Into Unscientific

【Overthrow the foundation of the physics building】.

Hearing the words Xu Yun said.

Lao Fa was taken aback for a moment.

Immediately, he thought of something, and quickly glanced at the bustling melon-eating parties around him.

Then he dragged Xu Yun aside, lowered his voice and said to him:

"Student Luo Feng, what you said about 'overturning the foundation of the physics building' is an exaggerated rhetorical technique, or..."

"Will it completely overthrow our existing physical system?"

finished.

He stared at Xu Yun steadfastly, waiting for the young man's reply.

If in half a day... no, if someone had said such words to him in front of Old Fa two hours ago, he would never have believed even a single punctuation mark.

What are you kidding?

Modern physics has gradually established its foundation since the 15th century, and it has been more than 400 years so far.

Thanks to the efforts of Kepler, Mavericks, Franklin, and Ampere, today's physics is already a very mature subject.

These leading physicists like Faraday also intend to jointly write a letter recently, suggesting that the Royal Society separate physics from the subordination of chemistry and establish it as an independent discipline.

under such circumstances.

Some people brazenly say that they can overturn the physics building, I am afraid that everyone will find it absurd and ridiculous.

But now.

Whether it is the result of the speed of light calculated in the first experiment, or the photovoltaic phenomenon that is still bubbling, it has proved one thing:

What Xu Yun said was probably the truth.

After all, there is a fat fish behind him endorsing the book.

Therefore, as the current leader in physics, Lao Fa has to consider certain extreme situations:

If, if, in case Xu Yun really made a super, super, huge, huge news, completely negating the existing physics system.

so what should I do now?

no doubt.

If what Xu Yun said is true, then this news must not spread!

That is to say, the experiment is still to be done, but it must not be carried out in the current environment where the melon-eating parties get together.

Otherwise, if it is spread by those who don't know why and love to exaggerate, tomorrow may be the end of the world.

The worst worst case will also be announced at the physics conference.

Looking at Lao Fa who looked like he was facing a formidable enemy, Xu Yun could roughly understand his feelings.

After all, in his previous life, he was said to be a fisherman in this way, and he was said to have a rich nightlife after having sex all night long. In the end, those group members pretended nothing happened

Think here.

Xu Yun pondered for a while, organized a language, and said:

"Don't worry, Mr. Faraday, the main purpose of this experiment is to support the theory of microparticles that are getting smaller and smaller."

"Although it may have a little bit of impact on the classical physical system, it will not cause the entire system to collapse completely, and it is even less likely that the efforts of the sages will be in vain."

Although Xu Yun paused, he decided to release something more:

"In his suicide note, Patriarch Fat Fish called the world visible to the naked eye the macroscopic world."

"The concepts we have summed up from the macro world, as long as there is no problem in the macro field."

"You say so, Mr. Faraday?"

Old Fa nodded half understanding.

Although he couldn't find the problem in Xu Yun's words, he always seemed to feel that something was wrong?

Maybe I thought too much.

Afterwards, Xu Yun took Lao Fa and others for a while and came to the side of the equipment that Lao Tang had tinkered with.

This set of equipment covers an area about the size of a piano, and it is divided into two parts, which are much more sophisticated than the previous two experiments.

The first part is an electric spark generator.

There are two large copper balls on the generator as capacitors, which are connected to two small copper balls very close to each other through copper rods.

Wire extends from two small balls and is wound around the ends of a large induction coil.

It was then connected to a medinger battery, linking the device together as a whole. (I'll see if this chapter says I can post a picture)

The second part is a receiver, not far from the generator.

It consists of two open rectangular copper rings, each with a small copper ball inlaid at the interface of the copper rings.

As for between the generator and the receiver, a metal plate is placed.

The generator, the receiver and the metal plate form a triangle, and the connection line between the generator and the receiver is the base of the triangle.

The old man walked up to the equipment as before, and his eyes quickly locked on the part where the induction coil was wound:

The number of turns of this induction coil is very large, and it is about as thick as the waist of the ear, occupying a considerable area.

Judging from the old method's years of experience in dealing with electromagnetism.

If the wire gauge is normal, this induction coil should be able to emit a voltage of more than 10,000 volts.

Ten thousand volts is not a small number.

What is this for?

You can't perform electric shock play, right?

Just as Lao Fa was meditating.

William Whewell also came up, and now that he was not under pressure, he became very interested in Xu Yun's experiment.

He circled the receiver first, then let out a sigh:

"Huh? Mr. Faraday, did you forget to connect the wires to the device on the right?"

Lao Fa pondered for a moment, then shook his head lightly:

"It's not that I forgot to connect, but that it doesn't need wires."

William Whewell was taken aback when he heard the words, blinked, and asked:

"Why, have you seen the principle of this equipment?"

Lao Fa adjusted his glasses, without nodding or shaking his head, hesitatingly said:

"It's just some speculation."

