🪢 What do ropes, rings, and rubber bands have to do with mathematics?

Join Dr. Tiago Hirth at Family Fridays: “Loops, Links, and Clever Illusions” on Friday, June 5, from 6:30 pm to 8:00 pm at MoMath.

Through hands-on activities and mind-bending demonstrations, explore the mathematics of knots, links, topology, and the famous Borromean rings. Discover how simple objects can reveal surprising mathematical ideas — and a few clever illusions along the way!

Family Fridays brings together children and adults for engaging mathematical experiences designed to spark curiosity, creativity, and fun for all ages.

Thanks to the generous support of Two Sigma, this program is free.

Fold your way into a mathematical adventure. 🐘📐

This week at Folding Fridays, MoMath’s online origami series, create an elegant Elephant by Fumiaki Kawahata — a striking model that comes to life in the final step, when the body is gently puffed into realistic three-dimensional form.

Every Folding Fridays session features a different model, so you can join anytime and explore the beautiful mathematics hidden in paper folding — symmetry, geometry, structure, and creativity in every crease.

🗓 Friday, May 22
⏰ 4:30–5:30 pm ET
💻 Online

Appropriate for adults and children ages 7+ with prior origami folding experience (the pace moves quickly!).

Materials:
📄 Several sheets of square paper (5.5”–8.5”)
📄 Origami paper preferred (or cut your own)
📄 A few sheets of copy paper may be helpful
