"There is such a country in the world, called the Plane Country. Pen & Fun & Pavilion www.biquge.info here, everything is flat, the land is flat, the mountains and rivers are flat, and even the people are flat.

The poorest and humblest is the isosceles triangle, the noblest is the circle, the most frightening is the straight line, and here is everything you want to know......"

Lin Han quickly wrote the introduction, he is telling the whole story as a flat countryman, and this story will be welcomed by many people!

Perhaps the writing of "Flat Country" is not very moving, but its thinking is definitely the most peculiar, and reading this novel should focus on these places.

"Imagine a huge piece of paper filled with straight lines, triangles, squares, pentagons, hexagons, and all sorts of other figures. These figures do not stay still somewhere, but move freely around, on, or within a plane, but are powerless to jump out of this plane and cannot sink. It's like shadows, those shadows that are real and have bright edges. In this way, you will have a very correct impression of my country and people!"

The first few chapters are about the essence of the flat country, the story of the novel is not strong, the main line is not very clear, it is more like an encyclopedia or a travel introduction, starting from all aspects to introduce the plane country.

First of all, I gave a general introduction to the essence of the flat country, and then I started talking about the climate, and then we came to the situation of the house and the flat country, and even introduced the women in particular, how they identified each other, what was the color bill, the rebellion of Clomatis, etc.!

This is only the first part of the novel, the other part is the introduction of the linear state (one-dimensional) and the space country (three-dimensional), and finally the reasoning of multidimensional space.

This structure had been set up in Lin Han's head, and now all he had to do was to add specific things to this structure, which would be much easier.

"When I was in Space Country, I heard that your sailors had similar experiences when they crossed the sea, looking out at some distant island or coast on the distant horizon.

The distant islands may have many wide bays, headlands and uneven angles.

However, in the distance, you can see nothing but a continuous gray line on the water, unless your sunlight reveals its shadows and shadows through the chiaroscuro.

And that's what we see when a triangular acquaintance or other acquaintance approaches us. Since we don't have the sun here, and we don't have any shadows like that, our vision can't be as helpful as you spacefarers.

When our friend gets closer, we see bigger lines, and if he moves away from us, the lines get smaller. But he still looks like a straight line, whether he's a triangle, a square, a pentagon, a hexagon, a circle, or whatever, he looks like a straight line!"

The other party in the eyes of the residents of the flat country looks like a straight line, which is something that is repeatedly emphasized in the novel.

Lin Han was writing so fast that he didn't even know how he should deal with this novel!

……

In the evening, the first thing Chen Jiaxuan did when she came back from work was to hold the naughty Chai Chai in her arms.

It's a pity that she enjoyed the same treatment as Lin Han, and was disgusted by her own dog!

"Don't look at me, it doesn't usually play with me except when I'm holding food in my hand. Lin Han spread out his hand and made a helpless gesture, whoever let the two of them buy a dog would be irresponsible.

Chen Jiaxuan dragged her high heels aside, she sat on the sofa, looked at the firewood scurrying in the corner, turned her head and said to Lin Han: "You said that you would come back in the afternoon to write a new book, are there any signs?"

Lin Han snapped his fingers, he patted his chest and said, "It's not just the beginning, I even wrote the beginning! Do you want to be the first reader, I guarantee that this novel must be very good." ”

"So what are you waiting for, let me open my eyes. Chen Jiaxuan's tired body immediately regained her energy, she stood up directly from the sofa, and then walked towards the second floor.

Lin Han followed, and he said with a smile: "You will definitely like it, this is the gospel of mathematical scum." ”

Entering the study, Chen Jiaxuan couldn't wait to open Lin Han's computer, she also knew the password very clearly, and when she saw the introduction, the whole person frowned.

"What kind of science fiction is this?"

Although her boyfriend is a master of science fiction, Chen Jiaxuan does not have much interest in science fiction, in her opinion, the genre of science fiction is common in movies, the previous "Immortality" is science fiction has surprised her, and now this novel is also science fiction?

Lin Han pulled a chair over on the side, and he replied: "This should be regarded as an enlightenment book in the multidimensional space, you can definitely understand it, don't be afraid." ”

Chen Jiaxuan's spatial imagination was not good, so she had to sacrifice her life to accompany the gentleman and continue reading.

The part that has been written in "Plane Country" has more than 8,000 words, which is only the beginning of a novel, so Chen Jiaxuan's browsing speed is still relatively fast!

After reading it, she knocked her head seriously and said: "I probably understand the meaning of the flat country, that is, I now use a piece of paper and draw a few figures on the paper, and they are the residents of the flat country." It's still not very intuitive, though. ”

It's not that Lin Han is playing tricks, it's that she has rarely been exposed to this knowledge since high school, so it's more laborious to imagine.

Seeing this, Lin Han took out a one-yuan coin from his trouser pocket, "I'll give you a simpler and more intuitive explanation, this is a one-to-one explanation, and others can't enjoy this treatment." ”

He placed the coin in the middle of his desk, and then said, "Try walking over and looking at it, close to the table, and keep your eyes on the coin." ”

Although Chen Jiaxuan didn't know why, she still did it, bent over and stared!

"What do you see?"

"A coin!"

Lin Han patted her buttocks and said angrily, "What about the shape?"

"A circle, a circle. Can you still see the square?" Chen Jiaxuan straightened his waist, and then grabbed Lin Han's hand just now and hit it twice.

Lin Han walked to the other side of the desk, he squatted down and said, "Now, you learn from me, squat down, slowly lower your gaze, and you will see this coin slowly turning into an oval." Finally, keep your eyes on the same plane as the desktop, and you can take a look at it. ”

Chen Jiaxuan squatted down in the same way as Lin Han, and she was surprised to find that the coin was no longer round or oval, but had become a straight line!

"Now your perspective is the perspective of the flat Chinese people. No matter who else they look at, they are a line. ”

"I see, it's amazing!"
