Into Unscientific

Chapter 202: The Big One is Coming (7.4K)

As the current top1 in the field of quantum encryption in China.

Academician Pan's attainments in particles are also very high, after all, the two are similar in some respects.

In addition, he knew Xu Yun's ability and character quite well, and he knew that this student would not speak big words easily.

For example, he never pays back the updates he owes, never delays, etc.

So after receiving Xu Yun's report.

He immediately informed Zhao Zhengguo who was on campus at HKUST about the situation.

half an hour later.

Xu Yun came outside the National Synchrotron Radiation Laboratory of HKUST, and entered the base through the access control card.

From the outside, the Tongfu Laboratory of HKUST is actually very ordinary, a bit like a covered gymnasium—the kind with very old decoration.

The main entrance of the laboratory is a parking lot. There is a small fountain pool in the center of the parking lot. There are often riotous operations that do not spray water during the day and early morning.

But that's just the appearance.

The real core of the co-radiation laboratory is not on the ground, but underground.

The upper part is actually called the light source storage ring hall. In the center of the hall is a large device similar to a wellhead, which leads directly into the ground.

In the depths of the laboratory, there are circles of special coil equipment, and the price of one meter starts from 50,000 to 60,000 yuan.

At the same time, it is different from the first-generation light source used by the Yanjing Electron Positron Collider.

The same radiation uses the second-generation light source, and it is currently the only second-generation light source collision device in China.

In his previous life, when Xu Yun was studying, he was frightened by a senior, saying that a bag of instant noodles would be useless for two days.

It was only later that he realized that it was those old birds teasing the newcomers, and they liked to use this as a pretext to go along with the cute new instant noodles when they had nothing to do.

Although Xu Yun had been frightened for several days, he really didn't have any complaints about it.

At first, it was mainly a kind joke made by the seniors. In fact, they would often bring some delicious food over to share with everyone. In that environment, everyone was very close.

Second is

The ones that Xu Yun was sent away were old sauerkraut noodles. I don’t know how the senior feels now. Anyway, after the 315 party, Xu Yun directly chatted and reposted related videos.

The line of sight returns to reality.

The place agreed by Academician Pan and Xu Yun is next to the light source storage ring hall, in a meeting room dedicated to sub-high levels and above.

When Xu Yun arrived outside the meeting room.

The door of the meeting room is opening inwards, allowing one to see the situation inside.

At this time, Academician Pan sat on a chair opposite another man with a round face and a strong hairline, talking and laughing happily with his legs crossed.

Xu Yun leaned half of his body into the room, and knocked lightly on the door:

"teacher."

Academician Pan looked up at him and nodded:

"Oh, Xiao Xu is here, come in quickly, remember to close the door."

Xu Yun answered yes, closed the door after entering the house, and quickly walked in front of the two:

"Hello, Teacher, and Academician Zhao."

The academician Zhao that Xu Yun mentioned was naturally Zhao Zhengguo, one of the current academicians of the School of Physics of the University of Science and Technology of China.

He is sixty-six years old this year, a little older than Academician Pan, and an old man of HKUST.

Although Zhao Zhengguo's reputation at home and abroad is not as good as that of Academician Pan, he is also an extremely capable scientist.

He is an academician of the Chinese Academy of Sciences elected in 2013, one of the candidates of the Hundred Talents Program, and is currently the general director of the Particle Physics and Technology Research Center of HKUST.

At that time, he also served as the head of the University of Science and Technology of China, a member of the ATLAS international cooperation group of the LHC main detector. Today, the flying π meson beam that many students have a headache is observed by him.

After seeing Xu Yun.

Zhao Zhengguo pressed the cigarette butt into the ashtray, and opened his mouth with a very Chinese greeting:

"Xiao Xu, have you eaten yet?"

Xu Yun smiled at him:

"have eaten."

Zhao Zhengguo nodded and motioned Xu Yun to sit down.

Then he paused, and asked straight to the point:

"Xiao Xu, Xiao Pan came to me just now and said that you accidentally discovered a particle track?"

Xu Yun pondered for a moment when he heard the words, took out his notebook from his backpack, and logged into the Aurora system.

Then he pushed the notebook in front of Zhao Zhengguo and said:

"Academician Zhao, I've uploaded all the data to the Aurora system, um. It's been from this line of work."

Zhao Zhengguo took the notebook steadily and read it carefully.

After looking at it for a while, he raised his head in surprise:

"S wave separation 32.7? So light?"

well known.

The lower the S-wave separation, the longer the S-wave phase shift, that is, the lower the scattering amplitude.

What does this mean?

It's like bungee jumping.

