Xu Fuyuan and Xia Yunyi were actually more famous scribes in the late Ming Dynasty, and they were also more famous national heroes. Xia Yunyi's name is particularly prosperous, he and Chen Zilong together in the south of the Yangtze River to resist the Qing Dynasty, after the defeat left the famous desperate poem suicide martyrdom, the name of the martyr is even above Chen Zilong, which is recorded in the history of the Ming Dynasty.

It stands to reason that these two talented, loyal and patriotic people should be big officials in the late Ming Dynasty or the Southern Ming Dynasty, and they should occupy a lot of space in the history, why do they seem to be not famous at all?

also blame them for their bad luck, at that time in the Chongzhen Dynasty, that is, when they participated in the imperial examination, it was when Wen Tiren and Zhou Yanru, the two traitorous ministers, were in power, and the imperial examination completely became a tool to eliminate dissidents and form parties for personal gain.

For example, Xia Yunyi, Wanli forty-six years (AD 1618) on high school lifting, until Chongzhen ten years (AD 1637) to enter the Shi and the first, Xu Fu is far more than him, because the background behind the famous family has been suppressed, and it was not until the fifteenth year of Chongzhen (AD 1642) that he was admitted to the lifting of people, and Chongzhen hung up two years later, the world was in chaos, and he didn't even have the opportunity to be named on the gold list!

These two people in the Chongzhen Dynasty is fate to the extreme, in the Chongzheng Dynasty is lucky to the extreme, they learned from Xu Guangqi from the knowledge of Western learning was not very useful, but it coincided with our Chongzheng Emperor to open a science and select science talents, so the background of Western learning made them make a simple logical algebra problem, and at the same time sat on the rocket of promotion.

The day after the palace examination, the holy decree arrived, Xu Fuyuan and Xia Yunyi were promoted to the Ministry of Industry at the same time, from the third rank, although not as powerful as the left and right servants of the Ministry of Industry, but they were already fake three-rank officials, and they could enter the ranks of high-ranking officials in the Ming Dynasty.

Why did Zhu Cijiong give them a fictitious title with no real power? This is mainly for the convenience of the professor, if they are assigned a real job, they have to go to class, and there is less time to study, this electromagnetism is a real 'book of heaven' for the people of the Ming Dynasty, and they can't learn to listen to lectures after work, and they must study with all their strength to be expected to learn, so Zhu Cijiong did not arrange anything for them, and the only thing they have to do now is to concentrate on learning electromagnetism.

In other words, how was this 'heavenly book'-like electromagnetism taught in the Ming Dynasty? Nowadays, the reason why people can quickly accept the knowledge of electromagnetism is because the application of electromagnetism has been very extensive, electric lights, televisions, computers, telephones, etc., electricity is everywhere, and it can be seen every day, so it is naturally easy to accept.

In the Ming Dynasty, there was nothing to be electric, and the only chance to contact electricity was the terrifying thunder and lightning on a rainy day, and the rumbling thunderclouds could scare people's souls out, who had nothing to do to study that thing!

In order to teach Xu Fuyuan and Xia Yunyi the knowledge of electromagnetism, Zhu Cijiong tried his best to prepare a detailed teaching plan.

If you want to teach people electromagnetism, you must first expose them to electricity, just like learning to write, first of all, you have to see the words, you don't see the words, how can you learn to write?

Electricity is not difficult to see, of course, what is said here is not to let people run outside on a rainy day to see thunder and lightning, in fact, a small experiment can make people see electricity.

Chongzheng Emperor Zhu Cijiong's first experimental class was carried out in his private study, Xu Fuyuan and Xia Yunyi were extremely nervous at this time, saying that the emperor inexplicably mentioned to them from the three products, but did not arrange work for them, which inevitably made people feel worried, and now the emperor finally invited them to come to the audience, not nervous It is fake.

However, there was still no work, the emperor just asked them to stand there and watch what experiments!

What does 'experiment' mean, Xu Guangqi, Bi Maokang, and their old cronies are naturally familiar and can't be more familiar, but Xu Fuyuan and Xia Yunyi, the two newcomers, are confused, they just stood there dumbfounded, looking at them stupidly.

First of all, the two little eunuchs carried the thick blankets on their backs and carefully folded them on the table. What does this mean? Do you need to put a blanket on the table either on the bed or on the floor? Maybe there are more valuable things to take out next, and putting a blanket is afraid of breaking it, Xu Fuyuan and Xia Yunyi both think so.

However, there were no valuable things to appear, and what the emperor wanted them to look at seemed to be blankets, and it was not normal to see, because the emperor directly ordered a few eunuchs to block the windows with thick quilts, and the whole study was suddenly dark.

At this time, the emperor spoke: "Fuzhai, Yi Zhong, you two look carefully, Cao Huachun, you can start." ”

Xu Fuyuan and Xia Yunyi suddenly had an urge to burst into tears, this difficulty was a bit beyond their imagination, how do you look at the black pitch? Why don't you light a lamp!

Of course, Zhu Cijiong won't light the lamp for them, and if they light the lamp, they can't see it!

As soon as he gave the order, the two little eunuchs immediately began to pull the two blankets in the opposite direction, 'Woo la, Woo la', a faint sound sounded, and a tiny arc of electricity appeared between the two blankets.

Xu Fuyuan and Xia Yunyi looked at all this in amazement, this seems, as if they had seen it somewhere, but the small flashes were not so dense.

