1881may1kloc-0/day, von Carmen was born in Budapest. His father is the famous von Carmen and Qian Weichang of the historic Peter Pai smark University in Budapest.
Professor of education. His mother was born in a scholarly family, and there was a famous mathematician in the16th century. At the age of six, Von Carmen could give the answer by thinking about the multiplication of five digits. His father is worried that he has extraordinary computing ability, and he is afraid that he will become a deformed man in the future. Soon, with his father's intervention, von Carmen cut all kinds of math subjects and didn't start studying math again until he was a teenager. His father asked him to read geography, history and poetry instead of doing math exercises, and he has always been grateful to his father. Because he advocated humanistic civilization all his life, this is inseparable from his father's letting him get rid of math games from an early age. Father's greatest help and cultivation to Von Carmen is to stimulate his curiosity about knowledge. He often asks his father some religious questions. He never saw any contradiction between science and religion, which may be related to discussing religious issues with his father in his early years.
Edit this legendary story
German rocket scientist Wernher von Wernher von braun once said: "von Carmen is the most outstanding veteran in the aerospace field. He was far-sighted and sensitively created von Carmen and Qian Xuesen.
Being creative and good at organization ... is his uniqueness. In view of von Carmen's outstanding contributions in the fields of science, technology and education, the US Congress awarded him the first National Medal of Science. On the morning of February 1963 and 18, celebrities and guests gathered in the White House Rose Garden, and the award ceremony was about to be held. When Lao Feng Carmen walked down the steps, he was unstable because of severe arthritis and almost fell down. The young president quickly stepped forward and caught him. The old man raised his head with a grateful smile, then gently pushed away the hand extended by the president and said simply, "Mr. President, people who go downhill don't need help, only those who climb high need help." A medal with the highest honor, pun intended, is a legendary portrayal of his life: the medal marks his great achievements in science and technology, while the punch line depicts his colorful personality and keen attention to science. In the 20th century, science and technology developed rapidly. However, people who dominate space technology like von Carmen are rare and almost extinct. Therefore, it was praised as "a scientific wizard in the space age" by later generations.
Edit the personality description of this paragraph.
The size of scientific achievements is often related to the personality quality of scientists themselves. Carmen's success is partly attributed to his cheerful, humorous, independent and democratic temperament. As a great man, dignitaries, rich people, military and political dignitaries tried their best to make friends with him, and Carmen was willing to associate with them. He belongs to the upper class. However, Carmen is not a snob. He will not hesitate to introduce a gardener to dignitaries without discrimination. He once said that Einstein's sincere and kind soul is exactly what he has been pursuing all his life. Von Carmen
Carmen is humorous, cheerful and talkative. He likes to fall in love and will surprise me with some strange fragments. His witty tone often makes those serious and stuffy people laugh. Carmen is also good at combining fun with career. He has a special ability. On the surface, he is engaged in some activities, but his mind is engaged in his own scientific thinking. He often slips out of the party for an hour or two to deduce an equation or write a paper, and then casually comes back to continue his topic. Carmen's cheerful and unrestrained personality is also reflected in his teaching and educating people. He believes that there is no distinction between teachers and students, only between contribution and academic qualifications, and teaching and learning are complementary. In teaching methods, he advocates simple and intuitive ways, omitting minor details, grasping the essence, adopting image analogy and intuitive illustration, and explaining according to the average level of students. It is said that when Carmen deduces the formula, she often falls into a dead end set by herself, and then gets rid of it with superb skills. The students sometimes held their breath quietly and sometimes exclaimed. To the student, it seems that he is playing with a puppet to bring the dead things back to life. It is in this lively and tense atmosphere that Carmen imparted knowledge to the students. In addition, Carmen also advocates the democratic style of study of free discussion and encourages free creation. People sit around, play chess, chat and, more importantly, exchange academic ideas. White tablecloths are often filled with mathematical equations, and many ideas are bred in this unrestrained atmosphere. This kind of academic discussion advocated by Carmen not only broadens students' thinking, but also stimulates their creative enthusiasm. Carmen's teaching method was fully exerted when he was the director of GALCIT (abbreviation of aviation research laboratory) from 65438 to 0929, and achieved excellent results. Someone once compared him with Leonardo da Vinci in the Renaissance, thinking that Leonardo da Vinci created novel parts, while Carmen trained a large number of outstanding talents. His students are all over five continents, and he is known as "Carmen Cobain". He has made outstanding contributions to education. Von Carmen is undoubtedly a veritable scientific genius. His outstanding achievements in aviation are beyond dispute. Some of the most outstanding theories in aerospace, von Carmen
The concepts are all named after him, and there is also a crater named von Carmen on the moon. And milestones in aviation history, such as led zeppelin, wind tunnel, glider and rocket ... It can be said that the success of all actual and simulated flights in the 20th century is closely related to him. He braved the wind and waves and made great achievements in space technology, opening a new chapter in space history. Carmen's career success is admirable, and her ideological personality is as admirable as her life. Although he was somewhat vain in his later years, he was not bossy or senile. After 70 years old, he still travels around the world and works for the progress of the world and mankind. And the "Carmen Coban" he cultivated will be remembered by the world forever. Nowadays, this generation of romantic figures has gone away from us. However, flying objects in the blue sky and white clouds will be engraved with that name-Theodore von Kármán.
