Into Unscientific

Chapter 674 An encounter between two gods

 A few days later.

UC Berkeley.

 Visitor reception center.

　　　　　　　　　　　　　　　　　　　　　　　　　 institutions

Hearing the cheerful sound of the alarm clock beside the bed, Li Jingjun, who was still a little sleepy, suddenly opened his eyes.

He first reached out and pressed the button on the alarm clock. When silence returned to the room, he moved his body and leaned on the cushion at the head of the bed.

Li Jingjun, who just turned fifty this year, has never had very good sleep quality. After waking up every day, he feels dazed for a long time.

However, after noticing the time on the calendar next to the alarm clock, Li Jingjun's body suddenly shook slightly, and he suddenly woke up.

At this moment, a time is clearly displayed on the calendar:

 Wednesday, October 28, 2018.

That is.

 The day when the journal "PhysicalReviewLetters" is released!

So Li Jingjun quickly got out of bed, put on his clothes, washed up and left the room.

Those who have served as professors at the University of California, Berkeley, should all know this.

Although the visitor reception hall at Berkeley has the word "reception house" on it, it is actually a very high-end hotel - the kind with a revolving door.

To know.

At this time, revolving doors are not a popular product of later generations. Although this thing was invented as early as the 19th century, early revolving doors did not have infrared sensing devices.

  In other words, that type of revolving door will just keep rotating and it is impossible to tell whether there are guests coming in or out.

The revolving door of the Visitor Hostel at Berkeley is equipped with microwave radar and infrared sensors. It is one of the landmark buildings built with heavy investment by Berkeley.

At the same time, because Berkeley is one of the largest gathering places for Chinese in the United States, the school also thoughtfully provided Chinese food and chopsticks—although there were only a few dishes such as millet porridge and fried dough sticks, it was considered a certain level of care.

For example, when Li Jingjun was getting his meal, he saw a few third brothers complaining about the lack of curry and chickpeas, and they looked a little unconvinced.

Of course.

If Xu Yun could be present at this time, his feelings would probably be deeper.

after all

　　In the later life when he traveled back in time, the catering at the visitor reception hall at the Berkeley campus was completely the opposite of what it is now. In addition to European and American breakfast, only Indian food was provided, and Chinese food was no longer available.

This can also reflect the ability of scientists studying in the United States during the two periods. Only if your ability is high enough, others will respect you.

Then Li Jingjun made a bowl of millet porridge, an egg and a plate of peanuts, and chose a relatively secluded place to sit down and eat.

 It turned out that I just ate it a while ago.

Li Jingjun heard a voice in his ears:

 “Brother Jingjun, good morning.”

Li Jingjun turned his head and found Xiao Yang standing next to him holding a dinner plate, looking like he was ready to find a place to have breakfast.

Upon seeing this, Li Jingjun quickly put down his chopsticks, picked up the tablecloth and wiped his hands:

 “Xiao Yang, are you awake too?”

Li Jingjun and Xiao Yang currently do not work at the Berkeley campus, so they were temporarily arranged by Chen Shengshen to the reception center a few days ago.

 As for Chen Shengshen, he lives in the school’s staff community, which is more than 20 minutes’ drive away.

 Hear what Li Jingjun said.

Xiao Yang nodded politely:

 “Well, I just woke up.”

Li Jingjun asked him with a smile as he asked him to sit down:

“Xiao Yang, how are you? Did you sleep well yesterday?”

Hearing this, Xiao Yang showed a wry smile and tapped his dark circles with his index finger:

“Brother Jingjun, look at the dark circles under my eyes, they are almost as big as Gungun’s. Do you think I can sleep well?”

Li Jingjun laughed twice.

 Today is the day when "Physical Review Letters" is published. With the letter from the capital in front of me, it is impossible not to be nervous.

 He is actually similar to Xiao Yang, except that he is older than Xiao Yang, so the fatigue is not so obvious on his face.

Then Li Jingjun picked up a peanut, put it in his mouth, chewed it, and asked Xiao Yang:

"Xiao Yang, what time does "Physical Review Letters" usually publish today?"

Xiao Yang thought for a while and explained:

“The rule is that it is published at 12 noon on Wednesday, but this usually refers to retail time.”

“For institutions like Berkeley that order back journals, the journals will often be delivered to the journal mailroom earlier. Normally, you may receive them at nine or ten.”

