Chapter 57 Mathematics

3days ago traverse Novels 3
The emperor neither attends court nor reads memorials, and he never sees anyone all day long.

However, people still know where he is doing: there are so many people in Penglai Palace, and they still have to take turns to serve the food and daily life in the bedroom of Jincheng.

Xue Chongxun did not do the emperor's job and temporarily changed careers and started doing what Shuli said.

First of all, you write about mathematics, which is the basis of all science subjects.

He started writing about Arabic numerals, which were invented by Indians and were founded very early.

Xue Chongxun felt sorry. Master Xuanzang ran far away to India to retrieve Buddhist scriptures, why didn’t he bring back Arabic numerals?

This thing is very simple, but it is more suitable for math than Chinese characters, and is mainly convenient for formula operation.

After the Buddhist scriptures were brought back to the Tang Dynasty, they were not localized. Many people went to temples to pray to gods and worship Buddhas, which was very utilitarian. In Xue Chongxun's opinion, those scriptures really did not play much practical role. Instead, Arabic numerals were very valuable.

However, the Central Plains only attaches importance to the ways of sages and does not attach much importance to such things.

Explain the rules of Arabic numerals, including decimal points and four operating symbols, are very simple, and Xue Chongxun finished writing them within an hour.

This kind of thing comes with text comments, so literati can understand it at first glance, so there is no need to worry at all.

Isn’t it a pediatric technique for those who can read the Four Books and Five Classics to understand these things?

The ancients were obviously not as stupid as they thought.

Next is arithmetic, and he doesn’t have to write too much. He used to know how to add, subtract, multiplication and division algorithms now, otherwise how did he get the abacus?

Xue Chongxun only needs to give examples of various algorithms using Arabic numerical formulas.

By lunch, he had already finished writing such a large part. This is something for bureaucrats and literati. It can be described briefly without long and complicated descriptions.

If you want to use this kind of thing to teach children in the future, it will be the official's business, and Xue Chongxun doesn't have to do it himself.

He ate something in a hurry and began to concentrate on writing. Anyway, there were other things that the palace maids were serving him, so he didn't have to do anything else.

In the afternoon, he began to write algebra and plane geometry, and at the same time, and if he was tired of writing, he would change his name.

In terms of algebra, because of habits and convenience, letters are still used. After all, it is a bit strange that A, B, C and D are sandwiched in Arabic numerals. For example, a is pronunciated, and b is just a symbol. It will be accessible when others see the habits.

Geometric convenience is more troublesome, involving the issue of weights and measures. Although Qin Shihuang also re-stated that the same text and the same tracks of the car, Xue Chongxun decided not to introduce units such as rice and decimal rice after considering it. Anyway, the meter, size and size are ready-made, and the world has also become a consensus on using habits. Just use it, and the left and right are a unit of measurement.

It is not certain that China will develop in this area in the future, and others will think that the size unit is more formal when studying...

This thing is not a military secret. Xue Chongxun can issue laws to strictly prohibit the leakage of gunpowder cannon manufacturing technology, but other tribes cannot keep it confidential if they want to learn this.

Equations, systems of equations, plane geometry proof equilaterals and equiangular angles are all simple things. Xue Chongxun spent all the time and slept and finished it all on the third day.

It's just a few formulas and argumentation processes, a small game for junior high school students.

On the third day, Xue Chongxun had a headache when he started to involve vectors, sets, and functions, and then parsing geometry and stereo geometry.

I remember that I scored more than 130 points in the college entrance examination in my previous life and had more than 280 points in the comprehensive science exam. But after so long, what I did at this moment was not just about doing questions, but mainly to describe the inferences of each formula clearly and convince others.

This is a bit painful and a very laborious thing.

He also thought that more inferences in advanced mathematics were more troublesome, so he planned to only produce calculus, and this relatively high-end content would not be included in the imperial examination.

After all, advanced mathematics is applied to modern technology. In this environment, there is no actual value, but can only be regarded as a Go-like intellectual game.

Princess Jincheng's palace was soon filled with various manuscript papers, and was thrown everywhere by Xue Chongxun.

He was used to the life of having a meal and opening his mouth and reaching out his hands. He was used to throwing it away after writing a page, thinking that someone was waiting to clean up, but he didn't know who dared to touch the palace maids?

Most of them didn't even know a big word. The calculation formula on the ground in front of them seemed to be like a book of heaven. If the emperor couldn't find what he put, he might not have to use his golden words and jade words, Princess Jincheng would have to pull out their skin.

The palace maid who delivered the meal carefully whispered when she left the palace. A palace maid said: What is the emperor writing, it has been a long time since she was writing.

Another said: Maybe we are calculating the fate of the country, so let’s not talk too much.

Xue Chongxun inside has been chanting several times. It would be great if you have a pencil, but everyone doesn’t know what a pencil is, so naturally there is no place for him to get it.

Princess Jincheng asked Yu Liben, and Yu Liben was unheard of.

She understood the things written by Xue Chongxun from the beginning of Arabic numerals. The more complicated formulas involved more formulas. She could not remember all formulas in a short time, so the reasoning process was chaotic.

But she knew what Xue Chongxun was writing about, as he said about mathematics.

He hasn't changed his clothes and took a shower for nearly ten days. His image is almost unkempt. Others want to serve him in a bath and change clothes, but he wants to be angry.

One day, I was feeling irritable. A palace maid accidentally messed with him. He directly ordered him to beat him and beat him half to death.

Apart from eating, drinking, defecating, urinating, and sleeping, he spent the whole day fiddling with the thing.

The Eunuchs also made various strange tools as required.

Jincheng was also quite depressed. Although Xue Chongxun stayed here all day, he did not look at her in a chat from time to time, and now he completely thought she was a wooden man, and he didn't go to the bath to peek at her taking a bath.

The palace was full of paper, and even the walls were covered with various figures.

Moreover, I don’t know how long this kind of life will last, and I can’t tell that Xue Chongxun has the intention to stop writing.

The eunuch Yang Sixu came to report that Du Xian continued to provoke a war in Yingzhou, led his troops from the county magistrate to capture the eastward attack on Gewuzhou, and robbed and massacred tens of thousands of Hu people of all races. The court officials were very dissatisfied and believed that it was not conducive to stabilizing the border, so they wrote a large number of memorials to replace Du Xian.

As a result, Xue Chongxun said: I haven’t defeated the battle yet, why are you nervous?Isn’t Gewuzhou the territory of the former Tang Andong Protectorate? There is nothing wrong with taking it back. How could Dongyi have so many things to surrender quickly?Du Xian led his troops for a day or two, not a person who was ignorant of his importance, he had his own sense of responsibility.

Yang Sixu hurriedly advised: When Du Xian was in the Western Regions, he had only 4,000 subordinates, so he dared to march straight into Xiaobolu to fight the Tubo army.Now that I have more than 100,000 soldiers and horses in my hand, I am afraid that I will be too eager to open up the territory and have no long-term considerations.

Don't care.Xue Chongxun said, "Don't the Political Affairs Hall want Cheng Qianli to build the city?"After I think about this, it will be no longer too late to replace Du Xian.
