Qian Xuesen s xiaoshihou story

1. A 96-point hydraulics exam paper.

In the library of Jiaotong University, there is a 96-point hydraulics test paper, and the person who made this test paper is Qian Xuesen. After such an ordinary test paper, there is a touching story. It turned out that when Qian Xuesen was studying at Shanghai Jiao Tong University, he was excellent in character and learning, and scored more than 90 points in all subjects.

In a hydraulics exam, Qian Xuesen answered all 6 questions correctly, and his teacher, Mr. Jin, was very happy and gave Qian Xuesen a perfect score of 100 points. However, Qian Xuesen found that he mistakenly wrote a symbol "ns" as "n" when answering the question. Qian Xuesen took the initiative to tell the teacher about this small mistake, and the teacher also put the 100-point test paper as 96 points.

The teacher, Mr. Jin, has always kept the test papers of his beloved apprentices, even in the suitcase during the war-torn migration. When Qian Xuesen returned to his alma mater in the 80s of the last century, Mr. Jin took out this precious test paper and gave it to his alma mater. This small test paper also reflects a world-famous scientist's strict requirements for himself, meticulous and honest in his studies and scientific research.

On October 1, 1949, the founding of the People's Republic of China made Qian Xuesen, who lived in the United States, excited, and after more than 10 years of hard preparation, it was finally time to serve the motherland. He said to his wife, Jiang Ying: "The motherland has been liberated, and we should go back." ”

In order to cultivate more senior talents, the Chinese Academy of Sciences founded the University of Science and Technology of China. The department of the University of Science and Technology of China is corresponding to the research institute of the Chinese Academy of Sciences, and Qian Xuesen is the director of the Institute of Mechanics, so he has been the head of the Department of Mechanical Sciences of the Chinese Academy of Sciences for about 20 years.

Everyone knows that Qian Xuesen's teaching is particularly strict. One exam was an open-book exam. There are a total of two wheel questions, the first is the basic question, and the second question is the calculation question.

From eight o'clock in the morning, the exam continued in the evening. The result is that 95% of people fail, and everyone knows this.

I don't know much about a follow-up, Qian Xuesen is particularly dissatisfied with this result. Qian Xuesen thought that their mathematical foundation was unqualified, and gave them another half a year to postpone their graduation. During this half year, they studied mathematics, physics, and mechanics.

Some people recalled that in the past six months, they have done more than 3,000 more math problems, laying a solid foundation for future scientific research.

In the present, this is hard to imagine. A department chair can make a student graduate half a year late. This is probably also a manifestation of elite education. Today's university education can only be regarded as an assembly line operation.

2. In three difficult years. Qian Xuesen's life is also very sad. But there is one thing that is particularly surprising in it, during the three-year difficult period, he wrote two books and received a remuneration of 3,000 yuan.

This is a huge amount, Qian Xuesen's salary at that time was 300 yuan a month, which is equivalent to his ten months' salary. For most Chinese, it may be a ten-year income. In the 70s, in the richest rural areas in the south of the Yangtze River, the family's annual income may be more than 200 yuan.

Time passes. If you want to publish two books like this now. I guess that Qian Xuesen needs to come up with 30,000 yuan or even 300,000 yuan to publish. What does this mean?

Is knowledge worthless? No, maybe it's the other way around. Because, in the original words, people with knowledge are willing to share their knowledge, and they are famous and profitable.

But now, he who has knowledge is not very willing to share, because he has neither fame nor profit. It is more difficult and costly for ordinary people to acquire knowledge. Effective knowledge will become more expensive in terms of the total cost to society.

In this life, I will never go to the United States again.

Qian Xuesen left the United States in 1955 and never returned. Qian Xuesen was very friendly to his American friends and scientific colleagues and kept in touch, but he insisted that as long as the United States did not formally apologize for "expelling" him from the country that year, he would never go to the United States again in this life.

First as Dean and then as Vice Dean.

On Qian Xuesen's resume, there are often the words "vice president and president of the Fifth Academy of National Defense", but in fact, Qian Xuesen was the first president and then the vice president. Why is that? Although President Qian, who was 45 years old at the time, was full of energy, he not only had to hold a "literacy class" for China's missile industry, but also led everyone to tackle key technical problems, and he also had to worry about firewood, rice, oil, and salt for the whole family at the research institute.

Sometimes, the report of the graduate school and the report of the kindergarten will await his approval. He said, "How do I know about kindergarten?" For this reason, he wrote a letter to Nie Shuai, asking him to "retire" and correct himself to become a deputy and concentrate on scientific research and technological research, and his superiors agreed to his request.

In the early winter of 1955, Qian Xuesen, who had just broken through the obstruction of the US authorities and returned to the motherland, came to visit the Harbin Military Engineering Institute. Senior General Chen Geng, the dean, asked him: "Can the Chinese build missiles?"

Qian Xuesen said: "If foreigners can do it, why can't Chinese do it?" Could it be that the Chinese are shorter than the foreigners?!

This sentence determined Qian Xuesen's career in rocketry, missile, and aerospace careers. More than 40 years have passed, and now Qian Xuesen is 90 years old. With his foundational contributions to China's rocket and missile technology, aerospace technology, and even the entire national defense high-tech undertaking, he has written a splendid chapter in the modernization of our army's advanced equipment.
