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 the high school physics textbook.

90% of students just remember that they have such a concept.

A small number of people have gone deeper and roughly understood the double-slit interference experiment.

After this brief study, the concept of light returns to the test paper and becomes a branch line in a question. When hitting the mirror, a symmetrical line will be reflected. By calculating the angle between them, you can get the score you deserve.

But when they resolved the trouble, they stopped here.

Waves are waves, particles are particles.

Duality?

What is this explanation? What is this concept?

It was hard for him to imagine why such a ridiculous description was written in the textbook in a grand manner.

It is as ridiculous as saying that "a person has the same character as a man and a woman, she is a woman in clothes, and he is a man without clothes".

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

After all, since he mastered calculus, the science teacher has been unable to answer any of his questions in a positive way. He could have said perfunctorily before, "This must be explained with calculus, and I will talk about it when you learn it, ah."

So, the trouble of resolving the situation stopped here.

Maybe he himself didn't expect that this stop would last for 27 years.

At first, in that era without the Internet, his only choice was the university library. Whether after school or on weekends, he would take a long bus to the most prestigious university in his city, and then guard the door and beg passing college students to take him in.

Naturally, college students also like such a studious little brother. They will not only take him in, but also listen to his questions, either try to answer them, or lead him to the bookshelf of relevant textbooks and documents in person.

During these countless days and nights, a magnificent epic of physics slowly unfolds in front of the troubles.

He realized that the wave-particle duality of light was not written by anyone with a slap in his head, but the result of a century-long debate.

Lipai believes that small particles that can be quantified and have mass can be proved undoubtedly by small particles.

The Wat School believes that light is an electromagnetic wave that can interfere and diffraction, and Huygens, Maxwell and Hertz all prove this with certainty.

It’s like a group of people proving that someone is a man, and another group of people proving that someone is a woman.

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

Until the double-slit interference experiment, with the breakthrough in observation technology, scientists decided to make the final decision for this debate by tracking and observing each photon.

The experimental principle is very simple. Find a board to open two vertical slots, then aim the photon transmitter at the double slots, and continuously emit it. Finally, observe what kind of light spots will be left on the screen behind the board.

In the concept of the particle school, such photons are unquestionable particles. They either pass through the gap on the left or the one on the right, and the probability is 50%. In this way, two clear vertical bars will eventually be obtained.

In the vision of the Wattage, light splits into two after passing through the double slits, which will undoubtedly interfere, so a series of beautiful zebra stripes will inevitably be reflected on the screen.

However, the final result made everyone silent-

Observe it, it is a particle.

Without observing it, it is a wave.

More specific.

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

If you don’t sway, you can stare at it with your naked eyes, and the result is beautiful zebra lines.

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

No matter how difficult this is, this is the fact that it has been demonstrated repeatedly.

No one expected that this experiment, which should have been finalized, revealed a series of more terrifying mysteries.

On this basis, Niels Bohr emerged, setting off the beginning of quantum mechanics, and put forward the three principles of the quantum world that are still unbreakable to this day-

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

The principle of inaccurate measurement: Because the superposition state is unmeasurable, we will never know what will happen next. Do you know whether it is a man or a woman next moment.

Observer principle: Although this person 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 person's gender will be determined, either male or female. As for whether it is a male or female, it is determined based on the probability distribution of the superposition state of the person at that time. It is essentially a random chance that satisfies the probability, just like drawing a card in a mobile game.

Einstein mocked him for this: God rolled the dice?

Boer's response is even more sarcastic: Don't command God!

The star-studded quantum dispute began.

If you have to pick out a few typical examples in this great scientific history, it is probably that Einstein and Boer have been squirting all the way from the meeting to death. Schrödinger took advantage of the sage state of being a sage in the gap between flirting with girls and came out from time to time to mess up and abuse his cat.

Of course, in the boy's reconciliation, 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's matter wave, Schrödinger equation, Heisenberg's inaccurate measurement...

Although he still cannot understand the full meaning of it, it does not affect his infatuation.

If he had not said anything, he had never fallen in love with anyone.

Quantum mechanics is his only, mysterious, and permanent first love.

He followed her steps, walked through high school, competed, won the world championship trophy, and entered the country's most prestigious physics institution.

But she never looked back at him.

Bell's inequality is her last voice, and the ghost imaging experiment is her last gorgeousness.

After that, it was a mess.

From a philosophical genius to an engineering liar, everyone has to go up and pinch her.

From a rich man to a professor, everyone wants to cut a piece of her body.

They dressed her up and mythed her.

They corrupt her and devil her.

She gradually became charming and decadent, psychedelic and foul-stenched.

The boy began to hate her.

He only wants to remember her in the first place.

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

He therefore rejected all quantum myths since the 1990s.

The boy at this time has become a young man.

The young man returned alone to the origin of her first meeting.

Then he returned to the boy.

That place called "Wave-particle duality of light".

He put aside reality and returned to the beautiful world of abstract mathematics.

He wanted to find the bridge between them, the bridge between waves and particles, and he firmly believed that this was the last key in her heart.

If "observation" can really change the result.

Then try to be like those great names.

Write it out in formulas.

There are formulas for waves and particles, so there must be formulas for "observation".

Set together.

She will come back.

From then on, the young man embarked on this path of destruction that he would never be obsessed with.

In the conference room, Zhong Ping retelled this past lightly.

"When I was in graduate school, I had a great reputation, which was even greater than that of you and Gui Jianfeng. There must be no other one in the domestic academic circle."

"I'm not saying that you are not as good as him. It's just that under the material conditions of that year, it would be a miracle that can produce a scholar who is listed in the top international journals like ", and is born and raised and gained international recognition."

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

"In addition to the qigong heat and other things at that time, even the leaders really thought that he could develop any amazing creation theory, and that he was our Einstein."

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

"Just say that, half of the computing power of this big was his at that time."

"This stage lasted for about three years until he graduated from a Ph.D."

"Basically, there are 0 results."

"Even negative results."

"Not to mention top journals, he has only published one third-rate journal, and he has been scolded to death."
