Chapter 488 Terrifying electromagnetic energy! The electric light dancing on your fingertips is my eternal faith in this life!
The people attending the lecture today include almost the best scientific talents in Italy.
Their level is at the top of this era, and their knowledge is the broadest.
When Li Qiwei mentioned Avogadro, everyone's hearts shook and they felt so proud.
It's like when Chinese people go abroad and hear foreigners praising the Nine Chapters arithmetic.
It was a sense of national pride.
And now, as Li Qiwei, that is even more remarkable.
Whether it is the mass-energy equation or Fermi's kinetic energy attack, they are all based on Professor Bruce's special theory of relativity.
But now, the other party himself mentioned and admired local Italian scientists.
This move instantly turned everyone in the venue into fans.
"Professor Bruce knows the history of science in Italy very well, and he recognized Italy's contribution to science."
"It's so sad! When will Italy's scientific glory be restored?"
"Professor Bruce really does as the Romans do."
"I just want to know, what does Avogadro have to do with the destruction of the earth? Does he have any hidden achievements that he has not yet published?"
After feeling proud, everyone began to make random guesses.
But Pauli frowned after hearing Avogadro's name.
He murmured:
"Is it Avogadro's constant?"
"Although the number NA is large, the water film just now proved that the number of atoms in a drop of water is not enough to cover the earth."
"Otherwise, Avogadro's results will probably be useless."
Pauli was a little puzzled.
suddenly!
He had a flash of inspiration!
wrong!
In addition to the number of atoms in a drop of water, there is another thing that is also NA-level.
Maybe that's the answer!
Pauli quickly took out his pen and paper and started calculating.
If it is as he expected, then the calculation is a little more complicated.
With his level, Keke can't figure it out, only Dirac can do it.
Under the eager gazes of everyone, Li Qiwei finally spoke.
"My answer is different from Fermi's."
"Fermi used external forces, but I used the properties of a drop of water itself."
"That's charge!"
Wow!
Everyone was shocked!
This idea caught everyone by surprise.
"Charge? How much charge can a drop of water have? How can it destroy the earth!"
"Well, a drop of water seems to have a lot of charges, but what is the use of these charges? The total amount is very small."
"Professor Bruce is really different from ordinary people. His ideas are always so wild and unconstrained."
However, most people were not immediately excited.
Because they can't figure out what the charge of a drop of water can do or how it can destroy the earth.
When Pauli heard this, his eyes flashed!
"It's exactly what I thought!"
"Professor Bruce and I have a good connection!"
Li Qiwei smiled softly and continued:
"My plan is to remove all the electrons from a drop of water in an instant."
hiss!
As soon as this statement came out, the venue was in shock!
What does this mean?
Everyone was immediately stunned.
"Oh my God, what happens if you remove an electron from a drop of water?"
"Can this destroy the world?"
"There is so much water in the ocean that evaporates into space every day, and the earth is not destroyed."
“I can’t understand it at all.”
"."
At this moment, many geniuses who were known as outstanding students in the school were also dumbfounded.
They couldn't figure out what Professor Bruce's answer meant.
Remove electrons from a drop of water?
Could this have any big impact?
It doesn't feel like it has any impact.
Even many professors feel confused.
Vecchio looked puzzled.
"Does Professor Bruce want to rely on the electromagnetic energy of a drop of water itself?"
"But how can electromagnetic energy be compared with the conversion of the mass-energy equation?"
"The two are not of the same order of magnitude."
Vecchio shook his head slightly, puzzled.
However, Fermi was suddenly startled. Like Pauli, he seemed to have grasped the key point.
"Could it be that you want to affect the voltage or potential of the entire earth through the transfer of electric charges?"
Oh my God!
What a bold idea!
Under the confused expressions of everyone, Li Qiwei said again:
"I also used the data of the first classmate."
"Suppose the volume of this drop of water is 0.05 ml, then the mass is 0.05 grams."
"Converted into moles, that is about 0.0028 mol of water molecules."
"So, the total number of electrons contained in this drop of water is 0.0028×NA=0.168×10."
"It is known that the charge of a single electron is 1.6×10 (negative 19th power) Coulomb."
