Solstice Poly-Star

On June 20, come out to the Flatiron Plaza at 23rd and Broadway to help MoMath celebrate the mathematical significance of the summer solstice in New York City. There, you’ll learn why, just as a seven-pointed star perfectly suited the winter solstice, a ten-pointed star captures the math inherent in the opposite extreme of the solar year. And this time, MoMath takes the celebration into the third dimension — participants will construct a dozen ten-pointed stars and assemble them into an almost ten-foot-tall geometric structure with remarkable symmetry. Come on your lunch break to help kick off the construction or after work for its culmination (or any time in between); anyone can pitch in, even for just a few minutes, and share in mathematical beauty inspired by the start of summer.
