Chapter 236 Boiling water and throwing stones!Huo Guang started preparations for running a school

In Chang'an City, here is Le Restaurant.

A few days after the house went on sale, Huo Guang decided to close the restaurant for a few days for rectification.

Said it was closed for rectification.

Actually.

It is because there are too many people in Chang'an City these days, and the tavern is not easy to operate.

Just taking advantage of these two days, he was going to compile a book on science and technology to teach those children.

But the problem is.

Those children from poor families don't even know a few words, so how can they learn science and engineering?
Isn't this playing the piano to the cow!

Huo Guang took this into consideration.

and so.

What he wants to do is not to pass on the knowledge of science and technology rigidly, but to enlighten these children in science and technology.

What is the best thing about enlightenment?
Of course it's a picture?

Huo Guang still remembers that when he was a child in his previous life, he didn't know a few words, but he was very happy to read those comic books.

Words are never the first choice for human enlightenment.

Pictures are!

After confirming that the pictures are the main content and the text is the supplement.

So what should you draw first?

Without the slightest hesitation, Huo Guang drew a picture of boiling water.Because the Han Dynasty did not have the so-called cooking pots in later generations at this time.

and so.

Huo Guang boiled water for painting, and the picture he used was in the shape of a tripod.

Second painting.

What he painted was the design of the steamed ball designed by Hero, an engineer from Alexandria abroad in the first century.

just now.

The era in which Huo Guang lived was the period of Emperor Wu of the Han Dynasty, that is, 115 BC.

The appearance of the steam ball was 100 years later.

But this does not affect Huo Guang directly using Hiro's steam ball to enlighten these children.The steam ball is the prototype of the steam engine that led the wave of the industrial revolution.

The third painting is not a simple painting.

It's a blueprint.

He combined something like a spinning ball on the wheels of a carriage.The rotation of the steam spinning ball drives the rotation of the wheels of the wagon, and the rotation of the wheels of the wagon makes the wagon move forward.

Will this work?
Do not!
This doesn't work out.

The first purpose of Huo Guang's paintings is to enlighten these children in science and engineering knowledge.

Let them know that the steam generated by boiling water can be used in this way.

As for why Huo Guang's first picture was boiling water?
Very simple!
Because boiling water is really the existence that accompanies human civilization to this day.All human technology is inseparable from the link of boiling water.

If one day, human beings can completely get rid of the link of boiling water.

That can only show that there are two situations in human beings.

One is that human beings are extinct.

The other is that human science and technology has been improved across stages, which can directly convert energy into the way humans need, skipping the link of boiling water.

The first three paintings, after finishing.

The fourth picture that Huo Guang wants to draw is the prototype of the steam engine.

A heat engine that uses steam to expand in the cylinder to push the piston to reciprocate to do work!
Even if this Huo Guang can't make it real, can't he still draw it?
You can draw it, but are you worried that you won’t be able to do it in the future?
rest assured!

With the hands-on ability of the craftsmen, as long as they are willing to study hard, it is guaranteed that such things can be made in a few years.

perhaps!

At that time, Huo Guang was no longer alive.

But what he left to the big man was the seeds of hope!
After the prototype of the steam engine was drawn, Huo Guang unconsciously began to draw pictures of the steam engine's functions, one by one.

For example, use the concept map for the engine on the carriage, for example, change the piston driving principle of the steam engine to the piston principle of internal combustion of oil.

even.

There are also pictures of various aircraft, submarines, etc. behind.

Although these things allowed the Han Dynasty to develop for another 400 years, it may not be possible to get them out.

But Huo Guang just wanted to point them in the right direction, and that was enough.

At this point in the painting, the direction of the steam engine is over.

Behind.

Huo Guang elaborated on the more difficult electricity, the basics of chemistry, and even wrote down the periodic table of elements.

Anyway!

He used the knowledge he had learned before to paint as much as possible in a picture mode that people in the Han Dynasty could understand.

to this end.

In half a month, Huo Guang actually consumed nearly a thousand sheets of paper.

When he came out of this restaurant.

Already unkempt.

After tidying up the paintings, I went back to Huo Mansion to wash up and take a rest.

after that.

He recruited blacksmith Ouyang Zhi and carpenter Li Hong.

Except for these two people.

He also specially took Dong Xun over from the racecourse. He couldn't let Dong Xun stay in a place like the racecourse all the time, could he?
of course.

All of Huo Guang's actions are purposeful.

He is not a love brain, he will go crazy when he sees a beautiful woman.

