This sentence is a famous saying of the great Russian scientist Pavlov. The great thing about it is that this sentence has been successfully implemented by most scientists. For example, academicians such as Luo Peilin, Zhang Wei, and Zhang Guangdou in the early years, and now Yuan Longping, Zhong Nanshan, Li Lanjuan, etc., all have put this sentence into practice in themselves. They continue to contribute to science, and even plan to sacrifice their lives.

1. Luo Peilin

Luo Peilin is one of the academicians of the two academies. He has experienced many things in his life. He met Qian Xuesen in 1933. It was Qian Xuesen who told him that studying could not truly save the country. Luo Peilin is a famous electronics scientist in my country. In 1978, the country did not have an engineering academy. Based on the premise of the development of other technologies, he jointly made suggestions with other academicians, which ultimately led to the establishment of the Academy of Engineering. Because at that time he discovered that in the co-optation of academicians of the Academy of Sciences, many accomplished experts were not allowed to enter, and these experts were all engineering and technical workers. Yuan Longping, the recognized father of hybrid rice at that time, also failed to enter the Academy of Sciences. In order to promote the development of engineering and technical sciences, the Chinese Academy of Engineering was formally established.

2. Yuan Longping

Many people may not know that the father of hybrid rice, who was born in 1930, is now 90 years old. But he still has not retired and is still fighting on the front line of the project. Like many old academicians, they are all engineering and technical workers, and only the front line is their real position. There are many people like Mr. Yuan, such as Zhong Nanshan and Li Lanjuan, who stood up during this epidemic. They are not too young. If it hadn't been for this epidemic, who would have known that they were still fighting on the front line, fighting for the people and the country.

3. A profession worth a lifetime

Scientist is a profession worth a lifetime. Many scientists have fought hard until they were unable to do so, from when they first joined to when they had to leave. They contribute to people in different fields, but they all have the same purpose, which is to make the country strong and the people to live a good life.
