What works does Qian Xuesen have?

1. "Engineering Cybernetics" "Engineering Cybernetics" is a Chinese scientist Qian Xuesen (Tsien, H. S.) The English work written in 1954 was published by McGraw-Hill in the United States; it was later translated into a simplified Chinese version and published by Science Press.

2. He is the author of Engineering Cybernetics, System Engineering, Introduction to Interstellar Navigation, etc.

3. In the same year, after the deliberation and approval of the International Asteroid Center and the International Asteroid Nomenclature Committee, the international number 3763 discovered by the Zijin Mountain Observatory of the Chinese Academy of Sciences was officially named "Qian Xuesen Star".

4. "Qian Xuesen". Introduction: "Qian Xuesen" is a biographical film released by Western Film Group Co., Ltd. and the Television Art Center of the General Equipment Department of the People's Liberation Army of China on March 2, 2012. Directed by Zhang Jianya and co-starring Chen Kun, Zhang Yuqi and Zhang Tielin.

Li Siguang's systematic scientific view

1. Discussing the history of "academic thought" of Chinese geological science over the past hundred years, put it on the balance of philosophy. To measure the treatise of the older generation of geologists in China, Mr. Li Siguang's systematic view of systematic science should be the first. .

2. Guided by the overall view of the earth system advocated by Li Siguang, various natural disasters are regarded as a natural disaster system, and the research on the relationship between the natural disaster system and the earth's surface system and the interrelationship between heaven, earth and life has been comprehensively carried out.

3. Geological system science is the science of studying geological systems from the overall view of the system. It is the development and extension of geological mechanics and a branch of earth system science. At present, the international geoscience community has formed a consensus that earth system science is the forefront of earth science research. This aspect of research starting from Li Siguang should be advanced.

4. The core of Li Siguang's academic thought is the overall view of the earth system, but the level of geological mechanics research is mainly to study the tectonic system from the overall view of the system. Therefore, if Li Siguang's overall view of the earth system is to be scientificized, it seems that it needs to experience the innovation and development of geological mechanics-geological system science-earth system science trilogy.

As a famous scholar, how did Qian Xuesen write his introduction in 200 words?

1. Qian Xuesen Qian Xuesen (191111-). Applied mechanics, aerospace technology and system engineering scientist. Born in Shanghai, originally from Hangzhou, Zhejiang Province. Graduated from Shanghai Jiaotong University in 1934. Received a master's degree from Massachusetts Institute of Technology in 1936. Received a doctorate degree from California Institute of Technology in 1938. Returned to China in 1955.

2. World-famous scientist, aerodynamicist, the founder of China's manned spaceflight, the "father of China's science system" and the "king of rockets". Thanks to Qian Xuesen's return to China, the launch of Chinese missiles and atomic bombs has been advanced for at least 20 years. Qian Xuesen was born in Shanghai in 1911, and his ancestral home is Lin'an City, Hangzhou City, Zhejiang Province.

3. Biography Qian Xuesen (1911~X), a Chinese scientist and rocket expert, was born in Shanghai on December 1, 1911. He came to Beijing with his father at the age of 3. He graduated from the Department of Mechanical Engineering of Shanghai Jiaotong University in 1934 and went to the United States to study aviation engineering and aerodynamics in 1935. He received a doctorate degree from California Institute of Technology in 1938.

4. Qian Xuesen's brief introduction is as follows: Qian Xuesen (December 11, 1911 ~ October 31, 2009), born in Shanghai on December 11, 1911, and his ancestral home is Hangzhou, Zhejiang Province.

On System Introduction to Engineering

When editing "On System Engineering (Revised)", the style in the book was determined according to Qian Xuesen's opinion. Therefore, when the new century edition of this book is published, except for correcting the errors in the text in the book and indicating the writing time and source of each article, no other changes will be made to reflect the style of the original book.

On System Engineering, On Thinking Science, On Geographical Science, Art of Science and Art of Art, On Human Science and ModernScience and Technology, "Creation Systematics", "On Macro Architecture and Micro Architecture", "Qian Xuesen on Rockets, Missiles and Aerospace", etc.

Judging from the reality of reform and opening up, not only economic system engineering, but also social system engineering is needed. Systems Science Qian Xuesen's most important contribution to systems science is that he has developed the methodology of systematics and open complex megasystems. Thinking science Artificial intelligence has become an international hot topic, but academic thought is in a state of chaos.

The Outstanding Alumni Award of the California Institute of Technology in the United States; the "Two Bombs and One Star Merit Medal" awarded by the Central Committee of the Communist Party of China, the State Council and the Central Military Commission in 1999, and the "50th Annual Highest Honor Award of China's Aerospace Industry" in 2006, etc. His works include Engineering Cybernetics, Systems Engineering, Introduction to Interstellar Navigation, etc.
