David Hilbert

David Hilbert (German: David Hilbert, January 23, 1862 - February 14, 1943), a German mathematician, was one of the most influential mathematicians in the late 19th and early 20th centuries, and is known as the "Father of Modern Mathematics." Hilbert was born in Königsberg in 1862. He was respected as a great mathematician for proposing a large number of ideas (such as invariant theory, axiomatic geometry, Hilbert spaces). He later succeeded Felix Klein and built the University of Göttingen into a world center of mathematics. Later, under the impact of the Nazi regime, the University of Göttingen lost a large number of talents and its glory collapsed. In 1943, the melancholy Hilbert died in Göttingen, Germany. He proposed the theory of Hilbert space, which is one of the foundations of functional analysis. He enthusiastically supported Cantor's research on set theory and transfinite numbers. A series of problems he raised at the International Congress of Mathematicians in 1900 (Hilbert's 23 problems) pointed out the direction for many mathematical studies in the 20th century. Hilbert and his students made important contributions to forming the mathematical foundations of quantum mechanics and general relativity. He was also one of the founders of proof theory, mathematical logic, and the distinction between mathematics and metamathematics. Hilbert is also a well-known mathematics educator, known for his vivid lectures and appropriate examples.
