Global Wanted: Start Five-Star Prison Break

Page 413

The original professional teacher had already been on leave due to illness, and everyone thought that this semester's class could only be made up next semester.

But no one expected that the school would recruit such a powerful professor.

This surprised everyone.

But now, Su Yu looked at these dozens of students and nodded with a smile.

"Who is the study committee member?"

"Professor, me."

A very cute girl raised her hand and looked at Su Yu excitedly.

Regarding this, Su Yu nodded again and asked.

"Where have you been in previous classes?"

"Professor, we have covered the double-slit interference delay experiment before, but we haven't talked about it yet." The girl replied quickly after thinking about it.

In this regard, Su Yu nodded and motioned for the girl to sit down.

"Since I haven't talked about the double-slit interference delay experiment, I just have time tonight, so I can give you a preliminary introduction to the general process and theory of this experiment."

Chapter 0369 of scientific supernatural, strange results

Let me tell you about the initial process.

As soon as Su Yu said this, the whole classroom was immediately quiet.

To this, Su Yu smiled lightly.

"This experiment involves a lot of things, and the background is quite complicated. Here I will try to help you understand this experiment in an easy-to-understand way."

As he spoke, Su Yu wrote a line on the blackboard.

[This is the first supernatural event in the history of science]

Su Yu wrote this sentence, which made many students' expressions suddenly startled.

without him...

It is unbelievable that the words science and supernatural are linked together.

This is simply incompatible!

As for this, Su Yu was not in a hurry to explain anything, but looked at everyone.

"As I wrote on the blackboard, the double-slit delayed interference experiment is the first supernatural event in the history of science."

"What I'm going to say next, I hope that all students will look at it from a rational, objective and inclusive perspective, although the result may not make you objective."

Su Yu smiled lightly and quickly got to the point.

"Just as people 1000 years ago couldn't understand today's technology, people 100 years ago couldn't understand quantum physics either."

"First ask everyone a question, is light a wave or a particle?"

Su Yu smiled and looked at the hundreds of people in the classroom.

Hearing this, someone immediately raised their hands.

"Professor Lin, light is wave-particle duality!"

"Very good, quick response."

Su Yu nodded with a smile.

"Yes, light has wave-particle duality, this is what we have drawn from the conclusions of our predecessors, but do you know that there was a grand war in the scientific community on the issue of whether light is a wave or a particle? "

"Now, let's go back in time to the early 20th century."

Su Yu wrote a year on the blackboard.

"In 1924, Debro proposed the wave-particle duality. Before that, the entire physics community had waged a protracted war over whether light was a wave or a particle."

"Among the scientists who participated in the war, there were many scientific giants including Newton and Hooke, but in the end it turned out that they were all wrong."

"Light is neither just a wave nor a particle, but has wave-particle duality. The reason why we can draw this conclusion is because of the double-slit interference experiment, which is the focus of our lesson."

"That's the point of the battle over whether light is a wave or a particle."

"It doesn't matter whether the result of the double-slit interference experiment is a wave or a particle. What's more important is that it leads to a new theory. Here we will talk about it later. First, let's talk about the experiment itself."

"In order to prove whether light is a wave or a particle, Popie and Granitie decided to do an experiment. The experiment itself is very simple. It is to let light pass through a partition with two slits."

"Lipai believes that light is composed of individual photons. When you turn on the flashlight, the light will burst out continuously from the flashlight, forming a beam of light."

"While Pai believes that light is a kind of wave, it will take itself as the origin and radiate and spread around, similar to the ripples on the water surface."

"It is worth noting that both the Lipai and the Wavepai had sufficient theoretical support at the time, and this is also the reason for the dispute between the two parties."

"And now going back to the experiment itself, the experiment is to let the light pass through the slit, and finally fall on the photosensitive plate behind the slit."

"If light is a particle, then after it passes through the gap, it will clearly leave two bars behind."

"And if light is a wave, it will leave behind continuous stripes similar to zebra crossings due to interference effects."

"That's the idea of the experiment at the beginning and the possible outcomes."

"OK, the first experiment has started, the results obtained are very clear, the light shows a zebra pattern behind, Poppai wins!"

"This result made Popai very excited, but Lipai felt dissatisfied, because in Lipai's theory, just particles should be emitted one by one. You are obviously cheating like this!"

"So at the request of Lipie, the second experiment started, and this time the photons were emitted one by one."

"And the result is exactly the same as before, showing zebra patterns, and Popai wins again!"

"This conclusion makes the whole particle group feel unbelievable, because according to the wave theory, the appearance of zebra patterns is due to the interference of light, but after a single photon is emitted, it can only pass through a single gap. How can zebra patterns be formed?"

"Could it be possible that the photon was split into two during the process of passing through the gap? This is impossible!"

"So in this case, the third experiment appeared, and this time is also the weirdest one."

As Su Yu spoke, he wrote a few words on the blackboard.

