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

Liu Xusheng, who was still in doubt in his life, thought he was OK again.

Quantum physics was only gradually proposed at the beginning of the twentieth century. Compared with classical mechanics, optics and other disciplines, it is too young.

This means that many situations have not been perfected.

For example, the theorem is only used under certain circumstances, and beyond the situation, it has become a conjecture that people often say.

On this territory, there are many things that can be excavated.

But for ordinary people, the most intuitive feeling is two words: difficult to understand and difficult to learn.

Often listening, your face begins to heavy.

Involuntarily, a word popped up in my mind: what are you saying when you ride your horse.

Why do I feel like what you said is like God is throwing seeds, full of uncertainty.

Classic example: Schrodinger's cat.

Put the cat inside a box with a small amount of radium and cyanide in an airtight container.

The decay of radium has a probability. If the radium decays, it will trigger the mechanism to break the bottle containing cyanide, and the cat will die; if the radium does not decay, the cat will survive.

Traditional understanding: cats are either dead or alive.

But in the theory of quantum mechanics, it becomes something else. To put it simply: I don't know the state of the cat without opening the box.

So it is a cat that is both dead and alive.

do you understand?

I don't understand!

At the beginning, Liu Xusheng was confused by this class, and he explained to himself comprehensively for a long time before convincing himself.

Since then, he began to understand a sentence: the end of science is theology, and it is not without reason.

It is no wonder that many of the great figures in history, such as Newton, developed into the study of theology in their later years.

Look again, not far away, Xu Teng.

Sometimes frowning, sometimes writing quickly...

From the beginning to the present, Professor Chen has talked a lot, and he is almost catching up with their progress.

how?

Xu Teng, who has never met in the School of Physics, was able to digest so much and keep up with us when he first came to class?

Stop dreaming, God wouldn't dare to do this even if he throws a dick.

then...

Liu Xusheng was happy and cautiously looking forward to it.

Seeing how serious you are now, how embarrassed you will be after a while.

Deng Yi, who has been spying on the screen, is also a little worried about Xu Teng, because she has no temper at all because of quantum physics.

you torture me

A hundred times, I treat you like my first love.

The first few introductory courses almost gave her autism.

Although Xu Teng has a certain foundation, didn't he say that it is a hot weapon.

The knowledge of thermal weapons has nothing to do with quantum mechanics!

I think should not be...

When Chen Duowen started to teach Xu Teng, he arranged the general order of lectures.

Because Xu Teng doesn't have that much time, it is much more difficult to become an all-around researcher than a solo researcher.

Dean Yun also made the situation very clear.

Just as Xu Teng meant, first teach him all the basic courses at the fastest speed.

During this hour, Chen Duowen talked about a lot of basic content, and he even kept up with the progress of the students present.

"I should find a chance to ask Xiao Xu. Speaking alone will not necessarily deepen understanding. Asking it in the form of a question can deepen Xiao Xu's impression."

"Unfortunately, I can only be Xiao Xu's teacher for a while. Forget it, I will be satisfied for a while. When I meet those old friends in the future, I can say: I used to be Xiao Xu's teacher."

Chen Duowen knocked on the blackboard, this action made all the students in the class excited.

Because, this is Professor Chen's classic action before asking questions.

Deng Yi: What should I do? Xu Teng can't really answer.

Other students: Oh, here we go, the exam is coming.

Liu Xusheng: Professor Chen, please don't be soft-hearted, you must ask Xu Teng to the death.

"Xiao Xu, I taught you so much basic knowledge just now. I want to inspect you now, no problem."

When this sentence came out, everyone was stunned.

Professor Chen, why are you so humble?

Asking questions, do you still need to be affirmed by others?

"Of course, Professor Chen, it's my honor to take your course."

Although Senior Brother Yun made all the arrangements secretly, I have to say that Xu Teng really thought so.

Every old professor has come from that turbulent era.

Not only was there pressure from external enemies, but there were also people inside who were constantly doing things.

Can persevere wholeheartedly and dedicate one's strength to the development of the motherland.

Xu Teng also considers it an honor to be a temporary student of these professors.

Chen Duowen smiled even more happily, modest and courteous, with a clear goal, young and promising...

There is a successor!

Chao Wendao, evening death

OK.

It was this feeling.

"Okay, Xiao Xu, then listen carefully."

"Quantum mechanics, what is it about?"

When the question is asked, not only a sentence pops up in other people's minds: This is it?

Is Professor Chen pouring water? The sea outside is not as much water as you put in.

Xu Teng was also stunned for a moment, but still answered seriously: "Quantum mechanics is simply discontinuity and probability. In our classical physics, the states of all objects are deterministic, but in quantum mechanics the positions of particles and the Energy can't be measured..."

"Okay, it's alright."

Chen Duowen interrupted Xu Teng's idea of ​​continuing to speak, and what surprised him was that Xu Teng's memory was surprisingly good.

Because Xu Teng seems to have memorized all the words in the textbook...

He just said it once.

"Xiao Xu, then we will enter the next stage of investigation."

Turning around, Professor Chen began to write on the blackboard.

"In order for the hydrogen atom in the ground state to be excited to emit the Ryman system, the spectral line with the longest wavelength (a spectral line composed of the spectral lines emitted by the transition from the excited state to the ground state), at least the ground state hydrogen atom should be provided with how much energy?"

"The ionization energy of the ground state of the hydrogen atom is ___, and the ionization energy of an excited state atom with an ionization energy of +0.554ev has its electrons moving in the orbit of n2___."

......

Seeing the set of blackboard writing topics, everyone was dumbfounded.

I go...

I thought that Professor Chen was planning to let the entire Pacific Ocean be his water, but looking at it now...

Totally we think too much.

Professor Chen is still the same Professor Chen, and it is not because of Xu Teng that he has changed much.

Always be serious in the academic attitude.

It was the most basic question just now, but now it comes directly to the truth.

It's only been a little over an hour. During this time, Professor Chen basically just talked about a general basic content, and proposed theorems, formulas, and basic definitions.

So I wrote all the knowledge points just mentioned as topics...

Riding a horse is like teaching elementary school students about the mathematics they need to take in the college entrance examination.

Then I directly took out the Jiangsu mathematics real questions for the college entrance examination for you.

"Come on, you have done all these questions for me."

release water?

nonexistent!

This directly fills the challenge difficulty.
