Building Beauty: The Harmonograph Art of Ivan Moscovich in Composite, the gallery at MoMath (in person/online)
Closing April 3

This solo show includes almost three dozen original pieces of Ivan’s art — created using his custom-made (and patented) harmonograph — and explores the intersection of the mathematics of Lissajous curves with the aesthetics of beautiful art.  Ivan fashioned the harmonograph, an analog drawing machine that uses pens and pendulums, to generate an incredible variety of elegantly swirling, multi-colored graphic configurations known as Lissajous patterns.  First exhibited at the Institute of Contemporary Arts in London in 1968, the work it produced was acclaimed as the best math art of the time.  Since then, Ivan’s creations have been shown in major exhibitions in locations including Berlin, Basel, Mexico City, Tel Aviv, and San Francisco, with a renewed interest in his work in the last few years.  The show includes two working harmonographs for visitors to explore how the artwork is created and make their own works to take home.  Learn more at composite.momath.org.

Coming this spring!  Traces in Composite, the gallery at MoMath (in person)
Opening Saturday, April 30
Members-only preview and reception on Friday, April 29 at 6:00 pm ET (New York)

Traces reveals the hidden patterns created as objects move through space: the pathways of birds in flight, the oars of a kayaker on a still lake, or even the drum sticks of a jazz percussionist.  Sometimes periodic but always organized, the traces of these movements — revealed by the technologically savvy artists in this exhibit — are as intriguing as they are beautiful.  Take in the stunning visuals, explore the underlying mathematics of the artwork, and create your own patterns using a suite of engaging, hands-on experiences.  Learn more at composite.momath.org.

Desert Island Math: Squares and Cubes (online)
Monday, April 11 at 6:30 pm ET (New York)

Imagine you are stranded on a desert island with just pencil and paper — and one mathematical concept to explore.  Your goal?  To discover as much as you can about that topic.  Join mathematician Paul Zeitz in an adventure combining mindfulness and play as we take a single, simple mathematical idea and look at it from as many perspectives as possible.  Even alone on an island (or during a pandemic), you will never be bored as long as you have math and your imagination!  The operation of squaring — that is, multiplying a number by itself — may seem mundane, but nothing is mundane when you really focus on it.  Join us to see how a few very innocent questions about squaring (and possibly cubing) take us beyond simple arithmetic into surprising branches of mathematics.  While geared toward beginners, these sessions will also contain food for thought for experts.  Learn more and register at desert.momath.org.

Senior Sessions: “Magic Squares” (online)
Tuesday, April 12 at 2:00 pm ET (New York)

Free Math Encounters: “The Lonely Runner: an unsolved mystery of mathematics” featuring Matthias Beck (in person/online)
Wednesday, April 13 at 4:00 pm and 7:00 pm ET (New York)
The Lonely Runner Conjecture is an (in)famous open problem in combinatorial number theory: if n runners with different (constant) speeds move around a circular track of length 1, then for each runner there will be a time when they have distance at least 1/n to the others.  How did this problem come about, how is it related to the approximation of real numbers by rationals, and how can we visualize this problem using two- or three-dimensional shapes?  Join mathematician Matthias Beck as we explore this fascinating mathematical mystery.  Learn more and register for free at mathencounters.org.

Thursday, April 14 at 6:30 pm ET (New York)

Volumes continues!  Join Distinguished Visiting Professor Steven Strogatz for an online discussion of The Calculus of Happiness by Oscar Fernandez.  What’s the best diet for overall health and weight management?  How can we change our finances to retire earlier?  How can we maximize our chances of finding our soul mate?  In The Calculus of Happiness, Oscar Fernandez shows us that math yields powerful insights into health, wealth, and love.  Using only high school–level math (precalculus with a dash of calculus), Fernandez guides us through several surprising results, including an easy rule of thumb for choosing foods that lower our risk for developing diabetes, simple “all-weather” investment portfolios with great returns, and math-backed strategies for achieving financial independence and searching for our soul mate.  Learn more and register at volumes.momath.org.

Desert Island Math: Shortest Distance (online)
Monday, April 18 at 6:30 pm ET (New York)

Imagine you are stranded on a desert island with just pencil and paper — and one mathematical concept to explore.  Your goal?  To discover as much as you can about that topic.  Join mathematician Paul Zeitz in an adventure combining mindfulness and play as we take a single, simple mathematical idea and look at it from as many perspectives as possible.  Even alone on an island (or during a pandemic), you will never be bored as long as you have math and your imagination!  We all know that “the shortest distance between two points is a straight line,” but that’s only true if the points lie on a two-dimensional plane and there are no other constraints.  What if they don’t lie on a plane?  Or what if there are obstructions?  Delve deeply into a few such situations and learn a bit about optimization and non-Euclidean geometries in the process.  While geared toward beginners, these sessions will also contain food for thought for experts.  Learn more and register at desert.momath.org.
