1972, Yang Zhenning came to China for the second time. The authorities approved Deng Jiaxian to receive his childhood friends in his home. The old furniture was hurried away. Specially sent carpenters to polish an old bookcase in Deng Jiaxian, hastily put on a mirror, and made a "brand-new" wardrobe in one day; The worn floor was waxed, and someone moved the sofa from the office, bringing excellent varieties of watermelon, chocolate and a box of soda. It's like setting a scene on the stage. Deng Jiaxian acquiesced.
On the night when Yang Zhenning came, there was a special movie in the yard to attract people to the cinema. The building looks strangely quiet. As soon as Yang Zhenning entered the door, he looked around and went straight to the bookshelf. This is the bookcase of a pure medical expert, except for two Mao Zedong works in the most conspicuous position and a thick stack of specially placed postcards of the motherland.
Yang Zhenning turned around and stared at his friend with smiling eyes. As early as 1964, he saw Deng Jiaxian's name from the report of China's first atomic bomb in American newspapers. He didn't want to discover, just nodded slightly, as if to say, you cleaned up very clean.
The atmosphere of this meeting is much more lively than the first meeting of 197 1. That was in the hotel, and this time it was at home after all. Eating watermelon and drinking soda, Yang Zhenning bluntly commented that China "can't arouse people's enthusiasm", talked about the China "Cultural Revolution" tabloids he collected in the United States, and talked about the FBI. Suddenly, he asked, "Is this your home?"
"Yes, yes", Deng Jiaxian unified answer in advance. "This is the dormitory of Xu Luxi Medical College."
"Why is there no son's bed?" Yang Zhenning is very clever.
When the "living room" was renovated, my son's bed was indeed removed. Deng Jiaxian didn't expect the Nobel Prize winner to be so accurate. In spite of this, Xu Luxi is very witty. She quickly covered up: "My son lives in grandpa's house."
Later, Deng Jiaxian invited Yang Zhenning to eat roast duck. With him, Deng Jiaxian always feels a little nervous. He was afraid that his childhood friends would suddenly ask about his work. But Yang Zhenning seems to have forgotten this. Both physicists are deliberately choosing non-physical topics.
The play didn't end until Yang Zhenning left Beijing for Shanghai. Deng Jiaxian went to the airport to see him off. When he sent his old friend to the tarmac, Yang Zhenning turned around and was silent for a while. Finally, he asked, "Jia Xian, I heard in the United States that an American helped China build an atomic bomb. His name is Joan Hinton. Is this true? " Deng Jiaxian a face of consternation. He opened his mouth excitedly, but immediately bit his lip. It was a long time before he said, "Get on the plane first."
Shortly after the plane vacated, Deng Jiaxian immediately reported to his superiors and asked for instructions on the problems encountered. Premier Zhou Enlai gave clear instructions: You can tell Mr. Yang that all the atomic bombs in China were developed by China people themselves.
Excited, Deng Jiaxian couldn't wait to write a letter and immediately sent someone to Shanghai by civil aviation flight. Yang Zhenning received this dispatch at the farewell banquet held by the Shanghai Revolutionary Committee. When he opened the envelope and saw Deng Jiaxian's familiar handwriting-"It was all developed by China people themselves", his eyes filled with tears.
1957, when Yang Zhenning went to Sweden to accept the Nobel Prize in Physics, the jury asked him to provide an English speech. Yang Zhenning replied, "No, I want to write in Chinese." The jury said, "Chinese speeches cannot be printed." He replied firmly, "Then please copy my manuscript."
Yang Zhenning often flies from America. Deng Jiaxian's home is his calm and warm harbor, and he is free beside Deng Jiaxian.
-You find me a bike!
-What?
-Let's go to Xiangshan to play together!
I dare not. Can others do it? !
That's a real pity. Then let's talk about something, the theorem of the non-conservation of the universe. Gauge field theory?
Usually, their conversation is just a piece of paper and a pen.
That day, after a meal imitation and relaxed conversation, Yang Zhenning suddenly asked: "Jiaxian, from the atomic bomb to the hydrogen bomb, the Americans used it for seven years, the Soviets used it for more than three years, the British used it for four years, and the French used it for eight years. Why did China only take two years and eight months? "
Deng Jiaxian didn't speak. His look suddenly became serious. He knew that this was a question mark in Yang Zhenning's heart for a long time, and a trace of apology floated to his heart, but he could not satisfy his friend's desire to explore. This is not a person's secret, but a nation's secret to the world. Silence is the silence between the desire to understand and the desire to be understood.
After the imitation meal, Mr. and Mrs. Deng Jiaxian accompanied Yang Zhenning to the Beijing Library, and Yang Zhenning wanted to consult a rare book of ancient books. Xu Luxi later vaguely remembered that it was a book written by an ancient philosopher in China. After reading it, Yang Zhenning wrote the following words in Xu Luxi's notebook: seemingly plain, clear, difficult, easy, complicated and simple. On the afternoon of May 30th, 1986, Yang Zhenning went to the hospital to visit Deng Jiaxian shortly after the operation. When he and Deng Jiaxian talked about the progress of cutting-edge science in the world, Deng Jiaxian's forehead was beaded with sweat.
June 13 is the day when Yang Zhenning left Beijing and returned to the United States. He came to the hospital again. Two hands-the hand playing squash, the hand writing physical formulas-hold and hold-are real farewell, not "goodbye" anymore.
