The National Museum of Mathematics (MoMath) has revealed its June and July highlights of its summer season. MoMath recently relocated to its new home at 635 Sixth Avenue in Manhattan’s Chelsea neighborhood.
MoMath features more than 70 exhibits, including new displays and popular favorites designed to showcase the beauty and fun of mathematics for people of all ages and backgrounds. The 46,000-square-foot facility features a dedicated space for early learners, a state-of-the-art presentation space, six classrooms, and space for seated dinners, cocktail parties, conferences, school groups, and community programs.
“This summer marks an especially exciting moment for the National Museum of Mathematics as we continue building momentum in our new home and expanding the ways we share the wonder and beauty of mathematics,” said Cindy Lawrence, Executive Director and CEO of the museum. “Alongside our popular public programs and uniquely engaging exhibitions, we are proud to be hosting an international conference that will convene leading voices in math outreach from around the world, as well as an immersive learning seminar for educators and a professional development program designed to foster outreach efforts among women in math. Together, these initiatives reflect MoMath’s commitment to fostering curiosity, community, and opportunity for people of all ages and backgrounds.”
June and July happenings feature a wide range of activities including a hands-on session with Dr. Tiago Hirth exploring classic stage illusions through the lens of topology, the mathematics of shape and connection. The MoMath Annual Puzzle-hunt Series (MAPS) will be presented by puzzle-creator extraordinaire Dr. Rik Sengupta and offers participants the challenge of working in teams to solve a series of puzzles in outdoor locations near the Museum. Dr. Lew Ludwig explores the concept of infinity through hands-on activities and guided inquiry.
That Math Show opens June 21, presented in association with The Science Theater Company at the Off-Broadway Theater 555. That Math Show is created by and features MoMath’s Visiting Professor for Pubic Outreach, Dr. Arthur Benjamin, who shares the beauty and magic of mathematics. Dr. Benjamin will also do a 67-minute presentation at MoMath on The Magic of 6 and 7 on, aptly, June 7.
At Family Fridays on July 10, “Bubbleologist” Steve Langley presents a memorable evening of remarkable bubble artistry exploring the mathematics of shape, symmetry, surface, and the floating form.
Dr. Annalisa Crannell participates in MoMath’s signature series Math Encounters on July 8, exploring how perspective geometry helps artists create convincing depictions of the three-dimensional world and can also produce astonishing illusions.
MoMath will present its 10th annual NYC Math Festival on July 11, featuring a wide variety of math-related exhibits, puzzles, games, encounters, and presentations celebrating the all-encompassing field of math. The festival is free and open to the public.
Hosted by MoMath, the MATRIX x IMAGINARY 2026 conference gathers exhibit designers, museum leaders, creative educators, math writers, and math outreach innovators from around the globe to share discoveries, innovations, and breakthroughs in many math-related fields. Attendees will get to meet YouTube superstar Grant Sanderson (3Blue1Brown), participate in a discussion with two Fields Medalists, and meet prominent math and science authors.
Throughout 2026-The Year of Math-MoMath is highlighting mathematics as a living, creative practice through a series of monthly experiences designed to invite participation and conversation. To subscribe, visit momath.org/yearofmath.

What do ropes, rings, and rubber bands have to do with mathematics? In this hands-on session, Dr. Tiago Hirth from the University of Lisbon explores classic stage illusions through the lens of topology, the mathematics of shape and connection. Participants experiment with knots, links, and the surprising structure of the Borromean rings, discovering how simple objects can reveal deep mathematical ideas.
Family Fridays are designed to bring family members of all ages together to enjoy a diverse array of engaging mathematical activities, promoting interest and enthusiasm among kids and adults alike. Please note that all children under 16 must be registered and accompanied by a registered adult chaperone.
MAPS – MoMath Annual Puzzle-hunt Series with Rik Sengupta

Free with Museum Admission
Registration includes complimentary admission to MoMath for the day.
Back by popular demand, join puzzle-creator extraordinaire Rik Sengupta, research scientist at IBM Research, Cambridge, MA, for this exciting new series at MoMath. Teams of four to six solvers explore nearby locations outside the Museum while solving a series of fun puzzles. Teams may include up to six people, but each participant must be registered individually.

Sunday, June 7 | 2:00 pm to 3:00 pm
Free with Museum admission
https://momath.org/6-7/
Mathematician Dr. Arthur Benjamin celebrates the 6/7 phenomenon with a special 67-minute presentation on The Magic of 6 and 7. Visitors can continue the fun playing with the game Connect 4’s classic 6-by-7 grid. All registered children under 16 must be accompanied by a registered (paying) adult.
Math Encounters
“How Big is Infinity? How Big is Your Mind?” with Dr. Lew Ludwig
Wednesday, June 10 | 4:00 pm and 7:00 pm
Free with Museum Admission
https://momath.org/math-encounters/
Infinity is one of the most mysterious ideas in human thought; it’s not a number you can calculate or a destination you can reach. Join Lew Ludwig, Professor of Mathematics at Denison University, Granville, OH, for a journey into this elusive concept along with a surprising question: are there actually different sizes of infinity? What could “size” mean when nothing ever ends, and how can we compare two quantities that are both infinite? Through hands-on activities and guided inquiry, participants explore these seemingly impossible ideas and reveal what human reasoning can uncover about the infinite. No advanced mathematics is required-just curiosity and an open mind.
Math Encounters is MoMath’s popular free public presentation series celebrating the spectacular world of mathematics.
