Official road bends

"Yi Shao, where are you going?" Qian Duo knew that Li Yi would definitely not go home first, so he asked. .

"Go to my uncle." Li Yi said in a deep voice.

He is now eager to identify the materials that Brown handed over to him. Is it true, is it valuable, and how much is it worth?

The fastest way to identify these things is to ask uncle Li Zhengyu for help.

When I came to the uncle's house, I didn't see Li Zhengyu and his wife, only Li Juan was at home.

Li Juan opened the door for Li Yi, and said with a smile: "Brother Li Yi! You came just in time. I don't know how to do some homework. You teach me."

Li Yi said: "You are not a primary school student, nor a junior high school student. I may not know your homework."

Li Juan said with a smile: "You will definitely! If you don't, no one in this world will. Come and teach me."

Li Yi asked, "Where's your father?"

"I don't know, who cares about him! Anyway, I can't lose it." Li Juan said, and pulled Li Yi into her room, asking Li Yi to teach her homework.

These are some advanced mathematics questions.Of course, for Li Yi, it's just pediatrics.

"You have to learn how to solve problems first. If your thinking is wrong, you can't solve these problems. Whether it is a function problem or a geometric calculus, there is a way to solve the problem."

"I don't understand! The teacher didn't teach us what kind of thinking to use to solve the problem."

"Don't you teach you ideas?" Li Yi asked back.

"They don't teach! They only teach formulas, and then they come up with questions and test papers, asking us to practice more!"

"You should practice more. Practice makes perfect. The idea of ​​solving the problem is also summed up from the practice."

"I don't know how others are, anyway, the more I practice, the more stupid I become!"

Li Yi laughed and said: "The more you practice, the more stupid you become? Then your book is interesting to read!"

Li Juan said annoyedly: "I'm not a mathematician, what's the use of learning these things?"

"In the future, when you work, it will inevitably be useful."

"Even if I work, I will never find a job related to mathematics! I hate mathematics the most! I never knew how memorizing these formulas and memorizing these question types will affect my future life! My father I don’t understand these things. He can’t even do our math homework. Isn’t he still a high-ranking official? , I don’t even need to know this knowledge, I will at most be a sesame seed worker in the future, is it useful to learn this?”

Li Yi was left speechless by this sister's question.

What is the education we received from childhood?

Adults often say that life has a limit, but knowledge has no limit. We should devote our limited life to unlimited learning.

But what should we learn?

It seems that we have no choice.

Just as Li Yi thought of this, Li Juan also thought of it. She complained and said: "From kindergarten, or even from the moment we landed, our education has basically been stereotyped. After we entered school, the education we received Knowledge is stereotyped. Textbooks are certain, knowledge is certain, and content is also certain. Whether it is useful or not, and whether we like it or not, we must learn, and we must learn well! He was scolded by the teacher, and when he got home, he had to be disciplined by his parents!"

"Textbook knowledge has been carefully discussed and selected by many education experts." Li Yi hadn't considered this issue deeply before. Now, in order to answer Li Juan's doubts, he had to make up a temporary sentence: "To learn authoritative knowledge, we are exploring On the road, you can avoid a lot of detours.”

"So, does Li Bai also learn functions? Does he also know how to solve problems in geometry?" Li Juan asked sharply.

"Well, he probably won't." Li Yi scratched his head.

"There were also mathematicians in ancient times! The Pythagorean theorem was invented by the ancients in our country more than 1000 BC. Why didn't Li Bai and Du Fu learn these things?"

"This!" Li Yi was a little short of words: "The textbooks of that era did not stipulate that everyone must learn these things, right?"

"That doesn't prevent them from becoming great poets and writers!" Li Juan said: "If Li Bai has been studying our courses from the age of three until he graduated with a Ph. If he is troubled by geometry problems, and sacrifices the time to go to the bathroom in order to memorize English words, can he still become a great poet?"

Li Yi was completely speechless, he didn't know how to answer Li Juan's questions at all.

"Maybe, he will become an excellent mathematician, and possibly, an excellent translator." Li Yi could only answer in this way.

Li Juan said: "However, our country does not lack outstanding mathematicians, nor does it lack excellent translators, and there is only one poet, Li Bai, in a thousand years!"

Seeing that Li Yi didn't answer, she said again: "Also, does Wang Xizhi study mathematics? Does he study English?"

"English is definitely not learned, math? I don't know if he understands, basic mathematics, he should understand." Li Yi smiled and said: "Otherwise, how does he know how to plan the layout? Calligraphy works Inside, it also implies geometric principles.”

