Into Unscientific

over a week ago.

When writing to Jia Xian, Lao Su once mentioned some situations to Xu Yun:

Jia Xian is old, and he usually studies some relatively profound arithmetic problems, and he is not moved by money.

If you want to convince him to come to Bianjing for help, you have to come up with enough weight to make the other party's heart beat.

Therefore, when choosing a letter to leave a message.

Xu Yun could only rack his brains to write down some knowledge that Jia Xian was most likely to be interested in.

For example, yin and yang are odd-even changes, a small number of binomial problems, and

In "Nine Chapters of Arithmetic", there are very famous cubic problems and so far there are not many solutions.

The result was unexpected.

Xu Yun's 'dosage' seems to be a bit large, and the other party is already on the way to crawl along the network cable.

Of course.

due to viewing angle limitations.

Xu Yun didn't know that he had a reader who was about to come to deliver blades in person, and this guy was still teaching a class leisurely.

On the second day after Wang Yue recovered from his illness, he met Xiao Li, who came to the door on time in the mansion again.

"Miss Li."

Xu Yun first greeted Xiao Li, whom he knew very well, then glanced behind her in surprise, and asked:

"Why don't you see His Highness King Jian today?"

in the past period of time.

Xiao Zhao and Xiao Li will come to the door almost every one or two days, and they will listen to Xu Yun teach the introductory knowledge of physics together with Lao Su.

Ten days have passed now.

Even Xiao Zhao and Xiao Li, who have no physical foundation, can already do basic force analysis.

According to the agreement when the hall was dismissed two days ago.

Xiao Li and Xiao Zhao should have arrived at the mansion at the same time today, even if Xiao Zhao couldn't come because of something, he should have sent someone to deliver a message in advance.

After all, people in ancient times still attached great importance to the concept of keeping promises.

Even if you are releasing pigeons, you have to abide by the etiquette, and even pay some gifts or something to express your apology.

Unlike some authors in later generations, they clearly murmured but did not express anything.

Hearing Xu Yun's inquiry, Xiao Li's face suddenly became solemn:

"Wang Lin, there are temporary changes in the palace today, and His Royal Highness Jian Wang may not be able to attend the class."

Xu Yun blinked and said in surprise:

"In the palace? Isn't His Highness King Jian no longer involved in palace affairs?"

mentioned earlier.

After Song Huizong ascended the throne.

In order not to arouse suspicion, or to save his life, Xiao Zhao's personality was 'forced' to undergo a huge change.

Not only hang around in restaurants and brothels, but also never go to the court meeting that should be attended, and hardly have any contact with the court.

Even because of this, Zongzheng Temple visited the book several times, but they were all suppressed by Song Huizong's "magnanimity".

In this background environment.

Xiao Zhao ran into the palace today, how could this not surprise anyone?

Seeing the surprise on Xu Yun's face, Xiao Li first glanced around.

After confirming that there is no one around, he lowered his voice and said:

"Last night at Yinshi, the Empress Dowager fell during the night, and the situation seems to be not good."

When Xu Yun heard this, his pupils shrank immediately.

To the Queen Mother.

This is a character who has little role in the history of China, but cannot be ignored.

It is said that she has no weight, because her past life has no waves:

She is the great-granddaughter of Prime Minister Xiang Minzhong and the queen of Song Shenzong Zhao Xu. In 1085, Song Zhezong succeeded to the throne and honored her as the empress dowager.

In the history of China, there are definitely not many women with similar experiences, but they are not too few.

From when Yingzheng proclaimed himself emperor in Qin Dynasty to the end of Puyi, there were more than 400 emperors in Chinese history, and it is conservatively estimated that there were still some empress dowagers in their early 300s.

Compared with empress dowagers like Cixi, the empress dowager Xiang really has nothing to shine.

As for not being ignored.

It was mentioned earlier when introducing classmate Xiao Zhao that she was the biggest contributor to Song Huizong's rise to power, and she could even be regarded as the only help.

From a qualitative point of view.

The queen mother's choice to know people unknown or to forcibly support Song Huizong in order to protect her status was a key turning point in the Northern Song Dynasty's sudden death.

