MoMath announces with sadness the passing of Jim Simons, a visionary whose leadership and generosity were instrumental in the creation of the National Museum of Mathematics.

MoMath is proud to honor Jim’s legacy by sharing the wonder, beauty, and critical importance of mathematics with people of all ages and backgrounds — from New York, around the nation, and worldwide. His contributions were truly extraordinary. Thank you, Jim.

Welcome to the National Museum of Mathematics!

MoMath, the National Museum of Mathematics, is an award-winning museum that highlights the role of mathematics in illuminating the patterns and structures all around us.  Its dynamic exhibits, galleries, and programs are designed to stimulate inquiry, spark curiosity, and reveal the wonders of mathematics.  The Museum’s innovative exhibits will engage visitors of every age, from 1 to 100!

Visitors are strongly encouraged (but not required) to wear masks upon entry and while visiting the Museum.

We’ve moved!  MoMath on Fifth, a popup experience, is located at 225 Fifth Avenue in Manhattan and is open from 10:00 am to 5:00 pm, seven days a week, 364 days a year.

Groundbreaking Discoveries in Mathematics

Learn about the amazing discovery of the “einstein tile” known as the Hat and its close relative, the Spectre, a “chiral” aperiodic monotile. Both are the first-ever shapes that can tile the plane endlessly but only without ever quite repeating the pattern, discovered by math enthusiasts and researchers David Smith, Joseph Samuel Myers, Craig Kaplan, and MoMath’s very own Chaim Goodman-Strauss.  Read about these shapes and hear the stories behind each discovery!  Visit and for articles, videos, and even a creative art competition inspired by these discoveries!
