GEORGE HART on “The Geometric Aesthetic” Hart is research professor in the department of computer science at Stony Brook University, New York, and a sculptor who makes impressionistic polyhedral sculptures — sometimes of plastic knives and forks — that are so complex they require a “barn-raising” to erect. He will speak about Coxeter’s influence on his art. “My sculpture would not exist if Coxeter did not exist,” says Hart. “Coxeter’s book Regular Polytopes opened my eyes to what geometry could be.” Hart is also the author of the web-based Encyclopedia of Polyhedra, which can be found at http://www.georgehart.com
DORIS SCHATTSCHNEIDER on “Coxeter and the Artists" Schattschneider, professor emerita of mathematics at Moravian College, in Bethlehem, PA, will speak about Coxeter’s collaborations with a number of artists, a subject on which she has investigated and written extensively. On this occasion she will include the British sculptor John Robinson, the painter and amateur geometer George Odom, based in Poughkeepsie, NY, and the Dutch artist M.C. Escher. Coxeter’s geometric figures of the hyperbolic plane directly inspired Escher’s Circle Limit III prints.
MARJORIE SENECHAL on "Coxeter, the verb" Coxeter’s name was already a proper noun — for example, Coxeter group and Coxeter diagram — but M.C. Escher transformed the geometer into a verb: working on his Circle Limit prints, Escher was known to say, “I’m Coxetering today!” “Escher spoke jokingly of "coxetering", but it’s no longer a joke,” says Marjorie Senechal. “We all coxeter now.” Senechal, the Louise Wolff Kahn Professor in Mathematics and History of Science and Technology at Smith College in Northampton, MA, and co-editor of The Mathematical Intelligencer, will explain what she means by this and propose a suitable entry — definition, usage, etymology — for the Oxford English Dictionary.
