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 of them arrived outside the study courtyard, and Yongzhu stopped consciously:
"Brother Wang, the master and His Royal 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, but 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 microscopes.
The generators, electrolytic cells and other equipment previously made by Xu Yun have also been moved here, giving it a more or less technological style.
When Xu Yun entered the courtyard.
Xiao Zhao, who had not seen each other for a few days, was sitting with Xiao Li and Lao Su in the shade of a tree, chatting.
Seeing this, Xu Yun took the initiative to step forward, bowed his hands to King Jian, and said with a smile:
"Caomu Wanglin, I have 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.
This handsome man's mental state was much worse than when we first met him, with a faint worry in his brows.
It is clear.
Some changes in the palace brought a huge mental burden to this brother of Song Zhezong who was already under pressure.
Then King Jian raised his hand to Xu Yun again and said apologetically:
"Your Majesty, there was something going on in the Heavenly Palace a few days ago. It was inconvenient for me to go out. I have been 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 not in good health. As a descendant, Your Highness should be there to serve you. 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 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 still somewhat lacking.
Therefore, compared with "loyalty", the Song Dynasty court focused more on filial piety, and 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 Prince Jian, may I ask how the Queen Mother's Phoenix Body 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 now awake, 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 say anything, the action itself was an answer.
It is clear.
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 was something Xiao Zhao didn't say:
According to the information he received from a close confidant of the imperial physician, there was a high probability that Queen Mother Xiang would not last more than three months.
Once Empress Dowager Xiang dies, Zhao Ji will have no 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 still 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 hard work, Xiao Zhao's mental state became visibly depressed.
The only thing that Xiao Zhao can comfort himself now is that Zhao Ji was born with a soft (breast an) and (breast o) nature, and he has not done much to kill him since he came to the throne.
In addition, he and he were half-brothers, so Zhao Ji treated his mother Zhu very well and often went to pay her respects.
Therefore, under the premise that he has obviously given in, the most Zhao Ji can do is cut some of the 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 body has been completed. The mirror surface will be slower. It will take more than twenty days to complete."
Mentioned before.
The telescope designed by Xu Yun is close to one meter in diameter and about ten meters in length.
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 rotation 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 using 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 like a large sling.
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 your 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 is at least not as bad as using wood for the telescope. Xu Yun's telescope is made of iron.
Again, to answer another question from 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 third year of Xining's reign in the Song Dynasty, the imperial court set up 26 money-making offices 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, which is equivalent to about 15.3 kilograms, which is 13,000 tons based on 850,000 guan. (Paper doi: 10.13850/j.nki.hinum.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 deliberately pretended libertine character.
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:
"Young Master Wang, I met Mr. Xiaowei on the way to the courtyard. I heard that these days..."
"You made some good wine?"

Can some readers not be so smart? Input method questions sometimes change 'him' to 'she'. As a result, some people speculated that I was threatened by a female puncher and then gave in? Question mark for black people