"Then the total charge of the electrons contained in a drop of water is 2688 coulombs."
"If I remove all the electrons in the water droplet and disappear in an instant, the electric potential of the earth will change."
"Using Pauli's data just now, the radius of the Earth is 6,300 kilometers."
"Then, according to the electric potential formula φ=kQ/r, and substituting the data, we can get: φ=3800000 volts."
"That is, the electrical potential of the earth will increase by 3.8 million volts."
"Once the earth's electric potential rises, it will inevitably cause changes in the earth's magnetic field."
"Changes in the Earth's magnetic field will not only cause violent activities such as earthquakes and tsunamis, but also affect the activity of the solar wind."
"Once the Earth's atmosphere and magnetic field cannot block the solar wind, the Earth will continue to be impacted by the solar wind."
"Sooner or later, the entire earth will be destroyed!"
"Of course, it is impossible for us to just remove the electrons from the water and keep the water molecules unchanged."
"Because if there are no electrons, the atoms will instantly disintegrate and cease to exist."
"According to calculations from classical electromagnetism, the energy generated by this process is approximately 8×10 (18th power) Joules, which is equivalent to 2 billion tons of TNT."
"In other words, it takes so much energy to remove all the electrons from a drop of water."
quiet!
Deathly silence!
When Li Qiwei finished his answer, the entire hall was so silent that you could hear a pin drop.
Everyone's eyes widened with disbelief on their faces.
They were in extreme shock!
A drop of water can have such a big impact on the earth.
It is simply unheard of, like a fantasy, and it is beyond common sense.
What an exaggeration!
I don’t know how much time passed.
There was a roar in the hall and it was boiling.
Everyone started a heated discussion.
"Oh my God! This is incredible! Can a drop of water increase the electrical potential of the entire earth by millions of volts?"
"Then if there were a little more, wouldn't it be able to reach hundreds of millions of volts!"
"This is the real imagination!"
"No wonder Professor Bruce didn't like Fermi's answer."
"His answer was so cool, like something out of a science fiction novel."
"Aliens came to the earth, took only a drop of water, and destroyed the earth, but the people on earth still don't know what happened."
"."
The atmosphere in the hall reached its climax at this moment.
Professor Bruce's answer exceeded everyone's imagination. When everyone was applying various high-level theories, he actually chose electromagnetism from classical physics.
Turn decay into magic!
If a foreigner knew this Chinese saying, he would definitely not be able to resist saying it.
However, this answer is a bit difficult to understand, so someone asked:
"Professor Bruce, I have a question."
"If the electromagnetic energy equivalent to 2 billion tons of TNT is contained in this drop of water, wouldn't it contradict the special theory of relativity?"
"Because the energy in the mass-energy equation should be all the energy of the object itself."
"How can it be so much smaller than electromagnetic energy?"
"I don't understand this."
At this time, Li Qiwei smiled slightly and glanced at Pauli.
Please...you...Collect_6Ⅰ9ⅠBookⅠ(Six\\\Nine\\\Book\\\!)
"Close the door and put Pauli in!"
Pauli understood it instantly, and he immediately explained:
"The electromagnetic energy that Professor Bruce mentioned does not actually come from the water itself, so it has nothing to do with the mass-energy equation."
"Let me give you a vivid example."
"It's like you lift an apple to a very high height, the apple itself doesn't change."
"But at this moment, it has a very high gravitational potential energy."
"Once you do it, the apple will fall to the ground and produce impact."
"The same is true for taking out all the electrons in a drop of water. You need to overcome the electrical potential energy in the huge system of the earth and electrons."
"If it is taken out in an instant, the energy equivalent to 2 billion tons of TNT will be concentrated in a drop of water and explode."
"It is impossible to imagine what the real situation of this explosion is."
"Of course, it is impossible for humans to have such technology at present."
"Perhaps only the advanced civilizations in "Bugs" can have such incredible technology."
Although Pauli has a bad mouth, there is no doubt about his strength.
His explanation was very clear to everyone.
The terrifying electromagnetic energy contained in a drop of water does not come from itself, but from the earth system.
But this energy is closely related to water droplets and is indispensable.
