Into Unscientific

Eighteen days later.

A quiet summer night.

There are no dark clouds in the sky, and the sky is full of stars doing their best to blend the bits and pieces of light together.

Although not as brilliant as the sun, nor as clear as the moon, they still sprinkle starlight into the world like a dream.

A little bit of starlight shines together, turning the earth into a strange world, arousing people's desire to explore.

Compared with the vast starry sky in front of us, human beings are pitifully small, like dust.

Under the universe, human beings are as insignificant as ants on the ground.

But even ants are different from each other.

For example right now.

The night has come.

The 'ants' in Bianjing are either asleep, preparing for tomorrow's expenses, or going to the night market in twos and threes.

There are also some who lie on their sides on the knee pillows of the singers on the boat, enjoying some special fun.

And outside Bianjing city.

On a short but relatively empty hill, there is another group of 'ants' busy.

Dozens of servants were seen holding torches, surrounding an open space, providing light sources while guarding.

There were also twenty or thirty people standing in the open space, assembling and debugging in an orderly manner, and it looked lively.

"Be careful, be careful, three, two, one, together!"

"Left left, right right, right here, right here"

"Come on, let it go, let it go, let it go!"

"Where's the axle? Where's the axle?"

"Yongzhu, take the donkey away first, and you have to rely on it to pull goods when you go down the mountain!"

In this din.

Xu Yun stood beside a huge iron cylinder, doing the final adjustment seriously.

"Master Chen, align the polar axis with the North Celestial Pole! That's right, that's good!"

"Master Guo, check to see if the four hairsprings of the mainspring are wedged into the mouth of the sky."

"Lieutenant Wang, fix the right side a little more firmly."

About ten days ago.

Siegfried officially ground the lens and handed it to Xu Yun.

Then Xu Yun spent another day for fine grinding, and finally processed the NA value of the lens to between 1.18-1.20, and passed the final verification test.

However, even though everything was gathered together, he was not in a hurry to start astronomical observations.

First, astronomical observation has certain requirements on the environment, and the visibility must be high.

After all, if the sky is full of dark clouds, you can't observe it, can you?

Second is

Xu Yun has to wait for a special day.

Therefore, this class is a full ten days.

Of course.

It's not like Xu Yun didn't do nothing in the past ten days.

As always, I went to class not to mention, but also sat in a donkey cart many times and went out to inspect suitable observation points.

After some observation, I finally chose this small hillside.

The height of this hill is only about 100 meters, and it looks a bit low.

But in fact.

The interior of the hill is half-empty, and there is an extremely wide platform on the mountainside, which can accommodate hundreds of people.

According to what Mr. Xie learned about the situation.

This hillside was originally a clay kiln, but it was sealed up and abandoned because the original owner was involved in a corruption case, and the shipping platform on the hillside was preserved.

Now that several years have passed, Xu Yun has picked up a loophole.

After about a quarter of an hour or so.

Zieg quickly walked up to him and said respectfully:

"Prince Wang, all links have been adjusted."

Xu Yun bowed his hands to thank him, took off the water bag at his waist and handed it to him:

"Master Lao Qi is here, drink some water."

Then he walked to the right side of the barrel, put on gut gloves, and placed the finderscope lens into the side wing barrel.

mentioned earlier.

The telescope designed by Xu Yun has a diameter of one meter, a length of nearly ten meters, and a weight of five tons.

Therefore, if you want to fix the cylinder body while maintaining the steerability, you must use the method of tilting towards the sky and applying external fixing equipment for installation.

As for how it was pulled up the mountain?

In short, donkey brother contributed a lot.

It's only five tons, not heavy.

Actually.

A similar device appeared in the 19th century, in 1865.

At that time, the John Bull Royal Society invested heavily to build a large iron telescope weighing 8.9 tons for observation, and it still exists in the Oxford Museum.

Although the precision of the telescope designed by the Royal Society was not the highest at the time, its significance was extraordinary:

This is the first officially organized starry sky observation in human history.

This also represents a certain attitude of the British government towards science-although the fate of industry is full of blood and tears, at least in terms of scientific research attitude, the British royal family is still doing the right thing.

It's a coincidence.

At the same point in time, the local Emperor Tongzhi was also looking up at the sky.

However, he was not looking at the telescope, but only praying to ghosts and gods—that year when cholera broke out in the country, the people were naturally panic-stricken, so they could only turn to gods and Buddhas for help, intending to use astrology to determine national policy.

By the way.

Also this year, Nokia was just established

The line of sight returns to reality.

After everything is debugged.

Xu Yun walked to Lao Su's side and glanced at the surrounding people.

Everyone present today is except for Lao Su.

The two brothers Wang Ting, Xiao Zhao, Lao Jia and other six mathematicians, Siegfried, Xie Laoduguan, and Xiao Li's father and daughter all came - after all, Lao Li was a little worried about going out late at night.

in addition.

