Chen Yazhi stood behind Wang Yi, which was already her habitual position. Today was strange. The girl looked at the two groups of people quarreling curiously, but her eyes were staring at Wang Yi's back, and said in her heart: "These foreigners are so stupid. They were actually quarrels by this kid's words. The brother always said that Europeans emphasize gentlemanly demeanor, which is a lie!"

This is the cafeteria of the primary school affiliated to Dashang. It is now lunchtime. In addition to a group of primary school students, there are also scholars recruited by Wang Yi from abroad. Of course, only a few people have this status, and more are college graduates from poor families - newcomers in society. They were bewitched to the Qing Dynasty, with the goal of making a fortune. Wang Yi was not everyone, at least they could pass his competition and interview.

Perhaps it was because of the phonograph that the Da Shang Group of the Qing Dynasty, which had no one to apply for, suddenly became bustling from the door. In the past six months, it has indeed recruited many good foreign seedlings.

Today, Wang Yi was also a bitchy. A group of people were eating. He had nothing to do but raised the question of what the light was. Of course he knew the answer, but he liked to sow discord. As expected, some scholars believed that light was a flow of particles, and they patiently explained the reason to Wang Yi. The other party was indignantly thinking that light was a wave, so that Wang Yi would not believe the other party's words. To count it, most people in the canteen still support the latter statement.

In history, the theory of fluctuations and particle theory of light experienced two wars. The first time was represented by Newton, who supported the theory of microparticles and Hook, who supported the theory of fluctuations. The two clashed. Newton achieved an overwhelming victory with his identity as a scientific giant and Comrade Hook's early death and exit. The peace continued for a century, and the theory of microparticles occupied an absolute dominance. It was not until the appearance of Thomas Yang, the insurer, that the seemingly solid particle theory of rock-solidity, and the second microwave war broke out.

For the first time, both sides were in a state of anxiety. The supporters of the Weijie Theory could not explain Thomas Yang's interference fringe, while the supporters of the Volatility Theory also had no choice but to use Marius' polarization phenomenon.

The decisive moment occurred in 1819. The French Academy of Sciences held a reward essay contest. Poisson and others, who wanted to raise the momentum of particles, did not expect that Fresnel would come to emerge. He changed his previous understanding of light from longitudinal waves to transverse waves, and successfully used rigorous mathematical reasoning to successfully solve the diffraction of light and the polarization of light that has long been plagued by the fluctuation theory. Later, when the disc diffraction was about the disc, the debate and verification of the highlights in the center of the disc spot (Poisson's bright spot) became the finishing touch. Later, Foucault's test experiment on the speed of light completely eliminated the final hope of the particle theory and directly sentenced to death.

After more than a century of struggle, the volatility theory finally turned over and serfs sang and occupied the throne of the ruler. The subsequent discoveries were mainly the papers on electromagnetic theory published by the great Maxwell in 1856, 1861 and 1865, which even added an important shot to the particle theory. He believed that light was just a type of electromagnetic wave, and the only question now is who will prove the correctness of his prediction.

While a group of foreigners were arguing, Wang Yi pulled Chen Yazhi to her side, and while eating, he told her about the grudges and love between Weili and Booming.

Although Chen Yatou couldn't understand some things, she also understood the general situation, so she no longer felt that the quarrels of foreigners were so incredible. In her heart, she felt that such quarrels were much stronger and cleaner than those in the court.

Scott Williamson is the head of the Sean Glass Test Project in the Materials Department. He came to Wang Yi at this time and said, "Sir, your previous contact with you and your tips on me will let me know that you are one of the greatest scientists in the world, so let's end this debate and listen to your views!"

Everyone turned their attention to Wang Yi, including a group of foreigners who came to China to engage in scientific research from thousands of miles away, as well as elementary school students who were having dinner in this dining room.

Wang Yi thought about it and nodded. For some reason, warm applause suddenly erupted in the entire hall hall. Chen Yazhi, who was originally pulled by Wang Yi, felt excited for no reason at this time, and she felt quite excited with honor and joy. Her white and tender little hands were slapped red.

Everyone here knows Wang Yi because he is not only the principal of the primary school affiliated to Dashang, but also the highest controller of Dashang Industrial Laboratory.

"Today I am here, I will tell you my opinion on what light is..."

The alternation of Mandarin and English is Wang Yi's limit. Although there are some scholars from Germany and France, there are many people around them who can speak both English and German and French, and these people act as temporary translators.

Someone brought in a big blackboard, and Wang Yi said while remembering the blackboard.

He started with the history of optics, and then gradually unfolded. The first microwave war and the second microwave war were full of interesting language. Even those first-grade primary school students who still didn't understand anything were attracted by Wang Yi's story. Whenever Wang Yi told celebrities from a country, the country's scholars would unconsciously show a sense of pride from the heart. Wang Yi understood this feeling, but it was an experience that only happened in later generations. Without returning to the Qing Dynasty, he would never truly understand how great the country he once existed was.

