"Second, those responsible for the riots will be tried and severely punished. Workers and all honest citizens who encounter provocateurs should be arrested immediately and handed over to state agencies."
"Third, workers and technical intellectuals should cooperate with the authorities and take necessary measures to guarantee normal work."
Tang Hua threw the newspaper aside.
The impact of this incident on the Soviet Union is not important, but the impact on China is worth pondering.
First of all, there will be a gap between Germany and the Soviet Union. If it is used well, Germany may be more willing to directly conduct some trade and technology transfer between China and East Germany without the Soviet Union as an intermediary.
Secondly, since the 617 incident still happened as in history, it seems that Beria is almost over.
Chapter 2, Qian Tang meets
"Old Qian, I sent a liaison officer from China Resources to find you in 50 years, and let you find a chance to abandon your insurance and run away. It's a pity, it's just a little short, and the time to return to China is three years late."
"Lao Mei planted the ground for no reason. I was suffocating at that time. I must win him in the lawsuit. If I abandon the bail, I will lose 300 taels of silver here. And I was released on bail by Caltech. I don't like the US government. , I still have feelings for Caltech, and it’s a bit unethical to abandon my insurance.”
Qian Xuesen, Jiang Ying, Tang Hua, Zhou Xuan, Qian Junfu (Qian Xuesen's father), and Aunt Ye (Zhou Xuan's adoptive mother), sat around and chatted in Tang Hua's courtyard.
In the small courtyard, there are three children, Qian Yonggang, Qian Yongzhen, and Tang Hancheng, running wildly.
Qian Xuesen's family got off the train on June 6.In addition to his father, Tang Hua and his wife were also greeted on the platform.
"Caltech, I don't know how Master von Karman is doing now." Tang Hua asked Qian Xuesen when he heard about Caltech.
"I went to Caltech to see him once before I left. The old man is 72 years old and his body is average, but his spirit is still sharp."
"When you left Caltech, did you say to Dean Dubridge, 'I will plant apple trees when I go back to China'?"
Qian Xuesen: "That's what I said..."
Both Qian Xuesen and Guo Yonghuai were students of von Karman.
Guo Yonghuai is one of the founders of Cornell University's School of Aeronautical Engineering.Qian Xuesen is one of the founders of NASA (National Aeronautics and Space Administration).
Well, NASA was founded in 1958 out of the Jet Propulsion Laboratory.The reason why the Jet Propulsion Laboratory was established was that five graduate students with strange brain circuits (praise) were studying rocket technology in the 30s. A rocket accident burned down half of the dormitory building. Caltech couldn't bear it and kicked these five students out. I found a wasteland outside the campus for them to play there, don't play rockets on campus.
In this wasteland, five students who were kicked out and a student who joined later named Edward Furman built a bunch of experimental equipment, and built various rockets to test every day.Finally, in 1943, three of them got the official name: Jet Propulsion Laboratory.
The five students are Frank Malina, Wilder Arnold, Apollo Smith, Jack Parsons, Qian Xuesen.All of them, including Qian Xuesen, are in NASA's Hall of Fame.
Tang Hua (speaking to Zhou Xuan): "The universities this old Qian went to were all very good. His undergraduate degree was at Jiaotong University, and he went to the United States to study for a master's degree at MIT and a Ph. One of the top guys."
"Hehehe..." Qian Xuesen pointed at Tang Hua and smiled, "Tang Hua, I also heard about your story after I came out. The US military has been studying you for more than a year."
Tang Hua: "wtf! What have they researched?"
"I heard second-hand news, which may not be accurate. They said that you were sent to the United States by your father to study in a military academy. You were absent-minded about military training, but you were very interested in science and technology. At the Virginia Military Academy, you often skipped classes, and some You stayed away for a few days and nights. Now I guess you went to the famous universities in the eastern United States to attend cutting-edge science courses, or looked up materials in the libraries of these universities. After returning to China, you quietly ran to Yan’an, then transferred to the Soviet Union, and began to transfer Come up with the results of what you have learned and thought about.”
Tang Hua: "...Not all of them. Sometimes I drive out by myself. I actually go to Richmond to sing and watch movies, or go to Newport News to go to bars. Forget it, anyway, no one talks about it now Believe it."
Everyone present laughed.
"Tang Hua, it was only in Moscow that I realized that the Soviet Union and China have conducted laser research very deeply, which is far from the depth described in those two public papers. Although I did not have access to the laser project in Moscow, I feel that China and the Soviet Union have already divorced from the laser principle. In the research stage, it has entered the actual engineering application."
Tang Hua nodded: "It would be great if I could meet Einstein again. Stimulated radiation is a great theory. Although it is only a small discovery in his academic career, it is enough to win a Nobel Prize."
