Einstein is no longer in Berlin, but he has just moved into a Kaps hut in the Potsdam countryside with his wife and two stepdaughters. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The reason is this, Einstein turned 50 last year. The Berlin government promised to build a villa as a business gift for Einstein, but the plan was scrapped after the authorities debated the cost of the villa.

Enraged, Einstein simply bought a plot of land in Capuz at his own expense and commissioned the architect Conrad to build a summer house.

"Well, it's very nice here," Einstein said to Conrad, looking at the newly renovated wooden cottage, "and I'm very pleased with your work." ”

Conrad was just a young architect, and he was very respectful in front of the great scientist and smiled: "It is my pleasure, Mr. Einstein." ”

His wife, Elsa, walked out of the house and said with her hands in frustration: "It's a pity that it's too cold here, and the stove can freeze people, so it can only be used as a place to escape the heat, and it's better not to live here in winter." ”

Albert Einstein said, "It's too far from Berlin to stay long, so let's go back in two days." ”

In this way, Zhou Hexuan's lectures at the University of Berlin were over, and Einstein returned to Berlin with his wife and daughter. His lifelong personal secretary, Helen Ducasse, came over with five letters and said, "Sir, these are letters from the last few days. ”

Einstein first read the letter from the Belgian empress, then several other scientist friends, and finally opened the letter from the Chinese embassy in Germany.

After reading the letter, Einstein asked, "Does this Zhou Hexuan have any special origin?" ”

The female secretary, Helen, replied: "Mr. Zhou Hexuan is a famous Chinese historian and writer who accurately predicted the great stock market crash and economic crisis in the United States, and his novel has just won the French Goncourt Prize for Literature, and he was nominated for the Nobel Prize in Literature last year." Personally, I think it's worth seeing. ”

"Then you can arrange it for me." Einstein didn't pay much attention to it, and took out a blank letter to the Belgian Empress in reply.

In fact, since Einstein became famous, people have often wanted to visit him for more than a decade. But Einstein was still very picky, and for the whole of last year, he only met the Belgian queen and the French mathematician Adama.

The most interesting thing was the exchange with Adama, where a great physicist and a great mathematician met, and they talked about the topic of "war and peace".

Three days later, in his residence in Berlin, Einstein met with Zhou Hexuan, who had come to visit.

"Hello, Mr. Einstein."

"Hello, Mr. Zhou."

The two shook hands and greeted each other, then sat down and looked at each other curiously.

Einstein's stepdaughter Margo brought two cups of coffee, smiled and said to Zhou Hexuan, "Please use it slowly." ”

As for the female secretary, Alan, sat next to her, ready to briefly record the conversation between the two.

Zhou Hexuan couldn't help but look at Margo twice, not because he was interested in Einstein's stepdaughter, but because he remembered the gossip that had been circulated in later generations.

It is rumored that after Einstein's divorce, he was once entangled in whether to marry his cousin and cousin, or whether to marry his cousin's daughter. His cousin suggested that he take his daughter, but Einstein felt bad about the influence, so he finally married his cousin and lived with his two stepdaughters.

Einstein also had a long-term mistress in Berlin at this time, and that mistress was the best friend of his stepdaughter Margo, and her private life seemed to be very chaotic.

Zhou Hexuan retracted his gaze and said to Einstein: "It's an honor to communicate with you face to face." ”

Albert Einstein smiled and said, "You Chinese scholars seem to be so young. ”

Zhou Hexuan understood this sentence as contempt, and immediately replied: "When you created the 'miracle year', you were also very young. ”

"Haha, you're right, being young is not a sin, it's a kind of capital," Einstein heard Zhou Hexuan's dissatisfaction and changed his attitude, "I'm sorry, maybe I made a mistake just now." When I went to Shanghai a few years ago, I met several Chinese scholars, all of whom were very young. I still remember a young man named Zhang Junmai who discussed socialism with me. ”

Not only Zhang Junmao, but also Zhang Jiluan, another friend of Zhou Hexuan, was also the person who accompanied Einstein back then.

Zhou Hexuan asked: "What is your impression of China?" ”

Einstein thought for a moment and said, "It's complicated. ”

"Complicated?" Zhou Hexuan said.

