Han Dao world

Cai Yan suddenly laughed. "Aheng, the emperor's intelligence is beyond your imagination. The academic knowledge he has understood but has not published is not only the art of circumcision. You may not know that it was he who arranged Mrs. Tang's establishment of the printing bookstore. Mrs. Tang just obeyed the imperial edict. Just act."

Yuan Heng was taken aback.

If you want to comment on the most influential thing in ten years, it may not be the emperor's efforts to turn the tide, but the emergence of bookstores.

The bookstore made the original precious books readily available, and ordinary people could afford and buy books. On the one hand, it made academic dissemination easier. All men and women have become achievable fact.

With their academic and court bargaining advantages gone, the gentry had no choice but to take the initiative to cooperate with the court to avoid being abandoned or being driven to the Bohai Sea.

Everyone knows that the bookstore was created by Mrs. Tang, but no one knows that the real source is the emperor, and Mrs. Tang is just an executive figure in front of the stage.

Yuan Heng took another look at Cai Yan. "So, the Son of Heaven hopes that my sister will become an academic Mrs. Tang, and in the name of my sister, he will benefit the world with his strategies?"

Cai Yan was thoughtful, but forgot to answer for a while.

Chapter 1106 Circle Cutting Technique

A few days later, Cai Yan came to the bookstore with two manuscripts.

Mrs. Tang had just finished her work and was taking a break to drink tea in the hall, when she saw Cai Yan walking in with a happy face, she couldn't help but chuckled.

"Ling Shi is in a good mood."

Cai Yan was taken aback for a moment, then touched his face guiltily. "Is there?"

Mrs. Tang smiled without saying a word, looking at the manuscript in Cai Yan's hand. "What, want to post an article?"

Cai Yan took advantage of the situation and said, "Yes, I just wrote two articles and wanted to publish them in the mansion newspaper for discussion. I thought I hadn't seen you for a long time, so I went to see you."

"It's not easy to make you Cai Lingshi go away. I have to treat you well." Mrs. Tang asked while pouring tea herself: "What kind of article is it? Do you want to invite the reviewers to offer wine?" come over?"

"Just invite Xu Gonghe to come." Cai Yan said: "These articles are the emperor's painstaking efforts. I want to explain to them face to face."

Mrs. Tang's eyes flashed, but she didn't say anything. She asked her personal maid to invite Xu Yue, and arranged for someone to prepare lunch.When the maid went out and there were only the two of them left in the yard, Mrs. Tang said with a smile:

"Should I change my mouth?"

Cai Yan shook his head and smiled back. "Not so fast."

Madam Tang clapped her hands and smiled. "Nevertheless, I still want to congratulate you. After waiting for several years, I finally got what I wanted and lived up to this life. Zhaoji, I'm not talking about you, you just read too much and are too reserved. If you listen to me, Didn't it happen in the first place?"

Cai Yan smiled and lowered his head.

When she was still in Huayin, Mrs. Tang suggested that she take the initiative to show her favor to the emperor, but she couldn't afford to lose face, so she wasted a few years in vain.If he could have listened to Mrs. Tang at that time and took the initiative, he might be a legitimate nobleman now, and even have a prince and daughter.

"Anyway, this is a good result." Mrs. Tang said again: "It's just that you are not young, so you should hurry up. After giving birth to a son and a half, you will have someone to rely on in the future."

Cai Yan nodded, and just as he was about to speak, Xu Yue strode in and shouted excitedly, "Is there any good article in Lingshi? Is it your father's posthumous work, or is it a new poem?"

Cai Yan exchanged glances with Mrs. Tang, and said with a smile, "Maybe I'm going to disappoint Jijiu, but it's not, it's a small article related to glass mirrors."

"Really?" Xu Yue was a little surprised.

Although he was invited to review, the general overview would be practical studies, but he knew that Cai Yan's research mostly focused on literature and history, and did not pay much attention to practical studies.

Cai Yan took out the article and asked Xu Yue to read it.

