The Hat: an aperiodic monotile
Thursday 20 July, 2023
6pm – 7.15pm Andrew Wiles Building, Mathematical Institute, Oxford

This talk and panel discussion will celebrate the discovery of a single shape that completely covers an infinitely large flat surface without repeating.

The famous Penrose tiling is made of two elementary shapes, or tiles, and mathematicians have long wondered about the existence of a single tile that could tile the plane aperiodically. Earlier this year such a shape was discovered: the Hat!

For this public talk, organised in partnership with the Clay Mathematics Institute, Chaim Goodman-Strauss (National Museum of Mathematics/University of Arkansas), one of the authors of this new work, will give an overview of the Hat.

This will be followed by a panel discussion featuring Craig Kaplan (University of Waterloo), Marjorie Senechal (Smith College) and Roger Penrose (University of Oxford) as well as Chaim Goodman-Strauss. The discussion will be chaired by Henna Koivusalo (University of Bristol).
