2. Euclid: the ancestor of Euclid geometry, who wrote The Elements of Geometry.
3. Archimedes: Write out the calculation methods of surface area and volume in geometry, including the calculation of spheres and cylinders, spirals, sand and the balance of figures.
Zu Chongzhi: He founded "Da Li Ming" and calculated pi to seven decimal places.
5. Descartes: In the development of mathematics, he and Fermat jointly founded analytic geometry, which made mathematics enter the first important era-the variable era. He also discovered the relationship between the edges, vertices and surfaces of convex polyhedron, which was later called Euler-Descartes formula. He also discovered the Cartesian branch line, which is common in calculus.
6. Leibniz: Together with Newton, he discovered calculus, which made mathematics enter the second important era and put forward many mathematical symbols. He is a master of mathematical symbols.
7. Euler: put forward the concept of function, founded analytical mechanics, solved the problem of the seventh bridge in Koenigsberg, gave Euler formula, and was the founder of topology.
8. Gauss: Up to now, the greatest mathematician has discovered several theorems that were discovered later (later generations saw them in his notes), and independently studied the theorems discovered by predecessors without seeking fame and fortune.
9. Riemann: the founder of Riemann geometry of non-Euclidean geometry.
10, Hilbert: one of the founders of proof theory, mathematical logic and the difference between mathematics and meta-mathematics, invented and developed many ideas.
