Praise Deng Jiaxian's words (call Deng Jiaxian committed to the country; There is a spirit)

20 19 12 1, in the CCTV comprehensive channel's "China in the Story" program, you Huaze, a security guard in Deng Jiaxian, recalled that on the last day of Deng Jiaxian's death, he said to his wife Xu Luxi, "If there is an afterlife, I will choose China, the nuclear industry and you!"

Deng Jiaxian's words are full of deep affection for the motherland and love for his wife, as he himself said: "I have no regrets about my life choice!"

Deng Jiaxian

Back to the end of Qing Dynasty, Empress Dowager Cixi declared war on eleven countries. Soon after the fall of Beijing, Empress Dowager Cixi fled to xi 'an and ordered Li Hongzhang, governor of Guangdong and Guangxi, to take full charge of the negotiations. After many negotiations, 190 1 year, Li Hongzhang signed the "Xin Chou Treaty" with foreign powers on behalf of the Qing court. According to the treaty, the Qing dynasty paid 982 million silver to eleven countries as principal and interest, with an annual interest of 4%, which was paid off in thirty-nine years.

Can Qing afford such a large sum of money?

I definitely can't afford it. I lost a few years, and Qing died.

Where did the money go? Germany was defeated after the First World War. Although China sent only a few hundred people to the war at that time, we still won the war and did not need to pay compensation.

What about the money to compensate America? Some of them were returned by the United States. At that time, the United States had a movement to return Geng funds, and the United States was also very entangled. The Qing dynasty is dead, so who should I return the money to?

It was wrong to give it to anyone during the war. To put it simply, the United States established Tsinghua School in China and started education. Later, this Tsinghua school was upgraded to Tsinghua University. At that time, Tsinghua's education funds were the most secure, because the money was controlled by Americans.

Not only that, outstanding graduates from Tsinghua University can also go to the United States to study and provide full scholarships.

Famous scientific giants, such as Qian Xuesen, Mei Yiqi, Hu Shi, Yang Zhenning, Deng Jiaxian, etc. They are all students studying in the United States. Almost all the masters who grew up in the late Qing Dynasty and the early Republic of China were related to Geng Kuan.

As an international student studying in the United States, Deng Jiaxian came to the United States on the other side of the ocean for further study.

1924, Deng Jiaxian was born in a scholarly family, and his father was a famous master of Chinese studies, Deng Yizhe. From 65438 to 0945, Deng Jiaxian graduated from the Department of Physics of National Southwest Associated University and later taught in Peking University. 1948 was admitted to the physics department of Purdue University, USA, and received a doctorate. It took him only two years and he was only 26 years old. So many people call Deng Jiaxian "Doctor Doll".

Deng Jiaxian

After graduating from Ph.D., the tutor Debenhal appreciated Deng Jiaxian's physical talent and hoped that Deng Jiaxian would go to England with him for further study and study nuclear physics, where there were first-class experimental equipment, first-class teachers and first-class scientific research environment. If you stay there, the future of Deng Jiaxian is immeasurable, and the Nobel Prize in Physics is just around the corner.

At this moment, Deng Jiaxian remembered his father's entrustment before he left. When you finish your studies in the future, you must make contributions to the motherland with science. Compared with a Nobel Prize winner, China needed a talented scientist at that time.

So on the ninth day after receiving his doctorate, that is,1August 29th, 950, Deng Jiaxian couldn't wait to board the passenger ship "President Wilson" and set foot on the way home.

1958, Liu Jie, vice minister of the Second Machinery Department, found Deng Jiaxian and secretly said that the country was going to set off "big firecrackers". Do you want to join us? Please keep it secret. Deng Jiaxian replied without thinking: I would like to join.

Later, Deng Jiaxian's wife Xu Luxi recalled, I asked him where he was going to work. He said it was confidential. What job? He said to keep it a secret. What is the address? Is still a secret. I write to you, but I can't. Deng Jiaxian looked at his wife blankly and said, this family will depend on you in the future. I want to dedicate my limited life to my work. If it is done, it is more important than Mount Tai! Xu Luxi could see that Deng Jiaxian's attitude was firm and he didn't say much, so he turned to pack for Deng Jiaxian.

Deng Jiaxian, Xu Luxi and two children.

The next day, Deng Jiaxian packed his bags and embarked on the difficult road of developing firecrackers in obscurity.

It may be a bit wrong to describe the life in Deng Jiaxian after the atomic bomb was developed, but it is basically the same. In 28 years, Deng Jiaxian spent most of his time in the atomic bomb development bases in Qinghai and Sichuan. Occasionally, when he needs to report his work to Beijing, if time permits, he will return to his home in Beijing and reunite with Xu Luxi briefly. Of course, such reunions are rare.

