Into Unscientific

"His Royal Highness Jane?"

Hearing Yongzhu's words, Xu Yun's expression was shocked.

Good guy.

Xiao Zhao is out of the palace?

After realizing this, he quickly put away the memo.

After tidying up his clothes, he went out and followed Yong Zhu to the courtyard where the study was located.

After half a quarter of an hour.

The two came to the outside of the study courtyard, and Yong Zhu stopped consciously:

"Brother Wang, the master and His Royal Highness Jian Wang are both in the courtyard. The master has told you that you don't need to report when you arrive, and you can just go in."

Xu Yun thanked him, turned around and walked into the courtyard.

With the preparation of the microscope not long ago, the nature of this academy is no longer just a collection of books, it has become a quasi-scientific research place,

Xiao Li and Lao Su basically come here to do experiments and so on whenever they have free time.

Except for the microscope.

The generators, electrolytic cells and other equipment that Xu Yun made before have also been moved here, which more or less has a certain technical style of painting.

When Xu Yun entered the courtyard.

Xiao Zhao, who hadn't seen him for a few days, was sitting under the shade of a tree with Xiao Li and Lao Su, chatting.

Seeing this, Xu Yun took the initiative to step forward, cupped his hands at King Jian, and said with a smile:

"Grassman Wang Lin, I have met His Royal Highness Jian Wang."

Xiao Zhao was sitting sideways to the entrance, so he didn't realize it until Xu Yun got close, and quickly smiled at Xu Yun:

"Prince, long time no see."

Xu Yun greeted Lao Su and Xiao Li again, and at the same time, taking advantage of the gap between raising and turning his head, he quickly looked at Xiao Zhao.

Not seen for two weeks.

The mental state of this handsome man is much worse than when he first met, and there is a faint worry between his brows.

It is clear.

Some changes in the palace brought a great mental burden to Song Zhezong's younger brother who was already under pressure.

Then King Jian arched his hands towards Xu Yun again, and said apologetically:

"My lord, there was something in the Heavenly Palace a few days ago, and it is inconvenient for me to go out. I have been absent for more than five festivals. Please forgive me, my lord."

Xu Yun was still thinking about the topic, but seeing Xiao Zhao taking the initiative, he quickly returned the salute and said:

"The Empress Dowager is in poor health. As a junior, Your Highness should serve by her side. Filial piety is the way of human relations. How can I apologize?"

Old Su and Xiao Li at the side nodded in agreement when they heard the words.

Throughout the 5,000-year history of China.

The two characters of loyalty and filial piety are the core human ethics that are repeatedly mentioned in almost every dynasty.

The throne of the Song Dynasty originated from Zhao Kuangyin's mutiny, which was taken from Emperor Zhou Gong and his orphans and widows.

Therefore, compared with "loyalty", the court of the Song Dynasty will put more emphasis on filial piety, and the degree of development of filial piety culture is ranked first in history.

Therefore, facing Xu Yun's answer, even Xiao Li, who was relatively out of touch, seemed to agree very much.

at the same time.

Following these words, Old Su asked Xiao Zhao about the situation in the palace. After all, Xiao Zhao had not been here for long, and he didn't have time to inquire about the inside story in detail:

"His Royal Highness, may I ask the Queen Mother Feng Ti is well?"

Xiao Zhao was silent for a moment when he heard this, his face darkened slightly:

"Although the Empress Dowager is now awake, her phoenix body is still not in good condition. She has to lie on the couch for nearly ten hours a day. The situation is not optimistic."

Old Su looked at him thoughtfully, and asked again:

"What did the doctor say?"

Xiao Zhao exhaled slowly and shook his head.

Although he didn't speak, this action itself was an answer.

It is clear.

As a junior and a stakeholder, Xiao Zhao can't be too straightforward in some aspects, but the imperial physician obviously gave some bad judgments.

Although the queen mother was successfully rescued this time, what about next time?

No one can be sure.

Actually.

Xiao Zhao did not say a word:

According to the information he got from a trusted imperial physician, there was a high probability that the Queen Mother would not survive for three months.

Once the Empress Dowager passed away, Zhao Ji would be in trouble, and Zhao Ji would be in trouble.

Therefore, in the past few days, Xiao Zhao was busier than the imperial physician.

In addition to serving the Queen Mother.

