I am a lonely stranger in a strange land, and I miss my family more often during the holidays.

Two months after the outbreak of the Revolution of 1911, Qian Xuesen was born in Shanghai, and the national tragedy became his first memory. In order to save the country, Qian Xuesen, who graduated from middle school, chose engineering as the direction of his life struggle, just like many aspiring young people at that time. 1In the summer of 934, 23-year-old Qian Xuesen completed his major in mechanical engineering at Shanghai Jiaotong University and was admitted to the preparatory class for studying abroad in Tsinghua University. A year later, Qian Xuesen traveled across the ocean to study for a master's degree in aviation at MIT.

With an impulse to win glory for our country, Qian Xuesen got his master's degree in just one year. 1936, Qian Xuesen transferred to California Institute of Technology, and obtained a doctorate in aviation and mathematics three years later. Subsequently, under the guidance and cooperation of his teacher and world mechanic master von Carmen, Qian Xuesen began the research on aerodynamics, solid mechanics, rockets and missiles of high-speed aircraft, participated in a lot of engineering practice, and worked with colleagues to design and develop the first generation missiles for the United States, laying a reliable theoretical foundation for the establishment of the world aviation industry.

Qian Xuesen rose to fame and became as famous a scientist as von Carmen. The US Army invited him to teach rocket and jet technology, and the US Air Force used his jet propulsion as an internal teaching material. From 65438 to 0947, 36-year-old Qian Xuesen became a young full professor at MIT, with a position, reputation and comfortable life that many people dreamed of.

Qian Xuesen was never prepared to live in America for a long time. He clearly knows that this is just a post station in his life, and the distant motherland is his eternal home. During his 20 years in the United States, Qian Xuesen didn't buy a dollar of insurance. He applied the wind tunnel principle to the calculation of windmill power generation, and the selected height is from sea level to 8 kilometers above sea level, which is the natural condition of his motherland, China.

Many years later, Qian Xuesen said, "I spent the first three or four years in the United States studying and the last ten years working. All this is in preparation for doing something for the people after returning home. Because I am from China. "