Therefore, as a Song fan, Xu Yun also vaguely remembers the cause of death of the Queen Mother:

1101 AD.

Empress Dowager Xiang died suddenly on a certain day in the first lunar month due to a sudden stroke.

At the age of fifty-six or fifty-seven.

Before that, the history books recorded her as 'the body is fine'.

That is to say

According to the normal historical trajectory, it seems that the Queen Mother may probably

Have you never fallen before?

Think here.

Suspicion flashed across Xu Yun's eyes.

Because he thought again.

Old Su.

It is also developing according to the normal track. At this time, Lao Su should have set off from Bianjing and rushed back to his hometown Jingkou.

But in this case.

Because of Xu Yun's sudden appearance, Lao Su gave up the idea of ​​returning to Jingkou and stayed in Bianjing temporarily.

In addition, I rescued Wang Yue who was supposed to die. It can be said that from the perspective of the timeline, there has been a very serious discrepancy between the dungeon and the standard line of history.

More critically.

Xu Yun, or many experts in later generations have made guesses:

Lao Su will die of illness next year, most likely because he fell during the period, which led to a sudden depression of mental state.

So suppose—just suppose, what if Lao Su's fall happened on the way back to Jingkou?

So is it possible to derive another guess:

The fall to the queen mother should have happened to Lao Su?

It's like the butterfly effect that has been said countless times.

Xu Yun flapped his wings on Lao Su's mansion, and the Queen Mother Xiang in the palace was blown down?

Of course.

This is just Xu Yun's baseless guess, without any evidence to prove it.

After all, there is a full nine hundred years between this era and later generations, and no one can tell what the real historical details are.

Maybe in the real history, the queen mother fell like this, and everything was just a coincidence?

Then Xu Yun shook his head and pushed these thoughts to the back of his mind.

Turning around to Xiao Li, he said:

"The Queen Mother is ill, and as a junior, His Royal Highness Jian Wang, it is reasonable to go to visit her.

That being the case.

Miss Li, let's do our business first, the master is already waiting in the study. "

Xiao Li nodded when he heard the words, a glimmer of expectation flashed in his eyes.

Then Xu Yun led Xiao Li through several courtyard walls, and finally arrived outside Lao Su's study.

Or to be precise, it is Lao Su's academy:

As a great book collector that Emperor Shenzong of the Song Dynasty envied, there are tens of thousands of books in Su's house in Shiji, which can be called a vast ocean.

in normal history.

When Lao Su returned to Jingkou, he even directly contracted the convoys of three companies and dispatched dozens of carriages to transport his stored books back to Jingkou.

So in this mansion.

The place where Lao Su collected books was not a room, but a courtyard composed of three two-story attics.

When Xu Yun and Xu Yun arrived at this courtyard, Old Su was sitting on a stone table in the courtyard, looking at a microscope.

That's right.

microscope.

Of course.

This is a simple microscope provided by Xu Yun and crudely crafted by craftsmen, with a magnification of only more than 20 times.

After all, higher magnification precision lenses need to be prepared through calculations, such as the mirror grinder formula of 1/f=(n-1)(1/r1-1/r2) and so on.

At the same time, various indexes of glass products should also be considered.

Even if Xu Yun directly applied the formula, it would take at least half a month to complete it.

Not to mention that Xu Yun's plan is to let Lao Su and the others conduct the experiment by themselves, which will take even more time, at least a month or more.

But high-magnification precision is one thing, and low-power microscopy is another.

Just like Lao Su himself once created a five-times-level telescope.

In the Northern Song Dynasty, without professional formula derivation, you could grind out a set of low-power microscopes by hard grinding.

Although a microscope with a power of more than 20 times is not enough to observe the cell structure, it can barely be used as an entry-level device in the microscopic field.

At least satisfy Lao Su's curiosity or something.

After entering the courtyard, Xiao Li bowed to Old Su obediently:

"Morning, Uncle Su."

"Oh, Qingzhao is here."

Old Su moved his eyes away from the microscope, and first greeted Xiao Li.

Then he let out a sigh, and asked the same topic as Xu Yun:

"Huh? Why don't you see His Highness King Jian?"

