Bright Spring

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

Under the huge wooden beams of Rouyi Hall, the hall room with bookshelves beside the wall still looks a bit empty.

However, Zhu Gaoxu once studied here, discussed matters with ministers, and communicated with the Annan Chen family here, and now Miaojin is doing a big event with him; many memories seem to endow this expensive palace with a special artistic conception.After all, no matter how luxurious a house is, it is meaningless without people's memory.

Just like the big table in the middle, if it does not have the characteristics of the study in Yunnan Hanwang Mansion, it will be just a big and abrupt object.

Miao Jin's back is still so beautiful, her just right body lines have inspired Zhu Gaoxu's various abstract imaginations, and he only feels that everything around him has a poetic and picturesque flavor.

Standing on tiptoe, her whole body showed a light posture, and then she got an old book on it.She looked back, smiled, and said with a slightly surprised expression, "I really found it! This is the "Mo Jing"."

Miao Jin immediately noticed Zhu Gaoxu's eyes, her smile faded slightly, and her expression became richer.What can be expressed by human language is indeed not as complicated as the various subtle emotions revealed in getting along day and night.

"Your Majesty, it seems that you can find any book here." Miao Jin said again.

Zhu Gaoxu said, "Some of the emperor's collections are all authentic works of Wang Xizhi and other rare objects. I don't choose editions. It's not too difficult to get a few books."

Miao Jin lowered her head, flipped through it for a while, and said, "This book has been shelved, but there is no dust. Someone should have moved it recently. Has your majesty read the "Mo Jing"?"

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

When Miao Jin came over with the book, Zhu Gaoxu said, "The 'logic' I just mentioned has already been discussed in the Mojing. In addition, the 'Far West' refers to the Southeast Asia, India, and the west of Brunei. Greece, etc.) also have ideas in this regard; there is also Indian etymology.

Probably refers to a linear, causal way of thinking.This should be the most simple and simple way of thinking, so sages everywhere have such records. "

"What is linearity?" 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 a direction, which can be divided into front and back. Time is linear. The past, present and future flow evenly, and mortals cannot change it."

He went on to say, "If we want to explain 'science' clearly, we have to go back to logic, otherwise we can't explain it clearly. Because science's method of "knowing the laws of all things" not only requires hypothetical conclusions and experimental judgments; If there are accurate inferences, otherwise the system cannot expand. The accuracy of inferences requires

It's time for logic. "

Miao Jin said, "I'll read this book first, I haven't read it before. This kind of book is rare in the world."

Zhu Gaoxu nodded.The two of them were at the table and quickly fell silent.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 Miaojin from time to time.The sunny weather and the open doors and windows make it very clear and clean.On her face, which had been lightly applied with makeup, the few black hairs that fell off when she buried her head were also clearly visible, faintly glowing with the sun's luster.

Miao Jin also found Zhu Gaoxu and was looking at her from time to time. The two of them didn't say a word for several times, just making eye contact.

After a long time, Miao Jin finally pointed to the paper in front of Zhu Gaoxu, and couldn't help asking, "What did the Holy One write?"

Zhu Gaoxu said, "These are Arabic numerals, invented by Indians. And these are letters, the characters of the English country. Our Chinese has richer and more concise meanings, and can withstand the evolution of time; but letters also have advantages, and English is undoubtedly It's the easiest language to learn."

Of course, A, B, C, D can also be used. Zhu Gaoxu is just used to algebra with letters.And he also accepts that all the things invented by Huaxia have been learned by others. Why do we reject other people's things?

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

Zhu Gaoxu actually liked talking about these things with her.

But he occasionally realizes that the source of his happiness may be just showing off his knowledge to beauties, not to mention that Miaojin is a "talented woman" recognized by many people, who can write books and talk about meeting the opposite sex with gorillas and showing | body, the same essence.Perhaps humans are inherently primitive.

He talked enthusiastically, "The Persians on the Arabian side or the big cannibals have stronger force. After they conquered India, they found that the Indians were very good at mathematics, so they arrested those Indians and taught them Arabs. As a result, people in other places thought it was invented by Arabs, so they called it.

Gunpowder was not invented by our Taoist priests?It was also learned by the Arabs. It is estimated that some people in distant places now think that gunpowder was invented by the Arabs. "

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

Zhu Gaoxu smiled and said, "Exactly. There used to be many conquerors in Tianzhu. Soon after, the outsiders over there should be visitors from Ming Dynasty?"

