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 aspects.

  In addition, he is quite familiar with Xu Yun's ability and character, and knows that this student will not speak big words easily.

  For example, he never pays back the updates he owes, doesn’t procrastinate, etc.

  So after receiving Xu Yun's report.

  He immediately informed Zhao Zhengguo who was on the campus of 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.

  The Tongfu Laboratory of HKUST is actually very ordinary in appearance, somewhat 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 riots in the daytime without spraying water in the early morning.

   But this is just the appearance.

  The real core of the co-spoke 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 Yanjing Positron Collider.

  The second-generation light source is used for the same radiation, and it is also the only second-generation light source collision device in China.

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

   Later he realized that it was those old birds teasing the newcomers, and he liked to use this as a name to go along with the cute new instant noodles

   Although Xu Yun has been frightened for several days, he really has no complaints about it.

  When I first came, 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.

  Secondly, it is

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

  The line of sight returns to reality.

  Academician Pan and Xu Yun agreed on a meeting room next to the light source storage ring hall, in a special meeting room above the sub-high level.

  When Xu Yun arrived outside the meeting room.

  The door of the meeting room is opening inwards, so you can see the situation inside.

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

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

"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 walked quickly in front of the two:

   "Hello, teacher, and academician Zhao."

  The academician Zhao that Xu Yun mentioned is 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 he is also an old man of HKUST.

   Although Zhao Zhengguo's reputation at home and abroad is not as high 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. Now many students have a headache flying π meson beams were observed by him.

   After seeing Xu Yun.

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

   "Xiao Xu, have you eaten yet?"

  Xu Yun smiled at him:

"Ate."

  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 after hearing 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 have transferred all the data to the Aurora system, um. It has been from this line of work."

  Zhao Zhengguo took the notebook steadily and read it carefully.

  After watching 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.

  A normal person and an ear base produce different amplitudes after falling, and the lighter the person, the smaller the fluctuation or amplitude will be.

  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 type is the smallest.

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

  But the particle deduced by Xu Yun 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!

   This is very interesting

   Then Academician Zhao continued to read.

   A few seconds later, his brows raised again.

  In the microscopic field.

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

  Using 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 are not the same.

  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.

  Shushasha—

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

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

   As the saying goes.

  There is a priority in hearing, and there is a specialization in art.

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

   is like a pulse.

  Ordinary people may only feel a rattling vibration when feeling their 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.

  Master 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 correct."

  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"

   "Meson Exchange Theory."

   "Meson exchange theory?"

   Hear the word.

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

  Meson exchange theory.

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

  The interpretation of meson exchange theory is actually very simple:

  Single π meson exchange 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.

   are called scalar mesons.

  ρ, ω mesons have a spin of 1.

   is called a vector meson.

   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.

   Pretty simple, right?

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

  Currently 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 hadron.

  As for 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 were not **** off by the physics teacher should remember it.

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

   More critically.

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

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

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

   So its theoretical value needless to say.

   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 obtained, the hard drive for data collection used related technologies.

   Other than that.

  Λ hyperons can also play an extremely important role in the optimization of the Milky Way model—this is 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 are inside 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 is 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 relevant 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 derived from the initial mass function (IMF) is about 100 million, but the real Only about fifty are known.

  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 actual value that is closer to the real ordinary people may be the second aspect—the optimization of electronic equipment.

  Λ hyperon decay encryption is also one of the research directions of the current chip, 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 subject 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 downloaded a quarter of your small movie, the foreplay may not be finished yet.

  But if a new particle that conforms to the exchange theory can be found, then 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 RunII 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, then there is even a big chance to compete for the right to define the field!"

   Speaking of this, the muscles on Zhao Zhengguo's face were trembling:

   "That's the right to define"

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

   "National Fortune!"

  Looking at Zhao Zhengguo, whose neck was flushed with excitement, Xu Yun suddenly felt emotional.

  In today's Internet age.

   Mention the word 'academician'.

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

be honest.

  Academician, as the highest professional title in China, 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 Guizhou 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 Lao Niu overturn Hook’s desk back then?

  Similar to Cauchy, he directly killed Abel and Galois who died young

   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 Regenerative Medicine Research Center Piero Anvesa, he had 31 papers retracted for academic fraud.

   There are also brothers Michel and AndreNussenzweig 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. In her lifetime, her mother published more than 230 scientific papers and won numerous international awards.

  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?

  The two brothers were later exposed to have falsified their papers, and some of their results were simply posted by someone else, 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.

  The last two engineers didn’t even go into academia, what can you say.

   Again, for example, 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.

  There are also 41 papers by the Seven Sons of National Defense—for details, you can search for the sanctions against Harbin Institute of Technology. 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.

  Unfortunately, due to the lack of public opinion, few people know the truth, or no one really wants to know how many bowls of noodles you ate.

   Undeniable.

  The current domestic scientific research evaluation system does have many problems, and many academicians are not all high-spirited and academically qualified. For example, Xu Yun himself knows some people who are corrupt or even engage in pornographic transactions.

  But it is completely unreasonable to attack the scientific research evaluation system with a single example.

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

   Actually.

  When Tobacco Academician Xie Jianping became an academician, within a week, hundreds of academicians jointly requested to review his qualifications.

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

  Now 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 "fake academicians" rumored on the Internet today without any evidence.

  Many of them were anonymously splashed with sewage, but even if they were all problematic, what percentage 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 permission from his teacher, 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 slapped 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.

  Because the particle collision project needs to be approved by the superior department, it involves many links.

   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.

   It usually takes more than a month to prepare for the collision of this kind of Λ hyperon, and the related funds are about 5 million Huaxia coins, which can be collided about three times.

  Don’t think it’s too expensive, it’s because the binding energy of Λ hyperons 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. 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 tactfully got up and bid farewell.

  As a result, just as he left the co-spoke laboratory, the cell phone in his pocket rang.

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

  Xu Yun took out his mobile phone and took a look.

  The person who came was Gu Qunqing.

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

   "Hello, Aaron?"

   After a while.

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

   "Dr. Xu, something happened!"

   Recently, I have to accompany my grandma. I didn’t wake up until 10 o’clock last night. It’s been all night until now, so sometimes the update may not be on time.

   Pushing a book, very interesting Hokage Stream, and it’s a work by a girl author~

   The title of the book is "My Ninja Cat Thinks I'm Weak and Steals the Fruit of Thunder"
