Ji Tang

Chapter 446 Ice Making
"Is it funny?"

Ji Song looked at the audience, these students who have reached a height that others cannot reach in their lifetime.

Soon the classroom became quiet because everyone saw that Ji Song's face looked very ugly.

People who don't know or are not familiar with Ji Song also know how powerful he is after he can make Li Tai, a man who even the prince dared not stab, surrender.

Everyone else who knows Ji Song knows that as long as he shows this expression, it means that he is very unhappy, and the consequence of being unhappy is to be punished.

They winced at the thought, hoping Ji Song didn't see them.

"Originally, I was very unhappy that the academy brought you all together and asked me to teach!"

"The academy is a fair place. Why do you guys want the academy to accommodate you? If you don't study hard or don't want to learn, get out of here immediately!"

"The academy is a place for teaching and educating people. Other poor students are working hard to absorb the knowledge from books and teachers, but you are constantly wasting the few resources of the academy. This is very unfair!"

Ji Song spoke very loudly, and Li Tai showed disdain, not for Ji Song, but for other students.

Cheng Chusi didn't care, since he was already disappointed with himself, so he could do whatever he wanted. He would go to the army after graduation.

There are also many special students who look pensive towards Ji Song's attitude.

"Don't think that if you think your knowledge exceeds theirs now, you will definitely surpass them in the future. The most unreliable thing in the world is your own self-confidence."

"Other students are not as good as you because they did not receive the treatment you did when they were young, and they did not have any great Confucian masters to teach them. Many of them learned by themselves with the help of one or two books."

"But now hehe!"

Ji Song sneered, now?Now they have the best academy and the best teachers in the world, as well as countless book resources.

As long as he completes his foundation and adds his perseverance and hard work to the end of his studies, it won't be long before he can surpass these pampered people with ease.

"Okay, let's continue to class!"

He did not dwell on this issue anymore, because it was meaningless. Only people who have suffered big losses will be alert.

"The course of studying things is to ask more about why, dare to say what others dare not say, and think what others dare not think. Only in this way can you form your own system. Remember, this is very important!" Ji Song warned! .

There are too many people in this world who study hard and read a lot of books, but they never get out of the circle of their predecessors, always wandering in it, and some even become stupid in reading.

Reading too many books is not necessarily a good thing. Some people can rule the world by reading a copy of "The Analects of Confucius", and some people can innovate by reading only a few books, and even draw inferences from one example.

But there are also people who have read a lot of books, but the more they read, the more stupid they become. They have even lost their basic ability to distinguish, and they can only follow the crowd and follow what others say.

Next, he focused on introducing what kind of subject Gewu is and how to learn it.

He mixed a lot of private goods into it, and based on the predecessors, he guided the investigation to a more realistic place.

The theories of the sages are of great reference value, but they are basically a disorganized discussion. Everyone has their own understanding, which makes people at a loss as to what to do!

It looks very high-end and very powerful, but when it is used in reality, it seems very blank and makes people unable to start.

Therefore, he incorporated the physical systems of later generations into it.

Since it is impossible to comprehend it from a macro perspective, let’s start from the reality, from what we see and hear in our daily life.

The "Tao" spoken by the sages is very mysterious, and the "reason" spoken by the sages is very empty.

Then start with small things now, as small as why you breathe!
Li Ke was very serious. He seemed to see a different world from his brother-in-law's words, a world where everything knew its origin.

It's not as mysterious as the books say, nor is it that difficult to understand.

He is all around us, in everything we see, he seems not to exist, and yet he seems to be omnipresent.It turns out that everything we see can be viewed with the perspective of investigating things. It turns out that he is in every move we make.

In order to let everyone realize the charm of gewu more intuitively, he asked Li Tai to take a few students to the miscellaneous office to pick up some things.

Li Tai had a look of displeasure on his face, and he knew how to order me, hum!
Not long after, Li Tai brought the empty basin, and others also brought the remaining things!
"Come on, everyone, come outside. Today I want to show you the application and magic of gewu!"

Soon everyone came outside. It was almost midday, and the power of the autumn tiger was still very bluffing.

"Fill the big basin with water, and then pour the saltpeter into the water. Li Tai, go get some water from the small basin!"

"Why me again?" Li Tai said aggrievedly.

Ji Song had no intention of breaking up with him. He glanced at him sideways and said, "Are you going?"

Li Tai thought for a long time, then held his breath and went to fetch water.

"Put it on top of the big basin."

After finishing this, Ji Song didn't say anything. Everyone, look at me and I look at you. I wonder what you are doing?
But soon some attentive students discovered something unusual about the water in the small basin above. Was it steaming?
"This is?"

Li Ke stepped forward and tried it with his hands, but quickly pulled back and looked at Ji Song in shock: "Why is it cold?"

"What's cold? Can I not know the water I'm getting?"

Li Tai was very surprised. He had washed his hands just now, and they were a little cold. He couldn't say they were cold at all!

He didn't believe it, so he stepped forward and put his hand into the small basin.

"Xiao Tai."

"Ah, it's so cold!"

But before he could finish speaking, Li Tai quickly retracted his hand and kept pinching it. His hand was already a little red.

"How is this possible?" He looked at Ji Song in disbelief, wanting an explanation.

Why does water get cold on a hot day?

"Look, the water is freezing."

Only then did everyone realize that the water in the small basin had begun to turn into ice. They all knew that water turned into ice, but this was the first time they had seen the process of water turning into ice so intuitively.

But it’s early autumn now, when I’m sweating just after standing for a while!

Soon, all the water in the small basin turned to ice, and there was a slight chill.

Everyone made a sound of inhaling. Is this a magic trick?
Then he shook his head, some people had discovered some problems.

"Is it saltpeter?"

Li Ke looked at Ji Song in confusion, and Li Tai also said loudly: "Did the saltpeter make the temperature drop?"

One of them, a young man who looked small but had a burly figure, also came out and said, "Why does saltpeter make the temperature of the water lower?"

At this time, other people also reacted. The water was just ordinary water, and there was nothing wrong with the basin. If it weren't for the magic trick, the only problem would be the saltpeter.

It was saltpeter that turned water into ice, but why?This was a bit overwhelming for their poor brains.
