstruct the isometry from its effect.
Investigating the interactions among such isometries requires a deeper
geometrical insight (but still not extending much further than ordinary
high school geometry) and leads naturally to the abstract, yet fundamental
in nature, concept of a group. Students construct at least one group table
arising from compositions of isometries, best understood in the context of
their effect on color and appropriately colored tilings. Such tile or "map"
colorings and their interplay with symmetry  can almost at the same time
entertain the child and challenge the mathematician.
MAT 103 is a rather unconventional course, and this is best underlined by
the absence of genuine textbooks in the area. Brilliantly written by an
architect,  is probably the only book potentially suitable for the
General Education student, but it fails to take color into consideration.
We largely resolve this problem using handouts and encouraging team work
during labs completed in class. We hope to facilitate the students' learning
by the creation of a web page or, possibly, the publication of a locally
produced textbook. After six years of successful implementation, MAT 103
is turning more and more mathematical. It is more technical, for example,
than a similar course taught at Dartmouth and presented there during the
Mathematics and Art Together in the Classroom workshop (June 26-28, 1997).
Still, the students learn quite a bit about art and native cultures.
MAT 103's spirit is probably best captured in the words of a Gulf War
veteran and Fort Drum soldier who graduated from SUNY Oswego in May 1997:
