Zhao Yue saw the familiar and accustomed expressions on the faces of the four of them, and he was in a good mood: Well, scientific and technological personnel should be like this, but they don't know what the level is. Don't be a scumbag.

"What I'm going to teach you today is an oil press and a multi-functional duplex loom."

Seeing that the faces of the four people flashed with doubt, their eyes widened, and their spirits quickly focused, and Zhao Yue nodded his head with satisfaction.

"Before we talk about this, let's measure it first."

"Metrics?"

The four people were surprised: What is the law? Will it work? Is it easy to use?

By habit, they forgot for a moment that they were taught prodigies.

"Not bad. This measure is not accurate enough and is not convenient. What is to be done has to be very precise, so it has to be. ”

Zhao Yue didn't blame the four of them for questioning, they were used to it in their previous lives, and they only took care of pulling up a thread prepared before.

"The new unit of measurement is based on meters. Below are decimeters, centimeters, millimeters, in decimal system, there are more subtle divisions below, the current technology is not used, not to mention. ”

Li Laozhu didn't pay attention to the line, and asked boldly: "Little master, dare to ask what kind of rice this rice is?" ”

Rice? Millet? Southern rice, or northern rice? If you divide it three times on the basis of measuring something as small as a meter, how subtle must the thing to be done? I'm afraid I won't be able to do it. Of course, it's not that I can't do my skills or I am not confident, but that you are too demanding.

"Yes, if you don't understand, just ask. It's good to know. We want results. ”

Zhao Yue praised it, gave the four of them a boost, and said with a smile: "It's the rice of rice, but it's not measured by rice." The length of this line is one meter. Remember to go back and hit a meter ruler with iron. Iron has a small coefficient of cold rise. Its practical gold is the best. It's a pity that we don't have that. ”

This act is like nonsense in the eyes of the people. Weights and measures, what a big deal is this, you just pull the thread and say it casually?

Zhao Yue really has this confidence.

In his previous life, he also had a magical ability to be admired by his peers in science and technology, that is, his vision was extremely accurate, as long as it was not too strange and affected by visual judgment, he could estimate the measurement value with a glance, and the error would rarely exceed millimeters. So this thread really didn't come to him at random. Of course, he wouldn't waste time and saliva explaining to the natives about the relationship between length and the speed of light.

Seeing that the four of them nodded on their faces, but their expressions were disapproving, Zhao Yue patted his mother's leg and asked coldly, "What are you questioning?" Are you a child prodigy, or am I? ”

"Huh?"

The four of them forgot about this, and they made a loud noise, and hurriedly bowed their heads and said honestly: "Little young master forgive me." What the little master says is what he says. Let's listen to the little master. ”

. Zhao Yue scolded in his heart, too lazy to worry about the turtle, and asked coldly: "Evenly divide rice into meters, centimeters, and millimeters according to the decimal system, can this be done?" ”

What's so difficult about this, fold the line in half, and then ......, there is always a way. The four of them nodded hurriedly.

At this time, Mrs. Ning suddenly stood up and said to her son: "Dayou, now is the matter of Zhuangzi, you are the master of a village, come and sit here." I'll sit elsewhere. ”

Next to him, Zhao Xin's grandmother quickly stood up and said with a smile: "Twelfth sister, come and sit here." ”

Old Mrs. Ning smiled and was not polite.

The other old ladies then gave way in turn.

Zhao Dayou thought about it, and was just about to go over to sit, but was stared at fiercely by Mrs. Ning. Lao Zhao was stunned for a moment, then understood, turned to his wife and smiled: "That, what, it's important to get down to business." Madam, you write well, come, sit here by the table and write down everything Yue'er said. Save the four of them from forgetting after hearing it, and they have to be tired of Yue'er. ”

Zhang Yihui's face was silent, and her heart blossomed: Hmph, dare to say that my son is a demon. This is a good thing, right?

asked Mrs. Ning for a look, naturally got permission, and then sat down with a calm face, in fact, she sat down with a swaggering past, holding her son in one hand and brushing the pen in the other.

"My mother's handwriting is really good, and there is a killing aura in Juanxiu. It's really a woman who doesn't let her eyebrows go. Zhao Yue lacked literary talent, so he simply sighed, and folded the line into a triangle.

"Now that you have the metrics, let's tackle the tools. Add a vertical column to this triangle, and the two sides can be opened and closed freely, and it becomes a compass. Take one side as the center of the column, and the other side is rotated, and the circle is drawn. ”

This is simple, not to mention the four craftsmen, even other people can understand it as soon as they imagine it.

Oops, wonderful!

In the excitement of the four of them rubbing their hands, Zhao Yue talked about more than a dozen tools such as vernier calipers and protractors.

After resting for a while, Zhao Yue asked the housekeeper to move some more chairs for everyone standing to sit. There's still a long way to go. Zhao Yue didn't expect to be able to teach four turtles in a short period of time.

Beckoning to the four craftsmen, "Come and sit down." What I want to teach you below, it is difficult to explain it with a bare mouth. To draw. ”

Four people came, but they didn't take a seat.

"There is no place for us to sit in front of the Lord's house. Let's just stand and listen. ”

If you are a human being, you will go to the donkey barn. Zhao Yue was annoyed, and glared, "Standing so high, what do you want to do to suppress Young Master Ben?" ”

The four of them were startled, and hurriedly moved their chairs and sat down half-assed, far away, carefully.

Zhao Yue really didn't have the spirit to talk about them, so he continued to teach.

Zhang Yihui heard that her son wanted to draw, so she handed the pen to her son. Everyone also opened their eyes to see how the prodigy put pen to paper.

Really treat me as a fairy. I'm only three months old, and many parts of this body don't obey the call, and I have a weak heart. Zhao Yue shook his little fat hand at his mother, and looked at his mother, which means that his mother, alas, do you see that your son's little hand seems to be able to hold a pen? It's pretty much the same.

Zhang Yihui understood, her pretty face couldn't help but blush, and she quickly put away the pen quietly, saying that this is too big, and she forgot that her son is still at the level of peeing his pants, how can he use a brush.

But you don't need a pen, how do you draw?

Zhao Yue smiled, and dipped his index finger in water and simply drew a gear on the table. However, the water traces will then shrink, deform and even break. Zhao Yue failed, but he didn't blush, and took the opportunity to explain: "Do you understand? This water is tense and contractile. Well, this principle is also very useful. The boat can travel on the water, that's the principle. Yes, tension and buoyancy. Ahem, this, I'll talk about the law of buoyancy, the siphon phenomenon or something later. ”

Zhang Yihui could see it clearly, her mouth was grinning, and she almost couldn't hold back and laughed out loud: My baby son is like me......

Zhao Yue smiled at his mother, asked his mother to vacate the blank paper, and then dipped it in water to draw on the white paper.

Okay, do you see? This is called a gear, and the big gear drives the small gear...... To do this, the teeth must be small and precise, otherwise the gears will not fit each other, and they will be wasted if they can't operate normally. Therefore, from the mold must be easy to refine. This is called the reversing force shaft......

Without electric power, it can only be replaced by livestock power, and for Zhao Yue, a simple oil press has to be complicated.

Finally got the four turtles who were in a daze, and Zhao Yue was so tired that his face turned pale. The little head of the low preparation buzzed, which scared the Zhang family a lot.
