At the beginning of April, a big event happened in the world of physics.

On April 8, Peter Higgs, a British scientist who proposed the "God particle" and Nobel laureate in physics, died at the age of 94.

In the development of physics, there are many scholars who can go down in history and influence the development of the entire field.

Beginning with Galileo, empirical physics in the history of civilization was transformed into classical physics; to Newton, a great figure who cannot be avoided in the history of physics and even the history of science; and then to Einstein, Maxwell, Planck, Boltzmann and others gradually established the 'Standard Model' based on the modern physics system.

It can be said that in the past three hundred years, physics has undergone earth-shaking changes, from macro to micro, from low speed to high speed, etc., affecting the development of the entire era and the entire civilization.

In the "Standard Model", the most difficult and extremely important "God particles" and "Higgs mechanisms" proposed by Professor Peter Higgs are the key to explaining how other particles acquire mass, and they are also the core of how the universe forms mass and matter.

It is no exaggeration to say that in the past half century, the most significant achievement in the field of theoretical physics has been the successful detection of the Higgs boson in the large strong particle collider Lhc.

It perfected the Standard Model and laid the foundation for the edifice of modern physics.

And today, what can be the most impressive physicist of the 21st century has passed away.

However, compared to the vast majority of theoretical physicists, Higgs was lucky.

At least, he witnessed the day when his theory was confirmed in his lifetime.

This is a regret that countless other physicists have never dreamed of coming true.

Many stars burned and extinguished alone, and it was much later that its light reached our eyes.

And Higgs was lucky to see the light from the star he had created with his own hands.

.......

In the office, the joy of the imminent completion of the annular super-particle collider cRhpc was washed away at this moment.

Whether it was Xu Chuan or Lin Feng, they all stared at the news on their mobile phones and were silent and did not speak.

For the physics community, this is a highly respected senior. His pioneering work has inspired thousands of scientists, and his contributions will continue to inspire generations to come.

With a long sigh, Xu Chuan put down the pen in his hand, stood up and walked out of the office.

April in Jiangnan was drizzling with a light rain, probably because the heavens were also grieving the loss of this great scholar.

Looking at the somewhat gloomy sky, Xu Chuan thought silently.

The passing of Professor Higgs touched him greatly.

If he is lucky, then he is probably the luckiest person.

After all, the opportunity to start over with memories can be said to be something that almost everyone dreams of.

It's just that Higgs's dream has come true, and he sees the star that belongs to him; And where are his stars?

Staring at the drizzling rain outside the hospital, his thoughts had drifted into the distance unconsciously.

I don't know how long it has been, but Xu Chuan, who was standing at the gate of the courtyard, heard someone shouting to him.

"Professor."

Coming back to his senses in a trance, he looked at the source of the voice, and was a little surprised that he was called out to be Tang Ran, the assistant of Nanda.

"Why are you here?"

Tang Ran took out a letter from the backpack he was carrying and handed it over: "Professor, this is a letter mailed from the University of Edinburgh in the United Kingdom."

As she spoke, she glanced at Xu Chuan, was silent for a moment and continued, "It was sent by that Peter Higgs."

She had seen the news published on the Internet that Professor Peter Higgs had passed away a few hours earlier.

Around the right time, NTU received a letter from Professor Higgs from the University of Edinburgh

letters.

Looking at the letter in Tang Ran's hand, Xu Chuan fell silent.

"I see."

Halfway, he whispered, took the letter from Tang Ran's hand, turned around and walked into the office.

Behind him, Tang Ran looked at Xu Chuan's back, opened his mouth and stopped.

Casually took the door of the office and sat on the sofa, Xu Chuan opened the envelope.

Inside the yellow envelope was a thick stack of manuscript paper, which was simply clipped together through a black folder.

And on the most surface, there are two or three thin sheets of stationery, which are placed on the most surface.

Xu Chuan reached out and picked up the letterhead, and his eyes fell on the handwriting that was not so regular.

[Hello, Professor Xu Chuan, I'm Peter Higgs. 】

[I've wanted to write you a letter for a long time, but because I've been recuperating, I haven't been able to spare any time. 】

[Although we regret that we have not met, for us scholars, it is not a big deal. 】

[I have read all the papers and results you have made in physics. Even though it takes me a long time to read, to think,]

[For an old man who is already 90 years old, I think this is not an easy thing to do, to know that the mathematical knowledge you have created and researched, even when I am young, it is very difficult to understand, let alone me today. 】

[However, I am proud to tell you that I have read and understood all of them, whether it is the xu-eyl-berry theorem, the proof of the radius of the proton and the method of using mathematical methods to calculate the most ideal search decay channel for high-energy particles, or the theory of the grand unified framework of strongly correlated electron systems. 】

[I am very touched to be able to see a young and great scholar growing vigorously in my lifetime, absorbing and creating a lot of knowledge. It's the future, and I'm looking forward to it, but I probably don't have much time to witness it......]

