Viewing the character Qian Xuesen has feelings, Qian Xuesen s character evaluation

1. In the 40s of the 20th century, Qian Xuesen has become one of the most outstanding representatives in the field of aerospace, and one of the very few superstars in the scientific stars in many disciplines in the 20th century.

2. The award speech that moved the Chinese Organizing Committee to award Qian Xuesen was that in his heart, the country is the most important, the family is the lightest, science is the most important, and fame and fortune are the lightest. Five years to return to the country, ten years to achieve two bombs. He was the pioneer in creating the motherland's aerospace, cutting through thorns and thorns, forging wisdom into a ladder for later climbers.

He is a treasure of knowledge, a banner of science, and a model of intellectuals of the Chinese nation. Honoring the balancer's liquid.

Qian Xuesen is the beloved son-in-law of Mr. Jiang Baili, a famous Chinese military scientist. In order to save the motherland in danger, Qian Xuesen first went to the United States to study and seek knowledge, but when he returned to China, he was forcibly detained by the United States.

After going around for several years, he finally returned to the embrace of the motherland, devoted himself to the construction of the motherland, and made great contributions in World War II and to the development of China's missile and aviation science.

In the 1962 book "Introduction to Interstellar Navigation", the concept of a space-to-earth transportation system with a large aircraft equipped with a jet engine as the first stage carrier and an aircraft with a rocket engine as the second stage carrier was proposed.

Ask the child how to write about Qian Xuesen's experience in the third grade.

Qian Xuesen (today) is a famous Chinese physicist and a world-famous rocket expert. A native of Hangzhou, Zhejiang, born in Shanghai, Han nationality, joined the Communist Party of China in August 1959, with a doctorate, and is known as the "father of Chinese missiles", "the father of Chinese rockets", and "the king of missiles".

Qian Xuesen is a great patriot, in October 1955, under the care of the older generation of proletarian revolutionaries, he broke through many obstacles, returned to the socialist motherland, and joined the Communist Party of China honorably in October 1958. Although the conditions of manpower and material resources were very poor at that time, he enthusiastically devoted himself to the work of cutting-edge scientific research and personnel training for China's national defense with boundless love and loyalty to the motherland and the people, and made historic and outstanding contributions to the establishment and development of China's rocket, missile, and aerospace undertakings.

Born on December 11, 1911 in Hangzhou, Zhejiang, he joined the Communist Party of China in August 1959 with a doctorate degree.

From 1929 to 1934, he studied in the Department of Mechanical Engineering of Jiaotong University, and after graduation, he applied for Tsinghua University to study in the United States as a public-funded student, and after being admitted, he interned at Hangzhou Jianqiao Airport. From 1935 to 1939, he studied at the Massachusetts Institute of Technology in the Department of Aeronautical Engineering, where he received a master's degree. From 1936 to 1939, he studied at the Department of Aeronautics and Mathematics at the California Institute of Technology, USA, and received a doctorate.

From 1939 to 1943, he was a researcher in the Department of Aeronautics at the California Institute of Technology. From 1943 to 1945, he was an assistant professor in the Department of Aeronautics at the California Institute of Technology (during which he was a correspondence researcher at the Chengdu Institute of Aeronautics in Sichuan from 1940 to 1945).

From 1945 to 1946, he was an associate professor in the Department of Aeronautics at the California Institute of Technology. From 1946 to 1949, he was an associate professor and professor of aerodynamics in the Department of Aeronautics at the Massachusetts Institute of Technology. From 1949 to 1955, he was director and professor of the Jet Propulsion Center at the California Institute of Technology.

I just learned a text called "Qian Xuesen". After reading it, I was in awe of Qian Xuesen. When Qian Xuesen was in the United States, he was the most proud student of American aerodynamics von Kármen.

At that time, he enjoyed a favorable treatment in the United States, a wealthy life and excellent working conditions. But he has not forgotten his homeland for a moment, and he wants to return to his homeland as soon as possible. After Qian Xuesen returned to China in October 1955, he made outstanding contributions to our carrier rockets and missiles, and was known as the "father of China's missiles".

At that time, China was a poor country, and it was really difficult to conduct scientific research because it had no money or equipment. However, in order to enable the motherland to move from darkness to light, Qian Xuesen finally made outstanding contributions to the motherland with his own efforts. So he is not only a "father of Chinese missiles", but also a patriot.

What I remember most is what Qian Xuesen said in the United States: "I am Chinese." Everything I am doing now is to prepare, so that I can do more for the motherland and the people when I return to the motherland.

Qian Xuesen worked hard to complete his studies in the United States, just so that he could serve the motherland and the people more after returning to China. This sentence fully reflects the patriotic sentiment of Qian Xuebei Busen's selfless dedication.

Qian Xuesen can give everything for the motherland, so why can't we do our best to make a little contribution to the motherland? Therefore, we must hold the mood of making the motherland stronger and stronger, study hard, and make the motherland stronger and more prosperous!
