Chapter 94 The Importance of Difficult Problems

"Wow, it's snowing."

"Really! It's snowing, it's snowing."

"Do you think it can be accumulated this time?"

As Tang Xinhan, who was sitting by the window, said, "It's snowing." Almost the entire class three students crowded to the window and burst into cheers.

In Shanghai, these hexagonal ice crystals have always been a rarity, and many young people who are out of breath due to the fast pace of the city always smile knowingly when they see them.

Looking at Gu Fan who was watching the snow as excitedly as the others, Wu Bin patted him on the shoulder and asked: "Hey, what is the phenomenon of snow called in physics?"

"Damn... you're poisonous, can't I just watch the snow quietly for a while?" Gu Fan turned around and said with a pained face.

"So, what's happening?" Wu Bin asked again with a smile.

"Ninghua is a phenomenon in which matter jumps from the liquid state directly to the solid state." Gu Fan replied helplessly.

"Yes." Wu Bin nodded with a smile, and then suddenly said sharply: "I know Ninghua, you did the wrong question on the tungsten question last time!?"

"Brother, why don't you be so spartan...I just took a look at the snow." Gu Fan suddenly lost his confidence.

"I just mocked you once."

And just when Gu Fan rolled his eyes and was about to retaliate, Xu Bo suddenly ran over and said, "Wu Bin, are you free now?"

"What's wrong? Do you want a question?" Wu Bin turned around and asked.

"No, please come out for a moment. I have something to ask you."

"Mysterious... okay." After saying this, Wu Bin stuffed the book into the table and followed Xu Bo out.

Arriving at the end of the corridor, Xu Bo looked at the snowy scene outside the window and suddenly took out a pack of spicy sticks and said to Wu Bin, "Want one?"

"I'm offering spicy strips for nothing. If you don't say anything, I won't dare to eat them." Wu Bin shook his head and said.

"Actually, it's nothing, it's just... you've become very familiar with Pei Jiamin recently, can you help me ask... what does she like?"

"That's it? Okay, I'll ask you about it later." When Wu Bin heard that it was such a trivial matter, he smoked a spicy stick and ate it with confidence.

"Then thank you in advance!" After saying that, Xu Bo stuffed the whole bag of spicy strips into Wu Bin's hand, "This pack of spicy strips is considered a deposit, and I will thank you again after the deal is done!"

After saying that, he ran back to the classroom like the wind.

"As for that." Wu Bin chewed the spicy sticks and returned to the classroom.

…

At the end of the fourth period in the afternoon, Wu Bin was preparing to go to the cafeteria with Teacher Bi as usual, but he met Su Yun in the corridor who seemed to have been waiting for a long time.

"Hi~" Su Yun waved towards Wu Bin.

"Hello, Teacher Su." Wu Bin shouted politely.

"Don't be so polite to me." After Su Yun finished speaking, she took out a folder from behind and handed it to Wu Bin: "Nuo, you are going to participate in the national competition soon, right? I got this from a senior brother. It should help you."

"Is it a book?" Wu Bin asked curiously.

"You'll know when you see it." Su Yun's tone was a little proud.

"Then, thank you, teacher." Wu Bin said and took the folder.

After opening the folder, Wu Bin only took a few glances, and his eyes immediately lit up with surprise.

The folder is full of very difficult physics problems, and the angles of the questions are very tricky, and the excitement is definitely no less exciting than any problem set he has ever done.

"How's it going? Not bad, right?" Seeing Wu Bin's surprised expression, Su Yun's voice became even more proud.

"This is simply amazing. Teacher, what does your senior brother do?"

After so many hours of competition training, Wu Bin deeply understood the preciousness of "hard questions", so they would discuss each real question Bi Wanqing found for him many times because there were only a few of them.

At the same time, he also understands that a teacher who can solve "difficulties" is very valuable. It can even be said that this is one of the biggest differences between competitive schools and ordinary schools.

To put it bluntly, those teachers who can come up with questions from various tricky angles to embarrass you are worth cherishing, because others don’t even have them!

"Secret, in short, this will be very useful to you." Su Yun said with a wink.

"This is very useful, thank you teacher." Wu Bin nodded, but his eyes did not leave the topic at all.

"Then, the teacher also wants to trouble you with something, can you help?"

"Of course, students should help teachers."

"Haha, I know you know the truth best. Then come to my office during lunch break tomorrow and I will tell you what happened." After saying that, Su Yun stretched out her hand and waved it in front of Wu Bin who was reading the question: "Hey, did you hear that?"

"I heard it, I heard it. I'll remember it during lunch tomorrow, right?" Wu Bin nodded again after saying that.

"Okay, then I won't delay you in reading the questions. Let's go now."

After saying that, Su Yun snickered looking at Wu Bin's increasingly excited expression and slowly walked down the stairs.

…

As soon as Su Yun left, Wu Bin immediately rushed up to the fifth floor with the folder, opened the teacher's office door and shouted: "Teacher Bi!"

"What's the matter? I'm so excited today. What's delicious in the cafeteria?" Bi Wanqing responded cheerfully.

"No, no, look at this." After Wu Bin said that, he spread the folder in front of Bi Wanqing.

"What makes you so excited?" Bi Wanqing put on his eyes and looked at the questions in the folder in front of him.

"Where... did you get this?" After reading the first question, Bi Wanqing asked Wu Bin in surprise.

"A teacher gave it to me. Isn't it very good? The first two mechanics questions are so interesting." Wu Bin said with excitement on his face.

"It's indeed very good. A teacher who can give such a question is of high standard." Bi Wanqing nodded with certainty.

At this time, Deng Xiuqin, who was about to go to dinner, couldn't help but came over out of curiosity and said, "What are you two talking about, master and disciple? What question is so interesting?"

"That's it, Teacher Deng." Wu Bin said, pointing to a mechanics question on the folder.

"Come on, let me take a look too." Deng Xiuqin said, leaning her head forward and looking at it seriously.

"Ouch, this question is indeed very misleading, but it shouldn't be a problem for you." Deng Xiuqin patted Wu Bin and said.

"I now think of treating the two-body collision as a degenerate elliptical motion. I have to list the formula first and then calculate it later."

"It's not that simple."

Deng Xiuqin smiled and walked away, leaving Wu Bin confused.

"Am I wrong in my approach to solving the problem?" Wu Bin said in disbelief.

"Hahaha, Teacher Deng is scaring you, that's what she likes." Bi Wanqing said with a smile.

But just when Wu Bin was about to laugh along, Deng Xiuqin suddenly said: "There is really a more cunning way to solve this problem. You two are still studying physics. Think about it carefully. I'm going to eat first." Then he walked out of the office with a smile.

At this time, the smile on Bi Wanqing's face disappeared, and he followed Wu Bin and stared at the question.
