Into Unscientific Chapter 255

  Chapter 255 People are in Cambridge, waving their sleeves, attracting a dark cloud (Part 1)

  【Overthrow the foundation of the physics building】.

   Hearing the words Xu Yun said.

  Old Fa was taken aback for a moment.

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

   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 speaking.

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

  If it was half a day. No, if someone said this to him in front of Lao Fa two hours ago, he would never believe even a single punctuation mark.

  Are you kidding me?

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

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

   These head 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 all proves one thing:

   What Xu Yun said is probably the truth.

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

   Therefore, as the leader of the current physics world, Lao Fa has to consider some 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, the experiment is still to be done, but it must not be carried out in the current environment where people who eat melons get together.

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

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

  Looking at Lao Fa who looked like an enemy, Xu Yun could roughly understand his feelings.

  After all, in his previous life, he was said to be a fisherman in this way. All night **** was said to be rich in nightlife. 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 gradually declining."

   "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 think too much.

   Then Xu Yun took Lao Fa and others to walk a certain distance, and came to the equipment that Lao Tang had tinkered with.

   This set of equipment occupies an area about the size of a piano. 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 **** on the generator as capacitors, which are connected to two small copper **** that are very close to each other through copper rods.

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

   This is then connected to a medinger battery, linking the set up 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, receiver and metal plate form a triangle, and the line connecting the generator and receiver is the base of the triangle.

  Old Fa still walks in front of the equipment, and his eyes quickly lock on the part where the induction coil is wound:

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

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

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

   Ten thousand volts, this 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. Now that he is not under pressure, he has a strong interest in Xu Yun's experiment.

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

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

  Old 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?"

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

   "Just some guesswork."

   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 much about some situations."

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

   "As for the metal plate of this kind of material, it is more common 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 be related to light."

   "So I think 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 after 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 the eloquent old Fa, Xu Yun couldn't help shaking his head slightly.

  Old Fa, Lao Fa, this time you guessed wrong.

  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 the time.

  One can easily repeat this experiment countless times, but agonize over how it works.

   It was not until 20 years after it was discovered that Einstein completed the theoretical analysis.

  In the current 1850.

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

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

   "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 he 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.

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

   What he said.

   Right now.

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

  Why did someone in 1850, just look at a few experimental equipment, be able to predict specific experimental phenomena?

  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 wheat has longed for all his life, but he never saw it until his death. At the same time, it also corrected the name of wheat after death.

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

   And the other side.

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

   Seeing Lao Fa looking 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?"

  Old Pharaoh 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?"

  Wheat is a social fear, not to mention the pressure in front of a boss like Lao Fa, the whole person looks stiff and not wanting:

   "Mr. Faraday, 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, 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.

  Zi—

   With the switch closed.

  The invisible current passes through the induction coil in the device and starts to charge the copper ball capacitor.

  1 Volt

  100 Volts

  300 Volts

  1000 Volts

  When the voltage rises to 20,000 volts.

   Whoosh—

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

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

  In the anime, it is impossible to guarantee that some middle school teenagers will 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 every vibration is accompanied by a little energy loss, the voltage across the capacitor quickly drops below the breakdown value.

  See this scenario.

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

   This is a common phenomenon in the laboratory. The scientific community in 1850 was no stranger to the high-frequency oscillation circuit, that is, the LC circuit.

   But the next second.

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

  Stokes even came up with a high pitch 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 time, everyone's eyes were focused on the receiver not far away:

  I saw 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!

  Old 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.

  Old 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.

  Later, Lao Fa looked at Xu Yun again, with unclear meaning in his eyes.

   This is the first time he was surprised by this oriental man today?

   True.

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

  At the beginning, he heard from Whewell that Xu Yun exchanged Mavericks' handwritten letter for a place in the school. Although he didn't say anything about it, he still felt that this person was a little "unfortunate".

   But now it seems.

  I was very, very wrong.

  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.

  Xu Yun's third round of experiments was selected for the famous photoelectric effect!

   Throughout the history of human science.

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

  Compton effect and photoelectric effect.

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

  So 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 terms of 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, and an electroscope that can open and close is connected behind it.

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

  Responsible teachers 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 wouldn't be able 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 1850, when electrons were 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."

  Old 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, student 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 wave theory of light, 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.

  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 Maimai'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?"

Note:

  The schedule these days is very dark, waking up at 6:00 pm or 11:00 pm, so the update time will be messy.

  In addition, I heard that Qidian has solved some masked words, including one of our old tricks. Try it here.

  【Seeing the 30,000 daily updates of the author's fungus, the readers had joyful smiles on their faces, and they cast monthly tickets one after another】