There are also several special characters present at the scene:

The one on the far left is a civil servant in his seventies, an official from the eighth grade who came from the Editing Academy.

The so-called editorial institute refers to the book editing institution affiliated to the Song Dynasty History Museum.

It is in charge of compiling and compiling national history, meetings, records, calendars, etc. It is not considered a department in power, but its nature is very special.

What Lao Su is going to do today is the first telescopic observation in the human history of this time and space, and such a pusher must be present.

But compared to this person's identity, his name may be a little louder:

His name is Zhang Huaimin.

That's right.

It was Zhang Huaimin.

He was demoted to Huangzhou four years later than Su Shi, but he had to return to his post earlier, and he returned to Bianjing in July last year.

The Tutor of the Editorial Institute was his last known position, and his birth and death have been unknown since then.

Standing beside Zhang Huaimin were two men in Tsing Yi.

One of them was about forty years old, his facial features were as sharp as knives, sharp eyes, tall and tall, and he looked like a hero.

The other is a burly old man with thick white beard and hair. His imposing manner is relatively restrained, but a scar on the left side of his face adds a bit of viciousness to him.

Judging from their standing posture and expressions, both of them are likely to be from the military, and their ranks are not low.

In fact it is.

The old man among them was Wang Hou mentioned earlier.

few days ago.

Thanks to the efforts of the two brothers Wang Ting and the attraction of alcohol and distilled wine, Xu Yun finally connected with this military boss and invited him to the scene through Lao Su's famous post.

As for the other middle-aged man.

It was Zhang Shuye.

It is also the prototype of Lin Chong in "Water Margin", one of the few conscientious officials in the late Northern Song Dynasty. Historically, he suppressed the Song Jiang Uprising.

But unfortunately.

According to the normal historical trajectory, Zhang Shuye's fate is similar to Wang Teng's, and it is also quite tragic.

In the year of Jingkang, Zhang Shuye also served as the governor of the South Daodu. The Jin soldiers approached Bianjing, and the royal family was in crisis.

After learning of the news, Zhang Shuye brought 30,000 people to serve the king with blood, which was the only large-scale establishment supporting Bianjing during the Jingkang Incident.

After Jin Bing further besieged Kyoto, Zhang Shuye fought against Jin Bing for four consecutive days, but in the end he was still powerless.

Later Song Qinzong drove out of the city to go to Jinying to surrender. Zhang Shuye knocked on his horse and remonstrated, and was escorted by Jin soldiers to go to the northern Jin Kingdom.

The second day after crossing the boundary river.

Zhang Shuye looked up to the sky and wept bitterly, hanged himself and died at the age of sixty-three.

Today's Zhang Shuye is the magistrate of Haizhou, and he just returned to Bianjing to report on his work a few days ago.

And because his grandfather Zhang Qi and Lao Su's father Su Shen were old friends, he came to the mansion to pay a visit, but was abducted by Xu Yun to the mountain.

After coming to Lao Su's side, Xu Yun cupped his hands towards him and said:

"Master, the telescope has been adjusted, and we can start observing the starry sky."

When Old Su heard this, his pupils shrank slightly, and even his body began to tremble faintly.

Do not know why.

This eighty-year-old man, who had looked up at the starry sky countless times, felt a rare sense of uneasiness in his heart.

To know.

Even when he was waiting for the list next to the old man with spicy soup, he had never been so excited before.

But after all, he was a prime minister, so there was a gap in his chest.

I saw less than half a minute.

Old Su took a deep breath and forced himself to regain his composure.

Afterwards, he refused the support of Old Du Guan Xie, straightened his sleeves, and walked slowly to the side of the telescope by himself.

He first looked up at the starry sky, remained silent for a moment, pointed at the crescent moon in the starry sky, and said to Xu Yun expectantly:

"Xiao Wang, can I show the old man the moon first?"

Xu Yun bowed his hands solemnly and nodded:

"no problem."

After speaking, he walked to the operating table, adjusted the star-seeking optical axis of the main mirror, and locked it to the area where the moon was.

The base of this telescope can be rotated by a dial, with the help of rollers and tung oil, it is still very easy to push.

The mercury paraboloid is guaranteed to rotate through another system, and the two will not interfere.

Then Xu Yun turned the three screws on the finderscope to adjust the image that was in the center of the main mirror just now to the center of the crosshairs of the finderscope as much as possible.

This step may seem simple, but it actually requires a lot of patience.

The cross must be aligned, and the three screws must be pushed against the lens barrel, even if it is a little bit off.

At the beginning, a fisherman who did not want to be named made a mistake because of this, and was almost hanged and beaten

After the optical axes of the two lens barrels are parallel.

Xu Yun turned the tripod and came to the final focusing stage.

Ding--

Bang——

Clang——

Gently gather, slowly twist, wipe and pick again.

Xu Yun is like an experienced old driver, slowly adjusting the telescope for the first time out of the factory.