Edit this life
Von Carmen/KOOC-0/88/KOOC-0/May/KOOC-0//KOOC-0/was born in Budapest, Hungary. He is the youngest of three brothers and has a sister. Von Carmen's grandfather is a famous Jew and his father is a professor at Budapest University, which has a good influence on the growth of Von Carmen. 1902, von Carmen completed his research project at the Royal University of Technology in Budapest and obtained a master's degree. 1903- 1906 works in the university of technology and is a consultant of an engine factory in Hungary. He has done some valuable work on aircraft structure and material strength. During this period, he also went to the University of G? ttingen to study for a doctor's degree. He studied under Professor ludwig prandtl, one of the pioneers of modern fluid mechanics, and obtained the doctor's degree 1908. In the first decade of the 20th century, shortly after the invention of the airplane, the news of the Wright brothers' successful test flight spread to Europe, which set off a "flying fever" in Europe, especially France, and a group of indomitable aviation pioneers emerged, among which Farman was one. 1908 One day, Von Carmen witnessed another record-breaking flight of farman. After the flight, Von Carmen pushed his way through the crowd and had a wonderful conversation with the pilot. Von Carmen asked Farmer, "I study science. A great scientist used his laws to prove that things heavier than air can never fly, so why ... ". Farman replied humorously, "Is that the person who studies apple falling?" Fortunately, I haven't read his book, otherwise I won't get the bonus for this flight today. I am just a painter, a racing driver, and now I am a pilot. As for why the plane flies, it's none of my business. As a professor, you should study it. I wish you success, goodbye! "On the way home, Von Carmen sat in a speeding car and meditated for a long time. He said to a reporter accompanying him: "It seems that the words of great men are not necessarily right. Now I have finally decided what I should study for the rest of my life. "Von Carmen held the reporter's hand out of the window, and immediately a gust of wind blew through his hand. He said: "I will spare no effort to study the wind and study all the mysteries of flying in the wind." One day I will explain to Farman why his plane can go to heaven. "It was this visit that made von Carmen devote his life to the research of aerospace aerodynamics. Soon, his teacher Pelant invited von Carmen to be his assistant at the University of G? ttingen to engage in teaching and research. 19 12, von Carmen became the director of the Institute of Aerodynamics of Ahern University. He worked there for 14 years and made many important breakthroughs in aerodynamics. He also served as a consultant for some enterprises to develop airships, all-metal transport planes and rockets. From 65438 to 0926, von Carmen moved to the United States to guide the design and construction of the Guggenheim Aerodynamics Laboratory and the first wind tunnel of California Institute of Technology. During his tenure as director of the laboratory, he summarized the theory of blunt body resistance, that is, the famous "Carmen Vortex Street" theory. This theory greatly changed the accepted aerodynamic principle at that time. He also put forward the boundary layer control theory and the future supersonic drag principle in 1935. 1938, von Carmen guided the United States to conduct the first supersonic wind tunnel test and invented the jet-assisted take-off, making the United States the first country to use rocket boosters on airplanes. Under his guidance, a group of aviation engineers of California Institute of Technology, including his beloved China disciples Qian Weichang, Qian Xuesen and Guo Yonghuai, began to study jet propulsion and liquid fuel rockets, mechanics and applied mathematics, and thus established a jet propulsion laboratory. The laboratory is the first research unit of the US government engaged in long-range missiles and space exploration, and has many important research achievements, including the first theory on singular perturbation published by Qian Weichang under his guidance, and Qian Weichang is internationally recognized as the founder of this field. Von Carmen made a great contribution to human supersonic flight. After 1932, many papers and research results on supersonic flight were published, and the supersonic drag of slender body in three-dimensional flow field was calculated for the first time by using small disturbance linearization theory, and the concept of shock resistance in supersonic flow and the important point that reducing relative thickness can reduce shock resistance were put forward. 