[Overturning the foundation of the physics building].
Hearing these words spoken by Xu Yun.
Laofa's face was stunned at first.
Immediately he thought of something and quickly glanced at the bustling melon-eating party around him.
Then he pulled Xu Yun aside and 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 our existing physical system... be completely overthrown?"
Finished.
He stared at Xu Yun, waiting for the young man's reply.
If someone had said this to him in half a day... No, if someone had said this to him in front of Old Fa two hours ago, he would not have believed even a single punctuation mark.
Are you kidding me?
Modern physics began to gradually establish its foundation in the 15th century, and it has been more than 400 years so far.
Thanks to the efforts of pioneers such as Kepler, Mavericks, Franklin, and Ampere, physics today is considered a very mature subject.
Leading physicists such as Faraday recently planned to jointly submit a letter suggesting that the Royal Society separate physics from chemistry and establish it as an independent discipline.
under such circumstances.
Some people brazenly claim that they can overturn the building of physics. I am afraid that everyone will find it absurd and ridiculous.
But now...
Whether it is the speed of light measured in the first experiment or the photovoltaic phenomenon that is still bubbling, they all prove one thing:
Xu Yun is probably telling the truth.
After all, there is a fat fish behind him who is endorsing him.
Therefore, as the current leader in the physics community, Laofa has to consider some extreme situations:
If, what if, what if, Xu Yun really makes a super, super, huge news that completely negates 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, experiments must still be done, but they must not be conducted in the current environment where the melon-eaters gather together.
Otherwise, if it is spread by those who are ignorant and love to exaggerate, tomorrow may be the end of the world.
The worst-case scenario will also be announced at a physics conference.
Looking at Lao Fa who looked like he was facing a formidable enemy, Xu Yun could roughly understand his mood.
After all, this is how he was rumored to be a fisherman in his previous life. Having sex all night long was said to be a rich nightlife. In the end, the group members pretended that nothing happened...
Think of this.
Xu Yun pondered for a while, composed a sentence, and said:
"Don't worry, Mr. Faraday, the main purpose of this experiment is to support the declining particle theory."
"Although it may have hundreds of millions of impacts on the classical physics system, it will not cause the entire system to completely collapse, and it is even less likely that the efforts of the forefathers will be in vain."
Although Xu Yun paused and decided to release something more:
"In his suicide note, the Fat Fish Ancestor called the world that people can see with the naked eye the macroscopic world."
"The concepts we summarize from the macro world only need to ensure that there are no problems in the macro field."
"Do you think so, Mr. Faraday?"
Lao Fa nodded in understanding.
Although he couldn't find the problem in Xu Yun's words, he always seemed to feel that something was wrong?
Maybe I think too much...
Then Xu Yun took Lao Fa and others forward for a while and came to the equipment that Lao Tang tinkered with.
This equipment covers an area about the size of a piano and is divided into two parts. It is 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.
Wires extend from two small balls and are wrapped around the ends of a large induction coil.
It was then connected to a Medinger battery, tying the device together. (I’ll see if I can post pictures in this chapter)
The second part is a receiver, not far from the generator.
It consists of two open rectangular copper rings, with a small copper ball inlaid at the interface of the copper rings.
As for the generator and receiver, a metal plate is placed.
The generator, receiver and metal plate form a triangle, and the connection between the generator and the receiver is the base of the triangle.
Laofa walked up to the device as if he was still present, and his eyes quickly locked on the part where the induction coil was wrapped:
The number of turns of this induction coil is very large. Visually, it is about as thick as the waist of the ear, and it occupies a quite large area.
Judging from Lao Fa’s long-term experience in dealing with electromagnetism.
If the wire specifications are 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 deep in thought.
William Whewell also came up. Now that he was no longer under pressure, he became very interested in Xu Yun's experiments.
He first circled the receiver, and then said softly:
"Huh? Mr. Faraday, did you forget to connect the wires to the equipment on the right?"
Lao Fa pondered for a moment and shook his head gently:
"It's probably not that I forgot to connect it, but that it doesn't need wires in the first place."
William Whewell was stunned when he heard this, blinked, and asked:
"Why, do you understand the principle of this equipment?"
Laofa adjusted his glasses and said hesitantly without nodding or shaking his head:
"It's just some speculation..."
Then he pointed to the metal plate not far away and said:
"Dean Whewell, you are less involved in front-line research, so you may not know much about some situations."
"The imaging plates we commonly use in optical experiments are generally composite plates made of marble, mainly to display images clearly."
