The American Physical Society organizes dozens of conferences a year, but the ones that can make an impact in terms of scale are the March conference on solid-state physics and the April conference on particle physics.

In March 1980, the meeting was held in Manhattan, New York, when Fisher took Zheng Jianguo to stay at the Kaiyue Hotel, he didn't expect to see a blonde Dongwang accompanied by a woman with the same blonde hair coming to him, Zheng Jianguo looked at the other party in a daze and passed by himself, and he felt that the eyes of this goods were long on the door of his head when he walked.

"Do you want to change history?"

When this thought flashed through Zheng Jianguo's mind, Dongwang, who had already passed by, also turned to look at him, and then turned around and went away with the blonde in the Cadillac car at the door.

With a faint regret in his heart, Zheng Jianguo believed that if he greeted the other party, then even if he changed history in a sense, after all, there was no intersection between the two of them, but think that they have come here, so maintain the original historical trend, so that the things in his memory can happen according to the original trajectory?

"Hey, Zheng, let's go upstairs—"

Fisher, who had already arrived at the front desk, turned his head to look at Zheng Jianguo, who quickly followed and nodded at the laboratory members who were standing at the front station, but soon found that he had forgotten the names of these two.

"This is Jack, this is Ted, they joined the lab after you left-"

Fisher's voice sounded beside him, and Zheng Jianguo smiled at the two freckled faces: "Hey, I'm Zheng Jianguo-"

"Well, Zheng, we know you, the professor has said your findings many times—"

Jack was a little shorter with brown hair, and Ted next to him had reached for his bag, "Zheng, I'll take it for you." ”

"No, thank you!"

Zheng Jianguo smiled and refused directly, and the two did not continue to speak and followed Fisher to their respective rooms, looking out the window at the sunny but constantly loud horn sound, he also realized the difference between Boston and Manhattan: "The difference in temperature is also a bit too big-"

"Hey, Zheng, do you want to go down and take a walk?"

Jack's voice came from the open door, Zheng Jianguo turned his head to look at him with hidden anticipation before he wanted to speak, when he heard two loud noises outside the open window: "Ping-ping-ping-"

"Shet!"

Zheng Jianguo turned his head to look, Jack had already quickly closed the door and looked around on the balcony, and said in a hurried voice: "This is a gunshot, I didn't expect it to be so chaotic here-"

"Bang bang—"

Before Jack's voice could disappear, there were two slams on the closed door, and Ted's voice followed the person into the room: "Zheng, are you alright, Jack - don't stand on the balcony, be careful of being shot in the head." ”

"We're fine, what, you scared me. ”

Jack's face changed slightly and he quarreled, and Ted pointed to the balcony and said, "I have a friend who stood up after hearing a gunshot on the balcony and was knocked out of his ear by a stray bullet, do you want to taste stray bullets too?"

"Okay, okay, I'll listen to you now. ”

After Jack's face changed greatly, he looked at Zheng Jianguo, who seemed to be okay next to him, and couldn't help but speak: "Zheng, you seem to be used to the sound of gunshots?"

"It's not that I'm used to gunshots, it's that I've been used to shootings since I came to the United States, and it seems like a daily occurrence from the report. ”

Zheng Jianguo almost said that the free United States shoots every day, but fortunately, he knows that this is also in Mandarin to say more rhyming, if it is changed to English, it will be different, but this gunshot still reminded him: "It seems that you have to reduce the number of times you go out in the future - you don't go around." ”

"This thing is a sudden thing, and the probability looks like the numbers are quite different, but in reality, there are only yes and no results. ”

Jack subconsciously spoke, but fortunately, he was also frightened by Ted's statement before, and finally changed his words: "Of course, probability is probability-"

"Okay, let's go, I'm going to rest for a while, call me when it's time to eat. ”

Zheng Jianguo opened his mouth to pick up people, he could see Ted's caution and Jack's big swagger in this short time together, but his time was precious, and the papers in his purse did not increase but decreased two more, so he began to review the papers after the people left.

