you come from the sky

"Bian Yu, Dr. Bian, I need you, I need you to come with me."

The words "I need you" came out of Fang Haochen's mouth so bluntly, it seemed that Bian Yu was very surprised. He, who has always been eloquent and frivolous, stared at Fang Haochen and was speechless for a while.

But Bian Yu is a veteran in the field of love, he just lowered his head briefly, and soon put on the mask of a swinger, as if mocking, and asked: "Director Fang, are you drunk?"

After Bian Yu asked, he was quite surprised to see that Fang Haochen didn't refute: "You really can drink so much..."

Drunk, indeed a little bit, Fang Haochen knew that he was not good at drinking, so he never drank it. He originally thought that the red juice in Bian Yu's bottle was just like sugar water, but he didn't expect that after half a glass, the alcohol immediately made his whole body hot. His tongue was numb, but he became more courageous.

When Bian Yu supported him, he didn't shake off like an electric shock. Fang Haochen only felt that his whole body was limp, and he put all his weight on Bian Yu. Bian Yu had nothing to do with him, he could only hug him and sit. to the bed.

It was a very strange touch.

Fang Haochen thought in a daze that he had never experienced it before.In his memory, his mother had never hugged him. Later, when he came to his aunt's house, the whole family of his aunt, especially Yuan Youbing, who was three years younger than him, was indeed very kind to him, but Yuan Youbing's concern was always a little reserved and jerky. Hitting his arm was considered the limit.

Is that what a hug feels like?

It was warm and wonderful, and any kind of calculus or tensor analysis could not deduce the slightest change in his chest.

Bian Yu put Fang Haochen flat on the bed, pulled a stool over and sat down, looking at Fang Haochen's appearance, he felt a little apologetic: "Now it's like I'm bullying you."

"You're embarrassing me." Fang Haochen closed his eyes and frowned.

Bian Yu laughed: "Why am I embarrassing you? If I don't go to 201 with you, will I embarrass you?"

Fang Haochen was so dazzled by the lights on the ceiling that he couldn't open his eyes, and complained with a smell of alcohol: "The lights are too bright, turn them off."

Bian Yu stared at Fang Haochen for a few seconds, as usual, he would have teased Fang Haochen a few words, but now he simply replied: "Okay."

Then he stood up and turned off all the lights in the room, leaving only the moonlight outside to shine on the dormitory. In the darkness, there were only Bian Yu and Fang Haochen.

Bian Yu looked at Fang Haochen who was lying on his bed. After he was drunk, his cheeks flushed a little due to the effect of alcohol, his eyes were closed and his brows were slightly frowned, but he seemed a little more humane.

"Dr. Bian—"

"Call me Bian Yu." Bian Yu interrupted.

Fang Haochen still closed his eyes, and hummed: "Bian Yu."

Hearing his name from Fang Haochen's mouth, Bian Yu felt a little strange, he smiled, and asked like a good friend: "Are you still drunk, Haochen?"

Fang Haochen immediately became alert: "Call me Director Fang."

Then he added: "I'm drunk but my mind is still working."

Bian Yu sighed softly: "Okay." He was tolerant to Fang Haochen, not only did not drive away the guests, but also asked, "Director Fang, what do you want to order?"

Fang Haochen was also polite: "Well, tell me about yourself."

Bian Yu's eyelashes moved slightly, and his eyes looked elsewhere: "What can I say?"

Fang Haochen thought for a while: "Tell me about your experience, studying abroad and returning to China."

Bian Yu asked: "Director Fang, are you asking me this to get to know me?"

"Of course I want to get to know you."

Bian Yu chuckled and wanted to light a cigarette, but looked at Fang Haochen and put it away again. He leaned back on the chair, "My story is nothing to tell, I am just an ordinary person who studied abroad and wants to come back to build a country That's all."

Fang Haochen asked, "Why do you want to come back? The conditions in China are so difficult. People like you can get much more abroad than here, right?"

"The motherland is poor and weak, it can only show that the children are incompetent."

When Bian Yu said this, looking at the moonlight all over the place, Fang Haochen suddenly remembered the article "Moonlight in the Lotus Pond", and Mr. Zhu Ziqing who would rather starve to death than receive relief food from the United States.

Fang Haochen sat up and looked at Bian Yu seriously for the first time.For the first time, what he saw was not those exquisite calculations behind Bian Yu, but Bian Yu, an ordinary but not ordinary person.

How amazing.

Bian Yu, if you don't look at him, you will feel that his every move is extremely frivolous; but if you look at him carefully, all his words and deeds will be like Huang Meitian's The rain is knocking on the door of your heart one after another, jingling non-stop.

"Let me tell you about me, too."

Fang Haochen looked at the full moon outside the window, and the moon was filled with soft silvery light, which reminded him of the "Aurora" that floated in the mountains and forests more than 20 years ago, which he will never forget.

