Have a Great Weekend of Browsing!

Occasionally, serendipity (and luck) leads me to the doorsteps of obscure web sites. This week's web site is an example. On e-bay, I was poised to make a bid on a large set of past issues of the journal Structural Topology. Having not heard of the journal previously, my motivation was the listing's statement that the set included a full issue devoted to the work of M.C. Escher. While waiting to make the bid, I browsed our University's library to see if they had past copies of the journal...and to my surprise....

It turns out that all copies of the journal Structural Topology are on-line in PDF-format...and they can be down-loaded for FREE! And what a find this "electronic" journal has turned out to be. If you teach and enjoy geometry, you will find it an interesting resource.

Basically, the journal was an out-reach effort of the Structural Topology Research Group at the University of Montreal. When a grant from the Quebec Government elapsed, the group ceased publication of the journal in 1997. To provide some background for the journal's content, the Structural Topology group was an interdisciplinary team of architects, engineers and mathematicians whose interest was "to apply classical and contemporary mathematical tools to the solution of morphological and structural problems in architecture and structural engineering." Beginning with a research focus on polyhedra, space-filling, and structual rigidity, the group (and the journal) branched into the areas of art, teaching geometry, properties of space, etc.

As motivation for your trip to this site, consider this sample of articles:

  • Escher's Lizards
  • The Algebraic Escher
  • Napoleon, Escher and Tesselations
  • Escher: A Mathematician In Spite of Himself
  • Twelve Exercises in Spatial Perception
  • Spatial Representation and the Teaching of Geometry
  • Rigid Circle and Sphere Packings
  • Architecture and Geometry
  • On the Cohomology of Impossible Figures
  • Four-Dimensional Regular Hexagon
This is only a sampling...more treasures await if you browse every issue on your own. And if you read French, you can get some related practice in that area as well.
