When it comes to famous physicists in my country, Qian Lao is definitely the first person who deserves it. When we mention him today, what comes to mind the most should be the story of his tortuous return to China. At that time, he was highly respected abroad, and when he learned that our country was in urgent need of high-end talents, he made up his mind to come back and build the motherland.
Qian Lao's patriotic heart allows us to see the thoughts of many young people living abroad in that era through him. They hope to be able to return to their motherland, and hope to use their minds and knowledge to create a beautiful motherland in people's minds.
It is against this background that our country has embarked on many major projects based on this group of people. At that time, Mr. Qian Xuesen also dug a "big hole" for the physics community. Until now, the whole world is still jumping into it, what kind of pit is this?
01 Qian Lao's life.
Before unraveling the mystery, let's first understand Mr. Qian Xuesen's life. For his life history, when you look at it, everyone will be amazed, he is really one of the great men. Mr. Qian Xuesen was born in Shanghai, which had become a concession for the invaders.
Qian Lao, who lived in the ** period, won a place to study abroad at public expense with his excellent grades, and entered the famous Massachusetts Institute of Technology in the United States. He learned a lot Xi knowledge, including mathematics, physics, aerospace, etc., and his excellent grades and excellent abilities have attracted a lot of attention.
Later, in 1955, he successfully returned to his homeland. Of course, before returning to the motherland, Qian Lao also experienced many hardships. The United States hoped that he would continue to stay and serve them, but he firmly rejected all their preferential treatment.
At that time, China was in ruins, and many young people in China wanted to go abroad to learn Xi knowledge and technology, and then return to the motherland to build their hometowns. Not to mention, those young people who were already studying abroad Xi, when they knew that the motherland needed it, most of them returned to China after completing their studies.
At that time, like Qian Lao, there were not many people who insisted on returning to the motherland despite the retention of foreign countries. It is also because of this group of people that our country has the ability to carry out a series of research activities. These activities, carried out by outstanding young people who have returned to China, have laid a solid foundation for the future development of the motherland.
At that time, China's military industry was too weak, which was why Mr. Qian Xuesen insisted on coming back. His return has given China a backbone in rocketry, aerospace and other research fields. At the same time, he also came up with a lot of ideas that were ahead of his time, and the so-called "big pit" was one of those ideas.
02 Hypersonic flight.
At that time, although China's military industry was weak, the military contest between the Soviet Union and the United States had already begun, and the international community was constantly in dispute. The United States and the Soviet Union were keen to devote their money to research that could produce great power.
Moreover, at that time, missiles and anti-missile systems had already appeared, and the trajectory of the missile's operation could be accurately detected by the anti-missile system. Therefore, in the military war, the Soviet Union and the United States kept investing. They all hope to be able to develop more advanced technology to solve the problem of interception and counter-interception.
However, this problem, which was not solved by the Soviet Union and the United States at that time, was solved by an idea put forward by Mr. Qian Xuesen. At that time, he proposed hypersonic flight and Qian Xuesen's ballistic theory. To put it simply, they are extremely fast and have an irregular flight trajectory.
That is to say, once the trajectory and speed are beyond the scope of the anti-missile system and can be intercepted, then this missile will be invincible in the world. This is also the core secret of Chinese martial arts - only fast and unbreakable.
It is precisely because of such advanced ideas that Mr. Qian Xuesen dug this big hole, which attracted the participation of everyone one after another. At that time, China did not have enough funds and technical capabilities to support Mr. Qian Xuesen's research on this idea that was ahead of the times.
The fact that he did not study it at that time did not mean that the motherland had given up on the idea he proposed. On the contrary, it was the temporary shelving due to the lack of ability at the time that allowed future generations to do it in one fell swoop. With the technical support for the study of this idea, our country and even the world have invested great enthusiasm, which led to the later research results.
03 Dongfeng Express.
When we mention hypersonic flight today, the first thing that comes to mind should be Dongfeng Express. That's right, this rocket, which can be launched in various places, uses the theory of hypersonic flight. Of course, there are not a few military industries in the world that use the theory of hypersonic flight, but it does not mean that there are many such countries in various countries.
It can be said that this kind of fast-flying, precise strike, which can deter the enemy and play a decisive role in the key to war, is not common. Fortunately, we are one of the owners. In fact, China's Dongfeng Express not only has hypersonic speed, but also combines Qian Xuesen's ballistic theory.
That is, the Dongfeng missiles in our country are not only fast, but also have unfixed trajectories. Such a missile makes the anti-missile system completely ineffective. This is also the most attractive place in these big pits dug by Mr. Qian Xuesen.
Of course, everyone is committed to studying these advanced theories and wants to be the first to make a breakthrough. Fortunately, even though there were no conditions for research at that time, China still put these advanced ideas put forward by him in the first place in research. Therefore, today, we can gain a place on the big stage of the world's military industry.
04 Epilogue. Mr. Qian Xuesen has put forward many advanced theories, but the biggest "big hole" he dug for the physics community is still hypersonic flight. According to this theory, physicists all over the world are continuing to do research. Fortunately, everyone finally achieved certain results.
For the country, such a tool can become a tool to protect the people's stable life. I think that when Mr. Qian Xuesen studied these theories, he also hoped that his own ideas could protect the stability and happiness of Chinese's future lives.