Li Jingjun nodded thoughtfully.

Although he is a top expert in biochemistry, most of the related fields are bimonthly publications. Weekly publications with more accurate time really lack sufficient understanding and experience.

 He thought he and Xiao Yang were going to a newsstand today to spend money on papers, and even prepared some change.

Of course.

He would definitely not talk about such an embarrassing thing to Xiao Yang, and soon started eating porridge normally again.

 More than ten minutes later.

Xiao Yang glanced at the empty plates in front of the two of them and said proactively:

“Brother Jingjun, how about we set off now?”

Li Jingjun picked up a piece of paper and wiped the corners of his mouth:

"no problem."

The two of them quickly arrived at the lobby of the guest house, which is also the entrance to the revolving door, and found the driver Chen Shengshen had arranged for them in advance. The car quickly left the guest house.

 Fifteen minutes later.

　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　—

 The car stopped steadily outside a quiet three-story building.

 Li Jingjun and Xiao Yang got out of the car one after another.

Before the two of them could stand firmly on their feet, Chen Shengshen's voice came from the small building:

 “Brother Jingjun! Xiao Yang!”

I saw Chen Shengshen walking out of the small building with long strides. He didn't stop until he was beside the two of them:

 “How are you, have you eaten?”

Li Jingjun and Xiao Yang looked at each other and smiled. It was another standard Chinese greeting.

Then the three of them briefly exchanged greetings, and Li Jingjun couldn't help but look inside the building and asked:

 “Brother Shengshen, has the new issue arrived?”

Chen Shengshen nodded, took someone's hand and walked into the building:

“Well, a batch of new journals has just arrived, but there are several hundred of them, and the employees in the mailroom are still sorting them.”

“But I have already told a few of them that if the journal "Physical Review Letters" is sorted, give it to me first."

  Berkeley, as a core branch of the University of California, basically has full-funded subscriptions for papers.

 Although most papers these days are published monthly or bimonthly, there are too many journals that cannot be maintained.

 In addition, some journals require a large number of copies to be ordered at one time and distributed to various colleges, so the mailroom has to handle hundreds or even more journals and magazines every day.

Most of these journals are packaged and processed through the San Francisco Bay Area, and then violently sorted all the way to the school like express delivery.

Of course. If you really want to know the journals released that day as soon as possible, you can also ask someone to send them by fax over long distances. However, this operation usually cannot be carried out until the official publication, and the time may not be faster than sorting. How many.

When the three of them walked into the building where the mailroom was located, there were also seven or eight men and women of different ages standing in the aisle next to them.

“These are also lecturers or professors who come to pick up journals.”

As Chen Shengshen walked, he used [Chinese encryption] to quietly introduce the identities of other people:

“The long-haired lady is called Wendy, an Italian music teacher. She ignored me after I made a pig’s blood pizza last week.”

“The old man in white clothes is called Ben Yangming, and you can tell he’s from Gaul just by looking at his clothes.”

 After a while.

Chen Shengshen led the two of them to a foreign man in the corner, and said to Li Jingjun and Xiao Yang in English:

“Brother Jing Jun, Xiao Yang, let me introduce to you, this is Mr. Steven Weinberg.”

“Steven is a top student who graduated from Cornell University. He worked as a postdoctoral fellow at the University of California, Berkeley for two years, and just became a lecturer at Berkeley last year.”

“Steven, these two are my compatriots, Professor Li Jingjun and Professor Yang Zhenning.”

Weinberg was reading a book quietly. Hearing this, he was stunned for two seconds, and then looked at Xiao Yang with great joy:

 “Mr. Yang, it’s really you! I’ve admired you for a long time!”

Xiao Yang shook hands with him cheerfully, his expression not too harsh but not enthusiastic either.

After all, he has seen such scenes too many times after winning the Nobel Prize, and has developed a basic sense of normalcy.

  Steven Weinberg.

Neither Xiao Yang nor Li Jingjun have heard of this name. Judging from his age, he is estimated to be close to thirty. He has just become a lecturer at Berkeley. The probability of making dazzling achievements in the future is honestly not high.

 After both parties separate their hands.

Weinberg did not stop thinking about communication, but took out a pamphlet and a pen from his body:

“Mr. Yang, can I talk to you about some issues about symmetry?”

Xiao Yang blinked:

 “Symmetry?”