Due to the conversion of gravitational potential energy into kinetic energy.

The vibration amplitude produced by a normal person and an ear root after falling is different, and the lighter the person, the smaller the vibration or amplitude will be.

The Λ hyperon is a kind of hyperon with the smallest mass, and the 4685Λ hyperon observed by Zhao Zhengguo and his colleagues is the lightest among all Λ hyperons.

That is, its S-wave separation is the smallest.

But even for the ultralepton such as the 4685Λ hyperon, its S-wave separation is still as high as 34.2.

But the particle deduced by Xu Yun right now, the S-wave separation formula is only 32.7.

In other words.

The new particle deduced by Xu Yun is lighter than the existing 4685!

that's interesting

Then Academician Zhao continued to read.

A few seconds later, his brows raised again.

in the microscopic realm.

The orbits of particles involve extremely deep angular momentum problems, so the orbits of each particle are generally far apart.

To use a realistic analogy, A and B are two magnets that can attract each other. If they want to slide on the ice, the distance between them must not be too close.

For example, every three and five meters will do.

But the particles deduced by Xu Yun right now are not.

The orbit of it and the 4685Λ hyperon is equivalent to only five or six centimeters in reality, but the two do not interfere with each other, which is a very, very rare situation.

Think here.

Zhao Zhengguo immediately sat up, took out a pen and a piece of paper from his body, and began to calculate seriously.

rustle——

The sound of the pen tip sliding was like a natural white noise in the quiet conference room, which made people feel inexplicably calm.

Xu Yun and Academician Pan just sat quietly, waiting for Zhao Zhengguo's calculation results.

As the saying goes.

There is a sequence of hearing, and there is a specialization in the art industry.

Zhao Zhengguo, as one of the leaders in the domestic particle field, has much higher attainments in related fields than Xu Yun and even Academician Pan.

Like a pulse.

Ordinary people may only feel the rattling vibration when feeling the pulse, but old Chinese medicine practitioners can use this to judge your physical condition, when to start a meal, and so on.

Twenty minutes later.

Zhao Zhengguo exhaled, slowly put down his pen, picked up the water glass and took a sip.

At this time Xu Yun noticed that his fingers seemed to be trembling slightly.

After a few seconds.

Zhao Zhengguo put down the water glass, turned to look at Academician Pan, and said with emotion:

"Xiao Pan, after Xiao Lu, you brought another good student."

Academician Pan glanced at Xu Yun and said knowingly:

"Academician Zhao, is Xiao Xu's deduction correct?"

"I'm afraid it's not as simple as being right."

Zhao Zhengguo took off his glasses, rubbed the bridge of his nose with his index finger and thumb, and then said:

"According to the results calculated by Xiao Xu, there is likely to be a special particle in that orbit, and the relationship with 4685 is likely to be consistent"

"Theory of Meson Exchange."

"Meson exchange theory?"

hear the word.

Academician Pan was taken aback for a moment, then his pupils shrank suddenly.

Meson Exchange Theory.

This is a theory that has been put forward for a long time, but the front-end research still has few results.

The interpretation of meson exchange theory is actually very simple:

The exchange of single π mesons produces long-range attraction between nucleons.

Double π meson exchange produces saturated mid-range attraction.

The exchange of ρ and ω mesons produces short-range repulsion.

Among them, the spin of π meson is zero.

called scalar mesons.

The spin of ρ and ω meson is 1.

called vector mesons.

Their rest mass is non-zero, which ensures the short-range nature of the nuclear force.

The non-scalar nature of the vector meson ensures the spin correlation of the nuclear force.

It involves relativistic single Bose exchange potential, non-covariant perturbation theory of nuclear force meson exchange, energy-independent N-N meson exchange potential and Paris potential, etc.

Simple right?

However, although the concept is well understood, it has not had any key results in practice.

At present, the best proof of the meson exchange theory is the kaon, plus a bottom quark D0 particle.

Meson is still like this.

Not to mention the hyperon, which is also a hadron.

What is the use of this theory?

The conceptual value is naturally the first to promote the study of nuclear force—the nuclear force here does not refer to nuclear power in the traditional sense, but refers to the force of atomic nuclei, which belongs to the type of strong interaction.

Students who are not mad at the physics teacher should remember it.

The four basic forces are gravity, electromagnetism, and strong and weak forces—the real interpretation of the latter two is the strong nuclear force and the weak nuclear force.

More critically.

All the forces that have been discovered so far are different forms of these four forces, without exception.

Therefore, the unification of the four is now one of the most important things in the physics world, and it belongs to the eighth unification in physics. (Play a small game, can someone write the first seven times in full, and if they can write it out, we will add another chapter this month)

If someone can unify gravity with the other three forces, his status will not be inferior to that of Einstein.

