Royal Road - Chapter 89

[Chapter 89]

Crowded among the refugees, Liu Jian was surprised to find that Taixingxing was a little different from what he thought.

Seeing that the servants of Liang’s residence had a few conversations with the defending soldiers, the gate opened.

Not only the people around him, but even the refugees behind them also went to Xingdao, and no one has seen any money to pass the customs, so let them enter Bingzhou like this?

This is the main road from Sizhou to Bingzhou, passing through Taihangxing and detouring to other places to save more than ten days of travel.

Logically speaking, let alone the refugees, it is not easy for the people of the Liang residence to pass the border. How could they solve the problem in one sentence?

Li Xin was naturally elated to be able to enter the border so easily, but Liu Jian was not as big-hearted as he was, so he endured and endured, and finally couldn’t help but ask, “A’an, why is it so easy to pass the border now?”

Liang An smiled: “Go through the border. It’s not easy, but we are from the Liang residence, how could anyone stop us?” The

Liang residence’s face has already worked so well?

Liu Jian looked at the group of refugees behind him: “What about these people? Could it be because of the Liang Mansion?”

“I can’t tell. It is said that Gaoducheng is recruiting refugees? Well, I only go out for two or three months. Now, I really don’t know what the mansion has become now.” There was regret in Liang An’s tone.

What can it look like in two or three months?

Liu Jian was confused and didn’t ask many questions, so he had to follow behind the crowd and walk along the rugged path.

After walking for a day and staying in Taihang Pass for another night, I came to Bingzhou.

The one that arrived first was naturally Gaoducheng.

Because of the large number of displaced people, many shacks were built outside the city, but there was no sense of clutter.

A few yamen guards stood outside the city, and when they saw the refugees, they immediately took them to the shack.

In the distance, more than a dozen cows and countless men and women are cultivating the fields, and it is not known whether it is to open up wasteland or catch the spring. It is a busy scene.

Seeing the busy crowd in front of him, Liu Jian immediately calmed down a bit.

Such a scene of spring ploughing, even Qingzhou may not have seen it for many years.

It seems that Gaodu has a very diligent county magistrate, and the Liang Mansion is near Gaodu, which should also benefit a lot. It seems that A’an’s words are true.

However, when the gate of Liangfu Village really appeared in front of him, it still surprised Liu Jian: “In this village, are all under the jurisdiction of Liangfu?”

This is quite a large piece of land, and it is surrounded by Liangfu. Woke up?

Liang An’s eyes lit up, and he said excitedly, “This gate was not built when I left. But in winter, there is such a strong fortress, so why should Liu Langjun worry!”

This is within two months. The built gate?

Looking at the huge gate tower about 30 feet high in front of him, Liu Jian couldn’t believe it.

But telling such a lie is meaningless. Could it be that Liang Mansion really has such strength?

Believing in doubt, he drove his horse into the village.

The scene inside is the same as that outside Gaodu City, and it is even busier. There are farmers working on both sides of the road, the fields are still overturned, and the rushing river water pours into the fields along the ditches.

If he hadn’t known that there was a severe drought in the state in the past two years, he would have thought that the weather here was good and it was a paradise on earth!

It seems that the Liang Mansion is indeed a good place, just look at what Liang Langjun asked them to do.

In such a prosperous manor, even accompanying the owner to study the horoscope is a good job!

Of course, Li Xin didn’t think so.

“You are the master of Liang’s residence? Can you help me print the manuscripts left by Master?” Unlike the others, Li Xin didn’t show any surprise when she saw Liang Feng, and got straight to the point.

Liu Jian was taken aback: “Zile, this is the Marquis of Liang, you mustn’t be rude!”

Looking at the two young men in front of him, Liang Feng smiled and said, “Of course, as long as Mr. Liu proofreads the “Nine” Zhang Suanjing can be printed in the Liang House. Just like the new Treatise on Febrile Diseases, more than 200 volumes have been published, and in a few days, the world will know it.

” Li Xin, “New Treatise on Febrile Diseases” But having seen it, it was this excellent book that made him decide to leave Qingzhou and come here.

Unexpectedly, this book has now printed more than 200 copies!

Wouldn’t that have all the literate homes in Bingzhou?

If the “Nine Chapter Suanjing” annotated by his master could be published, wouldn’t it also be famous all over the world?

!

Thinking of this, Li Xin immediately turned his head to Liu Jian and said, “Senior brother, this is a good place! Let’s go after we finish printing the book!”

Liu Jian said, “…”

Thousands of warnings and ten thousand orders, in the end, they still act so recklessly!

Liu Jian was almost embarrassed to look at the smiling face of the person in the main seat, and said embarrassedly: “I don’t know why Lianghou invited us here?

” The mountains are high and the rivers are deep. It just so happens that my house is preparing to draw a map, and I want to borrow two talented people…” Before

Liang Feng finished speaking, Li Xin shook his head: “Measuring the mountains is time-consuming and labor-intensive, and it doesn’t make much sense. , I don’t want to do it.”

Liang Feng choked: “Then ask two professors and apprentices, let them survey the painting?”

“There are too many stupid people, who will be patient to teach?” Li Xin snorted disdainfully, “I still If you have to sort out the manuscripts left by Master, and continue to study and calculate, how can you have such spare time!”

This is too lack of common sense to communicate, and it would be strange if someone else didn’t kick him out.

No wonder he betrayed his original teacher, went to Qingzhou to apprentice, and wrote dozens of volumes of manuscripts from the teacher’s house, and came here to ask for printing.

For this kind of research-oriented talents who are obsessed with mathematics, I am afraid it is not easy to lure them with interests.

