What is light?

Is it a wave?

Is it a particle?

Or both.

Regardless of the truth, the wave-particle duality of light has long been written into high school physics textbooks.

90% of the students just remember this concept.

A small number of people went a little deeper and roughly understood the double-slit interference experiment.

After this short period of study, the concept of light returned to the exam paper and became a branch line in the question, hitting the mirror will reflect a symmetrical straight line, and by calculating the angle in between, you can get the due score.

But the solution to the dispute stopped here.

A wave is a wave, and a grain is a grain.

Duality?

What's the explanation? What is it?

As a teenager, he couldn't imagine why such a ridiculous description was written in a textbook.

It's as ridiculous as saying that "a person has a gender personality, she is a woman when she wears clothes, and he is a man when he wears no clothes."

Although Xie Qifen had such great doubts, he would not ask the teacher.

After all, since he mastered calculus, the science teacher couldn't answer any of his questions directly, and he could still say perfunctorily, "This has to be explained in calculus, and you can talk about it when you learn it." ”

So, the solution stopped here.

Maybe he didn't expect that this stop would be 27 years.

Originally, in those days when there was no internet, his only option was the university library, whether it was after school or on the weekend, he would take a long bus to the most prestigious university in his city, and then stand guard at the door, begging passing college students to take him in.

Naturally, college students also liked such a studious little brother very much, and would not only take him in, but also listen to his questions, either try to answer them, or personally lead him to the bookshelves of relevant textbooks and literature.

In these countless days and nights, a magnificent epic of physics slowly unfolded in front of the solution.

He realized that the wave-particle duality of light was not written down by someone with a pat on the head, but the result of a century-long debate.

According to the Granulators, light is a small particle that can be quantified and has mass, and Newton, Einstein, and Planck have undoubtedly proved this.

Wave School believes that light is an electromagnetic wave that interferes and diffracts, and Huygens, Maxwell, and Hertz have also proved this with no doubt.

It's like one group of people proves that someone is a man, and another group of people proves that someone is a woman.

This result is so absurd, but in fact, for a long time, such a completely contradictory two conclusions, at the same time correct.

It wasn't until the double-slit interferometry experiment, with the breakthrough of observation technology, that scientists decided to put a final stop on the debate by tracking every photon.

The principle of the experiment is very simple, find a board and open two vertical slits, then align the photon transmitter with the double slit and continue to emit it, and finally observe what kind of light spots will be left on the screen behind the board.

In the idea of the granularity, such photons are undoubted particles, and they either pass through the gap on the left or the right, and the probability is 50%, so that two clear vertical bars will be obtained in the end.

In Wavepai's vision, the light would undoubtedly interfere when it splits in two after passing through the double slit, so a series of beautiful zebra stripes will be reflected on the screen.

However, the end result was silence for everyone.

Observe it, it is a grain.

Don't observe it, it's a wave.

Be more specific.

As long as the photonic camera is placed, two bars will appear on the screen behind the double slit.

If you don't put it, you can stare at it with the naked eye, and the result is a beautiful zebra stripe.

It's like a person, she's a woman when you look at it directly, but once you pick up the camera, he's a man.

No matter how incomprehensible it is, it's a fact that has been proven time and time again.

No one expected that this experiment, which should have been the final word, would uncover a series of even more terrifying mysteries.

On this basis, Nils Bohr was born, setting off the beginning of quantum mechanics and proposing the three principles of the quantum world that are still unbreakable today.

The principle of superposition of states: In the quantum world, various possibilities coexist, and a person can really be both male and female.

The uncertainty principle: because the superposition state is not measurable, we never know what will happen to it next, and the devil knows whether it will be male or female in the next moment.

Observer's Principle: Although the man is both male and female, and the Schrödinger's cat is both dead and alive, we can never observe such a thing. Once observed, the gender of the person will be determined, either male or female, as for whether it is male or female, it is determined according to the probability distribution of the superposition state of the person at that time, which is essentially a random satisfaction probability, just like a mobile game gacha.

Einstein mocked this: God rolls the dice?

Pol's response was even more sarcastic: Don't command God!

The star-studded quantum strife begins.

If you have to pick out a few examples in this great scientific history, it is about Einstein and Bohr spraying all the way to death from the beginning of their meeting, and Schrödinger took advantage of the sage state between flirting with his sister to come out from time to time to stir up and abuse a cat.