"201 was established 25 years ago, and my mother was the first batch of researchers. When they found my mother for the first time 25 years ago, my mother asked me a question." Fang Haochen glanced at the side Yu, he listened very carefully, as if he was very interested in Fang Haochen's past, "She asked me, 'What did the fish's eyes see?'"

This memory had been dormant in Fang Haochen's heart for a long time, until one night after returning to 201, it suddenly fell into Fang Haochen's palm like a dexterous elf without warning.

"I was fiddling with the pool at that time, and the leaves of the vegetables I threw in were also rising and falling with the water. I replied to my mother, 'the fish see the leaves moving'."

"Fish cannot see water," Fang Haochen said, "so they will think that some kind of force causes the vegetable leaves to move regularly or irregularly. If there is Newton in the fish, he may also write down an exquisite formula to calculate The law of leaf movement, if there is a heavy rain one day, maybe a Heisenberg will come out of the fish, adding a hat to classical mechanics, and then he will say that observation determines the state of the vegetable leaf, neither the previous state nor the future state The state is only a momentary state."

Fang Haochen sighed almost imperceptibly at this point: "But if the fish were us, they would know that the water is only moving with the leaves. So, what about us? Those orderly or disorderly movements, when we jump out Will you find that they all have a unified set of theories?"

"Electromagnetic force, gravity, strong nuclear force, and weak nuclear force still do not have a complete mathematical description. But I believe that as long as we find a unified field, we will be able to jump out of our world like a fish and see more high-level universe."

Bian Yu looked at Fang Haochen in surprise, as if he was surprised by Fang Haochen's research, and also surprised that Fang Haochen would tell him this.

"Bian Yu," Fang Haochen said, turning around and looking at Bian Yu very formally and reverently, "the development of physics is inseparable from the help of mathematics, do you think I need you? I do need you, I have never been as needy as I am." You need anyone just as much. I hope you can go to 201 with me, as long as you go to 201, you can make any request you want, and I can give you anything you want.”

"Our research is not limited to one country. If successful, it will be the most colorful stroke in the entire history of mankind."

No, it may not be appropriate to talk about human history. Fang Haochen believes that if their research is successful, then the small blue planet on the spiral arm of the Milky Way where they are located will burst out with unprecedented light. The universe remembers that billions of star clusters cannot hide.

This light will belong to him and Bian Yu. In the thousands of years to come, until the universe is reduced to endless darkness, their names will still be written together, transcending time, transcending space, and becoming eternity.

This is a dream that any scientist would be obsessed with and crazy about, and now this dream is placed in front of Bian Yu, as long as he is willing, the world will change because of him.

But Bian Yu was not the slightest bit excited.He turned his head and looked out of the window, as if he was looking at the other side of the sea, as if he was looking at the background color of the sky.

"I'm sorry, Director Fang," he said. This time, Bian Yu's tone was neither cynical nor perfunctory. "Your eyes are in the sky. I am different. My wish is very simple. I only hope that there will be more people in the future." One day, students returning home no longer need patriotic agitation, parents, friends, or lovers, I just hope that one day my country can become the yearning of students all over the world."

"Compared to yours, this wish is too insignificant, but on the day I return to China, I have made up my mind that I will do something practical. I know I am nothing, but such an insignificant me, Maybe one day it can also become a ladder for this country to become stronger."

Fang Haochen was a little anxious: "You can also make the country strong by going to 201! If our research is successful, how many students from all over the world will come to China because of their admiration for your name?"

"I'm sorry, Director Fang." But Bian Yu still shook his head, "Look, I still want to call you Director Fang. Thanks to the wrong love, but you and I have never been the same."

After Bian Yu finished speaking, he didn't give Fang Haochen time to refute. He stood up, walked to Fang Haochen's side, and stretched out his hand to him: "I think you're sober too, Director Fang, I'll take you back."

"No need." Fang Haochen ignored Bian Yu's hand, straightened up and got out of bed, "I'll go back by myself."

Note:

In Fang Haochen's explanation, two physicists were mentioned, Newton and Heisenberg.

Newton stands for classical mechanics, and the basic laws of classical mechanics are Newton's laws of motion or other mechanical principles related and equivalent to Newton's laws.There are two basic assumptions in classical mechanics. In layman’s terms, first, classical mechanics is applicable to low-speed motion compared with the speed of light. In the case of high-speed motion, time and length can no longer be considered irrelevant to the observer’s motion.Second, classical mechanics is applicable to macroscopic objects. In a microscopic system, all physical quantities cannot be accurately measured at the same time in principle.

Heisenberg is the main founder of quantum mechanics and a representative of the Copenhagen School. The most important achievement of Heisenberg's theory is the uncertainty principle, which was previously called the uncertainty principle. However, the uncertainty of the uncertainty principle is actually a theoretical The uncertainty in the universe is not unobservable, and it is a different aspect of quantum theory than that described by "Schrödinger's cat".
