This year's capital, the Chinese New Year is quieter than in previous years. Without fireworks, people cannot celebrate it, but only sacrifices and reunion. However, it can be expected that the Lantern Festival will be unprecedentedly lively in half a month. After all, there are too many disasters in the world, and people cannot always be in pain.

During the festival, offices from the court to various government offices were stopped, and Zhu Gaoxu no longer had to review memorials or hold morning courts.

So for a while, he spent a lot of time with Miao Jin, and the two of them often stayed in the Rouyi Hall. Others in the harem had some complaints about this, so Zhu Gaoxu had to say that Miao Jin was writing a book for him, so he explained it a little.

Under the huge wooden beams of Rouyi Hall, the hall room with bookshelfs on the walls still looks a little empty.

However, Zhu Gaoxu once studied here, discussed affairs with ministers, and communicated with Annan Chen family here. Now Miao Jin does a big thing with him; many memories seem to give this expensive palace a special artistic conception. After all, no matter how luxurious a house is, it is meaningless without people's memory.

It is like the big table in the middle. If it does not have the characteristics of the study room of the Han Palace in Yunnan, it will be just a sudden big object.

Miao Jin's back is still so beautiful. Her just right body lines inspired Zhu Gaoxu's various abstract imaginations, and she felt that everything around her was poetic and picturesque.

She stood on tiptoe, her whole body showed a light posture, and then got an old book on it. She looked back, smiled, and said with a little surprise: "I really found it! This is the "Mo Jing".

Miao Jin then discovered Zhu Gaoxu's eyes, her smile faded slightly, and her expression became richer. What people's language can express is indeed not as complicated as the various subtle emotions revealed during the day and night.

"It seems that you can find any book here." Miao Jin said again.

Zhu Gaoxu said: "Some of the emperors' collections are all original works of Wang Xizhi, and such rare things. If I don't choose the version, it's not too difficult to get a few books."

Miao Jin lowered her head, looked through it for a while, and said, "This book is left on the shelf, but there is no dust. Someone should have moved it recently. The emperor has read the "Mo Sutra"?"

Zhu Gaoxu smiled and said, "This is the benefit of not having to study for the sake of the imperial examination."

When Miaojin came over with the book, Zhu Gaoxu said: "The 'logic' I just mentioned has been discussed in the Mo Sutra. In addition, Greece in the 'Far West Region' (Western, the Ming Dynasty refers to Southeast Asia, India and other places west of Brunei) also had this idea; there was also the in-depth study of India.

It probably refers to a linear, causal way of thinking. This should be the simplest and simple way of thinking, so the ancestors from all over the country have such records."

"What is linear?" Miao Jin paid attention to the new statement with great interest.

Zhu Gaoxu thought for a moment and said, "It's probably like a line with direction, with a distinction between front and back. Time is linear, the past, present and future pass evenly, and mortals cannot change it."

He then said: "If we want to explain 'science' clearly, we have to trace it back to logic, otherwise we cannot explain it clearly. Because the method of "understanding the laws of all things" in science not only requires hypothetical conclusions and experiments to judge the authenticity; but also requires accurate inferences, otherwise the system cannot be expanded. The accuracy of inferences requires logic."

Miao Jin said: "I'll read this book first, I haven't read it before. Such books are rare in the world."

Zhu Gaoxu nodded. The two of them were next to the table and soon became quiet. People who are already familiar with each other are easier to get along with, perhaps because most of the time, there is no need to explain too much?

Zhu Gaoxu continued to write and draw on the paper, looking up at Miao Jin from time to time. The clear weather and open doors and windows made it very clear. On her slightly creamy face, when she buried her head, the few black hairs that fell were clearly visible, with a faint glow of sunshine.

Miao Jin also discovered Zhu Gaoxu and was looking at her from time to time. The two of them didn't say anything several times, just had eye contact.

After a long time, Miao Jin finally pointed to the paper in front of Zhu Gaoxu and couldn't help asking: "What is the emperor writing?"

Zhu Gaoxu said: "This is invented by Arabic numerals and Indians. These are letters, English-Egypt characters. Our Chinese language has richer and simpler meanings and can withstand the evolution of time; but letters also have advantages, and English is undoubtedly the simplest and easy to learn."

Of course, it is also possible to use A, B, C and D. Zhu Gaoxu is just used to using alphabetical algebra. He also accepts that all the things invented by China have been learned, so why should we exclude other people’s things?

"Why are the words invented by Indians called Arabic numerals?" Miao Jin asked casually.

Zhu Gaoxu actually likes to talk about these things with her.

