Reading through the book: The evil first wife of the first assistant family is a miracle doctor

It's very simple. He drew two rows of squares, four on the top and four on the bottom. One blank square and one crossed square, interlaced with each other.

The question raised by Che Chi is to separate and classify different squares with just one cut.

How can it be possible with just one cut?

Some of the people present knew about it, some didn't, and they all gathered around the paper and meditated.

Su Moyang also frowned and thought.

Jiang Yuanluo sighed and shook his head without any thoughts.

"I suspect Che Chi is deliberately making things difficult for us. There is no solution at all. How about we just admit that Dayan can't solve it this time and let them tell us the answer."

"But what if they really have the answer?" someone asked.

"My father asked people to question the reclusive Mr. Su Mi, but even he couldn't figure it out. How could a wise man in Che Chi Xiaoguo come up with such a tricky question?"

Ye Qianqian doesn't know whether to be wise or not. She only knows that many primary school students can solve this problem.

This is not because the ancients were not smart, but because they had never been exposed to a type of knowledge-geometry.

Of course you will never be able to solve geometric problems using inertial thinking, once you change your perspective.

That's really just a matter of scissors!

"Bring the scissors."

Hearing what Ye Qianqian said, Su Moyang's eyes suddenly lit up.

He knew that no one could match Qian Qian's brains.

"Brother and sister, come and try." Jiang Yuanluo moved away.

Ye Qianqian picked up the paper and folded it.

Several people nearby shook their heads and persuaded: "We have tried this folding method, but no one has succeeded."

Ye smiled lightly, showing eight teeth and his voice was clear.

"Then have you asked someone who knows how to cut window grilles to try it?"

Of course, such a serious problem is all involved by a famous wise man from Dayan, a window cutter...

Besides cutting some flowers and pasting them on the window, what other things can be seen?

While everyone was confused, Ye Qianqian had already thought about it, picked up the paper and folded it.

She didn't fold it neatly along the drawn lines, but folded it in half from the middle of the grid, then folded the paper inside out, then folded it into a triangle, and then into a triangle again.

There was no hesitation in scissoring the middle of the triangle.

Isn't this all cut into pieces?

"Open it and have a look?"

Su Moyang and Jiang Yuanluo reached out at the same time and unfolded the folded pieces of paper hesitantly.

One square with a cross, one square with a blank, cross, blank...

Classification of both parties...

"Succeeded?" Jiang Yuanluo's voice was still full of disbelief, and he carefully distinguished it again.

There is really nothing strange about this. Once you change your thinking, you will understand.

Su Moyang completely figured it out.

I guess if you encounter such a problem again, you will know where to start.

Others thought about it and understood, it turned out to be that simple. They had thought too complicated before, which made their minds become a mess of threads that could not be separated.

"No wonder my sister-in-law said she was looking for a window cutter. If she had found her earlier, she would have been solved a long time ago."

At this time, although everyone praised Ye Qianqian for being smart, they didn't think much about it. They just thought that she understood the secret because she knew how to cut window grilles.

This Che Chi man is really cunning. He has troubled Dayan for two years with such a simple question.

Ye Qianqian looked at everyone's expressions and knew what they were thinking.

They still underestimate the enemy.

According to her knowledge of Chinese history, geometric shapes were gradually introduced into China from the Yuan Dynasty, and it was not until the Ming Dynasty that formal geometry was established.

Che Chiren has now discovered geometry, and must have begun to study the wonderful uses of geometry in life. Although it is still in its infancy, it is only the simplest problem, but it is already ahead of Dayan.

Su Moyang shook his head, "Although the question seems to be the simplest, we at Dayan have been unable to figure out the answer for two years. This shows that the question itself is still tricky, and you just can't expect it."

"My husband is smart." Ye Qianqian praised him without hesitation.

"Can the lady explain a few more words to us?" He looked at her with burning eyes.

ha!Trying to trick her knowledge again. Doesn’t she have half of the credit for his career as chief assistant in this life?

Ye Qianqian glanced at him, "This is a very profound knowledge, and this one is just the simplest introduction. I'll give you a slightly more difficult one. Let's see if you can solve it."

Ye Qianqian took another piece of paper, cut a small square in the middle, and took another saucer.

"Now, please pass the saucer through the middle square hole without damaging the paper."

"How is this possible? The hole is so small."

Jiang Yuanluo finished speaking subconsciously, and then touched his nose sheepishly. Since it was made, it must be able to pass through.

Everyone took the paper one after another, made holes according to the instructions, and started studying with the saucers.

They tinkered for a long time, but couldn't find a way to cross.

In the end, Su Moyang and Feng Tao found the right method at the same time, folding the paper on both sides toward the middle to form a larger gap for the saucer to pass through.

The same principle as before, as long as you think of it, it's just a move.

But some people can't get through it because the square holes they cut are too small. Ye Qianqian seems to have drawn them casually, but he calculated them visually.

"Do you know why? Because there are conditions for a round disk to pass through a square hole. The diameter of the circle must be less than twice the side length of the square before it can pass through."

So, it's really a science.

Ye Qianqian didn't solve the first problem just because she knew how to cut window grilles.

In fact, she doesn't know how to cut window grilles either.

"Brother and sister, what kind of field does this belong to, and where can this knowledge be used?" Jiang Yunluo asked shamelessly.

As expected of a man who wants to be an emperor, he does not regard this as a small game, but immediately thinks of its application.

Of course Ye Qianqian is not stingy in giving advice.

"In many aspects, the most common ones are architecture, house design, and construction drawings. This is called geometry. The most commonly used ones are square, rectangle, triangle, parallelogram..."

Ye Qianqian took out the charcoal pen, drew on the paper and talked at the same time, and quickly drew a 3D house drawing.

"Look, if craftsmen could draw such drawings, wouldn't the construction be simpler and problems could be discovered first?"

"Wonderful! Brother and sister! Now I really believe it. You are indeed as Yuan Guang said, you are profound and knowledgeable, and you are a wonderful person in this world!"

Jiang Yuanluo felt as if he had found a treasure, holding the blueprint and praising it.

If houses are built like this in the future, they will not only be beautiful, but also very strong!

Ye Qianqian glared at Su Moyang, "What are you talking about again!"

Su Moyang and Yourong Yan said: "I'm not talking nonsense, that's how you are."

Those who were disdainful of Ye Qianqian just now because of his appearance also changed their minds.

Sure enough, how could Brother Yuanguang's vision be so bad?

Now it seems that his appearance is not bad, his eyes are clear and transparent, black and white, and his voice is pleasant, which makes him feel refreshed!
