ACA has planned a free public lecture in association with its national meeting this month.
“M. C. Escher and the Crystallographers”
Saturday, May 24 * Noon–1:00 pm
Given by: Doris Schattschneider, PhD
Abstract: Just as crystallographers classify the objects they study by the symmetries of 3D molecular structures, Escher’s art is governed by the possible symmetries of repeating patterns in the plane. Wanting to discover the underlying rules of geometry that governed tessellations, Escher undertook his own personal investigation and developed his “layman’s theory” that later was recognized by a crystallographer and led to collaboration with her on a book that used his illustrations to explain color symmetry. Learn about his work with crystallographers and how he made those intricate tessellations.
Doris Schattschneider is professor emerita of mathematics at Moravian College, Bethlehem, PA. Her primary interest is geometry on the topics of symmetry, geometry and art, and visualization. She was geometer and senior associate on the NSF-funded Visual Geometry Project. In 1993 she received the national MAA Award for Distinguished Teaching of College or University Mathematics. She is currently an associate editor of the Journal of Mathematics and the Arts. She has a PhD in mathematics from Yale University.
