Pythagorize Seattle

— 8/15/17 —

Events will begin on Friday, August 11

Join the National Museum of Mathematics as we return to Seattle to celebrate another Pythagoras Day — the last (primitive) Pythagorean triple until 2024! Made possible by the Bezos Family Foundation, OppenheimerFunds, and Weyerhaeuser, this year’s event will unfold in multiple stages, featuring a city-wide puzzle hunt designed by Lone Shark Games to engage individuals, groups, and families alike. Help us show the world that New York isn’t the only place where math can be the bedrock of an amazing mathematical celebration. What better place than Seattle to demonstrate the awesome power and sheer coolness of mathematics?

What is Pythagorize Seattle?
On Pythagoras Day 2015 (08/17/15), MoMath brought an all-new MathHappening to the city of Seattle. This collaboration celebrated Seattle’s historic Triangle Pub, measuring 8 meters x 15 meters x 17 meters — a Pythagorean triple that just happened to correspond with the date. Hundreds of Seattle-based math lovers flocked to Lake Union Park on 8/17/15 to become part of a large-scale human illustration of the Pythagorean theorem. This first occurrence of Pythagorize Seattle was the largest mathematics demonstration Seattle had ever seen. You can view photos from Pythagorize Seattle 2015 at

Beginning on 8/11/17 and culminating in an event on Pythagoras Day, 8/15/17, MoMath returns to host another wildly popular public celebration of math, the Pythagorean theorem, and Seattle.