Of course, in the teenager's reading of the disjointedness, he saw a series of great names and beautiful numbers -

Max Planck, Niels Bohr, Werner Heisenberg, Erwin Schrödinger, Enrico Fermi, Paul Dirac, Albert Einstein......

Planck's constant, de Broglie material waves, Schrödinger's equation, Heisenberg's inaccuracy......

Although he still can't understand the full meaning, it doesn't stop him from being obsessed.

If he didn't say it, he had never been in love, he had never been in love with anyone.

Quantum mechanics is his one, mysterious, eternal first love.

He followed in her footsteps, through high school, through competitions, to winning the world championship trophy and stepping into the country's most prestigious physics university.

But she never looked back at him.

Bell's inequality is her last sound, and the ghost imaging experiment is her last showy.

After that, there was a mess.

From philosophers to engineering liars, everyone has to go up and pinch her.

From the rich man to the promiscuous professor, everyone wants to cut a piece from her.

They dress her up and mythologize her.

They corrupted her and demonized her.

She gradually became glamorous and decadent, psychedelic and foul-smelling.

The teenager began to hate her.

He only wanted to remember her at the beginning.

Perhaps the person who should shout "smash the reality" the most should be him.

He thus rejects all quantum myths since the 90s.

At this time, the teenager has become a young man.

The young man returned alone to the point where he first met her.

Then he returned to his youth.

It's called "wave-particle duality of light."

He set aside reality and returned to the world of aesthetic abstract mathematics.

He wanted to find the bridge between them, the bridge between waves and grains, and he was convinced that this was the last key to her heart.

If "observations" can really change the results.

Then try to be like those great names.

Write it out in formulas.

Waves have formulas, grains have formulas, and "observation" must also have formulas.

Set together.

She will be back.

Since then, the young man has embarked on this path of destruction, which will never be restored.

In the conference room, Zhong Ping recounted the past calmly.

"The fame of resolving disputes in graduate school is very great, even greater than you and Guijianfeng combined, and the domestic academic circle must not be able to find a second one. ”

"I'm not saying that you are inferior to him, but under the material conditions of those years, it is a miracle that a local scholar like Xie Qifen can be published in top international journals and born and raised in an internationally recognized manner. ”

Therefore, no one dares to question what he wants to do, and both the college and the school cooperate with each other. ”

"In addition, at that time, qigong was crazy or something, and even the leaders really thought that he could study some great creation theory, and he was our Einstein. ”

"You know, in the pure theoretical study of mathematics and physics, computers, that is, computing power, are the most core resources. ”

"Let's just put it this way, half of the thistle's computing power at that time was his. ”

This phase lasted about three years until he graduated with a PhD. ”

"It's basically 0 results. ”

"Even negative results. ”

"Not to mention top journals, he has only published one article in third-rate journals, and he has been scolded so much. ”

"He is trying to reconstruct physics with the most basic mathematical methods, which should not be scolded, but he has not had decent results for a long time, but he always throws a bunch of mathematical content in his system to attack the cutting-edge quantum mechanics, which has caused a lot of notoriety. ”

"It's just using his own theory to deny others, which is a bit like the Minke. ”

"But the key is that he has the name of thistle, and he uses the resources of thistle. ”

"During this period, there were more and more returnees, including me, of course, Jinghua, who I went to first after returning to China, did not have a direct experience of the situation of the Jida Institute at that time, but I could always hear some of them. ”

"At least at that time, the returnee doctor was indeed stronger than the local doctor, and the strength was in the 'international information absorption', whether it was thought, knowledge or research methods, it was indeed more sophisticated, so people naturally could not understand the college's connivance at resolving disputes, which was as funny as practicing qigong for the whole people. ”

In addition, he is not very good at dealing with the world, and he always sprays whatever he thinks, or sprays with his own theory, which creates a situation where he is the enemy of the quantum world alone. ”

Later, with the change of leadership, the resources to solve the problem were naturally cut in half day by day, and in the end, even the students he brought with him ran away. ”

In fact, even so, his foundation and contributions are there, and it shouldn't be a problem to evaluate a professor. ”

But he is just hard-boned, obviously he has nothing, and he denies the progress of quantum mechanics since the 90s every day, and defines 90% of the people who are engaged in quantum mechanics in the school as misguided children and pyramid scheme scammers. ”

"As a result, almost 90% of the teachers in the school were vehemently opposed to the evaluation of the title several times. ”

"If he is a person who has no knowledge and doesn't let go of a fart, he should be rated for so many years, but he is like this......"

