New Shun 1730

Tian Zhenyi's letter looked at the problem from a perspective similar to "palace fighting".

Women's thoughts and perspectives are always different from men's.

But after reading it, Liu Yu felt that this perspective seemed interesting. Thinking carefully, it seemed to be true.

The emperor did knock him once before, but the knock after pacifying the Western Regions was too light, just like patting his head and pinching his nose.

Tian Zhenyi used a strange metaphor, as if to say that the emperor "was too deep into the play, and really regarded himself as Han Wu and Tang Zong", so he was too deep into the play and regarded Liu Yu as Huo Qubing.

Huo Qubing died too early. After the Dashun "Xiongnu" was pacified, if "Huo Qubing" was still alive, what would his position be?

If you want to do great things in Nanyang, then be an orthodox noble. If you want to make internal changes, then be a qualified adviser.

Things that need to be done can be done quietly, but don't say them; for those things that must be said, don't express your opinion, just tell the emperor the pros and cons and let the emperor "make a holy judgment", without expressing support or opposition.

This letter has too much "feminine" flavor. This is not "personnel affairs are politics", but "human feelings are politics".

Let Liu Yu seize the buffer period of these years and complete the "image transformation" in the emperor's mind, which makes Liu Yu have to think more.

The following letters are all some interesting things in the capital and the family affairs of Duke Qi after returning from Luosha. The words are filled with the joy of a little girl. Duke Qi seems to have expressed his support for the marriage of the two intentionally or unintentionally, at least not opposed.

But at the end of the letter, it should be that Tian Zhenyi suddenly remembered something and carefully instructed another thing.

"Third brother, I almost forgot. As Mr. Kang said, the management of the Yellow River and the Huai River is all ready, except for the east wind."

"This all ready naturally includes the management plan of the Huai River after the canal transportation is abandoned in the future."

"But, never, never, never, never send people from the Jinghai Palace who have studied practical science and mathematics to search, research, investigate, or even find someone to make a plan. If you want to make a plan, your majesty must also arrange people to do it."

The letter stopped here, and there was no more. The last paragraph was also written with great force, which was completely different from the happy woman's mind in the previous one.

He burned the letter clean with a fire, rubbed his head, and tore up the memorial he had prepared.

He should no longer need to express his attitude of supporting sea transportation. As Kang Budai said, the success of this sea transportation has tied him to the sea transportation faction.

What Tian Zhenyi and Kang Budai said made sense, so why not compromise.

This time, Tan Zhen wanted to take the opportunity of the successful trial of sea transport to make a memorial to discuss the abolition of the canal and the change to the sea, but now it seems that the time is not right.

He can only continue to wait. The more he talks at this time, the more trouble will happen in the future, and it will be like slapping the emperor in the face.

The emperor's face may be more important to the emperor than hundreds of thousands of people.

Thinking that Tan Zhen may not be using him as a gun, he can only use a method that Tan Zhen may not like to cooperate with the ideas of the sea transport faction.

…………

When the winter month arrived, there were many things this year, and the governors of various places had to come to Beijing.

Liu Yu brought Lian Huaiguan, who had been visiting Songjiang for a while, to Beijing. Batavia had no snow and had never seen snow. Lian Huaiguan seemed very excited when he saw the scene of snowflakes for the first time.

The brothers who followed him were all shivering. The carriage with glass windows was not for them to ride, and these people who grew up in Batavia could not ride horses.

He was dressed like a bear, wrapped in cotton clothes, and shivered all the way to the capital.

Liu Yu's Earl's Mansion had not been built yet, but fortunately he had no shortage of accommodation in the capital. After arranging these people, he went to the capital to inquire about the news.

Knowing that North Korea had also sent tribute envoys this year, it seemed that North Korea had a lot of objections to the Celestial Empire's desire to lease some land.

After settling down, Liu Yu met the people he should meet and went to his uncle's house. His cousin Dang Xuanming did not stay in Europe, but returned with the delegation.

His uncle, who had been working on the reform of the land system in the southwest, also came back. After the visit, his cousin Dang Xuanming also knew Liu Yu's purpose and brought out a thick pile of books.

When he left, he still called him "Shou Chang"; when he came back, Liu Yu had already been conferred a title. Even at home, he still called him by his official name first. After Liu Yu politely said that you and I were cousins, there was no need to do this, and then he called him by his courtesy name.

Dang Xuanming's room had been installed with glass, which was wiped very brightly by the servants. The wind and snow outside were blocked by the glass, but they could not block the sun. It was noon and the sun was warm.

These glasses were presented to the emperor by Liu Yu a few years ago, and the emperor rewarded the ministers.

Driven by the palace and ministers, the capital has been in a trend of replacing glass in recent years. Of course, the main reason is that glass is cheaper.

It used to be a luxury, and officials were all honest, at least on the surface. Even if a piece of glass cost fifteen or sixteen taels of silver, it was affordable, but it was too ostentatious: in the palace, only a few places where the emperor read books were equipped with glass. If all the windows in his house were replaced with glass, it would be a bit too blind.

Nowadays, even before glass leaves the factory, taxes are collected, and the price is still affordable for the rich in the capital. From a luxury to a daily necessity, no one would choose the black window paper compared to glass.

Dang Xuanming didn't think anything of it. This time he followed Qi Guogong to Europe. They stayed together for several years and stayed for a long time. He saw a lot of things like glass windows.

"Shou Chang, I brought you all the books you asked for. There are also some things in the Duke of Qi's mansion. I can't understand the "British Star Catalog" and "Southern Hemisphere Star Catalog" either. It's just that. You asked me deliberately when you left, and I dare not forget this.”