Xiao Li and Xu Yun looked at each other, and Xiao Li repeated what he said earlier:

"Go back to Uncle Su, something happened in the palace today"

After Old Su listened quietly, a gleam of light flashed quietly in his eyes:

"What? The Queen Mother fell down?"

As a former prime minister, Lao Su was able to maintain a long-term neutrality between the old and new parties, and his political skills are actually quite high.

Now that he suddenly heard the news that the Queen Mother had fallen, almost immediately, many speculations flashed through his mind.

"If the Empress Dowager recuperates and delegates power, the pressure on King Jian will probably be even greater."

However, considering that Xiao Li can only get a rough idea of ​​the situation, it is obvious that there is no way to know the inside information, and naturally many judgments cannot be made accurately.

Therefore, after thinking about it, Lao Su decided to put the matter aside, and planned to inquire about it through his own channels later.

Then he pulled his thoughts back to reality, picked up a box from the table, and said to Xu Yun:

"Xiao Wang, there are cockroaches that were beaten to death in the box. According to your requirements, a glass sheet was pressed on it. You can see if it fits."

Xu Yun took the wooden box, gently removed the lid, and looked inside.

Only at this moment.

In the wooden box are several glass tablets of cockroaches, which have been sterilized with alcohol in advance, so they don't look particularly disgusting.

I don't know who made the tablet, but the air tightness and uniformity are very good.

Then Xu Yun took an empty glass slide and moved the microscope under the shade of a tree.

Adjust the stage to the lowest position again and start the operation.

I saw him put the slide into the gap at the back of the slide holder, and slowly push the slide forward with both hands.

At the same time, he said to Lao Su and the other two:

"Loose motion to place the slide and make sure it is facing the light aperture.

Then look at the eyepiece with the left eye, and turn the reflector with both hands like I did until the bright field of view is seen. "

Old Su looked at Xu Yun's posture of turning the reflector, and repeated it empty-handed.

Then nodded, indicating that he had remembered.

Xu Yun continued to operate while explaining:

"After the light is adjusted, start to slowly rotate the converter so that the low-magnification objective lens is aligned with the light hole."

"Then stare at the objective lens with both eyes, and rotate the coarse quasi-focus screw to slowly lower the lens barrel until the objective lens is close to the glass slide."

"Look at the eyepiece with the left eye, rotate the coarse focus helix, and slowly raise the lens barrel.

"Until the object image is seen, then fine-tune the object image through the fine-focus spiral to make the object image clear."

After finishing the last step, Xu Yun clasped his hands together and said:

"This is the focusing step of the microscope. After these steps are completed, the image can be observed."

Old Su nodded, and was about to ask some questions about the steps that he didn't remember clearly, but he heard Xiao Li on the side say:

"Wang Lin, can I try this microscope?"

Xu Yun was taken aback when he heard the words:

"Miss Li, have you memorized all these steps?"

Xiao Li tilted his head, and seemed to be a little confused:

"It's not that I have memorized it all, but I feel that I can recover it."

Xu Yun thought about it for a moment, then disrupted the order of the microscopes and gave way:

"Miss Li, come and try?"

Xiao Li didn't hesitate too much, and walked over generously, and picked up the slide somewhat jerky.

While talking to himself, he restored Xu Yun's operation:

"Slice first. Adjust the aperture and rotate the coarse focus spiral. Then the eyepiece.. Fine focus spiral. Finished!"

Xu Yun looked at this little bean sprout in surprise.

To know.

in the past few days.

In the small class consisting of Xiao Li, Xiao Zhao and Lao Su, everyone's learning progress is different.

Among them, the fastest is naturally Lao Su.

As a contemporary master with a certain amount of physics knowledge, Lao Su has already learned the concept of acceleration from his physics knowledge.

After class, Xu Yun would be asked to make up lessons for him, sometimes for several hours.

A few days ago, he took Xu Yun to the hill outside Bianjing City to do a Galileo iron ball experiment.

Among the remaining two, Xiao Zhao and Xiao Li, Xiao Li's progress was much slower than Xiao Zhao's.

In many cases, what Lao Su and Xiao Zhao can understand at once, Xiao Li has to think about it two or three times before he can understand it.

