Strictly speaking, Xiao Han is not very good at lecturing.

At most, that is, in Zhuangzi, he talked to the children about arithmetic.

Occasionally, if you are in the mood, you will have kung fu, and you will just take a few more natural science classes.

is such a charlatan who can only fool the third grade at most, and meet the fourth grade is mysterious enough.

In today's Faculty of Science, it can also make the people in the auditorium dumbfounded, can't you say that it should be proud? Or is it sad?

appeased the teary-eyed little fat man, and then, Xiao Han did a few classic experiments in later generations.

The content of the experiment is nothing more than a candle burning in the water, or a piece of paper covering the mouth of the cup to keep the water from flowing down.

The most difficult part was the last small hole imaging experiment made with a wooden box and window paper.

It's also funny, the experiment of small hole imaging was first created by Mozi, and now it is Xiao Han who is standing on the podium to explain the principle.

This made the Mo family in the audience, especially Yin Can, blush.

We talk about inheritance every day, but how many are really inherited?

At the beginning, the Mohists paid attention to the study of epistemology, logic, geometry, geometric optics, statics and other disciplines, but unfortunately all of them were almost lost later!

Of course, in the same way, the original core idea of Confucianism, the unity of knowledge and action, is also lost in the smoke and dust of history.

Some people say that this is the general trend! It is because of the existence of such a creature as the emperor in the world, so that all schools of thought have to grovel to please the emperor.

Among them, some knowledge that does not bring them any benefit, and may even bring disaster, will naturally be discarded.

But Xiao Han didn't think so.

Knowledge, really fancy the environment! But before the explosion of knowledge in later generations, the whole world was not much better than today's Datang.

Perhaps, it just lacks a seed, a seed that allows people to work in this direction.

Therefore, the establishment of the academy can be said to be a fertile soil that Xiao Han inadvertently cultivated.

Today's lecture has planted a seed of hope in this land.

A unique course has given those students who are accustomed to hearing the word "learning" a new understanding of the word "learning", and it has also opened a door to a new world for them.

It turns out that the truth is not those big and empty things, and there is truth around you all the time and everywhere!

If you can discover it, master it, and even take advantage of it, then it will bring unexpected surprises to everyone.

"Reading, not letting you die reading! To be able to obtain truth through reading, so as to benefit oneself, one's family, and even one party and one country, this is the real reader! ”

Although a day has passed, the little fat man Wang Chong'an's mind still echoes the words Xiao Han said,

After a morning of class in a trance, Wang Chongan gritted his teeth and caught up with Mr. Song, who had already left the classroom.

"Sir? Can reading really be the same as the court judged? But the truth we learned before was just how to be a gentleman, as if we couldn't do anything other than that......"

In the corridor outside the classroom, Wang Chongan caught up with Mr. Song and respectfully asked for advice with his disciples.

Mr. Song, who was holding the lesson plan, stopped when he heard the sound, looked back at the little fat man with a tangled face, and couldn't help laughing: "Hehe, I saw that you were wrong when I was in class just now, so I was really thinking about this!" Yes, it looks like you listened very seriously yesterday! ”

Wang Chongan scratched his head and said embarrassedly: "Sir, have you forgotten?" I was right next to the judge, and his spitting stars were spraying me, could I hear clearly? It's just that there are some things he said that I don't understand. ”

Mr. Song was stunned when he heard this, and then laughed: "Oh? Hahahaha, I almost forgot, you were on stage at the time! ”

Wang Chongan was even more embarrassed by the old gentleman's laughter, twisted the corners of his clothes, and said with a red face: "Hey, sir, don't care where I am!" I understand that the truth he said yesterday comes from all things in the world, but I don't understand that the truth he said can be applied to all things! Like you taught me before, a gentleman should clean himself, this is the truth, right? How can it be used? ”

Listening to the little fat man talk about learning, Mr. Song slowly lost his smile, stood up straight and thought about it, and said, "How to use it?" The old man can't teach you this, because the old man can't either! But the old man has one thing to tell you, there are many kinds of truths, and not all of them can be used with what the court judges! ”

The little fat man nodded as if he didn't understand, and asked again: "So, what kind of truth can be used to benefit one party?" ”

Mr. Song straightened up the lesson plan and said with a smile: "I have heard that there is a Marquis Xiao in our Tang Dynasty, he once observed that it is not easy for farmers to farm land, so he made waterwheels and plows, and now many places in Yangzhou also use these things, making it more convenient for farmers to cultivate. ”

"Oh? What Mr. said, but that Xiao Shenhou, who has studied battlefield first aid, metallurgy, and Luoyang City, can block Wang Shichong's 100,000 army by himself? ”

Suddenly, when he heard Mr. Song talk about the famous Sanyuan County, Wang Chongan's eyes immediately lit up, and he was a little excited even when he spoke.

Although he is in Yangzhou, because of family reasons, he has always been well-informed, and he is no stranger to things outside, especially for Xiao Han, who enjoys a great name in Chang'an, he has admired him a long time ago, and is determined to be a person like him!

It's normal to say that the little fat man has this kind of thought.

Because a young man who became famous at a young age is definitely better than an old man who boiled until the oil ran out and finally became famous, and he could make the young man feel admiration and admiration!

His eyes gradually became a little blurred, and the little fat man Wang Chongan didn't care whether Mr. Song nodded in confirmation or shook his head in denial.

He still muttered to himself, "I've heard that he's not very old, probably the same as... It's about the same as our court's verdict, right? But look at how powerful people are!

At a young age, he is already famous all over the world, and he has become a marquis! Look at our court judgment again, I don't even have a reputation in Yangzhou City, and I don't see anyone until night, and I don't have a straight line! Hey, it's really the same as my father said, people have to die more than people, and goods have to be thrown away! ”

After saying the latter paragraph, Wang Chongan shook his head in general, and sighed.

However, this is what Xiao Han didn't have the chance to hear, if he did, God knows how he would feel?

Should I rejoice? Or anger, that's a question!

But only one thing is certain! This little fat man will definitely be unlucky, and he will be unlucky!
