Science is always the first productive force of creation, it can be said that there are many such cases in the surrounding areas of our lives, living and living, everywhere is an achievement that can show science and technology. Back when our country was first built, the whole country can also be described as a hundred wastes to be rebuilt, after a long period of battles, it is a great loss for us, and a key development at this time is nuclear weapons, from the original gun out of power to the founding of New China, it can be said that military strength has become the pillar of a country, and in order not to be threatened by nuclear weapons, we first need to have our own nuclear weapons.
To say that since the founding of New China, the group of people who have made the greatest contribution to national development is the two bombs and one star of the last century. Without them, our aerospace industry would remain a blank slate. It is also thanks to them that New China can catch up and catch up, and then catch up, and not fall behind.
When it comes to the two bombs and one star, I believe that everyone is most familiar with Deng Jiaxian and Qian Xuesen. Their early fates were also quite consistent, and the two had studied at a higher education institution in the United States. After completing their studies, they encountered different degrees of obstacles on the road of serving the motherland. In 1947, Deng Jia first passed the postgraduate examination in the United States, and entered the Graduate School of Purdue University in the United States the following year for further study. Due to Deng Jiaxian's outstanding achievements and extraordinary talent, he obtained a doctorate in only 1 year.
And Deng Jiaxian's talent was also seen by the US government, which originally wanted to use favorable conditions to keep him in the United States, and even mobilized Deng Jiaxian's teachers and classmates to persuade him. However, they were all politely rejected by Deng Jiaxian. In October 1950, Deng Jiaxian resolutely gave up his superior living environment and work, returned to the motherland and actively threw himself into the construction of new China.
Compared with Deng Jiaxian, Qian Xuesen's road back to China was more bumpy. Qian Xuesen stayed in the United States earlier than Deng Jia, who as early as 1935 went to the Massachusetts Institute of Technology Aviation Department for further study, the school achievements are extremely outstanding, with his ability, soon stood out among many students, the world-famous scientist at that time von Carmen because of love, he accepted Qian Xuesen as an apprentice, this is not good, Qian Xuesen's ability to make this von Carmen also very surprised, since then he attaches great importance to Qian Xuesen, it is with the help of Qian Xuesen, von Carmen and Qian Xuesen established together" Carmen-Qian Xuesen" formula, such an achievement, so that Qian Xuesen early fame in the world, a sensation.
In 1949, after learning of the founding of New China, Qian Xuesen could no longer contain his excitement and wanted to fly back to the motherland immediately and use his knowledge to contribute to the construction of the motherland. Qian Xuesen and his daughter-in-law discussed, and the husband and wife quickly reached an agreement and decided to return to China. But what Qian Xuesen and his wife did not expect was that this time they returned to China, it was difficult to move forward, and it was several years of delay.
It was also in 1949 that McCarthyism in the United States began to rise, a domestic anti-communist movement spearheaded by Senator McCarthy. During this special period, Qian Xuesen, as a Chinese, has a naturally sensitive identity. Not only was his certificate revoked for participating in classified research revoked, but in 1950, when he was about to board a ferry back home, he was detained and imprisoned by U.S. officials.
Of course, McCarthyism is only one of the reasons why Qian Xuesen was unable to return to China. Another important reason was that the then US Navy Deputy Secretary Danny Jimble said that "wherever Qian Xuesen goes, he is worth the strength of 5 divisions." ”
Qian Xuesen is engaged in research in the field of aerodynamics and rockets and missiles in the United States, and Danny Jimble's words are not alarmist. The U.S. government also attaches great importance to Qian Xuesen, preferring to put him under house arrest rather than let him return to China. In 1950, the United States detained Qian Xuesen and confiscated his home in order to find so-called evidence. During the days when he was imprisoned, Qian Xuesen could not sleep at night, and it did not take long to lose 30 pounds. It was not until the California Institute of Technology came up with bail, and the U.S. side really couldn't find evidence and continued to detain Qian Xuesen, that he was released, but this did not mean that he could leave the United States.
Finally, after 1954, due to the defeat of the United States in the Korean War, McCarthyism began to decline in the United States, and the number of people monitoring Qian Xuesen gradually decreased. Qian Xuesen, who was finally able to breathe a sigh of relief, immediately secretly entrusted someone to send a distress letter back to the motherland, and after receiving this letter, our country attached great importance to it and immediately launched negotiations with the US government. However, due to Qian Xuesen's huge military value, the US side still refuses to let go. In the end, China had to use the capture of 11 US pilots on the Korean battlefield as a chip to exchange For Qian Xuesen's freedom.
Logically, the value of these 4 pilots is also not worth qian Xuesen of the "five divisions". When the US side was hesitating, China took the lead in releasing 11 pilots to return to the United States, taking the initiative in international public opinion.
The United States has always advertised itself as a humanitarian country, and if it wants to repent, the families of these returned pilots will naturally not stop denouncing the US government, and THE US soldiers will also think about whether it is worth it to serve the government. This measure of our country can be described as making it difficult for the United States to ride the tiger and find it in a dilemma. In the end, forced by helplessness, the United States had to let Qian Xuesen return to China. On October 8, 1955, Qian Xuesen's family finally returned to the motherland where their dreams were haunted, and realized their long-cherished wish to devote themselves to the construction of new China.
Throughout modern history, the revitalization of any country is inseparable from great scientists. And it is precisely because there are countless overseas scientists like Qian Xuesen who are concerned about the motherland that China can move toward rejuvenation and prosperity.
