Chapter 339 338【Invitation】

Einstein has been arguing with the Copenhagen School on the issue of quantum theory for three years, and neither party can convince the other, nor can they prove that the other party is wrong.

In the course of the debate, Einstein was slightly at a disadvantage.

Every morning at the Fifth Solvay Conference, Einstein presented a novel thought experiment that attempted to demonstrate that quantum theory had internal contradictions. But his scientific opponent, Bohr, can always come up with reasonable answers to Einstein's doubts that night.

So much so that in the meeting that lasted more than a month, every attack by Einstein made Bohr's theory more consolidated and perfected.

Until now, Einstein has not dared to completely deny the quantum theory as he did at the beginning, and can only say that the existing quantum theory lacks completeness and reality.

And this thought experiment about cats hits the core of the "Copenhagen Interpretation" and the "uncertainty principle" it developed.

According to the existing interpretation of quantum mechanics, the cat in the box is in a "dead-alive superposition state", being both dead and alive. You have to wait until the box is opened to see the cat before you can decide its life or death.

Note that it is "decision", not "know".

Therefore, Einstein called the cat experiment the most powerful evidence against the Copenhagen School, because it can make the "uncertainty principle" unbreakable.

Einstein was very happy about this, and he said: "Mr. Zhou, the sixth Solvay Conference will be held in October this year. I hope to quote your thought experiment."

"Of course, it is my honor to be able to participate in the top contemporary scientific debate." Zhou Hexuan laughed.

Einstein asked, "How did you come up with this experiment?"

Zhou Hexuan said: "In fact, I don't know much about physics, and the knowledge level only stays in Newton's "Mathematical Principles of Natural Philosophy". Regarding quantum mechanics, I only recognize and think about it as philosophy. I have understood your debates. , came up with this experiment in a flash of inspiration.”

"A very wonderful idea." Einstein laughed.

Zhou Hexuan said: "But I am not opposed to quantum mechanics. Maybe it's just that human beings' research on the quantum field is not yet mature enough. With the advancement of science and technology, quantum mechanics can achieve more dazzling achievements. For example, quantum communication can replace existing communication methods. .”

"Quantum communication?" Einstein was noncommittal, and did not dwell on this issue.

If Zhou Hexuan was a physicist, Einstein might still argue, but Zhou Hexuan's rank is too low, and he doesn't even bother to refute it with professional knowledge.

It is a pity for Einstein that quantum theory has reached a dead end. He belongs to one of the pioneers of quantum theory, but because of unresolvable scientific contradictions, he embarked on the road of opposing quantum mechanics.

The two stopped talking about scientific issues, but talked about the current economic crisis in the United States. Zhou Hexuan asserted that European countries such as Britain, France and Germany will be affected and affected by the United States, and the industrial production level of the capitalist world will undergo a major regression.

Immediately afterwards, the two talked about the social system from the economic crisis.

Einstein expressed concern about the political situation in Germany, as the number of seats for the Nazi Party continued to increase, and Nazi Party propaganda could be seen and heard everywhere.

The Nazi Party has been better in the past two years, pointing the finger of speech at other political parties and the existing political system. A few years ago, it was scary enough, saying that the Jews had invaded the living space of the Aryan nation. If Germany wanted to revive, all the Jews had to be expelled, or even killed.

Zhou Hexuan said: "What the Nazis preached was actually militarism. After Hitler came to power, he would inevitably implement dictatorship step by step. The situation in Japan is similar now. Militarists openly propagandize on the streets and encourage Japan to invade China by force. When the world economic crisis As the situation becomes more and more serious, when the civilians in Germany and Japan cannot afford to eat, they will inevitably be bewitched by these war elements, and they will transfer domestic conflicts to the people of other countries through war.”

"I agree with you very much, but unfortunately the fascists can no longer be stopped." Einstein was very worried.

In fact, Einstein signed the Anti-Fascist Manifesto as early as three years ago, and was elected as the honorary chairman of the International Anti-Imperial League. He is a leftist in thought, agrees with the idea of ​​communism, supports the Soviet Union, and opposes imperialism and fascism.

Zhou Hexuan took the opportunity to say: "Looking at China's current national strength, it is very difficult to resist the Japanese invasion. We must not only develop industry, but also develop science. China built two national-level research institutes last year. At present, they are only grassroots. The level is limited, and it needs the guidance of experienced scientists. If possible, I hope that Mr. Einstein can go to China for academic exchange activities. He can even serve as an honorary member of two Chinese research institutes."

Einstein was not withdrawn, and he was happy to do academic exchanges and hold various honorary positions. In the past few years, Einstein has been visiting abroad almost every year, traveling around South America, North America, the Middle East, and the Soviet Union. He is even a director of the Hebrew University and an academician of the Soviet Academy of Sciences.

If Zhou Hexuan did not send out the invitation, Einstein would discuss the truth with Tagore this summer, visit the United States in winter, and even take a playful photo with Indian natives, and make a statement on the world disarmament statement of the "International Women's Peace and Freedom League" signature.

This is a restless master. He has entered his old age and has basically published all the scientific theories that should be published. He devotes a lot of energy to social activities, and his efforts in scientific research have decreased sharply.

After careful consideration, Einstein said: "I have more time before May."

Zhou Hexuan smiled and said, "Then how about we set off next month? Taking the train from the Soviet Union can save a lot of time."

"No problem, it's settled." Einstein said.

Einstein even had a plan. After the trip in China, he could stop by Japan and then take a boat to the United States without wasting any time.

After Zhou Hexuan bid farewell to Einstein, he immediately sent a telegram to Li Shizeng in France and Cai Yuanpei in China, asking them to prepare a reception plan.

Li Shizeng and Cai Yuanpei were delighted to hear the news, and Cai Yuanpei immediately notified the Nanjing Nationalist Government.

The Nanjing National Government attached great importance to this, and the Ministry of Education, the Ministry of Foreign Affairs and other departments immediately took action, and many domestic celebrities and scholars also responded one after another, hoping to participate in Einstein's reception and accompanying work. The major colleges and universities almost fought, and they all hoped to invite Einstein to give lectures in their schools.

Accompanied by Jiang Zuobin, Zhou Hexuan visited the Soviet ambassador to Germany.

It was finally decided that everyone would set off in early February, go to Moscow first, and then return to China along the Trans-Siberian Railway.

Just when they stepped on the train, far away in the United States, "Titanic" was finally published.