Then he pointed to the metal plate not far away, and said:

"Dean Whewell, you are relatively seldom involved in front-line research, so you may not know some things well."

"The imaging plates we often use in optical experiments are generally composite plates made of marble, mainly for the purpose of clearly displaying images."

"As for metal plates of this kind of material, they are more commonly used in reflection experiments, such as sound waves or light, etc."

"Luo Feng asked the experiment to be carried out under dark conditions, so it must have something to do with light."

"So I think that this metal plate should be used to reflect light."

As he spoke, he glanced at the equipment again, touched his chin, and finally set his tone:

"So if there is no accident, this set of equipment should be energized to emit light when the coil equipment is first energized, and then the light is reflected by the metal plate, showing some kind of image on the receiver"

Looking at Lao Fa who was talking eloquently, Xu Yun couldn't help shaking his head slightly.

Old method, old method, you may guess wrong this time.

This experiment has nothing to do with optical imaging.

Of course.

It's no wonder Lao Fa.

After all, the phenomenon of this experiment is too bizarre, far exceeding people's cognition at that time.

One can easily repeat this experiment countless times and be agonized over how it works.

It was not until 20 years after its discovery that Einstein completed the theoretical analysis.

In the present 1850's.

If someone could predict the result of the experiment just by looking at the equipment, Xu Yun would eat the ax in Mai Mai's dormitory on the spot!

However, just as he was about to speak, a voice suddenly froze his expression on his face:

"That...Professor Faraday, is there a possibility that there will be no imaging effect on the receiver, but a potential difference?"

"?????"

Xu Yun turned his head in bewilderment, and found that the person who made the sound was less than three meters away from him.

wheat!

Where did he come from?

Oh, I remembered.

This Scottish youth was originally a student representative watching plays and eating melons, but was captured by Xu Yun during the photovoltaic phenomenon experiment and became a tool man in charge of holding a flashlight.

So naturally.

After the photovoltaic phenomenon experiment was over, he followed the professors to the third round of experiments in a naive manner.

Of course.

What surprised Xu Yun was not that Mai Mai would appear here, nor was he brave enough to put forward an opinion contrary to the old law, but that

What he said.

This moment.

Xu Yun really wants to say MMP, you are here to tear down my station, right?

Why in 1850, someone could imagine specific experimental phenomena just by looking at a few experimental equipment?

Where is the Scythe of Judgment?

I want to report someone cheating!

But soon.

After thinking about the origin of wheat and this experiment, Xu Yun gradually calmed down.

Instead.

It is an indescribable emotion.

This counts.

Doomed vibes?

After all, in the original history.

The result of this experiment is the last wish that Xiaomai longed for all his life, but never met until his death.

Perhaps in the dark, some people and things are innately different from ordinary people.

And the other side.

Mai Mai's words also caught Lao Fa's attention.

Seeing that Lao Fa looked at Mai, William Whewell took the initiative to introduce:

"Mr. Faraday, this is Maxwell's classmate, and the second student approved by Trinity College after Sir Newton."

"Oh? That Scottish genius?"

Lao Fa looked at the wheat with great interest, and asked curiously:

"Student Maxwell, why do you think that there will be no image on the receiver, but a potential difference?"

Mai Mai is a social fear, not to mention the pressure in front of a big boss like Lao Fa, the whole person looks cautious:

"Mr. Farfaraday, I can't explain the specific reason. I can't explain it, but I subconsciously thought of the possibility of potential difference."

Seeing that Mai Mai was about to cry in embarrassment, Xu Yun couldn't help coughing lightly, and came forward to rescue him:

"Mr. Faraday, we have limited time, don't you see?"

Old Fa was taken aback when he heard the words, and then realized that he and William Swan were a little rude.

After all, Prince Albert is still on the sidelines.

So he hurriedly took half a step back, and said to Xu Yun:

"Sorry, sorry, please start, student Luo Feng."

Xu Yun thanked him, and nodded in several directions around him like a conductor who just came on stage.

Walked to the side of the device and turned on the power.

Nourishing——

With the switch closed.

An invisible electric current passes through the induction coil in the device and begins to charge the copper ball capacitor.

1 volt

100 volts

300 volts

1000 volts

When the voltage rises to 20,000 volts.

call out--

The air between the two small balls is instantly broken down.

A large amount of charge began to travel between the two large copper balls, and a high-frequency oscillating circuit was formed.

A few more seconds passed.

Snapped--

A bunch of blue electric sparks burst between two copper balls.

The tiny current beams are constantly twisting in the air, which looks like Sister Pao's OP.

Putting it in the anime, it is impossible for some middle school teenagers to say something like "the lightning that dances at your fingertips is my unchanging belief in this life" and so on.

But this process is fleeting.

Because each vibration is accompanied by a small amount of energy loss, the voltage across the capacitor quickly drops below the breakdown value.

See this situation.

