MoMath November – December 2025 Upcoming Events

Dear MoMath friends,

This season let math take the spotlight — leaping, glowing, puzzling, and even nibbling its way into your imagination. Discover how data and math are transforming athletic performance, turning every stroke and split second into a story of precision and possibility; marvel as math and magic collide in a whirlwind of games and clever tricks that make logic feel like sleight-of-hand; and slip through the secret corridors of cryptography, where ancient ciphers inform the modern algorithms guarding today’s digital world. Want to take advantage of the crisp, cool weather? Grab some friends and step outside for the first in a series of MoMath puzzle hunts, roaming the neighborhood as you solve brain-bending challenges, then reconnecting as you warm up with new friends and old over hot chocolate at the Museum. And as we move into the holiday season, don’t miss Light Echoes, a radiant new gallery show featuring sculptural elements that light up with color, motion, and multidimensional math. Finally, satisfy both curiosity and your sweet tooth with Nim and Nibbles, where chocolate, candy, and clever strategy prove that play and problem-solving make a perfect pair. From puzzles to precision and from codes to confections, MoMath invites you to see — and savor — the infinite joys of mathematics in motion.

Wednesday, November 5, at 4:00 pm and 7:00 pm ET (in person)
How does “Attack at dawn” become “Buubdl bu ebxo”? From Caesar’s shift cipher to the algorithms guarding your bank logins, codes span the trivial to the nearly unbreakable. Mathematician Jim Kraft charts that journey, echoing Bruce Schneier’s line that there are “two kinds of cryptography in this world: cryptography that will stop your younger siblings from reading your files, and cryptography that will stop major governments from reading your files.” Come see where history’s favorite secrets land on that spectrum, and why true secrecy is never simple. Special introduction by Leon Tatevossian, Adjunct Professor (Quantitative Finance), NYU; Lecturer (Quantitative Finance), Columbia University. Math Encounters is MoMath’s popular free public presentation series celebrating the spectacular world of mathematics.
