Jill Bowdring and Katie Lovell -- Mathematics in M. C. Escher's Graphic Prints Excellent presentation and paper on Escher and the relation between his work and mathematical ideas. The choice of prints to discuss was perfect, and the use of the "manipulatives" of the tesselation patterns in the presentation was a very nice and imaginative touch! The paper is well-written, thorough, and shows quite a bit of independent thought about the implications of Escher's work. I think you will find this quotation from Escher's writing interesting and revealing: "[Mathematicians] have opened the gate to an extensive domain, but they have not entered the domain themselves. By their very nature they are more interested in the way in which the gate is opened than in the garden lying behind it." In other words, for mathematicians, the most interesting part of tesselations is understanding what the theoretical constraints are for making them (the way the gate is opened), not the amazing images you can create with them (the garden lying behind the gate). Starting to see what was in that garden was Escher's unique contribution! Specific Comments 1) The paragraph that starts at the bottom of page 1 and goes onto page 2 (the one about the "mathematical thinking, but not formal mathematics" aspect of Escher's work) is very good. However, it feels out of place where you placed it. I think that almost could have been a part of your conclusion at the end of the paper. 2) page 2: word choice: "would marvel any viewer" is not actually correct (technically, marvel as a verb is not transitive!). I think you mean something like "would impress any viewer" or "any viewer would find marvelous." 3) page 4: *Castrovalva* is not a "painting" :) I don't think Escher did very many paintings, in fact (maybe none at all?)