The faces of Lao Fa and the others looked very calm, with almost no major fluctuations.

This is a common phenomenon in laboratories. The scientific community in 1850 was no stranger to high-frequency oscillatory circuits, that is, LC circuits.

But the next second.

The facial expressions of Lao Fa and the others suddenly changed dramatically, even a little distorted!

Stokes even came up with a high note comparable to C5, which sounds a little distorted:

"My God, what is this?"

No one had the heart to laugh at Stokes' duck voice. At this moment, everyone's eyes were focused on the receiver not far away:

Only at this moment.

Every time the generator emits a blue electric spark, there will be an electric flash between the copper rings on the receiver!

Under the pull of some unknown force, there is no receiver connected to the wire.

There is an electric current!

Lao Fa even walked up to the receiver as if no one else was there, looked at the flickering sparks at close range, and murmured:

"Jesus."

The whole process lasted for several minutes. Finally, Xu Yun guessed that the effect was almost done, so he stepped forward and turned off the switch.

The scene was silent, and it looked like a time-stop in a small movie.

After a while.

Lao Fa paced back to the crowd, looked at Mai Mai with complicated eyes, and said:

"Student Maxwell, your guess is correct, there is a potential difference on the receiver."

Mai Mai foolishly scratched her hair, laughing non-stop.

Afterwards, Lao Fa looked at Xu Yun again, the meaning in his eyes was unclear.

This is how many times he was surprised by this oriental man today?

Indeed.

Although these experiments are all due to Fat Fish, Xu Yun is able to reproduce them proficiently, so there is no need to say more about the relevant theoretical level.

He had heard from Whewell that Xu Yun used Mavericks' handwritten letter in exchange for a place in the school. Although he didn't say anything, he still felt that this person was not "compelling".

But now it seems.

I was wrong very outrageously outrageous.

Then Lao Fa took a deep breath, pulled his mind back to reality, and asked Xu Yun:

"Student Luo Feng, what is this phenomenon called?"

Didn't ask the reason, which shows that Lao Fa has already figured out many things in this short period of time.

Xu Yun was silent for a moment, and said a name:

"The photoelectric effect."

That's right.

The experiment that Xu Yun selected in the third round was precisely the famous photoelectric effect!

Throughout the history of human science.

There are only two phenomena that can really be called the core evidence against the volatility theory:

Compton effect and photoelectric effect.

Among them, the Compton effect needs X-ray assistance, and the technology tree of the copy has not yet reached that level.

Therefore, at the very beginning of the incident, Xu Yun's options had actually been determined.

The photoelectric effect is a phenomenon discovered by Hertz in 1887 and finally explained by Einstein.

Actually.

The photoelectric effect is very simple in interpretation.

It is to irradiate the metal plate with light, and the electrons inside some substances will escape to form an electric current after absorbing energy.

That is, photoelectricity.

The photoelectric effect experiments in schools of later generations generally use a zinc plate as the main body of the demonstration, followed by an electroscope that can open and close.

Then the teacher irradiates the metal plate with light, and the electroscope will gradually open, which means that the light generates electricity.

A more responsible teacher will also take out a negatively charged rod with a ground fur belt. After touching the electroscope, the electroscope will close, which means that the metal is positively charged.

But in fact.

The significance of the photoelectric effect is far more than that simple on the surface.

Otherwise, Xu Yun would not be able to discuss another photoelectric effect after finishing the photovoltaic effect:

Although everyone in later generations knows that the photovoltaic effect and the photoelectric effect are two different things, one is the surface and the other is the interior.

But in 1850, when this kind of electron was not discovered, the two are actually somewhat similar in phenomenon.

Again.

Xu Yun's goal is to shake the classical physics building by a billion points

The current situation is shocking enough, but it is far from shocking the physics building.

The line of sight returns to reality.

"Photoelectric effect."

Lao Fa repeated the word with a thoughtful expression:

"Photoelectricity, Electrochemical Light is such a good name."

But after thinking about it, Lao Fa suddenly frowned and realized a certain problem:

"Wait, classmate Luo Feng, isn't it right?"

"Although the photoelectric effect is an amazing phenomenon, strictly speaking, it seems to belong to the extension of the photovoltaic effect in the air."

"It can neither refute the theory of light fluctuations nor have much impact on the existing physical system, so what you said before"

Hearing what Lao Fa said, the rest of the professors on the side also had some aftertaste.

yes.

Before hearing what Xu Yun said was so serious, they thought it would involve the reshaping of the Three Views, and the existing scientific framework would collapse if the existing scientific framework was not maintained.

Among them, some of the professors with better brains are even ready to 'martyrdom'.

result

That's it?

Looking at the puzzled old Fa, Xu Yun didn't explain too much.

Instead, he took something from Mai Mai's hand, put it in his palm, and stretched it out in front of Old Fa:

"Mr. Faraday, don't worry, let's take a look at this thing first?"
