Shen Li suddenly missed the emperor. He hadn't seen him for seven years, and he was probably taller than him now.

He shook his head, getting rid of unnecessary thoughts from his mind.

All in all, after introducing some mathematical context.

Liu Dunkai put forward three major criticisms.

One is to explore the household registration system of this dynasty.

It is believed that the common people who specialize in mathematics will be classified as Yin and Yang, which will stifle the mathematics community and return mathematics to the family industry of inbreeding, which will greatly curb the development of mathematics.

Secondly, it criticizes the mathematical carrier.

Due to the limitations of the times, for thousands of years, characters have been recorded on bamboo slips. Due to the limited space, the text had to be abbreviated, which largely made the expression of mathematics less precise.

Various "Nine Chapters on Arithmetic Annotations" and "Zhou Bi Suan Suan Jing Annotations" have caused people to annotate it again and again, making a lot of repetitive efforts.

Nowadays, paper is cheap and exquisite, and the length is sufficient. Is it still necessary to save space?

Why should we stick to the simple expression of the past instead of striving for precision?

Third, there was strong opposition to the separation of mathematics and Confucianism.

What is metaphysical is called Tao, and what is practical is called tool. The Confucian component of mathematics is still too little.

After deeply understanding the epistemology proposed by the emperor, Liu Dunkai suddenly realized that any utensil has the existence of Dao - any theory should be inseparable from Confucianism.

Why has mathematics been fragmented and fragmented for a long time?

It’s because of the lack of Confucian guidance!

There is a lack of integration in research and treatment, a lack of continuity within the system, and a lack of cognitive transcendence!

To sum up, there is no Tao that rises from strange and ingenious tools to universally applicable to all things. It is not used enough in practice and the exploration of cause and effect is not done deeply.

Shen Li was quite pleased.

Today's Taoism has turned to mathematics to innovate.

After the discussion on Taoism in the second year of Wanli, Confucianism really took on a new lease of life.

I have to say that as a scholar, I feel very satisfied when I see these outsiders promoting Confucianism to such a high level.

He then looked down.

Subsequently, based on the above criticisms, Liu Kaidun put forward suggestions for those who practice mathematics - they will strive to standardize and accurately use mathematical terms; at the same time, use the guidance of Confucianism to make more efforts in practice and explore cause and effect.

Specifically, it is, first, exploring cause and effect, focusing on logical reasoning and deduction, summarizing mathematical rules, and constructing a continuous and systematic model of the original relationship of mathematical calculations.

Second, practical comparison abandons the limitations of thinking brought about by bamboo slips and introduces graphics as a supplement to logical deduction. The combination of pure rationality and practical rationality can be said to be a combination of numbers and shapes.

Below are some examples of deduction and the application of combining numbers and shapes.

It's a very good basic question. The good thing is that it makes the originally obscure question easy to understand.

Shen Li browsed every number and symbol carefully, and then...

Then breathe gradually and evenly.

Then the eyelids started to fight.

After a while, the newspaper fell from his hand to the ground.

Mr. Long Jiang fell into a deep sleep.

…

The time to fall asleep always passes quietly.

I don't know how long it took.

Shen Li felt that the carriage seemed to have stopped suddenly, and there was a commotion outside the carriage.

Affected by these, he opened his hazy eyes in confusion.

Shen Li raised his eyes and looked inside the carriage, but did not see his son.

The noise outside the carriage gradually became quieter, and Shen Li gradually woke up.

He pushed himself up, opened the car curtain, stretched his head and looked outside.

Not far away is the post station, with the words "Zhuozhou Post" written on the flickering lantern.

Of course, the carriage did not stop at Zhuolu Station.

A circle of torches stood between the carriage and the inn.

Oh... Set up a card and check, but the torch is a bit dazzling, Shen Li thought.

Hmm? Interrogation? Torch?

Shen Li was startled and suddenly woke up!

Taking a closer look, it turned out that a group of soldiers had surrounded the road ahead and were checking pedestrians!

He looked at the group of soldiers with a solemn expression. Judging from their clothing, they seemed to be the Jinyi Guards and the Beijing Camp Red Helmet Guards.

Meanwhile, my son was negotiating something with the soldiers blocking the card outside the inn.

The Red Helmets have all been sent out...

Shen Li frowned, realizing that things were not simple.

He was about to ask the servant driving the car to call him back for questioning, but he saw that his son seemed to have finished negotiating, and turned around and walked back with a solemn look.

The group of soldiers, led by Jin Yiwei, was wearing a flying fish suit and clasped his fists at Shen Li, obviously knowing his identity.

Shen Li didn't return the gift. He looked away cautiously and looked at his son.

Before Shen Yu could get closer, Shen Li could not wait.

He hurriedly asked: "What's going on? Why are there so many night checks in Shuntian Mansion? Even the Jin Yiwei and red helmet guards are sent out?"

Zhuozhou belongs to Shuntian Prefecture, only more than a hundred miles away from the capital. Important areas in the capital are never investigated without incident, let alone the Jin Yiwei and the Beijing Camp. Now with this look, something is obviously wrong!

Shen Yu's face looked a little ugly.

He subconsciously looked around before approaching Shen Li.
