In June 1956, Li Zhengdao and Yang Zhenning jointly published the paper "Questions on Parity Conservation in Weak Interactions" in the American "Physical Review", arguing that there is non-conservation in the weak interaction of elementary particles.
As soon as this paper was issued, it caused a detonation in the theoretical physics community. On January 1957, 1, Wu Jianxiong led several scientists to complete an experiment, which confirmed the non-conservation of parity from the observation of cobalt-9 decay.
"Since the founding of quantum mechanics 30 years ago, parity conservation has been regarded as one of the fundamental laws of physics beyond doubt."
"In the mind of physicists, in two physical processes, if one process is the mirror image process of the other, then they always proceed in the same way. This is the so-called conservation of parity."
"In recent years, the research on kaons has allowed Yang Zhenning to see some phenomena that violate parity conservation, which is the phenomenon of θ-τ decay..."
"The decay phenomenon of θ and τ has inspired the concept of parity violation in the weak interaction, but it is not yet a strong evidence, because we cannot be sure that θ and τ are the same kind of meson. The experiment of Associate Professor Wu Jianxiong is To confirm whether the number of electrons emitted to both ends in the cobalt 60β decay is symmetrical..."
Tang Hua originally wanted to ask Deng Jiaxian to write this article. After all, Deng Jiaxian and Yang Zhenning knew each other when they were studying in the United States.But Lao Deng said no, I can no longer show up now.
Well, Tang Hua can explain clearly the theory of non-conservation of parity, but it is a bit difficult to "discover" it by himself. There is no high-energy physics experimental equipment in China that can compare with Berkeley and the Institute for Advanced Study in Princeton. Paper invention theory, that is to be regarded as a monster.
After writing the article, Tang Hua suddenly remembered something:
If everything goes as normal, the Chinese, to be precise, the citizens of the People's Republic of China, will receive their first Nobel Prize by the end of this year...
Chapter 150, The First Canton Fair
An article written by Tang Hua introducing what is going on with the parity violation theory appeared on the science page of the People's Daily two days later.
Tang Hua took the newspaper and flipped through it.In order to be as simple as possible, the article is quite long and occupies a large area. The fourth edition does not reserve too much space for the "Hundred Schools of Thought" section. In this issue, only a small section is left. This article discusses Ming and Qing Confucianism.
Since November last year, the fourth edition of the People's Daily has not been "serious".The Suez War, a large introduction to the battle situation; after the Soviet warship shot Israel, it was even worse. For a week, we said that our Eagle Strike-11 anti-ship missile is powerful, explaining why a warship can lock and strike 2 targets at the same time, etc. .
Of course, they are all vernacular words that do not involve technology-most readers of "People's Daily" can't understand the technical principles.
Then came the Olympic Games, and for more than half a month, it was expanded into a special edition for the Olympic Games. Anyway, the Controversy section is constantly being squeezed.Not only the People's Daily, Tang Hua is now the Central Committee of the Kuomintang Revolutionary Committee, and the CPPCC official newspaper has not escaped. Tang Hua, Li Siguang, Wang Ganchang, Huang Jiqing and their students took turns to dominate the page.
Tang Hua flipped through the newspaper, secretly assessing the changes in certain things.
I did it on purpose, why...
Before the college entrance examination last summer, Tang Hua really wrote a special article for middle school students who were about to take the exam.
Rolling up the newspaper and stuffing it in the corner, Tang Hua was about to get down to business.Then the phone rang.
"Tang Hua,... Dean Tang, your newspaper article said that the theory of parity violation may lead to the unified equation of electromagnetic force and weak interaction force?" Qian Sanqiang spoke extremely fast on the phone.
……
"If the physical model is reconstructed with the theory of parity violation, then I think there is something in common between the weak interaction and the electromagnetic interaction," Tang Hua said. "It's just an intuition that there is a unity between the two." possibility."
When Tang Hua came to the Institute of Atomic Energy of the Chinese Academy of Sciences in Fangshan, Zhao Zhongyao, Qian Sanqiang, Deng Jiaxian and others each had a copy of the People's Daily.
"Old Qian, Old Deng..." Tang Hua laughed, "We are working on reactors and atomic bombs, can we spend more time on reactors?"
Qian Sanqiang and Deng Jiaxian: "This thing, just thinking about it, is exciting. The unified theory of weak electricity. It is the first step of GUT."
Electromagnetic force, gravitational force, weak interaction force, and strong interaction force determine the appearance of our known universe.
The unification of the three forces is called GUT, Grand Unification Theory, and Grand Unification Theory.If universal gravitation is also unified, it can be called the theory of everything.
Einstein spent his later years working on the equations that would unify the electromagnetic and gravitational forces, but to no avail.
Tang Hua: "I don't want to do any GUT... It's too far away, and it's hard to say whether I can see it in my lifetime. Deep ultraviolet lasers, carriers, quantum tunneling, plasma etching, it's so interesting to do these things."
现在T57计算机的X5600系列、学生计算机的XS3725处理器，用的是6微米工艺，也就是……6000纳米。
In line with the sequential queue of "sales generation, pocket-holding generation, process completion generation, and engineering research and development generation", Tang Hua or the Electronic Information Industry Bureau has a lot of good things hidden in his pocket.