Dong Xun had studied and read with Dong Zhongshu before.Huo Guang called her here, not only to improve her life, but also to let her help him compile books.

Book paper is something that Huo Guang only made a few years ago.

So there is no such thing as printing.

Huo Guang can do printing if he wants to, but he doesn't want to do it right now.Why?Because books and paper have not yet become popular in the whole country, isn't it a problem in the mind to engage in woodblock printing and movable type printing?

perhaps.

After that, he completely took power.

It's not too late for him to get these again.

Besides.

Huo Guang also planned to ask Dong Xun to teach the children of those poor people how to read. Dong Xun didn't have much knowledge, but his literacy was still enough.

Like those rural primary schools in his previous life, the teachers there were all farmers, and some were even vendors selling popsicles on the street.

But these people, as long as they can read, can be teachers.

but.

At that time, it was [-] years ago, and Huo Guang didn't know about it in the future.

now.

Huo Guang gathered Dong Xun, blacksmith Ouyang Zhi, and carpenter Li Hong together, and showed them the design drawings.

Dong Xun didn't quite understand this.

But carpenter Li Hong and blacksmith Ouyang Zhi's eyes lit up when they saw these blueprints.

The so-called experts watch the doorway, and laymen watch the excitement.

Li Hong and Ouyang Zhi didn't know what the designs on these blueprints were for, but from those sophisticated designs, they could feel that this kind of thing was definitely not simple.

"Bo Luhou, you asked us to come to make these things? But how should we do it?" Li Hong asked while holding the blueprint.

Huo Guang smiled lightly, and said, "Li Hong, don't worry, most of these are the jobs of blacksmiths."

"You are here to help Ouyang Zhi."

"After all, you are a master in carpentry and can provide a lot of help to the blacksmith."

Li Hong was not very happy after saying that these were the jobs of blacksmiths.

But then he praised him as a master, this guy, Li Hong couldn't be happier.

He immediately said that he could help with all his money.

But Ouyang Zhi looked at the blueprint, couldn't help frowning, and said, "What are these, have you never seen them before? Huo Yilang, ah no, Bo Luhou, what is this for?"

Huo Guang smiled lightly and said, "Why not, this is to lead the progress of human civilization!"

"Civilization? Culture!" Li Hong questioned.

In this regard.

Huo Guang shook his head lightly, and said, "It's civilization. The "Book of Changes" says, 'Seeing the dragon in the field, the world is civilized'. This civilization refers to the improvement of people's livelihood, as opposed to barbarism!"

"Ahem." Li Hong coughed twice to hide his embarrassment.

Huo Guang didn't care about these, and continued: "The civilization that this Marquis wants to lead can be summed up in six words."

"Boil water and throw stones!"

The words fall.

Huo Guang suddenly turned to Dong Xun, and said to her: "Dong Xun, you can write down what I said."

"Oh!"

Dong Xun nodded obediently, and then began to record what Huo Guang said.

Boiling water, simply put, is energy work.

What about throwing stones?
It is to give power to objects.

Archery, catapults, and thunder cannons can all be said to be throwing stones.

Even the rockets that will fly into space in the future.

Comparing human civilization to boiling water and throwing stones is actually a meme on the Internet.

is it right?
That must be wrong.

But it makes sense, and the metaphor is very vivid.

What Huo Guang mainly does is to enlighten the children of common people's families about science, such as physics and chemistry.

The success of enlightenment is not important.

But the spark that enlightenment ignites is very important.

This is very important, just like our ancestors used tools for the first time.

aside.

Ouyang Zhi, who looked like a big man, couldn't understand Huo Guang's words, so he said directly: "What about boiling water and throwing stones, you teach those children this?"

"Then I will too!"

"What is there to teach children about this thing?"

Huo Guang glanced at Ouyang Zhi, and said angrily, "What I'm talking about is a metaphor, and it's not just a simple matter of boiling water."

"Take your blacksmithing as an example. After you light the stove, what are you going to do next?"

Ouyang Zhi said directly: "Forge iron, quench it, and make the required tools according to the requirements."

Speaking of blacksmithing, Ouyang Zhi has something to say.

After all, it is something he is good at.

Huo Guang stretched out his hand to interrupt, and said: "Stop, stop, who told you to say this, let me ask you, didn't you say that there is something good to teach you about boiling water?"

"Then let me ask you, what happens after the water boils?"

"What are you going to do?"

Ouyang Zhi shook his head directly.

Here.

Li Hong said, "Drink, make some tea."

Seeing Li Hong making trouble, Huo Guang immediately glared at him and said, "Don't make trouble."

