## Scientific General Events

The best and worst of Henri Poincaré’s mistake.

The Hidden Beauty of Mathematics

The Pacific Northwest Dynamics Day is an annual one-day meeting to bring together researchers in dynamical systems across the Pacific Northwest for a one-day meeting every Spring. The event includes 5 talks, 4 by local researchers and 1 by an outside expert, and we particularly encourage early-career researchers to attend and participate. We have social events at lunch and dinner (as well as the usual coffee breaks).
