At this time, Sun Yuanhua said: "Your Majesty, the Instrument Department of the Institute ordered a batch of copper wires here last time.
I heard that they are studying something called electricity and want to turn what Your Majesty said into reality.
I don't know.
Your Majesty, would you be interested in taking a look?"
Zhu Youxiao was surprised and said: "Why didn't they tell me that I was talking about some purely theoretical things?
I haven't figured out how to turn it into reality."
This statement is actually quite telling.
Zhu Youxiao opened a new course on electricity in the graduate school.
This lesson is not easy to teach at all because there are no real objects.
So Zhu Youxiao used a cramming method to explain to them the principle of cutting magnetic lines to produce electricity, electricity can light up lamps, and electricity can make motors rotate.
He felt that it would be difficult to create electricity based on his current level, so he never thought about researching electrical items.
At that time, he just wanted to explain some principles in the lectures and see if they have any guiding significance later.
Zhu Youxiao couldn't even imagine that such a little bit of knowledge could allow them to create electrical equipment.
He excitedly rushed to the Instrument Department of the institute with Sun Yuanhua and others, wanting to see what they had created.
Several students were experimenting.
One student turned the handle to make a magnet rotate around a coil in the middle.
The coil is connected to two wires and is connected to another coil.
The magnet outside this coil is fixed and the coil inside rotates.
Seeing the emperor come in, the students bowed and saluted, and called him "Your Majesty" together.
Zhu Youxiao waved his hand and looked at the device carefully.
The handle the student turns is covered with magnets, while the coil in the middle is stationary.
The coil on the other side is connected to copper wires with a structure like two tiles, and is spinning continuously.
Zhu Youxiao said: "Who is responsible for this?"
A student in his twenties came forward and said: "Your Majesty, this is student Chen Daoyong.
Your Majesty said that metal wires can cut magnetic lines to produce lightning-like electricity.
The students wanted to try it, and as expected they created a device that can move people.
Paralyzing electricity.
The students were deeply inspired and thought of what His Majesty said about electricity being able to make metal rotate in a magnetic field, so they made this device, and it actually started to rotate.
Your Majesty is truly a god."
Zhu Youxiao looked at the side and saw that there was only half of the structure, so he asked: "This is the discharger you developed."
Chen Daoyong said: "Your Majesty, it is exactly this thing.
The faster it spins, the more severe the numbness will be."
Zhu Youxiao thought to himself that the discovery of electric shock seemed to be more than a hundred years later, and the real application of electricity was more than two hundred years later.
If it were to start studying electricity now, would it be too early, because science has not yet There cannot be a big leap forward in one aspect.
It needs the support of science and technology in other aspects.
But if electricity can be truly used, Ming Dynasty will be more than two hundred years ahead of the world.
By then, who will think that science has appeared in the West?
He looked at Chen Daoyong and said: "You gather classmates who are interested in electricity in the research institute to form the Daming Electrical Research Institute.
You are the director.
I will give you more detailed information, sufficient funds and manpower, and everything related to electricity.
All phenomena can be studied.
I believe you will definitely give me a surprise. " Chen Daoyong was shocked.
He was only twenty-four years old, and it was simply unimaginable that he was entrusted with such an important task by His Majesty.
But he replied without hesitation: "The students will not disappoint His Majesty."
Zhu Youxiao asked the students to go to Bi Maokang, the dean of the institute, and inform him about the establishment of the Daming Electrical Research Institute.

The Ming Electrical Research Institute will still be located within the institute, but the funds will be provided by the Ming Royal Science Foundation, so it will not be under the jurisdiction of the institute.
Chen Daoyong and others are graduate school students.
Now that they want to leave the graduate school, they must inform Dean Bi Maokang because of emotions and reasons.
After returning to the palace, he asked a secretary to serve as an edict and began to recall the scientific knowledge in high school.
Voltage, also called potential difference, is a physical quantity that measures the energy difference produced by a unit charge in an electrostatic field due to different potentials.
However, I forgot how to measure halo when the electric potential is different, or the teacher never taught it before.
Only then did Zhu Youxiao realize that he had forgotten a lot of high school knowledge, which was unacceptable.
So for many days, a large number of Hanlin bachelors were summoned to Yuntai and began a campaign to rescue the knowledge in Zhu Youxiao's mind.
Zhu Youxiao wrote down all the knowledge he could remember on all subjects except modern history, regardless of whether it was useful or not.
Therefore, it often happens that Hanlin scholars still do not understand the meaning of the sentence after writing it on paper.
After using it intermittently for more than thirty days, Zhu Youxiao felt that he had been hollowed out, so he stopped, then classified and organized the knowledge, and ordered Wang Chengen to print three thousand volumes and put them in libraries everywhere.
Register and then sent to the institute.
Some of this knowledge was already taught by Zhu Youxiao when he was a professor of six subjects, but it was not as systematic as it is now.
The books are divided into five categories: arithmetic, inquiry, biology, chemistry, and geography.
For graduate students, it is very instructive and inspiring knowledge.
The grid includes mechanics, electromagnetism, optics, acoustics, and heat.
In the book, Zhu Youxiao throws out a large number of unproven hypotheses, such as the three laws of mechanics, electromagnetic theory, the three laws of thermodynamics, and even Einstein's mass-energy equation.
What we learn in high school are all theories.
As for how to verify them, we can only let the students do it.
After Chen Daoyong and the others got the book of investigations, they saw all the unfamiliar terms: voltage, electricity, current, resistance, and capacitors, all of which were huge.
Finally, Zhu Youxiao compiled another booklet, listing some basic experimental precautions in electricity.
For example, wires should be covered with insulators.
Magnets or coils can be rotated using water, but exposed wires should not be touched by others.
The wires can be tested on animals.
Otherwise, I am afraid that a few students will be electrocuted to death as soon as the experiment begins.
Therefore, the Daming Electrical Research Institute began their research under the guidance of extremely advanced theories and extremely simple experimental conditions.
The money provided by the Royal Science Foundation was sufficient, but there was nothing to buy.
Just like the most common insulated wires, the copper wire can only be wrapped with wood chips or thick cotton.
But when these students suddenly saw such a colorful new world in front of them, they were extremely excited and vowed to study electricity thoroughly so that electricity could be used by the people of the Ming Dynasty
