What other stories of patriotic scientists do you know?

1, Zhan Tianyou, the father of Chinese railways.

Zhan Tianyou, a pioneer of modern science and a famous engineer, was ordered to build the Beijing-Zhangjiakou Railway with patriotic enthusiasm in the face of the difficult situation of domestic lack of funds, technology and talents. With the spirit of selflessness and hardship, he traveled all over the mountains between Beijing and Zhangjiakou. It took only 5 million yuan and four years to build the Beijing-Zhangjiakou Railway, which foreigners planned to spend 9 million yuan and took seven years to build.

All the foreign experts who came to visit were shocked and surprised. At that time, in recognition of Zhan Tianyou's achievements, an American university decided to award him a doctorate in engineering and invited him to attend the ceremony. But Zhan Tianyou was responsible for the design of another railway, so he resolutely declined the invitation. His spirit of serving the country rather than the individual has won praise at home and abroad.

2. Hua returned to China.

1950, mathematician Hua gave up his professorship in the United States and returned to the motherland. On his way home, he wrote an open letter to students studying in the United States, which said: "In order to choose the truth, we should go back;" For the sake of the nation, we should go back; To serve the people, we should go back; Even for personal development, we should go back as soon as possible, lay a solid foundation for our work and strive for the construction and development of our great motherland. "

After returning to China, Hua studied applied mathematics, covering 23 provinces, municipalities and autonomous regions, and solved a large number of practical problems in production with mathematics, so he was called "people's mathematician".

3. Geologist Li Siguang.

Li Siguang, a famous geologist, studied hard at Birmingham University in England for six years in his early years and obtained a master's degree in geology. His teacher, Professor Baldwin, advised him to continue his studies and return to China after obtaining his doctorate. Li Siguang declined the teacher's kindness. He replied, "No, I want to contribute what I have learned to my motherland as soon as possible." 1920 resumed work until 1937 when War of Resistance against Japanese Aggression broke out.

Later, when he went abroad, he insisted on going abroad for geological research. By 1950, he gave up the favorable conditions abroad and made a detour from England to return home when everything was in ruins in New China. As the geological minister of New China, he has made outstanding contributions to the petroleum industry in China.

4. Two bombs of Deng Jiaxian.

After China's "father of the two bombs" Deng Jiaxian received his doctorate, the United States will give him good conditions and generous treatment, hoping that he can work in the United States for a long time. However, Deng Jiaxian did not waver in his determination to return to work because of his high official position and generous salary. 1950, he returned to the motherland with the ambition of serving the country and made outstanding contributions to the successful development of the "two bombs".

5. Physicist Zhou Peiyuan

Zhou Peiyuan, a famous contemporary physicist in China, was invited to participate in the research work of the United States wartime scientific research and development agency 1945. With the end of World War II, the U.S. Admiralty established a naval military industrial test station, hoping that Zhou Peiyuan would work in the station with good treatment.

However, the Admiralty is a government department of the United States. When you work in a unit under the Admiralty, you become a civil servant of the United States government. Foreigners must join the United States to participate. Zhou Peiyuan immediately put forward three conditions to the US: First, not to join American citizenship; Second, only undertake temporary research tasks; Third, you can leave at any time. 1947 February, Zhou Peiyuan resolutely left the United States with his wife and children and returned to the embrace of the motherland.
