It is Qian Xuesen's unswerving childlike innocence for 90 years to love his motherland, her language, land and people.
Two months after the outbreak of the Revolution of 1911, Qian Xuesen was born in Shanghai, and the national tragedy became his first memory. In order to save the country, Qian Xuesen, who graduated from middle school, chose engineering as the direction of his life struggle, just like many aspiring young people at that time. 1In the summer of 934, 23-year-old Qian Xuesen completed his major in mechanical engineering at Shanghai Jiaotong University and was admitted to the preparatory class for studying abroad in Tsinghua University. A year later, Qian Xuesen traveled across the ocean to study for a master's degree in aviation at MIT.
With an impulse to win glory for our country, Qian Xuesen got his master's degree in just one year. 1936, Qian Xuesen transferred to California Institute of Technology, and obtained a doctorate in aviation and mathematics three years later. Subsequently, under the guidance and cooperation of his teacher and world mechanic master von Carmen, Qian Xuesen began the research on aerodynamics, solid mechanics, rockets and missiles of high-speed aircraft, participated in a lot of engineering practice, and worked with colleagues to design and develop the first generation missiles for the United States, laying a reliable theoretical foundation for the establishment of the world aviation industry.
Qian Xuesen rose to fame and became as famous a scientist as von Carmen. The US Army invited him to teach rocket and jet technology, and the US Air Force used his jet propulsion as an internal teaching material. From 65438 to 0947, 36-year-old Qian Xuesen became a young full professor at MIT, with a position, reputation and comfortable life that many people dreamed of.
Qian Xuesen was never prepared to live in America for a long time. He clearly knows that this is just a post station in his life, and the distant motherland is his eternal home. During his 20 years in the United States, Qian Xuesen didn't buy a dollar of insurance. He applied the wind tunnel principle to the calculation of windmill power generation, and the selected height is from sea level to 8 kilometers above sea level, which is the natural condition of his motherland, China.
Many years later, Qian Xuesen said, "I spent the first three or four years in the United States studying and the last ten years working. All this is in preparation for doing something for the people after returning home. Because I am from China. "
1948 victory in the liberation of the motherland is in sight, so that he can see that the waiting time has finally arrived! Qian Xuesen was ecstatic and began to prepare nervously for returning to China.
However, the road home is so bumpy.
Harassment and obstruction followed, and the US authorities exhausted all possible means with only one purpose: never let Qian Xuesen return to China, because "he is too precious to be worth three or five divisions in any case."
The imprisonment, house arrest, intimidation, stalking, persecution and attack of the reactionary forces in the United States can not make Qian Xuesen yield, but only arouse a brave and fearless struggle. Facing the unreasonable accusation of the public prosecutor, Qian Xuesen hit the floor and replied: "Knowledge is my personal property, and I will give it to whoever I have the right." "I come from China, and of course I am loyal to the people of China." American newspapers reported that it was not Qian Xuesen who was tried, but the prosecutor!
Under the great pressure of Qian Xuesen's long-term protest and the diplomatic struggle of the motherland, the American authorities had to agree to Qian Xuesen's return to China. 1955 September 17, Qian Xuesen boarded the ship returning home with rich knowledge and enthusiasm.
The motherland has opened a warm embrace to Qian Xuesen. Guangzhou, Shanghai, Hangzhou, Beijing ... Wherever Qian Xuesen went, he was greeted by applause, flowers and smiling faces.
1956 1 The Institute of Mechanics of Chinese Academy of Sciences was formally established, with Qian Xuesen as the first director.
1956 Shortly after the Spring Festival, more than 200 scientists gathered at Xijiao Hotel in Beijing to study and formulate the first grand plan of new China-1956 to 1967 long-term planning outline for scientific and technological development. Qian Xuesen made a wonderful report on nuclear fusion. More than half a year later, on June 8th, 10, the Fifth Research Institute of the Ministry of National Defense, the first rocket and missile research institution in China, was formally established, with Qian Xuesen as its president.
1960165438+1October 5, China's first missile was successfully launched. On this day, it was only five years before Qian Xuesen returned to China; It is only four years before China officially launches its missile program. It took the United States nearly 10 years for this step.
Qian Xuesen devoted all his efforts and wisdom to the rocket, missile and space undertakings of the motherland. Shortly after the successful missile test, he began to think about the long-term development plan of China's missile industry and began to study the flight explosion test of the combination of atomic bomb and missile "two bombs". 1965 1 He formally suggested to the Central Committee to make a research plan for artificial satellites as soon as possible. Therefore, China's first artificial satellite project is called "65 1 project".
In 1980s, together with other scientists, he promoted the implementation of the "863" project. In the 1990s, he suggested setting up science and technology companies to promote the transformation of scientific and technological achievements, advocating the development of the fourth industry-science and technology and information industry, paying attention to the underground gasification technology of coal in the motherland, and advocating the construction of spiritual civilization. He calmly reminded a scientist that although development is comprehensive and comprehensive, it should be based on agricultural development.
