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 new 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 and book your field trip at fieldtrips.momath.org or your tour at composite.momath.org today!

Conway’s Magical Pen
Wednesday, May 26, 6:30 pm ET (New York)
John Horton Conway, one of the most brilliant mathematicians of recent times, died in April 2020.  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.

Making Infinity Finite
Tuesday, May 27, 5:30 pm ET (New York)

Free Math Encounters: “Patterns in Permutations: the hidden and surprising structures that emerge from ordered lists” with Lara Pudwell
Wednesday, June 2, 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.

Senior Sessions: “Vote Counts: Tower of Power”
Monday, June 7, 2:00 pm ET (New York)

Explore the different ways power can be distributed in weighted voting systems.  These systems are those in which different groups have different amounts of votes, such as county delegations, government committees, and even the United States Electoral College.  Should the largest populations have the most power?  Should smaller groups have a voice?  Answering these questions is far more complex than simple majority rule, but modern mathematical analysis provides a useful lens through which to analyze unbalanced voting power.  (Please note: This is the third installment of the Vote Counts series; it is not necessary to have attended the other two.)  For senior citizens / mature adults.  Learn more and register at seniorsessions.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 as we gather in Paris, France for the fourth biennial MATRIX conference.  For more information and to sign up for notification when new dates are finalized, visit matrix.momath.org.


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 students 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.

Substitutions: Educator (part-time) and Substitute (per diem) positions available
If you enjoy the flexibility and pace of per-diem classroom education, consider applying to MoMath’s substitute educator program, Substitutions.  MoMath is looking for motivated, experienced substitute teachers who can engage a room full of students and share their love of enriching mathematics — training provided!  This program offers flexible scheduling to accommodate your needs, competitive pay, and the potential for regular engagement.  Learn more about educator positions and apply at jobs.momath.org.

Weekend programs for families
Take a tour with MoMath’s Derivatives program (derivatives.momath.org) or join one of MoMath’s specially-trained educators in Explorations, a hands-on classroom experience, to discover the wonder of mathematics (explorations.momath.org).  Don’t miss your chance to see math in a whole new light, only at MoMath.

Summations: MoMath’s homeschool program
Homeschool students can experience the excitement of a MoMath field trip!  With the Summations program, homeschoolers can spend the afternoon learning about the math behind MoMath’s engaging interactive exhibits or participating in an exploratory, hands-on classroom experience along with other homeschool families.  Learn more at summations.momath.org.
