Chapter 596

The crows made the crowd laugh.

Alice said, "madam, do you already know what the fourth dimension is? Can we really see it?"

"If it's really what I think, then each of us can see it."

"What do you think?"

"In a dream."

"In the dream?" Alice wondered. "What do you think in the dream? We can't control our dreams."

"We can't, but they can," Mrs. Larry said, pointing to Aoki, situ, dewar and suhuilan. "The fourth dimension is not time, nor is it a gravitational surface, but - spirit!"

Aoki's heart was shocked. He suddenly felt that the spiritual force field on the island became dignified, and the three suns in the sky seemed to be twisted.

Alice still didn't understand, "but isn't the dream a chaotic world composed of our memories? It's still three-dimensional! Where does the four-dimensional come from?"

Mrs. Larry smiled: "You can't control dreams. Of course, you don't know the wonderful use of spiritual power. Ludwig and I have studied the subject of independence of spiritual consciousness. Ludwig's research was once very in-depth. Unfortunately, I don't have the talent in this aspect, so I don't know how to control dreams to develop four-dimensional space. Moreover, I'm not a physicist, so I still invite professional people to come back and forth in this aspect The answer is better. "

She said and looked at situ.

Situ said, "we can really regard dreams as four-dimensional space - dreams are supported by spiritual forces, and the material constituting them is human memory. We can also understand them as the projection of the real world on the spirit, that is, the fourth dimension.

The world we live in is three-dimensional. The projection of three-dimensional in two-dimensional will become two-dimensional, and the projection of three-dimensional in four-dimensional will become four-dimensional. However, just like the projection of two-dimensional in three-dimensional, it is just a distorted virtual shadow, which can not change its own dimensional attribute, and the projection of three-dimensional in four-dimensional is also a virtual shadow. In addition, our human brain can only perceive three-dimensional things, so dreams It looks three-dimensional, and because it is a virtual shadow, it is not only distorted, but also chaotic and changeable.

According to Madam, if these words are the projection of three-dimensional words left by four-dimensional life on the two-dimensional plane, and their fourth dimension is exactly the same as the dimension supported by our spirit in the dream, as long as these words are put into the dream and returned into three-dimensional words with spirit, consciousness can perceive the meaning they express. "

Alice said, "but how to restore it? Our brain can't perceive four-dimensional things. Even if you can control dreams, isn't it still a three-dimensional world in the brain's cognition?"

Situ smiled and said, "we don't need to see what the four dimensions are like. As Madam said, the information coding method of civilized language is one dimension lower than the space where civilization itself is located. These words were originally three-dimensional, and we just need to restore them to three-dimensional. Isn't it what our brain is good at replacing two-dimensional things into three-dimensional?"

"The brain is still good at this?" said Alice, puzzled.

"Yes, do you think that what our eyes see is essentially two-dimensional?"

"No, it's three-dimensional!"

The crow suddenly interrupted, "quack, stupid woman, have you ever played Super Mario?"

Alice replied, "you're stupid! Stupid bird!" but curiosity overcame her competitive heart. "Of course I've played Mario. What's the matter?"

The crow said, "Mario is a two-dimensional creature. There's no objection to this, stupid woman?"

Alice said, "no objection, you stupid bird, please don't call me a stupid woman!"

The crow croaked and nodded, "OK, OK, stupid woman! Now imagine a computer in front of you. Mario just stepped on a turtle and there is a green... Mailbox in front of you? Oh, that's the mailbox. At least you see the mailbox, right? But from Mario's perspective, what does he see?... quack, it's a line. Mario can't see the shape of the whole mailbox, There is a line standing in front of him, isn't it, stupid woman? "

Influenced by the crow, Alice seemed to really see the familiar game picture. She nodded unconsciously.

The crow continued, "two-dimensional creatures can only see one dimension, and one-dimensional creatures can only see zero dimension, so Mario sees lines and greedy snakes see points. Humans are three-dimensional creatures. Similarly, people can only see two-dimensional world. You think what you see is three-dimensional. That's what your brain makes up. Stupid woman, do you understand?"

"Ah, it seems to be true! What the eyes see is the projection of objects on the retina, which is flat, just like a mirror. Our brain restores it into three dimensions through the analysis of the spectrum."

Alice suddenly realized that she completely forgot that the crow was still calling her a stupid woman. "What a creature sees is always one-dimensional lower than his space, which is completely consistent with the theory that the information coding method of the language spoken by his wife is one dimension lower than the civilization itself!"

Mrs. Larry said to Aoki, "what a clever bird!"

The crow stood on the top of the green wood, raised his head and croaked a few times.

Alice said, "but since our brain can automatically restore two-dimensional to three-dimensional, why go to a dream?"

"Because we don't know which direction it is projected into two dimensions."

Situ explained, "the human brain can't intuitively perceive and understand the four dimensions, so we can't see its projection direction. Accordingly, it's difficult to grasp the extension direction of the dimension when it is restored.

There are two directions to expand one dimension into two dimensions in three-dimensional space; similarly, there are two directions to expand two dimensions into three dimensions in four-dimensional space. In view of the uncertainty of these text projection planes, it may be projected on any face, and each face has two reduction directions. If the three-dimensional space is regarded as a cube, it has six faces, and each face has two reduction directions A face and the fourth dimension can form a new cube. With its own and its mirror projection, there may be eight three-dimensional spaces and twenty-four planes. The projection direction of three-dimensional text can be any plane. We need to judge its direction, just like the plane drawing of an object. You need to know whether it is a top view, a bottom view or a side view, and then Can be restored to a three-dimensional shape. In four-dimensional space, it is obviously much more difficult. "

"It's too complicated!" Alice sighed.

Situ said, "it's not complicated. As long as the direction is correct, it's just to spend more mental energy to try."

Aoki said, "then try."

He always felt that the meaning of those words was bouncing in his mind, just as an engineer saw an incomplete drawing without any labels. Now they have collected three copies of this drawing, and they have also found a way to restore it. With the joint efforts of him, situ, dewar and Su Huilan, and the scepter in their hand, the spiritual strength must be enough.

Among the people present, only Alice and Mrs. Larry are not awakeners, but Mrs. Larry is a linguistic authority. It is obvious that they will take her with them to interpret the text. Alice knew they were about to start, and said quickly:

"Hey, hey, can you bring me into your dream and open my eyes!"