In addition to this "four-generation queue", Tang Hua himself is also responsible for the last "theoretical preparation generation" to clarify the quantum mechanics theory of several extreme bottlenecks that chip technology will encounter in the future. If it is difficult for him to describe clearly, he will Go to the Soviet Union and get Landau or someone else to do it together.
In the first 30 years of computer technology development, quantum mechanics was used to explain the operating principles of semiconductors, and the effects of semiconductors can in turn provide examples of quantum mechanics.
After more than 30 years, the continuous development of semiconductor technology has increasingly required the theory of quantum mechanics. The computer industry needs to rely on the development of quantum mechanics to find a way to break through the bottleneck of the process, so that Moore's Law can continue to be strong.

On March 1957, 3, the 7th World Table Tennis Championships was held in Stockholm, Sweden.This year's Chinese team is not the later God team, but the national table tennis team has begun to take shape after its establishment a few years ago. Both men and women won bronze medals in team competitions.
The technical level of Chinese table tennis players this year is not yet superb, but they are already exploring their own style of play. They did not blindly follow the trend of European players. Although the speed of the ball is not fast, the reaction is quick and the spike is ruthless.
Not long after the Olympic Games, people in the country can hear the news of Chinese athletes winning cards from newspapers, radio and television, and... Unlike shooting, table tennis doesn't seem to be too difficult?
The World Table Tennis Championships made Tang Hua say again and again, "Hey, I still have to be on TV to enjoy watching."Now we can only hope that the 1959 World Table Tennis Championships can be sent back to China from West Germany through long-distance cable-optical fiber transmission.
But in March, the news that Tang Hua is most looking forward to is not the World Table Tennis Championships.

"Showa 32, the bottom of the pot is not bad!" "
(The bottom of the pot is not going well = the bottom of the pot is depressed)
The 1957-1958 economic crisis was Japan's first mine.
The causes and consequences of Japan's mine explosions start with last year's Suez War.
At that time, Japan misjudged the situation. Seeing three Soviet warships rushing into the Mediterranean Sea and fighting, they thought that a large-scale and high-intensity local war or even a full-scale war would break out in the Middle East. Therefore, Japan frantically imported oil, coal, Iron ore, various industrial raw materials, and semi-finished products are piled up under Tokyo Bay, and the Showa men wrapped in oil paper can only be picked up temporarily to make room for them.
This time Japan miscalculated, Britain and France quickly admitted their cowardice, and the British teachers were too weak.
Due to the sharp increase in speculative imports and the reduction of foreign exchange led to financial austerity, in March 1957, domestic demand fell, and the government's inventory investment fell sharply. rate increased.By the end of March, some Japanese newspapers had discovered that something was wrong, the economy had stagnated, and the Great Depression cycle had begun.
However, the Japanese government does not admit it, and insists that although it is a bit difficult now, it is still far from a depression. We are still in a business cycle, but we have encountered some setbacks temporarily, which can be called "boom boom".Japanese newspapers immediately borrowed this stalk and invented the new term "pot depression".
As for the UK, since November 11 last year, the UK's financial market has not slowed down. Financial problems have made it increasingly difficult for companies to obtain loans, and the economy has gradually declined.But unlike Japan's sharp decline, the UK's decline is at a constant speed, and it reaches the critical point of depression later than Japan.
In March 1957, there was a phenomenon of unsalable goods in the United States, which was a bad omen.Unsalable goods did not lead to price declines. On the contrary, the U.S. consumer price index rose by 3% from March to April, further weakening the competitiveness of exports.The United States has not yet exploded mines, but it may be more serious when it explodes.
……
In the noisy and pessimistic atmosphere, on April 1957, 4, a large group of British businessmen and European businessmen came to Guangzhou from Hong Kong, and the first Canton Fair officially opened.
From the preparation of a large-scale import and export fair at the end of last year to April, the so-called preparatory period in the past few months is actually the Chinese embassy and business personnel contacting everywhere, looking for foreign businessmen who are particularly brave to come to China. Looking for businessmen who want to buy Chinese goods, but also looking for businessmen who dare to sell goods to China.
The European business group that came to the first Canton Fair had a total of more than 200 businessmen and their entourages, including more than 120 independent businessmen.In addition to Europeans, more than 50 Indonesian and Malaysian Chinese/Chinese businessmen with Indonesian permanent residence qualifications also came to the Canton Fair.
In January 1955, most of the members of the "Icebreaker" business group who transited from Hong Kong to China also came, including Jack Perry, the head of the Icebreaker.Andrew Short and Silva Westland, who have made some deals with China, are among them.
Headed by chief accountant and foreign trade minister Ye Jizhuang, and Guangdong Provincial Party Secretary Tao Zhu, the Chinese reception staff welcomed foreign businessmen in front of the venue.
"When I came to China last time, I said I was a ceramics merchant," Westland said to Ye Jizhuang, "Mr. Ye, this time I really plan to buy some ceramics. Now I... do all kinds of business."
Ye Jizhuang shook hands with Westland: "Of course we have ceramics, which is a long-established line of Chinese people. There are more other products, all kinds of things. If you like it, just sign the order!"