[Although I am sorry that I was not able to meet you, it is enough to be able to see the successors of the physics community in my lifetime. 】

[In the ancient words of Huaguo, the back waves of the Yangtze River push the front waves, and the blue is better than the blue, which is probably the most appropriate word. I also sincerely hope that you can go further on the road of academics. 】

[By the way, François Engler came to me some time ago, and he said that you were working on dark matter, the unified theory of strong electricity, gravity, and Einstein's Rosen Bridge. 】

[This makes me very emotional, I have to say, the field you are involved in and research is really too wide. And that's just part of what you're doing in physics. 】

[Such a vast field of knowledge and research directions, in my memory, I am afraid that only the Mr. Einstein I met when I was young can be compared. 】

[Getting back to the point, listen to Engler's bad old man say that in the unified theory of strong electricity, dark matter, gravity.... In these areas, you don't seem to have much direction at the moment. It just so happened that when I was young and had the energy to think about doing research in the early years, I also had some thoughts about these issues. 】

[And these things, I have asked the servant to sort them out and mail them to you with this letter.] Hope they can help you a little. 】

[Also, I have a small request.] 】

[If one day in the future, you can solve or confirm one of these problems, if you can, remember to burn a copy to me at my grave.] 】

[Maybe I can see it in heaven, maybe.] 】

【.......】

[Oh, by the way, there's one more thing I want to talk to you about too.] 】

[Regarding the-for-tat confrontation between cERN and cRhpc, to be honest, perhaps they can indeed promote the prosperity of theoretical physics and high-energy physics to a greater extent in a short period of time. 】

[But if you think about it from a long-term perspective, their-for-tat is very likely to split the relatively unified academic world today.

This is not good news. 】

[Because whether it is theoretical physics, mathematics, or other disciplines, as long as it is theoretical research, then it must not need the strength of a certain country, a certain region, or a certain organization.] What it requires is the joint efforts of the entire civilization. 】

[Maybe I saw something in the last days of my life, so I hope that in the future, if your cRhpc replaces the position of cERN, I hope that you will be able to accept the physicists from all countries in cERN.] 】

[The vast majority of them are innocent and not interested in these fights.] The end of civilization, even if it happens in the future, all I can do is pray in heaven that it will come more slowly......]

.......

A letter, Xu Chuan carefully read it word by word.

"We've met, Professor Higgs."

Looking at the letter in his hand, Xu Chuan muttered to himself, and a phantom appeared in front of him.

That was the scholar who wrote him this letter, Peter Higgs.

If Edward Witten was his mentor for two lifetimes, Professor Peter Higgs brought him a wealth of knowledge in the field of high-energy physics in the past.

Including the exploration of dark matter in his previous life, this deceased old man has also brought him some inspiration and theoretical concepts.

It can be said that in his last life, he was able to perfectly predict and discover dark matter, and Professor Higgs made a significant contribution.

"I can't guarantee the rest, but the dark matter theory, I'll definitely remember."

Staring at the letter, Xu Chuan breathed a long sigh of relief and said silently in his heart.

As long as the ring supercollider cRhpc is built, then dark matter is destined to be in his pocket.

It's just a pity that neither in his previous life nor in this life, Professor Higgs has not been able to see it come out with his own eyes.

Gently putting down the letter in his hand, Xu Chuan picked up the thick stack of manuscript paper on the table and turned the first page.

This is a handwritten theory, a reflection on the unity of the three forces of strong and weak electricity, written by Higgs himself.

Judging from Xu Chuan's understanding of Higgs, he is a very traditional and friendly person.

Higgs didn't have his first computer until the day he was eighty, but he replied to almost everyone who wrote to him.

In his early years as a professor, he had an email address

Whenever he received an email, his secretary would print out the received email, and he would reply to it one by one with paper letters. He then forwarded the reply to a colleague through his secretary to reply to the email.

And the colleague who handled the mail knew very well that the vast majority of the letters that Higgs replied to did not actually need to alarm Higgs and his old man.

But he still earnestly replied to every scholar who asked him serious questions.

This point, in fact, Xu Chuan himself could not do it.

His mailbox is handled by an assistant agent, and most of the mail will not be delivered to him.

......

Starting from the first page, Xu Chuan sat in the office for more than four hours, and it was not until the sun set that he finished reading the dozens of pages of manuscript paper.

After getting up and moving his muscles and bones, and turning his head and lumbar spine, he breathed a long sigh of relief and sat down again.

In fact, the manuscript given to him by Professor Higgs contains many theories and ideas, especially for the thinking in the field of high-energy physics, which he has read and understood in his previous life.

However, even if he has already read and thought about the theory, re-reading it again can still bring him some new gains.

For example, from the Higgs mechanism to the electroweak interaction.

It is well known that the vector boson that describes the weak interaction is ±, and the Z boson derives its mass from the Higgs mechanism.

And for this theory, the purpose

The previous theoretical description starts from the U(1) Higgs mechanism, which can be regarded as scalar electrodynamics coupled to the electromagnetic field by coupling the Lasnell quantity as a complex scalar field and the U(1) gauge field, in which the electromagnetic gauge symmetry is spontaneously broken.

In other words, it is scalar electrodynamics with spontaneous breaking electromagnetic canonical symmetry.

In this manuscript sent by Professor Higgs, he has further thought about the Higgs mechanism to electroweak interactions and strong electroweak interactions, and there are some things that have not been seen before.

For example, in the thinking of the asymptotic freedom of the strong interaction force (QCD), Higgs resets the trivial field theory and introduces part of the theory of the grand unified framework of strongly correlated electronic systems in condensed matter physics.

If it is correct, it means that the strong coupling constant decreases as the energy scaler increases, and tends to 0 at high energy, so the view that QCD becomes a trivial field theory at the high energy limit will be a breakthrough.

This will bring a new direction of thinking for the unification of the mathematical model of strong and weak electricity.

These are valuable things.

......

With a long sigh of relief, Xu Chuan sorted out the papers on the table and sent a message to Zheng Hai, asking him to pick him up.

"I need to do some research these days, and if there's nothing important, don't bother me."

In front of the villa, as soon as Xu Chuan pushed the car door, he remembered something, stopped his movements and turned his head to Zheng Hai in front of him.

"Okay Professor, do you need me to prepare something for you?"

"No need, you have everything you need to prepare, and you can't get what you want to prepare."
