1, Zhan Tianyou doesn't care about fame and fortune: Zhan Tianyou, a pioneer of modern science and a famous engineer, faced with the difficult situation of domestic lack of funds, technology and talents, was full of patriotic enthusiasm and was ordered to build the Beijing-Zhangjiakou Railway. 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 resolutely returned to China: After the July 7th Incident, the great mathematician Hua returned to War of Resistance against Japanese Aggression's motherland, not for money or for a degree, and actively participated in the anti-Japanese national salvation movement after returning home. 1950, he became an internationally renowned first-class mathematician and was hired as a tenured professor by the University of Illinois, but he resolutely led his family back to the newly liberated motherland.
3. Nobel's eternal dedication: Nobel is the inventor of safe explosives and smokeless gunpowder. He devoted his life to the development of explosives. After the successful development, it obtained a large number of patents and accumulated a lot of wealth.
1896, before Nobel died, he decided to use 33 million kronor as a fund, plus annual interest, to reward outstanding people in the world, so as to promote the development of scientific and cultural undertakings. Fu said in his will: regardless of nationality, race and language, this bonus is only for those who really make indelible contributions to mankind. Nobel has devoted his life to science, and the Nobel Prize will always promote the development of science and culture.
Darwin's thought is beneficial to mankind: Darwin was weak and sick in the second half of his life, but he still insisted on doing experiments and writing books. He once said: my passion for science made me forget, or drove away my daily discomfort.
1April 882, Darwin died. He wrote this passage in his autobiography: I have been following science and devoting my life to it. I believe it is right for me to rely on it, so I won't feel sorry, but I regret that I didn't directly benefit mankind. These words fully show Darwin's great ambition to benefit mankind.
5. Two Bombs of the Founding Fathers-Deng Jiaxian: 1850, 26-year-old Deng Jiaxian returned to China after receiving a doctorate in physics in the United States. The motherland welcomed the "Baby Doctor" with warm embrace, and Deng Jiaxian was immersed in the joy of youth and family happiness. However, history is changing, and the motherland is threatened by nuclear powers. Deng Jiaxian resolutely accepted the important task of developing the nuclear cause of the motherland, left his wife and children behind, and went to the Great Gobi.
Since then, he has disappeared from the podium of physics. More than 20 years later, Deng Jiaxian came back with the sand in the Gobi Desert in his hair, and the fame of the two founding fathers began to spread, and Deng Jiaxian's name reappeared among ordinary people. At this time, his wife is over 60 years old, but the cancer demon has already been injected into his body, and his brilliant life has burned to the end. His last words to his wife before he died were: I will die without regrets!