"As for metal plates made of this kind of material, they are more common in reflection experiments, such as sound waves or light, etc..."
"Luo Feng requested that the experiment be conducted under dark conditions, so it must be related to light."
"So I thought the metal plate was supposed to reflect light."
As he spoke, he glanced at the equipment again, touched his chin, and finally settled on the tone:
"So if nothing else, this equipment should be powered by the coil device to emit light first, and then the light is reflected by the metal plate, showing some kind of image on the receiver..."
Seeing Lao Fa talking eloquently, Xu Yun on the side couldn't help but shook his head gently.
Old Fa, Old Fa, you guessed wrong this time.
This experiment has nothing to do with optical imaging.
Of course.
This can’t be blamed on Lao Fa.
After all, the phenomenon of this experiment was so bizarre that it far exceeded people's understanding at the time.
People can easily repeat this experiment countless times, but they are still troubled by its principle.
It was not until 20 years after its discovery that Einstein completed the theoretical analysis.
In the current year of 1850.
If someone could predict the results of the experiment just by looking at the equipment, Xu Yun would have eaten the ax in Wheat's dormitory on the spot!
However, just as he was about to speak, a voice suddenly froze his expression:
"Um...Professor Faraday, is it possible that there will be no imaging effect on the receiver, but a potential difference?"
"????"
Xu Yun turned his head in confusion and found that the person who made the noise was less than three meters away from him. It was...
wheat!
Where did he come from?
Oh, I remembered it.
This young Scottish man originally watched the show as a student representative, but was captured by Xu Yun during the photovoltaic phenomenon experiment and became the tool man responsible for holding a flashlight.
So naturally.
After the photovoltaic phenomenon experiment ended, he innocently followed the professors to the venue for the third round of experiments.
Of course.
What surprised Xu Yun was not that Xiaomai would appear here, nor that he had the courage to put forward opinions contrary to Lao Fa, but...
What he said.
At this moment.
Xu Yun really wants to say MMP, you are here to tear me down, right...
Why could someone predict specific experimental phenomena in 1850 just by looking at a few experimental equipment...
Where is the Scythe of Judgment?
I want to report someone for cheating!
But soon.
After thinking about the connection between wheat and this experiment, Xu Yun gradually began to calm down.
Instead.
It was an indescribable emotion.
This is...
Destined resonance?
After all, in the original history.
The result of this experiment was the last wish that Xiaomai had longed for all his life but had never seen until his death. At the same time, it also rectified the name of Xiaomai after his death.
Maybe somewhere down the line, the compatibility between some people and things is innately different from ordinary people.
And the other side.
Wheat’s words also attracted Lao Fa’s attention.
Seeing Lao Fa looking at Xiaomai, William Whewell took the initiative to introduce:
"Mr. Faraday, this is Maxwell's classmate, and he is also the second student approved by Trinity College to reduce fees after Sir Isaac Newton."
"Oh? Is that the Scottish genius?"
Lao Fa looked at the wheat with great interest and asked curiously:
"Classmate Maxwell, why do you think that there will be no image on the receiver, but a potential difference?"
Xiaomai is a social phobia, not to mention the pressure in front of a big boss like Lao Fa. He looks very reserved:
"F... Mr. Faraday, I don't understand the specific reason... I can't explain it. I just subconsciously thought of the possibility of electric potential difference..."
Seeing that Xiaomai was about to cry, Xu Yun couldn't help but cough slightly and stepped forward to rescue him:
"Mr. Faraday, our time is limited, do you think..."
Old Fa was stunned when he heard this, and then he realized that he and William Huiwei were a little rude.
After all, Prince Albert is still around.
So he quickly took half a step back and said to Xu Yun:
"Sorry, sorry, please start, classmate Luo Feng."
Xu Yun thanked him and nodded in several directions around him like a conductor who had just taken the stage.
Walked to the device and turned on the power.
Zhi——
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 balls was instantly penetrated.
A large amount of electric charge began to flow between the two large copper balls, and a high-frequency oscillation circuit was formed.
A few more seconds passed.
Snapped--
A bouquet of blue electric flowers exploded between two copper balls.
The small beam of electricity kept twisting in the air, looking like Sister Cannon's OP.
In anime, I wonder if some middle school boys would say something like, "The electric light dancing on your fingertips is my unchanging faith in this life."
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 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 oscillating circuits...that is, LC circuits.
But the next second.
The facial expressions of Lao Fa and others suddenly changed dramatically, even...a little distorted!