In a quarter of an hour.

Xu Yun wiped the sweat from his forehead, stepped aside, and said to Old Su:

"My lord, luckily I did not disgrace my life."

Old Su nodded to him, walked to the eyepiece, and put his eyes on it.

The result is less than a moment.

Old Su raised his head from the eyepiece with a face full of horror, and pointed his index finger tremblingly at the field of view:

"Xiao Wang, that...is that the moon???"

Seeing this, Xiao Li on the side hurriedly came up:

"Uncle Su, what did you see?"

Old Su was silent for a moment, pointed to the eyepiece and said:

"Look for yourself, Xiao Wang has already adjusted the focus, just put your eyes on it."

Xiao Li glanced at Lao Li who was following him, and bounced to the eyepiece.

The result was the same as that of Old Su. After just a few glances, Xiao Li gasped:

"This is a lot of holes"

Then Xiao Zhao, Lao Li, Lao Jia, Wang Hou, and even Zhang Huaimin all stepped forward to take a look.

Although including Wang Hou and Zhang Shuye, everyone at the scene had seen another microscope before coming, so they were more or less familiar with certain situations.

But when they saw the gray, dead, and full of potholes in the field, they still couldn't help feeling a sense of horror.

There is no other reason.

Gein it's the moon!

well known.

In ancient China.

Due to the lack of sufficient and rich entertainment items, reciting poems has become a major pastime.

And in various poems.

The moon is undoubtedly a very common 'dragon'.

Whether it is "the sun and the moon, if they come out of it; if the stars and Han are shining, if they go out of them".

It's still "a toast to invite the bright moon, and the shadows become three people".

Or "the moon rises above the sea, and the world shares this moment", all of which are well-known masterpieces.

At the same time in myths and legends.

The moon is also Chang'e's residence. She steals elixir and flies to the moon. She raises a bunch of jade rabbits. She can eat spicy rabbit heads when she is free.

Although Lao Su doesn't believe in the theory of immortals and gods, he also has a relatively positive expectation for the moon.

The result was unexpected.

In the telescope, neither Tiangu Chang'e nor Yushu starlight can be seen.

The only thing that can be seen is gray soil and a lot of potholes.

And opposite him.

Seeing Lao Su with a horrified expression, Xu Yun rarely chose to remain silent.

For the ancients who came into contact with astral indications for the first time, fear, even panic, and fear were inevitable psychology.

Galileo, who was the first to observe the mare on earth, was actually the same.

After seeing the moon sea for the first time, he had a fever for two full days before accepting this fact, and then continued to observe the crater.

This is a hurdle that must be passed independently, and external help does not make much sense.

Earlier, Xu Yun had instilled a lot of knowledge about the universe into Old Su. If Old Su couldn't figure it out like this, then there was really nothing to say.

that's all.

The scene suddenly fell into a strange silence, and the donkeys who were eating grass at the side fell silent, looking at the Twolegs not far away in surprise.

A few minutes later.

Old Su took a deep breath first, and slowly closed his eyes.

When they opened and closed again, their eyes were already full of determination.

"Xiao Wang, the moon is not, or the moon, although it is far from what the old man thought, but it also solved one of the old man's concerns, and it also proves that the concept of 'planet' you mentioned is correct."

Old Su Jian said that he was silent for a moment, then turned to look at Zhang Huaimin, and said:

"Hey, just write it down."

"On the night of August 3rd in the third year of Yuanfu, Prince Taibao Su Song, Nan Keke, doorman Wang Lin, Xihe Jinglue appease Wang Hou, Zhongshi doctor Li Gefei and his daughter Li Qingzhao, and... Jian Wang Zhaosi, Mr. Tongyu Twenty-three people, including Jia Xian, took a first look at the ice wheel with the help of the 'Tiangong' telescope at Xiaolianzi Mountain outside Bianjing City."

"See you."

"There are countless depressions, the soil is gray, waterless, and uninhabited. It is as quiet as a ruin, and its shape is like an egg, standing upright"

Zhang Huaimin wrote them down one by one.

After saying these words, Lao Su's expression also relaxed.

Then he suddenly thought of something, and said to Xu Yun:

"Xiao Wang, more than forty years ago, there was a guest star that came out of the east in the morning, and remained there after nightfall. It was as bright as day.

In May of the first year of Hehe, Ji Chou was a few inches southeast of Tianguan, and it took more than 20 days for it to disappear.

At that time, the old man was working in the Tongzhi Taichang Liyuan, and once saw the guest star across the sky, even overshadowing Taibai at one point.

Do you know what this star is called? "

Xu Yun blinked:

"Forty years ago?"

Now it is 1100 AD, and it was about 1055 years ago more than 40 years ago.

And at that point in time.

There was indeed an extremely spectacular astrological phenomenon.

That is.

"The supernova explosion that created the Crab Nebula!"
