C.F.Gauss (1777- 1855) is known as the prince of mathematics. /kloc-at the age of 0/4, one of the greatest mathematicians in human history discovered Gaussian series. 15 years old began to seek non-Euclidean geometry and finally found out how intrinsic geometry was extended to higher dimensions by his disciple Riemann, who discovered the famous Riemann geometry at the age of 18 years old. The famous least square method, 19 years old, solved the problem of ruler drawing of regular polygons that has not been solved for more than 2000 years, and extended it to completely solve the problem of ruler drawing of regular polygons. This year, he began to write that famous diary until he was 27 years old. There are 144 important discoveries, including the bi-periodic nature of elliptic functions (he was less than 20 years old at this time) and so on. The landmark masterpiece Arithmetic Research, which was completed at the age of 24, formally created number theory, in which the reciprocal ratio was proved in six ways, the quadratic theory was developed, the concept of congruence was put forward, and the rigor of analytic number theory was created. If Goss Abel, jacoby and others can see that day, it will also begin. Remember that they don't have to spend their most youthful years on the achievements discovered by Gauss, mathematics will progress for at least a century, and those discoverers of non-Euclidean geometry can also make greater contributions. Gauss's work involves number theory algebra (gauss elimination), complex variable function theory, non-Euclidean geometry hypergeometric series, elliptic function astronomy geodesy electromagnetism, potential theory, surface theory, probability statistics and so on.
