A trend has recently become popular among students in the Imperial College.

That is to take Teacher Zheng Shiyuan’s math class.

The so-called mathematics is a science evolved from the mathematics technique of the Tang Dynasty in ancient times, called mathematics.

Of course, this is what Teacher Zheng Shiyuan said, and Teacher Zheng Shiyuan said that this is what His Highness the King of Liao said.

What a guy, what about the Tang Dynasty mathematics? This is a lost unique skill!

Zheng Shiyuan also has a good lecture.

He did not talk about boring and profound mathematics when he came up, but began to talk about the history of mathematics.

Students these days may not be very interested in mathematics itself.

But they are all very interested in historical events.

After all, I have to take the exam. I usually talk to others and tell others allusions but I don’t know them. Wouldn’t that be ridiculous?

Confucian scholars still need face.

So from history as the entry point, that is perfect.

Zheng Shiyuan started talking.

The legendary Tang Dynasty used mathematics to obtain official positions. "Sunzi Jing Jing" and "Five Cao Jing Jing" are the basic knowledge of introductory knowledge and it takes one year to learn it.

The primary courses are "Nine Chapters of Arithmetic" and "Island Arithmetic". The course is three years, including one-way quadratic equations, pi calculating, etc. There are also many measurement mathematics contents. During the Tang Dynasty, maps and geographic surveying in the military camps must be learned.

The intermediate courses are "Zhang Qiu Jian's Summary", "Xiahou Yang's Summary", "Zhou Feng's Summary", and "Five Classics Arithmetic". They are also a three-year academic system, involving prescription, cubic, Pythagorean theorem, and solutions to indefinite equations such as the hundreds of chicken problems.

Advanced courses, including "Qing Ancient Abbreviation" and "Embroidery".

This really involves the category of higher mathematics, and the solutions to higher order equations were perfect in the Tang Dynasty.

This stage takes seven years.

After all, it takes fourteen years to learn mathematics alone before and after graduation.

One person must enter the official school at the age of fourteen and learn mathematics. He will not be able to finish all the studies until he is nearly thirty years old before he can finish all the studies.

It is conceivable how difficult and important this mathematics is.

A very famous teacher at that time was named Wang Xiaotong, a doctor of mathematics at that time, Taishi Cheng.

In the official school, no student is afraid of him. The reason is that he has produced is really tormented.

After learning mathematics behind him, he is really prone to losing hair.

Of course, many of these things have been lost, such as "The Classic of Ancient Affiliations" and "The Story of Approaching", which did not have complete texts during the Hongwu period.

I only saw some records in historical materials.

Even the title in "Nine Chapters of Arithmetic" was previously published in the whole city, but only three people answered it!

You know, during the Tang Dynasty, this "Nine Chapters of Arithmetic" was a lesson learned by teenagers!

During the Hongwu period, no one could do it!

Some students are not convinced and may have to refute:

"Teacher, what you said is all learned by the ancients, but according to students, we should learn more about the principles of saints now. This numerology is the way of merchants and is not very important."

After he said this, Zheng Shiyuan smiled, instead of criticizing him, but said:

"Let's talk about how important it is to draw a map and determine the height of a lake. Let's talk about the saint's principles you mentioned."

Zheng Shiyuan said with his hands behind his back:

"As we all know, I am now fortunate to be the chief official of His Highness of the Liao King. It's shameful to say that although I am a chief official, His Highness of the Liao King is of extraordinary talent and I can teach very little.

Although I didn't teach much, I often talked with His Highness the King of Liao on weekdays.

I have heard of some unique insights from His Highness the Liao King.

To summarize the four words, knowledge and action are united.”

Integration of knowledge and action?

After Zheng Shiyuan finished speaking, the explanation below was in an uproar, and the students began to discuss it immediately.

"Why Zhu Xi said, shouldn't we be able to do it later?"

"Yeah yeah."

Most of the people who learned Zhu Xi's theories at this time were Zhu Xi's theories. When they heard different opinions, they were all quite surprised.

Zheng Shiyuan also knew everyone's attitude. He was also quite surprised when he heard His Highness the King of Liao casually talk about his studies on his mind.

But His Highness, the King of Liao, looked as usual and did not feel anything wrong.

Zheng Shiyuan did not know at first that this was a new Confucian theory, but Zheng Shiyuan talked a lot with the King of Liao and found the subtleties.

Moreover, the King of Liao also said that this is called study of mind.

Over the past period of time, Zheng Shiyuan has recorded the words and deeds of the Liao King while thinking about the meaning of this study of mind. Of course, most of them are like Confucius' disciples, recording Confucius' words and deeds.

These remarks by King Zhu Qi of Liao gathered together and opened a new door in front of Zheng Shiyuan.

Zhu Qi is not good at philosophy.

But Zhu Qi will chat and talk!

The study of the mind is so famous. It is a kind of profound and difficult to understand philosophical theories. When I was in history classes, the history teacher talked a lot, so he came out.

As for what it means to say, "there is action in knowledge and knowledge in action", Zhu Qi did not consider it much, after all, his thinking has long been a materialistic view.

But Zheng Shiyuan would think about it repeatedly, and now he also said the original words that His Highness the King of Liao were said in class.

Good guy, this theory was immediately furious.

The first class was spent in a great discussion on philosophy.

This is something Zheng Shiyuan didn't expect.

However, because of the emergence of the theory of mind, it was said by His Highness the King of Liao, and Zheng Shiyuan, a Confucian master, also supported it.

Among the students of the Imperial College, a huge uproar was also caused.

In the second class, there were more people coming.

Part of it is for mathematics, and part of it is for this mind.

Good guy, these Confucian scholars like to discuss such philosophical issues.

But whether it is for the reputation of King Zhu Qi of Liao or for discussion.

In recent times, the Imperial College has a strong atmosphere of discussion and learning.

They finished the discussion in class, so they naturally couldn't be idle in private.

For private gatherings, poetry gatherings, or even ordinary meals and drinks, you have to chat hard.

Starting from the Imperial College, a trend of reviving the Tang Dynasty's mathematics and exploring the spirit of His Highness the King of Liao, it was unknowingly revived.

Then, the breeze gradually gathered and was out of control.

—————

May in the ninth year of Hongwu.

Zhu Qi was sleeping soundly on the bed, and the sound of footsteps came from outside.

Zhu Qi opened his eyes in a daze and touched no one around him, he knew that Xu Miaoyun must have gotten up early again.

The footsteps outside were getting closer and closer, and then the voice of an internal official was heard:

"Your Highness, your Majesty asks you to go to court quickly."

Zhu Qi was stunned and woke up most of the time.

Go to court? What kind of court? What are I, a vassal king without a post, do you do?

Fortunately, the inner official followed and said:

"The ministers are waiting, saying that they want to discuss the truth with His Highness."

On Tao? On what Tao?
Chapter completed!
