MTL - Into Unscientific-Chapter 355 Zhao Zhengguo's Purpose of Coming (Part 1)

  Chapter 355 Zhao Zhengguo's Intention (Part 1)

  Inside the laboratory.

   Hearing Qiu Sheng's words.

  Xu Yun's pupils shrank suddenly.

  The rheometer mentioned by Qiu Sheng belongs to the detection method of oscillatory rheology, which can be used to detect the viscosity of most adhesives.

  Although in a strict sense, the quality of the adhesive does not depend entirely on the viscosity, and sometimes internal stress and the like must also be considered.

   But the viscosity of the donkey hair compound was just measured by Qiu Sheng, which can explain many problems.

   Then he glanced at Qiu Sheng and asked seriously:

   "Old Qiu, the slime you're talking about is the sweat of a local donkey?"

  Qiu Sheng nodded heavily, pulled out another report, and handed it to Xu Yun:

   "That's right, to be precise, it should be the apocrine secretion of a local donkey."

  Xu Yun quickly took the report and read it.

   In biology.

  Exocrine glands secrete mainly in the following three ways:

  Secret locally.

  Apocrine secretion.

   and whole plasma secretion,

  On the Internet in 2022, you can often see such a saying:

  A dog has no sweat glands, so it can only stick out its tongue to dissipate heat—the dog here does not refer to the dog author, but a real dog.

   But actually.

  This statement is not correct.

  In fact, the dog's apocrine glands are distributed on the skin of the whole body except the soles of the feet, while the urinary glands of the small sweat glands are only distributed on the skin of the soles of the feet.

   It's just that dogs, animals like this, can't regulate their body temperature by sweating.

  Some cats and dogs get skin bacterial infections that are essentially sweat gland infections.

   By the way.

  If you have a dog at home, you can try to smell the dog's feet, it is the smell of dog sweat, like stinky tofu.

   In addition to dogs, donkeys naturally also have sweat glands.

  The sweat glands of donkeys belong to the apocrine glands. During the secretion process of gland cells, the apical membrane of the cells is damaged, and a part of the cytoplasm at the top of the cells is discharged together with the secretions.

   And mentioned before.

   During the research process of Academician Yang.

  In the case of increasing relative humidity from 0 to 100%, the axial swelling of native donkey hair is only 1%.

  The ratio of Young's modulus to shear modulus is reduced from 217:1 to 15:1.

  It can be concluded from the fact that the content of this section at that time was not mentioned in this chapter. Students must have understood the meaning of the research results.

   That's right!

  There is something between the hair of the donkey, which firmly binds the axial swelling of the donkey hair.

  Now want to come

   Could it be that the substance causing this phenomenon is the kind of mucus that Qiu Sheng discovered?

  Xu Yun thought carefully for a while, theoretically it seems

  Is it really possible?

after all

   Substances and elements are not the same.

   There are 118 elements that have been discovered so far, but there may be countless kinds of substances that they combine.

   Take the simplest example, coffee beans.

  The taste of coffee beans roasted by dark roasting and light roasting is different, and the essence of this situation is that different substances are generated inside.

  Some substances are currently known, while others are temporarily unknown—the unknown here is not that it cannot be detected, but that it has no meaning of detection.

  In a normal cup of coffee, there are no less than a dozen or more nickel-containing substances.

  So you can often see XX sugars, XX acids, and XX-based compounds on the substance list, but you can’t see the specific names. This is the reason.

   coffee so

  Native donkeys naturally have this possibility.

   And don't forget.

  Ejiao, an early gelatin, came from donkeys:

   Ejiao was used to paste Dimo ​​a long time ago, it is thin and sticky, so—

   Maybe what Qiu Sheng said really exists?

  Thinking about it, Xu Yun's expression was slightly subtle.

  The anti-bad breath toothpaste that has not yet been interviewed needs donkey hair.

  Microbial batteries also use donkey hair.

  Hemostatic gelatin needs donkey sweat.

   Hiss.

   Will there be other technologies in the future that will also use Brother Lv?

   Just as Xu Yun's thinking spread.

  In the donkey pen.

   After loving the donkey sister, the donkey brother who was resting suddenly got a shock, opened his eyes in horror, and looked around quickly under the surprised eyes of the donkey girl.

