Dancers Karl Schaffer, Saki, and Laurel Shastri perform a mathematical romp through dance, including combinatoric and rhythmic play with boxes, bottles and vaudevillian hats and a "Dance from the Book". Karl is co-founder with Erik Stern of the Dr. Schaffer and Mr. Stern Dance Ensemble, which has been revealing the surprising connections between mathematics and dance for years through highly physical, engaging choreography peppered with their unique brand of humor and entertaining audience interactions.
