Lesson 28, Lighthouse Class: Thoughts after reading 1
10 16 in the afternoon, Guo Yonghuai Spirit Seminar was held in Rongcheng. The leaders of the unit where Guo Yonghuai once worked, and some students and relatives in Guo Yonghuai, * * * discussed the connotation of Guo Yonghuai spirit, so as to better carry forward the spirit of Guo Yonghuai.
Guo Yonghuai, like his name, will always be remembered. Under the explicit nuclear threat of the great powers to New China, under the economic hardship of the country's three-year natural disaster of "poverty and white", and inspired by the self-reliance spirit of New China's determination to develop atomic bombs, a cloud of grass and blue sky on the grassland witnessed the top secret history that made China people proud, and witnessed Guo Yonghuai's unrepentant pursuit of joining the nuclear cause of the motherland at the cost of his life.
I'm afraid no one can tell how much effort and sweat Guo Yonghuai has devoted to the development of China's nuclear weapons, from atomic bombs to hydrogen bombs to missile nuclear weapons. However, when Guo Yonghuai talked about this matter before his death, he often said, "As an ordinary science and technology worker in New China, especially as a native of party member, I only hope that my motherland will become stronger one day earlier and will never be bullied again. When China is strong, it will play a greater role in world affairs? "
Dare to teach the sun and the moon to change the sky for sacrifice and ambition. The spirit of "loving the motherland, selfless dedication, self-reliance, hard work, great cooperation and courage to climb" has been cast as a historical monument by Guo Yonghuai and others.
Remember it's for better motivation. The people of Sri Lanka are gone, and their spirit will last forever.
"My uncle left us unlimited spiritual wealth. We must inherit his spirit of loving the motherland, learning and science, serve the country and contribute to the people. " Guo Yonghuai niece Guo Shu 'e said.
Wang Jin is a commentator in the exhibition hall. Looking at the newly renovated exhibition hall, she felt that the burden on her shoulders was heavier. She said that as an interpreter of Guo Yonghuai's advanced deeds, she would dig up more information, study and understand Guo Yonghuai's spirit more deeply in the future, and let more people know about Guo Yonghuai and study Guo Yonghuai in an all-round way through emotional explanation.
Fearless spirit is a valuable spiritual wealth. For Rongcheng, which is accelerating the construction of an innovative city, it is urgent to learn from Guo Yonghuai's spiritual motivation.
During the war years, Rongcheng trained more than 65,438+000 generals and made great sacrifices for the national revolution. Today, it has become the frontier of reform and opening up. In the first three quarters, Rongcheng's GDP is expected to reach 84 billion yuan, up 8% year-on-year. Its main economic indicators are among the best in the city, realizing the transformation from "speed economy" to "quality economy" and the leap from "following" to "following" and "leading".
There will always be a spirit, always learning and always being new. The spirit of Guo Yonghuai inspires and encourages 670,000 Rong adults to constantly surpass themselves in the journey of solidly promoting innovation and development and striving to be at the forefront.
1958 65438+ 10, Guo Yonghuai became the editor-in-chief of Journal of Mechanics. 1957, Qian Weichang was beaten to the right. Guo Yonghuai knew Qian Weichang's academic background and still asked him to be an editorial board member. Once, a famous professor contributed to a magazine. Qian Weichang found that there were 5 1 basic mistakes in his paper and suggested that it should not be published. The professor suggested to the editorial board that "leftist professors' articles should not be censored by rightist professors", but Guo Yonghuai did not agree. He said: "We believe that Qian Weichang's opinion is correct, and it has nothing to do with left-leaning and right-leaning. "
From 65438 to 0958, the education sector launched the "educational revolution", which closely combined teaching, scientific research and production practice and achieved remarkable results, but there was also a "left" tendency in the movement. Some people think that Kudarukovsky's theorem is wrong, because throwing a cross into the air is difficult to explain. By observing that the water droplets on the lotus leaf can move freely, it is said that the boundary conditions of ns equation are wrong. At that time, the design department said that the aircraft drag could not be calculated by the boundary layer theory, so the boundary layer theory was useless. They invited Guo Yonghuai to agree with these "new discoveries". Unexpectedly, Guo Yonghuai said, "I often think that a new discovery should have the following tasks to overthrow something. First of all, we should think carefully. The question you mentioned was not well thought out. We only see the superficial phenomenon and draw conclusions. Second, we should have real courage and dare to do research. You are brave in lotus leaves, but you are not scientific. Third, you should have perseverance, you can ask questions and study problems, and you should have endless perseverance. You are not like this, you rely on temporary enthusiasm. "
Lessons learned from lighthouses Lesson 28 II
Guo Yonghuai, 1909, was born in a peasant family in Rongcheng county, Shandong province. He has been herding cattle and collecting firewood since he was a child. Because his family was poor, he went to school at the age of 9. He studied at Mingde Primary School in Shidao Town and High School affiliated to Qingdao University. His grades have always been top-notch, and he has been favored and rewarded by the school. After graduating from junior high school, he was admitted to the science class of Nankai University. It was very rare for a farmer's child to embark on such a road at that time, so he especially cherished the opportunity of learning and was admitted to the Physics Department of Peking University with 1933. After graduation, he was hired as a teaching assistant and graduate student by Rao Yutai, a famous optical expert.
