Shen Yazhi stood behind Wang Yi, this was already her accustomed position, it was strange today, the girl watched the two groups of people quarreling curiously, but her eyes were staring at Wang Yi's back, and she secretly said in her heart: "These foreigners are really stupid, they were actually caused to quarrel by this kid's words." My brother always said that Europeans pay attention to gentlemanly manners, and they are all lies! ”

This is the cafeteria of the Dashang Affiliated Primary School, and it is now the time for lunch, and 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 are in this capacity, and more are actually some college graduates from poor families - freshmen in society. They were bewitched to come to the Qing Dynasty, and their goal was to make a fortune, and Wang Yi didn't want everyone, at least he could pass his competitions and interviews.

Probably because of the phonograph, the Daqing Dashang Group, which had no one to apply, suddenly became busy from the door. In the past six months, many good foreign seedlings have indeed been recruited.

Today, it is also Wang Yi's mouth, a group of people eat when they eat, but he is okay but provokes the question of what light is. Of course, he knows the answer, but he likes to sow discord. As expected, some scholars believed that light was a stream of fine particles, and they patiently explained the reason to Wang Yi. The other party indignantly thought that light was a kind of wave, and asked Wang Yi not to believe the other party's words, but in real terms, most of the people in the canteen still supported the latter statement.

Historically, the wave theory of light and the particle theory have experienced two wars. The first was represented by Newton, who supported the theory of particles, and Hooke, who supported the theory of particles, and Hooke, who supported the theory of fluctuations, confronted the two, and Newton won an overwhelming victory by virtue of his own identity as a giant of science and the early death of Comrade Hooke. Peace lasted for a century, and the particle theory was absolutely dominant, until the emergence of Thomas Young, the seemingly rock-solid particle theory, was loosened a little, and the second microwave war broke out.

For the first time, both sides were in a state of anxiety. Proponents of the particle theory cannot explain Thomas Young's interference fringes, while proponents of the wave theory also take Marius's polarization phenomenon.

The decisive moment came in 1819, when the French Academy of Sciences held an essay contest with a prize, and Poisson and others, who wanted to raise the profile of the particles, did not expect to be waiting for Fresnel's birth. He changed his previous understanding of light from longitudinal waves to transverse waves, and successfully solved the problem of diffraction of light and the polarization of light that had long plagued the wave theory with rigorous mathematical reasoning. Later, the controversy and verification of the bright spot (Poisson spot) in the center of the disc light point during disc diffraction became the finishing touch. Later, Foucault's test of the speed of light turned out to be the last hope of the particle theory, and he was directly sentenced to death.

After more than a century of struggle, the wave theory finally turned into a serf and sang and occupied the throne of the ruler. Subsequent discoveries, most notably Maxwell's papers on the theory of electromagnetism published in 1856, 1861 and 1865, were an important addition to the theory of particles. He believed that light was just one type of electromagnetic wave, and the only question now was who would prove the truth of his predictions.

Taking advantage of the quarrel between a group of foreigners, Wang Yi pulled Shen Yazhi to his side, and while eating, he told her about the grievances and hatreds between the particle theory and the fluctuation theory.

Although Shen Yatou didn't understand some things, she also understood the general situation, so she no longer felt so incredible about the quarrel of a group of foreigners. In her heart, she felt that such quarrels were much stronger and cleaner than those power struggles in the court.

Scott Williamson, who is the head of the Sean glass experiment project in the Department of Materials, came to Wang Yi's side at this time and said, "Sir, your previous contact with you, and your mention to me, let me know that you are one of the greatest scientists in the world, so let's end this argument and come and hear what you think!" ”

All eyes were on Wang Yi, from a group of foreigners who had come from thousands of miles to China to engage in scientific research, as well as elementary school students who ate in this dining room.

Wang Yi thought for a while, nodded, and for some reason, the entire dining hall suddenly erupted in warm applause. Shen Yazhi, who was originally sitting beside Wang Yitu, felt excited for no reason at this time, and there was a kind of joy and encouragement with honor, and her white and tender little hands were red.

Everyone here knows Wang Yi, because he is not only the principal of the Dashang Affiliated Primary School, but also the supreme controller of the Dashang Industrial Laboratory.

"I'm here today to share with you my thoughts on what light is......"

The alternation of Chinese and English was Wang Yi's limit, and although there were some scholars from Germany and France, there were many people around them who could speak English, German and French, and these people acted as temporary translators.

Someone brought in a large blackboard, and Wang Yi said as he memorized the board.