Weinberg nodded vigorously:

“Yes, especially some problems in the structural application of SU(2)×SU(2).”

 This time.

Xiao Yang finally looked at Weinberg with some curiosity.

 It is well known.

Although Xiao Yang and Xiao Li jointly won the Nobel Prize, the result they won the Nobel Prize for was the law of parity nonconservation in weak interactions.

 So when most people want to chat or establish a relationship with Xiao Yang, they usually talk about parity non-conservation.

 But Weinberg was different.

The first thing he started talking about was the structural application of SU(2)×SU(2), which involves the concept of another framework.

 So Xiao Yang soon became interested and asked Weinberg:

“Mr. Steve, have you also researched the wheel-riding changes of SU(2)?”

Weinberg sighed excitedly again. He didn’t expect that he would meet the person involved in the problem he was thinking about last week:

“I have been studying electroweak symmetry breaking some time ago, and I found that according to your Yang-Mills framework calculation, the scalar part of the Lagrange quantity will have two more strange charging ratios.”

“Later I followed the Gell-Mann-Nishijima relationship Y=2 (QT3) in hadrons, where Y is hypercharge instead of weakhypercharge, and T3 is also the isospin of flavorsymmetrySU(2) instead of weakospin, but something still seems wrong.”

Hearing this, Xiao Yang said oh and stretched out his hand towards Weinberg:

"May I see it?"

Weinberg quickly handed the small book to Xiao Yang.

Xiao Yang found a more remote location and sat down, with his legs crossed and he began to analyze.

 When Chen Shengshen and Li Jing both saw this, a little surprise flashed in their eyes.

As Xiao Yang's old friend, both Chen Shengshen and Li Jingjun have known Xiao Yang for more than ten years, and they know their good friend's character well.

To be honest, it’s not like they haven’t seen Xiao Yang being serious, but at those times the people sitting across from Xiao Yang were basically the top physics guys in Europe and the United States.

This young man was able to arouse Xiao Yang's interest to this extent with just a few words. He was very capable.

ˆ “.”

that's all.

 A few minutes passed.

Xiao Yang just put down his pen again, and a trace of solemnity flashed in his eyes:

“Strange. There are indeed two more charging ratios.”

“If we use the conventional method, the Yukawa effect in the Rascal mass will offset them, but using the framework calculation derived by Teacher Mills and I, it is extremely obvious. There should be something here.”

Weinberg nodded in agreement.

 This is a non-universal phenomenon, so there must be something undiscovered in some theoretical corner.

 The tricky part right now is how to determine the "identity" of this thing and how to clarify its physical meaning.

 At the same time, compared to Weinberg, Xiao Yang had another premonition in his mind:

 This may be an opportunity to complete the Yang-Mills framework!

 There are problems with the first version of the Yang-Mills framework derived by him and Mills. This is something that the entire physics community is well aware of.

  The original purpose of Xiao Yang and Mills to construct this framework was just to supplement a normative theory, which is a natural mathematical extension.

 Gauge theory existed in electrodynamics as early as the 19th century, but people did not pay enough attention to it and it was just regarded as a mathematical technique.

So Xiao Yang himself has actually been trying to optimize this framework over the years. For example, last year he removed the cumbersome degrees of freedom of field variables, introduced the D'Alembert operator at the beginning of this year, etc.

 The issue raised by Weinberg may be another opportunity for optimization.

Think of this.

Xiao Yang slowly closed the notebook in front of him and went through the contents he had memorized in his mind before returning the notebook to Weinberg:

“Mr. Steve, the question you raised is very interesting. If possible, can you give me your contact information?”

Weinberg was stunned for two seconds, and then his eyes burst into light of excitement.

Mr. Yang actually asked for his contact information?

　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　—

 Then Weinberg swallowed hard, turned the notebook to the last blank page, and quickly wrote a few lines:

“Mr. Yang, this is my mailing address. Below are my telegram and fax numbers.”

Xiao Yang took the piece of paper with a smile again, folded it in half and put it in his inner breast pocket.

Then he opened his mouth, as if he wanted to say something:

"So."

 As a result, the words did not come out.

The door of a room not far away was opened with a bang, and a black woman with curly hair poked her head out:

 Hello, gentlemen, "PhysicalReviewLetters" has been found!"

Note:

The body temperature is 36.7. The current problem is still severe pain in the mouth and low back pain. I will try to complete the adjustment within three days.
