Mathematicians solve 75-year-old mystery of infinite loop’s shape.

Eugene Starostin’s desk is littered with rectangular pieces of paper. He picks one up, twists it, and joins the two ends with a pin. The resulting shape has a beautiful simplicity to it — the mathematical symbol for infinity () in three-dimensional form. “Look,” he says, as he traces his finger along its side, “whatever path you take, you always end up where you started.”