After thinking for a moment, Liang Feng suddenly said: “Actually, I always have one thing in mind. Is the land under our feet flat?”

Hearing this, Li Xin sneered: “Of course not. It is said, ‘The sky is like a chicken, the celestial body is as round as a projectile, the ground is like a yellow in a chicken, and one lives alone.'”

This is the record in Zhang Heng’s “Annotation of Armillary Heaven”.

Not quite the same as the previous Gaitian statement, Zhang Heng believed that the sky is a sphere, and the earth is a half ellipsoid, with water below it connecting with the sky. Only in this way can the astrology and mathematical principles be explained.

As a great mathematician, Liu Hui wrote the chapter “Heavy Differences”, and he lived in Shandong all the year round. Naturally, he has seen the scenery of mountains and islands in the sea, and it is not difficult to draw a conclusion similar to Zhang Heng.

However, Liu Hui’s interest is in pure mathematics, and he does not have deep research on astronomy. Li Xin only knows about it and doesn’t pay much attention to it.

Unexpectedly, Li Xin knew about the curvature of the earth’s surface. The semicircle theory is estimated to be the limit of human imagination of the earth before the discovery of gravity.

Liang Feng said happily: “That’s true! I think the east-west direction is roughly the same, but the north-south direction is very different. Only the surface of the earth is spherical to explain the difference in the weather between the north and the south. Since it is a spherical surface, it should be able to calculate the size of the ball. Yes. I don’t know that Mr. Liu has been studying all his life, maybe he can calculate the area of the semicircle under his feet?”

“Huh?” Li Xin blinked.

There is also a description of the length of the earth in the “Zhou Lu Suan Jing”, but if the surface of the earth is not flat, how can the numbers be correct?

The number of circumscribed circles and the difference of weights are Master’s proud learnings. Using these two, it seems that the surface area of the earth can be re-measured.

Seeing Li Xin’s move, Liang Feng chased after the victory: “If you want to measure the geodesy, it’s not a day’s work. It’s better to stay in the mansion, edit Mr. Liu Lao’s manuscripts, and teach some assistants. When the situation is peaceful, take the assistants to cross. Famous mountains and rivers, measure the surface of the earth, and draw a map that is in line with the study of serious differences, isn’t it the best of both worlds?”

Seeing the man in front of him say a few words, Li Xin’s heart was tingling, and Liu Jian hurriedly stopped in front: “What Lianghou said was refreshing, However, there are still many doubts that have not been resolved. If you spend your whole life on the map of the world, I am afraid you will miss your learning.”

If you really let Zi Le run to draw the map, it is estimated that he will be involved in this life. .

This person in front of him is not like those noble people who like to count, and he can’t use a clear talk to pass them off.

How do you pass on what your grandfather left behind?

Liang Feng was not annoyed when he was stopped, and asked with a smile, “I don’t know what technique Liu Lang is good at?”

Liu Jian is not as versatile as Li Xin, and simply said: “I prefer cutting a circle.”

“Well .

The weight difference can measure mountains and islands, what can you do with a circle?” Liang Feng asked curiously.

Liu Jian was at a loss for words.

Circumcision is the work of my grandfather’s whole life, but how should I explain it to others?

In the “Nine Chapters of Arithmetic”, each chapter is a practical solution to the problem, even the difference is no exception.

Seeing that Liu Jian couldn’t answer for a while, Liang Feng said: “Since it is round, there should be a lot of bypasses. Just like the waterwheel recently developed by Liang’s house, it is a perfect round, but it is too large to build. It’s too difficult. If Liu Lang could make it a bit more concise and improve the effect, it would be great! Also, the projectile path of the bow|crossbow is also an arc. Is shooting more accurate?”

Hearing Liang Feng say this, Liu Jian’s eyes lit up: “Maybe you can give it a try!”

Applying what you have learned is the weakness of any researcher, and Liu Jian is no exception.

In fact, he was not very interested in the advanced arithmetic that his grandfather studied, but was very addicted to the art of cutting a circle.

If we can use cutting circles in our daily life, can we make this method spread more widely?

Looking at his shining eyes, Liang Feng couldn’t help but breathe a sigh of relief.

The impact of mathematics, especially geometry, on science and engineering can be enormous.

Nowadays, there are many skilled craftsmen in various workshops, but what they know is only “skill”, which is a vague concept based on experience.

If there is “magic” as a guide, it is possible to pierce that window paper and solve some problems that cannot be solved only by experience.

This is the true meaning of “Math is the mother of science”.

After finally abducting two genuine disciples under the name of Liu Hui, how could they be wasted on drawing and charting?

Putting on a warm smile, Liang Feng said, “That’s very good. In the future, you can continue to study in the mansion, and the Liang mansion will be responsible for the basics If there are any problems that cannot be solved, I will show them to you.”

Seeing that the senior brother seemed to agree, Li Xin immediately said: “I also cut two bamboo slips, and it will take a lot of slips to count!

” Paper, you can use paper to record daily calculations. I will also order someone to make a blackboard for you to replace the sand table.” Liang Feng replied in a big package.

“Senior brother, you can use paper here!” Li Xin was immediately excited. She covered food and shelter, used paper as she pleased, and even printed books. Is there a better place than this?

Liu Jian hesitated for a moment: “Do you have a monthly salary?”

Of course, food and lodging is good, but how can you guarantee it if you don’t have money left?

Even if you are cheeky, you have to ask clearly about it.

“According to the standard in the government, three rice grains per month. If you teach a disciple, add two more silks; if you help the workshop to develop a usable tool, you can also get a reward. I don’t know how good it is?” Liang Feng asked rhetorically. .

Looking at the smiling face of the man in front of him, Liu Jian swallowed his saliva: “So good…”
