Poor family mother and son

Chapter 577 Teaching
Falling in love at first sight is often a matter of love at first sight. Xiao Bao felt that the two girls had bad eyesight, and fell in love with them without distinguishing between male and female.

If you want to say that you look good, then you have to be, right?He is tall and strong and has a good personality.

As the saying goes, the way of heaven is like reincarnation, whoever is bypassed by the sky.

Don't think that Chu Yuan, who was not criticized, escaped the catastrophe.

With ears as sharp as his, how could he fail to hear the words of the three and a half older children next door?He is suffering the most in his heart now.

My daughter-in-law hasn't caught up yet, and it turns out that the man is also thinking about it, and the woman is also thinking about it.

As far as Chu Yuan's appearance is not bad, Chu Qing thinks he looks good, he looks thin in clothes and fleshy in clothes, and usually boys work shirtless, Chu Yuan's figure is the most similar to Bruce Lee.

People also want to be as tall as they are tall, and as long as their legs are. When they don't scold Chu Qing, their face looks pretty good.

Chu Qing always fantasizes that if she can wear it back, she must let her son exercise well and grow into a good figure like Chu Yuan.

As soon as the three of them started talking, Chu Qing and the others came back.

Gan Lai stepped into the room immediately, it was refreshing, and he continued to eat after sitting down, not feeling cold.

Those young masters were beaten for nothing, because Huo Mingfu had to keep a low profile before the exam, so he had to bear it for the time being.

But let the young masters of the four major families be cautious, they have to inquire, what is the origin of that surnamed Liang?
Not to mention that they want to inquire, the magistrate of Yubo County also wants to inquire.

Although he knew that this son was not good enough, he always wanted to take shortcuts to curry favor with the son of a high-ranking official in order to show that he was useful to the family, but he did not repent after repeated setbacks.

Is now the time to mingle?Even the magistrate has changed, and the officialdom is tense, how can we act rashly!

But my own son can beat and scold, but others can't!

In the days that followed, the county magistrate sent people to collect information about Chu Qing and his party, but unfortunately, apart from the two experiences of his son's quarrel with Chu Qing, there was nothing else.

On Chu Qing's side, after hearing Zhuo Yao's recitation of Geng Qianhu's "warning", he also belatedly realized that he had inadvertently picked up a girl, and was a little embarrassing.

Don't blame her for being dull, if you don't think in that direction, you won't see the signs of it, besides, you are a woman!
Chu Qing decided that the vacation would be long anyway, so he would stay in the academy for a few days and relax.

But when people are free, they have to find something to do. As the saying goes: Beating a child on a rainy day is also idle. Chu Qing "checked" Xiaobao's homework.

This is actually the real purpose of this trip.

Chu Qing didn't mind Xiaobao's participation in the imperial examination, unless he could protect his official status and life, otherwise, even if Xiaobao was admitted to Jinshi, how dare he let him become an official?He would be crushed to death in minutes.

Therefore, life-saving is the first priority.

"Little Treasure, starting today, I'm going to teach you some manual lessons." Chu Qing started like this.

"Mother, are you going to teach me how to make a grenade?" Xiaobao's eyes brightened.

Chu Qing: "Yes, I'll teach you how to do it. I brought some ready-made gunpowder with me when I came here this time, but I have to teach you how to make it first."

Xiaobao: "Yes, yes, yes! Teach a man how to fish!"

Chu Qing: "It's not enough just to know how to make it, you also need to know why it's made like this, and you have to figure out the reason behind it."

In fact, knowledge is a thing, if it is easy to teach, it is easy, and it is troublesome if it is said.

It's simple because, if you have a certain amount of hands-on ability, you can achieve good results even if the principle is not very clear.

For example, in the matter of gunpowder, the ancestors could not write reaction equations, but they could still make firecrackers and fireworks.

So where is the power of knowledge?It is to exert the greatest power of gunpowder.

So this matter is a trouble for Chu Qing.

Because Xiaobao has many questions: "Why do you have to boil it like this? Can't you leave the stove grate?"

"And what is sodium nitrate?"

"What does oxidation mean?"

"What do you mean by crystallization and dissolution?"

"Then why is it mononitrate, disulfide and three charcoals?"

"Why do you add sugar and what effect does it have?"

Answering a question leads to a series of questions.

Knowledge is systematic. If you talk about a certain part from the beginning to the end, you really don't understand it.

But did ancient people really not be able to learn mathematics, physics and chemistry?otherwise.

After Chu Qing taught Xiaobao how to make black powder, he began to teach Xiaobao about geometry and math calculations along the way.

The basic four arithmetic operations are not too difficult for Xiaobao. He has already learned them in school, but they don't use them very much. They can just be practiced through geometric knowledge.

Let's talk about geometry first, the reason is very simple, it is "rules".

"Is "Historical Records Xia Benji" readable?" Chu Qing said, "It is said that Dayu' left the standard, right the rule'..."

The interface on the little BMW: "At four o'clock, to open Kyushu, pass through nine roads, improve Jiuze, and travel to Nine Mountains."

Chu Qing nodded: "Da Yu always carries the level and the ink to measure the straightness, and the compasses and squares to delineate the diagram. What are the functions of these tools? It is measurement;
What about after the measurement?Calculate; what is the use of calculating?
Don’t you have the "Zhou Bi Suan Jing" in your school textbooks, in which Shang Gao said, "Using a flat moment to straighten the rope, straighten the moment to look at the height, cover the moment to measure the depth, and lie down to know the distance", look, measure the earth... ..."

Xiaobao's most troublesome "Zhoubi Suanjing" was explained by his mother, and he felt that it was much easier to understand. By the way, he also learned the Pythagorean theorem.

The Pythagorean measurement technique summed up by Shanggao was proved by Pythagoras more than 600 years later. As a result, he obtained the naming right, which was a pain in Chuqing's middle school.

The greatest benefit that time travel brought to Chu Qing is that the knowledge he has learned has found a foundation in this time and space.

In Chuqing's time and space, she often heard young colleagues discussing the country's unsystematic mathematics. At that time, she felt that what they said was wrong, but she didn't know how to refute it.

Now she can somewhat refute it. Huaguo does not have mathematics without a system. If it is not systematic, how can it continue?
It's just that these young people don't have systematic historical knowledge.

It's not that Huaguo doesn't have systematic mathematical knowledge, it's just that it hasn't been properly promoted and developed because the ruling class doesn't pay attention to it.

The development may be slow, but it never stops, let alone absent.

I really hope that young people can calm down, sit in the library, and read the records of their ancestors carefully. Only by understanding history can they grasp the present and the future.

For several days in a row, Chu Qing taught Xiaobao mathematics and physics during the day, and chemistry after dinner, and taught anything she could combine with reality.

Xiaobao entered the "state of college entrance examination" early.

Intensive study has caused Xiaobao to consume a lot of energy. Before that, Chu Qing took care of "three meals and two o'clock" like when he was a child, which is far from enough. Now it is six meals a day.

From time to time, Gan Lai would come to attend classes in order to mix with Xiao Bao about the food that Chu Qing made by himself. Chu Qing was surprised to find that although Gan Lai had no foundation, she was a fast learner.

In order to facilitate calculation, Chu Qing taught Xiaobao the Arabic numerals. For Gan Lai, who doesn't like to write and struggles to learn, Arabic numerals are her salvation.

Therefore, in terms of calculation, Gan Lai has made great progress.

As for the mastery of knowledge, the two children are surprisingly similar...unbelievably complicated.

Just like...
