Scholar’s Starry Sea

"We’ve talked a little bit, let’s go back to the competition."

Bi Wanqing walked back to the blackboard and picked up the chalk after finishing talking.

[Mentality]

"The Physics competition is just a game. It is to compete with students from other schools and provinces. No one is afraid of anyone, but don’t hold it. I have to take a gold medal to recommend the mentality of Jinghua Jinghua. After all, no matter how powerful students are, they dare not pack up to get the first place."

Speaking of Bi Wanqing paused, I corrected it: "It should be said that most Mathematics students, um, overwhelming majority."

This sentence...There is a story.

'It seems that there is really a kind of scholar who knows that he will win the championship before participating in the competition. 'Wu Bin thought to himself.

"You started too late, and the sea tactics are definitely useless for you. Otherwise, I have a lot of infrequent books that can help you expand your knowledge, and it is very likely to hit the problem."

"It's not too late, teacher! Just show me, I read books quickly." Wu Bin immediately raised his hand and said excitedly.

"hehe, well, if you want to see me, I will bring it to you tomorrow, but the premise is that you first read the books of Teacher Cai to you, and those are the big heads."

"Okay, I see."

[How to solve the problem]

Bi Wanqing wrote four big characters on the blackboard as he spoke.

"Most of the papers only need to be done once, and you will know the approximate method of solving each problem. For example, if you want to use an equivalent power supply to solve the problem, don't use Kirchhoff's law to calculate."

After speaking, Bi Wanqing suddenly drew a picture on the blackboard, patted his hand, and looked towards Wu Bin: "This is a space force problem in the Jiang Sixi Special Topic. The average student just read it. At that time, they will be confused, and when they can’t find a clever way to solve the problem, they can only use three-dimensional analytic geometry to calculate.

"But in fact, there are many details in the problem, such as the charge surface density. Two sides..."

Listening to Bi Wanqing lecturing himself, Wu Bin felt that it sounded quite easy to accept. Some of the problem-solving steps and thinking details were explained in detail, just like this teacher just now. As I said, I can always scratch the itch.

'This is very comfortable!'

Then Bi Wanqing talked to Wu Bin a lot about his game experience.

For example, "Many papers always have unclear expressions because the language of Physics experts is taught by Physics teachers. "

"In addition to the text, the model of some questions is unclear. Even if you figure it out, the teacher might not be able to figure it out. "

"How to say it, just like reading and understanding the concept, sometimes the original author's answer is useless.

"Typical examples are all kinds of soft, elastic, inelastic, non-stretchable ropes, or capacitor leakage, or the electric field energy density in the capacitor, etc."

In After writing a whole blackboard, Bi Wanqing looked at Wu Bin's still bright eyes and smiled.

"Teacher Cai really didn't say you wrong."

"Well? What did you say?"

"Speaking of new knowledge is just for you It’s the same as the new toy. Actually, the questions I just told you about should be something you haven’t touched yet. Generally, students will feel boring and boring when they hear the questions they’re not good at, but you’re different. You listen to them from beginning to end. It’s very serious."

"Because I still know the basic concepts of these questions, and the teacher you said is very exciting, very good, anyway, it is the operation explanation of Thieves 6, a handsome group."

p>

"hahahaha, I don't understand you children's strange things, anyway, you should be complimenting me, right." Bi Wanqing said with a big smile.

"That must be more than praise. I admire you too much. Your topic level is absolutely world-class." Wu Bin gave another big thumbs up.

"Well, good, you like to listen, oh, it seems a bit late, you haven’t eaten yet."

"It’s okay, Teacher Bi, I’m not hungry, you Go on...Russia, did you not eat the teacher? How about the teacher go to eat first."

Wu Bin still wants to continue listening, but he can’t let the teacher teach him hungry. .

Looking at Wu Bin's reluctant eyes, Bi Wanqing walked down and patted his shoulder said with a smile: "Why don't you go to the teachers' cafeteria with me to eat."

"Good, good." Wu Bin nodded quickly agreed.

"Let's go, then."

The two teachers and students soon came to the teachers' cafeteria. Students can't come here by themselves, but the teacher can bring them.

"What do you want to eat?" Bi Wanqing took out his meal card and asked Wu Bin.

"Oh, no, Teacher Bi, I just buy it myself."

"Don't be polite with the teacher, just treat it as... well, just like you boast Teacher’s reward."

"This..."

"Oh, which student is so powerful, praise you, you have to invite him to dinner." At this time, a platoon A male teacher in front of the two turned around and said in a joking tone.

Wu Bin glanced at the teacher, but did not recognize which teacher it was from.

"It's Xiao Song teacher, I just ate it." Bi Wanqing smiled and said hello to the teacher, and then introduced Wu Bin: "This child has just entered the competition group, which is very interesting. , I have been teaching for so long, and he is really the only student who praised me for being happy."

"Haha, is it." Song teacher smiled and glanced at Wu Bin, "Hey? This? Child seems to have never seen it in the competition group before."

"Well, it’s the first time to participate in the third year of high school."

"It’s the first time in the third year of high school? Oh~~I know Now, this child is the dark horse of Cai Guoping's class. Suddenly he got a full score in the exam. It can be promoted in the past two days." Teacher Song thought about it.

"Yes, this is the child."

"There is a future, keep working hard, then Teacher Bi, you guys talk, I will go there for dinner first." Song teacher took Said the meal just finished.

"Okay." Bi Wanqing moved towards his nodded, then turned to look at Wu Bin and asked: "Is there anything you want to eat?"

"Just...just tomato scrambled eggs Let's braise eggplant."

Wu Bin came to the teachers' cafeteria for dinner for the first time, and found that the dishes here seemed to be better than those in the student cafeteria, but he was also sorry for the expensive ones.

"Where is vegetarian food enough? When you grow up." Bi Wanqing said, swiping the card and said to the cafeteria Aunt: "Make a portion of braised lion's head, and then a portion of Red Braised Pork. "

"Okay~teacher is right. For a long body, what can I do if I eat less? Aunt will give you more."

It is also rare for Aunt to see students in the cafeteria. Came here to eat, the amount given was very sufficient, a large plate of Red Braised Pork was almost overflowing.

"Thank you Aunt." Wu Bin said after taking the dinner plate.

"No thanks, no thanks, come on studying."

After Bi Wanqing finished his meal, he led Wu Bin to a table where no one was sitting.

The two teachers and students had a great time talking while eating.
