Online 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 today!

Free-to-members Puzzles That Weren’t Used in Mind-Benders for the Quarantined — But Maybe Should Have Been!
Monday, March 1, 6:30 pm ET (New York)

Why would we not use a puzzle?  Perhaps we thought it was too hard, or too easy.  Or hard to state, or to solve, in print.  Or too controversial.  Or not “mathematical” enough.  But some subscribers especially like easy puzzles, others hard ones, and many subscribers have proved that they love to argue.  So let’s talk about some of these rejected puzzles — and while we’re at it, puzzle suggestions from subscribers are always welcome!  Learn more and register at vetoed.momath.org.

Free Math Encounters: “Beating COVID-19: How mathematics and game theory can help us understand the pandemic” with Chris Bauch
Wednesday, March 3, 4:00 pm and 7:00 pm ET (New York)
Mathematical modeling has come to the forefront during the COVID-19 pandemic, but how do these models work?  Join Dr. Chris Bauch, Professor of Applied Mathematics at the University of Waterloo, as he sketches the mathematics behind “flattening the curve” and herd immunity.  Learn why flattening the curve reveals an interplay between disease spread and population behavior and how members of the population can be viewed as engaging in a strategic interaction with one another — a “game” — that determines the trajectory of the epidemic.  Take part in an audience participatory example, illustrating how these interactions can be analyzed mathematically using game theory — and how math really can help us emerge victorious.  Special introduction by Julie Gerberding, former director of the CDC and current Executive Vice President and Chief Patient Officer at Merck.  Learn more and register for free at mathencounters.org.

Ask a Mathematician — Anything!
Thursday, March 4, 4:00 pm ET (New York)
Ever wanted to ask a mathematician something, maybe about a curious new idea you have, or a concept you’d like to understand better?  Don’t know whom to ask?  Here’s your chance!  MoMath’s 2020-2021 Distinguished Visiting Professor Alex Kontorovich will host this one-hour, online session.  Learn more and register at askmath.momath.org.

Jump-In Geometry: “Inversion”
Thursday, March 4, 6:30 pm ET (New York)

Avian Arithmetic: The mathematics of bird flight
Friday, March 5, 6:30 pm ET (New York)
Many of the secrets of bird flight remain to be unlocked despite centuries of study.  Ornithology has traditionally been an empirical science, but various branches of applied mathematics have proven helpful in the understanding and modeling of this complex locomotor behavior.  Led by bird photographer and author Peter Cavanagh, we’ll take a quick tour of the basic anatomy and biomechanics of bird flight, then discover where math fits into the puzzle.  How does body size relate to flight speed?  How can we use computational fluid dynamics to understand lift production in hovering hummingbirds, entropy to provide insight into flocking behavior, proportional navigation to study the pursuit of prey, and trigonometry to generate bird art?  We’ll also touch on the transfer of some of this learned information to the design of bioinspired flying machines in this delightful exploration of the math of bird flight.  Learn more and register at avian.momath.org.

Senior Sessions: “Vote Counts: Packing and Cracking”
Monday, March 8, 2:00 pm ET (New York)

Pi Day 2021: “Probably Pi?”
Sunday, March 14, 2:00 pm ET (New York)

While it is impossible to write pi in its entirety, various methods exist to generate better and better approximations.  In this crowd-sourced experiment, we see how the law of large numbers lets us confidently approach pi by using probability.  By randomly dropping a needle onto a set of lines, we can converge on pi experimentally, without the need for direct measurement.  Come help us generate data to see how many digits of pi we can get — the more, the mathier!  Learn more and register at piday2021.momath.org.

Pi Day 2021: “What is the value of Pi?”
Sunday, March 14, 2:30 pm ET (New York)

Throughout history, people have tried to compute the exact value of pi.  Ancient Babylonians believed that pi = 25/8, Egyptians thought that pi = (16/9)^2 = 256/81, while the Indiana state legislature almost passed a bill in 1897 stating that pi = 3.2.  We know now that pi cannot be computed exactly; join us as we use geometric constructions to find rational approximations.  Learn more and register at piday2021.momath.org.

Free Math Encounters: “Matchings and Couplings: Domino tilings of a chessboard and other tales” with Dana Randall
Wednesday, April 7, 4:00 pm and 7:00 pm ET (New York)
Covering a chessboard with dominos might sound like a curious blend of old pastimes, but in reality these tilings reveal rich and beautiful mathematical structures.  Interesting patterns can be found in the geometric arrangements of dominos, as well as in the numerical counts of tilings of chessboards and related regions.  Alternatively, viewing each domino on the chessboard as pairing a black square with one of its neighboring red squares, tilings can be interpreted as assigning 32 pairs.  Viewing these “matchings” in a variety of contexts, Georgia Tech ADVANCE Professor of Computing Dana Randall shares a surprising array of applications, from the physics underlying collections of diatomic molecules to dating algorithms for forming couples in a community.  Learn more and register for free at mathencounters.org.

Bending Lines
Tuesday, April 13, 6:30 pm ET (New York)
Bending Lines is a story of obsession, of vision, and of the enduring conversation between art and science.  It uncovers the aged Robert Wiggs, an amateur mathematician, obscured by time and his profession, whose artistic work communicates the universal quest to discover the essence of the natural world.  Never formally trained in mathematics, Wiggs looks back on a lifelong obsession with patterns in nature that helped him create a sculptural geometric system that rivaled the work of academic mathematicians, and eventually led him to scientific discovery.  The film had its world premier at the Full Frame Documentary Film Festival in 2018 and has since gone on to screen throughout the world at conferences and festivals with a high focus on art, intellectual curiosity, nature, and mathematics.  An exclusive screening of the film (82 minutes) will be followed by a panel discussion featuring Allison and Peter DeHart, the film’s directors; Calvin Wiggs, geologist and son of Robert Wiggs; and Carlo Sequín, UC Berkeley physicist, computer scientist, and mathematical artist.  Learn more and register at bending.momath.org.

Tween Primes, the MoMath book club for tweens and teens: Navigating Early by Clare Vanderpool
Sunday, April 18, 5:30 pm ET (New York)
At the end of World War II, Jack Baker, a landlocked Kansas boy, is suddenly uprooted after his mother’s death and placed in a boys’ boarding school in Maine.  There, Jack encounters Early Auden, the strangest of boys, who reads the number pi as a story and collects clippings about the sightings of a great black bear in the nearby mountains.  When the boys find themselves unexpectedly alone at school, they embark on a quest on the Appalachian Trail in search of the great black bear.  But what they are searching for is sometimes different from what they find.  They meet truly strange characters, each of whom figures into the pi story Early weaves as they travel, while discovering things they never realized about themselves and others in their lives.  Learn more and register at tweenprimes.momath.org.
