In the autumn of 1939, a British graduate student named Arthur Stone was trimming American-sized paper to fit his European binder. Bored with the leftover strips, he began folding them into triangles. What he discovered wasn't just a toy, but a gateway into a world where paper behaves like a higher-dimensional object. This discovery eventually became the centerpiece of Martin Gardner’s first book , Hexaflexagons, Probability Paradoxes, and the Tower of Hanoi . The Hexaflexagon: More Than Meets the Eye

To mathematicians, these aren't just parlor tricks; they are a study in —the branch of math concerned with the properties of space that remain preserved under continuous deformation. A hexaflexagon is essentially a Möbius strip with extra twists, folded into a flat plane. Probability Paradoxes: When Logic Fails In the autumn of 1939, a British graduate
