Einstein and the Copenhagen School have been arguing about quantum theory for three years, and neither side has been able to convince the other or prove the other wrong. Pen ~ fun ~ pavilion www.biquge.info

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

At the Fifth Solvay Conference, Albert Einstein presented a novel thought experiment every morning in an attempt to prove that there are internal contradictions in quantum theory. But his scientific opponent, Bohr, was always able to come up with a reasonable answer to Einstein's questions that night.

So much so that in the more than month-long meeting, every attack of Einstein made Boer's theory more consolidated and perfected.

Until now, Einstein did not dare to completely reject 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 goes straight to the heart of the "Copenhagen interpretation" and the "uncertainty principle" it has developed.

According to the existing quantum mechanical explanation, the cat in the box is in a "dead-alive superposition", both dead and alive. You have to wait for the box to open and take a look at the cat before you can decide whether it lives or dies.

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

Therefore, Einstein called the cat experiment the strongest evidence to refute the Copenhagen School, because it can make the "uncertainty principle" self-defeating.

Albert Einstein was very pleased with this, and he said: "Mr. Zhou, the sixth Solvay Conference will be held in October this year, and I would like to be able to cite your thought experiment. ”

"Absolutely, it's an honor to be part of the top scientific debate of our time." Zhou Hexuan said with a smile.

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

Zhou Hexuan said: "In fact, I know only half of physics, and my knowledge only stays at Newton's "Mathematical Principles of Natural Philosophy". As for quantum mechanics, I just think about it as a philosophy. I've learned about your arguments, and I came up with this experiment in a flash of inspiration. ”

"Very wonderful idea." Albert Einstein laughed.

"But I'm not against quantum mechanics. Perhaps, it is just that the current research on the quantum field is not mature enough, and with the progress of science and technology, quantum mechanics can achieve more dazzling achievements. For example, quantum communication is replacing existing means of communication. ”

"Quantum communication?" Einstein was noncommittal, and he didn't dwell on the issue.

If Zhou Hexuan was a physicist, Einstein might have argued, but Zhou Hexuan's rank was too low, and he didn't bother to refute it with professional knowledge.

Quantum theory has reached a dead end, which is actually a pity for Einstein. He was one of the pioneers of quantum theory, but because of unsolvable scientific contradictions, he embarked on the path of opposing quantum mechanics.

The two did not talk about science anymore, but about the current economic crisis in the United States. Zhou Hexuan asserted that Britain, France, Germany, and other European countries would be affected and influenced by the United States, and the level of industrial production in the capitalist world would regress greatly.

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

Albert Einstein expressed concern about the political situation in Germany, as the Nazi Party's membership was growing and Nazi propaganda could be seen and heard everywhere.

The Nazi Party has been doing better in the last two years, pointing the finger at other parties and the existing polity. It was scary enough a few years ago, saying that the Jews had encroached on the living space of the Aryan nation, and that if Germany wanted to revive, it had to expel all the Jews, or even kill them.

Zhou Hexuan said: "What the Nazis preached was actually militarism, and after Hitler came to power, he would inevitably implement dictatorship step by step. The situation is similar in Japan now, where militarists openly propagate in the streets and encourage Japan to invade China by force. When the world economic crisis becomes more and more serious, and the civilians of Germany and Japan have no food to eat, they will inevitably be bewitched by these war-torn elements and transfer the internal contradictions to the people of other countries in the form of war. ”

"I very much agree with you, but unfortunately it is no longer possible to stop the fascists." Albert Einstein was worried.

In fact, Albert Einstein signed the anti-fascist manifesto three years ago and was elected honorary president of the International Anti-Imperialist League. He was an ideologically leftist figure, identified with communist ideas, supported the Soviet Union, and opposed imperialism and fascism.

Zhou Hexuan took the opportunity to say: "Judging from China's current national strength, it is difficult to resist Japan's invasion. We must develop not only industry, but also science, and China established two state-level research institutes last year. At present, it is still only a grass start, and the academic level is limited, and it needs the guidance of experienced scientists. If possible, I hope that Mr. Einstein will be able to go to China for academic exchange activities. He was even able to serve as an honorary member of two research institutes in China. ”

Einstein's personality 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 almost every year, running around South America, North America, the Middle East, the Soviet Union, and even being a director of the Hebrew University and an academician of the USSR Academy of Sciences.

If Zhou Hexuan had not sent out an invitation, Einstein would have discussed the truth with Tagore this summer, visited the United States in the winter, and even took a playful photo with the indigenous Indians and signed the world disarmament statement of the "International Women's Alliance for Peace and Freedom."

This is an idle master, he has entered his old age, the scientific theories that should be published are basically published, a lot of energy is devoted to social activities, and the effort in scientific research has been drastically reduced.

After careful consideration, Einstein said, "I had more time until May. ”

Zhou Hexuan smiled: "Then how about we leave next month?" Taking a train from the USSR can save a lot of time. ”

"No problem, that's it." Albert Einstein said.

Einstein even had plans to stop by Japan and then take a boat to the United States after his trip to China, without wasting the slightest bit of time.

After Zhou Hexuan said goodbye to Einstein, he immediately sent a telegram to Li Shizeng in France and Cai Yuanpei in China, asking them to prepare their reception plans.

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

The Nanjing Nationalist Government attaches 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, hoping to participate in Einstein's reception and accompaniment. The major universities almost got into a fight, and they all wanted to invite Einstein to give lectures at their schools.

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

In the end, it was decided that the group would leave for Moscow in early February, and then return home along the Trans-Siberian Railway.

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