Math Hour | Math Hour Olympiad | Past Events | UW Math Circle |
Each spring, Seattle-area middle- and junior high-school students are invited to participate in the Monthly Math Hour at the University of Washington. The 2023 Math Hour talks will take place in person on the UW campus, in the Architecture building, room ARC 147.
Well-behaved parents and teachers are also welcome to attend with the permission of their children. Siblings are free to join in, too.
There will be time for questions and further discussion after the talks.
The talks are free, and registration is not required — just show up! However, registration is required for the Math Hour Olympiad, due to limited capacity: more information will be released through our mailing list.
If you have any further questions or comments, please contact:

Counting in Catalan: Handshakes, Trees, and Paths
Kyle Ormsby, Reed College and University of Washington
Abstract: In this talk, we'll uncover how trees, parentheses, handshakes, triangulations, and mountain ranges are all counted by the sequence of Catalan numbers: 1, 1, 2, 5, 14, 42, …. Along the way, we'll learn the fundamentals of combinatorics — the mathematics of counting — including the additive and multiplicative counting principles, factorials, binomial coefficients, recurrence, and the one concept that rules them all: bijection. We'll conclude by contemplating an open question that has stumped mathematicians for over 100 years — maybe you can solve it!
