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!  A free t-shirt featuring your design will be delivered to ten lucky participants. Learn more and register at magicpen.momath.org.

Making Infinity Finite
Thursday, May 27 at 5:30 pm ET (New York)
Many infinite processes are hard to understand — and the computations involved in infinity might take an infinitely long time.  Even shortcuts usually require calculus or other fancy tools — or do they?  Algebra to the rescue!  With a little help from Joshua Zucker and his trusty algebraic toolbox, we’ll turn an infinite process into a one- or two-step equation, then apply our new tool to probability, decimals, and even to infinitely nested computations.  Learn more and register at infinite.momath.org.

Senior Sessions: “Prime Time”
Friday, May 28 at 2:00 pm ET (New York)
Come explore modular arithmetic and prime numbers by learning about Cayley graphs, which resemble circular connect-the-dots patterns but encode important mathematical information.  Turn multiplication problems into simple shapes and discover the surprising patterns that emerge.  For senior citizens / mature adults.  Learn more and register at seniorsessions.momath.org.

Folding Fridays
Friday, May 28 at 4:30 pm ET (New York)

Math Encounters: “Patterns in Permutations: the hidden and surprising structures that emerge from ordered lists” with Lara Pudwell (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.  Special introduction by Dr. Jennifer Quinn, Professor of Mathematics, University of Washington Tacoma, and President, Mathematical Association of America.  Learn more and register at mathencounters.org.

Ask a Mathematician — Anything!
Thursday, June 3 at 4:00 pm ET (New York)
Ever wanted to ask a mathematician something, maybe about a curious new idea you have, or a concept you’d like to understand better?  Don’t know whom to ask?  Here’s your chance!  MoMath’s 2020-2021 Distinguished Visiting Professor for the Public Dissemination of Mathematics, Alex Kontorovich, will host this one-hour, online session.  Learn more and register at askmath.momath.org.

Diversity in Computing: Challenges and Possibilities
Wednesday, June 9 at 6:30 pm ET (New York)
Data science, machine learning, and artificial intelligence are among the fastest-growing technologies of the 21st century.  The rapid adoption of AI and data-driven decision making will have a substantial impact on job availability, privacy and security, education at all levels, business operations, accessibility of information, scientific activity, and how we interact with each other and with the world around us.  The potential challenges of this transformation include data bias, misinformation and disinformation, privacy and security concerns, and autonomy and accountability.  In order to ensure that all members of society benefit equally from these technology advances, it is essential for the industry to recognize, understand, and mitigate against potential negative consequences.  One of the best ways to accomplish these goals is to increase the diversity of the engineers who create these systems.  Join computer scientist Dr. Marie desJardins for an engaging discussion about the current state of AI, machine learning, and data science; the future of AI technology; the importance of diversity for creating robust, effective engineering solutions; and how we can thoughtfully ensure that these technologies will positively affect our lives and the lives of generations to come.  Learn more and register at diverseai.momath.org.

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: now booking for the 2021-2022 school year, in person and online!
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 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.
