The universe is very big and the particles are very small ... under what circumstances did Hua say this?
As early as May 1959, the famous mathematician Hua published the article "Great Mathematics for Use" in People's Daily. This sentence comes from this. This article is now included in the book "Great Mathematics for Use" and can be consulted.

The original sentence is "the universe is big, the particles are tiny, the speed of rockets, the cleverness of chemical engineering, the change of the earth, the mystery of biology, the complexity of the sun and the moon, and mathematics is everywhere." It means that the application of mathematics in various fields of real life plays a vital role in people's life and development.

China's scientific research achievements:

1. The international mathematical research achievements named after Fahrenheit include Fahrenheit theorem, Huai-Hua inequality, Fahrenheit inequality, Lawwill-Gardner theorem, Fahrenheit operator, Hua-Wang method, etc.

In the 1940s, the historical problem of Gaussian complete triangular sum estimation was solved, and the best error order estimation was obtained. The research results of G·H· Hardy and J·E· Littlewood on the Welling problem and E Wright on the Tali problem have been greatly improved, and the research results of trigonometry are called "Fahrenheit Theorem" by the international mathematical community.

3. In algebra, the basic theorem of one-dimensional projective geometry left over from history is proved. This paper gives a simple and direct proof that the normal child of an object must be contained in its center, which is Hua theorem.

4. In cooperation with Professor Wang Yuan, he has made important achievements in the application research of modern number theory methods, which is called "Hua Wang Fa". 1956 won the first prize of the first national natural science award. 1990 and Wang Yuan * * * both won the Chen Jiageng Prize for Materials Science.
