Soap bubbles are formed by the water film between the hydrophilic group and the hydrophobic group in the solution. The key to the formation is the surface tension of the water. It has nothing to do with hertz? !

The distance between atoms and molecules inside soap bubbles is simply nonsense. Molecules are made up of atoms. For example, a water molecule is 2 hydrogen atoms and [-] oxygen atom.

Reduced distance?How to shrink?High frequency vibration when breaking?Can it still produce light particles?Which light particle?Also weak nuclear reaction?

What a load of nonsense!

The bursting of soap bubbles is indeed accompanied by some energy release, but it is not a high temperature of tens of thousands of degrees, there is no such thing at all!

It is an implosion that occurs when the air bubbles in water burst, and this implosion is accompanied by the release of energy such as flashes and high temperatures!

"So, everyone, what's the point of discussing these things?"

"Or, do you want to find elements that are popular recently and add them to the real test questions for the postgraduate entrance examination?"

What Xu Heng said made all the professors look forward to it.

Fang Zhonggui, "Student Xu Heng, do you have any direction?"

Xu Heng thought for a while, and said casually, "I came across a short video when I came here, and I think it can be used for the physics entrance examination questions."

Teachers, "???"

Fang Zhonggui, "This...!"

He suddenly regretted it.

When I came here, I randomly swiped a short video...

Can it be taken out directly?

This is the Peking University Physics PubMed!

Xu Heng, are you serious?

You are more rigorous wow!

Hey Hey hey……

Amid everyone's doubts, Xu Heng said, "This is a story like this. One day a, b, c and d met to play badminton together."

"During the process of playing badminton, a's shuttlecock accidentally fell into the air vent in the basement, so d offered to help a go down to pick it up, b also offered to go down with them, and then c waited for them on the top and watched With the racket."

"When I just went down to the first floor, d told a and b that his key had been lost and he wanted to go back to find the key. At this time, a and b did not wait for d in place, but chose to continue walking to the basement. When they walked to the middle of the corridor, they felt that the surrounding area was very empty, and they happened to see a light in front of them, so they ran towards the light together."

"After the two ran out, they found that the place where they came out was near the back door of the school. They saw that the elementary school across the street had finished school at noon, so several of them went back directly through the back door."

"Back in class, I saw C who was looking at the racket. C said that he had waited for a long time but didn't see the two of them coming out, so he came back first with the racket."

"At this time, a saw that there was no d's racket in c's place, so he asked cd's racket, c replied who is d, I don't know this person. So when the class is over, b came to a and told him that d disappeared , all the people around me don't remember d."

"A also felt very strange, so he went to D's class to ask about D's situation, but everyone, including the teacher, said that there was no such person, including the photos taken together before, sign-in records, etc. There were no records, and D seemed to have never existed existed."

"This incident caused quite a stir on the Internet before."

But even so... the professors and teachers are also frowning.

"Student Xu Heng... you, what do you want to express...?"

"???"

Even Fang Zhonggui couldn't help frowning, and stared at Xu Heng suspiciously.

Xu Heng said bluntly, "Here I will mention an interesting pseudo-human algorithm."

The professors and teachers, "???"

Xu Heng, "There is a setting here that there are only a few real people left in the world, and the others are computer-controlled simulations. Like many games, when a person enters a place, the place is activated, and when the person leaves Afterwards, the area fell silent again."

The more professors and teachers listened, the more puzzled they became.

Is this a physics study?

What is this ghost?

If the person invited today is not Xu Heng, or some other professor or teacher, everyone will definitely think this person is crazy!

If not crazy!

Who would utter such nonsense? !

Fang Zhonggui was speechless. He really wanted to ask Xu Heng what he was going to say, or rather, Xu Heng was just talking nonsense here, not for the sake of asking questions.

But he still held back!

Xu Heng is always able to catch people by surprise, so he has to be patient.

But some professors were already pale and ready to fight back to refute Xu Heng.

But Xu Heng still didn't stop, and continued, "This is similar to the fact that the moon might not exist when I don't look at it..."

"This thing is also like the conscious behavior of our creatures, just like many people are NPCs. The world is so big, and the scope of our activities is extremely small. People will never find themselves in this environment, and everything seems reasonable and normal."

"but……"

Xu Heng was talking, and finally a professor interrupted Xu Heng's words.

"Xu Heng! Please wait a moment, please... I don't mean to disrespect others, and I don't mean to disrespect you. I just follow first. Do you respect us?"

