Into Unscientific

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 strictly speaking, the quality of the glue does not depend entirely on the viscosity, and sometimes internal stress and the like must 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, took out another report and handed it to Xu Yun:

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

Xu Yun quickly took the report and read it.

in biology.

There are three main types of exocrine gland secretion:

local secretion.

Apocrine secretion.

and whole plasma secretion,

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

Dogs do not have sweat glands, so they can only stick out their tongues 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 in the skin of the whole body other than the soles of the feet, while the urinary glands of the small sweat glands are only distributed in the skin of the soles of the feet.

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

Some cats and dogs get skin bacterial infections that are essentially infections of the sweat glands.

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.

The axial swelling of native donkey hair was only 1% when the relative humidity was increased from 0 to 100%.

However, the ratio of Young's modulus to shear modulus decreased from 217:1 to 15:1.

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

That's right!

There is something between the donkey's hair, which firmly binds the axial swelling of the donkey's 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 about it for a while, theoretically it seemed

Is it possible?

after all

Matter and elements are not the same.

There are 118 elements that have been discovered so far, but the substances they combine may have countless situations.

Take the simplest example, coffee beans.

The taste of coffee beans roasted by the two methods of 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 some substances 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 substances containing nickel alone.

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

Naturally, this possibility also exists for native donkeys.

And don't forget.

The early gelatin, donkey-hide gelatin, came from donkeys:

Donkey-hide gelatin was used to paste the flute film long ago, it is thin and sticky, so——

Maybe what Qiu Sheng said really existed?

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

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

Donkey hair is also used in microbial batteries.

The hemostatic gelatin requires donkey sweat.

hiss.

Will there be other technologies in the future that will also be used by donkey brother?

Just as Xu Yun's thoughts spread.

In the donkey pen.

Brother donkey, who was resting after making love with donkey sister, suddenly got a shock, opened his eyes in horror, and looked around quickly under donkey sister's surprised eyes.

After a few seconds.

Donkey brother 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, and 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, for sure!

Lu Xun once said a famous saying:

The joys and sorrows of people and donkeys 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:

There is something wrong!

"Old Xu, I think so."

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

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

"Different from some other chemical or physical experiments, the abnormalities 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:

"Anyway, you don't need money, so 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 saying this.

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

Zhao Zhengguo:

".?"

ten minutes later.

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

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

"Academician Zhao, I'm sorry to keep you waiting for a long time. I don't know what you want to do with 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 earlier?"

Xu Yun nodded:

"of course I remember."

Students with good memory should remember.

After completing the copy of the Northern Song Dynasty, the reward Xu Yun received once included a formula.

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 copy.

Xu Yun once heard that the results of the experiment had already been obtained, but they were kept highly secret. At that time, even Xu Yun, the person who discovered the orbit, was told that the specific content could not be transmitted by phone or the Internet. Get in touch with him.

be honest.

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

It's just unexpected.

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

It's even so important that Zhao Zhengguo personally contacted him.

Who is Zhao Zhengguo?

This is a dignified member of the Huaxia Academy of Engineering. He used to be the leader of the Yanjing Spectrometer Calorimeter Group at 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, Zhao Zhengguo can be ranked among the top three.

An incident that would allow such a big boss to come here to notify him would definitely not be so 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.

Seeing this, Xu Yun didn't stop it, let alone saying "Qiu Sheng is not an outsider" - he and Qiu Sheng have been friends for two lifetimes, but Zhao Zhengguo didn't know it.

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

If Qiu Sheng is forced to stay, it will appear that his EQ is very low.

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 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 twenty centimeters above the table:

"Just this one condition?"

"Well, just this one."

When Xu Yun heard this, doubts arose in his heart, 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 so far."

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

"Is it possible that it is meson?"

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

"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 is an intrinsic degree of freedom of particles.

According to the Pauli exclusion principle.

If two identical fermions have exactly the same wave function, then their overlapping wave functions give a distribution probability density of 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 problem-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 know the difference between driving cars, high-speed rail or even green leather cars.

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

in the lab.

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 semi-odd, the observation level of the interaction phenomenon is 140Mev, 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 long time, but he couldn't see any sign of a joke.

After a few seconds.

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

"Academician Zhao, is what you said true?"

Zhao Zhengguo did not show the slightest 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 seen as a fat man.

Meson can be regarded as a thin man.

You let a thin person and a fat person run 100 meters together. 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"

"Jump?"