It wasn't until the next morning that Fisher came over for breakfast, Zheng Jianguo accompanied him to the building not far away to report his name, and under the guidance of the waiter, he went to a conference room, and found that he was paying attention to the man in black at the door, and Fisher next to him said: "There is Brody, the patron of our society, and Mr. Governor of Pennsylvania, this should be his bodyguard——"

"The governor has something to do, and I'm the head of security for this meeting—"

The tall man in a black suit and black leather shoes with black sunglasses answered, and his eyes wandered over the two of them and made a gesture of invitation: "This meeting is a closed-door meeting, you can only participate if you receive an invitation, now please report your name." ”

Raising a somewhat pale eyebrow, Fisher spoke: "I'm Fisher of Harvard University, and he is Zheng Jianguo of Harvard University—"

The dim lighting, the gorgeous tapestry, and the buzzing decibels in the conference room of 100 people are not as loud as the sound of their own air conditioners, this is Zheng Jianguo's most intuitive feeling after entering the conference room, and the second feeling is that there are a little too many bright brains in this room.

"Fisher, welcome, this young man is Zheng~"

A slightly gentle deep voice pulled Zheng Jianguo's attention back, and Fisher's voice followed: "Since you recognize it, then I won't introduce it to you, Zheng, this is Lancelot Naggs, the president of the British Physical Society—"

"Mr. Lancelot, it's a pleasure to meet you—"

Seeing that a bare head was reflecting a not-so-bright light, Zheng Jianguo spoke with a smile on his face, and saw the chairman in a neat three-piece suit turn his head to look at Fisher: "Fisher, did you tell Zheng about my master's status?"

"No, Lancelot, how can I speak out about your shortcomings, especially in front of young people, well, I'm telling you, the young people now are not what we were then, you don't know what Zheng brought today-"

Fisher ignored the smell of gunpowder in the other party's words, but shook his head and smiled at Zheng Jianguo with approval on his face, just when the latter thought he was talking to himself, Fisher turned his head to look at Lancelot: "He proposed that the atomic-level graphite layer may not be an absolute two-dimensional plane structure, but with a certain curvature to allow the atomic-level graphite layer to exist at room temperature——"

"Really, oh, Fisher, whoever has a mentor like you is called unlucky, this is the content of Zheng's speech, but you said it like that. ”

Lancelot's small eyes widened instantly, and he saw Zheng Jianguo looking at Fisher with a stunned face, even if he guessed the possibility that this was extremely close to the truth: "Zheng, now your speech can be saved, and our small-scale meeting will be discussed instead of a meeting to make a report - you don't have to be sad." ”

"Those opportunities are given to those who need them, but you don't need those things now—"

When Fisher and Lancelot were talking, a few people with different looks and curious expressions came to the side, and their voices were not high or low and muttered something to Zheng Jianguo in private, and then someone answered: "Zheng, is there a result?"

"No, he hasn't started yet, well, he was busy preparing for his medical school graduation exams, and now he has signed an agreement with Massachusetts General Hospital, so we can rest if we have ideas-"

Fisher's voice spread, and the discussion suddenly became more than a dozen decibels, and even Lancelot looked at Zheng Jianguo with suspicious eyes, looking incredulous: "Zheng, did you pass the graduation exam?"

"Yes, Mr. Lancelot, now wait for the graduation ceremony to get your certificate. ”

Zheng Jianguo's posture was a little lower, and his words still carried the restraint of the students when they saw the professors, which Lancelot discovered, and Fisher also knew it, and the people next to him also thought that this was the real him, so they began to discuss it word by word.

Knowing that he didn't have the opportunity to appear on stage, Zheng Jianguo put the mask on his face that he hadn't taken out for a long time, and followed Fisher to participate in the three-day meeting and discussion.

It's not that you're young and unqualified, it's that everyone does it – physicists don't have business cards!

