The National Museum of Mathematics (MoMath) is celebrating “Pythagoras Day” with “Pythagorize Seattle 2017.” Starting Friday, August 11, individuals, families, and groups around Seattle will be able to download a MoMath app, designed by Lone Shark Games, to guide each participant through a monumental Seattle citywide math puzzle hunt.

The MoMath Pythagorize Seattle 2017 app will be available on the afternoon of Friday, August 11 in the app store and also on the MoMath website

Location data will be sent through a website. A smart phone or tablet is required to play along. Participants must physically visit locations in Seattle to check in. The MoMath Pythagorize Seattle Puzzle Hunt cannot be done remotely. It is appropriate for families, individuals, and groups.

“Pythagorize Seattle 2017” is expected to attract hundreds of fans of all ages and backgrounds around the city of Seattle over five days.

The celebratory culminating math event will happen on 8/15/17 – in alignment with Pythagoras Day. The event will take place at the Parkside Terrace of The Museum of History & Industry (MOHAI). (If it rains, the Lakefront Pavilion at MOHAI.) All attendees will “plant” pinwheels in a giant demonstration that will illustrate the Pythagorean Theorem that states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.* Each participant will receive a free Pythagorize Seattle 2017 T-Shirt, while supplies last.

MoMath is partnering with the Bezos Family Foundation, Oppenheimer Funds, Weyerhaueser, the Museum of History and Industry (MOHAI), the Pacific Science Center, and Math4Love to create “Pythagorize Seattle 2017.”

*The Pythagorean Theorem states that every right triangle has side lengths satisfying the formula a2 + b2 = c2. This year, the date 8/15/17 squared represents the sides of a right triangle: 64+225=289. The next Pythagoras Day will not be until 2024.
