David Hilbert: Hilbert has played a great role in many fields of mathematics, including geometry, number theory, logic and mathematical physics. 1900 put forward the famous "Hilbert problem", which influenced the direction of mathematical research in the following years.
2. Albert Einstein: 1905, his special theory of relativity shocked the world. 10 years later, his general theory of relativity shocked the world again.
3. leonhard euler: Euler initiated graph theory and topology, and his names can be seen everywhere in mathematics: Euler number, Euler identity and euler theorem.
4. Carl. Friedrich? Gauss: From prodigy to "mathematician prince", Gauss inherited Euler's legacy and influenced almost all fields of mathematics.
5. isaac newton: Undoubtedly, during the out of the dark era in Europe, the law of motion made a great breakthrough in our understanding of the physical world.
Bernhard Riemann, another German genius, pioneered Riemannian integral in analysis, Riemannian manifold in geometry and Riemannian Zeta function in number theory. Riemann conjecture is one of the most famous unsolved problems in mathematics today.
