314.

After the elders' meeting, Cheng Li started the afternoon lecture without resting.

According to the course arrangement, the afternoon class will not be "Deconstruction of Spells".

The Deconstruction of Spells class is scheduled to take place every morning, while the afternoon class is dedicated to the principles of science.

In order to allow most cultivators to better cut into scientific thinking, Cheng Li chose spells, which are more familiar to cultivators, in the morning class.

In the afternoon class, Cheng Li chose arithmetic, which is a relatively familiar entry point for cultivators on Qingling Island.

It can be said that arithmetic, that is, mathematics, is the same discipline shared by the cultivation system of Qingling Island and the scientific system on the earth.

Therefore, there is no doubt that in order to make the people of Qingling Island accept scientific thinking, it is best to start with arithmetic.

The original arithmetic system on Qingling Island, thousands of years ago, was not much inferior to earth mathematics, which can be seen from the fact that the first generation of ancestors of foreign Daoists can pass the test of the 3000th layer of the arithmetic tablet.

However, limited by the metaphysical thinking of the Xiuzhen system, the arithmetic inheritance of Qingling Island still adopts the inheritance of the Xiuzhen method, rather than an open education system, so that the arithmetic knowledge is limited to a few elites.

In addition, the arithmetic system on Qingling Island is also influenced by metaphysical thinking, and does not express the operators and formulas as formally and precisely as earth mathematics, but is more inclined to metaphysical perceptual expression, which makes the arithmetic inheritance and learning difficulty of Qingling Island more difficult to learn than the mathematics on earth.

Therefore, arithmetic on Qingling Island has always been a very difficult and difficult subject to understand, and only a few elites can learn it.

Because of this, the arithmetic system and inheritance of Qingling Island are very fragile.

Therefore, in the Great War thousands of years ago, the arithmetic system of Qingling Island was cut off after the Great War, and the knowledge left behind was not one in ten.

So much so that the current arithmetic level on Qingling Island is not too high.

Based on some of the original shortcomings of Qingling Island's arithmetic, Cheng Li unceremoniously copied the modern mathematical system on the earth.

However, the process still retains the core and essence of the "Yin and Yang Thought" in the original Yin-Yang arithmetic inheritance, so that it can be integrated with the modern mathematical system of the earth to a certain extent.

In this way, it is to make it easier for this group of students on Qingling Island to accept earth mathematics.

Second, Cheng Li believes that in the original arithmetic system of Qingling Island, the core of the yin and yang thought does contain the charm of mathematical truth.

Cheng Li believes that the mathematical system on the earth and the inheritance of yin-yang arithmetic on Qingling Island can be regarded as having their own merits.

The mathematical system on the earth has the advantages of being more rational, objective and accurate, but the disadvantage is that it is too mechanical and rigid.

The inheritance of yin-yang arithmetic on Qingling Island is more sensual, with the mellow and accessible characteristics of metaphysics, and it has the charm of connecting one law to ten thousand laws. But the disadvantage is also too specious, not accurate and objective enough.

It can be said that the mathematical system on the earth is more rational, while the yin-yang arithmetic inheritance of Qingling Island is more emotional.

Therefore, Cheng Li finally decided to integrate the two to a certain extent.

Under the premise that most of the whole system architecture adopts the modern mathematical system of the earth, the core ideas are integrated with the yin-yang arithmetic of Qingling Island to a certain extent, so that some perceptual mathematical ideas can be integrated into the rational, accurate and objective basis of the earth's mathematics.

This is Cheng Li's idea, or it can be said to be Cheng Li's ambition, he not only created a new field of integration of science and cultivation in the cultivation system, but also integrated arithmetic and mathematics in mathematics.

The difficulty of such a fusion is naturally very high.

Therefore, Cheng Li just took the opportunity to give lectures to these students as his own thoughts, and carried out self-speculation in the course of lectures, which also gave Cheng Li the opportunity to truly integrate arithmetic and mathematics perfectly, and create a new road of mathematics.

"Okay, now for our second lesson of the day, in this lesson we will not talk about spell deconstruction, but arithmetic...... Or rather, it's not arithmetic anymore. ”

Cheng Li said first to the 109 Jindan period bigwigs below.

"In my hometown, arithmetic is called mathematics. ”

"The mathematics in my hometown has many similarities with the arithmetic in Qingling Island, but there are also many differences.

"At the beginning, when I first came to Qingling Island, I found that the level of arithmetic on Qingling Island was not very high, probably only about one-tenth of the mathematics level in my hometown. ”

"But later, after I obtained the Yin-Yang arithmetic inheritance of Qingling Island in the arithmetic tablet, I found out that Qingling Island's current arithmetic level is low, just because the inheritance has been broken.

"The level of yin-yang arithmetic in Qingling Island thousands of years ago was quite high, and it was basically the same as the level of mathematics in my hometown. ”

"I should be the only person who is proficient in mathematics and arithmetic systems now, so I should be more vocal about these two systems. ”

"After in-depth research and comparison, I found that the mathematics in my hometown and the arithmetic in Qingling Island have their own advantages and disadvantages, so in the end I decided to integrate the two to a certain extent to form a new discipline, which is the next lesson we are going to take......"

"The name of this new discipline, I think it's called, arithmetic!"

Cheng Li's opening speech quickly aroused the curiosity of these Jindan period bigwigs.

If it were just to explain to them the inheritance of yin-yang arithmetic thousands of years ago, I am afraid they would not have such great interest.

After all, human beings can arouse their curiosity more when it comes to completely unknown territories.

So, next, these Jindan period bigwigs listened to Cheng Li's eloquent talk for two hours, and Cheng Li explained some of the essence of the Yin-Yang arithmetic inheritance in simple terms, refining it with modern mathematical thinking and symbols, so that these Jindan period bigwigs listened to it with relish, as if they had opened up a new world.

The content explained by Cheng Li progressed quickly, and he almost finished the content of junior high school mathematics in one class.

On the one hand, this is due to the cultivators' super thinking ability and comprehension ability, and on the other hand, it is also due to the fact that most of the students present have a certain foundation in arithmetic.

In the morning, Cheng Li used the arithmetic test when he took the entrance examination, and a very important purpose was to grasp the original arithmetic level of all the students present.

Then Cheng Li found that eighty percent of the 109 students already had arithmetic knowledge equivalent to the earth junior high school level and part of the high school level.

Cheng Li is now just retelling the original arithmetic knowledge of Qingling Island in a scientific way, so it will naturally be fast.