The code name of Big Firecracker is Project 02, and Deng Jiaxian is the director of the Theory Department of Nuclear Weapons Research Institute. The initial task was to train researchers to learn from Soviet experts. After the Soviet experts arrived at the base, they left a lot of feelings, saying nothing about the structure, manufacturing methods and steps of the atomic bomb and the experience of the Soviet Union in manufacturing the atomic bomb. In short, they didn't talk to you about technology at all. Instead, it made it clear that to build an atomic bomb, roads must be built first. There is no road for transporting atomic bombs, so roads are the key. Soviet experts are also talking nonsense. The atomic bomb hasn't been built yet. Let's build roads first. Just like buying a car before driving test. The house hasn't been built yet, so buy decoration materials first.

Deng Jiaxian

But under the circumstances, Big Brother had to keep his word. There is no way. Deng Jiaxian can only take people to Yongding River to fetch sand and build roads. After the road was completed, Soviet experts proposed to build barbed wire on both sides of the road, and they tossed it for half a year. Soviet experts have no knowledge and experience in teaching any atomic bombs, and teaching does not exist. They have been uncles for half a year and have taught nothing.

Later, due to the deterioration of Sino-Soviet relations, the Soviet side withdrew all the experts one after another, leaving no usable atomic bomb drawings and notes. Before he left, he sneered: Without us, you scientists in China are nothing, and you can't build an atomic bomb in 20 years. Khrushchev even said: You didn't even have to wear pants in the end.

In order to remember this special day, under the care and guidance of the state, scientists are determined to make their own "battle bombs" and code the first atomic bomb project as 596.

Facing the cynicism of the Soviet Union, Deng Jiaxian was not discouraged, but strengthened the belief that China scientists could independently build an atomic bomb! Numerous scientists, including Deng Jiaxian and his colleagues, made tens of thousands of calculations under heavy pressure, and it took only three years to knock on the door of China people's independent development of atomic bombs.

Atomic bomb explosion

1964 65438+1October 16 in the afternoon 15, the mushroom cloud expected by the whole country is in full bloom over the northwest. Premier Zhou Enlai said with emotion: "It is doubtful whether we can climb the peak of science and technology by ourselves, not only abroad, but also at home. But with the explosion of China's first atomic bomb, it is time to sweep away all inferiority. " Coincidentally, Khrushchev, who had been cynical about China's atomic bomb before, also despondently stepped down on this day.

As we all know, radiation in nuclear experiments is very harmful to human body, and it is easy to cause cancer in the body. A few days ago, I had a CT scan, and the doctor told me not to have children for six months. Hiroshima and Nagasaki in Japan were bombed by American atomic bombs. They can't live for ten years because of the huge radiation. Think about it. Deng Jiaxian has been on the front line of nuclear tests all the year round, and Deng Jiaxian itself has been exposed to radiation. On one occasion, there was an accident in the hydrogen bomb airdrop test. In order to find out the reason, he resolutely walked into that area and suffered deadly nuclear radiation.

Deng Jiaxian and his wife Xu Luxi were seriously ill.

Of the 32 nuclear tests that have been conducted, Deng Jiaxian personally conducted 15 times, and he can persist in developing nuclear weapons for 28 years. I'm afraid only Deng Jiaxian is still working hard, even suffering from a terminal illness. He fought for nuclear weapons all his life, not only presided over the design of atomic bombs and hydrogen bombs, but also achieved brilliant results one after another, such as the successful development of new hydrogen bombs and the second generation of nuclear weapons.

1985, after Deng Jiaxian personally conducted the last nuclear test, he had to return to Beijing because of extreme physical discomfort and was admitted to the People's Liberation Army 30 1 hospital. At this time, he was in the advanced stage of rectal cancer. Deng Jiaxian showed signs of bleeding and had to be hospitalized. While in hospital, they said to those who came to visit him, "I knew this day would come, but I didn't expect it to come so soon."

This photo was taken when Yang Zhenning visited Deng Jiaxian. Watch the corners of Deng Jiaxian's mouth. There is blood. You know, Deng Jiaxian is suffering from illness at this time, but his smile is very touching.

