The Museum of Math, Shapes That Roll, and Mime-matics

Welcome to this week’s Math Munch!  We have so many exciting things to share with you this week – so let’s get started!

Something very exciting to math lovers all over the world happened on Saturday.  The Museum of Mathematics opened its doors to the public!

MoMath entranceThe Museum of Mathematics (affectionately called MoMath – and that’s certainly what you’ll get if you go there) is in the Math Munch team’s hometown, New York City.

Maybe you don’t live in New York, so you won’t be able to visit the museum anytime soon.  Or maybe you want a little sneak-peek of what you’ll see when you get there.  In any case, watch this video made by mathematician, artist, and video-maker George Hart on his first visit to the museum.  George also worked on planning and designing the exhibits in the museum.

We got the chance to interview Emily Vanderpol, the Outreach Exhibits coordinator for MoMath, and Melissa Budinic, the Assistant Exhibit Designer for MoMath.  As Cindy Lawrence, the Associate Director for MoMath says, “MoMath would not be open today if it were not for the efforts” of Emily and Melissa.  Check out Melissa and Emily‘s interviews to read about their favorite exhibits, how they use math in their jobs for MoMath, and what they’re most excited about now that the museum is open!

One of my favorite skits, in which the mime really does help you to visualize the invisible world of math, is the Infinite Rope.  Check it out:

Tim and Tanya kindly answered some questions we asked them about their mime-matics.  Check out their interview by following this link, or visit the Q&A page.

Bon appetit!
