At the beginning of the civil castle, the Ming God of War was a little panicked

Chapter 388 This is Science

A miracle happened, that hair moved again!

As if there was life, I leaned on it.

Tong Xuan's expression was both surprised and joyful, and he hurriedly asked: "This humble minister is ignorant, I implore the emperor to clear up my doubts!"

Zhu Qizhen pointed to the chair beside him and said, "Sit down and talk, Belin, you sit too."

But Tong Xuan didn't dare, waved his hands again and again, and said: "I'd better stand and listen!"

Belin said: "The emperor asked you to sit, but you sit, how do you record it while standing?"

Tong Xuan came to his senses and hurriedly pulled two chairs over, gave one to Beilen and sat on one himself, and at the same time took out the pen and paper for recording.

Zhu Qizhen thought for a while, and then said: "Electricity is both matter and energy. In fact, matter and energy are one concept, but two different forms of expression."

Tong Xuan quickly recorded, but his brows became more and more wrinkled, almost twisted into a twist.

Not only that, Belin's face was also ugly.

As the dean of the Daming Academy of Sciences, he... can't understand it at all!

matter and energy?
What the hell!

Looking at the expressions of the two, Zhu Qizhen could roughly understand their mood.

"Look out the window, what's that?"

Tong Xuan and Bei Lin looked up at the same time, and said at the same time: "The sun!"

"Why does the sky light up when the sun rises?"

"Because...the sun shines?"

"That's right!"

Zhu Qizhen nodded and said, "What is light?"

"Just...is..."

The two fell into deep thought again, yes, what is it?

Zhu Qizhen knew that they didn't understand, but at this moment, he had no choice but to forcefully indoctrinate him.

"It's just a kind of energy. Plants absorb this energy, and then cooperate with the carbon dioxide in the air, as well as the water and nutrients absorbed from the ground, so that they can grow bigger, grow taller, and bloom and bear fruit. Do you understand this? ?”

Beilin and Tong Xuan looked at each other, seeming to understand, but also seeming not to understand.

Zhu Qizhen ignored them and continued: "This process is called photosynthesis, which is the process of converting energy into matter. Therefore, the essence of matter and energy is the same."

The two looked at each other again, as if they were listening to a scripture.

Belin sighed secretly in her heart. After so many years of scientific research, it seems that she has not even seen the threshold...

Zhu Qizhen couldn't explain it in depth, so he had to say: "I won't discuss the matter and energy in depth. Today I mainly talk about electricity. In fact, electricity itself exists, and it only manifests in rainy weather."

He took the pen and paper from Tong Xuan and wrote down the plus and minus signs.

"What we usually call electricity is composed of charges. There are two basic types of charges. This symbol is called positive charge, and the corresponding negative charge. You can also understand it as yin and yang. These two kinds of charges interact with each other. Attraction, at this time, we will not notice the existence of electric charge at all, but when it rains..."

While talking, he drew two more clouds on the paper.

"In simple terms, on this cloud, the positive and negative charges will separate, one end will be positively charged, and the other end will be negatively charged. At this time, we still cannot observe it until the two clouds collide!"

Zhu Qizhen put down the pen, stretched out two fists, and touched them together.

"As I said just now, positive charges and negative charges attract each other, and two clouds of different charges collide and will be annihilated quickly. In this process, lightning and thunder are produced. Since the speed of light is faster than the speed of sound, we are all See the lightning before you hear the thunder."

Tong Xuan tried his best to digest these words, as if a door to a new world had been opened, but behind the door was not unimpeded, but dark.

Because he...can't understand!

Beilin's expression was similar to Tong Xuan's, as if she understood, but also as if she didn't understand.

Seeing that neither of them spoke, Zhu Qizhen had no choice but to say: "I didn't understand what I said just now, you should ask!"

Belin wanted to say that he didn't understand anything, but he didn't have the courage.

But Tong Xuan said: "The emperor just said... Yin and Yang will attract each other, why are they separated in the cloud?"

"very good!"

Zhu Qizhen praised: "Being able to ask this question shows that you have listened. However, this question is more complicated to explain. You should do the most basic knowledge first."

"My minister...obey the order!"

Tong Xuan felt deeply ashamed, remembering how ignorant and fearless he was back then...

Zhu Qizhen picked up the pen again, this time, he drew a picture seriously.

Tong Xuan and Bei Lin watched from the side, it seemed that there were many coils, and there was a stick in the middle.

At this moment, Tong Xuan looked at the stick in his hand and fell into deep thought again.

Could it be that an ordinary stick is the key to the development of electrical research?

"Don't look, this is a magnet!"

Zhu Qizhen clicked the "stick" on the picture, and said: "According to the sketch I drew, prepare a copper coil and a magnet. Remember, the coil must be insulated...well...wrapped with cotton yarn, remember to remember , the copper wires must not have contact with each other."

Tong Xuan nodded repeatedly, waiting for the next instruction.

Zhu Qizhen asked: "Do you understand?"

"I understand, but... I don't really understand..."

Tong Xuan's answer was very objective and sincere, and he really didn't understand.

"It doesn't matter if you don't understand now, first prepare according to what I said, and you will gradually understand."

"Yes!"

Zhu Qizhen's painting is the simplest electromagnetic induction device. By turning the magnet, the magnetic field and the coil cut each other to generate an electric current.

However, how to verify such a current has become a new problem.

After much deliberation, it is more straightforward to use lighting.

"Beilen, go and prepare it. Use bamboo shreds to burn charcoal. Prepare more, about the length of your thumb, the thinner the better."

"Yes!"

I vaguely remember that before Edison discovered the tungsten electric lamp, he tried to use carbonized bamboo wire, and the effect was not bad.

With Daming's current level of technology, tungsten wire is a bit difficult, but carbonized bamboo wire is still possible.

In the next few days, Zhu Qizhen simply refused to approve the report, and devoted himself to the power research and development team.

Belin also temporarily put aside the work of the Academy of Sciences to fully assist in the electric power experiment.

After the continuous attempts of the monarch and his subjects, finally, the pitch-black carbonized bamboo thread... lit up!
Although it only lasted for a short time, it was a success!

Tong Xuan was going crazy, he finally opened the door to the world of electricity.

Although this door was opened by the emperor, but... still very excited!

"Your Majesty, what is the reason for this?"

Tong Xuan was so excited, the experiment was successful, a copper wire and a magnet really created electricity!
He couldn't wait to know the principle, because it was too important for follow-up research.

Zhu Qizhen also showed a knowing smile and said, "This is science!"