The two little eunuchs dragged the two blankets repeatedly, and the sound of 'lala, lala' in the study kept ringing, and then Zhu Cijiong spoke again: "How is it?" Fu Zhai, Yi Zhong, have you ever seen this phenomenon? ”

Although it was in the dark, Xu Fuyuan still bowed his hand respectfully: "If you go back to the emperor, Weichen has seen it, like wearing a little more in winter, and occasionally seeing it when you take off your clothes and go to bed at night." ”

Xia Yunyi then said respectfully: "If you go back to the emperor, Weichen has also seen it, and I also saw it when I took off my clothes at night in the winter, but this thing doesn't seem to be touchable, it's a little numb." ”

They both admired the two little eunuchs a little, the feeling of the hemp man was not comfortable, these two little eunuchs actually endured it all the time, and they didn't make a sound at all.

When Zhu Cijiong heard this, he immediately clapped his hands and said, "It's good to see it, Cao Huachun, remove the curtains." ”

Soon, the quilt covered by the window was taken off, Xu Fuyuan and Xia Yunyi were still staring at the blanket, and then they saw that the two little eunuchs were holding two thick wooden clips in their hands, and they didn't directly grasp the blanket with their hands, no wonder they didn't make a sound at all, and they didn't touch the blanket at all for a long time.

Of course, Zhu Cijiong knew that static electricity numb, it was uncomfortable to be electrocuted, he naturally would not let the little eunuch directly touch it with his hands, and the experiment did not end there, he also needed that static electricity to be kept on the blanket, as soon as the person touched it, the static electricity was gone.

When the study was bright, Zhu Cijiong immediately walked to the blanket in person, took out a plush glove and put it on his hand, and then beckoned: "Fu Zhai, Yi Zhong, come here, watch carefully." ”

Hearing this, Xu Fuyuan and Xia Yunyi had no choice but to step forward respectfully and stare closely at the gloves on Zhu Cijiong's hand.

Zhu Cijiong slowly put the back of his hand close to the blanket, and a magical scene appeared, as the distance approached, the fluff on the glove exploded directly, and the back of Zhu Cijiong's hand was like a hedgehog.

Zhu Cijiong ordered again: "Fu Zhai, Yi Zhong, you all put your hands close to the blanket, just like me, just get close, don't touch it." ”

Xu Fuyuan and Xia Yunyi immediately leaned over slowly with curiosity, and the two of them obviously felt that the hairs on their hands were also standing up, they really hadn't tried this, what was going on?

Zhu Cijiong didn't open his mouth to explain, but asked, "Do you know what is on this blanket?" ”

Xu Fuyuan and Xia Yunyi both pondered, and they didn't reply for half a salary, and Zhu Cijiong had to guide: "It's all bold guesses, it doesn't matter if you're wrong." “

Xu Fuyuan had actually guessed a long time ago, and only then did he say cautiously: "Weichen dared to guess that the thing on this blanket is a bit like thunder and lightning, very small thunder and lightning. ”

Zhu Cijiong's eyes lit up when he heard this, he dared to think that he was a genius, he was definitely a genius in physics! He couldn't help nodding his head and approving: "Fu Zhai is very right, this is thunder and lightning, and the thunder and lightning in the sky are also produced in this way, but it is produced by the friction between two very large clouds, and the clouds are at least a few miles or even dozens of miles in a radius, so the thunder and lightning produced are very large, so big that they are several miles or even dozens of miles long." ”

If this is said in modern times, it is naturally nothing, everyone knows that this is the case, but it is a bit shocking to say it in the Ming Dynasty, and it can be superstitious at that time, everyone thinks that the thunder and lightning in the sky are released by the thunder male and the electric mother.

Looking at everyone's shocked expressions, Zhu Cijiong couldn't help but touch his head and said embarrassedly: "Hehe, the two clouds that rubbed against each other should have been dragged by Lei Gong and Dianmu, how could mortals go to the sky to drag that thing?" ”

Well, this lie is more in line with the mythological background at the time, and everyone suddenly realized it, looking at Zhu Cijiong with reverence, the emperor is amazing, even Lei Gong and Dianmu know how to release thunder and lightning!

For the people of the Ming Dynasty, of course, Zhu Cijiong is powerful, you must know that the history of human discovery and application of electricity is not done in one or two experiments, the laws of physics and chemistry are verified from countless experiments, in order to discover and prove the existence of electricity, countless scientists have studied it for decades. Like the scientist Benjamin Franklin a hundred years later, in order to prove that lightning in the sky is the same thing as electricity on the ground, he once flew a kite in a rainstorm like a madman!

Xu Fuyuan and Xia Yunyi are much luckier than them, they don't have to think about it for decades, and they don't have to fly kites in the rainstorm like crazy people, Zhu Cijiong will tell them through experiments one by one, what are the characteristics of electricity, and what are the basic laws of electromagnetism.

The famous scientist Isaac Newton once said, "I see far because I stand on the shoulders of giants." ”

The giants that Newton said refer to Copernicus, Cavendish and Galileo and other scientific pioneers, and our Chongzheng Emperor Zhu Cijiong was also a giant for these people in the Ming Dynasty, a 'scientific giant' who has seen the results of scientific and technological development hundreds of years later, Xu Fuyuan and Xia Yunyi are destined to stand higher and see farther!