1937, after the guns of Lugou Bridge sounded, Guo Yonghuai moved south with the teachers and students of Peking University, and went through hardships to Kunming to study aviation engineering at the newly-built National Southwest Associated University. 1939 was admitted to the Chinese and British "boxer indemnity" students. Before boarding the ship in Shanghai, he found that the passport he received was actually issued by the Japanese government. He was furious and resolutely gave up the opportunity. Eight months later, Guo Yonghuai received a notice to study in Canada and entered the University of Toronto. It took him only half a year to get a master's degree in mathematics, and then he chose an important theoretical problem of aerodynamics as the topic of his doctoral thesis. Because his tutor thought it was difficult to solve this problem, he went to California Institute of Technology to consult Von Carmen, an aviation master, and made friends with Qian Xuesen and Qian Weichang who studied there. From 65438 to 0945, after receiving his doctorate, Guo Yonghuai went to teach at Cornell University in the United States and soon became an associate professor and professor.
1956, Guo Yonghuai broke through the obstruction of the American government and returned to the motherland with his family. Recommended by Qian Xuesen, who returned to China early, he served as the deputy director of the Institute of Mechanics, Chinese Academy of Sciences. During the 12 years after returning to China, Guo Yonghuai has been pursuing progress and joined the China * * * Production Party, taking the remuneration as party dues and giving the electric computers and exhaust fans brought back from abroad to the public for use.
1960, after the central government decided to develop nuclear weapons by itself, 105 scientists formed a special research team. Guo Yonghuai served as the vice president of the Ninth Hospital, in charge of the mechanical department, and was responsible for the design guidance of weaponization. From 65438 to 0963, he and his research team moved to a new base in Qinghai. They often lived in harsh natural conditions and solved many important dynamic problems. He has been dubbed as one of the "Three Bodhisattvas" in the field of nuclear research (the other two are heads of theoretical and experimental departments).
In June of 20th century/KLOC-0 and May of the following year, the first and second bullets in China exploded successively, and Premier Zhou and Deng Xiansheng specially hosted a banquet in honor of scientists such as Guo Yonghuai. 1965, Guo Yonghuai participated in the development of hydrogen bombs and the design of artificial satellites. At the same time, in order to complete the foreign aid task, he also served as the chief designer of developing individual shoulder-mounted air defense missiles, and miraculously made this ultra-low altitude surface-to-air missile in less than half a year.
196865438+On February 5th, Guo Yonghuai went to Beijing to report from Qinghai Experimental Base. The plane crashed when it landed, and he died at the age of 59. On February 25th of the same year, 12, the Ministry of Internal Affairs ratified him as a revolutionary martyr.
Lesson 28, Lighthouse Classroom: What do you think of it?
Guo Yonghuai (65438+April 4th, 0909—196865438+February 5th), male, born in Rongren, Shandong Province, was born in 1989, party member. Famous mechanic, applied mathematician, aerodynamicist, academician of China Academy of Sciences, one of the founders of modern mechanics. He has been engaged in aviation engineering research for a long time, found the upper critical Mach number, developed the deformed coordinate method in singular perturbation theory, assumed the business leadership of national defense scientific research, and made important contributions to the development of missiles, nuclear bombs and satellites. From 65438 to 0999, Mr. Guo Yonghuai was awarded the Medal of Honor with two bombs and one star, and he was the only scientist in this group who was awarded the title of "martyr".
