It's just that Chongzhen still has a doubt, not to vomit and be unhappy.

"Youming, if you want to increase this electricity by a hundred times, how many potatoes do you have to use?" Chongzhen asked with a serious face.

Potatoes are the life-saving food of the Ming Dynasty, related to the safety of the people of the Ming Dynasty is a strategic resource, if the potatoes are used to generate electricity, it is bound to make more people have no food to eat.

But if this electricity is used for war, it is really an artifact given by God, but it is not possible to have both fish and bear's paws, which makes Uncle Chongzhen feel very uncomfortable.

"Hahaha! The Emperor always cares about the suffering of all the people, which is really the blessing of my Ming Dynasty. Liu Hong was gradually amused by the serious Uncle Chongzhen.

Chongzhen actually wanted to use countless potatoes to increase it, and it is no wonder that electricity is really unheard of for these ancients, and they have the right to say that this electricity can only be generated from potatoes.

"Everything is reasonable, the reason for transformation, the chemicals in the potatoes can be converted into electricity, the wind in the mountains can also be used, the water in the river can also be transformed, as long as all the disciples are united and work hard to tackle the tough problems, the sun above our heads can also be converted into electricity!"

Liu Hong gradually talked and laughed, and his face was surprisingly confident.

"And when will it be developed?" Chongzhen asked another question that he was very concerned about.

yes, when will that happen?

If you want to increase the power increase, it is not just talking, which involves too many technical problems and safety issues, and there is no generator at this time, not even rubber, it is very difficult!

"It won't be long, Emperor Taishang, as long as the imperial court is willing to vigorously support engineering, within a few years, electricity will definitely be available for the Ming Dynasty." Liu Hong gradually took a deep breath and said in a deep voice.

Among the various power generation methods such as wind power, thermal power generation, solar power generation, and hydroelectric power generation, hydropower generation is the easiest and most cost-effective power generation.

But that was in the future, and the siting requirements for hydropower are high, and the construction of super dams requires more manpower, material resources and risks without machinery.

But it doesn't matter, he believes in the wisdom of the Chinese people, as long as he points out this road, thousands of engineering heirs can always get everything done.

Besides, he still has the manual in his hand.

"Alas, it seems that I will not be able to see each other in this life, what a pity!" Chongzhen sighed and said.

"People are inherently dead, or heavier than Mount Tai, or lighter than a feather, the Emperor, your kindness and diligence will be praised by future generations, and now you should live more easily, no one knows what will happen tomorrow, right?"

Liu Hongjian did not immediately say nonsense like other courtiers that the Son of Heaven must be favored by God, live a long life, and live with Tianqi, but expressed his views on his superficial understanding of life and death.

Sometimes he wondered what he would do if he had only one day left to live.

Find a place to lament the injustice of fate? Go crying and begging for mercy?

No, no, no, he wants to hug the three cuties in the family, eat the last meal, enjoy the last new moon, and do what he wanted to do before but didn't have the opportunity or guts to do, ......

In short, there will be no self-appreciation, relatives and Aiai.

"Hehe, you will comfort people, but I am not as cowardly as you think, I have long looked down on life and death, and now I am happy, if I have regrets, I only sigh why the ancestors didn't lower you earlier." Chongzhen smiled slightly.

If it had been earlier, perhaps the people of the north would not have suffered so much slaughter!

Hundreds of people, including the oracles, were dumbfounded, and most of the oracles stared at the half-pulled potatoes, two ordinary wires, and dead ants in the tray that Liu Hongji had eaten.

For those of them who have been immersed in Confucianism for most of their lives, perhaps new things are even more difficult for them to accept.

But the young disciples are different, they don't know much about Confucianism, and even many of them can't read and write when they come to the engineering college.

They have a blank slate for natural sciences, physics, biology, chemistry, etc., depending on what the engineering school can teach them.

The reason why Liu Hongjian came to give this class to the disciples of the School of Engineering was to break their blind worship of Cheng Zhu Lixue, and to broaden the horizons of these young disciples and let them know that only science can explain everything in the world is the second.

"Inside this other tray are two iron balls, but the chief of this mountain is no longer in the mood to demonstrate the experiment to you." Liu Hong gradually lifted the red sermon on another tray on the table.

"Interested students can take these two iron balls, one large and one small, go up to the top of this building, and throw the two iron balls at the same time, and you will find that the two iron balls of different weights will hit the ground at the same time.

As for why, the chief of this mountain will not give it to all of you, and it is all up to you to think about it.

If someone can understand it with the science of physics, this mountain chief guarantees that you will go down in history. Liu Hong gradually picked up the two iron balls and let the disciples behind them take a look, and said provocatively.

Liu Hong gradually said that the teachings in the front row suddenly couldn't sit still, isn't this a misguided child?

Two objects, one light and one heavy, fall at the same time, naturally the heavy one falls first, and you can tell you the answer if you go to the street and pull an illiterate old man.

An edict on the side wanted to stand up and refute, but was held down by a colleague next to him.

Li Cunhou's deflated eyes are all in his eyes, and now the Emperor Taishang is here, refuting the mountain chief in public is not a subordinate in the first place, if the Emperor Taishang is displeased again, isn't it that he can't get along with himself?

There is no evidence, so let's wait for the class to find a few colleagues to experiment, so that the mountain master can restrain the behavior of misleading people's children.

It's just that the young disciples in the back don't think so, and now they are almost worshipping Liu Hong, giving them food and clothing, giving them reading and literacy, and letting them appreciate the mystery of all things.

Leave a name in history!

In this life, if you can still be famous in history without relying on the imperial examination, what regrets in this life?

"Now the chief of Benshan announces that from today onwards, at the end of every fifteenth and month, all science teachers will take undergraduate students out to teach!

The Civil Engineering Department went to study pavilions, the Water Conservancy Department went to inspect rivers, bridges and dams, the Mining Department went to explore minerals in the mountains, and the Smelting Department went to the workshops to observe the ......"

Liu Hong gradually calmly and undoubtedly announced the new rules of the School of Engineering to the teachings present, and the study of science and engineering should not only stay in textbooks, nor should it be left to the words of teaching.

In the face of science, we must dare to question the so-called authority.

The College of Engineering should not be an ivory tower, there is Wang Shouren Gewu Zhizhi, and now there are disciples of the Engineering College Gewu Zhizhi, the principle of physics, and the reason of all things.

Let's get out there!

To observe the world, to appreciate the mountains and rivers!

To study the wonder of all things, the smallest of things!

To experience, to try......
