Black Technology: Starting From The Completion Of The Design Of The Lightsaber

Everyone looked at Xu Teng, waiting for his next move.

Someone started talking in a low voice.

"Fuck... Professor Chen, this is true!"

"One thing to say, this behavior directly opened my eyes."

"At first, I thought that Xu Teng's senior brother had a lot of face, but now it seems that Professor Chen's set of topics is not giving Xu Teng a chance!"

Some classmates began to turn their heads to look at Liu Xusheng.

Because the one who knows Professor Chen the most is Liu Xusheng among this group of students.

"Liu...Brother Liu, are you saying that Professor Chen is giving Xu Teng a slap in the face?"

Originally, this person was going to call him by name, but after thinking about it, he couldn't be so real.

We will meet every day from now on.

It was this subtle difference that Liu Xusheng noticed.

Good guy, this Professor Chen hasn't said anything yet, I almost changed from Brother Liu to Xiao Liu.

Liu Xusheng frowned, if Professor Chen didn't respect Xu Teng so much at first, he would really think it was an act of making things difficult for him.

but...

Even asking a question has to tell Xu Teng first, is this still making things difficult?

That is of course impossible.

So, this is the right thing to do.

That's right, it's important.

Unlike other professors, Professor Chen has a rigorous attitude towards academics all his life.

In the bottom of my heart, I also hope that Longguo scientific research will have successors.

then...

The more he cared about the person, the more he would carefully examine the younger generation.

To put it simply: it will not put a drop of water.

so...

Xu Teng is probably the person that Professor Chen values ​​most in his life.

How can anyone finish the basics of quantum mechanics in just over an hour, and immediately start the practice test.

Is this a test?

This is simply killing.

Liu Xusheng thought about it in a different position. If it was himself, after more than an hour, let alone do the problem.

I'm afraid I don't even understand the meaning of some of the questions.

Rolling his eyes, it is directly: who am I, where am I, and what am I doing.

Abba Abba.

As soon as he thought of this, Liu Xusheng began to be incompetent and furious: "What do you care about Mawei, not Mawei. It's better to watch it quietly by yourself."

"I..."

The student who asked the question originally wanted to say: "Liu, don't give you some sunshine, you will start to shine..."

However, in the end, he was forced to hold back.

At this moment, Deng Yi, who was sitting next to Xu Teng, became nervous: "You...you really have to go up and do it.

question? "

The other students also turned their heads to look at Xu Teng.

Because that's exactly what they thought.

Are you really going up?

People, at least, shouldn't be so defiant.

Xu Teng wouldn't dare to go up if he didn't drink the Red Star Energy Liquid.

But after drinking this energy liquid, many feelings are really indescribable.

The fundamental theorem of quantum mechanics was indeed memorized after he heard Professor Chen say it once.

In the eyes of everyone, it is completely impossible to digest the basic knowledge taught by Professor Chen for more than an hour.

But that hour or so was stretched out in Xu Teng's mind.

Just like an archived file, it is constantly slowed down and read.

Complete digestion until now.

impossible?

Sorry, I think it's more than enough.

So, Xu Teng smiled at Deng Yi: "It doesn't matter, I just want to challenge myself."

Challenge yourself?

Professor Chen smiled and said in his heart, "Yes, young people just want to try unknown difficulties."

At this time, the news in the WeChat group was already very lively.

[I love Big Watermelon]: How about it, Xu Teng couldn't answer a question, so he asked him to pretend.

【天大地大】: Hard to say, after all, if you enroll through special channels, there is still something to be learned.

[God has arranged the greatest]: I don't think so. Professor Chen is famous for his rigorous scholarship. I know a senior who was scolded and cried by Professor Chen before. If Professor Chen really asked a question, he would never let the water go.

【I love big watermelon】: So Xu Teng can't protect himself today, hahaha!

[Look at me drifting]: You can't target Xu Teng just because he is handsome. A group of dog men.

Um?

I love the big watermelon, frowning and saying in my heart.

Where did this stupid woman come from, why is her speech so ugly, kick it out.

[Failed to kick out. 】

Click on the attribute of [Look at me drifting] to take a look.

Gan!

It turned out to be the group leader.

Nima's... There are bad people in the crowd.

At this time, someone posted the latest news in the group.

[Scientific research is so tiring]: Just now, Professor Chen asked Xu Teng about the definition of quantum physics on the spot. If Professor Chen hadn't stopped him, Xu Teng would have memorized all the definitions in the textbook.

[Scientific research is so tiring]: In the latest news, Professor Chen gave a blackboard on the basics of quantum physics. Although there are some basic topics that I can't understand, Xu Teng

Doing questions on stage.

It was followed by a candid photo.

Xu Teng listed the equation next to him with chalk and was solving it.

[Scientific research is so tiring]: By the way, I want to explain this photo. It seems that the speed is not fast, but in fact... Xu Teng's speed of answering questions has already started to take off... It's just ridiculous to open the door to the ridiculous, and to get home.

With this series of latest news, the group fell into silence.

No, not possible.

How can there be such a person in the world.

Someone who has never appeared in the School of Physics, just listened to the class for more than an hour today, and began to perform a basic answer on the spot.

And it's still a question from Professor Chen, who never releases water.

......

When Xu Teng got the chalk and walked to the first question, he found out: the first question is indeed a basic question.

The main point of solving the first problem is that it is calculated according to the experimental law of hydrogen atom spectrum.

It can be obtained from the Lyman formula and the Rydberg constant, and n should be 2 or 3.

The spectral line with the longest wavelength, corresponding to n=2

At least the energy hv (lower case above) that should be provided to the ground state hydrogen atom = e2, and because...

So, the result is...(13.6ev2)=10.2ev

The surrounding classmates were dumbfounded when they looked at the familiar formulas.

It's not that they can't figure it out, it's that this person listened to the lecture for more than an hour.

Some people do not believe in evil, they take out the scratch paper and do it.

The sound of clattering sounded, and after a calculation, the result was indeed 10.2ev.

boom...

Everyone heard a heartbroken voice in the bottom of their hearts, and their mentality exploded on the spot.

Liu Xusheng secretly said: "Nima's...why did you perform a miracle for us on the spot?"

The point is not here...

The second question, Xu Teng started to skip steps, yes, skip steps.

Problem Solving Point: Ionization energy refers to the energy required to excite an electron from the ground state to the free state.

The ground state ionization energy of a hydrogen atom...

Writing here, Xu Teng did not write.

I drew with chalk next to it, so I filled in the blank space of the title:

The ionization energy is 13*6, and it moves on the orbit of n=5.

There was another screeching sound.

The final result...

Completely correct.

Everyone's mentality exploded.

You are riding a horse, why you can start jumping steps from the second question, you can count it right.

And let us not live.