A person's life consists of too many 10 seconds. Some people may yawn lazily, and 10 seconds will suddenly pass. Some people, however, complete an earth-shattering action in 10 seconds, showing indomitable posture, thus achieving eternal life.
He is too tired, but he has too much work to do. 196865438+On February 4th, he made another important discovery. Time is more important than anything. He decided to report the good news to the leader immediately and flew to Beijing from Qinghai base that night. A colleague advised him, "It's not safe at night, so go tomorrow." He smiled and said, "Good evening. I'll go as soon as I sleep. " Tired as he is, he doesn't want to delay a minute. He wants to take this trip as a trip.
He is Guo Yonghuai, vice president of China Nuclear Weapons Research Institute. When he arrived in Lanzhou by bus, he did not forget to take the time to listen to the report of the research team during his transit in Lanzhou.
In the afternoon 10, he boarded the plane. "Wake me up if something happens." After boarding the plane, Guo Yonghuai told the guard Mou Fangdong, and then fell asleep. He slept soundly, because in his opinion, there are many things to be done for such a night and a day.
That night, the weather was fine and the flight was smooth. The morning light came through the porthole, and the plane was approaching Beijing. The guard gently woke him up. Having not slept for such a long time, Guo Yonghuai feels refreshed.
Switch shots here:196865438+At about 6 am on February 5, earth-shattering thunder sounded at the Capital Airport, and then a huge fireball and thick black smoke soared into the sky! A small plane plunged into the corn field near the Capital Airport!
Aircraft wreckage was scattered all over the floor, 13 people were killed, and charred bodies were scattered all over the floor. The rescue soldiers found two people hugging each other in the charred body.
Although they can't see their faces clearly, they embrace together, such as coal formed in hundreds of millions of years, which contains great energy. People seem to see the brilliant light shining on the world! It is so hard and rich in connotation that it flies over the vast and unburned meteorites in the sky! Yes, it was Guo Yonghuai and his guard MouFangDong who hugged each other tightly.
It turned out that the plane flew over the Capital Airport and began to land slowly. The landing gear fell, 2000 meters, 1000 meters, 500 meters ... However, when the plane descended to a height of about 400 meters, it suddenly lost its balance and began to fall vertically. It took less than 10 seconds for the plane to fall to the ground from a height of 400 meters. At that moment, Guo Yonghuai suddenly stood up and hugged the guard standing beside him.
Why did Guo Yonghuai hug the guard? When the soldiers tried to separate the two bodies, people were surprised to find a leather briefcase between their chests. Although a little burnt, it is still intact under the protection of the body embraced by the two. After opening the briefcase, a thermonuclear missile test data file is presented to people intact!
People can't understand: What can 10 second do? But Guo Yonghuai kept this document. There may be only one explanation, that is, Guo Yonghuai kept his briefcase as close to his heart as life, and never touched it when he slept. His heart is a heart loyal to the people. Only great loyalty can produce great wisdom, and great wisdom can produce great courage!
Yes, Guo Yonghuai has always been loyal to the people. The research base is located in the plateau area at an altitude of more than 3800 meters. The climate is changeable, and the lowest temperature in winter is MINUS 40 degrees Celsius. Not to mention birds, the proving ground is desolate and barren. Coupled with the lack of oxygen and materials at that time, many researchers were malnourished and swollen at high altitudes. As a leader, Guo Yonghuai is well aware of the great responsibility on his shoulders and often forgets to eat and sleep. Less than 50 years old, he is thin and white-haired. He is so tired that he never has time to work for the people in order to save time.
Guo Yonghuai was 59 years old when the accident happened. The news of his unfortunate death reached the State Council for the first time, and Premier Zhou Enlai burst into tears! He is like a brother, and the eternal "big brother" Qian Xuesen couldn't help crying when he heard the news. He had nightmares for days!
Because of Guo Yonghuai's righteousness and courage, he kept the document intact. After 22 days of sacrifice, China's first thermonuclear missile test was successful; Two years later, on April 24th, 1970, China's first artificial satellite was successfully launched.
If you can't land safely, you will get eternal life in 10 seconds! What burns is the body, and what burns is the spirit. The spirit of Guo Yonghuai will never fall, and it has become the mainstay of the world, standing in people's hearts forever!
Lesson 28, Lighthouse Classroom: What do you think of it?
1965 Guo Yonghuai once said: "As a China person, especially a member of the revolutionary ranks, I sincerely hope that a big country like ours will realize the four modernizations and build a prosperous and powerful socialist country as soon as possible, so as to inspire the revolutionary people all over the world." In order to achieve this grand goal, he gave everything.
