Mathematician Richard Evan Schwartz has solved a long-standing problem about Möbius strips, proving the Halpern-Weaver conjecture. He demonstrated that to construct a non-self-intersecting Möbius strip, the paper strip’s aspect ratio must be greater than √3. Schwartz’s solution involved correcting a previous error and using basic geometry, providing an elegant answer to a question that has puzzled mathematicians for decades.