But he occasionally realized the source of his happiness, perhaps just showing off his experience to beauties, not to mention that Miaojin is a "talented woman" recognized by many people, and can write books and write stories; it is the same as the gorillas who see the opposite sex and reveal their strong bodies, which are essentially the same. Perhaps humans are very primitive.

He talked enthusiastically: "The Persia or the cannibals in the Arab world have stronger military power. After conquering India, they found that the Indians were very good at math, so they captured the Indians and taught the Arabs. As a result, people in other places thought it was invented by the Arabs, so they called it.

Didn’t gunpowder be invented by our Taoist priests? It was also learned by the Arabs first. I guess some people in the distance now thought gunpowder was invented by the Arabs.”

Miao Jin accepted this statement, "People who are good at math are not necessarily good at fighting and governing the country."

Zhu Gaoxu smiled and said, "That's right. There were many conquering conquering people in India. Soon after, the outsiders there should be visitors from the Ming Dynasty?"

Miao Jin frowned, "The Lord still didn't say what he wrote."

Zhu Gaoxu suddenly said: "Triangles, three ridges, four mysterious and five, and the wonderful brocade should be known."

Miao Jin nodded.

Zhu Gaoxu said: "The calculation of triangles in the pre-Qin period was probably even more perfect after the Tang Dynasty. So I was trying to use this thing to check the calculation cannon table."

He took out a few more drawings, "This is a bastion, and the drawings have been modified countless times in the past few months. My idea is to use a concave polygon fortress to increase the firepower crossover coverage at various angles. However, this design has a very obvious weakness: if the enemy uses long-range heavy weapons, such as Huihuan, it will still pose a threat to the defenders above. The countermeasure is to use the cannons on the fortress to clear the enemy's heavy weapons at a fixed point.

With the Han King cannon that has been improved so far, the key is that the accuracy is too poor. Now, the cannon cannon can only be activated by the experience and estimates of soldiers, so it can only attack large targets, such as city walls and dense square arrays. I am trying to make a cannon watch, so that the cannon can hit far targets more accurately.”

Miao Jin said curiously: "I read the Sui and Tang dynasties before, but I thought that fighting was to win by bravery."

"The war now requires courage, but it is no longer the courage to fight, but spiritual courage." Zhu Gaoxu said.

Miao Jin nodded and said, "I have also written such paragraphs in the book "The Daily Records of the King of Han".

Seeing that she was very interested, Zhu Gaoxu continued to explain: "The way I have thought of for the time being is to have two observation points. If Miao Jin and me, we are two observation points... Let's stand separately, so we should be farther and reduce errors."

The two stood apart for a while, and Zhu Gaoxu raised his voice: "Miaojin is one of the observation points, next to me is the location of the cannon, and the desk is the target we are going to bombard. Is this a triangle?"

Miao Jin nodded in response.

Zhu Gaoxu said again: "The distance between us is fixed and can be measured in advance as a known condition. Now we use a long pole with a sight to point to the "target" desk, and the energy of the two corners is also produced. It is known that there are two angles and one side length. Using triangular calculations, the range of the shelling can be calculated immediately."

Miao Jin thought for a while, and a happy smile appeared on her face: "It's amazing to do this!"

Zhu Gaoxu also smiled and said, "This is the power of science."

He said: "There is a sight on the cannon, and the direction is very simple. The reason for the inaccurate shooting in the past is still unmatched, and the distance is still impossible to grasp. The landing point of the shell is hundreds of steps away, which is also common.

As long as the shelling distance is calculated, the range can be controlled by using the elevation angle. What is used here is kinematic verification. The orbit of the shell is a parabola, which we wrote just the day before yesterday.”

Miao Jin said innocently: "I wrote it down according to the Lord's will, but I didn't understand it very much."

Unexpectedly, at this moment, Miao Jin suddenly asked, "I don't understand even more, "Far West, England, have our fleet been there?"

Zhu Gaoxu was stunned and couldn't answer. Of course he could argue that the Ming fleet had contacted people from afar in the West. But Miao Jin was too close to him. It was easy to tell a lie, but how easy was it to explain everything?

Sure enough, Miao Jin then asked softly: "I think what we have written these days seems to make sense. But I don't understand, where does the Lord come from?"

After a while of silence in the hall, Zhu Gaoxu finally spoke, but seemed to look at it: "No one can fully understand everything around him, but it will not affect everyone's life. As long as they are not worried about what to eat next meal, or the weather is cold and there is no warm clothing, most people will not pay too much attention to other things. Only those who are particularly obsessed will obsess over the truth for the rest of their lives."

Miao Jin observed Zhu Gaoxu's face and nodded thoughtfully.

Zhu Gaoxu said again: "Can Miaojin keep it secret?"
