Into Unscientific

A few days later.

UC Berkeley.

Visitor reception.

Tick ​​bell——

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

snap——

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 50 this year, has never had very good sleep quality. After waking up every day, he was confused 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, xxx.

That is.

The day the journal Physical Review Letters is released!

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

Students 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 "Hospitality" 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 common 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 guest house at Berkeley is equipped with microwave radar and infrared sensors. It is one of the landmark buildings built by Berkeley with a lot of money.

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 picking up his meal, he saw a few third brothers complaining about the lack of curry and chickpeas, looking quite 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 University of Berkeley 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 will others respect you.

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

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

A voice rang in Li Jingjun's 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 Berkeley, 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.

Hearing Li Jingjun’s words.

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?"

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

"Brother Jingjun, look at the dark circles under my eyes, which 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 hours."

"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 magazines with more accurate time really lack sufficient understanding and experience.

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

Of course.

He would definitely not talk about such embarrassing things 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 them and said proactively:

"Brother Jingjun, how about we leave now?"

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

"no problem."

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

Fifteen minutes later.

Stab——

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's it going? Have you eaten?"

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

Afterwards, 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 new batch of journals has just arrived, but there are hundreds of them. The employees in the mailroom are still sorting them."

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

As a core branch of the University of California, Berkeley is basically a full-funded subscription for papers.

Although most of the papers these days are published monthly or bimonthly, there are too many journals to support them after they are completed.

In addition, some journals require a large number of copies to be distributed to various colleges at one time, 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 to the school like express delivery.

Of course.

If you really want to know the journals published 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 collect journals."

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

"The lady with long hair is called Wendy, an Italian music teacher. She stopped talking to me after I made a pig's blood pizza last week."

"The old man in white clothes is called Ban Yangming. You can tell by his clothes that he is from Gaul."

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 Jingjun, Xiao Yang, let me introduce to you, this is Mr. Steven Weinberg."

"Steven is a top student who graduated from Cornell University. He spent two years as a postdoctoral fellow at the University of California, Berkeley, 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 happily, his expression was not 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 the two parties separated their hands.

Weinberg did not stop thinking about communicating, 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 with the structural application of SU(2)×SU(2)."

This time.

Xiao Yang finally looked at Weinberg with some curiosity.

As everyone knows.

Although Xiao Yang and Xiao Li have jointly won the Nobel Prize, the result of their Nobel Prize is the law of non-conservation of parity 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 ride changes of SU(2)?"

Weinberg hummed 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 when calculated according to your Yang-Mills framework, the scalar part of the Lagrange quantity will have two more strange charging ratios."

"Later I followed the Gell-Mann-Nishishima relationship Y=2 (QT3) in hadrons, where Y is hypercharge instead of weak hypercharge, and T3 is also the isospin of flavor symmetry SU(2) instead of weak isospin, but it seems There’s still something wrong.”

When Xiao Yang heard this, he 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 lifelong 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 bosses 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 skillful.

"."

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 conventional methods, the Yukawa effect in the Rascal mass will cancel them out, but using the framework calculations deduced by Mr. 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.

But 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 heart:

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

There were problems with the first version of the Yang-Mills framework that he and Mills derived, and this was something that was well known throughout the physics community.

The original purpose of Xiao Yang and Mills in building this framework was just to supplement a gauge 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 question raised by Weinberg may be another opportunity for optimization.

Think of this.

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

"Mr. Steve, the question you raised is very informative. If possible, can you give me your contact information?"

Weinberg was stunned for two seconds, and then his eyes lit up with excitement.

Mr. Yang actually asked for his contact information?

Gulu——

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, no words came out.

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

"Hello, gentlemen, "Physical Review Letters" has been found!"

Note:

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