When Zhu Di's edict reached the Forbidden City.
Basically, all the officials understood one thing.
This Country Supervisor had already taken over the authority of the Son of Heaven!
Not only did he have the power to govern the country!
Even the relatives of the emperor had to listen to the king.
It was no longer just a country!
Everyone saw that the country supervisor was still like his father!
Zhu Zhanxin, who received Zhu Di's affirmation, was even more relaxed.
Winter was already halfway through.
Natural Science Garden.
Zhu Zhanxin took some time to come to Gewu Garden today.
He planned to give the 20-odd students a lively physics lesson.
Seeing that the governor had arrived.
The students of the Natural Science Garden put down the books in their hands and stood up to salute.
Zhu Zhan looked at them and said,"No need. Have you seen the things I sent over?" Is there anyone who knows how to do it?"
A student stood up and bowed. He shook his head and said," Although it's called 'small hole imaging' and there are books about it, we are all muddle-headed. We don't understand the key nodes of some of the operations at all. We can clearly get results every time, but we fail at the key places, resulting in unsatisfactory results.”
"Is that so? How's your triangular prism recently?”
"Thanks to the good fortune of the country's overseer, the craftsmen have already made it for us. We have also studied the magnifying glass for a few days. We can already complete the ignition under the sun according to some simple theories in the book. We also placed the triangular prism into water and decomposed it into the seven colors of the rainbow.”A student stood up and said. The joy on his face was visible to the naked eye.
It could be seen that they were very interested in the subjects in the Natural Science Park.
Zhu Zhan Xin saw this and felt very gratified in his heart.
It seemed that these students were right.
Zhu Zhanxin walked to the lecturer's desk in front of him. On it was the experimental equipment for small hole imaging sent by the craftsman. They were all made according to the drawings given by Zhu Zhanxin.
"Come, everyone, gather around. I'll teach you step by step.”
"What? Thank you for supervising the country!"
"Thank you, Country Supervisor!"
"Come quickly, it's time to watch the Imperial Supervisor's experiment!”
Zhu Zhan looked at the students who were interested in mathematics and physics, and he planned to teach them well. They were all smart people.
All of them were the top students of the Great Ming Dynasty, and they were even filled with passionate interest in these "exotic and licentious skills" in the eyes of others.
He had to teach them about mathematics, physics, and chemistry.
Cultivate Da Ming's talents!
He began the experiment of the small hole imaging.
As Zhu Zhanxin operated, he explained to the students who surrounded him,"A thousand years ago, among the Hundred Schools of Philosophy, Mozi and his disciples discovered the principle of small hole imaging, so this experiment is the best way to get started.”
A student replied,"Is supervising the country recorded in the ten miles of the Mozi?" That person's reflection, the reflection behind the hole."
"Yes." Zhu Zhanshi continued," The specific experiment, you see here, is to use a small plate with a small hole to block it. Move it between the small wall we erected and the object. Here, a candle will form a light source. When it shines over, the light will scatter. Look at the reflection on the wall here.”
It was just as Zhu Zhanxin had said.
The small reflection appeared on the small wall made of black wood.
For a moment, the students here had a sense of excitement in their eyes as if they had seen something "magical".
Zhu Zhan Xin was very satisfied with the expressions in their eyes.
This was actually an instinctive thirst for knowledge.
One had to have a thirst for knowledge in order to obtain natural science.
Immediately after, Zhu Zhanxin began to move the small hole's board. Just like that, he moved the middle board back and forth. Following that, the size of the object on the wall gradually changed, and even the brightness gradually changed.
The surrounding students of the Natural Science Park all had expressions of realization on their faces.
Zhu Zhan saw this and said,"Light travels in a straight line in the same uniform material!" As you can see, the closer the object is, the bigger and dimmer the image will be! The farther the object was, the smaller the image was, and the brighter it was.”
"State Supervisor, I understand!" One of the students was overjoyed and said,"This is, when the scene arrives, there is an end at noon, and when the scene grows, there is an end!”
Zhu Zhanxin nodded and smiled.”
"Disciples understand!"
"Thank you, Supervisor."
"Supervisor, I understand."
"Thank you for your guidance, Imperial Supervisor."
These outstanding students all bowed towards Zhu Zhan Xin with faces full of admiration.
Every student's eyes were filled with incomparable reverence!
At this moment, in their eyes, the country supervisor was still a teacher who taught and dispelled doubts.
He even knew a lot of knowledge that could make them exclaim in amazement.
He was comparable to a sage!
Zhu Zhanmo had underestimated the Dao imparting in this era.
Seeing how respectful they were, he couldn't help but become a little solemn!
They were treating him as a respected teacher!
That was good too.
This way, he could continue to teach them more knowledge.
"Come, since you know how to put the prism in water to decompose the seven primary colors of light, let's go deeper. I'll teach you something that the book didn't mention.”
"Yes, sir!"
"Alright, Country Supervisor."
All the students cheered.
At this moment, what Zhu Zhanxin did not notice was that an official was secretly watching not far away.
It was Yu Qian, who had come to find Zhu Zhan.
But at this time, he didn't disturb Zhu Zhanxin who was teaching.
Instead, he quietly came over to listen.
"The country supervisor is really a god!"
Yu Qian was also fascinated by the story and could not help but praise softly.
Just as Zhu Zhanxin was doing the spectral experiment.
Yu Qian also walked over and hid behind the students.
This time, Zhu Zhan Xin did not simply use water to do a spectral experiment.
Instead, he used a few complicated mirrors and found the best position for sunlight. He did a Newton's light splitting experiment and separated the light into different colors.
The colors fell onto the white paper.
" In the end, the light is a single color, so we can't break it down anymore. We have to record this different color. Actually, light isn't colorless. It still has color, just like the rainbow you see. And now, this piece of white paper is the spectrum that we have obtained.”Zhu Zhanxin explained while doing the experiment.
"To be able to hold the rainbow in the sky in his hands, could the country supervisor be an immortal that descended from the heavens?”A student couldn't help but whisper to the student beside him.
"Shh! Won't we know if he's a god or not after we learn it?”