Albert Einstein recalled: "I walked into a certain street in Shanghai (Nanjing Road) and the road was full of enthusiastic young students. They had fanaticism written on their faces and even lifted me up with both hands, which I had never been treated like I had ever received in other countries. They clearly respected and loved science, and I became the embodiment of science in that moment. In this sense, China is a country with great potential and hope. ”

Zhou Hexuan asked, "What else?" ”

Albert Einstein continued: "I love Chinese art, I listened to the traditional oriental opera (Kunqu Opera) in Shanghai, and although I didn't know what the actors were singing, I enjoyed it very much. Another Chinese painter named Wang Zhen invited me to his house and gave me a Chinese painting. Whether it's art or science, China has left a good impression on me. What makes me feel bad is the living conditions of the Chinese. There is a clear difference in social status between Europeans and Chinese in Shanghai. The Europeans formed a ruling class, and the Chinese were their slaves. When I tipped a Chinese waiter, it was probably too much, and he was so excited that he knelt down and kowtowed to me on the spot. Do you know? At that moment, I felt like I was back in the Middle Ages. The Chinese impressed me as a tormented, reckless, uncivilized people who had nothing to do with the country's great civilizational past. They are simple laborers, struggling to survive in labor, and they seem so ignorant and tenacious. ”

As a crosser in the 21st century, Zhou Hexuan is very touched by this, because this is also the feeling he felt when he first crossed, and said bitterly: "The Chinese are fighting, and the victory of the Northern Expedition in the first two years has not changed much in Chinese society, but on the whole it is developing in a good direction." ”

Albert Einstein said, "So I can especially understand your revolution, that China is awakening in revolution after revolution." ”

Zhou Hexuan smiled: "I heard that you are a loyal supporter of the Soviet Union? ”

"Yes, the Soviet Union was a miraculous and great form of government, and Lenin was the greatest revolutionary." Albert Einstein was really Lenin's brainless fan.

Zhou Hexuan asked: "Then you promised Lenin to return China's territory and privileges in a difficult time." But after resolving the domestic contradictions, what do you think of the Middle East Road that turned around and refused to return China? ”

"Is there such a thing?" Einstein was stunned.

"Of course," Zhou Hexuan said in detail, "in 1919 and 1920, when the Soviet Union was suffering from internal and external troubles, Lenin wanted to be recognized by the Chinese government, and repeatedly promised to return China's Middle East Road. But just a year later, Lenin took control of the Soviet Union, and he deliberately avoided previous diplomatic statements. To this day, the Soviet Union still has privileges in northeastern China. In the past few months, the Chinese wanted to take back these privileges, and the Soviet Union used tens of thousands of troops to brazenly cross the border to invade China. ”

Einstein did not understand this, he had the impression that the Soviet Union was perfect, and Zhou Hexuan's words made him puzzled and disappointed.

After a moment of silence, Einstein said: "I feel very sympathetic to the inequality that China has suffered, and I hope that there will be no more wars on the planet." ”

As an anti-war activist, Albert Einstein could never have imagined that his greatest contribution to world peace would be the development of the atomic bomb.

"Let's change the topic, otherwise it will be too heavy," Zhou Hexuan said with a smile, "I heard that you are in a debate with the Copenhagen School?" ”

Albert Einstein was surprised and said, "You also have a study in physics?" ”

Zhou Hexuan smiled: "It's purely a layman, it's just very interesting, I also wrote a science fiction novel some time ago, which will be published in the United States soon." Are you really against quantum theory? ”

"There is no objection, just that quantum theory lacks completeness and reality. Until the puzzle can be solved, quantum theory can only be used as a temporary solution, and the scientists of the Copenhagen School want to treat the temporary solution as scientific truth, which I absolutely cannot accept," Einstein laughed, "Scientific theories should be accurate and complete, can you accept that the universe is the result of God's dice roll?" ”

Zhou Hexuan suddenly remembered the famous "cat", and he said: "Mr. Einstein, can you do such an experiment." Put a radiation source, a detector that records radiation particles, a bottle of poison, and a live cat into a closed box. The detector is turned on for a time sufficient to cause a 50% chance of decay of an atom in the radiating material, and the detector records the particle. If the detector does record this time, then the bottle containing the poison will be smashed and the cat will be poisoned; Otherwise, the cat will be alive. We have no way of knowing the results of the experiment until we open the box for observation, the probability of radiation occurring is half to half, it is both decaying and non-decaying, and the poison vial is both broken and unbroken. Even more bizarre is the cat, which is both dead and alive. Outside the box, what is the state of this cat? ”

Einstein didn't take Zhou Hexuan's words seriously at first, but when he heard half of it, his brows suddenly furrowed, and his face became very exciting.

"Mr. Zhou, please wait a moment, let me think for a moment." Albert Einstein closed his eyes.

"No problem." Zhou Hexuan said with a smile.

Einstein thought for more than ten minutes, then suddenly opened his eyes and asked the female secretary to bring a pen and paper, and wrote down the words "amplitude of radiation particles", "1/√2", "∣Ψ>=1/√2{∣dead >+∣alive>}" in a small notebook.

Then there was a series of symbols and numbers, and Zhou Hexuan was dizzy and didn't know what Einstein was doing.

After waiting for more than ten minutes, Einstein threw away his pen and said with a smile: "Haha, Mr. Zhou, thank you very much for the reminder." Your experiment on cats is the strongest evidence to refute the Copenhagen School! ”
