Lin Cheng can also understand the problems encountered by the mathematics enthusiast in front of him.
After all, the other party is just a high school math teacher. In terms of level, he is indeed quite different from a university professor.
There are many papers, but with his channels and information, he may not be able to find them.
Lin Cheng glanced at the old man and said calmly: "If you are really interested in the four-color conjecture, I suggest you find a copy of the "Annual of Mathematics" half a month ago. In that issue of "Annual of Mathematics" , published an article by Academician Li Zhongnan of Beijing University. In that article, it clarified in detail how the four-color conjecture is proved at the level of logical relations and two-dimensional inherent properties. It is suitable for beginners to understand the entry , Academician Li Zhongnan's article is much more reliable than that so-called Spanish professor."
Hearing Lin Cheng's description, the old man immediately asked excitedly: "Little brother, are you sure it is the "Annual Journal of Mathematics"?"
Lin Cheng nodded.
Hearing this, the old man immediately jumped three feet high, and said excitedly: "That's great, I have the "Annual of Mathematics" from half a month ago at home, and I'll go get it now."
After finishing speaking, he ignored everything, turned around and ran back to the house.
Seeing his father like this, Qu Yang suddenly felt a little embarrassed.
He said to Lin Cheng with a wry smile, "I'm so sorry!"
Lin Cheng shook his head quickly, and said: "Actually, at this age, it's good to have some hobbies. What's more, studying mathematics can stimulate brain activity, thereby reducing the chance of triggering Alzheimer's disease, which is a good thing."
Hearing what Lin Cheng said, Qu Yang couldn't help laughing, and said, "It seems to be true!"
"Found it! Found it!"
At this moment, the old man rushed out with a magazine and shouted loudly at the same time.
Seeing his father's actions, Qu Yang's heart trembled uncontrollably, for fear that his father would fall to the ground.
The old man came to Lin Cheng with the magazine, and said gratefully: "Little brother, thank you so much. If it weren't for your reminder, I guess I'm still struggling with that Spanish paper!"
"It's nothing, as long as I can help you, old man, I will be satisfied. By the way, old man, what is this? Is it the problem you are studying now?"
Suddenly, Lin Cheng pointed to the bottom page of the stack of materials and asked.
Hearing Lin Cheng's inquiry, the old man said with some embarrassment: "I'm not interested in mathematics? So I found a few difficult mathematical problems on some materials and wanted to solve them by myself. Unfortunately, I still I underestimated the difficulty of these math problems, and if I didn¡¯t look at the specific steps to solve the problems, I couldn¡¯t even think of a way to solve the problems, I¡¯m really ashamed!¡±
Hearing this, Lin Cheng smiled and comforted him: "Old man, don't be discouraged. The math problems you selected are representative problems, and the difficulty is not as low as you imagined. Let alone you, even some math problems Even the professor may not be able to solve it smoothly."
"Really?" the old man asked back.
Lin Cheng nodded.
Seeing that Lin Cheng was comforting his father there, Qu Yang had a strange look in his eyes.
This scene made him feel unspeakably weird!
If it weren't for the yellow Meituan uniform that Lin Cheng was wearing, he would even think that it was a professor from a prestigious university who was comforting his father. -
This kind of picture is really full of incongruity.
What surprised him was that his father, who had been a teacher all his life, was no different from a student in front of Lin Cheng.
Although he didn't say anything on the surface, there were turbulent waves in his heart.
Is this young man in front of him really a delivery guy?
When did the delivery guy become so demanding?
Not only is he proficient in Basque, but he also has research on the most popular mathematics problems at present, and he can even tell the specific content of many mathematics papers. Such a delivery boy is too evil, right?
Even if he is a doctor of linguistics, standing in front of Lin Cheng, he still feels a little Alexander.
"Meituan Food Delivery has automatically accepted an order, and you have a new takeaway order."
Suddenly, the voice of Meituan automatically accepting orders rang out on Lin Cheng's mobile phone.
Lin Cheng got up straight away, and said to the two of them, "Both of you, I still have work to do, so I'll be leaving first. In addition, I would like to thank you both for your hospitality."
It was not easy for the old man to meet such an interesting and proficient in mathematics.Man, he originally wanted to keep Lin Cheng at home for dinner, but when he thought that Lin Cheng still had work to do, he finally had to give up his idea and watched Lin Cheng get up and leave.
"Little brother, wait a minute."
Just when Lin Cheng was about to leave, Qu Yang suddenly stopped him.
Lin Cheng froze for a moment, and said, "Is there anything else you can do?"
Qu Yang quickly took out a bottle of iced Coke from the refrigerator, handed it to Lin Cheng, and said, "Drink it on the way."
Lin Cheng took the Coke, smiled slightly, and said, "Thank you."
After finishing speaking, he turned around and prepared to leave.
But at this moment, Lin Cheng seemed to have thought of something, he turned to the old man and said, "Uncle, if you still can't solve the problem just now, you might as well change your thinking to solve the problem and use McLaughlin's formula try it."
After speaking, he nodded to Qu Yang, opened the door and left.
Seeing Lin Cheng leave, Qu Yang originally wanted to call his father to move the beer away, but when he was about to speak, he found that his father was standing there blankly, as if in a daze, and his mouth was even more It is constantly chanting: "McLaughlin's formula, McLaughlin's formula"
Seeing this temperament, Qu Yang asked with some concern: "Dad, are you okay?"
It's a pity that the old man didn't pay attention to Qu Yang, and kept chanting the same sentence in his mouth.
As time went by, every time the old man said a word, his eyes lit up.
At the end, the old man showed ecstasy on his face, and said, "That's right, it's the McLaughlin formula, that's it!"
After finishing speaking, like a madman, he picked up a pen and began to write something frantically on the piece of paper.
Seeing his father like this, Qu Yang was also a little silly.
Although Dad was also obsessed with mathematics in the past, he was not as crazy as he is today!
After about five minutes, the old man finally dropped the pen in his hand, picked up the piece of paper at the same time, and danced excitedly.
At this time, the old man was as excited as a child.
Seeing his father like this, Qu Yang asked with some concern: "Dad, are you okay?"
Hearing this, the old man laughed loudly and said, "Of course it's okay. I've never felt as good as I am now. Sure enough, I'm right that I like mathematics. This subject is really fascinating. A simple formula , unexpectedly made this question so simple all of a sudden. Qu Yang, where is that kid? I want to thank him, he is simply my teacher!"
"Dad, hasn't that takeaway boy already left?" Qu Yang said directly.
Hearing this, the old man just woke up like a dream, and at the same time he said with some complaints: "How can you let him go?"
Qu Yang was speechless when he heard the words. (Remember the site URL: www.hlnovel.com - Didn't finish reading? Add this book to your favoritesI'm a member and bookmarked this chapterCopy the address of this book and recommend it to your friends for pointsChapter error? Click here to report
