Dear MoMath friends,

Spring is in the air and MoMath is taking it to the streets!  First, we kick off May with Graph the Grid — join us in creating Manhattan’s largest-ever human parabola.  Then, don’t miss two days of fun in the sun as Madison Square Math takes over 26th Street between 5th and Madison, right outside the Museum, as part of the NYC Open Culture initiative.  Not in the tristate area?  Bring math to your own neighborhood with Global Perspective, featuring stunning mathematical sculptures by Anton Bakker — plus join Anton at his two upcoming online events, focusing first on spirals and then on tessellations.  Looking for yet more mathematical enjoyment?  You can play with permutations, produce a parabola, and ponder some puzzles.  From fractions to fractals, isosceles to infinity, and Pascal to poetry — MoMath is your one-stop shop for ongoing mathematical engagement!

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.

Conway’s Magical Pen
Wednesday, May 26 at 6:30 pm ET (New York)
John Horton Conway, one of the most brilliant mathematicians of recent times, died in April 2020.  While contributing to many diverse fields of mathematics, he delighted in amusing people.  One of his playful contributions to mathematics was in the subject of tiling (tessellations), and is called the “Conway Criterion.”  Any shape that conforms to his criterion will fill the plane with its copies, fitting together like jigsaw pieces, just by rotating the tile by 180 degrees repeatedly about certain points on its edges.  To honor his memory, an app called Conway’s Magical Pen has now been developed.  Join us for an evening of exploration led by artist and technologist Anton Bakker, who will be joined by mathematician Doris Schattschneider and app developers Jonathan Bailey and Herman Tulleken.  Learn how you can use the app to make, freehand, “Conway tiles” that are guaranteed to tile the plane.  Your tiles can be simple or complex, straight or swirly, abstract or Escher-like — what you create is limited only by your imagination!  Learn more and register at magicpen.momath.org.

Discover how surprising patterns can emerge from simple rules as we “add” colors to determine new results — and create mathematical art in the process!  How are 2, 3, 5, and 7 different from 4, 8, and 9?  Why is 6 so much more chaotic than the other numbers?  Joshua Zucker is our fearless leader as we explore mathematical patterns at this clever, creative, and compelling evening event.  Learn more and register at fractal.momath.org.

Math Encounters: “The Structure of Space: Measuring the Shape of the Universe” with David Spergel (free registration)
Wednesday, July 7 at 4:00 pm and 7:00 pm ET (New York)

Is the universe infinite or finite?  Will it expand forever or collapse in a hot Big Crunch?  And what is its shape?  Join David Spergel, Director of the Center for Computational Astrophysics, Flatiron Institute, as he introduces geometry and topology, the mathematical concepts used to answer these questions.  Learn how observations of the microwave background (the leftover heat from the Big Bang) have revealed the universe’s shape and can help predict its destiny.  Special introduction by Janna Levin, Claire Tow Professor of Physics and Astronomy at Barnard College of Columbia University.  Learn more and register for free at mathencounters.org.

MOVES Meet-Up
Sunday, August 8 at 3:00 pm
ET (New York)
The MOVES conference has MOVED — from August 2021 to January 2022.  But for those who were holding the August date, an online event is still planned for the afternoon of August 8.  The plenary speakers from the conference are designing puzzles and activities for a collaborative and social Zoom get-together, with a separate “room” for the kids.  Learn more and register at augustmoves.momath.org.

MATRIX x IMAGINARY 2021
Due to the current health situation, the MATRIX x IMAGINARY conference has been postponed.

MoMath is pleased to announce that it is joining forces with Institut Henri Poincaré and the IMAGINARY team to bring you MATRIX x IMAGINARY 2021.  If you work with a math museum or want to create one; if you design, create, or operate math exhibits; or if you are involved or want to be involved in math outreach or creative math programming, then this is the conference for you!  Join us for four days of sharing, networking, and learning at the fourth biennial MATRIX conference.  For more information and to sign up for notification when new dates are finalized, visit matrix.momath.org.


ONGOING OFFERINGS

Perspectives: The MoMath Summer College Volunteer Program
Each summer, MoMath offers Perspectives, a volunteer program for college undergraduates.  Students who complete Perspectives gain a strong level of knowledge and experience in what it takes to operate a successful business, as well as exposure to a variety of interesting programs, lectures, and people.  The expected commitment is five days per week for eight to twelve weeks, and it typically includes assignments on the floor of the Museum, in the retail shop, and in MoMath’s administrative office.  Perspectives is an unpaid volunteer program.  MoMath is currently accepting applications for summer 2021 and will be admitting candidates on a rolling basis.  Learn more and apply at perspectives.momath.org.

Integrators: The MoMath High School Volunteer Program
MoMath accepts a limited number of high school students for ongoing volunteer roles during summer vacation and/or the academic year.  The Integrators program offers a unique chance to improve interpersonal and communication skills, explore mathematical concepts, and learn valuable job skills.  MoMath Integrators interact with visitors (on the Museum floor or online) and train with professional educators, interpreters, and managers.  Students who participate during summer vacation commit five days per week.  During the school year, this opportunity requires a commitment of approximately one day per week, typically a Saturday or Sunday, from September through June.  Apply now for summer 2021 (online and/or in person) or the 2021-2022 school year.  Applications will be accepted on a rolling basis.  Learn more and apply at volunteers.momath.org.

School and group visits
MoMath has almost two dozen great programs, from constructing polygons to creating Möbius strips, 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.
