George Hart is a sculptor and applied mathematician who demonstrates how mathematics is cool and creative in ways you might not have expected. Whether he is slicing a bagel into two linked halves or leading hundreds of participants in an intricate geometric sculpture barn raising, he always finds original ways to share the beauty of mathematical thinking. An interdepartmental research professor at Stony Brook University, he holds a B.S. in Math and a Ph.D. in EECS from MIT. His research explores innovative ways to use computer technology in the design and fabrication of his artwork, which is exhibited widely around the world. Hart co-founded the Museum of Mathematics in NY City and developed its initial set of hands-on exhibits. See georgehart.com for examples of his work.