So strictly speaking, the answer depends on the properties of the water drop itself.
At this time, someone asked again:
"Then if one day in the future, humans can land on the moon, wouldn't this happen if a drop of water is brought to the moon?"
When Pauli heard this, he almost jumped up and cursed.
However, in this situation, he still answered patiently:
"This situation is different from what Professor Bruce said."
"Bringing a drop of water from the earth to the moon will not cause any change in the electrical potential of the earth itself."
"Because that drop of water is neutral, when you take away electrons, protons are also taken away."
"Only the gravitational potential energy changes."
The questioner suddenly realized that he had made a common sense joke, and he quickly sat down and covered his face in shame.
Many people present did not know Pauli, and Li Qiwei did not go out of his way to introduce him.
So everyone regarded Pauli as a student brought by Professor Bruce.
"The Institute of Quantum is really full of talents, and any young person is so awesome."
"I think he is crazier than Professor Bruce."
Femi heard everyone's discussion and smiled secretly.
If they knew Pauli's true identity, they would probably be shocked.
Soon, everyone no longer had any problems.
They were all shocked by the terror of electromagnetic energy.
If a person could move electrons around at will, he would be virtually invincible!
All she needs is a coin, toss it up:
"The electric light dancing on your fingertips is my eternal faith in this life!"
"Only my railgun will last forever!"
This is the charm of electromagnetic energy.
Femi smiled softly.
He finally understood why Professor Bruce didn't like his answer.
Comparing the two, one is a gentleman and the other is a reckless man.
Normal people would never imagine that just one drop of electrons in water would have such a big impact on the earth's electric potential.
Totally counterintuitive.
It is simply the same as the original special theory of relativity.
As for what Professor Bruce said later, will changes in electric potential cause magnetic field changes, solar wind attacks, etc.
These are actually not very important.
Maybe the earth is still fine, but it's just become riddled with holes.
The gold content of this idea is enough to make up for all the shortcomings.
It's wonderful.
Fermi smiled bitterly:
"I'm willing to give up!"
Croce's mouth remained open. He was in a state of complete confusion.
Li Qiwei's answer shocked him deeply.
Even the whole speech shocked him from the beginning to now.
"You really can't mess with scientists."
"They are thinking about how to destroy the world every day."
"The key is, there are several ways."
"One drop of water is enough."
"So scary!"
At this moment, everyone seemed to see a tyrannical figure, spanning the universe and reflecting the heavens!
He just pointed a finger, and a tiny drop of water jumped up and floated above the earth.
"Go!"
Ba Ying gives an order!
The water droplets spin wildly!
Countless electrons invisible to the naked eye are shot out rapidly.
Suddenly, the earth seemed like the beginning of the world, with lightning flashing and hurricanes raging, as if the end of the world was coming.
boom!
Destroy the stars with a snap of your fingers!
Li Qiwei looked at everyone's surprised expressions and smiled slightly.
Electromagnetic force is the force most closely related to human beings, but people's understanding of it is far from sufficient.
It not only makes our world rich and colorful, but also contains dangers that can destroy everything.
Of course, due to unknown confinement reasons, the link between electrons and protons is extremely stable.
Perhaps this is what the Creator intended.
A drop of water is like this. If it is more extreme, it can instantly remove the electrons of the entire earth.
Then this energy is enough to destroy one-fiftieth of the observable universe.
Just when everyone was immersed in the power of electromagnetic energy, Li Qiwei suddenly said:
"Through this question, I actually want to introduce the topic of today's speech."
"That's the electron."
"It is the core of quantum theory."
"The entire Bohr-Lee model and the four large quantum numbers are actually explaining various behaviors of electrons."
"By understanding electrons, our understanding of the microscopic world will go one step further."
"And by understanding the micro, we can understand the macro more deeply."
"Just like the question just now, I actually have another answer."
"But I want to keep this answer secret for now."
"Because it is related to the International Astronomical Congress I will attend next."
"At that conference, I will share my latest research results."
"According to my theory, a drop of water may destroy the earth in another way."
"So, please wait and see and pay more attention to the astronomical conference in a few days."
boom!
Everyone was shocked!
