While at Maker Faire New York, I happened upon this mathematically magical way to cut a bagel, as shown by George Hart of the Museum of Mathematics.
It was a little hard to follow even seeing it in person. Luckily, there are detailed instructions on the Museum of Mathematics website. Here’s a helpful hint: The motion of the knife follows the surface of a two-twist Möbius strip. Of course!
So cut a bagel for someone you love today, because nothing says “I love you” like two intertwined, congruent bagel halves.
And now I’ve gone to the Museum of Mathematics website and can’t wait to make some of these projects with my students!!!