Look at what this said, respect is on the lips?

Xu Heng sneered, said nothing, and wrote a question directly on the blackboard:

A two-level system is shown on the right, illuminated by light with a circular frequency of wo, causing stimulated transitions.

体系的波函数为a1e(-iw1t次方)|1+a2e(-iw1t次方)|2,相互作用的哈密顿量为H=-μ*Eo(e(iw1t次方)+e(-iw1t次方))

(1)用含时间薛定谔方程求t时刻粒子处于|2态的几率,证明|a2(t)|2=sin2Vt,V=(μ12*Eo)/2h,初条件为t=0时,粒子处于|1态。(注:忽略e(i2wot次方)项,又μ12=μ21)

(2) Qualitatively analyze the physical meaning of this result.

After writing the question, Xu Heng looked at the professor, "Professor, what do you think of my question?"

The professor was dumbfounded on the spot, how could he have expected Xu Heng to come up with such a question for him in minutes!

Very satisfactory!

At the same time... it is also very difficult!

And the angle of the question is very tricky!

The topic is difficult!

It is even more difficult to ask to use the "Schrödinger equation" to solve it!

The professor froze on the spot.

He was completely dumbfounded.

For Xu Heng, he gave due respect, because he had heard about Xu Heng for a long time!

But today, in his opinion, Xu Heng is nothing more than mediocre, and he has even been leading everyone to talk nonsense, so impatient, he can't stand it anymore.

He wanted to interrupt all this!

I really want to tear up the "flattery" of these people!

That's right!

In his eyes, people like Fang Zhonggui are "flattering" Xu Heng.

He didn't think Xu Heng had much talent!

At least that's what he thought at the moment before!

He thinks that Xu Heng is a model of being overly sought after!

But that's all!

Can--

Xu Heng saw through all of this, and without saying anything, he just gave a random question.

Get off the horse!

Immediate results!

The professor was speechless on the spot, and his intestines were full of regret.

People who can ask such questions!

Between him and him, it's up to you!

Everyone present had the answer in their hearts.

Xu Heng turned around, returned to Fang Zhonggui and the others, and said, "Let's continue."

"However, as long as it has an algorithm and is a system model, there must be bugs. Many people present should have suspected something or someone's abnormal existence."

"For example, the incident of classmate D I mentioned above, in fact, this is very likely to involve the hippocampus effect."

"..."

"It is widely believed that matter determines consciousness, but..."

"I don't know if you know, the most famous experiment about quantum mechanics is the double-slit interference experiment."

Everyone nodded.

Xu Heng continued, "I won't repeat the process one by one. The conclusion is that the double-slit experiment shows that in the process of light propagation, if you don't look at it, it propagates in the form of waves. This is what is commonly said Light waves, and when you look at it, it becomes a particle, which is what we often call a photon."

"So, in some ways, it's consciousness that determines matter."

When Xu Heng said this, some professors finally began to gradually understand what Xu Heng meant.

He wanted to use the incident of classmate d to draw out the extensive knowledge of physics involved in the next step, but...

"Student Xu Heng, it seems that we have surpassed the standard! If we continue to chat, the knowledge involved will be wider and deeper! We can't go on any longer!"

"Even the hippocampal effect and the double-slit interference experiment came out!"

"This, this..."

At the same time, all the professors stared at Xu Heng.

……

Kneel for all support!Thank you! .

Chapter 338

"So, from the very beginning, student Xu Heng, you are not interested in drinking?! You want to use the current hottest events and the most attractive points of attention to come up with questions!"

Many professors have come to their senses.

As for the professor who denied Xu Heng, his intestines were full of regrets.

For the first time in the past few decades, he has deeply realized from himself what it means to shoot the first bird!

"Hey……!"

He sighed resentfully, momentarily at a loss.

Mention the double-slit interference test.

Many professors and teachers were extremely excited.

Double-slit interference test.

As one of the top ten classic physics experiments in the world, the double slit experiment has caused many physicists and scientists a headache.

The double-slit experiment is an optical experiment, but many people say that the double-slit experiment is actually scary, and it makes people doubt everything they see in the world.

There is a terrifying side to this experiment, and it even affects the falsehood of the world.

It has always been controversial.

Faced with such a controversial experiment, these physics professors naturally would not miss the opportunity to discuss.

Especially when Xu Heng is present!

They all wanted to hear Xu Heng's opinion.