   After a few seconds.

  Brother Donkey breathed a sigh of relief.

so far so good.

   It turned out to be a nightmare, it scared the donkey to death.

  Just now it dreamed in a dream that it had returned to the Song Dynasty and was made into donkey meat and burned. A group of people gathered around a big pot, chatting, laughing, drinking and sharing food.

   Burning donkey meat is the most terrifying torture in the world, nothing can surpass it!

  Well, definitely!

  Lu Xun once said a famous saying:

  The joys and sorrows of a man and a donkey are different.

   Therefore, Xu Yun and Qiu Sheng were not aware of the telepathy that Brother Lv had at this time. After reading the experiment report, they reached a consensus in a very short period of time:

   Got a head!

   "Old Xu, I think so."

  The two guys put their heads together, and Qiu Sheng held his fingers and said:

   "Look, although the microbial battery has only just been approved, and the coagulation gelatin is only in the conceptual stage, our current situation is a bit special."

   "Unlike some other chemical or physical experiments, the anomalies we found are all related to the derivatives of donkey brother, and the cost can be almost zero."

"so."

   "Can we take a step forward, approve a few thousand dollars to prepare some equipment, and then try to start research?"

   "I estimate that even if it fails, the final loss will only be two to three thousand yuan and dozens of catties of donkey hair."

  Xu Yun nodded in agreement and concluded:

   "It doesn't cost money anyway, just try a little bit."

   "Brother donkey now has a sister donkey, just like it doesn't matter if an old man loses his head after marriage, brother donkey's hair doesn't need to be kept particularly neat."

Do not know why.

  When I said this.

  Xu Yun subconsciously rolled his eyes aside Zhao Zhengguo's sparse head.

  Zhao Zhengguo:

  “.?”

ten minutes later.

  The prototypes of the two projects were established, and the bulk of the initial experimental cost was mainly the forage for feeding the donkey brother.

  After handling Qiu Sheng's affairs, Xu Yun turned to look at Zhao Zhengguo:

   "Academician Zhao, I'm sorry to keep you waiting, I don't know what you want from me today?"

  “.”

  Zhao Zhengguo’s facial muscles twitched twice, took a deep breath, and forced himself to calm down:

   "Xiao Xu, do you still remember the particle orbit you calculated before?"

  Xu Yun nodded:

"of course I remember."

  Students with good memory should remember.

  After completing the copy of the Northern Song Dynasty, Xu Yun received a formula once among the rewards he received.

  The formula can be divided into three sub-terms. Later, Xu Yun calculated and deciphered the first part, and found that it was an equation suspected of particle orbits.

  So he handed over the orbital data to Pan Shuai and Zhao Zhengguo for their research.

   Before entering the wheat instance.

Xu Yun once heard that the results of the experiment had been obtained, but they were kept in a high degree of secrecy—even Xu Yun, the person who discovered the orbit, was told that the specific content could not be transmitted by phone or the Internet. He makes contact.

be honest.

  Before today, Xu Yun already had some guesses about the unknown particle.

   Just didn't expect it to be.

  According to the analysis of the situation at this time, the importance of that particle far exceeded my expectation.

   It is even so important. Zhao Zhengguo personally contacted him.

   Who is Zhao Zhengguo?

   This is a dignified academician of the Huaxia Academy of Engineering. He used to be the leader of the Yanjing Spectrometer Calorimeter Group of the Institute of High Energy Physics of the Chinese Academy of Sciences, the director of the First Physics Office of the Chinese Academy of Sciences, and the director of the Experimental Physics Center. He is currently the leader of the Physics Particle Research Center of the University of Science and Technology of China!

  In the field of particle physics in China at present, Zhao Zhengguo can rank among the top three.

  An event that allows such a big boss to come here to notify him must not be too small.

   Then Zhao Zhengguo glanced at Qiu Sheng who was at the side, smiled and said to him:

   "Xiaoqiu, can I trouble you to go down and buy a package of Yellow Crane Tower for me? I will transfer the money to you on WeChat later."

  Qiu Sheng was taken aback for a moment, and immediately realized:

"no problem."

