"Hey, isn't this Academician Lin? He's a rare visitor."
At the door of a house, an old man opened the door and looked at the young man standing outside. A kind smile suddenly appeared on his face and he welcomed him in.
After hearing the old man's question, the young man suddenly looked helpless and said, "Mr. Yang, please don't call me Academician Lin. Just call me by my name."
The young man is naturally Lin Xiao, and the old man is Yang Zhenning.
"Hahaha, it's just a name. It doesn't matter if you shout it. What's more, I should shout it too. For such a young academician, it would be bad if he doesn't shout it anymore."
Mr. Yang said with a smile, and after closing the door, he led Lin Xiao into the living room.
Mr. Yang was pleasantly surprised by Lin Xiao's arrival, but he was not surprised, because Lin Xiao would come to see him occasionally, maybe once a month when he was free, and maybe once every few months when he was busy.
Although the Lantern Festival has just passed, it is still the first month of the year after all, so it is certainly not surprising that Lin Xiao came to see him.
"Here, drink a glass of water."
"Oh, thank you."
Lin Xiao took the water and thanked her.
Although there is a nanny at home, Mr. Yang poured this glass of water for him personally. Of course, just pouring water is just a master's way, but for Mr. Yang's physical condition, which is over 100 years old, it is indeed a bit rare.
.
Then, Mr. Yang stuffed him with some more fruits and said with a smile: "Here, these strawberries are quite sweet. I just picked them yesterday. Let's try them."
"Okay, okay, hey, that's all."
Lin Xiao felt dumbfounded, and felt a little emotional in her heart.
This scene is just like how his grandparents always give him food and drink every time he returns to his hometown.
The old man in front of him has once been on the Nobel Prize podium and is considered to be the top scientist among all physicists in the history of the world.
But when he returns to life, he is no different from a normal old man.
"Just take it, and I'll carry another bag for you when I leave later. You haven't been to my place for a long time, and I don't know how long it will be next time."
Yang Laogong stuffed another one into Lin Xiao, then shook his head and said, "I don't know when I will never see you again."
"How could this happen..."
When Lin Xiao was about to say something like this, Mr. Yang waved his hand, interrupted him, and said: "Okay, no need to talk about these nonsense. I think you came today because you have other serious matters to see me.
Right? So you'd better just tell me and see if I, an old man, can give you some help."
Hearing what Mr. Yang said, Lin Xiao stopped being polite and said, "Mr. Yang, I really have something to ask you about, about the quality gap."
Mr. Yang was stunned for a moment: "Is there a quality gap problem?"
Probably no physicist in the world is as familiar with this issue as he is.
After all, the name prefix in this question contains his surname.
As the proposer of the Yang-Mills gauge field theory, he made the greatest contribution in the process of proposing this theory. Even another Mills has admitted this to the public.
Because of this, he is also very familiar with the issue of mass gaps.
He smiled and said: "It seems that our Academician Lin has now set his sights on an ultimate problem. Good thing, good thing."
Lin Xiao said helplessly: "Mr. Yang."
Mr. Yang laughed heartily, and then finally returned to his seriousness, and said: "Okay, let's not talk anymore. Of course, there are many problems related to the quality gap, and I know a lot of things. What do you want to know?
What about aspects?"
Mr. Yang, who had regained his integrity, finally gained academic rigor.
Lin Xiao, on the other hand, said without any nonsense, "Everything."
"all?"
Mr. Yang was stunned again and showed a little surprise: "It seems that you really want to solve that problem first!"
Before, he thought that Lin Xiao just suddenly became interested. After all, when Lin Xiao came to see him before, he often asked him about some related issues, such as anecdotes from the physics community in the last century, or some academically unreasonable topics.
Things that people know.
But this time, Lin Xiao seemed to have some ideas.
"In that case...then come with me."
Mr. Yang stood up and walked towards the house.
Lin Xiao quickly followed, and soon arrived at Mr. Yang's study.
In the study, you can see scientific books everywhere, and of course there are also some common books in the study, such as the Four Great Classics, Zizhi Tongjian, and Historical Records.