The meson/hyperon exchange theory involves the extension of strong and weak forces, and two or three steps behind it is the space-time model.

And gravity is the distortion of time and space, so this is a difficult but theoretically possible path on the road to unification.

So its theoretical value goes without saying.

As for the reality, there are two main points.

The first point is the theory of meson exchange. Or the study of Λ hyperons can assist us in the study of neutron stars.

When the spectral profile of the first black hole photo in human history was used, the hard drive for data collection used related technologies.

Other than that.

The Λ hyperon can also play an extremely important role in the optimization of the Milky Way model-this is a half-cold and half-hot knowledge, that is, we can observe many extragalactic galaxies at present, but the shape of the Milky Way is optimized through simulation.

Because we ourselves are in the Milky Way, we cannot observe the shape of the Milky Way from the outside.

It was not until 1918 that humans determined that the center of the Milky Way was in the direction of Sagittarius.

It was not until more than ten years ago that our solar system was located on the second cantilever of the Milky Way.

at the same time.

The related optimization of the Milky Way model is carried out every year. For example, we still don’t know how many black holes there are in the Milky Way. The number of star-level black holes in the Milky Way, which is derived from the initial mass function (IMF), is about 100 million, but There are only more than fifty known ones.

The Λ hyperon is a kind of particle that is extremely rich in neutron stars. If research results can be obtained on it, our understanding of the universe may be deeper.

Of course.

The real value closer to real ordinary people may be the second aspect - the optimization of electronic equipment.

The decay encryption of the Λ hyperon is also one of the current chip research directions, and its core lies in the maximum polarization.

Once the Λ superson can break through, mobile phones, supercomputing and even energy can get a substantial development.

As for the current research progress of the Λ hyperon?

Considering that some students have already failed the course and are about to cry, here is an explanation from someone who is not academically rigorous but actually has no difference:

The maximum degree of polarization can be regarded as the degree of exploration.

The 26% achieved by Zhao Zhengguo's team before means that the resolution of the Λ hyperon has reached a quarter.

This number is obviously insufficient in terms of research, just like if you play a quarter of a small movie, you may not even finish the foreplay.

But if a new particle that conforms to the exchange theory can be found, everything will be completely different.

Think here.

Academician Zhao couldn't sit still for a while. He looked at Xu Yun with an eager and sincere expression:

"Xiao Xu, can you authorize your data to our team for research?"

"You should know that our team can at least rank in the top three in the domestic super sub field, and there is no need to introduce it in terms of ability."

"If we can make a breakthrough in the Λ hyperon, then certain technological blockades will be a complete joke, this is not empty talk!"

"LHC's Run II discovered the God particle, but it implicated the electroweak unified field theory rather than the grand unified theory."

"If we can catch up with Europe and the United States in terms of hyperon theory, in this way, there is even a big chance to compete for the right to define the field!"

Having said this, the muscles on Zhao Zhengguo's face were trembling:

"That's the right to define"

"In this era, the right to define domains is domain hegemony! In a sense, it is"

"National luck!"

Looking at Zhao Zhengguo whose neck was flushed with excitement, Xu Yun suddenly felt a surge of emotion.

In today's Internet age.

Mention the word 'academician'.

Many people often think of words such as "parallel imports" and "benefit transfer".

be honest.

As the highest-level professional title in China, academician is destined to have nothing to do with politics and business.

Just like there must be a black character in a Hollywood movie, it is an unavoidable link.

But this does not mean that the title of academician is unworthy, and these cases should not be used as weapons to attack China's scientific research industry.

For example, the "Baijiu academician" criticized by many people.

In fact, she was only a co-opted person proposed by GZ Province, and she was not included in the final co-opted list.

There is also Yan Ning who has been mentioned by many people.

Her situation is more complicated. The main reason why she cannot be selected as an academician is that her teacher is someone Shi—this is a purely inner-circle problem. Didn’t the old cow overturn Hook’s desk back then?

There is also Cauchy, who directly killed Abel and Galois at an early age

This situation exists everywhere, some countries even more than domestic.

For example, Kolmogorov, Vladimir Arnold, and even Kenji Fukaya next door are also victims.

Another example is that many people like to talk about academician Li Ning's corruption, accusing so-and-so of falsifying papers and so on.

But the problem is that there are many overseas

For example, former Harvard Medical School professor and director of the Center for Regenerative Medicine, Piero Anvesa, had 31 papers retracted for academic fraud.

There are also brothers Michel and Andre Nussenzweig who were born in the famous family of immunology.