Xu Yue didn't sit down either, so he stood on the porch, looked it over quickly, and then praised: "Ling Shi is so thoughtful, this method is indeed something that many people have never thought of. It's just that..."

He frowned and turned to look at Cai Yan. "This circumference-to-diameter ratio is so accurate, how did you get it? Can you tell me the calculation technique?"

"Of course, it's in another article in the hands of the sacrificial wine."

Suddenly, Xu Yue quickly opened another piece of paper, and his eyes immediately brightened.

"Circle-cutting technique? This is good, this is good, it is more accurate than Zhang Pingzi's algorithm. With this technique, Ling Shi is enough to rank among the masters of mathematics, and will also have a place in the hall of fame in the future."

After hearing this, Mrs. Tang gave Cai Yan a surprised look.

Zhang Heng has been famous recently, but anyone who is interested in mathematics must pay homage to this master.Xu Yue is a master of arithmetic, he admired Zhang Heng, and he also has a deep understanding of Zhang Heng's academics.He said that Cai Yan's circle-cutting technique is more accurate than Zhang Heng's algorithm, and it is extremely heavy.

She knows that Cai Yan is talented and intelligent, and has a long history of family education, but he is smarter than Zhang Heng, which is a bit scary.

She immediately thought of Cai Yan's reminder just now, and realized that this circle-cutting technique was probably the result of the emperor, not just Cai Yan's.It's just that the emperor didn't want to show his face, so Cai Yan stepped forward.

It can be seen that the emperor's trust in Cai Yan is irreplaceable.

Of course, Cai Yan himself is irreplaceable.

Although there are many women around the emperor, as smart as Cai Yan, there are not many who can help the emperor academically, and it can even be said that there is no one more suitable than Cai Yan.

Cai Yan had a discussion with Xu Yue, first explaining the idea of ​​cutting the circle, and then began to explain the relevant analysis of transmission and reflection.

Xu Yue was most interested in the circle-cutting technique. He asked and asked again and again, but he didn't care too much about the transmission and reflection.

Mrs. Tang was silent for a moment, then sighed softly. "Sure enough, the Son of Heaven has great ambitions, and forgets personal interests in public affairs. Everything will benefit the country."

Cai Yan understood Madam Tang's implication as soon as she heard it, shook her head and said, "Ma'am, you are serious. These are two different things and should not be confused. Besides, if a man and a woman like each other, it is either for talent or for sex. Color is easy to fade but talent is inexhaustible." , It’s better to be talented than to be beautiful. Even if you don’t have these, it’s good to be able to use them.”

Madam Tang smiled. "Sister, it's best if you are satisfied."

"Thank you, madam. It is precisely because I know that madam cares for me that I take the liberty to tell you." Cai Yan paused, and then said: "The emperor has suffered many disasters, and he is responsible for his family and country, so he will inevitably have scruples in his actions. I hope he is like an ordinary boy. Showing joy and anger, it's hard to be strong. If I don't want to miss the opportunity, I have no choice but to put aside the reservedness of a woman and take the initiative."

"Sister is so courageous, I really admire her."

"Rather than looking for fish in the abyss, it's better to retreat and make a net. As a human, you have to fight for yourself."

Mrs. Tang just wanted to make fun of Cai Yan, but when she looked up, she saw Cai Yan looking at her with burning eyes, and she couldn't help being taken aback.Immediately after reacting, he couldn't help spitting, flicked the handkerchief, and stopped talking.

Shangfang Workshop.

Zhou Qun stood beside the steaming stove with his sleeves rolled up and his hips akimbo.

A ball of glazed material that was burning red was carefully poured into the mold and slowly leveled.So everyone held their breath, stared wide-eyed, and looked at the slowly cooling glazed material.

They improved the formula, removed some of the ingredients, improved the boiler, increased the temperature, and made the glass material easier to level.Whether a more transparent and uniform lens can be made depends on this time.

Watching the red light of the glass frit gradually dim, and the glass slowly reveal a clear stream like water, the corners of Zhou Qun's mouth involuntarily raised.The Shangfang officials on the side also became excited. Seeing this, there is a high probability that this time it will be successful.

