What are the deeds of dedicated people?

Deeds of dedicated people:

1. Zhan Tianyou served the country regardless of fame and fortune: Zhan Tianyou, a pioneer of modern science and a famous engineer, had no capital, no technology, and no capital in China. Faced with the difficult situation of having no talents, he was full of patriotic enthusiasm and was ordered to build the Beijing-Zhangjiakou Railway. With his selfless spirit of hard work, he traveled through the mountains and ridges between Beijing and Zhangjiakou, and spent only 5 million yuan and 4 years to complete what foreigners planned to invest 9 million yuan and take 7 years to complete. Beijing-Zhangjiakou Railway.

The foreign experts who came to visit were all shocked and amazed. At that time, some universities in the United States, in recognition of Zhan Tianyou's achievements, decided to grant him a doctorate in engineering and invited him to attend the ceremony. However, Zhan Tianyou was responsible for the design task of another railway, so he refused the invitation. His spirit of serving the country rather than seeking personal fame has won praise at home and abroad.

2. Hua Luogeng resolutely returned to China: After the "July 7" Incident, the great mathematician Hua Luogeng returned to the motherland where the anti-Japanese war was burning everywhere from the UK, where living conditions were good, not for money or a degree. Actively participated in the anti-Japanese and national salvation movement. In 1950, he had become an internationally renowned first-class mathematician and was hired as a tenured professor at the University of Illinois in the United States. However, he resolutely led his family back to the newly liberated motherland.

3. Nobel’s eternal dedication: Nobel is the inventor of safety explosives and smokeless gunpowder. He devoted his life to developing explosives. After the successful development, a large number of patent rights were won and a lot of wealth was accumulated.

In 1896, before his death, Nobel decided to use 33 million kronor as a fund. With the annual interest, he awarded awards to outstanding figures in the world to promote the development of science and culture. Fu Zai said in his will: This bonus, regardless of nationality, race and language, will only be awarded to those who have truly made indelible contributions to mankind. Nobel dedicated his life to science, and the Nobel Prize will forever promote the development of scientific and cultural undertakings.

4. Darwin cared about benefiting mankind: Darwin was frail and sick in the second half of his life, but he still persisted in experimenting and writing books. He once said: My enthusiasm for science made me forget or drive away my daily discomfort.

On April 19, 1882, Darwin died of illness. He wrote this passage in his autobiography: I have continued to follow science and dedicated my life to science. I believe that it is right for me to rely on it, so I will not feel regret. But what makes me regret is that : I have not benefited mankind directly. These words fully express Darwin's great ambition to benefit mankind.

5. The hero of the two bombs - Deng Jiaxian: In 1850, the 26-year-old Deng Jiaxian returned to China after receiving a doctorate in physics in the United States. The motherland welcomed this "Doctor Baby" with open warm arms, and Deng Jiaxian was immersed in it. In the joy of youth and the happiness of family. However, history has changed, and the motherland is facing the threat of nuclear powers. Deng Jiaxian resolutely accepted the important task of developing the motherland's nuclear industry, bid farewell to his wife and children, and went to the Great Desert incognito.

Since then, he disappeared from the podium in the physics community. More than 20 years later, Deng Jiaxian came back with grains of Gobi sand in his hair. Only then did his reputation as a hero of the two bombs begin to spread, and Deng Jiaxian's name reappeared among ordinary people. At this time, his wife was already in her sixties, but the cancer had already entered his body, and his glorious life had burned to the end. The last words he said to his wife before his death were: I will die without regrets!