Because of the shooting case on the first day of coming, Zheng Jianguo squatted on the bed holding coffee and reading papers in addition to the venue and hotel in the past three days, so he didn't feel that time was slow, but when he left the room and rushed to the airport on the last day, he confirmed that the name on his head was still too small, and Dongwang didn't recognize him.

Of course, the biggest possibility is that you recognize yourself, but you don't feel like there's any value in making friends?

"Hi, Zheng—"

Zheng Jianguo, who was following Fisher into the departure hall, heard a call, but before he could look and open his mouth to respond, there was already a tall blonde next to him who lifted the sunglasses on the bridge of her nose, and a smile appeared on her delicate melon seed face: "Hello." ”

"Hi Silk, hello—"

The familiar face came into view, Zheng Jianguo's eyes widened instantly, he looked up and down at the girl who was about the same height as himself, and couldn't help but smile and said, "Well, you seem to have grown taller again-"

"Why, do you think that's bad?"

Camille Xiaosi looked Zheng Jianguo up and down, just as the surprise on this person's face told that she didn't expect to see herself, she also didn't expect to meet Zheng Jianguo here, but after her eyes fell on the two young people who were also stunned next to her, she also fell on the leather bag in Zheng Jianguo's hand, and quickly changed her words: "The movie "Youth Coral Island" starring me will be released next month, can you come over to attend the premiere?"

"This-"

Zheng Jianguo subconsciously wanted to refuse, but his eyes fell on the cheeks that exuded a youthful breath like flowers and jade, especially when he met the eyes that flashed with blue waves, he felt that it would be too cruel to refuse, although this girl was about the same height as himself, but she was only 15 years old?

This thought flashed through his mind, Zheng Jianguo tilted his head and put down his handbag, took out a small notebook from his pocket and wrote two sets of numbers on it, then tore it open and handed it over: "Okay, this is my contact information, phone and paging, if the phone can't get through, just leave me a message on the page." ”

"Oh, okay, then—"

Camille Xiaosi took the piece of paper and looked at it, and before she could finish speaking, a voice suddenly came from the side: "Hani, you are with-"

With the voice, a tall woman who was also wearing a hat and sunglasses walked over, but when Zheng Jianguo's face was imprinted in her eyes, the woman swallowed back the words behind, nodded at Zheng Jianguo with a slight change in her face, and then turned her head to Camille Xiaosi's ear and said, "Put on your glasses, hurry up-"

"Okay!"

Camille Xiaosi shrank her neck at Zheng Jianguo next to her, revealing a naughty and delicate appearance and put on sunglasses, the latter couldn't help but smile when she was infected, and then saw the woman's eyes flashing sharply, so she heard Camille Xiaosi say in a coquettish voice: "Hi, Zheng, this is my mother, have you said a lot of bad things about her~"

"Ahem, I'm sorry, ma'am, I used to be ignorant-"

Seeing that Camille Xiaosi was untying the knot between herself and her mother, Zheng Jianguo subconsciously apologized, but a thought quickly appeared in his heart: "Camille Xiaosi is still quite smart, and she knows how to use these little tricks to resolve the embarrassment that may arise——"

"Hey Zheng, it's time for us to check in. ”

Fisher's voice came from afar, and Zheng Jianguo said to Camille Xiaosi: "Hey, I should go, let's talk next time, how about it?"

"Camille, it's time for us to check the ticket too~"

The woman said and glanced at Camille Xiaosi, who smiled at Zheng Jianguo: "That, let's check the ticket together-"

"Uh, okay!"

Nodding at the woman, Zheng Jianguo followed the mother and daughter to the ticket gate, and when he said that this time it would not be so coincidental, he also heard that the mother and daughter were not going to Boston, but to Miami, Florida. ”

"Well, okay, I'll do my best to arrange it!"

Zheng Jianguo blinked and quickly responded, but quickly remembered the message that Ullica had left on the phone, and also remembered Zhao Liangliang's joke, and couldn't help laughing: "Of course, if you can give me a few signed photos, it will definitely play an unexpected role when I bribe those colleagues——"