He started with the history of optics, and then gradually unfolded, the first microwave war, the second microwave war, the language is full of fun, even those first-grade elementary school students who don't understand anything are attracted by Wang Yi's story. And every time Wang Yi talks about a country's celebrities, the country's scholars will unconsciously express a heartfelt pride. Wang Yi understood this feeling, but it was an experience that only existed in later generations. If he does not return to the Qing Dynasty, he will never truly understand how great the country where he once existed is.

"When Maxwell's three papers on the theory of electromagnetism deduced that light is actually just one of the electromagnetic waves, then what we need 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 said what you think!" ”

Everyone else nodded along with them, after all, the debate over the particle theory of light and the wave theory now seems to be like an unsolved case filled with a strange fog, although it seems that the truth is revealed, but who can be sure that this is not the beginning of another puzzle?

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

After speaking, Wang Yi packed up his things and left the dining hall with Shen Yazhi, and the rest of the people were stunned. But then everyone was excited again, it seems that Wang Yi has something important to announce in scientific research!

On the way back to the office, Wang Yi walked leisurely and leisurely. Shen Yatou jumped up and down beside Wang Yi, and after being quiet for a while, she finally couldn't help but ask.

"Headmaster, you are so powerful, you say, is this light fluctuating right? Or is the particle right? ”

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!" Hahaha......"

Shen Yazhi was stunned in place, she never thought that what Wang Yi gave would be such an answer. After thinking about it for a long time, he couldn't understand the mystery, so he finally had to stomp his foot hatefully, looked at Wang Yi, who had already walked away, and hurriedly chased after him. grimaced at Wang Yi's back from time to time, waving his fists, and kept muttering: "If you don't sue sù, you won't sue sù!" Who is rare! ”

can make Shen Yatou angry enough, overall, Wang Yi is still very pleased.

Three days later, in a large real room on the second floor of the electromagnetic real building, the windows around were closed with thick black cloth curtains, and Wang Yi stood at the door, and the corridor outside the real yàn was already crowded with people.

"How's it going?" Later scholars couldn't crowd it out, so they asked questions from time to time.

"Didn't start!"

Zhang Jingxiao was standing outside the crowd at this time, he didn't mean to come to see the truth, he just rushed over because of the matter of Dashang Shipyard, but he didn't expect to encounter such a grand scene. And beside him at this time stood a young student of seventeen or eighteen years old, wearing a small hat inlaid with emerald green jade, wearing a brocade robe, gorgeously dressed, looking quite rich, just the white jade wrench in his hand, it can be called priceless. The appearance is also outstanding, with fair skin, but it looks a little fat.

"Well, what kind of game is this pretending to be a ghost!?"

Zhang Jingxiao frowned, his expression very displeased.

When this person saw it, he immediately changed his expression, "Brother Jingxiao, don't be angry, I won't say it." That being said, he still muttered unconvincedly: "Who are you fooling, these foreign devils are crowded, and they don't smell of sweat." ”

Wang Yi said to everyone at this time: "Everyone, I know everyone's feelings, but the indoor space is limited, so please line up to enter." Turning his face, he said to Shen Yazhi: "Let ten people enter each time!" ”

The girl nodded obediently, she had already finished reading it, and she had watched it more than once. Even so, she couldn't believe what was happening in front of her.

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

Scott and the others, who were originally full of interest, were somewhat deflated after seeing the layout of Wang Yi's real room, which was divided into two pieces by a large black cloth, and this part of the real equipment that can be seen at present can only be described simply.

An electrical spark generator with two small copper balls spaced closely apart as capacitors.

"Everyone, pay attention!" Wang Yi reminded that he closed the power switch at this time.

The magic of electricity was revealed, and an invisible current passed through the induction coil in the device and began to charge the two small copper ball capacitors. After a while, a blue spark flashed between the two copper balls, and the entire system formed a completed loop, and small beams of electricity kept twisting between the copper balls, blooming faintly fluorescent.

At this time, Wang Yi walked to the black cloth separating the real yàn room and pulled it away.

The other half of the real yàn room is even more humble than this one, with only an open copper ring, and a small copper ball inlaid in the opening, without any external power supply.

It's just that except for Wang Yi, everyone present was speechless, because between the two small copper balls of the open copper ring, blue electric sparks were blooming happily.

This is the flower that opened an era! Faraday laid the foundation for it, Maxwell built it, and today Wang Yi has sealed the roof for it. It can be said that from today onwards, the theory of electromagnetism has been truly established!
