What are the Chinese characters who are unknown and selfless?

1. Qian Xuesen.

When the People's Republic of China was founded in 1949, Qian Xuesen, who was then the director of the supersonic laboratory of the California Institute of Technology and the head of the "Guggenheim Jet Propulsion Research Center", was deeply happy for the rebirth of the motherland.

He intends to return to China and use his expertise to serve the new China. However, at that time, it was not easy for Chinese scientists in the United States to return to China, and Qian Xuesen's expertise was directly related to national defense, and the United States did everything possible to keep him and prevent him from returning to China.

Second, Wen Tianxiang.

Wen Tianxiang, a national hero of the Southern Song Dynasty, was defeated and captured, sat in a dungeon for three years, and repeatedly refused the enemy's persuasion to surrender. One day, Kublai Khan, the ancestor of the Yuan dynasty, personally came to the dungeon to persuade him to surrender and promised to be the prime minister, but he did not waver, but said categorically: "I can only repay the country with death, I want nothing!" ”

Before the execution, the prison officer approached and said: "General Wen, if you change your mind now, not only can you avoid death, but you can still be the prime minister." Wen Tianxiang shouted angrily

Death is death, and what nonsense are you talking about! So, Wen Tianxiang faced the south, generosity was righteous, and Wen Tianxiang left a shocking "Song of Righteousness" before his death.

3. Nobel's eternal dedication.

Nobel was the inventor of safety explosives and smokeless gunpowder. He devoted his life to the development of explosives. After the successful development, it won a large number of patents and accumulated a lot of wealth.

In 1896, before his death, Nobel decided to give 33 million crowns as his first prize, and with the annual interest, he awarded the prize to outstanding figures in the world to promote the development of science and culture.

4. Darwin was concerned about benefiting mankind.

Darwin was frail and sickly in the second half of his life, but he continued to experiment and write books. He once said, "The zeal for science makes me forget or drive away my daily malaise." On April 19, 1882, Charles Darwin died.

In his autobiography, he wrote: "I have followed science incessantly, and dedicated my life to it, and I believe that I am right to do so, so I have no remorse, but I regret that I have not benefited humanity directly."

These words fully express Darwin's great ambition to benefit humanity.

5, the father of the two bombs - Deng Jiaxian.

Deng Jiaxian was an outstanding representative of Chinese intellectuals, and for the sake of the strength and prosperity of his motherland China and the development of China's national defense scientific research, he was willing to be an unsung hero and struggled in obscurity for decades. He often appeared in the most dangerous positions at critical moments, regardless of his personal safety, which fully demonstrated his noble and selfless dedication.

He made outstanding contributions to the development of China's nuclear **, but little is known, and it was not until after his death that people learned about his deeds. He was the most simple scientist of the peasantry. Deng Jiaxian's keen vision enabled China's nuclear development to continue to advance rapidly for ten years, and finally reached the level of laboratory simulation before the complete ban on nuclear testing.

The characters and deeds of selfless dedication are:

1, Zhang Guimei.

5, Qian Xuesen.

First as a dean and then as a vice president, Qian Xuesen's resume often has the words "vice president and president of the Fifth Academy of National Defense", but in fact, Qian Xuesen first became the dean and then the vice president. Although President Qian, who was 45 years old at the time, was full of energy, he not only had to hold a "literacy class" for China's missile industry, but also led everyone to tackle key technical problems, and he also had to worry about firewood, rice, oil, and salt for the whole family at the research institute.

Sometimes, the report of the graduate school and the report of the kindergarten will await his approval. These administrative matters took up a lot of his time to ask, for which he gave Nie Shuai.

He wrote a letter asking him to "retire" and correct himself to become a deputy and devote himself to scientific research and technological research, and his superiors agreed to his request.
