The possible energy levels of an electron confined on a plane may embody a solution to the Riemann hypothesis, a nearly 150-year-old problem in mathematics that’s at the heart of the study of prime numbers. The hypothesis says that a certain formula can give only the value zero when calculated at certain points that lie along one of two possible lines on the plane. In this visual representation, some of those points are indicated by the full color wheel.
