Brief introduction of Qian Weichang's life

One of the San Qian we often talk about is a world-famous scientist, educator and social activist. Qian Weichang +093 1 was admitted to Tsinghua. After that, he made great achievements in many fields and became the moving China of that year.

Introduction to Qian Weichang: 193 1 year, Qian Weichang was admitted to Tsinghua University with five points in physics, 20 points in mathematical chemistry and two full marks in Chinese. After the September 18th Incident, Qian Weichang decided to study physics instead of literature. 65438-0940, Qian Weichang went to Canada to study, majoring in flexibility. In 194 1- 1942, Qian Weichang mainly studied the reactance in the radar waveguide and the vibration of the square plate clamped in tension. 1942 received his Ph.D. from the Department of Applied Mathematics, University of Toronto. From 1942 to 1946, Qian Weichang is the chief engineer of the Jet Propulsion Research Institute of California Institute of Technology, and is a student of von Carmen in the world. Qian Weichang has been engaged in the research of rocket trajectory, rocket aerodynamic design, meteorological rocket, satellite orbit, parachute and other scientific fields, and published the world's first singular perturbation theory paper, becoming the founder of this field.

From 65438 to 0946, Qian Weichang returned to China and worked as a professor in Tsinghua University, Peking University and yenching university. 1954 to 1958, deputy to the first people's congress of China. At the same time, Qian Weichang became honorary chairman of NLD, and successively served as president of Shanghai University, Nanjing University, Nanjing University of Aeronautics and Astronautics, Jiangnan University and Jinan University. Qian Weichang's major achievements are in physics, applied mathematics, China informatics, elasticity, perturbation method and variational principle.

In Qian Weichang's introduction, I learned that Qian Weichang made great contributions to mechanics and was one of the founders of mechanics. Moreover, Qian Weichang is very concerned about China's education, being humble and becoming a model for the younger generation.

Who is Qian Weichang's son?

Qian Yuankai, son of Qian Weichang and Kong, is a camera authority and digital imaging expert in China. He used to be the chief engineer of Beijing Camera Factory and a member of China Photographers Association. Qian Yuankai has been engaged in photography teaching for a long time and is called "Qian Yuankai who won't ask" by the photography community.

Qian Weichang's son Qian Yuankai became an amateur photographer on 1968. In his spare time, he made seven cameras, exposure meters, magnifying glasses, flashlights and other photographic equipment and various camera testing instruments. Qian Yuankai joined the Beijing Camera Factory Research Institute as the chief designer from 1982 to 1994, during which he participated in the development of various cameras. Among them, "EF3" camera won the Beijing Science and Technology Achievement Award and the first prize of the National Camera Competition.

Qian Weichang's son, Qian Yuankai, was the chief engineer of Beijing Sufi Company in 2002. 1994. During his tenure in this company, he established the first series of slit grating stereo image production system in China, and put it into commercial operation, obtaining a number of patents. 1994, served as the editorial board of Photography and Videography and Digital Photography. In 2006, Qian Yuankai was hired as distinguished professor of the New York Institute of Photography.

Qian Yuankai, the son of Qian Weichang, a famous scientist, lost the opportunity to go to college because his father was classified as "Rightist" when he was growing up. However, Qian Yuankai listened to his father's instruction and became a self-taught person. Qian Yuankai's achievements, including his papers and works, have devoted a lot of his efforts. From 1989 to 1998, Qian Yuankai worked as a writer in the column Photography in China. During this period, he published many articles in China Photography and other photography magazines.

The relationship between study and money

Qian Weichang and He are both famous scientists and scholars in China and even the world. They are similar in age, both enjoy a long life span, and the time of death is very close, but their fate and destiny are completely different. The only notable similarity between Qian Xuesen and Qian Weichang is that they are both descendants of Theodore von Kármán, a scientific genius in the space age.

Qian Weichang and Qian Xuesen

Qian Xuesen was born in Shanghai on 19 1 1. He is the thirty-third grandson of Ren Yue, a native of Hangzhou, Zhejiang. He is a world-famous scientist and aerodynamicist, the founder of manned space flight in China, an academician of China Academy of Sciences and China Academy of Engineering, and the winner of China's two bombs and one satellite meritorious medal. Compared with Qian Weichang, Qian Xuesen seems to be more famous. He is known as "the father of China's space flight", "the father of Chinese missiles", "the father of China's automatic control" and "the king of rockets". Some people even said that China's aviation industry was at least 20 years ahead of schedule because Qian Xuesen returned to China.

Qian Weichang is one of the founders of modern mechanics in China, a famous scientist, educator and social activist. Qian Weichang 19 12 was born in Wuxi, Jiangsu, and 193 1 was admitted to Tsinghua University. Qian Weichang's life is legendary. He abandoned literature and reason when he was a student, leaving a beautiful talk that "the needs of the motherland are my major". Qian Weichang has ideas and opinions. In 1950s, when China's educational science and technology system copied from the Soviet Union, Qian Weichang bravely stood up and opposed it, and did not hesitate to fight it with his political life.

In terms of academic contributions, Qian Weichang and Qian Xuesen have their own strengths. Qian Weichang is not as good as Qian Xuesen in space flight, but Qian Weichang's contribution is better in mechanics research and education.

However, Qian Xuesen and Qian Weichang were both leading figures in the field of modern scientific research in China, and together they became "San Qian".
