Student Colloquium on Mathematical Crystallography
by Justin Roberts, Nov. 13
In the words of the great Lobachevsky, "Plagiarise, plagiarise,
plagiarise!". All these images and webpages I'm using in my talk
belong to other people. You should look at these beautiful pages for a
lot more information! Also, the books by Montesinos (Classical
tessellations and 3-manifolds), Thurston (The geometry and topology of
3-manifolds) and Grunbaum and Shephard (Tilings and Patterns) are very
helpful.
