Riemann

Bernhard Riemann was a 19th-century mathematician who made groundbreaking contributions to geometry and analysis. He introduced the concept of a curved space—known as Riemannian geometry—which allows us to understand how space can be smoothly curved, a fundamental idea in Einstein's theory of general relativity. Riemann also developed methods to analyze complex functions and laid the groundwork for modern mathematical physics. His work helps us understand the shape, structure, and behavior of spaces, both familiar and abstract, influencing fields from physics to pure mathematics.
