Lao Zhang and several teachers raised their eyebrows and came over in disbelief.
Has a student actually solved such a difficult problem?
I saw Zhu Ping'an excitedly pointing to a test paper. Under the mechanics question on the test paper, the answers were written in full and very neatly.
The most eye-catching thing is the final answer: it turns out to be the final answer 1/4ma.
At this moment, Lao Zhang and other teachers couldn't sit still.
What the hell, students can do this even if they don’t know how to do it. This is really shocking.
Lao Zhang didn't believe in evil, so he took the test paper from Zhu Pingan's hand and started looking at the answers bit by bit.
The answers and steps in front of you are neat and orderly. It is obviously the test paper of a good student!
On the side, Zhu Pingan looked proud.
"See, I say students are still smarter than teachers.
Otherwise, how can students pass the Qingbei exam? We can't, there are still geniuses!"
"Lao Zhang, Lao Zhang, don't waste your efforts here. What others have done is done. Why are you so stubborn!"
And just when Zhu Pingan was feeling triumphant, Lao Zhang next to him suddenly shouted loudly.
"Wait, come and see, there is something wrong with this problem-solving step."
"Although his final result was correct and he used quite a few formulas, the most critical step in the discussion was wrong and he jumped right over it!"
Hearing this, Zhu Pingan became anxious.
"Lao Zhang, you can't slander someone just because you lost a bet!"
As he spoke, Zhu Pingan also looked at the problem-solving process on the test paper word by word.
Just looking at it, Zhu Pingan was dumbfounded.
Because Lao Zhang is right, this problem-solving process is indeed imperfect!
The last and most critical step, the substitution proof of force, is skipped directly.
In other words, although the answer is correct, it is very likely that the student could not figure it out and finally guessed the answer by guessing!
Zhu Ping'an was discouraged at this time, and he had been looking for a genius for a long time. Although he knew a little bit about it, he was lucky enough to guess it.
Zhu Pingan knew very well that at this level, he could only give 10 points at most!
Lao Zhang beside him proudly threw down the test paper and comforted him casually.
"Okay, okay, stop looking. Come and correct the paper. I told you that this final question is too difficult and no one can do it!"
Several other physics teachers also waved their hands indifferently, picking up the test papers one by one and preparing to correct them.
Zhu Ping'an, who was disappointed, also picked up a stack of test papers and prepared to start correcting them.
Because for the sake of fairness, all the test papers were mixed and packed into five piles and stapled to old newspapers. He didn't know which class's test papers he had in his hands.
But looking at the test paper in front of him, Zhu Pingan hesitated for a while.
Still not giving up, I opened the test paper and started looking for it.
He didn't believe it. There were more than 300 students, and not a single student could do this question.
After turning over and over, Zhu Pingan's hand suddenly stopped.
There is another test paper, and the answer written on it is: 1/4ma!
Suddenly, Zhu Pingan's eyes lit up, but this time he did not rush to say anything, but carefully read the steps to solve the problem himself.
Don't look at the dense steps to solve the problem. If he guesses again later, he will be embarrassed.
But after looking at it for a while, Zhu Pingan sighed, holding the test paper and feeling completely discouraged.
The answer to this test paper is correct, but the steps are even more outrageous than the one just now, and have nothing to do with the steps to the correct answer.
Alas, it seems that my requirements are too high.
This kind of difficulty is indeed not something that a high school student can accomplish.
The frustrated Zhu Pingan corrected a few test papers without much interest and went home early.
After arriving home, after hesitating for a while, he picked up the landline at home and made a call to his former university physics teacher.
After telling the teacher this mechanics question word for word, Zhu Pingan complained about the teaching and research department and his students before hanging up the phone with satisfaction.
Teacher Zhu Pingan on the other side became interested after listening to Zhu Pingan's story.
He had just written out the general topic, and when he learned that Zhu Ping'an hadn't done it directly yet and had nothing to do, the teacher also tried to solve the problem.
Half an hour later, Zhu Ping'an's phone rang again.
Zhu Pingan, who was cooking, had already put this matter behind him.
However, the teacher looked very interested in telling him the answer, so Zhu Pingan could only listen honestly.
Zhu Ping'an was also curious. From the looks of it, the teacher was definitely interested in this question. Why did it take so long to complete it?
Just listening to his university teacher explain the steps to solve the problem bit by bit, Zhu Ping'an was suddenly stunned and blurted out.
"Teacher, that's not right!"
The teacher on the other end of the phone was stunned and read the answer several times in confusion.
"Yes, that's the answer. I've checked it..."
As he was talking, the teacher suddenly slapped his thigh.
"Oh, Ping An, you are right. It is indeed wrong. I used the college solution method to solve it. This is a high school question. I should use the high school mechanics method to solve it."
"Now that I've looked at it, I can figure it out. It just requires a few more troublesome steps."
It was just the teacher's chatter on the phone that Zhu Ping'an had no intention of listening to.
At this time, there is only one thought left, and that is the test paper I will read later today.
The steps to solve the problem above are exactly the same as what my teacher said!!!
"Teacher, can the problem-solving steps you just mentioned really solve this problem?"
Zhu Ping'an suddenly raised his voice and couldn't help shouting hastily.
This sudden sound startled Teacher Zhu Pingan.
Is this kid out of his mind?
Despite the scolding, the teacher nodded and explained.
"That's right, it can be solved by using the kinematics learned in college physics. I'm afraid you won't be able to use this topic when you teach it in high school. Ping An, Ping An, are you listening..."
It was just that the teacher shouted for a long time, but the protégé opposite still didn’t respond at all.
Just when he was about to curse his mother, Zhu Ping'an's somewhat lost voice sounded.
"Teacher, if I said that I saw a problem-solving process similar to yours in the papers I corrected today, would you believe it?"
"like me?"
The teacher was stunned.
"Wait a minute, you mean there are students in high school who can use college physics?
Quick, tell me the name Dududu..."
Listening to the busy tone on the phone, the teacher almost smashed the phone. This kid, after hanging up the phone, his wings became stiff, right?
Does he still know what Zhu Ping'an means? This is because he is afraid that he will abduct this physics genius and recruit him to the university!
On the other side, after hanging up the phone, Zhu Pingan was so excited that he almost jumped up.
He grabbed his wife next to him and kissed him deeply, then rushed out of the house happily, and his wife couldn't stop him.
Soon, Zhu Pingan returned to the science teacher's office.
Next to them, Lao Zhang and several other physics teachers had finished correcting their pile of test papers and were chatting there.
Seeing Zhu Pingan's arrival, he couldn't help but joked,
"Hey, Lao Zhu, why are you back again?
Have you found the student who can do that question?"
"Of course I found it!"
Zhu Pingan's answer surprised several people.
Then Zhu Ping'an directly picked up his pile of uncorrected test papers and quickly flipped through them.
Soon he took out a test paper and said, "Who said students can't do it? This student solved it and it's all correct..."
