Math isn’t just about numbers—it’s also about patterns and shapes. One of my favorite shapes is the Möbius strip, a mind-warping surface with only one side. It’s simple to make one: Just take a strip ...

Imagine holding a strip of paper. You give it a half-twist and then tape its ends together. The shape you’re now holding is the ticket to a world where surfaces have only one side and boundaries blur ...

A newly derived set of differential equations provides a numerical solution to the classic question of predicting the shape of a Möbius strip. To explain the notion of a developable strip it will be ...
