Any attempt to better understand Möbius strips is bound to run into some kinks. The twisted loops are so strange that mathematicians have struggled to answer some basic questions about them. For ...

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 ...

Möbius strips are curious mathematical objects. To construct one of these single-sided surfaces, take a strip of paper, twist it once and then tape the ends together. Making one of these beauties is ...