After spending nearly a hundred gold, they finally saw the hope of success.

A young official approached. "Zhou Jun, have you read Cai Lingshi's latest article?"

"Cai Lingshi from Lantai? Not interested." Zhou Qun dismissively. "When our experiment is successful, we can ask her to write a great poem, which should be even better than General Han's great victory picture."

"It's not a poem." The officer said with a smile, "it's an article related to Liuli mirror."

Zhou Qun turned to look at the officials. "She still understands this?"

"Cai Lingshi is the son of heaven. He has read more classics from the Western Regions than anyone else. Most of the Western Regions articles we refer to now are translated by her." The official said, taking a copy of the residence newspaper and handing it To Zhou Qun.

Zhou Qun looked it over, tilted his head, thought for a while, then suddenly slapped his thigh, and shouted, "Wonderful, I'm so stupid, why didn't I think of this? I wasted so much time."

"Waste?" The officials at the side glanced at each other, thinking Zhou Qun's words were too unlucky.

It's so easy to see the hope of success, but you say it's a waste of time?

Zhou Qun ignored them, turned around and left. "I leave this matter to you. I'm going to study a better clairvoyance, so I won't play with you."

Chapter 1107 Military-civilian Combination

"What's going on?" Liu Xie narrowed his eyes, held up a crystal clear lens, and looked into the distance again and again, feeling joyful in his heart.

It was beyond his expectation that lenses that could satisfy military use were developed so quickly.

It was a good thing at first, but Taishi Ling and Fang Ling had conflicts, and they even got into a dispute in front of the imperial court.

Tai Shiling felt that Zhou Qun was responsible for the successful development of transparent glass, and it should not be counted because Zhou Qun voluntarily gave up.Zhou Qun is just a waiting edict of the Taishi Department, and cannot represent the Taishi Department, let alone the Taichang Temple.

Therefore, the credit that should be given to Taichang Temple must be given.

Shang Fangling believes that although Zhou Qun has made great efforts in the process of researching lenses, he has neither a good start nor a good end. He has not made any meaningful suggestions on the improvement of the formula or the transformation of the blast furnace. The merits are not to the point of dividing the merits. At most, he will be invited to the celebration banquet at that time.

In the final analysis, the reason is that Zhou Qun suddenly dropped the pick when he was done.

Because they all know that in order to develop lenses that can meet the requirements, the emperor spared no expense, and the rewards after success must be heavy.For the officials who have worked hard for several months, this is a reward that cannot be given up.

Therefore, none of them are willing to give in easily.

"What did Zhou Qun do?" Liu Xie put down his glasses and asked calmly.

Tai Shiling answered first. "Return to Your Majesty, Zhou Qun is developing a new telescope that can eliminate chromatic aberration."

Liu Xie understood after a little thought.

Zhou Qun wanted to watch the stars, and a lens with a small magnification could not meet his requirements, and the problem of chromatic aberration was one of the obstacles to the magnification of the lens.This problem cannot be solved by adjusting the formula, but by finding another way.

Is he trying to use a reflector?

According to Shang Fangling, Zhou Qun gave up the credit because he saw Cai Yan's article, and Cai Yan's article just talked about the problem of reflection.Although he did not mention surface reflection, Zhou Qun has been paying attention to this issue for a long time, and it is understandable to think that curved surfaces can be enlarged.

But the production of curved mirrors is also very difficult. Zhou Qun thought things were too simple.

"He has research on chromatic aberration?"

"He has been studying the problem of chromatic aberration, and even thinks that the star change that Yang Xiu mentioned may be caused by chromatic aberration, not the actual situation."

Liu Xie was surprised. "Are there any articles published?"

He has always had doubts about Yang Xiu's experience, but he doesn't have a suitable telescope to verify it.Now that I heard that Zhou Qun was also questioning this question, I immediately fell in love.

He was not afraid of Yang Xiu's mistakes—science is about constantly questioning and correcting mistakes—but he wanted to know what Zhou Qun suddenly discovered.

