Bernhard Riemann

Georg Friedrich Bernhard Riemann

Bernhard Riemann (17 September 1826 – 20 July 1866) was a German mathematician who made significant contributions to analysis, differential geometry, and the foundations of modern mathematics. His work on the Riemann Hypothesis, the Riemannian geometry, and the Riemann integral has had a profound impact on various fields of mathematics and science, influencing theories and applications in physics, number theory, and beyond.

Early Life and Education

Bernhard Riemann was born in Breselenz, a village in the Kingdom of Hanover (now part of Germany). He was the second of six children in a poor Lutheran pastor's family. Riemann showed an early inclination towards mathematics, and with the support of his family and teachers, he went on to study at the University of Göttingen and the University of Berlin. At Berlin, he was influenced by the teachings of Carl Friedrich Gauss, Peter Gustav Lejeune Dirichlet, and Jakob Steiner.

Contributions to Mathematics

Riemann's contributions to mathematics are vast and varied. Some of his most notable works include:

Riemann Hypothesis

The Riemann Hypothesis is one of the most famous and longstanding unsolved problems in mathematics. Proposed in 1859, it concerns the distribution of the zeros of the Riemann zeta function and has deep implications in number theory, particularly in the distribution of prime numbers.

Riemannian Geometry

Riemann laid the foundations for Riemannian geometry, a branch of differential geometry that deals with curved spaces. His ideas on this subject have been instrumental in the development of general relativity and have influenced various branches of mathematics and theoretical physics.

Riemann Integral

The Riemann integral is a fundamental concept in the field of analysis, providing a rigorous formalization of the process of integration. It has been superseded by the Lebesgue integral in many applications, but remains an important concept in the understanding of integration.

Later Life and Legacy

Riemann's health was always fragile, and he suffered from various illnesses throughout his life. He died of tuberculosis in Selasca, Italy, at the age of 39. Despite his short life, Riemann's work has had a lasting impact on mathematics. The Riemann-Roch theorem, Riemann-Hurwitz formula, and Riemann surfaces are just a few examples of concepts named after him that continue to be central in mathematical research.

Riemann's ideas have transcended mathematics, influencing fields such as quantum mechanics, string theory, and cosmology. His ability to think abstractly and introduce new concepts that at first seemed counterintuitive has made him one of the most influential mathematicians of the 19th century.
