*Math Encounters*: "Tales of Impossibility: The Problems of Antiquity" with David Richeson

(4:00 pm)

“Nothing is impossible!" While it is comforting to believe this greeting card sentiment — it's the American dream, after all — there *are* impossible things. Ancient Greek geometers and future generations of mathematicians tried and failed to square circles, trisect angles, double cubes, and construct regular polygons using only a compass and straightedge. Join David Richeson, Professor of Mathematics at Dickinson College and Editor of *Math Horizons*, to try your hand at some of these unusual geometric construction techniques. But get ready to fail — after two thousand years, all four of these “problems of antiquity” have been proved to be mathematically impossible!
