What are the relevant deeds of Qian Weichang?

Qian Weichang's experience tells us: believe in yourself, grasp the opportunity, and move forward bravely. Discover your own strengths and weaknesses, and develop your strengths and avoid weaknesses. Constantly challenge personal limits and surpass yourself.

Chinese is the foundation for cultivating learning ability, and in the basic education stage, seemingly boring rote memorization is the only way to truly be clever and achieve great talent. No matter whether a person wants to study literature or science in the future, or how smart and talented he was when he was a child, it is impossible for him to become a great talent in the future if he has not experienced such a large amount of memorization training when he was young.

From righteousness to physics, from solid to fluid, alternating between good and bad, unyielding, nameless, unrepentant, affectionate and intentionally with the motherland.

A person may be very intelligent and may possess a lot of knowledge, but if he does not have a noble character and a strong sense of social responsibility, he will not only not be able to benefit society, but may harm society.

Refers to the "father of China's aerospace" and "the father of China's missiles" Qian Xuesen, the "father of modern Chinese mechanics" Qian Weichang, and the "father of China's atomic bomb" Qian Sanqiang. "Sanqian" is an outstanding figure in China's scientific circles and the world's top scientists.

1. Qian Xuesen:

The 33rd grandson of Qian Biao, King of Wuyue, was born in Shanghai, and his ancestral home is Lin'an, Hangzhou City, Zhejiang Province. He is a world-renowned scientist, aerodynamicist, the founder of China's manned spaceflight, an academician of the Chinese Academy of Sciences and the Chinese Academy of Engineering, and a winner of the China Meritorious Service Medal for Two Bombs and One Star.

Known as the "Father of China's Aerospace", "Father of China's Guided Missile", "Father of China's Automated Control" and "King of Rockets", due to Qian Xuesen's return to China, China's missile and atomic bomb launches have been pushed forward by at least 20 years.

2. Qian Weichang:

He is also good at applied mathematics, mechanics, physics, and Chinese informatics, and has important achievements in the fields of elastic mechanics, variational principle, and perturbation methods.

3. Qian Sanqiang:

Nuclear physicist. Originally from Huzhou, Zhejiang, born in Shaoxing, Zhejiang, he is the founder of China's atomic energy science industry, the founder of China's "two bombs and one satellite", and an academician of the Chinese Academy of Sciences.

In 1932, he graduated from the preparatory department of Peking University. In 1936, he graduated from Tsinghua University. In 1939, Qian Sanqiang completed his doctorate** - "The Collision of Particles and Protons".

At the end of 1946, he was awarded the Henri Debar Prize in Microphysics of the French Academy of Sciences. In 1948, he served as a professor in the Department of Physics of Tsinghua University, vice president of the Chinese Academy of Sciences, president of Zhejiang University, vice president and honorary chairman of the China Association for Science and Technology, and vice chairman and chairman of the Chinese Physical Society. Society.

On July 24, 1980, Professor Qian Sanqiang delivered a speech entitled "Outline of Scientific and Technological Development" in Zhongnanhai.

Summing up Qian Weichang's life with the word legend has been quite eclipsed, he was born in a scholarly family, and wrote a 450-word fu in only 45 minutes during the college entrance examination, and he scored full marks in language and history.

Peking University talented women program speech, Qian Weichang, do you know his story, it is amazing for my countrymen!

Yes, he was admitted to Tsinghua University, and he scored full marks in Chinese and history, but he only scored five points in physics.

Qian Weichang is the father of modern Chinese mechanics, a world-famous scientist, educator, outstanding social activist, and an outstanding leader of the China Democratic League. Academician Qian Weichang is also a director of applied mathematics, physics, and Chinese informatics, and has published a lot of books—especially in the fields of elastic mechanics, variational principle, perturbation methods, etc. The creator of the world's singular perturbation theory formulated the first 12-year scientific plan for New China and published China's first monograph on "Elastic Mechanics".

Qian Weichang was born on October 9, 1912 in Qifangqiao Village, Hongsheng Township, Wuxi County, Jiangsu Province. At the beginning of the 20th century, China was in the midst of overthrowing the imperial system, establishing a republic, learning from the West to the East, and declining from the West. Qian Weichang was born in a poor family of poets and calligraphers who had a foundation in Chinese studies and founded a new school.

In Wuxi, the land of fish and rice adjacent to Taihu Lake, in order to prosper the family, the Yizhuang system is also continued. Due to the early death of his grandfather, who was a private school teacher, Qian Weichang's father Qian Shengyi (Qian Zhi) and uncle Qian Binsi (Qian Mu) relied on receiving grain and rice from the Qian family's Yizhuang to study hard. They set up their first new-style primary school in their hometown of Qifangqiao, and went to teach in other primary schools.

As a teenager, Qian Weichang sometimes lived in his father's and uncle's teacher's dormitory. When he was 16 years old, his father Qian Shengyi died of illness, and he studied in Suzhou with his uncle. Later, his uncle Qian Mu went to Peking University to serve as a professor of general history of China at the same time as Hu Shih, and became a famous master of Chinese studies.

His mother, Wang Xiuzhen, was kind and hardworking, in addition to housework, she also raised silkworms, peach blossoms, and pasted matchboxes to supplement the family. The impoverished early life and the virtuous character of his mother helped to create the spiritual strength to support him independently throughout his tortuous life. His wife, Kong Xiangying, graduated from the Department of Chinese Literature of the Faculty of Arts of National Tsinghua University, and has been his faithful companion in life and spirit for 50 years, as well as a guarantee for his career success.

Qian Weichang is an internationally renowned scientist and academician of the Chinese Academy of Sciences. In middle school, he was very fond of liberal arts, but he was afraid of science, especially mathematics and physics. Interestingly, he devoted his life to research and teaching mechanics and applied mathematics, and made many pioneering contributions in these academic fields.

He was the first to apply tensor analysis and differential geometry to the study of elastic plates and shells, and established a unified theory of thin plates and thin shells, and proposed a system of nonlinear differential equations based on the theory of linear shells, which is known as "Qian Wei's long equation" in the world. He was also the first to successfully use the system perturbation method to deal with nonlinear equations, and it is still used to deal with such problems in the world.