He still has to think about his next choice, and at the same time, he will inevitably have contact with Zhao Ji every day.

After a lot of tossing, Xiao Zhao's mental state was visibly weakened by the naked eye.

The only thing Xiao Zhao can comfort himself now is that Zhao Ji is soft (ruan) and (ruo) by nature, and he has not been too aggressive since he took the throne.

In addition, he and himself are half-brothers, and Zhao Ji treats his mother Zhu Shi pretty well, and often goes to pay her respects.

Therefore, on the premise that he obviously backed down, Zhao Ji would at most cut some money and spread some rumors of yin and yang, so he should not be cruel to himself.

Bar?

Think here.

Xiao Zhao couldn't help but sighed slightly, put aside these thoughts for the time being, and asked Xu Yun:

"My lord, I don't know how the progress of the telescope is made?"

Xu Yun pondered for a moment, then replied:

"Returning to Your Highness, one-fifth of the cylinder body has been completed, and the mirror surface needs to be slowed down. It will take about 20 more days to complete."

Mentioned earlier.

The telescope designed by Xu Yun has a diameter of nearly one meter and a length of about ten meters.

It's a coincidence.

When Xu Yun was writing novels in his previous life, he also wrote about telescopes with similar specifications. At that time, some readers asked, "Do you know the accuracy requirements for the base?"

But actually.

The requirements for the base of the astronomical telescope are not as high as imagined.

Even in later generations, the core of the base of an ordinary telescope is only the Dobson base plus a sag, which is mainly used to track the field rotation of celestial bodies.

Many car-mounted telescopes made by astronomy enthusiasts in later generations are not equipped with a Busson base with a value above 0.5v, and the method of relying on the side of the base to raise the base can barely achieve this effect.

Or in the 18th century.

The astronomical telescope made by Herschel, which drew the structure of the Milky Way, was basically mounted on a wooden cart, and it was somewhat similar to a large catapult.

The size of that telescope is 1.22 meters in diameter and 12.4 meters in length, which is bigger than Xu Yun's.

With the high level of modern productivity, the requirements of all aspects will naturally pursue refinement.

However, the development level of ancient disciplines is relatively limited, and it is not necessary to demand ancient times from a modern perspective.

Just like participating in a high school 800-meter run, the level of the platform itself is not high. Is it necessary to wear 150,000 sneakers?

Take the global level of scientific cognition in the Song Dynasty or the 11th century.

Too advanced knowledge will harm them instead, which belongs to the limitations of the times.

Of course.

Compared to Heschel's poor guy, Xu Yun's telescope is at least not so miserable that they use wood as the lens barrel - Xu Yun uses iron.

Again, another question for the reader who asked the pedestal question.

A hollow cylinder with a diameter of 1 meter, a length of ten meters, and a thickness of 2 cm has a volume of 0.61544 cubic meters, and a cubic meter of iron weighs 7.8 tons.

Doing a basic multiplication, it can be concluded that the iron consumed to make a telescope is about five tons.

The Song Dynasty was the dynasty in which Huaxia cooking officially began to spread to the common people. The core reason was that the Song Dynasty produced a lot of iron.

Take a chestnut.

In the 3rd year of Song Xining. That is, since 1069, the imperial court has set up 26 coin casting supervisors all over the country, casting more than 5 million copper coins and more than 800,000 iron coins annually.

The cast iron coins in the Song Dynasty were 25.5 Song Jin, or about 15.3 kilograms of large iron coins, which was 13,000 tons based on 850,000 Guan. (paper doi: 10.13850/j.cnki.chinum.2005.04.010)

So more than five tons of iron, not to mention Xiao Zhao, Lao Su can get together without much effort.

The line of sight returns to the original place.

After learning about the progress of the telescope from Xu Yun downstairs, Xiao Zhao's eyes were filled with joy and anticipation.

It's different from the deliberately pretended libertine character.

He really liked Xu Yun's theory of science from the bottom of his heart.

For example, before Xu Yun arrived, he took Xiao Li to experience a high-precision microscope, observing the little tadpoles of the donkey brother.

However, he is somewhat similar to Old Su. Compared with microorganisms and cells, he is more interested in the sky that can be seen from above.

Then Xiao Zhao thought about it, and asked Xu Yun again:

"My lord, on the way to the yard, I met Mr. Captain, I heard that these days"

"You made some good wine?"
