Dear MoMath friends,

What do colored dots, ancient tablets, and Indian music all have in common?  It’s mathematics, of course.  From studying patterns using color to exploring our shared human history to enjoying the emotional impact of rhythms, math has a way of connecting us all.  And now, connections begin anew as the Museum reopens to the public, welcoming visitors from near and far to experience MoMath’s interactive, engaging array of unique exhibits, including the groundbreaking new exhibit, Alternative Perspectives.  Not in New York?  Don’t worry; the Museum will continue to serve patrons from around the world with online programming for all.  Join us in person or remotely — everyone will find a warm welcome as they step into the wonderful world of mathematics.

Please enjoy the following programs and activities, all available online unless noted otherwise.  Additionally, many of MoMath’s programs are being offered for free or at a reduced rate for those in need and for those with MoMath memberships — please visit individual event pages for more information.
