I am the cook, but I am Li Er's son-in-law

"Of course it's possible." Yin Xuan nodded.

Although Li Shimin had already guessed this in his heart, when these words came out of Yin Xuan's mouth, he still couldn't help feeling agitated.

Can Sheji also be calculated?

"Please teach me, sir." Li Shimin took a deep breath, stood up and cupped his hands towards Yin Xuan.

Yin Xuan glanced at him: "Isn't the method already laid out there? Knowing all the conditions and collecting the right amount of data, you can draw a reliable conclusion."

Li Shimin was taken aback for a moment.

Yin Xuan knocked on the table: "What do you think is the difficulty of this matter? Is it the result of the final deduction?"

"No."

"It is to obtain conditions and collect data."

After speaking, he paused for a moment, looked at Li Lizhi, and asked, "What data did you collect in your research on fireworks?"

Li Shu snapped her fingers and began to count: "When the gunpowder is fired, the force generated by the expansion of the gas, the work done, the toughness of different materials, and the time it takes to fly to the highest point."

In a series of cases, Li Shu reported a lot of data.

Yin Xuan waved to Li Shimin: "So have you seen it? A mere firework is just a dead thing, and it's already so troublesome."

"Let alone people?"

"And the whole country is made up of different classes, and different classes are made up of different families, and different families are made up of different people."

"Not to mention whether reliable data and behavior conditions of a person can be collected, but even if it is collected, how to collect the entire data?"

Li Shimin sat down and nodded, feeling a little lost in his heart.

It was Yin Xuan who said that he couldn't do it that Li Shimin believed Yin Xuan's words more and more.

"If you can do this, can you really study what will happen in the future?" Li Shimin asked coquettishly, a little unwilling to give up.

Yin Xuan nodded: "Didn't you say it, of course it is possible."

Li Shimin nodded, and poured down all the wine in his hand, not knowing what he was thinking.

After a while, he asked again: "So this is actually your greatest knowledge, shopkeeper?"

Yin Xuan nodded, then shook his head again.

Li Shimin was taken aback, looked at Yin Xuan, a little at a loss, nodded and shook his head, what does this mean?
"My greatest knowledge, in fact, can be summed up in two words." Yin Xuan raised a finger and spit out two words, "Science."

science?

科？
Li Shimin frowned. He had read hundreds of schools of thought, but none of them seemed to be named "Ke". This is an unfamiliar knowledge.

"What is science?" Li Shimin asked for advice with a respectful attitude.

Yin Xuan said softly: "A way to understand the world and rebuild the world's cognition."

Many people have some misunderstandings about science. They think that mobile phones, computers, rockets, and cannons are called science, but they are not. These are called "science and technology", and the focus is on "technology" rather than "science" .

The technology obtained by means of scientific cognition and research.

Science is actually a way of thinking that studies, recognizes, and solves problems, formulates them in detail, and analyzes every aspect of them.

Some people have bad eyes.

On the one hand, it is said that no science was born in this land, but on the other hand, it also praised the two river basins and praised them for having science in ancient times.

In fact, it's just a double standard.

On the one hand, the standards of scientific cognition are imposed on this land, and on the other hand, mathematics and astronomy in the Mesopotamia are held high, saying that they are the germination of science.

What a disgusting face.

In terms of science and technology, science has already taken root in this land, and in terms of scientific thinking, psychology is also the germination of science.

The four words "integration of knowledge and action" are the most important four words in scientific thinking.

To "know" and "do".

If the thinking of "scientific cognition" has not been produced, then naturally there is no science, whether it is this land or the Mesopotamia.

And if this way of thinking is produced, no matter how low the technical ability is, it is still science.

Yin Xuan's explanation made Li Shimin a little puzzled, knowing the world, reconstructing the world's cognition?Isn't that the same thing?
And there is something easy to learn about the world.

The whole world is right in front of your eyes.

Yin Xuan shook his head, didn't explain further, just dropped a sentence lightly: "After this period of time, they have researched cigarettes, bah, fireworks, and I will teach them another fun thing."

"When the time comes, you can come and have a try on the gadgets that are made. It will give you a very different experience."

Li Shimin nodded blankly and agreed.

Li Lizhi and Li Shu raised their heads and looked at Yin Xuan in surprise: "Brother Zhengyang, what's so interesting?"

Yin Xuan smiled slightly: "Go, I will tell you after researching the fireworks."

The two little girls curled their lips, lowered their heads, and looked aggrieved.

Next, Yin Xuan plans to teach the two of them how to refine glass and cement, which is also the easiest achievement of science and technology.

Needless to say, the glass, the wine utensils in my restaurant should be changed, these ceramic wine utensils are becoming less and less suitable for the style of my restaurant.

As for the many uses of cement, although it is said that the Big Wild Goose Pagoda will not collapse for a thousand years, and the brick and wood structure is also very stable, Yin Xuan is more or less uneasy.

Things like multiple cements are also safer.

At least ask for peace of mind.

Li Shimin looked at Yin Xuan, and felt as if a door was slowly opening in front of him, but only a ray of light came out, shining on his face.

Dimly, he could see an extremely beautiful and beautiful girl inside the door, which made his heart itch, but he couldn't push the door open.

If you continue to ask, Yin Xuan just waved his hands, what did you say, you can't understand what you say, why tell you, haven't you already taught your daughter, ask your daughter for advice, and so on.

This made Li Shimin's heart itch even more.

In the afternoon, Li Shimin, who was full of food and drink, took his two daughters back to the palace. It seemed that he planned to ask his daughter what "science" was.

Yin Xuan hummed a ditty, picked up the wooden stick Yin Lulu put in the corner, and felt like he was Mr. Jiang, fishing with a straight hook.

Zhou Bu walked in with a wine gourd in his pocket, "Shopkeeper, our wine has been brewed."

Yin Xuan's eyes lit up and he beckoned him to come in.

Zhou Bu found a wine cup, poured out some wine, and there was a splash, and there was a small half bowl of clear wine, with some fine foam floating on it.

"Shopkeeper, try it!"
