Description: Golden ratio value, the number defining beauty, and used in many fields, from math and design to architecture

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.

Description: The Riemann zeta function and its critical strip, with the nontrivial zeros all found on the line where the real part is one half. For mathematicians, number theory fans and math geeks.

Description: A colorful mind map detailing branches of mathematics. The central topic 'MATH' connects to 'ALGEBRA', 'GEOMETRY', 'CALCULUS', 'LOGIC & DISCRETE MATH', 'NUMBER THEORY', and 'STATISTICS & PROBABILITY'. Each main branch further expands into sub-topics with descriptive labels.