Xu Luxi recalled: "Deng Jiaxian was very ill at that time. Three months before his death, he struggled with the disease after the operation. From his hospital bed, he drafted an opinion on the development of China's nuclear weapons. He cares about the disposal of nuclear waste and repeatedly reminds people never to be polluted. He expects that after his illness, he will engage in the peaceful use of atomic energy in medicine, agriculture and mining. , benefit the daily life of ordinary people. Leaders, colleagues, friends and relatives failed to keep him. As for Deng Jiaxian's two-bomb bonus, it's really 20 yuan. At that time, the total prize money won by the whole scientific research group was only 10000 yuan, divided into 10 yuan, divided into 5 yuan and 3 yuan, and Deng Jiaxian won the highest prize money, totaling 20 yuan.

1986 On July 29th, a scientific superstar fell, and Deng Jiaxian died of systemic hemorrhage at the age of 62. Before dying, I only said one sentence: I, die without regret. This article refers to the Biography of Deng Jiaxian.

In order to carry forward the prestige of our country, he is willing to be unknown, and in order to strengthen our mountains and rivers, he does not hesitate to commit himself to the country.

There are many great scientists like Deng Jiaxian in China.

Deng Jiaxian resolutely returned to China in the face of numerous obstacles, and many people could not help thinking of Mr. Yang Zhenning. Yang Zhenning did not return to China with Qian Xuesen, but this was not his intention. At that time, he studied cutting-edge physics research, which had little short-term effect after returning to China, but Yang Zhenning was serving the country in another way.

After returning to China, Yang Zhenning participated in the construction of more than 60 national physics laboratories and devoted himself to the teaching of college physics. In 2004, 82-year-old Lao Yang still insisted on teaching undergraduates in Tsinghua University. In Tsinghua University, Yang Zhenning earned an annual salary of 6,543,800 yuan, which he donated to Tsinghua University Advanced Research Center for free. He also sold his mansion in New York, USA, and donated $654.38 million to Tsinghua, from which he established Yang Zhenning Lecture, Yang Zhenning Scholarship and Yang Zhenning Foundation. Zhou, president of Chinese Academy of Sciences, said that at least 10 academicians of Chinese Academy of Sciences and five university presidents have been trained for China. Without Yang Zhenning, there would be no physics department in Tsinghua today.

Yang Zhenning

Why can Yang Can Zhenning achieve such high achievements? Of course, this is inseparable from his excellent math scores! In 1983, when Yang Zhenning introduced his learning process to middle school students, he specifically mentioned a person. He said: "There is a Mr. Liu Xunyu, who is a mathematician and has written many simple and interesting mathematical articles. I remember reading one of his articles about intelligence tests before I knew the extremely important mathematical concepts of permutation and parity. " Liu Xunyu is a famous mathematician and educator in China. He and Yang Zhenning's father are classmates.

How awesome is Liu Xunyu? Let me give you an example.

In the history of China, there was a middle school where there was a god: chunhui middle school.

The art teacher in this school is Feng Zikai.

Music teacher: Li Shutong.

Chinese teachers: Zhu Ziqing and Zhu Guangqian.

Calligraphy teacher: Yu Youren.

In addition, Cai Yuanpei, Jiang Menglin, He Xiangning, Ye Shengtao, Zhang Daqian, Ba people, Liao, Huang Yanpei, Chen Wangdao and others also gave lectures.

Who is the math teacher? It's Liu Xunyu.

Liu Xunbi was very good at mathematics education, and all the masters of Neo-Confucianism in China's time were basically influenced by him.

Therefore, in the field of mathematics education, Liu Xunbi is definitely a master of the Republic of China. Feng Zikai, an art teacher, often asks Liu Xunyu for advice.

Mathematician Gu Chaohao said: I remember reading Liu Xunyu's "Garden of Mathematics", in which there is a paragraph about calculus, starting with what speed is. At that time, I thought I knew the concepts of speed and acceleration very well. But after reading this book, I found that the real concept of speed can only be deeply understood by calculus, so I became more and more interested in mathematics. "

Liu Xunyu's Three Mathematical Works

It can be seen that a good math book can make children fall in love with math. There are three books in this set that I show to the children. One is "Teacher Ma talks about mathematics", which mainly talks about how to solve some four arithmetic problems by graphic method. The second book, Fun of Mathematics, focuses on mathematical problems encountered in daily life. We say that everything is mathematics, and learning mathematics through everything is the fastest. The third book is the Garden of Mathematics, which talks about the concepts of function, continuity, induced function, differential, integral and complete set and the basic principles of their operations. This set of mathematics enlightenment books, which inspired Yang Zhenning and other best physicists in the world, is worth reading by every child. And the price is not expensive, as long as three volumes are 69, they will be mailed home. If you need to join the group, you can order this set of mathematics enlightenment books for the world's best physicists: all three children's mathematics books by Liu Xunyu. The original mathematics can be bought in 69 yuan.
