Dear MoMath friends,

These are unprecedented times.  Recognizing that many friends and supporters are facing significant difficulties, MoMath continues to provide engaging mathematical programming, now online.  Join us virtually to Ask a Mathematiciananything you like!  Take some time to ponder a series of elusive, million-dollar math questions, or to figure out what kinds of engaging math activities are hidden, right in your own home.  With the flagship series Math Encounters now online, everyone can join us this week to learn how to beef up your digital defenses.  And deadlines for two exciting contests are drawing near: teachers, it’s a great time to submit your innovative activities to this year’s Rosenthal Prize for Innovation and Inspiration, and students, if you enjoy sharing your love of math with others, you can win an award through the new Steven H. Strogatz Prize for Math Communication.  Plus, MoMath continues to offer engaging online educator sessions for school groups, children, and families.  Finally, if you’re trying to while away the hours at home, it’s not too late to join thousands of others from around the world and sign up for our weekly puzzle challenge, Mind-Benders for the Quarantined.  From all of us at MoMath to all of you, our very best wishes as we navigate this most difficult of times together.

Due to the current health situation, the Museum is temporarily closed.  Please enjoy the following programs and activities — all now available online.

Math Flash!  A New Look at an Old Problem
Monday, April 6, 6:30 pm EDT (New York)
People have been solving quadratic equations for thousands of years, with millions (or perhaps even billions) of people using a memorized — but not necessarily understood — formula.  Join Po-Shen Loh, social entrepreneur, Carnegie Mellon math professor, and national coach of the USA International Mathematical Olympiad team, as he shares a simple alternative to rote memorization.  As recently described in The New York Times, a sequence of simple steps, components of which have been known for hundreds (or even thousands) of years, can be combined in a retrospectively obvious way, bringing clarity and beauty to the solution of these age-old problems.  Learn more and register at mathflash.momath.org.

Statistics for Citizens, part 4: Regression
Tuesday, April 7, 6:30 pm EDT (New York)

This is an encore session, by popular demand, of the January–February minicourse that wrapped up with an explanation of normal distribution, margin of error, and confidence intervals.  Building on this knowledge, we will examine how statistics analyzes the relationship between two variables — specifically, the technique of linear regression.  If you have always wondered about statements like, “heredity only determines 30% of IQ,” this session is for you.  Note: This is part four of a series, but newcomers are welcome — we will catch you up!  Learn more and register at citizens.momath.org.

Family Fridays at MoMath presented by Two Sigma: “Math Meets Art: Making a Rubik’s Cube Mosaic” with Lauren Rose
Friday, April 10, 6:30 pm EDT (New York)

The Rubik’s Cube is a versatile puzzle whose tactile nature and complexity make it fun and interesting to all ages and experience levels; it can also enhance problem-solving and mathematical skills.  But did you know that Rubik’s Cubes can also be a source of creative and artistic play?  Join mathematician and math educator Lauren Rose as we design and construct beautiful patterns with Rubik’s Cubes.  No previous experience with Rubik’s Cubes is assumed, and anyone between the ages of 9 and 99 will enjoy this unique, hands-on workshop.  Be sure to have a Rubik’s Cube handy!  Thanks to the generous support of Two Sigma, this program is free to attendees.  Register at familyfridays.momath.org.

Games of Little to No Chance, a two-session minicourse
Tuesday, April 14 (second session on April 21), 6:30 pm EDT (New York)

The Joy of Mistakes
Friday, April 24, 6:30 pm EDT (New York)

One of the great things about math — real math, not school math — is that mistakes are not bugs, but features.  Mistakes often lead to new ideas and new ways of thinking about things.  What happens if we add fractions the “wrong” way?  In elementary school, we’d get corrected.  As mathematicians, we enter a world of wonders.  Likewise, a naive algebra mistake called the “freshman’s dream” leads to fantastic mathematical insights.  Join mathematician Paul Zeitz in exploring the joy of mistakes.  Learn more and register at mistakes.momath.org.

The Millennium Problems
Monday, April 27, 6:30 pm EDT (New York)

The seven greatest unsolved problems in mathematics are each worth a cool $1 million!  Learn more about these problems as University of Oxford mathematician Dr. Tom Crawford takes us to the cutting edge of mathematical research.  Don’t miss this engaging, interactive event, featuring a live voting system where the audience chooses the next problem to investigate.  This program is appropriate for adults and for students ages 14 and up.  Learn more and register at millennium.momath.org.

Patterns Are Never Enough
Wednesday, April 29, 6:30 pm EDT (New York)

G.H. Hardy once said, “A mathematician, like a painter or a poet, is a maker of patterns.  If his patterns are more permanent than theirs, it is because they are made with ideas.”  But just finding a pattern is never sufficient — you need to make sure that your pattern is true.  Join Paul Zeitz in an exploration of a variety of situations in which what initially appears to be a beautiful pattern turns out to be just a mirage, and in the process, discover some of the mysteries at the frontier of research mathematics.  Learn more and register at mirage.momath.org

Folding Fun Online with MoMath and OrigamiUSA, for ages 12 and up
Thursday, April 30, 2:00 pm EDT (New York)

Solar Eclipses: Math, Science, and Spectacle
Thursday, May 14, 6:30 pm EDT (New York)

As a veteran of 35 total solar eclipses, 17 annular solar eclipses, and 19 partial solar eclipses, as well as two transits of Venus and 4 transits of Mercury across the face of the Sun, astronomer Jay Pasachoff is uniquely positioned to share recent scientific work related to eclipses, international coordination of observations, and future plans.  What role does mathematics play in predicting eclipses, from the ancient saros observations to Halley’s 1715 map, and from Bessel’s 19th-century equations to today’s web-based zoom-and-click maps?  How do theoretical predictions based on magnetic-field measurements, emission spectra of high ionization lines, and radio observations compare to the high res images available today?  How is math used at the times of transits of Venus and Mercury to find the distance to the Sun? Join us to find out!  Learn more and register at solar.momath.org.

Family Fridays at MoMath presented by Two Sigma: “Sky Spectaculars: Now You See It, Now You Don’t!” with Jay Pasachoff
Friday, May 15, 6:30 pm EDT (New York)

Join Professor Jay Pasachoff, one of three people who have seen more total solar eclipses than anybody else in the world, for an evening celebrating the wonder and delight of observable events in our solar system.  What makes the sun disappear, and what’s the best way to watch it when it does?  Why are some eclipses full and others partial, and what causes an annular (ring) eclipse?  When can we see the next partial and total eclipses in New York, and what other exciting things will be happening in our skies?  Professor Pasachoff, Chair of the International Astronomical Union’s Working Group on Solar Eclipses and a professor at Williams College, takes us on an exciting journey of mathematical discovery, including a demonstration illustrating why solar and lunar eclipses occur just a few times each year.  Register at familyfridays.momath.org.