【Observer Principle】

"Now go back to the third experiment. In the third experiment, Lipi installed a sensing device on the photosensitive plate. It can sense which gap the photon appeared from, and the experiment begins."

"In this experiment, at the beginning, all the granules were relieved. Yes, the photon did not split, but the same major problem appeared."

"The same experiment, but with additional sensing equipment, this time the structure changed from zebra pattern to two bars, and the two bars represent light particles!"

"This conclusion caused an uproar among all the popies. How is this possible? Similarly, the grain pies are also unbelievable. Why did the light suddenly change from waves to particles under the same experiment, just with the addition of sensing equipment?"

"What's the situation? Everyone may not understand the meaning behind it. Just particles and waves are backed by a group of scientists, and these are all based on sufficient theory."

"And now, these theories are about to collapse. Why does light convert from waves to particles when it is observed?"

"What does this represent? When you don't look at it, it is a wave. When you look at it, it becomes a particle again."

"It's like I'm giving a lecture to my classmates now. It can be objectively considered that I will definitely give a lecture today. Even if I don't give a lecture, it is because of some personal reasons. But if you look at the results of the double-slit delay interference experiment , Whether I will come or not depends on whether you are observing. In other words, whether you are sitting here."

"Furthermore, in our world, if the individual is not in the state of observation, does the world exist?

Will your relatives, your friends, be particles when you observe them, but turn into waves when you leave? "

Su Yu said with a smile.

When he said this, everyone present was in an uproar.

What kind of theory is this?

Is there a state when observing, and another state when not observing?

In the live broadcast room, countless viewers were also in an uproar.

【No, wait for me to sort out my thoughts, I don’t quite understand it】

【I seem to understand. God Su’s analogy is that this world, when we see it, is in one state, and when we don’t see it, it’s in another state? 】

[This is the truth, this is the weirdest part of the double-slit delay interference experiment. Since light can be observed and not observed, it shows two different states, so is our world also the same? 】

[The state when you go out and meet a person is completely different from the state when that person disappears from your sight! 】

[I am stupid!For some reason, I feel a little scalp tingling, thinking of the game, sometimes the action speed is too fast, and the screen and NPC are not loaded in time...]

[absolutely!Absolutely! 】

[Earth OL is really hammering! 】

In the live broadcast room, there were also countless audiences discussing.

At the scene, Su Yu still had a faint smile on his face.

"The current state of the students is the state of the scientists at that time. They were shocked and unbelievable, so they followed up with the fourth experiment."

"The method of the fourth experiment has been improved compared to the third experiment. Specifically, when the photons are emitted and pass through the gap, they are about to fall on the photosensitive plate, and the sensing device is quickly added."

"And the result is also undoubtedly the same as the previous third time. No matter how fast the induction equipment is installed, as long as the observation state is in, the light will always be in the particle nature, and as long as the observation state is released, the light will show the wave nature again."

"It's the same, not only that, even if scientists of later generations use quantum entanglement technology to emit photons, the results they get are still exactly the same."

"That is, photons exhibit particle nature when observed, and wave nature when unobserved."

When Su Yu said this, everyone was even more surprised.

One of the female classmates raised her hand weakly.

"Teacher, since what you said is so scary, how is this experiment finally explained?"

"How to explain?" Su Yu smiled, "Good question."

As he spoke, he wrote a name on the blackboard.

【Bohr】

"This weird changing state of light caused countless scientists to be puzzled and even panicked until Bohr's birth."

"He proposed the principle of superposition of states, the principle of non-measurement, and the principle of the observer."

"This superposition of states means that there are various possibilities for everything in the quantum world. It may be on the left, it may be on the right, or it may be both left and right. These are beyond our imagination. After all There is no black and white in the real world.”

"The second cannot be measured, which means that the superposition state can never be measured accurately. We can know its position, but it is impossible to know its speed. It is worth noting that the impossibility here is not due to the inadequacy of current technological means It is possible, but it is impossible from the law of the universe, just like never reaching the speed of light."

"And the third one is the observer's principle. Although things in a superposition state are in various possibilities, it is impossible for us to see things that are both black and white. Therefore, as long as we observe, we will get a definite As a result, things in a superposition state are collapsed into a definite state at the moment they are observed."

"As for how it collapsed, it has not been explained yet."

"And these are the explanations given by Bohr. Of course, most scientists don't agree, but they can't refute this explanation, because they don't know what the principle is."

"Just for this, a cat appeared, Schrödinger's cat."

As he spoke, Su Yu was about to write a few words on the blackboard.

The bell rang.

Chapter 0370 get out of class is over, the cigar is really exciting

The bell rang.

Ok?

Seems like it's time?

Su Yu looked at everyone.

Everyone obviously didn't realize how quickly time passed.

"get out of class is over, since that's the case, let's talk to you next time when you have time."

Su Yu spread his hands, with a helpless expression.

This made many students look a little regretful.