194 1 published a famous formula for calculating the wing pressure distribution in high-speed flight-"Carmen Qian Xuesen's formula", that is, von Carmen corrected the wing pressure distribution in subsonic airflow by applying the viewpoint of Qian Xuesen in 1939. 1946, von Carmen proposed the transonic similarity law, which combined with Pelant's subsonic similarity law, Qian Xuesen's hypersonic similarity law and acle's supersonic similarity law to form a complete basic theoretical system of compressible aerodynamics. In the same year, he delivered an important speech entitled "Theory and Application of Supersonic Aerodynamics" at the 10 Wright Brothers Memorial Lecture, announcing that the supersonic era was coming. 19471June14th, the X 1 rocket plane designed by von Carmen finally broke through the sound barrier for the first time, bringing mankind into the era of supersonic flight. At the end of World War II, General Arnold, commander of the US Army Air Force (predecessor of the US Air Force), asked Professor von Carmen to evaluate the current situation of the development of American aviation technology, predict the development in the next 20, 30 or even 50 years, and make suggestions on how to ensure the leading position of the US Air Force in the future. 1 944 65438+February1day, the army aviation formally established a scientific advisory group headed by von Carmen. Its task is to evaluate the trend of aviation research and development and prepare special reports on scientific and technological affairs for the Air Force. 1in the early summer of 945, von Carmen was ordered to lead a 36-member advisory group of the US Air Force with the rank of Major General to Germany to inspect Nazi Germany's secret research on rocket technology. Through this investigation, von Carmen found out the level of German rocket technology. After returning to the United States, he first wrote an investigation report "Where Are We", which compared the scientific and technological development of the United States and Germany during the war and pointed out that it was possible for the United States to develop a missile with a range of 9,600 kilometers. Then, von Carmen published his second report, entitled "Towards a New Horizon". The report includes 32 sub-reports by 25 authors, covering topics ranging from aerodynamics and aircraft design to explosives and terminal ballistics. The main point of the report "Towards a New Horizon" is that "science is the basis of mastering air superiority". The report emphasizes that there is no once-and-for-all way to become an aviation power. Only by continuously strengthening research and development can national security be ensured. The report predicts that new combat capabilities will surely emerge one after another, supersonic flight will become possible, satellites and long-range missiles with considerable accuracy will be developed, and turbojet and turboprop engines will make significant progress. 1950, von Carmen won the American Air Force Association Award. All the recommendations in the report were well implemented in the US Air Force, such as the establishment of the Aviation R&D Command, which was later reorganized into the Air Force System Command, and was independently responsible for the R&D work of the entire Air Force. Von Carmen 1963 died on May 7th. The funeral procession included China, Japanese, Europeans and Jews. There are Muslims and Christians; There are military generals and well-known scientists; And his close friends and assistants. In the anthology commemorating the 50th anniversary of the founding of the US Air Force, many people think that among all Arnold's contributions to the future development of the US Air Force, the most important thing is that he relied on von Carmen to lay a solid foundation for the establishment of the US Air Force through science and technology. Thanks to the continuous technological innovation, the US Air Force has been able to ride the wind and waves all the way, including the great victory of the US Air Force in the 199 1 Gulf War, all of which are the results of technological progress initiated by Arnold and von Carmen.
