Historic ‘Tile’ Discovery Gives Math World a Big Jolt
Casey Mann, Jennifer McLoud-Mann,
Mathematics Dept., UW Bothell
The problem of classifying all convex pentagons that admit tilings of
the plane has a rich history, and because the problem is still
unsolved, it continues to generate interest in mathematics by budding
mathematicians. The history of this problem starts way back in 1900
with #18 of Hilbert’s famous 23 problems (and even further). Many
mathematicians have made contributions toward a classification,
including amateur mathematician Marjorie Rice, who single-handedly
discovered 4 new types in the 1970s. After describing the history and a
few key mathematical concepts, Casey and Jennifer will describe the
method by which their team discovered the 15th type of convex pentagon
that tiles the plane. The mathematics involved is pretty accessible.
Come and find out how history was made right here at UW Bothell!
