Dear MoMath friends,

Happy Thanksgiving!

Puzzles and mysteries abound at MoMath…grab your friends and come unravel the mysteries of Leonardo’s Codex, this year’s exciting version of MoMath’s popular Dimensions puzzle hunt.  Then join one of the nation’s foremost experts in mathematical puzzles, Peter Winkler, for an event focused on the challenges, inspiration, enlightenment, and fun that come from solving a great puzzle.  The intrigue continues in 2020 with explorations of a million-dollar mathematical mystery, a century-old tiling puzzle, and an evening of mathematical challenges at the Masters, MoMath’s annual adult math tournament and charitable benefit.  Plus, don’t miss a visit from children’s writer David Schwartz, author of the popular book How Much is a Million?, the return of MoMath favorite Po-Shen Loh for an event focused on the math — and art — of travel, and the final month of Math Unfolded, MoMath’s popular origami show, recently featured in The New York Times.

Statistics for Citizens — a series of three standalone sessions
Tuesday, February 11, 6:30 pm (other standalone sessions offered on January 28 and February 4)

As the presidential elections get closer, it becomes more and more important for well-informed citizens to understand how statistics are used — and especially, how they are misused.  If you’ve ever wondered what “margin of error” really means, this minicourse, led by visiting mathematician Paul Zeitz, is for you.  We’ll start with the basics — no prior math knowledge is assumed — and by the end, you’ll have a very good sense of what terms like normal distributionstandard errorcorrelation coefficient, and linear regression mean and how to use these ideas to face the inevitable uncertainty about the future with confidence.  Come for one session of this minicourse, or sign up for all three.  Learn more and register at citizens.momath.org.
