MoMath October – November 2024 Upcoming Events

Dear MoMath friends,

Vote for MoMath!  Join Visiting Professor David Reimann for a series of programs throughout the month of October — book discussions, movie nights, and more — all touching on the math of voting.  Or put on a more artistic hat and try your hand at topological crochet, weekly origami jams, or a brand new minicourse where you can get up close and personal with symmetry and perspective in art, while also getting to know — and learn from — Professor Reimann.  Want to challenge your mind?  Join the monthly Math Gym or ramp up to some even more challenging math problems from the American Mathematics Competition (for grade) 12.  Students can fall in love with math every Tuesday, join a one-day mini-camp, take a new peek at My Dear Aunt Sally, or become detectives using graph theory, while adults can learn about Lean (a computer-based proof assistant) or spend a fun evening at play during Equilibrium, MoMath’s monthly gaming meetup.  Whatever your age, whatever your interest, join MoMath to experience the fun and engaging side of math.

Visit MoMath on Fifth, MoMath’s pop-up space, located at 225 Fifth Avenue in New York City: open from 10:00 am to 5:00 pm, seven days a week, 364 days a year.  The Museum will be closed on Thanksgiving Day, Thursday, November 28.  Purchase admission tickets, become a member, and check out upcoming events, in person and online!

Free! Math Encounters: “You Want Proof?  I’ll Give You Proof!  Mathematical Arguments from Euclid to Lean” featuring Jeremy Avigad
Wednesday, November 6, at 4:00 pm and 7:00 pm ET (in person)

Although proof has been central to mathematics from ancient times, our understanding of what a proof is has evolved in interesting ways.  In the 17th century, Isaac Newton proved things about quantities that are infinitely small while in the 19th century, Georg Cantor proved things about quantities that are infinitely large.  Some proofs rely on calculations that are too long to carry out by hand, whereas there are collaborative proofs that are too large to be understood by any one person.  Now, we can even write proofs in such a way that a computer can understand them and determine whether or not they are correct — and, by the way, so can AI!  Join Jeremy Avigad, Professor of Philosophy and Professor of Mathematical Sciences at Carnegie Mellon University, in an exploration of recent developments that challenge our understanding of mathematical proof.  You’ll even get to experiment yourself with contemporary proof-checking technology.  Math Encounters is MoMath’s popular free public presentation series celebrating the spectacular world of mathematics, produced with support from Simons Foundation International.  Register at momath.org/math-encounters.

Free! Family Fridays: “Möbius Moves” with Richard Schwartz
Friday, November 8, from 6:30 pm to 8:00 pm ET (in person)
It’s easy to make a paper Möbius band: take an ordinary strip of paper, give it a twist, and tape the ends together.  Move the strip around in space, trace your fingers around it, and observe something surprising: while an untwisted paper bracelet has two edges and two sides, surprisingly, the twisted version has only one edge and only one side.  And ponder this: how short of a strip can be used to make one of these?  The answer to this question had been a mathematical mystery until Richard Schwartz, Chancellor’s Professor at Brown University and the author of Really Big Numbers, proved that a one-inch wide strip had to be more than roughly 1.7 inches (the square root of three, to be exact) to do the job.  Join Richard as we hear about some of the ideas that went into his recent proof while also having fun making Möbius bands of various kinds – knotted ones, multi-twisted ones, and the famous optimal one that comes up in his result – and exploring their strange and delightful properties.  Family Fridays is 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.  Thanks to the generous support of Two Sigma, this program is free to attendees.  Register at momath.org/family-fridays.
