Mathday, 2020


Mathday will be held on Monday, March 23, 2020. The plenary speaker will be Allison Henrich, Professor of Mathematics, Seattle University. She will speak on It's all fun and games until someone becomes a mathematician. PLAY is essential for human flourishing. Whether you are a poet or a scientist, a grandparent or a toddler, play can powerfully enrich your life. For mathematicians, play is essential for building intuition, and for math students, play can inspire a desire to get involved in research. The world of knots gives us examples that help us understand these connections. Playing games on knot diagrams can help us build intuition about knotty structures, while learning about the theory of knots can reveal the “magic” behind rope tricks and excite us to learn more.

There will be talks, seminars, labs, and more activities from 10 am until noon and from 1:20 pm until 2:00 pm. Registration forms, which will include the schdedule of fees, are now available.