Miao Jin frowned, "The Holy One still didn't say what it was written."

Zhu Gaoxu suddenly said, "Triangle, hook three parts, four mysterious five, Miao Jin should know."

Miaojin nodded.

Zhu Gaoxu said, "The triangular checking calculation in the pre-Qin period, probably after the Tang Dynasty, the calculation was more perfect. So I am trying to use this thing to try to check the cannon watch."

He took out a few more drawings, "This is the bastion. The drawings have been revised countless times in the past few months. My idea is to use a concave polygonal fortress to increase the cross-fire coverage from all angles. But this design , there is a very obvious weakness. If the enemy uses long-range heavy weapons, such as return guns, to throw all kinds of flowering bombs, it will still pose a threat to the defenders above. The countermeasure is to use the artillery on the fort to attack the enemy's heavy weapons Spot clear.

With the current Hanwang Cannon that has been improved several times, the range is completely sufficient, but the key is that the accuracy is too poor.Now shooting | can only rely on the experience and estimation of the soldiers, so it can only attack very large targets, such as city walls and dense square formations.I'm trying to make a gun meter, so that the gun can hit distant targets more accurately. "

Miao Jin said curiously, "I read Sui and Tang scripts before, and thought that wars are won by bravery."

"Courage is needed in today's wars, but it is no longer bravery to fight, but spiritual courage." Zhu Gaoxu said.

Miao Jin nodded and said, "I also wrote such passages in the "Life of the King of Han"."

Zhu Gaoxu saw that she was very interested, so he continued to explain, "The method I thought of temporarily requires two observation points. If Miaojin and I, we are two observation points... Let's stand separately, farther away to reduce errors."

The two stood at a distance, Zhu Gaoxu raised his voice, "Miaojin is one of the observation points, the cannon is next to me, and the desk is the target we want to bombard. Is this a triangle?"

Miao Jin nodded in response.

Zhu Gaoxu continued, "The distance between the two of us is fixed and can be measured in advance as a known condition. Now we use a long rod with a sight to point at the "target" desk, and the size of the two corners can also be measured. Yes. Knowing that there are two angles and one side length, using trigonometry, you can immediately calculate the range of the bombardment.”

Miao Jin pondered for a while, with a delighted smile on her face, "You can still do this, it's amazing!"

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

He said, "There is a sight on the artillery, and the direction is very simple to observe at three points and one line. The reason for the inaccuracy in the past is that the distance cannot be grasped. It is common for the shell to fall hundreds of steps away.

As long as the shelling distance is calculated, the range can be controlled by the elevation angle.What is used here is the checking calculation of kinematics. The trajectory of the shell is a parabola, which we just wrote the day before yesterday. "

Miao Jin said innocently, "I wrote it down according to the meaning of the Holy Majesty, but I didn't quite understand it."

Unexpectedly, at this moment, Miao Jin suddenly asked, "The concubine doesn't even understand, 'Far West', the country of England, have I ever been to the fleet?"

Zhu Gaoxu paused for a while, unable to answer.Of course he can quibble, the Deming Fleet has contacted people from far away in the West.But Miaojin is too close, it is easy to tell a lie, how easy is it to explain everything?

Sure enough, Miao Jin then asked softly, "I think the things we wrote these days seem quite reasonable. But I don't understand, where did the Holy One get it from?"

After a while of silence in the hall, Zhu Gaoxu finally opened his mouth, but he seemed to be looking left and said, "Everyone can't fully understand everything around them, but it won't affect everyone's life. As long as you don't worry about what to eat next, or When the weather is cold but there are no warm clothes, most people will not pay too much attention to other things. Only those who are particularly persistent will be obsessed with the truth all their lives."

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

Zhu Gaoxu asked again, "Can Miao Jin keep it secret?"

She smiled immediately.

Chapter 755 It's a wonderful affair

In the morning mist, there is still a vague smell of pollution after fireworks.

The messy items that can be seen from time to time in the imperial city and have not been cleaned up are all remnants of the decorations and celebrations of the palace on the Lantern Festival.These things are usually invisible, after all, there are many people in the palace who keep it clean.