Li Hong could only scratch his head in embarrassment.

At this time, Huo Guang picked up a painting he had made earlier, which was the one with the spinning ball designed by Hero.

At this moment.

Huo Guang said to Ouyang Zhi: "Blacksmith Ouyang, I want you to make this kind of thing now. It is hollow in the middle, and it can be filled with water and burned underneath."

"The water is boiled and can pass through the pipe, and the hot air enters the upper sphere."

"Believe it or not, this sphere will spin itself without wind?"

Ouyang Zhi immediately shook his head and said, "I don't believe it, can it turn without wind? Oh, I've been blacksmithing for so many years, and I've never seen such a miraculous thing."

Huo Guang smiled, then looked at Li Hong, and said, "What about you, don't you believe it?"

"Do not believe!"

Li Mu shook his head.

Huo Guang immediately looked at Dong Xun, and before he could speak, Dong Xun said, "Huo Guang, I believe you."

When Dong Xun said to trust him, he didn't mean to believe what he said, but to trust what he said.

Huo Guang knew the reason.

So he nodded, smiled slightly, and said, "Practice is the only criterion for testing the truth. Come on, Li Hong, Ouyang Zhi? Let's make this steam ball next, and you'll know if you try it!"

Li Hong's carpenter's shop belongs to Huo Guang.

Ouyang Zhi's blacksmith shop was also built by Huo Guang.

Huo Guang spoke.

Of course they both wanted to listen.

then.

The rudimentary form of the steam engine, the steam ball, was made after days and nights of processing.

Because this kind of thing is not as precise as the barrel, complex issues such as bombing have to be considered.

So the production process is not difficult.

Just beat the iron block into an iron sheet, and then build it according to Huo Guang's design.

Square is square, and tube is tube.

The slightly more difficult one may be the sphere of the steam ball!
but.

Things that the West can produce 100 years later, although the Han Dynasty is 100 years earlier than him at this time, its original industrial level is countless years ahead of the countries in the Western world.

You know gears, right?

There are bronze gears in the tomb of Emperor Ba in Han Dynasty.

The steam ball is a very simple device, and it was produced quickly with the cooperation of two craftsmen.

Later!

Huo Guang began to show them his magical side.

He first added water to the iron box, then sealed it, and asked someone to bring a pile of firewood and put it under the iron box to burn.

soon.

The water in the iron box boiled, the steam entered the sphere from the pipe, and was ejected from the special opening on the sphere, and steam began to emerge.

Wait until a certain moment.

When a large amount of steam came out, the steam ball started to rotate by itself.

This miraculous scene stunned everyone present.

Especially the blacksmith and the carpenter, who made the spinning ball according to the graphics designed by Huo Guang, but they still didn't understand why the spinning wheel rotated by itself?
"Hey, this is the initial application of boiling water. Ouyang Zhi, didn't you say a few days ago that you can also boil water? Then, do you also know how to use it?" Huo Guang asked with a smile.

Ouyang Zhi scratched his head, looked at the spinning steam ball, he shook his head in embarrassment, and then asked: "Then what is the use of this kind of thing when it spins?"

"It's useless!" Huo Guang spread his hands.

The steam ball is indeed the prototype of the steam engine.

But the problem is.

Saying it is useless is really useless!
Hearing this, Ouyang Zhi immediately said: "Then we have worked so hard to make this thing for the past few days, what is it for?"

Huo Guang replied directly: "Let the students see it!"

"Student?" Several people present looked at Huo Guang at the same time, as if they didn't quite understand what the student meant.

Huo Guang said: "Ah, didn't the Marquis tell you?"

"I built a place outside the city for the children of the common people to learn, but I don't plan to teach them the four books, five classics and six arts."

"I'm going to teach them the principles of 'boiling water' and 'throwing stones'."

"Oh, yes, Dong Xun."

"In the future, you will teach these children how to read and correct the test papers."

Because a few days ago, Huo Guang had already greeted her to teach the children how to read.

and so.

Dong Xun was not surprised by this.

just.

What does it mean to correct the test paper?
Dong Xun didn't understand, so he was surprised immediately, and said, "Huh? Huo Guang, what are you correcting?"

Huo Guang waved his hand and said, "Examination papers, that is, at the end of each month, I will give questions to those children, and then I will give you the answers, and you can mark the answers."

"All correct ones will be given excellent grades, and their monthly household allowance will be exempted; those who pass the test will be awarded good grades, and their household's household allowance will not be exempted."

"As for the failed ones?"

"Just let him go home, what should he do!"