Their father's paper in 1980 laid the foundation for the scientific revolution in malaria molecular biology and vaccinology. Mother has published more than 230 scientific papers in her lifetime and won numerous awards internationally.

One of the two brothers is a professor of immunology at Rockefeller University, and a double academician of Eagle AAA and NAS.

The other is a cancer researcher at the Eagle National Institutes of Health, relying on the aura left by his parents to submit dozens of articles to the main journal of CNS.

The results of it?

These two brothers were later exposed to have falsified papers, and some of the results were simply posted by someone to post pictures, which is much more outrageous than domestic ones.

Another example is the Nobel Prize in 2018, which was even awarded to the two engineers who first discovered it, and a bunch of Princeton physicists were waiting for others to refuse it.

Those two engineers in the end didn't even go into academia, so what can you say.

Another example is that when it was rumored that 1,564 SCI papers were withdrawn worldwide, 536 domestic papers ranked first, and many people said, "Your country has serious fraud."

But what is the truth?

The fact is that among the 536 articles, 174 were withdrawn because the translation did not match the pictures, and many of them were republished after proofreading.

In addition, there are 41 papers by the Seven Men of National Defense—for details, you can search for the sanction of Harbin Institute of Technology across the sea, so I won’t go into details this time. In short, it has nothing to do with fraud.

After deducting these, the number of withdrawn journals in China is just over 300.

The number of journals withdrawn by Eagle is 255, and the number of journals published in China is 3.4 times that of Eagle. It is self-evident where the real hardest hit areas are.

It's a pity that due to the weak public opinion, few people know the truth, or no one really wants to know how many bowls of noodles you ate.

undeniable.

At present, there are indeed many problems with the domestic scientific research evaluation system. Many academicians are not all high-spirited academics. For example, Xu Yun himself knows some people who are corrupt or even engage in pornographic transactions.

However, it is completely unreasonable to criticize the scientific research evaluation system with an example.

This approach is also unfair to many academicians who devote themselves to scientific research.

Actually.

After Xie Jianping, an academician of Tobacco, became an academician, within a week, hundreds of academicians jointly requested to re-examine his qualifications.

It's a pity that there were too many involved in that matter, and some forces intervened in the end but failed.

Today, there are more than 800 academicians of the Chinese Academy of Sciences, and nearly 900 academicians of the Chinese Academy of Engineering, adding up to 1,700.

There may be only fifty or sixty "false academicians" rumored on the Internet without any evidence.

Many of them were anonymously splashed with sewage, but even if they were all problematic, what proportion of these people accounted for the whole?

The remaining 1,600 academicians like Zhao Zhengguo, many of whom can't even pronounce their names, but actually made a lot of contributions, were all aoe'd together like this?

How lamentable.

Think here.

Xu Yun couldn't help but took a deep breath and forced himself to calm down.

Then he glanced at Academician Pan, who nodded knowingly.

After getting his teacher's permission, he immediately said to Zhao Zhengguo:

"Professor Zhao, you can just copy the data over there. We are all from the University of Science and Technology. If we don't support you, who else should I support?"

Zhao Zhengguo was taken aback for a moment, and then he patted Xu Yun on the shoulder heavily:

"Good boy, you are indeed Xiao Pan's student, so I won't be polite!"

Xu Yun gritted his teeth and rubbed his arms. Academician Zhao's strength is really worthy of his hairstyle.

Since the project of particle collision needs to be approved by the superior department, many links are involved.

Therefore, the experiment must not start immediately.

For example, the collision level of the University of Science and Technology ranks third in China. Although the energy level of the second-generation light source is lower, the cost of scientific research is still high.

Such a collision of Λ hyperons usually requires more than a month of preparation, and the related funds are about 5 million Huaxia coins, which can be collided about three times.

Don't be too expensive, this is because the binding energy of the Λ superson is not high.

Like the LHC in Europe, which cost 8 billion U.S. dollars, it costs more than 2 million U.S. dollars to start up.

It is the beginning of December now, and if everything goes well, the project will probably start in mid-January next year.

half an hour later.

The data transfer between the two parties is completed.

Seeing that Zhao Zhengguo was going to report on the project, and Pan Shuai seemed to have a task to do, Xu Yun got up tactfully and bid farewell.

As a result, as soon as he left the Tongfu laboratory, the mobile phone in his pocket rang.

"If there is time before dark, I will goug your eyes~"

Xu Yun took out his phone and looked at it.

The person who came was Gu Qunqing.

He quickly walked to a shaded place and answered the phone:

"Hello, Aaron?"

After a while.

Gu Qunqing's hasty voice came from the other end of the phone:

"Dr. Xu, something happened!"
