The story of patriotic sons and daughters serving the motherland
Hua Luogeng is a world-class mathematician who is self-taught. He only had a junior high school diploma. Because a paper was published in Science magazine, it was appreciated by mathematician Xiong Qinglai. From then on, Hua Luogeng went north to tsinghua campus and began his mathematics career. In 1936, recommended by Professor Xiong Qinglai, Hua Luogeng went to England to study in Cambridge. Hardy, a famous mathematician in the 2th century, had long heard that Hua Luogeng was brilliant. He said, "You can get a doctorate in two years." But Hua Luogeng said, "I don't want to get a doctorate. I just want to be a visitor." "I came to Cambridge to study, not for a degree." In the past two years, he concentrated on the study of the theory of heap base primes, and published 18 papers on the Waring problem, the altruistic problem and the odd Goldbach problem, and obtained the famous Fahrenheit Theorem, which showed the outstanding wisdom and ability of China mathematicians to the whole world. In 1946, Hua Luogeng was invited to give lectures in the United States, and was hired as a tenured professor by the University of Illinois with a high salary. His family also settled in the United States with a house and a car, and their life was very comfortable. At that time, many people thought that Hua Luogeng would never come back. The birth of the new China touched the heart of Hua Luogeng, who loves the motherland. In 195, he resolutely gave up his comfortable life in the United States and returned to the motherland. Moreover, he wrote an open letter to China students studying in the United States, urging them to return to China to participate in socialist construction. In his letter, he frankly revealed a pure heart of loving China: "Friends! Although Liangyuan is good, it is not a long-lived hometown. Go back to Xi ... For the sake of the nation, we should go back ... "Although mathematics has no national boundaries, mathematicians have their own motherland. Hua Luogeng returned from overseas and was warmly welcomed by the Party and the people. He returned to tsinghua campus and was appointed as the head of the Department of Mathematics, and was soon appointed as the director of the Institute of Mathematics of China Academy of Sciences. From then on, the real golden age of his mathematical research began. He not only made outstanding achievements that attracted the world's attention, but also enthusiastically cared for and trained a large number of mathematical talents. He devoted a lot of efforts to the research, experiment and popularization of applied mathematics. According to incomplete statistics, Hua Luogeng has published 152 important mathematical papers, 9 mathematical works and 11 mathematical popular science works in decades. He was also elected as a foreign academician of the Academy of Sciences and an academician of third world scientists. From junior high school graduation to people's mathematician, Hua Luogeng has gone through a tortuous and brilliant life path and won great honor for his motherland.
China No.1 aircraft designer, manufacturer and aviator Feng Ru Feng Ru (1884-1912), formerly known as Feng Jiuru, was born in a peasant family in Xingpu Village, Niujiang, Enping on January 12, 1884 (December 15 of the ninth year of Guangxu reign in Qing Dynasty). When he was a child, he studied in a rural private school for years and stayed at home to farm after dropping out of school.
in p>1898, when Feng Ru was 16 years old, his parents married him, and his wife was Liang Sanju, Zhulin Village, Dashagangping Township, Enping.
Due to the difficulties of life, Feng Ru left his parents and his wife shortly after their marriage in 1899, and went across the ocean to make a living in San Francisco with Wu Yinglan, the younger brother of his cousin and aunt.
Talented and imaginative
When studying in a private school in the village, Feng Ru was very diligent, and his academic performance was among the best among his classmates. When he writes, he often reveals many fantasies and puts forward many thought-provoking questions. For example, why do birds fly in the sky, why can they soar freely in the sky, why can they fly quickly and slowly, and sometimes even stay in the air, and so on. The teacher saw his compositions and called him a "visionary child".
Feng Ru often creates some novel toys. He made a kite like a big bird, with two small wooden barrels hanging from its wings. When the kite slowly rose into the sky by the wind, the small wooden barrels became small wind bags, which played a role in balancing flight, and the adults and children in the village were amazed. He also built a boat out of a matchbox and put it in a fish pond to let the wind blow and float around. People praised him for his idea.
addicted to aircraft manufacturing
in p>193, the news that the Wright brothers in the United States succeeded in creating an airplane caused a sensation in the world. Feng Ru, 2, was attracted by this invention. Being overseas, he felt bullied by foreign powers. He thought that the reason why the powers dared to bully us was to rely on those strong ships and guns. Aircraft plays a great role in the military, so he is determined to devote himself to the cause of aircraft manufacturing, so as to serve the motherland in developing aviation in the future and make the motherland strong. From then on, when he was free, he went to libraries, bookstores and friends' homes to collect and consult books and materials about aircraft principles and began to develop aircraft models.
Although young Feng Ru has the ambition to start a business, he has no capital to start a business. In order to solve the financial problem, he came to San Francisco from new york in 196, and mobilized overseas Chinese to invest and set up a machine factory to make airplanes. Feng Ru's sincere heart has inspired overseas Chinese youths Zhu Zhuquan, Zhu Zhaohuai (Taishan native) and Situ Biru (Kaiping native) to start a business for their country. They are not only willing to pay, but also willing to be apprentices to develop airplanes with Feng Ru. With the support of overseas Chinese, Feng Ru finally set up an aircraft development factory. In the factory, the apprentices worked around the clock, burying their heads in the pile of design drawings. When the drawings came out, they made models. With the efforts of the apprentices, the internal combustion engine of the plane was first made.
in may p>198, the first airplane was made. They were very excited, and Feng Ru was as happy as if his child was born. He seriously thought and planned the test flight, and others also made preparations seriously. Then, they transported the plane to Maiyuan in Dalinko for a test flight. But the test flight of the plane failed.
