In 1950, mathematician Hua Luogeng gave up his tenure as a tenured professor in the United States and ran to the motherland. On his way back, he wrote an open letter to students studying in the United States, in which he said: "In order to choose the truth, we should go back; for the sake of the country and the nation, we should go back; to serve the people, we should go back.
Even for the sake of personal future, we should go back as soon as possible to establish the foundation of our work and strive for the construction and development of our great motherland." After returning to China, Hua Luogeng conducted research on applied mathematics and traveled to 23 provinces, municipalities, and autonomous regions across the country. Mathematics solves a large number of practical problems in production and is known as the "people's mathematician".
3. Nobel’s eternal dedication
Nobel is the inventor of safety explosives and smokeless gunpowder. He devoted his life's energy to developing explosives. After the successful development, a large number of patent rights were won and a lot of wealth was accumulated.

4. 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 "baby" with open warm arms. Doctor", Deng Jiaxian was immersed in the joy of youth and the happiness of his 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, with grains of Gobi sand in his hair, came back. Only then did his reputation as "the hero of the two bombs" begin to spread, and Deng Jiaxian's name reappeared among ordinary people.
At this time, his wife was already over 60 years old, but the cancer had already been injected into 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 with no regrets!"
5. Darwin was dedicated to benefiting mankind
Darwin was frail and sick in the second half of his life, but still persisted Experimenting and writing books. He once said: "My enthusiasm for science made me forget or drive away my daily discomforts." 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 I regret is that I did not benefit mankind directly." These words fully express Darwin's great ambition to benefit mankind.
