Free Math Encounters: “Error-Correcting Codes: The Mathematics of Communication” featuring Nathan Kaplan (in person/online)
Wednesday, July 13 at 4:00 pm and 7:00 pm ET (New York)
Suppose we are trying to communicate over a “noisy channel.”  There is some probability that the information I send is not the information you receive.  We could communicate more reliably by agreeing to repeat the intended message multiple times, but there is a cost to this repetition.  A major goal in the theory of error-correcting codes is to understand how to efficiently build redundancy into messages so that we can identify and correct errors.  Join mathematician Nathan Kaplan as he introduces us to the ideas that go into the mathematics of communication and shares several neat examples of problems we can solve using ideas from coding theory, including “Hat Problems,” “Twenty Questions with Lies,” and strategies for gambling on soccer matches in Finland.  Special introduction by Tony Fisher, Principal, Hunter College High School.  Math Encounters is MoMath’s popular free public presentation series celebrating the spectacular world of mathematics, produced with support from the Simons Foundation.  Learn more and register at mathencounters.org.

Volumes, the MoMath book club: a discussion of The Jazz of Physics by Stephon Alexander (online)
Wednesday, July 20 at 6:30 pm ET (New York)

More than fifty years ago, John Coltrane drew the twelve musical notes in a circle and connected them by straight lines, forming a five-pointed star.  Inspired by Einstein, Coltrane put physics and geometry at the core of his music.  Physicist and jazz musician Stephon Alexander follows suit, using jazz to answer physics’ most vexing questions about the past and future of the universe.  Following the great minds that first drew the links between music and physics — a list including Pythagoras, Kepler, Newton, Einstein, and Rakim — The Jazz of Physics reveals that the ancient poetic idea of the “Music of the Spheres,” taken seriously, clarifies confounding issues in physics.  Learn more and register at volumes.momath.org.

Relaxing and meditative, constructing polyhedra is like yoga for your hands.  Each week we’ll make new polyhedra and show off what we’ve made the week before, working through many of the usual suspects, and then beyond into stellations, compounds, space fillers, and more.  PDF templates will be available to download and print onto cardstock or drawing paper.  For this final session of the series, we’ll have a culminating, in-person Polyhedra Party in the Museum to show off our best models, with prizes!  Hosted by mathematician and artist Chaim Goodman-Strauss.  Learn more and register at polyhedraparty.momath.org.

Add a little math to your summer!  MoMath is pleased to present the NYC Math Festival, providing a full day of math fun in the sun for all ages.  Bring your friends and the entire family to Fosun Plaza at 28 Liberty St. and enjoy hands-on math exhibits, entertaining mathematical games, and intriguing puzzles and brainteasers.  Plus, take home a little bit of MoMath: we’ll be setting up an outpost of Additions, the shop at MoMath, for all your summer gift needs.  No registration needed.  Learn more at nycmathfestival.momath.org

Modular Mondays (online)
Monday, August 22 at 4:30 pm ET (New York)
Folding Fridays will become Modular Mondays for the months of July and August.  Modulars are magnificent mathematical models that are made of many easily foldable units, which are then assembled together to form the final shape.  The individual units look different from the final model, making the assembly a fun puzzle that challenges your hand-eye coordination and hones your spatial reasoning skills and, of course, uses plenty of math.  Satisfying to fold and beautiful to behold, these modulars are a favorite for people of all ages and skill levels.  Learn more and register at modularmondays.momath.org.

Starring Math — discussion of the film WALL•E, hosted by Tim Chartier (online)
Monday, August 22 at 7:00 pm ET (New York)
Math goes to the movies!  Join MoMath’s 2022–2023 Distinguished Visiting Professor Tim Chartier for a discussion of WALL·E, Pixar’s 2008 animated masterwork about a trash-clearing robot left amid the wreckages of civilization long after humans have left Earth.  At once a philosophical quest into the future of the species and an unlikely love story, WALL·E has been treasured by kids and adults alike since its release.  The discussion will address the mathematical breakthrough by Pixar that allowed for complex crowd scenes and how the multiplication principle from combinatorics was behind this advancement.  Learn more and register at starring.momath.org.
