Chapter 173 The little brother who made a mistake

I found a piece of bamboo, but it's a little difficult to hold a pen with my own hand now. It's still not easy to sort out a very accurate scale on this.I can only trouble my little brother.

Duanmuwei said what she thought of the ruler.There are no such terms as meters, centimeters, and millimeters here, only such terms as zhang, chi, and inches.Then, you have to write down the conversion formula yourself.Then convert it.Then explain it to the younger brother.

Qinglian, who was listening with her, fell asleep after listening to it.In the end, he lay down on the table and whispered.Bei Mingyan helped her put on a coat instead.Then listen carefully to what the little junior sister told me.

This knowledge is something I didn't know before.For a studious prince, this is new knowledge, so he must work hard to learn it well.

And the more I listen to it, the more I feel that my junior sister is so amazing!Can think of such a precise thing.I was also afraid that I would make a mistake the first time, so I seriously went to find another piece of wood that was a little worse.Do it yourself first.

Duanmuwei couldn't do anything by herself, so she could only use her mouth. Seeing that some of the little brother's operations were not right, she pointed it out again.Instead, the two discussed it, and after a while, they really drew the prototype of a ruler.

Although it is a small thing, it is also a big reform here.Because what they use to measure the length is rope or hand tie!

Looking at the things he made, Bei Mingyan was also very excited. He didn't expect a new thing to be born in his own hands.

In order to try what I did, I wanted to draw a square picture of five centimeters on this scale.

However, before Duanmuwei had time to say it, Bei Mingyan destroyed the scale he had drawn with his own hands.

Because he used a brush to draw.With such a heavy stroke, the ink is directly drawn on the ruler, and the imprint on the edge of the ruler is covered by ink.I can't get it back.

Bei Mingyan was a little confused, what did he do just now?Just finished it, and was ruined by yourself?

Duanmu Wei was speechless at first, but seeing the little senior brother's rare overwhelmed look, she found it quite funny.

"Hahaha... Brother Yan, you ruined what you made. Haha..."

Bei Mingyan sighed and said:
"I, I just wanted to draw it. I didn't expect it to be like this."

Duanmu Wei laughed and said:
"With this ruler, you can only use this quill pen I made. Try this again, isn't there still a part that is not broken?"

Bei Mingyan really imitated the way the little junior sister used the quill pen, lightly tapped in the inkstone, and then drew along the edge of the ruler. This way, it is really possible.And the drawn lines are thin and straight.

Also referring to what the little junior sister said, he drew a complete square frame.The junior sister said that this is called a square.Because it is square, it looks like this from any side.

Starting from this square, Bei Mingyan was full of expectations for the geometry and mathematics that the little junior sister said.

He wanted to understand what the little junior sister said about going from point, to line, to a plan view, and then to a three-dimensional view.But I also know that I have to learn bit by bit.Every day the junior sister taught, he took notes carefully.
