Go back to the past and be a schoolboy

Chapter 86 Sir, I know eight characters as many as the palm of my hand

Beiping City, Cheng Family Courtyard.

The children were standing on tiptoe, holding onto the window sill of Cheng Nuo's office to look inside. Since they were of different ages and heights, some could see it, while others were anxious.

Seeing this, Wen Cong supported his sister and made her stand a little higher, and now the injury has completely healed, and said: "Huihui, can you see clearly now, have you seen that thing that Mr. often holds. "

Goudan'er got some saliva and wiped the window brighter: "Sister Wenhui, you have to read the name of the book clearly. Let's save money and go to the bookstore to buy a copy. Then we can read it together."

Nidan'er leaned against the wall, her face lacking in interest: "Why don't you believe it? It's not because there are some secrets for being so powerful. It's because the more books he reads, the more he knows. Just like what our teacher said If you read the book a hundred times, you will see its meaning."

Goudan stared and pointed his sister's forehead with his finger: "You little girl knows a lot. Next time the teacher punishes me for copying books, you can help me. It just so happens that you can learn more."

Nidan hurriedly wiped the spot that was touched: "It's so dirty, I can tell my mother whether I will tell her when she comes back to see her. Anyway, peeking at Mr.'s things is wrong."

Goudaner was unconvinced: "Who said it was stolen, we just want to see it, and after we file a complaint, you can eat the candied haws regardless."

These children saw that Cheng Nuo's room was closed and had no chance to go in on weekdays, and they were all as powerful as Mr. Cheng. They thought that there must be something powerful in the room, as precious as in the drama, and their intuition told them that it was A book that Cheng Nuo often takes.

So out of a child's mentality, I wanted to see what happened through the window. I didn't have the guts to steal it, but I still had the heart to save my pocket money. If it didn't work, I could still sell newspapers, push carts, and shine shoes. There is a way to save slowly.

"Brother, I see it clearly. The name seems to be "Mathematical Dictionary". Have you heard of this name?" Wen Hui felt sorry for her brother, and wanted to get down immediately after speaking.

Wen Cong carefully put his sister down, and asked, "Are you sure you read it right? It's called "Dictionary of Mathematics". It seems that I have never heard of this name before. He must be right."

Goudan'er has only been studying for a few days and doesn't know much. Seeing what the two brothers and sisters said, he believed it in his heart: "Yes, it should be it. I'll go to the bookstore tomorrow and ask how much it is. Good number."

At this time, a familiar yet unfamiliar voice suddenly came from behind: "What are you doing? Did you see any treasures? I'll take a look too."

As he said that, the man also lay down on the window sill and looked inside through the window, looking very curious.

The children turned around and saw that it was Cheng Nuo himself, who was lying on the bed with them now, and their souls were scared to death.

"Sir, I'm sorry, I didn't know you were coming back, or we wouldn't dare."

As the eldest brother, Goudaner is also the "principal culprit". He took the initiative to stand in front of his younger siblings, bowed his head and stretched out his hands, as if he was willing to punish him.

Cheng Nuo almost couldn't hold back his laughter when he saw it, it was so familiar, he was so playful, he clenched his fists and raised them high, scaring the children to close their eyes tightly, fearing that a "tragedy" would happen.

Even Goudaner, who has always been daring, closed his eyes tightly when he saw this. His mother was not so afraid when he was beaten by his own mother.

What he didn't expect was that Mr. raised his hand high, put it down gently, and secretly opened a slit, and found that there were a few small bumps wrapped in paper in the palm of his hand, colorful and beautiful, but never never seen it.

When Mr. Wang noticed it, he immediately raised his neck and closed his eyes tightly.

"Okay, Goudaner, don't pretend, just open your eyes. This is the candy I brought you from the Shanghai market. Try it and see how it tastes."

Seeing this, the children immediately came over yelling, waiting for Cheng Nuo to share the candy with them, and when they tasted sweet, they felt that they were getting closer to their husband.

"How is it, is it delicious?"

"It's so sweet, sweeter than stove sugar, thank you sir."

However, Cheng Nuo did not forget his task. He led the children into the house and introduced the mathematics dictionary, and said that when it was published in the future, he would give each of them a copy, and encouraged them to study hard. look for him.

Watching the children go away, Cheng Nuo picked up the dictionary in his hand. Although it was only a first draft, it was too bulky. It is a good teacher and helpful friend for professional mathematics practitioners, but for these students who are new to mathematics, On the contrary, it is not conducive to searching and reading. When you see such a thick stack, you may retreat.

When I came to the front yard, I found the temporary office of the School of Mathematics, where several people were editing books.

"Come on, everyone, you have worked hard. This is the special pear paste candy I brought from the Shanghai stock market. I have been busy these days. Take it for a share."