I found the two books that Liu Yu had carefully warned me about before leaving from a pile of books, and handed them to Liu Yu. Liu Yu glanced at the name and made sure it was what he wanted.

"Fourth brother, thank you for your hard work. These two books are so important. Well, when I asked you to send me gifts and letters, did those people from the Rakshasa Academy of Sciences reply to my letter?"

Dang Xuanming nodded.

"Not with me, but with the Duke of Qi. He knows that what you do will be of great use. When he was in the Rakshasa Kingdom, he sent people to visit him and gave him gifts. By the way, when he was in Paris, someone also Ask me to bring back a book. It seems that his son is an academician of the Rakshasa Academy of Sciences, and he is not from a small country in Switzerland."

When talking about Switzerland, it was in Latin, and he didn't know how to translate it.

He dug out a "Tutorial on Integral Calculus" written by John Bernoulli of the Bernoulli family. Looking at the name on it, Liu Yu couldn't help but think of that famous transaction.

Lópida spent money to buy "Lópida's Law" from Bernoulli. With the gold coins, he can become famous in the history of science and become Lópida's Law that future generations of college students must learn. This business is really profitable.

Dang Xuanming smiled and said: "This man is quite interesting. Before we went to Rakshasa, didn't His Majesty give a warning to the young people in the Rakshasa mission? Some problems arose. This man came from his son After hearing about this, he sent a letter to Paris all the way and asked me to bring a letter. "

He gave the letter to Liu Yu, who opened it and read it. He couldn't help but laugh out loud, thinking that this person was indeed interesting.

There are only two contents in the letter.

First, he didn't believe that the fastest deceleration question was part of the Dashun general exam.

If such questions are part of the general examination in Dashun, then a lot of the research he has done seems to be meaningless repetition of work that has been done by others.

Furthermore, the letter repeatedly reiterated that Newton's theory of universal gravitation is wrong, and Descartes's ether vortex theory is the real reason for explaining the movement of celestial bodies. I hope Liu Yu will not continue to study Newton's theory, nor will he ignore Dashun's science. Take the wrong path.

This is not to say that he was doing evil in secret, but that this man really believed in Descartes's mechanical materialist ether vortex theory. For this reason, he often quarreled with Newton: he was a good friend of Leibniz. In order to criticize Newton, he spared no effort and even brought the British to criticize him. He can be said to be the king of trash talk in the mathematics world at this time.

The letter was written in Latin. Although Dang Xuanming recognized some words, he did not recognize some special proper nouns. There were a lot of strange symbols on it, which he was not interested in.

Just watching Liu Yu read the letter made him smile. He thought to himself that this is strange. If I showed those people the Tang poems and Song lyrics, how would they understand the inside? On the other hand, I couldn't understand the dramas they showed me.

But with these strange symbols, even though they were tens of thousands of miles apart, Shou Chang could still communicate with this person, and even have a conversation?

It seems that these should all be some knowledge like the sun rising from the east, regardless of Eastern learning or Western learning.

After Liu Yu finished reading the letter, Dang Xuanming pointed to the two star catalogs and said, "What are these two books for?"

"Hey, those things from Qin Tian Jian. Mainly because they are useful to me at sea. Since others have made them, I can use them as soon as I get them, which saves me the trouble of observing them myself. The main thing is this "Southern Hemisphere Star Catalog", let's think about it. It’s really difficult to get it out, so I pay special attention to it, no matter the cost.”

After a brief explanation, Dang Xuanming didn't quite understand.

Liu Yu also knew that although these two star catalogs were very important, until a genius solved the problem of the moon's orbit, he still couldn't look at the sky to know where he was.

Fortunately, Dang Xuanming said that Euler, whom he was concerned about, wrote a reply to him and it was in the hands of Duke Qi. Perhaps under his own influence, Euler could solve this lunar orbit problem earlier?

As long as Euler can solve the problem of the moon's orbit, he can organize people to take the lead in compiling an astronomical almanac. Dashun's navy can be half a head ahead of Britain on navigation issues: although marine clocks are good, they cannot be mass-produced, and Britain The current lead is not insurmountable.

After putting away these books, Liu Yu was most interested in what these people thought after returning from Europe.

When asked about this, Dang Xuanming couldn't help laughing.

"This Frenchman seems to have a hobby. He likes to show people how they attack cities."

Liu Yu also smiled and said: "Yes, it's an old tradition."

"Well, not long after we arrived in France, France started fighting with others. Your Majesty sent us there just to see how the Westerners fought. I thought that the French would not agree to military matters. How could I ever think that France would say anything about them? There has always been a tradition of inviting people to visit the besieged city.”

"This time we will attack a place called Philipsburg. It is said that France's former Marshal Vauban besieged it, and used your method of digging holes to advance. This time we will attack this place again, and this time the leader of the team will He is also a marshal. I heard that he is the illegitimate son of the British king and a woman named Churchill."

"It's very confusing. His uncle seems to be a British marshal, and he is a French marshal. Afterwards, the French said that Marshal Vauban attacked Phelpsburg and was familiar with the route. He also asked us to see the French siege methods, which was intended to show off their military power."

"The French often boasted to us that their ability to attack and besiege castles is unparalleled in the world."

Speaking of this, Dang Xuanming couldn't help laughing.

"As a result, this French marshal was unlucky. During the siege... Hahahaha, it just so happened that he was killed by the defenders' artillery. We only watched half of it, and the second half was all about watching the jokes of France."