Stokes even played a high note comparable to the key of C5, which sounded a little distorted:
"Oh my god, what is this?"
No one had the intention to laugh at Stokes' duck voice. At this time, everyone's eyes were focused on the receiver not far away:
I only see this moment.
Every time the generator emits a blue electric spark, there will be a flash of electric light between the copper rings on the receiver!
Pulled by some unknown force, the receiver did not connect to the wire...
There is electricity!
Lao Fa even walked to the receiver as if no one else was around, looked at the flickering sparks at close range, and murmured:
"Jesus..."
The whole process lasted for several minutes. Finally, Xu Yun estimated that the effect was almost complete, so he stepped forward and turned off the switch.
The scene was silent, and it looked like a moment in a short movie.
After a while.
Lao Fa walked back to the crowd, looked at Xiaomai with complex eyes, and said:
"Classmate Maxwell, your guess is correct, there is a potential difference on the receiver."
Xiaomai scratched his hair naively and laughed non-stop.
Then Lao Fa looked at Xu Yun again, his gaze meaning unclear.
Is this the first time today that he has been surprised by this Oriental?
True.
Although these experiments are all attributed to Fat Fish, Xu Yun was able to reproduce them skillfully, so there is no need to say more about the relevant theoretical level.
He had heard from Whewell that Xu Yun had used Maverick's autographed letter to exchange for an admission spot. Although he didn't say it, he still felt that this person was a bit unscrupulous.
But now it seems...
I was very, very wrong.
Then Lao Fa took a deep breath, brought his mind back to reality, and asked Xu Yun:
"Classmate Luo Feng, what is this phenomenon called?"
Not asking why, it shows that Lao Fa has figured out a lot of things in this short period of time.
Xu Yun was silent for a moment and said a name:
"Photoelectric Effect."
That's right.
The experiment Xu Yun chose in the third round was the famous photoelectric effect!
Throughout the history of human science.
There are only two phenomena that can really be called core evidence to refute the wave theory:
Compton effect and photoelectric effect.
Among them, the Compton effect requires X-ray assistance, and the technology tree of the current copy has not reached that level.
Therefore, at the very beginning of the incident, Xu Yun's options were actually determined.
The photoelectric effect is a phenomenon discovered by Hertz in 1887 and ultimately explained by Einstein.
Actually.
The photoelectric effect is simple in meaning.
It is to illuminate the metal plate with light. After the electrons inside certain substances absorb energy, they will escape and form an electric current.
That is photoelectricity.
Photoelectric effect experiments in later schools generally used a zinc plate as the main body of the demonstration, with an electroscope that could open and close connected to the back.
Then the teacher illuminates the metal plate with light, and the electroscope will gradually open, which means that the light generates electricity.
The more responsible teacher will also take out a rod that has been rubbed with fur and has a negative charge. 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 goes far beyond its apparent simplicity.
Otherwise, Xu Yun would not have bothered to talk about the 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 an era like 1850 when electrons were not discovered, the two phenomena were actually somewhat similar.
Again.
Xu Yun's goal is to shake the classical physics building by hundreds of millions...
The current situation is shocking enough, but it is still far from shocking the physics building.
His eyes returned to reality.
"Photoelectric effect..."
Lao Fa repeated the word with a thoughtful expression:
"Photoelectricity, electrochemical light...what a good name..."
But after thinking about it, Lao Fa suddenly frowned and realized a certain problem:
"Wait a minute, classmate Luo Feng, isn't that right?"
"Although the photoelectric effect is an amazing phenomenon, strictly speaking, it seems to be just an extension of the photovoltaic effect in the air."
"It can neither refute the wave theory of light nor have much impact on the existing physical system. So what you said before..."
Hearing what Lao Fa said, the other professors on the side also came to their senses.
yes.
Having heard Xu Yun speak so seriously before, they thought it would involve the reshaping of three views, and that the existing scientific framework would collapse if it could not be maintained.
Some of the professors who are more powerful in thinking are even ready to be martyred.
result......
That's it?
Looking at Lao Fa who looked confused, Xu Yun didn't explain too much.
Instead, he took something from Wheat's hand, put it in his palm, and stretched it out in front of Old Fa:
"Mr. Faraday, don't worry, why don't you take a look at this thing first?"
.........
Note:
My schedule these days is very hellish, I wake up at 6pm and 11pm, etc., so the update time will be a bit messy.
In addition, I heard that Qidian has solved some blocked words, including one of our old tricks. Try it here.
