Chapter 151 Goodbye Xiao Zhao
"His Royal Highness King Jian?"
Hearing Yongzhu's words, Xu Yun suddenly looked shocked.
Good guy.
Is Xiao Zhao leaving the palace?
After realizing this, he quickly put the memo away.
After tidying up his clothes, he went out and followed Yongzhu to the courtyard where the study was located.
Half an hour later.
The two came outside the study courtyard, and Yongzhu stopped consciously:
"Brother Wang, the master and His Highness Prince Jian are both in the courtyard. The master has told you that there is no need to inform you when you arrive, just go in directly."
Xu Yun thanked him, turned around and walked into the courtyard.
With the recent completion of the preparation of microscopes, 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 previously made by Xu Yun have also been moved here, and they have a certain technological style.
When Xu Yun entered the courtyard.
Xiao Zhao, whom he hadn't seen for a few days, was sitting in the shade of a tree chatting with Xiao Li and Lao Su.
Seeing this, Xu Yun took the initiative to step forward, bowed his hands to King Jian, and said with a smile:
"Wang Lin, a grass-roots citizen, has met His Royal Highness King Jian."
Xiao Zhao was sitting facing the entrance, so he didn't react until Xu Yun was close, and he quickly smiled at Xu Yun:
"My lord, long time no see."
Xu Yun said hello to Lao Su and Xiao Li again, and at the same time took advantage of the gap between raising his head and turning his head to quickly look at Xiao Zhao.
Not seen for two weeks.
The handsome man's mental state was much worse than when we first met him, and there was a hint of sadness in his brows.
It's obvious.
Some changes in the palace brought a huge mental burden to this brother of Song Zhezong, who was already under pressure.
Then King Jian bowed his hand towards Xu Yun again and said apologetically:
"Your Majesty, something happened in the palace a few days ago. It is inconvenient for me to go out. I will be absent for more than five days. Please forgive me, Your Majesty."
Xu Yun was still thinking about what to say. Seeing Xiao Zhao taking such initiative, he quickly returned the salute and said:
"The Queen Mother is in poor health. As a descendant, Your Highness should be at your service. Filial piety and brotherhood are the principles of human relations. How can you apologize?"
Lao Su and Xiao Li on the side heard this and nodded in agreement.
Throughout China's five thousand years of history.
The two words of loyalty and filial piety are the core values of human ethics that are mentioned repeatedly in almost every dynasty.
The throne of the Song Dynasty originated from Zhao Kuangyin's mutiny, and was taken from the hands of Emperor Zhou Gong and his orphans and widowed mothers. No matter how the subsequent generations of Song emperors tried to clear their names, their confidence was somewhat lacking.
Therefore, compared with "loyalty", the Song Dynasty court focused more on filial piety. The development of filial piety culture was historically ranked high.
Therefore, when faced with Xu Yun's answer, even Xiao Li, who was relatively unconventional, seemed to agree very much.
at the same time.
Old Su followed these words and asked Xiao Zhao about the situation in the palace. After all, Xiao Zhao had just arrived and he did not have time to inquire about the inside story in detail:
"Your Highness King Jian, may I ask how the Queen Mother Phoenix is doing now?"
Xiao Zhao was silent for a moment after hearing this, and his face turned a little gray:
"Although the Queen Mother is awake now, her body is still in poor condition. She has to stay in bed for nearly ten hours every day. The situation is not optimistic."
Old Su looked at him thoughtfully and asked again:
"What did the imperial doctor say?"
Xiao Zhao slowly exhaled a breath and shook his head.
Although he didn't speak, the action itself was an answer.
It's obvious.
As a junior and a stakeholder, Xiao Zhao cannot be too straightforward in some aspects, but the imperial doctor obviously gave some bad judgments.
Although Empress Dowager Xiang was successfully rescued this time, what about next time?
No one can guarantee it.
Actually.
There is something Xiao Zhao did not say:
According to the information he received from a close confidant of the imperial physician, Queen Mother Xiang would most likely not survive three months.
Once Empress Dowager Xiang dies, Zhao Ji will no longer have any constraints, and he may be in trouble.
Therefore, in the past few days, Xiao Zhao has been busier than the imperial doctor.