"After a long time, I simply skipped him and didn't comment. ”

"Today, these things have actually long passed, and now these teachers who are engaged in quantum have long since changed, let alone arguing with him, they don't care much about him at all. ”

"I meet occasionally, and I will tell him to apply and then evaluate. ”

He just shook his head and walked away. ”

"As for sending him to the experimental center, that's what I mean. ”

"The rating of ordinary students in his class is very poor, few people can understand, the exam basically relies on self-study, and there are a few times when he simply discloses the test paper before the exam, saying that it doesn't matter if he breaks the exam, isn't everyone here to mix diplomas, anyway, no one really wants to figure out the physics ......"

Based on this, letting him take another class will not end well for him or for the Academy. ”

"In his case, most people think that he is self-inflicted and deserves it. ”

"Personally, I partially agree with that, but I also understand him. ”

"He has a sufficient foundation in mathematics and physics, and his thinking is even more different from ordinary people, if there is really any theory that he must adhere to even if he dies, I believe that theory will have the value of persistence. ”

"Even I don't rule out you trying to understand his theory, it's just ......"

Zhong Ping solemnly stared at Li Zheng.

"You're approaching ...... in this form, with a team of this size. All of our teachers are worried. ”

"We don't have any doubts when a mediocre student comes into contact with him. ”

"It's just a few of you, and a few of you are the ones most likely to fall into it. ”

"Although I have limited understanding, I probably know that his theory is very beautiful and seductive, and it may be no less than the string theory in terms of form, and what is even more terrifying is that it is still a half-finished product, which has been cut in half...... It's hard for a student like you to restrain yourself from turning it into a finished product. ”

"But from what I know and what I do. ”

"It can never be a finished product. ”

"At least not in my lifetime. ”

"That's it, Li Zheng, we don't want to see a second one. ”

"I know these words sound nasty, but it's all for your good. ”

"If you insist on doing superconductivity theory research, I can give you the best professor of theory in our school of physics. ”

"That's my attitude. ”

Li Zheng was silent for a long time.

In this silence, I seem to see a more beautiful and more annoying solution.

Self-inflicted, obsessed, deserved, these descriptions are all correct, imagine the former fangs and claws, spraying on all sides to solve his disputes, he is even ugly.

But under that skin, that soul, which has no hesitation, is so beautiful.

"Never ......" Li Zheng shook his head a little choked, "Dean Zhong, these worries of yours have never been, Mr. Xie has never shaken off half a word of private goods with me from beginning to end, including the cellular automata and life games you asked about at that time, he didn't say anything." ”

Zhong Ping also groaned: "I can imagine how restrained he is, but if you study superconductivity together next, many things will not be able to get around." ”

"Hmm. Li Zheng held on to the table and got up slowly, "I understand the situation, I will go back and think carefully." ”

"Okay, I'm sorry for you. Zhong Ping got up and sighed, held Li Zheng's hand and said, "Please also understand our teachers in the Academy, it is our responsibility to say these words, in the end, no matter how you decide, we will definitely support it, even if we insist on resolving the dispute to carry out the project, I will definitely approve it." ”

"Thank you, Dean Zhong. ”

"Okay, don't make it so heavy. Zhong Ping smiled and pushed Li Zheng, "Let's eat, when you want to do high-energy physics, welcome to come to my class to audit." ”

"Definitely, I only recognize Mr. Zhong in high-energy physics!"

In the midst of this laughter, the atmosphere at the end was rarely eased.

Li Zheng walked down the stairs, in fact, he didn't have anything in his mind at this moment, but he still subconsciously walked to the door of the laboratory where he was located.

Just as he was about to push the door to see if Xie Qifeng had left, there was a voice from inside that seemed to be scolding and persuading.

"Solve the problem...... You can do it, don't harm people, you can't do it......"

"Remember that graduate student from the past? People are going crazy...... I don't read any books, go home and get your stuff......"

"Taking a step back, even if Li Zheng and the others really make a name for themselves, once your name appears on the paper, do you think there is any hope of publication?"

"This time, they are all the top talents in the school, how many years has the entire education system invested to raise so few, you just hold your theory, can you do it at home?"

Li Zheng wanted to kick in the door when he heard this, but he couldn't find a reason to interrupt.