Qian Xuesen: "When I was in Moscow, the Prime Minister called and said that when I return to China, I will first visit various places to understand the state of domestic industry and technology, and then decide what I want to do. Does it mean that I will be able to see domestic lasers at that time?" research results?"
"Laser? You can see it now." Tang Hua said, "Xuan'er, bring your cat teasing pen."
……
"Tang Hua, if you see Einstein again, you will definitely let him see this laser pointer, right?"
Qian Xuesen held the laser pointer up and down, left and right, facing the table against the palm, and couldn't stop playing.
"I don't care about this, it needs permission from the central government." Tang Hua was telling the truth, "But if Einstein came to China or the Soviet Union, let him see it and not take it away, I guess he would approve it. "
"Small laser pointers, laser holographic images during armistice negotiations." Qian Xuesen listened to Tang Hua explain the principle of laser holographic images that appeared during armistice negotiations, and sighed, "It's really a wonderful world, the future is in our hands... Rockets, by contrast, may end up being a weapon of mutual assured destruction between great powers, so-called spaceflight, which even I don't quite believe will happen now."
Tang Hua: "No, lasers are also weapons. ... You will understand this when you investigate in a few days."
Qian Xuesen: "The intercontinental transport rocket is unnecessary, and there is no need for it to return."
Tang Hua caught up with Qian Xuesen's big leap of thinking in an instant: "I think the US military is already doing it now."
"They were working on MX-6 774 years ago. ... 6 years ago, plus my intercontinental transport rocket, my God, I was detained in the United States for three full years, and I wasted three years. Tang Hua you You are right, in 1950 I should have given up my bail and returned to China.”
In 1947, the United States tried to develop a ballistic missile with a range greater than 2400 kilometers.
In December 1949, Qian Xuesen was invited to give a report at the annual meeting of the American Rocket Society held at the Hilton Hotel in New York.In his report he described his blueprint for an "intercontinental transport rocket".The shape of this rocket is similar to modern launch vehicles and ballistic missiles, like a sharpened pencil.It takes off vertically from the launch pad into space, with a maximum flight speed of Mach 12 and a maximum orbital altitude of 16 kilometers.
The intercontinental transport rocket is actually a sub-orbital vehicle. After flying thousands of kilometers and re-entering the atmosphere, its manned capsule uses the atmosphere to decelerate, then turns around 180 degrees, and finally approaches the ground. When the rocket works, it stops firmly on the ground .
Suborbital rockets will also experience weightlessness. In his report, Qian Xuesen also accurately predicted the emergence of weightlessness and how to overcome it: everything will fly around, so the items in the cabin must be fixed; The sealed suit is pressurized; people can float in the cabin without walking, but it is also difficult to stop themselves from the air...
Both "Popular Science" and "Flying" magazines highlighted Qian Xuesen's vision for the future at the meeting, and the 38-year-old Qian Xuesen further established his position in the aerospace field.People began to talk about the possible successor of the American aerospace and rocketry field after von Karman retired, Qian Xuesen.
No one thought that Qian Xuesen would be forced to resign a few months later to accept the review, and then be accused of stealing secrets.
In 1951, the U.S. Air Force announced that the technical conditions were ripe for the development of a ballistic missile with a range of 6000 miles (9600 kilometers).
That is, in this year, the U.S. Air Force signed a contract with Convair to develop the "Atlas" intercontinental missile. The "Atlas", which entered service in 1959, was a poorly used ICBM, but a very useful launch vehicle in the early 60s.
……
"Don't worry, old money. The development cycle of ballistic missiles is long. It is a strategic weapon, no more than tactical missiles such as air defense and anti-ship. If there is no such thing, it is very passive strategically, but we can take advantage of the peace of the past few years. It doesn't matter if you get him out a few years later than the United States."
Qian Xuesen: "I'd better start the investigation in China as soon as possible."
Tang Hua: "Then according to the schedule, inspect the electronics industry and the computer industry first, and let me show you around."
……
Electronic Information Industry Bureau, Beijing Computer Institute.
"I also heard rumors in the United States that China and the Soviet Union may have surpassed the United States in computing technology. But I am not surprised by this. The founder of information theory is right in front of me. It is normal for China and the Soviet Union to lead in this field .”
Qian Xuesen said to Tang Hua while walking in the computer office.
"Computer is a complex system. Making a computer and making a good computer is not only based on theory, but also a system behind it..." Tang Hua said, "Old Qian, have you ever used a computer in the United States?"
"Of course, before I was dismissed, I often used it. I used it in ENIAC, I used it in minicomputers made by Caltech, and I used computers purchased by the US military."
Opening the door of the second hall of the computer institute, Tang Hua and Qian Xuesen saw four computers in front of them: T50, T51, T52, and T53.
“我们的通用型计算机都以T字打头，后面跟的数字是年份。T50是1950年2月制成并且出售的；T51是1951年2月，以后的T52、T53，基本上也是在2月份左右正式推出。”
