The story of patriotic sons and daughters serving the motherland
China's great wish to serve the motherland

Hua is a self-taught world-class mathematician. He only has a junior high school diploma. Because a paper was published in Science magazine, it was appreciated by mathematician Xiong Qinglai. From then on, North China went to Tsinghua and began his mathematics career. 65438-0936, recommended by Professor Xiong Qinglai, Hua went to Cambridge University in England to study. Hardy, a famous mathematician in the 20th century, has long heard that China is brilliant. He said, "You can get a doctorate in two years." But Hua said, "I don't want to get a doctorate." I just want to be a tourist. " "I came to Cambridge to study, not to get a degree." In the past two years, he has devoted himself to studying the theory of heap prime numbers, published 18 papers on the problems of Waring, altruism and Chigodbach, and obtained the famous "Fahrenheit Theorem", which showed the outstanding wisdom and ability of China mathematicians to the whole world. From 65438 to 0946, Hua was invited to give lectures in the United States and was hired as a tenured professor by the University of Illinois. 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 would never come back. The birth of the new China touched China's love for the motherland. 1950, he resolutely gave up his comfortable life in America and returned to his motherland. He also 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 confessed his love for China: "Friends! Although Liangyuan is good, it is not the hometown of longevity. 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 returned from overseas and was warmly welcomed by the party and people. He returned to Tsinghua campus, 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 has not only made remarkable achievements that have attracted worldwide 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 * * * has published important mathematical papers 152, 9 mathematical works and1/mathematical popular science works for 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 has gone through a tortuous and brilliant life path and won great honor for his motherland.

Feng Ru, the first aircraft designer, manufacturer and pilot in China.

Feng Ru (1884- 19 12), formerly known as Feng Jiuru, was born in a farmer's family in Xingpu Village, Niujiang, Enping, with the word Ding San, 1884, 12 (September 15th, Guangxu, Qing Dynasty).

1898, when Feng Ru 16 years old, his parents married him, and his wife was Liang Sanju, Zhu Lin Village, Dashagangping Township, Enping.

Due to the difficulties of life, Feng Ru left his parents and wife shortly after 1899 got married, and went across the ocean to make a living in San Francisco with his cousin menstruation's younger brother Wu Yinglan.

Brilliant and imaginative.

When studying in a private school in the village, Feng Ru was very diligent and her academic performance was among the best among her classmates. When he writes, he often reveals many fantasies and raises many thought-provoking questions. For example, why do birds fly in the sky, why can they fly freely in the sky, why can they fly fast and slow, and sometimes even stay in the air, and so on. The teacher read his composition and called him a "visionary child".

Feng Ru often creates some novel toys. He made a kite like a big bird, with two small barrels hanging on its wings. When the kite slowly rose into the sky by the wind, the small barrel became a small wind bag, 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 everywhere. People praised his idea.

Minimum aircraft manufacturing company

1903, the news that the Wright brothers in the United States succeeded in building an airplane caused a sensation in the world. Feng Ru, 20, was attracted by this invention. Being overseas, he felt threatened by foreign forces. 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, serve the motherland for the future development of aviation and make the motherland strong. From then on, whenever he was free, he went to libraries, bookstores and friends' homes to collect and consult books and materials about the principle of aircraft and began to develop aircraft models.

Although young Feng Ru has entrepreneurial ambition, he has no entrepreneurial capital. In order to solve the problem of funds, he came to San Francisco from new york in 1906, mobilized overseas Chinese to invest and set up a machine factory to manufacture airplanes. Feng Ru's sincere heart inspired overseas Chinese youths Zhu Zhuquan, Zhu Zhaohuai (Taishan people) and Situ Biru (Kaiping people) to start businesses for their country. They are not only willing to pay, but also willing to work as apprentices with Feng Ru to develop airplanes. With the support of overseas Chinese, Feng Ru finally set up an aircraft development factory. In the factory, apprentices work day and night, immersed in that pile of design drawings. After the drawings came out, they made a model. Thanks to the efforts of the disciples, the internal combustion engine of the plane was first made.

1908 in may, the first aircraft was manufactured. They were so excited that Feng Ru was as happy as if his child had been born. He carefully thought and planned the test flight, and others also made serious preparations. Then, they transported the plane to the wheat field in Linke for a test flight. But the test flight of the plane failed.

