Lesson plan
Casey Mann
Casey Mann is an American mathematician, specializing in discrete and computational geometry, in particular tessellation and knot theory. He is Professor of Mathematics at University of Washington Bothell , and received the PhD at the University of Arkansas in 2001. He is known for his 2015 discovery, with Jennifer McLoud-Mann and undergraduate student David Von Derau, of the 15th and last class of convex pentagons to tile the plane. Mann is also known for his work on Heesch's problem, to which he contributed a polygon with Heesch number 5. This problem is closely related to the einstein problem, of whether there exists a shape that can tessellate space, but only in a non-periodic way.