"When Maxwell's three papers on electromagnetic theory say that light is actually just one of electromagnetic waves, then what we have to do now is to verify whether his inference is correct or not!"

Scott Williamson stood up again, bowed slightly, and said, "Sir, you still haven't expressed your opinion!"

Everyone else nodded. After all, the debate about the particle theory of light and the fluctuation theory now seems like a unsolved case filled with strange fog. Although it seems that the truth is revealed, who can be sure that this is not the beginning of another mystery?

Wang Yi smiled at this time and said, "My answer is very simple. In three days, I will wait for everyone in the electromagnetic laboratory."

After saying that, Wang Yi packed up his things and took Chen Yazhi away from the canteen. The rest of the people were stunned. But then everyone became excited again. It seemed that Wang Yi had any major scientific research progress to be announced!

On the way back to the office, Wang Yi walked leisurely in the garden. The girl Chen jumped and followed Wang Yi. After a while of quietness, she finally couldn't help asking.

"Principal, you are so powerful. Do you think this light is correct in fluctuations? Or is the particles correct in correct in terms of particles?"

Wang Yi laughed at this time, then stretched his waist and replied with a smile: "I said, they are all right, and they are not right! Hahahahaha..."

Chen Yazhi was stunned in place, never expecting that Wang Yi would give such an answer. After thinking for a long time, she couldn't figure out the mystery. Finally, she had to stomp her feet hatefully, look at Wang Yi who had already walked away, and hurriedly chased after him. She grimaced at Wang Yi's back from time to time, waved her fists, and muttered constantly: "If you don't tell me, don't tell me! Who cares about it!"

Overall, Wang Yi was very pleased to be able to make Yat-shen angry.

Three days later, in a large laboratory on the second floor of the Electromagnetic Experimental Building, the surrounding windows were pulled with thick black cloth curtains. Wang Yi stood at the door, and the corridor outside the laboratory was already crowded with people.

"How is it, has the experiment begun?" Later scholars asked from time to time because there were too many people.

"It's not started!"

Zhang Jingxiao was standing outside the crowd at this time. He didn't intend to come to the experiment, but he rushed over because of the matter of Dashang Shipyard. Unexpectedly, he encountered such a grand scene. At this time, a young young man of seventeen or eighteen years old was standing next to him, wearing a small hat with emerald green jade inlaid on his head, wearing a brocade robe, gorgeously dressed, and looked quite rich. The white jade ring on his hand alone could be called priceless. He also looked outstanding, with fair skin, but he looked a little bit of powdery.

"Well, this guy is playing with a trick!?"

Zhang Jingxiao frowned, with a very displeased expression.

The man immediately changed his expression when he saw it, "Brother Jingxiao, don't be angry, I won't say it." Although he said that, he still muttered in a low voice: "Who are you lying to me? These foreigners are squeezing and don't bother to sweat."

Wang Yi said to everyone at this time: "Everyone, I know everyone's mood, but the space inside the laboratory is limited, so please queue up to enter." He turned his face and said to Chen Yazhi: "Let ten people enter each time!"

The girl nodded obediently. She had finished watching this experiment and had watched it more than once. Despite this, she still couldn't believe the scene that had appeared in front of her.

Scott Williamson was one of the first ten people to come. When he heard that Chen Yatou asked them to go in, he immediately became excited and inexplicably felt a sense of glory. He didn't know what he was proud of.

Scott and others, who were originally excited, were somewhat depressed after seeing Wang Yi's laboratory arrangement. The laboratory was divided into two pieces by a large black cloth. Just as the part of the experimental equipment that can be seen at present can only be described simply.

An electric spark generator has two small copper balls very close to each other as capacitors.

"Everyone, please watch!" Wang Yi reminded, and at this time he turned on the power switch.

The magic of electricity was revealed, and an invisible current passed through the induction coil in the device and began to charge the capacitance of the two small copper balls. After a while, a blue electric flower flashed between the two copper balls, and the entire system formed a completed circuit. The tiny current beam kept twisting between the copper balls, emitting a faint fluorescence.

Wang Yi walked to the black cloth of the separate laboratory and pulled it apart.

The other half of the laboratory is even simpler than here, with only an open copper ring, and a small copper ball is inlaid at each opening, without any external power supply.

But except for Wang Yi, everyone present could not speak, because blue electric flowers were blooming happily between the two small copper balls with the copper ring opening.

This is the flower of the era that opened up! Faraday laid the foundation for it, Maxwell constructed it, and today Wang Yi sealed the roof for it. It can be said that from today on the electromagnetic theory has been truly established!
Chapter completed!