In addition to serving the Queen Mother.
He also has to think about his next choice, and at the same time he will inevitably come into contact with Zhao Ji every day.
After all the troubles, Xiao Zhao's mental state became visibly depressed.
Now the only thing Xiao Zhao can comfort himself is that Zhao Ji is naturally soft (ruan) and (ruo), and he has not done much killing since he took the throne.
In addition, he and he are half-brothers, so Zhao Ji treats his mother Zhu very well and often goes to pay her respects.
Therefore, under the premise that he has obviously given in, the most Zhao Ji can do is cut some fees and spread some weird rumors, and he should not be cruel to himself.
Bar?
Think of this.
Xiao Zhao couldn't help but sigh slightly, put these thoughts aside for the time being, and asked Xu Yun:
"Master Wang, I wonder how the production of the telescope is progressing?"
Xu Yun pondered for a moment and replied:
"Back to Your Highness, one-fifth of the barrel has been completed. The mirror will be slower. It will take more than twenty days to complete."
Mentioned before.
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 this pair of bases?"
But actually.
The requirements for the base of an astronomical telescope are not as high as imagined.
Even in later generations, the core of an ordinary telescope base was just a Dobson base plus a center sag, which was mainly used to track the field spins of celestial bodies.
Many vehicle-mounted telescopes built by astronomical enthusiasts in later generations are not equipped with Busen bases above 0.5v. The method of placing a cushion on one side of the high base can barely achieve this effect.
Another example is in the 18th century.
The astronomical telescope made by Hershel that mapped the structure of the Milky Way was basically mounted on a wooden cart, somewhat similar to a large catapult.
The specifications of that telescope are 1.22 meters in diameter and 12.4 meters in length, which is larger than Xu Yun's.
Modern productivity levels are high, and requirements in all aspects will naturally pursue refinement.
However, the level of academic development in ancient times was relatively limited, so it is not necessary to look at ancient times from a modern perspective.
Just like participating in the 800-meter run in high school, if my level is not high, is it necessary to wear sneakers worth 150,000 yuan?
Take the global level of scientific understanding in the Song Dynasty or the 11th century.
Too advanced knowledge will harm them. This is a problem of the limitations of the times.
Of course.
Compared to that poor fellow Hershel, Xu Yun's telescope was at least not as bad as using wood as the barrel - Xu Yun used iron.
Again, another question in response to the reader who asked about the pedestal.
The volume of a hollow cylinder with a diameter of 1 meter, a length of 10 meters and a thickness of 2 centimeters is 0.61544 cubic meters. The weight of one cubic meter of iron is 7.8 tons.
By doing basic multiplication, we can conclude that the iron consumed in making a telescope is about five tons.
The Song Dynasty was the dynasty when Chinese stir-fry dishes officially began to become popular among the common people. The core reason was because of the high iron output in the Song Dynasty.
Give me a chestnut.
Starting from 1069, the 3rd year of Xining in the Song Dynasty, the imperial court set up 26 money-making prisons across the country, with more than 5 million copper coins and more than 800,000 iron coins minted every year.
The iron coins cast in the Song Dynasty were usually large iron coins weighing 25.5 Song Jin, equivalent to about 15.3 kilograms, which was 13,000 tons based on 850,000 coins. (Paper doi: 10.13850/j.cnki.chinum.2005.04.010)
Therefore, not to mention Xiao Zhao, Lao Su could collect more than five tons of iron without much effort.
His gaze returned to its original position.
After learning about the progress of the telescope from Xu Yun downstairs, Xiao Zhao's eyes suddenly filled with joy and expectation.
It is different from the persona of a libertine who deliberately pretends to be a libertine.
He really liked the science put forward by Xu Yun from the bottom of his heart.
For example, before Xu Yun arrived, he took Xiao Li to experience a high-precision microscope, and what he observed was Brother Donkey's tadpoles.
However, he is somewhat similar to Lao Su. Compared with microorganisms and cells, he is more interested in the sky that can be seen when looking up.
Then Xiao Zhao thought for a while and asked Xu Yun:
"Master Wang, I met Mr. Xiaowei on the way to the courtyard. I heard that these days"
"You made some good wine?"(End of Chapter)