Tai Shiling said: "No article has been published yet. Zhou Qun is so absorbed in blueprint design that he hardly has time to write articles."

Shang Fangling pouted. "If you don't write it, you don't write it. What does it have to do with the blueprint design? Cai Lingshi is busier than him, so there are articles published?"

Seeing that Tai Shiling was about to roll up his sleeves again, Liu Xie quickly stopped them. "No matter what new equipment Zhou Qun wants to use, Supervisor Shang Fang will help make it in the future. You'd better be polite."

Tai Shiling was taken aback for a moment, and then felt embarrassed. "Your Majesty is right, it is the minister who is presumptuous."

Supervisor Shangfang snorted triumphantly.

The successful development of a clearer lens is only the first step. The Taishi Bureau wants to make a telescope that can be used for astronomical observations, and Shangfang Supervisor is required to make a bigger and better telescope.

On this point, Supervisor Shangfang is full of confidence and is very confident.

It should be said that he has never been so tough since he joined the job.With the strong support of the emperor, these craftsmen who have always been despised by others finally feel proud.

Liu Xie comforted Taishi Ling and asked him to pass on Zhou Qun, so as to confirm the progress of Zhou Qun's research.At the same time, he reassured Tai Shiling that no matter what Zhou Qun thought, Zhou Qun's contribution would definitely be taken into consideration when rewarding him, and he would not let him do it for nothing.

Tai Shi left with satisfaction.

Liu Xie immediately ordered Shang Fangling to sort out the relevant information on the one hand, and to speed up the trial production of several telescopes for testing on the other hand.The successful development of lens materials is only the first step, and the combination of different lenses is also very important. Only a qualified telescope can be considered a real success, and it is too early to strive for success.

Supervisor Shangfang also left happily.

Liu Xie played with the lens, thought for a while, then called Yuan Heng, added a few comments, and sent her to Shangfang Prison.

First, it is necessary to strengthen the awareness of confidentiality, and there is no need to rush to publish relevant results.Especially when it comes to military telescopes, relevant details cannot be leaked.

Second, prepare to hold a conference on the results of the materials, look for potential business partners, and realize the results.

In order to develop a more transparent colored glaze, he has spent nearly a hundred gold, and urgently needs blood recovery in order to maintain further development.The demand for military binoculars is limited, and it will definitely not be able to pay back. Only civilian use can realize profitability.

The current material properties can already be used to make reading glasses, and it is not a problem to make lenses for making fire, and it can be pushed to the civilian market.

The number of craftsmen in Shangfangjian is limited, and the work of civilian use can only be handed over to folk workshops.

Third, cooperate with the Imperial Medical Administration to develop microscopes.

Just as Yuan Heng left for a while, Zhou Qun rushed over, with a roll of drawings under his stomach, and ink stains all over his cuffs.As soon as they met, they hurriedly saluted and spread the drawings in front of Liu Xie.

"Your Majesty, this is the result of my minister."

Liu Xie took a look, and as expected, it turned out to be a reflector.

He didn't say anything, and listened patiently to Zhou Qun explaining his idea.For him, real wisdom is the thinking method embodied in the process of discovering and solving problems, and the final result is not important.

As long as the idea is right, after continuous iteration, the finished product will always get better and better.

If you don't pay attention to the process and only focus on the result, it's better for him to give them that knowledge directly.

But so what?They still know it, but they don't know why.What he gave, it will still be what it is a hundred years later, there will not be much progress.

Seeing that Liu Xie was listening seriously, Zhou Qun was even more excited when he spoke, with a pile of foam on the corner of his mouth.

After Zhou Qun finished speaking, Liu Xie encouraged him to find a way to complete the trial production of the product as soon as possible.After all, a theory is just a theory, and only when it is made into a real thing can we know whether the theory is feasible.

Zhou Qun was a little annoyed. "The minister is about to ask His Majesty to make the decision, but Shang Fangjian refuses to cooperate."

"Is it too busy, or can't understand your design, and don't want to waste time and energy?"