Love, serve the country. This is a unique performance of a scientific old man who loves the motherland and the people. In this deep affection, Qian Xuesen's glorious life of integrating his limited life into the great construction of the motherland and the people shines brilliantly.
199 1 The Central Organization Department listed Qian Xuesen, Lei Feng, Jiao and Wang Jinxi as outstanding representatives of party member and called on the people of the whole country to learn from them. Qian Xuesen stayed up all night after learning: "I am very excited. I am now a member of the working people, and I am associated with the most advanced elements among the working people. " Keen thinking and advanced consciousness always lead the trend of the times and always stand at the forefront of science, which is Qian Xuesen's most remarkable scientific character.
From 65438 to 0948, American scientist Weiner published Cybernetics, which received a cold reception from the scientific community. However, 37-year-old Qian Xuesen keenly grasped the universal significance of this theory and applied this new theory to his own jet technology research. 1954, Qian Xuesen published the book "Engineering Cybernetics", which started a new technical science. Over the past 47 years, this book has been widely cited and referenced by scientists all over the world, and it has become a classic work with the highest citation rate in the field of automatic control.
When studying rockets in the United States, Qian Xuesen boldly proposed to use rockets to boost aircraft to achieve intercontinental flight, which coincided with the rapid development of the space shuttle. In the 1950s, when computer was just a new term, he foresaw that "many complex tasks could be simulated by computers" and strongly advocated speeding up research and development. 1985 when energy and transportation are generally regarded as the two foundations of the national economy, he suggested to the central leadership that information, communication and computers are also the foundations of the national economy and must be vigorously developed. Active thinking and creative passion have not diminished with age, but more brilliant sparks are being generated.
After system science, Qian Xuesen put forward the concepts of thinking science and human science, trying to explore new ways to realize artificial intelligence and uncover human secrets through the study of human thinking activities and human system.
From 65438 to 0990, 79-year-old Qian Xuesen published a paper entitled "The New Field of Science-Open Complex Giant System and Its Methodology", which summarized the latest development achievements of systematics and information technology, refined the new concept of open complex giant system, put forward the methodology of comprehensive integration from qualitative to quantitative, and realized the dialectical unity of reductionism and holism.
Two years later, Qian Xuesen, 8 1 year-old, further proposed to establish a seminar hall system and great wisdom integrating qualitative and quantitative aspects on the basis of systematics theory, trying to integrate the knowledge and wisdom of thousands of people through computers and the Internet.
Great creation comes from scientific methods. Dialectical materialism-this is the "secret key" for Qian Xuesen to constantly surpass his peers and always stay at the forefront of science.
Qian Xuesen's manuscript has more than 500 pages, which vividly embodies Qian Xuesen's rigorous and meticulous academic spirit. These manuscripts, selected from more than 10000 pages of scientific research notes, are exquisite and fluent in English, and the mathematical formulas are derived neatly. The chart is standard and neat, even if it is a small equal sign, it is as standard as that drawn by a ruler. In order to solve the problem of thin shell deformation, he studied more than 800 pages of manuscripts. When he reached more than 500 pages, he wrote "Not satisfied! ! ! "； After the problem was solved, he marked "Final Draft" in red ink on the envelope containing the manuscript, and then added "Science has no final draft".
Adhering to the truth and seeking truth from facts is Qian Xuesen's scientific character and his personality style. When he was young, he didn't believe in authority and had an argument with his teacher. When he became an authority, he accepted the correct opinions put forward by young college students and immediately revised his speech. He often tells people that I was a good student when I was studying in the middle school attached to Beijing Normal University, but I got more than 80 points in every exam. I was admitted to Shanghai Jiaotong University, not the first, but the third; In America, doctors' oral test scores are not the first, but the second.
From a patriotic youth to a famous scientist, from a scientific researcher to a conscious Marxist, Qian Xuesen achieved a great leap in life in his unremitting pursuit of science.
The unit wants to build a house for him, but he firmly disagrees, because "I can't live without the vast number of scientific and technological personnel"; The article praising him in newspapers and periodicals was greeted as "so far"; He didn't read the huge bonus check of HK$ 1 10,000, and donated it all to the cause of sand control in the west ... In his later years, Qian Xuesen was indifferent to honor, status and money with an open mind of Marxists.
No inscription, no preface, no jury meeting, no opening ceremony, no ribbon-cutting, no consultant, no honorary consultant, no meeting in other places, no going abroad ... Qian Xuesen refused all entertainment just to calm down, seize the day and work wholeheartedly for the scientific and technological cause and modernization of the motherland. This is his pleasure and his lifelong pursuit.
"I'm just a drop in the ocean, very small. What is truly great is the people of China, the * * * Production Party of China and the * * * Republic of China! "
This is the heartfelt words of Marxist Qian Xuesen and the sincere voice of a people's scientist.