1September, 908, after the second plane was built, they tested it-improved it-and then tested it again, but failed five times in a row. The last time, the plane flew a few feet and fell down, and the plane was destroyed. Fortunately, no one was hurt, but Feng Ru saw the hope of success. Many funders see failures again and again, lose confidence and don't want to fund 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 took an oath. Feng Ru resolutely wrote back to his parents and said, "I hope my parents will forgive me. I can go back to China when the plane is built." He led his disciples to scrimp and save, continue to raise funds and improve aircraft facilities.

But how can the aircraft 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!" "

A sensational achievement overseas.

/kloc-in the autumn of 0/909, a plane with control, lifting and landing meeting the design requirements was successfully manufactured. On September 16 and September 22, Feng Ru made two successful short flights in Piedmont with a newly improved aircraft. The San Francisco Observer reported in the first page on the 23rd that Feng Ru was a "genius" and exclaimed: "In the aviation field, white people have fallen behind China people?" At that time, Dr. Sun Yat-sen was in the United States, and he also watched it himself. He praised Feng Ru's spirit of patriotism and self-improvement and said happily: "There are many people who love their country and save the country!" Sun Yat-sen's words gave Feng Ru great encouragement. Those overseas Chinese who once 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. 191kloc-0/0 in June, 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 aircraft won the first place in the competition with an altitude of 265,438+065,438+0 m, a speed of 65,438+005 km/h and a flying speed of 32 km, and was awarded a certificate of excellence by the International Flying Association. At that time, newspapers all over the country were reporting 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 heavily and let him stay in the United States forever; A British Airways boss also wanted to buy his technical data of aircraft design with gold, but Feng Ru refused. Later, Americans tried to deny Feng Ru's patent right to design and manufacture airplanes. Feng Ru refutes the argument and scoffs at these Americans. He just wants to live up to the expectations of the people of China and serve the motherland.

Technology is dedicated to the motherland

19 1 1 In February, Feng Ru returned to the motherland with Zhu Zhuquan, Zhu Zhaohuai, Situ Biru and other factory personnel, aircraft equipment and built aircraft. They plan to hold an air show in Guangzhou to publicize the importance of aircraft manufacturing to the people of the motherland. However, the fatuous and corrupt Qing government accused him of having ties with revolutionaries and banned him from performing.

Although the patriotic enthusiasm of Feng Ru and the shareholders of "Guangdong Machine Manufacturing Company" to revitalize China's aviation industry has been hit, they still aim at "strengthening the country" and listed the "Guangdong Machine Manufacturing Company" moved 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 vowed that "I will never return to China until the plane can be built" and promised his parents that "the plane can be built", returned to his hometown around May 19 12 to visit his parents and wife who had been away for more than ten years. Feng Ru is very happy about family reunion. He took his family to the "Yanfang" photo studio in Encheng to take photos as a souvenir.

Tragically destroyed and sacrificed.

When the Revolution of 1911 broke out, Feng Ru resolutely joined the revolution. With the collapse of the Qing Dynasty and the establishment of the Republic of China, Feng Ru had new hope.

19 12, Feng Ru applied to the then army commander for an airplane flight show, which was approved. On the morning of August 25th of the same year 1 1, the sun was shining over Guangzhou, and thousands of people were watching.

Feng Ru flew the plane excitedly and soared freely. The scene was filled with cheers and applause.

At this time, Feng Ruzheng let the plane fly higher, only to see the fuselage violently shaking, head high and tail low, out of balance, and the fuselage tilted. At that time, there was no safety belt and landing equipment to control his body, which caused Feng Ru to be thrown out of the frame and fell to the ground, seriously injured. He woke up in the hospital and said to his disciples, "After I die, don't be discouraged by this accident." Feng Ru died at the age of 28 because of ineffective treatment.

After inspection, the plane was idle for one year, and some parts rusted, which led to the failure of the controller and an accident.

After Feng Ru's martyrdom, on September 24th, the military government held a memorial meeting and paid pensions to his family. 1 161October 16, the interim president issued an order to "give a shirt to a major general who died in battle".

Feng Ru's body was buried in the Air Force Cemetery, and now it has been moved to the left of Huanghuagang 72 strong earth tomb, and a monument has been erected for future generations to pay tribute to.
