[Boy, did you leave the venue early? 】
When Li Mu received the news from Director Wu, he was stunned.
Clam?
How did Director Wu know that he had left the venue early?
Then another message came from Wu Mengyuan.
[Do you know how many people behind you left because you left early and then followed you? Within a hundred minutes of the exam starting, more than a dozen people left the venue! 】
Seeing this news, Li Mu was stunned again, and finally couldn't help but sigh.
Sure enough, some people also left early.
And within 100 minutes of the exam starting, there were so many people.
Sure enough, Director Wu’s question was still too easy.
This time the gap can no longer be closed.
Fortunately, he wrote a little more carefully, and he must have gotten full marks, so the problem shouldn't be big.
Then he replied: [This is pretty good! It shows that under your leadership, Professor Wu, our physics department is full of talents and is thriving. More than a dozen people can finish all the questions in less than 100 minutes after the exam starts. It also shows that you are not too difficult for me, okay? Beat us all! # Thumb #Thumb #hold fist #hold fist]
We cannot directly point out that Professor Wu’s questions are too easy.
He still understands this truth.
As a result, Professor Wu did not reply for a long time, until finally he sent him a voice message that lasted for sixty seconds.
Huh……
Why did Professor Wu send such a long voice message?
Sixty seconds seems to be the maximum limit, right?
Since he was in the library, he put on headphones and listened to the voice.
"You really want to piss this old guy off to death, right?"
"Except for you, the dozen or so people basically turned in blank papers, but you were a good leader. I was going to write down the names of all of you who submitted your papers in advance, but I didn't expect that you would be the first one to turn in your papers. .”
"There are so many talented people out there, do you just think my questions are easy?"
"Do you want me to open a separate examination room for you in the future? Let you take the examination by yourself?"
"besides……"
"...Next time I will..."
For sixty seconds, Wu Mengyuan went on and on, and it came to an abrupt end before he even finished speaking.
Obviously, sixty seconds is not Professor Wu’s limit, but WeChat’s limit.
After sending this voice message, Professor Wu sent a message.
[You come to my office now. 】
What else can Li Mu say about this?
Naturally, I can only respond quickly: [Okay professor! 】
He touched his face. Did he misunderstand his feelings?
Except for him, the next dozen candidates who submitted their papers in advance basically turned in blank papers?
Is it so difficult...
After thinking for a while, he finally shook his head.
He thought about the reasons why others couldn't do it for a long time in his mind, and then reviewed the difficulties of those questions, and he found...
Have it?
Forget it, let’s not worry about it. If Professor Wu comes to find him, he has to go there.
It seems that I accidentally slapped the horse's leg when I flattered him just now. I have to smooth over Professor Wu's temper later.
So he temporarily stopped what he was doing, then left the library and went to Professor Wu's office.
…
Soon, Li Mu arrived.
When he entered the office, he saw Professor Wu looking at him with an annoyed expression.
"You're the only one who thinks the questions I asked are easy, right?"
Straight to the point, Wu Mengyuan expressed the source of his anger.
Just kidding, he is famous for his difficult questions, but now he is looked down upon by this young man?
"Ah...no, no!" Li Mu waved his hands repeatedly, "I never said that!"
"Do you think I didn't notice your hint?"
Wu Mengyuan waved his hand and said: "The teacher is very happy that you can get full marks, but the teacher is not happy because the questions are easy."
Immediately, he took a piece of paper from the side and put it in front of Li Mu, "Here, you can do this question."
"ah……"
Li Mu was stunned, question?
Finally he realized that Professor Wu was planning to get back together with him!
cough!
Then I think this question should be a little interesting.
"Good professor."
So he took the paper and looked at the question.
[Consider a particle moving in a one-dimensional potential well. The particle mass is m, and the expression of its potential energy V(x) is V(x)=... In any such quantum state, the particle can be described as having a standing wave. In the form of de Broglie waves, the boundaries of the potential well are wave nodes. 】
[1. Determine the lowest energy value that the quantum particle in the potential well can take; 2. Write the expression of En; 3. Write the wavelength of the photon emitted when the particle transitions from the first excited state (E2) to the ground state (E1) Expression of λ21. 】
Seeing this question, Li Mu was stunned for a moment.
This is...the stuff of quantum mechanics.
He raised his head and glanced at Wu Mengyuan.
Wu Mengyuan stared back, "Look what I'm doing, write your question."
Li Mu immediately withdrew his gaze and continued to read the question in his hand.
He took a guess, and it seemed that Professor Wu was really trying to regain his position. He actually started studying quantum mechanics in his junior year.
Of course, among the three questions in their competition, the third question was about quantum mechanics, and in the subsequent International College Student Physics Competition, quantum mechanics was also included in the examination syllabus.
But for him, he has already finished studying quantum mechanics in undergraduate physics, and has already expanded deeply and extensively. He can still do such quantum mechanics problems.
Thinking about it, this question must be very difficult.
Thinking of this, he began to analyze this question.
Well……
Um……
ah?
After spending a minute analyzing, Li Mu didn't know how to express himself.
hiss……
It seems...it's not particularly difficult?
It's a little more difficult than the third question in the exam just now, but it's not very difficult either.
this……
He secretly looked up at Professor Wu again.
After realizing that Professor Wu was still looking at him, he quickly withdrew his gaze.
It seems that I can only act once.
As soon as I thought about it, my acting skills came into play immediately.
Some frowning and thinking hard, some scratching their heads and looking confused...
At this moment, he seemed to be possessed by an actor, making this question look like a world-class problem.
Professor Wu on the side looked at Li Mu with an expressionless expression.
Just now, Li Mu secretly glanced at him for a second time, and then immediately put on a difficult expression. He immediately saw through this kid's acting skills.
Ha, young man.
I've seen more dramas than you eat salt.
Still pretending.
He started to ask this question to Li Mu, and he felt a little embarrassed, because he knew how difficult this question was, and he had a relatively high level of knowledge. Li Mu was only a freshman. If he didn't have enough knowledge, At that point, it is definitely not enough.
But now...
He didn't feel embarrassed at all.
It seems that my question is still easy.
only……
Are there really exam questions under this kind of exam-oriented education that can be difficult for this kid?
Such questions couldn't help but arise in his mind.