Yan Jiaxuan, who was still bowing his head to proofread, raised his head, and when he saw Cheng Nuo coming back, his face was full of surprise: "Principal?! When did you come back, you miss us so much."

Ma Minghai, who was about to drink water, stopped immediately, ran over and said with a smile: "My dear dean, you still think that we still have a school of mathematics and science, I thought you ran away with the funds and your sister-in-law. "

"Fuck you, my wife is gone, where is my sister-in-law, share the candy with everyone, and shut your mouth." Cheng Nuo scolded with a smile, and handed over a large bag of pear paste candies.

These two people are the backbone he invited over, both with a master's degree, one is from the same school as Harvard University, and the other is from Columbia University. Their knowledge is very solid, and these people often joke with each other when they gather together on weekdays.

In private, everyone has a good relationship, but when it comes to work, one is more serious than the other.

Cheng Nuo picked up the "Dictionary of Mathematics" that had been proofread twice on the table, looked through it for a while and said, "Everyone has done a good job, especially after briefly sorting out the history of mathematics at home and abroad, I am very happy." Surprise, it's time to contact the publisher."

Yan Jiazuo said seriously: "Dean, I think our sample questions are not clear enough. I plan to simplify them later, and strive to provide detailed explanations or proofs for every important knowledge point."

Ma Minghai then said: "Yes, in addition to what Lao Yan said, some well-known mathematical conjectures that have been proven or unsolved, I am also going to add them, such as your Kronecker's youth dream, I am also thinking about what to do form into it.”

"Kronecker's dream of youth can be put into the part of number theory, just a brief introduction, and there is no need for a long speech." Cheng Nuo sat on the seat, put the books on his lap, and said with a smile: "But this way , our "Dictionary of Mathematics" is probably too much to put down, and we have to change the name to "Dictionary of Mathematics", and the few of us here may not be able to finish it in a year or two."

"So what is the dean's opinion?"

"My opinion is that you don't need two if you can fit one book. The name is changed to "Concise Dictionary of Mathematics". Just like his name, you only need to introduce its concepts in easy-to-understand language. If readers want to learn more Just add the name of the professional book on the side.”

"But in this way, the sense of thickness of our book will be greatly lost. I am afraid that the effect may not be good."

Cheng Nuo slid down from the table and said, "On the contrary, we should have less heaviness and more popular science. Remember that our book is used to lower the threshold for readers to learn mathematics, not to increase trouble. Just a few pages can't replace professional books."

Under his arrangement, the work of "A Concise Dictionary of Mathematics" is simplified, and the main targets are primary and middle school students. The content includes arithmetic, algebra, plane geometry, solid geometry, plane trigonometry, plane analytic geometry, spatial analytic geometry, probability, statistics, There are more than 2000 common entries in logic algebra, etc.

And considering that many students may drop out of school halfway, I simply added a chapter on the content of abacus, and attached its mental formulas. Craftsmanship that allows them to eat.

But in this way, although the overall content needs to be greatly changed, the main work to be done is mainly streamlining, which is much faster than before.

After instructing the plan, Cheng Nuo was about to leave the courtyard when he happened to bump into Li Laosan.

I haven't seen him for a while, Li Laosan's face is darkened a lot, but his spirit seems to be better.

"Sir, when did you come back? Why didn't you inform me? I'm going to pick you up at Qianmen Railway Station too. I'll let you travel so far."

"Hey, Lao Li, you don't even know me when I sent you a telegram. Why don't I just walk back and save trouble?" Cheng Nuo waved his hand and said casually. It's just such a short distance, just take a taxi and come back. There is no need to send a special telegram, that thing is charged by the word, which is not much less than the fare of the car.

Li Laosan smiled honestly after hearing this: "Sir, actually I know a few words. If you send another telegram, I will definitely know it."

Cheng Nuo said in amazement: "Yes, Shibai Sanri Li, you told me to treat me with admiration. Come, come, I will test you, and you can write your name for me."

Seeing this, Li Laosan happily picked up a piece of dirt in the yard, and wrote his name stroke by stroke on the ground.

Although the characters are crooked, the words "Li Laosan" can be vaguely seen, and it seems that he really knows how to write his name.

Seeing this, Cheng Nuo couldn't help but punched him in the chest: "Old Li, you are really good at it. When I go out again, can you surprise me again and tell me how you learned it. "

Li Laosan threw away the soil, patted the soil on his hands and smiled honestly: "Didn't you say before you left that I could be a husband if I planted a good land? Teach slowly."

After breaking his fingers and counting with his eyeballs upwards, Li Laosan smiled and said, "I can already have eight palms, and I will continue to learn later."

Through his smile, Cheng Nuo saw the green and black wheat seedlings in the yard. They were strong and strong, with well-developed roots. They were obviously as energetic as the owner.

This person, life is different when there is hope.

"Mr. Li, let's go, let's go to the Commercial Press!"
