Bernhard Riemann
Bernhard Riemann was a German mathematician who made significant contributions to the fields of Differential Geometry, Number Theory, and Mathematical Physics. He is best known for his work on the Riemann Hypothesis, a problem that deals with the distribution of Prime Numbers. Riemann's work on Manifolds and Riemannian Geometry laid the foundation for Albert Einstein's theory of General Relativity. His ideas also influenced the development of Topology and Functional Analysis. Riemann's contributions to mathematics have had a lasting impact on our understanding of Space and Time.
