Carefree Prince In Tang Dynasty

Xiao Runniang opened the locked door of the study and obediently invited the two masters in. Li Xin couldn't help touching her head when he passed her. This little girl has been in the palace without knowing it for more than a year. She is cute and well-behaved. She is also good at doing things. She is a good boy.

Chen Xinheng stepped into the study, only to see a bookshelf with a few scattered books on it. He turned his head to look at Li Datong: "Your ‘study’ is a bit of a misnomer. Just these few books, just cram it under the bed, why not set up a study alone."

Li Xin rolled his eyes and said out of anger: "I want you to take care of it."

Really, I want to ask others for advice, and I have to ridicule other people's study first. It's really... the brain circuit is very strange.

Chen Xinheng laughed, walked forward to the bookshelf, took down a book casually, on the cover of the book was written "Elementary School Mathematics I". As he opened it, he asked: "The so-called mathematics is mathematics, right?"

Li Xin was noncommittal, saying: "Almost. But the scope of mathematics is broader than that of arithmetic."

indeed. These years, mathematics is still at the level of solving various application problems and equations, but the concepts of mathematics are actually more extensive. Even the subjects of topology and logic that may not be classified as mathematics in the eyes of ordinary people are actually mathematics. Branch. Therefore, mathematics is undoubtedly more ambitious than arithmetic.

Chen Xinheng is a very smart person. And as a Confucian rebel, he has always been interested in many disciplines that orthodox Confucianism despise. Mathematical learning is one of them. In fact, Chen Youlan's arithmetic skills were taught when he was a child.

However, Rao thinks he is good at mathematics. Facing Li Xin's so-called "Elementary School Mathematics I", he couldn't help feeling a little powerless. The part of the introduction to the symbols just made him feel a little dizzy. Fortunately, the latter part is fairly simple. He still can barely apply these new symbols that he has just learned, and feels a little bit about the convenience of this symbol system.

In fact, Li Xin had already come up with the big eclipse text. At least in the yamen of the Ministry of Households, the use of Da Shi writing is already a default rule, and abacus has already been put into use in large numbers. However, Chen Xinheng is far away from the court after all, and he doesn't know much about these things, or even knows nothing.

"This is the textbook I prepared for seven or eight-year-old children. Why do you look so hard at it?" Of course, Li Xin couldn't help laughing at Chen Xinheng when he seized the opportunity.

Chen Xinheng glanced at Li Xin, put it back on the bookshelf, and said: "Just look at it." He was afraid that if he looked at it more, he couldn't bear to ask Li Xin for some questions. He always felt a little weak. Up the momentum.

Li Xin walked to his desk and said, "Don't you want to watch advanced applications? Come here."

Chen Xinheng walked over according to the words.

Li Xin took out a piece of paper and spread it on the table, took out a charcoal pencil in his hand, and began to sketch on the paper. Chen Xinheng watched quietly. In a short while, a seemingly complicated device appeared on the paper.

Li Xin squeezed the charcoal pencil and made a few gestures on the paper, imagining in his mind how the water would push the machine. He once saw a picture of this "water drain" installation in the Song Dynasty in a book, but he couldn't remember the details clearly. Fortunately, he is an engineering student himself, so the calculation is not difficult.

"This is?" Chen Xinheng asked suspiciously.

"A blowing device." Li channeled. After speaking, he briefly explained the working principle of this device, from the water inlet, to the water outlet, and then to how the water flow pushes the fan blades, and how the air flow is guided into the blast furnace.

Chen Xinheng listened with gusto, and finally asked, "So what is this device used for?"

"A device used to make iron. You may not know that during the process of making iron, the air flow is closely related to the quality of iron making." Li Xinshun briefly explained the difference between pig iron, wrought iron and steel. .

Chen Xinheng touched his chin and slowly said, "You mean that with this thing, we can produce more iron, and maybe even stronger steel?"

"It's not possible, it's definitely possible. It's just the sooner or later time." Li channeled.

As long as you try a few more times, you can definitely find a way to make steel.

Chen Xinheng smiled bitterly: "This thing is related to the large and small stones falling at the same time?" From this picture, he can't see the slightest shadow of the large and small balls.

Li Xin froze for a moment, then smiled and nodded: "Of course. But it also contains some other content. It is a collection of many content. After all, it is an advanced application." The water flow pushes the fan blades and pistons under the action of gravity. Such a device involves many principles under the classical mechanics system.

"Is this what you mean to'remove the world'?" Chen Xinheng asked with a thoughtful expression, and then his eyes burst into dazzling brilliance.

That's right, that's right. This thing called science is the way outside of Confucianism that he has been looking for!

Li Xin really has this way!
