Lin Banxia returned to the house, but the stones and the others had not returned.

The steward hurriedly stepped forward and said, "Miss Lin, I just sent an invitation from the palace, please come over tomorrow." ”

Lin Banxia took the invitation in surprise: "Did you say anything?" ”

She just left the palace today, is this to let her report every day?

"Say what kind of ruler it is." The steward didn't figure it out.

Lin Banxia nodded: "Got it." ”

It should be that the vernier caliper is a little eyebrow-raising.

Lin Banxia sat at the table, clicked the table, and remembered the problem of pi again.

The algorithm of pi, what Lin Banxia knows, is that the circle is connected with regular polygons to approximate the circle, or add the circle tangent regular polygons to find the average calculation.

Either one is very troublesome and troublesome, and Lin Banxia himself doesn't want to try it at all.

As for other methods of calculating pi, I'm sorry, Lin Banxia can't understand it, and I don't understand it either.

Just as he was pondering, there was a sound of laughter at the door: "Dad, mother, we're back!" ”

Xiaoshi ran in first, and when he saw Lin Banxia, he immediately stood down and said in a proper manner: "Sister, we are back." What about dad and mom? ”

Little Angelica also ran in from behind. Xiaohuzi walked very slowly and looked a lot more stable.

"All back?" Lin Banxia stood up, "Wash your hands and face first, and change your clothes." ”

The three little ones said yes and ran quickly to the backyard.

Lin Banxia continued to ponder pi. The pi of this era has been calculated to 3.14, let's just 3.14.

"Girl, is this going to be dinner?" The steward came up and asked.

"Wait a quarter of an hour." Lin Banxia commanded.

After Xiao Shi and a few people washed their hands and faces, and came out with homely clothes, Lin Banxia asked, "Is Mr. strict?" Did you listen to Mr.? ”

Xiao Shi hurriedly said: "Sister, Mr. gave me a new name, Lin Chengze, and my brother also has a new name, Lin Chengen." ”

Lin Banxia was happy: "Lin Chengze, Lin Chengen, good name, Mr. said he didn't say the meaning of this name?" ”

"Sir, let us remember that we are able to read today because we have received the favor of others, and we will be kind to others in the future."

Lin Banxia touched the head of the small stone and said, "Well said." Has Cheng Ze thanked Mr. ”

Xiaoshi nodded vigorously: "Thank you, kowtow to Mr." ”

Lin Banxia looked at the little angelica and said, "Angelica, has Mr. given you a new name?" ”

Little Angelica's voice was still a little milky: "Mr. said that my name is very good, and there is no need to come up with a new name." ”

Lin Banxia also touched Xiao Angelica's head, and finally looked at Little Huzi: "Huzi, do you like your new name?" ”

Huzi nodded: "I like it, Mr. told me that he wanted me to remember my sister's kindness to me." ”

Lin Banxia also touched Xiaohuzi's head: "Good boy, study hard with Mr." ”

I asked my husband what he had taught and learned, and then he led the three children to eat.

One day in the school, the three children obviously paid more attention when they ate, that is, Angelica, and they didn't say anything when they ate.

After eating, I told them that my father and mother were busy in the shop, and asked if they had any homework.

Knowing that everybody has to fill a big sheet of paper with strokes, and has to endorse books, I'm busy having people lead them to the study.

The children all left, so I called the people who followed me today and asked carefully.

Sure enough, it won't be easy to take care of the child, and after Lin Banxia asked, he had to go to the study to have a look.

Angelica is not as high as a table, standing on a chair to write, all over the paper is "horizontal".

The same goes for small stones, only the "horizontal" of Xiaohuzi still has a pattern.

Next, I listened to their endorsements and rewarded them with a sugar gourd.

After sending the three children back to the room, Lin Banxia returned to his room.

This day passed, and I didn't do anything I wanted to do.

But he's busier than in the village.

She was going to make soap.

But now even soybean oil and meat oil are not ready!

Never mind.

Lin Banxia threw himself on the bed, let's go to the palace tomorrow to do it, there is just free labor.

When he closed his eyes, he couldn't help but think of Xia Changyan staring at her in his mind.

Alas, it's a pity.

Lin Banxia turned over, hugged the quilt, and fell asleep.

Zhou Sheng's side, sure enough, he designed the prototype of the vernier caliper, which involved the marking of the size, and wanted to hear Lin Banxia's opinion.

The determination of measurement is not only related to people's livelihood, but also to the entire Great Xia.

Even Xia Changyan didn't dare to make a decision in private.

Lin Banxia didn't have those scruples, and even put forward the concept of "rice" with a playful mentality.

"Originally, I wanted to use the food character of food as a unit, but there are too many strokes of the word food, which is not as good as the strokes of the rice character.

And we can't do without rice in our daily food, so, Lord Wang, how do you think we use 'rice' as a unit? ”

Lin Banxia smiled and directly plagiarized the unit of measurement of the later generations.

Xia Changyan was still groaning, and Shen Cheng said first: "It's not impossible to use meters as a unit of measurement.

However, Lin Xiangjun, since the Qin Emperor unified weights and measures, the unit of measurement has always been measured by size.

Suddenly bring up this 'rice', I'm afraid it's ......"

Lin Banxia said: "'Meter' can be used as a separate unit of measurement, and it must be converted to the size of the meter. ”

Xia Changyan suddenly shook his head: "Ten inches is one foot, and ten feet is one zhang, it has become a law, and it can naturally be ten zhang or a hundred zhang upwards."

If you are marching and fighting, you are already accustomed to taking miles as a unit, and there are thousands of miles.

It is subdivided below the inch, and there are laws, but they are not commonly used.

We can subdivide it down, and this 'meter' can be measured below an inch.

How about ten meters as an inch? ”

Shen Cheng stroked his palms and said: "Your Highness's proposal is very good, in this way, you can further subdivide the inch into meters, although it can be divided again, but it can be determined by one-tenth of two." ”

Lin Banxia blinked, and this "rice" suddenly changed from so long to so short, if it collided with Western culture in later generations......

Maybe who's going to listen to whom.

Zhou Sheng also took the prototype of the vernier caliper, compared the size of the ruler, and marked it on it.

Sure enough, the caliper position is more subdivided.

This is outside of Lin Banxia's knowledge points.

Zhou Sheng and Shen Cheng studied for a while, and both of them stood in front of the blackboard.

Xia Changyan made a gesture of please and said, "Once these two people study it, it is easy to forget about the others, let this study room be given to them." ”

The two of them walked out of the study, Xia Changyan thought of yesterday's Qingsong poems, and his heart stirred again.

He was even more convinced that Lin Banxia must be in his pocket.

"I got a few horses from the north the day before, one of them is very docile, the weather is just right today, go to the carriage and have a look?"