However, for these two scientists engaged in natural science research, these things are not what they care about.
"Let me look for it. I remember that I have some of my old manuscripts here."
"Although the problem of quality gap could not be solved at the beginning, I have discussed it with many people and these manuscripts have been preserved..."
"Well, I found it. It's this box, up there."
Lin Xiao raised his head and took a look, and saw a box on the top of the bookshelf.
He said: "I'll get it."
"Come on." Mr. Yang stepped aside and sighed: "People are no longer useful when they are old. Standing is too tiring."
Lin Xiao brought a chair over and took down the box.
There was dust on the box. It seemed that it had been there for a while. After it was wiped clean, its true appearance was clearly revealed.
"That's it. Hey, I still remember these things clearly."
Mr. Yang looked at the box Lin Xiao carried down and said with a smile.
There was a coded lock on the box, and Mr. Yang told the code without hesitation.
After opening the box, there was a thick stack of straw paper inside. It could be seen that these papers were originally white, but now they have turned yellow.
Although the ink on the handwriting on it has spread a little, you can still see what is written on it.
"Well, this is part of what I have preserved. The other part is in the Qinghua Library. After I returned to China, I donated many manuscripts to them. You should be able to find it there."
When Lin Xiao looked at so many pieces of paper, he couldn't help but marvel that there were so many. If the part donated to Qinghua was included, there would probably be even more.
Of course, he also had many manuscripts of his own, and they are all preserved.
Maybe one day, he will donate his manuscripts to a library, and then they can be viewed by future generations?
"Thank you, Mr. Yang."
"What's there to thank you for?" Mr. Yang waved his hand: "I think the meaning of these manuscripts is to wait until one day they are handed over to another person, and then this person will no longer need to care about the original owner.
Find out the overlooked knowledge points between the lines."
"Of course, this is also the meaning of the existence of knowledge. It can be passed on continuously and then bloom into the final glory in the hands of others."
"As an old man like me, I can no longer create these things on paper, so I have to take on the responsibility of handing these things over to you."
Mr. Yang gently picked up the first piece of paper, as if he saw himself when he was young, and then gently put it back and said: "So, I will give all these things to you, so that they will not be used after I leave."
It would be a pity if my family members threw it away as worthless things."
Lin Xiao nodded: "I understand, I will keep it well."
Then he smiled: "Of course, maybe one day in the future, I will also take these manuscripts of yours and hand them over to others together with my manuscripts."
Mr. Yang was stunned for a moment, then smiled and said: "Wouldn't it be better? My knowledge has been passed on to two people, and your knowledge has also begun to be passed on. I wonder if it can be passed on for much longer."
Lin Xiao laughed: "That would be the best."
"Yes." Mr. Yang nodded, turned around and walked out of the study, and asked at the same time: "Are you staying for dinner today?"
"Let's eat." Lin Xiao did not refuse.
"Okay." Mr. Yang's smile became even bigger.
…
After having a meal at Yang's home, Lin Xiao embarked on the process of collecting information again, that is, going to Qinghua's library to borrow the materials donated by Mr. Yang.
These things are necessary for the problem he wants to solve.
If he wants to solve the mass gap problem of the Yang-Mills gauge field, he certainly needs to look at what previous people have thought about it.
In this way, we can better serve him in solving these problems in the future.
In this way, I arrived at Qinghua University. In fact, it is not far from Mr. Yang's house, because Mr. Yang lives in the master's residence specially built for him by Qinghua University, and the two places are not far apart.
When Lin Xiao came over, he didn't attract too many people's attention. After all, he didn't want to attract anyone's attention. However, after arriving at the Qinghua Library, renting those Yang Lao's manuscripts required a series of procedures, which made
He had no choice but to make a phone call.
So after spending a lot of effort, he finally borrowed Mr. Yang's manuscripts on the Yang-Mills gauge field theory and the mass gap problem.
The next step is to find out from these manuscripts those things that have been ignored but actually contain hidden value.
