MoMath September – October 2024 Upcoming Events
Dear MoMath friends,
Let’s get logical with David Reimann, MoMath’s 2024–2025 Visiting Professor for Public Outreach, as he kicks off his tenure with a series of September events focused on logic. AI is in the air this fall as well, with sessions on the math of artificial intelligence, math in the 21st century, and an introduction to Lean, a programming language that can prove mathematical theorems. For those with a more artistic bent, tie math to needlework with the return of the runaway hit Topological Crochet, explore how math is behind the digital enhancement of photos, and create beautiful origami every week at Folding Fridays with fellow origami enthusiasts of all ages and backgrounds. Plus, it’s that time of the year: MoMath’s annual gala is just around the corner, literally (now at 225 Fifth Avenue) as well as figuratively (coming up this October 15). Make a $55 donation to the gala — math’s most fashionably fun event of the year — and you’ll be entered into a lottery to win a free seat at the MoMath gala table!
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. Purchase admission tickets at momath.org/visit, or become a member at momath.org/join to enjoy a year of unlimited general admission, plus an array of benefits.

The Mathematics of AI: From the simplest case to detecting cats, featuring Samuli Siltanen
Thursday, September 19, from 6:30 pm to 7:30 pm ET (in person)
Artificial intelligence is breaking new ground every week. It writes essays, drives cars, and identifies dogs, cats, and bicycles from photos. Much of this is based on neural networks, which coarsely mimic the brain. Take a closer look at the computations behind AI in this presentation led by Samuli Siltanen, Professor of Industrial Mathematics and Vice Dean of the Faculty of Science at the University of Helsinki, Finland. Amazingly, we will see that neural networks use only elementary school math to work their magic, that orienteering strategies have implications on learning, and that the automatic “learning” that AI code does is akin to a mountaineer looking for the lowest valley in thick fog.

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.

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.
