Dear MoMath friends,

After a long winter, it’s time to hit the streets with MoMath.  Celebrate springtime with some A-Maze-ing Math on the Flatiron Public Plaza, in honor of Math and Statistics Awareness Month.  Then, help MoMath create the largest human parabola Manhattan has ever seen as we Graph the Grid — all in a safe, socially-distanced way.  Or kick back at home and celebrate the creative construction of songs, poetry, and art; learn how to play bridge or tile the plane; and enjoy an incredible, true-story film about how one man’s obsession with patterns in nature resulted in mathematical and scientific discovery.  Whether you’re indoors or out, alone or in a group, a student, a senior, or anything in between, MoMath breathes life into math and brings math to life!

Due to the current health situation, the Museum is temporarily closed.  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.

Online tours and field trips to Composite, the gallery at MoMath — take a tour with artist Anton Bakker and explore the amazing Alternative Perspective exhibition
MoMath is thrilled to present a groundbreaking art show in Composite, the gallery at MoMath — virtually!  In Alternative Perspective, artist Anton Bakker takes us on a journey into a world of mathematical beauty with an added twist: a change in perspective seems to change the very reality of the object before you.  Anton’s sculptures — executed in steel, bronze, or as digital interactives — fix points in space that, as the eye connects them, reveal harmonious alignments as three-dimensional paths.  Lines, curves, knots, spirals, Möbius strips, optical illusions, and fractals — all are explored in this highly engaging virtual show.  Bakker’s work is complemented by two special pieces: an unusual and surprising work by engineers-turned-artists Walt van Ballegooijen and Hans Kuiper and a creative mathematical sculpture by former Bell Labs scientist Alan White.  Learn more about MoMath’s newest temporary exhibition at composite.momath.org.  Book your field trip at fieldtrips.momath.org or your tour at composite.momath.org today!

Math Encounters: “Matchings and Couplings: Domino tilings of a chessboard and other tales” (free registration)
Wednesday, April 7 at 4:00 pm and 7:00 pm ET (New York)
Covering a chessboard with dominoes might sound like a curious blend of old pastimes, but in reality these tilings reveal rich and beautiful mathematical structures.  Interesting patterns can be found in the geometric arrangements of dominoes, as well as in the numerical counts of tilings of chessboards and related regions.  Alternatively, viewing each domino on the chessboard as pairing a black square with one of its neighboring red squares, tilings can be interpreted as assigning 32 pairs.  Viewing these “matchings” in a variety of contexts, Georgia Tech ADVANCE Professor of Computing Dana Randall shares a surprising array of applications, from the physics underlying collections of diatomic molecules to dating algorithms for forming couples in a community.  Special introduction by Peter Winkler, William Morrill Professor of Mathematics and Computer Science at Dartmouth College.  Learn more and register at mathencounters.org.

Bending Lines (free to members)
Tuesday, April 13 at 6:30 pm ET (New York)
The documentary film Bending Lines is a story of obsession, of vision, and of the enduring conversation between art and science.  It uncovers the aged Robert Wiggs, an amateur mathematician, obscured by time and his profession, whose artistic work communicates the universal quest to discover the essence of the natural world.  Never formally trained in mathematics, Wiggs looks back on a lifelong obsession with patterns in nature that helped him create a sculptural geometric system that rivaled the work of academic mathematicians, and eventually led him to scientific discovery.  The film had its world premiere at the Full Frame Documentary Film Festival in 2018 and has since gone on to screen throughout the world at conferences and festivals with a high focus on art, intellectual curiosity, nature, and mathematics.  An exclusive screening of the film (82 minutes) will be followed by a panel discussion featuring Allison and Peter DeHart, the film’s directors; Calvin Wiggs, geologist and son of Robert Wiggs; and Carlo Séquin, UC Berkeley physicist, computer scientist, and mathematical artist.  Learn more and register at bending.momath.org.

Math Encounters: “Patterns in Permutations: the hidden and surprising structures that emerge from ordered lists” (free registration)
Wednesday, June 2 at 4:00 pm and 7:00 pm ET (New York)
A “permutation” is a list where order matters.  Despite this humble definition, permutations offer a wealth of beautiful mathematics that can be applied across scientific disciplines.  Starting simply, with small ordered lists, mathematician Lara Pudwell demonstrates how smaller permutations can be embedded into larger permutations.  The results are both unexpected and delightful — not only do some familiar patterns suddenly appear, but this embedding gives rise to a host of interesting counting problems with connections not just to mathematics, but to computer science, chemistry, and more.  Learn more and register at mathencounters.org.

School and group visits
MoMath has more than one dozen great programs, from graph coloring to Möbius bands, for school groups visiting the Museum, in person and online.  Bring your students to MoMath — virtually! — for a peek into the exciting world of mathematics, and see why students and teachers of all ages love the Museum.  Register at fieldtrips.momath.org.

Free trips for Title I schools
Thanks to contributions from individuals and organizations including Adams & Company, Con Edison, The Scripps Family Fund for Education and the Arts, Two Sigma, New York City Council Members Mark Levine (7th District) and Carlina Rivera (2nd District), plus several generous MoMath friends, support for Title I schools is now available.  This program is supported, in part, by public funds from the New York City Department of Cultural Affairs in partnership with the City Council.  To apply for a free trip (online) during the 2020-2021 school year, visit titleone.momath.org.  Interested in sponsoring a field trip?  Email donation@momath.org.
