Function Phone Cases - iPhone and Android
Description: Rendered on a deep dark background, this artwork presents the complex plane with the critical strip, the critical line Re(s) = ½ and the first nontrivial zeros of the zeta function, above ζ(s) = Σ 1/nˢ. In 1859 Bernhard Riemann conjectured that all nontrivial zeros of the zeta function lie on the line Re(s) = ½. The Riemann hypothesis, linked to the distribution of prime numbers, is still unproven today. Made for math teachers, mathematicians and students who love an elegant proof, it brings classic mathematics to a classroom, study or home office.