After all, this girl is a liberal arts student in the standard sense.

Interest is one thing, thinking and receptivity are another.

But what Xu Yun didn't expect was that.

Xiao Li, who is somewhat stuck in physics and mathematics, seems to have some talent in biology?

that's interesting

Of course.

Whether this little bean sprout can follow the path of biology in the future still needs further observation.

After all, at the end of the day, it's just a microscopic step-by-step reduction.

Then Lao Su also tried to get started, and after confirming that he had mastered the relevant steps, Xu Yun officially replaced the slices with cockroach specimens.

The observation effect of a microscope with more than 20 magnifications is actually similar to that of the macro cameras of later generations-if you are interested, you can search it on a certain treasure, and the camera with 15 or 20 magnifications is only a dozen yuan.

It is also good to buy it and attach it to the keychain, and occasionally look at the flowers and plants.

Although the cells cannot be seen at this magnification, some organs of the cockroach can be seen clearly under several times of magnification.

"I see."

Looking at the magnified hind legs of the cockroach, Old Su thought deeply:

"Cockroaches can stand on the wall because there are so many fine barbs on their feet.

The barb hooks onto the wall bump so it doesn't fall off the wall"

"Not only that."

Xu Yun on the side picked up a cockroach egg with homemade tweezers, and said to Old Su:

"I'm afraid you don't know that cockroaches only need to mate once in their lifetime to reproduce continuously.

At the same time, they carry a large number of pathogenic bacteria on them. Throughout the ages, countless plagues have been caused by cockroaches and wasting insects.

Therefore, if possible, cockroaches and wasting insects should be eradicated as much as possible. "

Old Su nodded slightly, remembering this matter in his heart.

Although he has retired from office, he will not stand idly by when it comes to the source of the plague.

After all, in the past dynasties, the number of civilians who died due to the plague is unknown.

In a sense.

The plague is consuming the fortune of the country and hollowing out the cornerstone of the country.

If the facts are as Xu Yun said, then

Cockroaches should be killed!

Then Lao Su glanced at Xiao Li who was at the side. At this time, the girl was observing an ant, and she seemed quite interested.

He couldn't help but reached out and touched the microscope, and said in admiration:

"Wei Wei Wei, Xiao Wang, this thing is really as mysterious and abnormal as you said.

The cockroach organs can be seen clearly with a 20-fold lens, so if you can magnify it 500 times, you may really be able to see the subtle things that are difficult to see with the naked eye."

Although in the past few days, Lao Su has gradually accepted many concepts proposed by Xu Yun.

But as a master of ancient science, he is still cautious about some concepts.

Such as microorganisms.

After all, this thing is different from the electrolytic cell of a generator. What Xu Yun always put forward is only a theory, and there is no empirical evidence.

It's one thing to accept it, quite another to fully believe it and even embrace it as the truth.

At least before actually seeing the microorganisms or bacteria, Lao Su would have some doubts more or less.

This is actually a very normal psychology, which belongs to human nature.

After all, in a sense.

These concepts proposed by Xu Yun are far more outrageous than brainwashing, basically the same as reshaping cognition

It can only be said that as Xu Yun shows more and more scientific tools, the possibility of this kind of possibility is also increasing, and it is infinitely close to the real hammer.

And just as Lao Su was talking with Xu Yun.

At the door of the study courtyard, the figure of Mr. Xie Guan suddenly appeared:

"master."

Seeing this, Old Su quickly brought his thoughts back to reality:

"Oh, the first year, what's the matter?"

Mr. Xie Guan hurried forward, handing over something similar to a greeting card.

Then he whispered a few words with Lao Su.

Old Su was overjoyed when he heard the words, and hurriedly said:

"Really? Hurry up, please!"

Mr. Xie Guan bowed to accept the order, while Mr. Su looked at Xu Yun:

"Xiao Wang, the person you were waiting for is here."

"Who am I waiting for?"

Xu Yun was taken aback for a moment, and then thought of something:

"Could it be Mr. Tongyu?"

The voice just fell.

Outside the academy.

Then came an old but carefree voice:

"Where is Wang Lin? Broken dog, don't update quickly!"
