1, the famous mathematician Hua Luogeng was recruited to the United States in 1946 to lecture, very much valued by the academic community. At that time, the University of Illinois in the United States, with an annual salary of 10,000 U.S. dollars, and he entered into a tenured professorship appointment. Hua Luogeng's life was immediately comfortable, not only with a small house, the university side also specially equipped him with four assistants and a typist. After the founding of New China, some people always think that Hua Luogeng in the United States has been successful, living a good life, is not going to come back. However, material, money and status did not hold his patriotic heart. 1950 February, Hua Luogeng resolutely gave up in the United States "broad professor" treatment, broke through the blockade to return to the motherland. Passing through Hong Kong, he wrote an "open letter to students in the United States", expressing his devotion to the motherland. He appealed with enthusiasm, "For the sake of the country and the nation, we should go back!" "Though Jincheng is happy, it is better to go back to our hometown; though Liangyuan is good, it is not a place to stay for a long time."
Major Achievements: Founder and pioneer of analytic number theory in China
Quote: Work until the end of your life
2. The famous geologist Li Siguang studied hard for six years at the University of Birmingham in England in his early years, and obtained a master's degree in geology. His teacher, Prof. Baldon, advised him to stay and further his studies and return to China after obtaining his doctorate. Li Siguang declined his teacher's kind offer and replied, "No, I want to contribute what I have learned to my motherland as soon as possible." He returned to China in 1920 and worked there until the outbreak of the Anti-Japanese War in 1937. Then, for a time, he went abroad, where he still persisted in his research work in geology. By 1950, he gave up the favorable conditions abroad, in the new China is waiting for the emergence of the time, resolutely from the United Kingdom detour back to China, as the new China's Minister of Geology for China's petroleum industry to set up outstanding merits.
Major achievements: the creation of the theory of geomechanics, for China to get rid of the "oil-poor" hat, for China's success in the development of atomic and hydrogen bombs.
3. Deng Jiaxian, the founder of China's "two bombs", received his doctoral degree in the United States, and the United States was going to give him good conditions and generous treatment, hoping that he could work in the United States for a long time. However, Deng did not waver in his determination to work in his motherland because of his high official position and salary, and he returned to his motherland in 1950 with the ambition to serve his country, and made outstanding contributions to the successful development of the "two bombs". From the atomic bomb, hydrogen bomb principle breakthroughs and test success and its weaponization, to the new nuclear weapons major principle breakthroughs and development and testing, have made significant contributions; as a major participant in the results were awarded the first prize of the National Natural Science Prize and the National Award for Scientific and Technological Progress Grand Prize; Deng Jiaxian is known as "the father of the Chinese atomic bomb".
4. Zhou Peiyuan, a famous contemporary Chinese physicist, was invited to participate in the research work of the U.S. Wartime Scientific Research and Development Administration in 1945. Along with the end of World War II, the U.S. Department of the Navy set up the Naval Military Industrial Experiment Station and hoped that Zhou Peiyuan would work at the station with favorable treatment. However, the Department of the Navy is a U.S. government department, in the Department of the Navy unit will become a civil servant of the U.S. government, foreign personnel must join the U.S. citizenship in order to participate. Zhou Peiyuan immediately put forward three conditions to the U.S. side: first, not to join the U.S. citizenship; secondly, only to undertake temporary research tasks; thirdly, you can leave at any time. 1947 February, Zhou Peiyuan resolutely left the United States to return to his motherland's embrace with his wife and children. Academic Achievements: He laid the foundation of the turbulence model theory for the study of two important aspects of the fundamental theories of physics, i.e., the gravitational theory of Einstein's general theory of relativity and the turbulence theory of fluid dynamics; he also researched and preliminarily proved the important thesis of "coordinate correlation" in the gravitational theory of the general theory of relativity.
5, the founder of China's atomic energy science, Qian Sanqiang, in 1937 to study in France to study atomic theory, by the small Curie couple that he is the most outstanding scientific researchers. 1948, Qian Sanqiang and his wife, He Zehui proposed to return to the United States, the tutor and colleagues have repeatedly persuaded, retained. The ambassador of the Kuomintang government in France threatened viciously, "It would be strange to see him make it to the shores of the mainland!" The meaning was clear. If Qian Sanqiang insisted on returning to the motherland, the Kuomintang agents would poison him halfway. Qian Sanqiang disregard for personal safety, put life and death at risk, and his wife holding just half a year old daughter, decisive and resourceful to return to the embrace of the motherland, for the development of China's atomic energy has made significant contributions to the cause of China's nuclear energy, known as China's "father of the nuclear bomb".
6. Qian Xuesen, known as the "father of modern Chinese rocketry", is a famous aerospace engineering and aerodynamics expert. He studied in the United States in his early years, under the guidance of Prof. Von Karmen. In 1947, at the age of 36, Qian was hired as a tenured professor at the Massachusetts Institute of Technology. When the good news of the founding of New China reached Qian Xuesen, he thought: "I am a Chinese, I can give up everything here, but I can't give up my motherland. I should return to my motherland at an early date and contribute my full strength to building a new China." In order to serve the newborn but backward motherland, Qian Xuesen formally applied to his authorities in the United States to return to China since 1950. However, the U.S. authorities obstructed and persecuted him by confiscating his materials and books, framing him as a "spy", interrogating and imprisoning him, and detaining him on an isolated island for only half a month, causing him to lose 14 kilograms in weight. At that time, the U.S. authorities claimed that as long as Qian Xuesen gave up the idea of returning to China, they would provide him with laboratories and instruments as usual. However, Qian Xuesen would rather die than go back to China and never gave in. Through five years of arduous struggle, under the cordial care of Premier Zhou Enlai, Qian Xuesen embarked on September 17, 1955, on his way back to China. After returning to China, Qian Xuesen for the new China's aerospace industry jumped into the forefront of the world and set up a monumental feat.
7. Su Buqing, a famous mathematician, studied in Japan in his early years and received his doctorate in 1931. Many famous universities in Japan hired him with high salaries, but he thought of studying abroad in order to master science and serve the motherland, so he resigned one by one and returned to China. After returning to China, he taught at Zhejiang University, but he could not receive his salary for four months in a row, so poor that it was difficult to even eat, while the Imperial University of Japan also promised to keep his salary for half a year. Poverty is hard to change the patriotic heart, Su Buqing no intention to go back to Japan. After the outbreak of the War of Resistance against Japan, the Imperial University of Japan sent a telegram, asking him to teach. For the sake of national righteousness, he flatly refused, "I want to stay in my own country. No matter how poor my motherland is, I will fight for her and serve her!"
8, Chinese nuclear physicist Wang Ganchang early years in order to support the anti-Japanese war, the Japanese invaders out as soon as possible, he will be his family's savings of silver, jewelry, all dedicated to the motherland. 1961, when the country appeared a serious natural disaster, the money is very short, the Soviet Union in Wang Ganchang will be their own frugal frugal savings of 140,000 rubles (about 20,000 yuan 30,000 yuan) to the Chinese Embassy in the Soviet Union to pass on the Chinese Embassy, and the Chinese Embassy in the Soviet Union.
Major Achievements: He is the main founder and pioneer of China's experimental atomic nuclear physics, cosmic ray and elementary particle physics, and enjoys a high reputation in the international arena. He is known as the "Father of Chinese Nuclear Weapons" and "Father of Chinese Atomic Bomb". In 70 years of scientific research career, he struggled to climb, made a number of scientific achievements that made the world attention. 1998 December 10, 21:48, Wang Ganchang died in Beijing at the age of 91 due to illness.