It should be Professor Lu who said this, it seems that Zhong Ping has been talking to him for a long time, and he has been talking to Xie Qi here for a long time.

Just as Li Zheng made up his mind to go in, he heard a faint answer.

"No, it won't. ”

"This kind of subject, they can't do it with others, and only I can understand this set of quantum. ”

"It's their business what they do, but if they find me, I'll take it. ”

"Unless you fire me now and kill me. ”

"Let's go, I'm off work. ”

Immediately after, the voice of the former associate professor came from inside.

"Teacher Xie...... I know you're suffocated here...... Looking for a reason to get out. ”

"Is this good, I want to find a way, apply to the dean, and let you go to the Institute of Theory to do teaching and research. ”

"Neurotic, right?" said Xie Qifen incomprehensibly, "I said a long time ago that I would not talk about my theories in the teaching process, and a person who is engaged in physics has given up talking about the truth he believes in the most, what do you want me to do?"

"That's ...... ...... like this," Professor Lu's voice lowered, "You let go first, let Li Zheng go to my side to have a look, and you can also help me persuade him, if a few of them come to my side to do a project, we can put your name on it when an article is published in the future...... No matter what, it's not a problem to evaluate professors...... It's better than a bunch of you guys doing useless work......"

Immediately after, the sound of smashing things came from inside.

"Fart! shit!" Xie Qifen pushed the two away and walked briskly and scolded, "What are you guys doing with Li Zheng and them as fat sheep? Who fishes who's who? What the hell! The gang of people who sprayed me back then are much more backbone than you again." ”

"Solve the problem!" Professor Lu immediately scolded, "It's enough for your face, isn't it? You are a waste of eating in the courtyard and also deserves to teach Li Zheng???"

"That's it...... You don't go too far. The associate professor next to him couldn't help but say, "Sometimes you should also take a hard look at yourself, in addition to wasting money and misleading people's children, what else have you done?"

Then, the door opened suddenly, and Xie Qifen, who gave up refuting and brushed his sleeves away, bumped into Li Zheng, who was stupid.

Xie Qi's expression suddenly became embarrassed.

didn't look at Li Zheng either, he left with his head stuffy and touched the cigarette.

The two people inside were even more embarrassed when they saw Li Zheng.

Li Zheng looked at the two of them, and shook his head in disappointment, and then caught up with them.

Chased all the way to the old place, smoking corner.

Xie Qifeng didn't care about him, he just took one and put it in his mouth, and was about to collect the cigarette, but the cigarette case was snatched away by Li Zheng and smoked out.

"What do you learn blindly, give it to me. Xie Qifen raised his hand and grabbed it, "If it's okay, get out, it's annoying." ”

Li Zheng flashed over happily, fiddled with his cigarette and said, "This thing can really improve thinking efficiency?"

". I couldn't grab it, so I had to order it for myself, "If you can't do it, you can find someone else, I can't stand these people tossing me every day." ”

Li Zheng raised his eyebrows and smiled: "Oh, this is different from the attitude just now, doesn't it mean that only you can understand quantum mechanics?"

Xie Qifen's old face turned red, and he turned his head sideways and said, "Some said nothing?"

"Just to reassure you, we've all been under a lot of pressure today. Li Zheng stretched, looked at the cigarette in his hand, and finally stuffed it back into the box, "I'm not as weak-willed as you, and I need cigarettes for a short relief." ”

"Good luck, I hope you never use it. ”

"Okay, I'll ask you something. Li Zhengning asked Xie Qifen, "Don't talk angry, is it really as you said, no one knows quantum physics better than you?"

"This is the truth...... "If it's all over the world...... There should be two or three people who know better than me, one is a German ......"

"Okay, that's enough. Li Zheng patted his disagreement and said, "I'll go back and deal with it, and we'll start classes tomorrow." ”

"Hey...... You think about it......" Xie Qifen swallowed and foamed, "Although the old bastard surnamed Lu is farting, what he says is basically the truth, don't look for me if you want to get results, it's no problem if you want to study." ”

"Oh, when you learn, the results will naturally come uninvited. Li Zheng raised his eyebrows, rubbed his hands and said, "Come on, old prince of physics, I've been waiting for this moment for a long time...... Maybe you were taught to do it first, or maybe I learned to vomit first...... Who knows......"

At this moment, for the first time in learning, Xie Qifen felt a fear of being dominated.