in September p>198, after the second plane was built, they made a test flight-improved it-and then made a test flight, but it failed five times in a row. The last time, the plane flew a few feet high and fell down, and the plane was destroyed. Fortunately, it didn't hurt anyone, but it showed Feng Ru the hope of success. Many funders, seeing repeated failures, have lost confidence and are unwilling to subsidize any more. When the situation was extremely difficult, Feng Ru received letters from his parents one after another, urging him to return home. "If the plane can't be built, I will never return to China." Feng Ru made an oath. Feng Ru resolutely wrote back to his parents and said, "I hope my parents will forgive me, and I can return to China after the plane is made." He led his disciples to scrimp and save, continue to raise funds and improve aircraft facilities.
but how can the plane be improved to meet the requirements? One day, he happened to see several eagles hovering in the air, rising and falling freely. He pondered for a long time and suddenly realized that he immediately borrowed a white pigeon from his neighbor and carefully measured the ratio of the pigeon's body to the length of its wings with a ruler, from which he was inspired. So he happily said to his disciples, "There is hope of success when you get off the plane!"
Achievements made a sensation overseas
In the autumn of p>199, an airplane that was manipulated, lifted and landed to meet the design requirements was successfully manufactured. On September 16th and 22nd, Feng Ru made two successful short-distance flights in Piedmont with a newly improved plane. On 23rd, the San Francisco Observer reported it in the first edition with a big headline, calling Feng Ru a "genius" and exclaiming, "In aviation, whites have fallen behind Chinese?" At that time, Dr. Sun Yat-sen was in the United States, and he also watched it in person. He praised Feng Ru's spirit of patriotism and striving for strength, and said happily: "There are many people who love the country and save the country!" Sun Yat-sen's words gave Feng Ru great encouragement. Those overseas Chinese who had previously sponsored Feng Ru to build airplanes have regained their confidence. With the support of overseas Chinese, a "Guangdong Manufacturing Machine Company" was formally established, with Feng Ru as the chief mechanic.
Sure enough, Feng Ru lived up to the expectations of Dr. Sun Yat-sen and overseas Chinese. In October 191, Americans held an "International Air Flight Competition" in San Francisco. Feng Ru took part in the competition in a plane designed and manufactured by himself. Feng Ru's plane won the first place in the competition with an altitude of 211m, a speed of 15km/h and a flying speed of 32km, and was awarded a certificate of excellence by the International Flying Association. At that time, newspapers all over the country reported the miracle of Feng Ru, and Feng Ru's name also caused a sensation overseas, which made Chinese people proud.
At that time, Americans wanted to recruit him with heavy money and keep him in the United States forever. A British aviation boss also wanted to use gold to buy his aircraft design technical data, but Feng Ru refused. Later, Americans tried to deny Feng Ru's patent right to design and manufacture airplanes. Feng Ru refuted the argument and scoffed at these Americans. He just wants to live up to expectations for China people and serve the motherland.
technology dedicated to the motherland
In February p>1911, Feng Ru returned to the motherland with all the factory personnel, aircraft equipment and built aircraft, including Zhu Zhuquan, Zhu Zhaohuai and Situ Biru. They plan to hold an air show in Guangzhou to publicize the significance of the aircraft manufacturing industry to the people of the motherland. However, the fatuous and corrupt Qing government accused him of having ties with revolutionaries and forbade him to perform.
although the patriotic enthusiasm of Feng Ru and the shareholders of Guangdong Manufacturing Machinery Company to revitalize China's aviation industry has been hit, they still aim at "strengthening the country and strengthening their rights" and listed Guangdong Manufacturing Machinery Company, which moved back from the United States, in Guangzhou to manufacture machines and airplanes. The company was renamed as "Guangdong Aircraft Company", and Feng Ru was one of the founders and served as the chief mechanic.
Feng Ru, who swore that he would never return to China until the plane was built, and promised his parents that he would return to China once the plane was built, returned to his hometown around May, 1912 to visit his parents and wife who had been separated for more than ten years. Feng Ru was very happy with the family reunion. He took his family and ran to the "Yanfang" photo studio in Encheng to take photos as a souvenir.
unfortunate accident and sacrifice
When the Revolution of 1911 broke out, Feng Ru resolutely joined the revolution. With the fall of the Qing Dynasty and the founding of the Republic of China, Feng Ru had new hope.
in p>1912, Feng Ru applied to the then army commander for an airplane flight performance, which was approved. On August 25th of the same year, at 11: a.m., the sun was shining over Guangzhou, and thousands of people in the suburbs of Shougouling and Yantang were eagerly watching.
Feng Ru flew the plane excitedly, soaring freely. The ground was filled with cheers and applause.
At this time, Feng Ruzheng made the plane fly higher, only to see the fuselage vibrate sharply, with its head high and tail low, losing its balance and tilting. At that time, there was no seat belt and landing equipment to control the body, which caused Feng Ru to be thrown out of the frame and fall to the ground, seriously injured. He woke up in the hospital and said to his disciples, "After I die, don't lose heart because of this accident." Feng Ru died at the age of 28 because of ineffective treatment.
after the inspection, some parts of the plane rusted because it was idle for one year, so that the controller failed and an accident occurred.
After Feng Ru's martyrdom, on September 24th, the military government held a memorial meeting and offered pensions to his family. On November 16, the interim president issued an order, "giving a shirt for the death of a major general."
Feng Ru's body was buried in the air force cemetery, and now it is moved to the left of the 72nd tomb of Huanghuagang, and a monument has been built for future generations to pay tribute to.