Li Juan said: "I think that the education Wang Xizhi received from childhood would never be as complicated as ours! Otherwise, his handwriting would not be so good! I heard that in order to practice handwriting, he gave his wife steamed buns to him, so that he could have a good handwriting. Ink to eat! If I think about it, as long as a person concentrates his whole life on one thing and does it well, then his achievements will be remarkable.”

Li Yi said: "If there are enlightened parents in the family, or parents with special skills, the children will be instilled in them to learn various special skills. In addition to normal studies, they can also develop their own specialties! Like Li Bai, if he likes If you write poetry, you can use your spare time to study poetry and write poetry!"

Li Juan said: "I don't know how other people are. Anyway, I don't have much spare time. Even if I want to go to your house to play, I have to find time! I am much busier than my dad! Let alone develop any hobbies." gone."

Li Yi couldn't help feeling a little sympathetic to her: "Then what are your hobbies?"

Li Juan said: "My greatest sorrow is here. I don't know what hobbies I have at all. Because I have never been trained in any hobbies since I was a child. I don't like painting, calligraphy, etc. I don't like playing the piano or flute. I don't want to learn either."

Li Yi said: "That's because you didn't try, and you didn't seriously think about your inner needs. You can try to do it, find your hobbies, and then squeeze out time to study and practice, and you will eventually develop. Come with your hobbies."

"But, I don't have time."

"Time is like a woman's chest, squeeze it, there will always be." Li Yi blurted out, and then thought that in front of him was his younger sister, a girl in the puberty stage!

Fortunately, Li Juan's mind was full of endless homework and endless points, and she didn't think carefully about the profound connotation of Li Yi's words just now.

"Li Yi is here!" Li Zhengyu and his wife entered the door at the same time. They ran to their daughter's room to inspect as usual, and saw Li Yi.

"Uncle!" Li Yi shouted, "I have something to tell you."

Li Zhengyu hummed: "Speak in the study."

Li Juan said: "Hey, there are two more questions, and you haven't taught me how to solve them yet!"

Li Yi waved his hand without looking back: "Think about it first, and I will teach you later."

Li Zhengyu said: "This child is always pestering me to teach her homework - how can I do it? Her mother can't either! These homeworks are really difficult now, anyway, I can't understand them."

Li Yi chuckled: "That's because the students of your era didn't learn these knowledge points."

Li Zhengyu said: "Is it really useful for children nowadays to learn so many things? Although it is said that many arts are not overwhelming, but things that are memorized by rote, or things that they are not interested in, have to wait for the exam. Can they really remember?"

Li Yi said: "I finally know why Juanzi loves to ask why so much. It turned out to be inherited from you, uncle."

Li Zhengyu was taken aback for a moment, then laughed out loud.

When he came to the study and sat down, Li Yi went straight to the point, took out the few materials that Brown gave him, and handed them to Li Zhengyu: "Uncle, take a look first, are these things useful?"

Li Zhengyu took it, took a few glances, then reached out to pick up the reading glasses on the table, put it on the bridge of his nose, and looked carefully.

Li Yi saw that his uncle was looking so attentively, so he asked, "How is it, uncle?"

Li Zhengyu's face became excited: "Xiao Yi, where did you get these things?"

Li Yi didn't talk about the origin first, but asked: "Uncle, are these things really useful? Can you understand?"

Li Zhengyu smiled and said, "Are you kidding uncle that I don't understand English? Hehe, you asked me to read the original English works of Shakespeare. I may not understand it, but I can still understand a little bit by looking at these engineering drawings. Practice makes perfect Well, I usually come into contact with a lot, and being forced, I have no choice but to study by myself, and understand all the terms and English that I often come into contact with.”

Li Yi praised: "Uncle is really a model of living and learning."

Li Zhengyu said: "A person's truly useful knowledge is accumulated in work and practice."

Li Yi asked: "What are these materials related to?"

Li Zhengyu said: "This is a treasure! This is an important research material for the spacecraft! No, it should be said to be the original design!"

"Worth it?" Li Yi asked.

"It's so valuable!" Li Zhengyu said with a smile: "I've been investigating and researching my country's aerospace industry recently, and some of the bottlenecks I've encountered now are mentioned here."

Li Yi said: "So, these materials are really useful?"

"It's so useful!" Li Zhengyu's eyes lit up: "Xiaoyi, tell me quickly, where did you get these treasures? Are there other parts? There is only one part here! It's not comprehensive, so it's just Not much reference value.” (To be continued.)