He shoulders the heavy responsibility of developing modern mechanics and cutting-edge science in China, and Guo Yonghuai always has a sense of urgency. Therefore, he always works tirelessly. His work schedule is always full, and he has to personally ask about the business problems of the Institute of Mechanics and related units. A large number of documents and scientific research reports need him to deal with. He never takes a lunch break and often works late into the night. He doesn't have a holiday. He either goes to work in the office as usual, or stays at home, burying his head in a book case and reading a lot. Because of his endless pursuit of new knowledge, he is always familiar with the new trends of modern mechanics and cutting-edge technology development in the world, and can always give detailed guidance to various complex topics. Abroad, he has some hobbies: he likes collecting stamps and has a high taste in music. After returning to China, due to his busy work, he seldom had time to ask about his stamp collection or enjoy beautiful music.
He is diligent himself and expects others to be diligent. He often warns young people with his own personal experience: "Genius is useless, the key is to study hard. Learning is endless, and only hard work can occupy the fortress of science. " He also used the story of Newton and chicken bones to educate everyone and asked everyone to study and work with a kind of "stupid energy". The comrades around him were deeply infected by words and deeds, and his spirit of serving the public wholeheartedly and forgetting myself remained in people's memory.
On academic issues, Guo Yonghuai is famous for his preciseness. He never allows ambiguity, ambiguity, haste or making up a few words casually. There are not many scientific papers published in his life, but each one has certain weight and value; Before publication, he always checked it again and again, choosing words carefully and very carefully. After returning to China, in order to meet the needs of teaching, he systematically introduced the classic works of fluid mechanics abroad. He personally translated the Introduction to Fluid Mechanics (version 1952) by Pelant, which put high demands on his faithfulness and elegance. In order to make the translation accurate and smooth, he repeatedly compared the original German version with the English version and discussed it with relevant comrades for dozens of times. Notes were added to the omissions in the original book. In this way, it lasted eight years before and after, and it was not officially published until after his sacrifice. After the publication of this high-level translation, it was printed twice in a row, which sold well at home and abroad and was well received by all parties. In the process of guiding scientific research, he requires that the work plan must have indicators, progress and feasibility. If it is empty or exaggerated, it will be returned for re-formulation; For academic reports, he requires clear arguments and sufficient arguments, and gives positive or negative conclusions under certain conditions; In academic discussions, he never misses a slight mistake. On one occasion, a young comrade reported that he needed to draw a velocity distribution curve under turbulent conditions, so he drew one casually. Guo Yonghuai immediately pointed out that it could not reflect the characteristics of turbulence and asked the young comrade to correct it.
He was the editor-in-chief of Journal of Mechanics before his death, and he kept a strict check on manuscripts, regardless of personal relationship or the size of contributors. On one occasion, there was a disagreement over an authoritative manuscript in the field of mechanics. The reviewer gave a positive opinion, but a young man made a sharp criticism. Therefore, Guo Yonghuai specially organized an academic seminar to listen to opinions from all sides. As a result, it was found that the basic equation was wrong, and Guo Yonghuai firmly supported this "little guy" who had never met before. 1963, the editorial department of Journal of Mechanics received a critical letter about a paper written by two young people working under the guidance of Guo Yonghuai. Guo Yonghuai read the letter carefully and asked the two authors to seriously consider other people's opinions and give an answer. He said: "I advocate publishing papers for academic exchanges in order to arouse discussion. Criticism from others can only give us a deeper understanding of the problem. "
Guo Yonghuai is a man of seeking truth from facts. He never does what others say. Once he finds out that the truth is not on his side, he can correct his mistakes in time. Guo Yonghuai is strict and meticulous with people, but he is approachable. Sometimes, even if his opinion is correct, it is difficult to achieve objectively, and he will take it back in time. Once, he asked a laboratory to test the turbulence in the wind tunnel. When he found that the signal-to-noise ratio of domestic electronic instruments was relatively low, he stopped insisting on his own views. He once said to young people more than once: "I give your advice for your reference only, not necessarily according to my method, everything must be tested by practice." It is precisely because he is seeking truth from facts, sticking to the truth, being open-minded and not oppressing others by force that his prestige is higher in people's minds.
He is a hero of our Chinese nation, and there is only a glimmer of light with his existence!