   After speaking, he patted Xu Yun's shoulder meaningfully, turned his head and left the laboratory.

  Xu Yun didn't stop him when he saw this, and he didn't say something like 'Qiu Sheng is not an outsider'—he and Qiu Sheng had been friends for two lifetimes, but Zhao Zhengguo didn't know it.

   Not to mention that Qiu Sheng himself obviously had this awareness.

  If you force Qiu Sheng to stay, it will appear that you have a low EQ.

   After Qiu Sheng left.

  Zhao Zhengguo straightened his face and said to Xu Yun:

   "Xiao Xu, before I tell you the results of the experiment, I want to ask you a question about particles."

  Xu Yun put two plastic cups in front of Zhao Zhengguo and himself, and poured a glass of water for Zhao Zhengguo first:

"You say."

   "Assuming that the spin of a certain particle is semi-odd, what kind of particle do you think it might be?"

   "Spin is half-odd?"

  Xu Yun stopped pouring water for himself, and the broken spout hovered 20 centimeters above the table:

   "Just this one condition?"

   "Well, just this one."

  Xu Yun was puzzled when he heard the words, but he still answered obediently:

   "Particles with semi-odd spins can only be fermions, and electrons, protons, neutrons, and baryons are all possible—this condition can only be analyzed here."

  Zhao Zhengguo looked at him with a smile, and asked again:

   "Then is it possible that it is a meson?"

  Xu Yun was stunned for a few seconds, then quickly shook his head:

   "It is absolutely impossible. Mesons are bosons, and the spin of bosons is an integer. This is an axiom. It can even be said to be a quasi-axiom."

   Well known.

  Spin belongs to the intrinsic degree of freedom of particles.

  According to the Pauli Exclusion Principle.

  If two identical fermions have exactly the same wave function, then the distribution probability density given by their overlapping wave function is 0.

  So fermions can only have half-odd spins, that is, 1/2, 3/2, 5/2, 7/2, etc.—sometimes also called half integers, and you can understand it by multiplying by 2.

   Electrons, protons, neutrons, and baryons are all fermions.

  Mesons, photons, weak gluons, and Higgs particles all belong to bosons, and their spins are integers.

  This is an uncontroversial public opinion in the microscopic field, and even Minke will not question this kind of question—because the conclusion of the collider is there.

  Bosons are an important medium for the transmission and interaction between fermions, such as trains and tracks.

in life.

  Some people may not use a car, a high-speed rail or even a green car.

   But in any case it is impossible to say that the track is a high-speed rail.

  In the laboratory.

  Looking at the swearing Xu Yun, Zhao Zhengguo sighed with emotion:

   "But Xiao Xu, do you know that the particles we calculated based on your orbit.

  “Although its spin is a semi-odd number, the observation level of the interaction phenomenon is 140 Mev, which belongs to the standard

   "The category of electrically neutral mesons."

  Hearing Zhao Zhengguo's words, Xu Yun's breath suddenly became stagnant.

  After recovering, his first reaction was

  Zhao Zhengguo was joking just like Commander Xue who had chicken soup.

   But he observed Zhao Zhengguo for a while, but he couldn't see any sign of a joke.

   After a few seconds.

  He finally couldn't bear it anymore, and asked tentatively:

   "Academician Zhao, is what you said true?"

   Zhao Zhengguo did not show any dissatisfaction at being questioned. After all, when he saw the result, he also had the same expression:

"real."

  Xu Yun was silent.

  The particles he calculated at the beginning theoretically belong to the category of hyperons, which are singular particles composed of three quarks whose mass exceeds that of protons.

   Metaphorically speaking

  Chaozi can be regarded as a fat man.

  Meson can be regarded as a thin man.

  You let a thin person and a fat person run together for 100 meters. Under the same distance, the energy consumed by the fat person—that is, the observation level of the interaction phenomenon must be more.

   That is, the half-odd spin (fat person) and the observed level of 140 Mev (belonging to the energy consumed by the thin person), the two cannot coexist at the same time.

unless

  Think here.

  Xu Yun's pupils shrank again, and he suddenly looked at Zhao Zhengguo:

   "Could it be that the movement of that particle is not 'running' but"

   "Jap?"
