Isekai Taneuma

What is Dimension

Guillaume, Scarsaha, and Leonardo spoke out loudly before them.

"Well, Guillaume. You said you could only make 'guns', but why did you come here instead of training there?There must have been a cut. "

He seemed troublesome.

"That's because Waltstein told me that my modern magic (qualia) resembles your fantasy embodiment, Fantastic Vision.When I made a gun, I imagined every part of it in my head and made it feel like I was assembling it.If you say so, I'll definitely think so if you tell me when he looks like you. "

"Hmm, I mean, didn't you ever make parts instead of guns?For example, screws and springs, barrels and barrels, all of these parts together make a gun, but one of those parts is not a gun. "

"... yes, but no, but... is that so?

"By the way, my lord, now that I'm trying to do something new, can I still make my original gun?

"Well, of course... here we go."

Let Guillaume put it into practice.Leonardo looked at it.

"Now, when you created this, how aware were you of the parts compared to the rifles you were about to create?At least when compared to a rifle, it's almost unconscious...?

"That's right...I'm sure it feels completely different... but it's true that they're both trying to do the same thing. "

"Nobody suspects anything.You didn't create a pistol through the same process until now, but it was a familiar pistol that you've been using since you were a kid.You can instantly imagine the parts, the structure, and even if you don't remember each one.So I was able to generate the pistol until the end without hesitation.But the rifle couldn't.By the way, when shooting, do you think about the weight of the bullet, the intensity of gravity, the direction of the wind, and the distance to the target?

"Well, to a certain extent... it's almost sensory.Based on the experience so far, guesswork is stronger than this. "

"The point is, it's the same thing.I will never forget how to swim, walk, or steer a vehicle.Once you learn how to do this, you'll be able to do it wonderfully and unconsciously from the next time.A human being doesn't always have a switch like that in his head.You don't have to build this switch in your head to create a rifle with modern magic (Qualia).... "

"In other words, you can study the structure even more and remember not to be conscious of each part...?

When Guillaume asked, the old man smiled.

"Unfortunately, nothing can be produced by that alone.If you can, it would be strange not to have people with the same abilities as you.Users of modern magic, like you, have been trained to do this task of getting used to it and bringing solid qualities into the brain... or into the high-dimensional ideological world... and then into reality.When it comes to where we borrow the energy to make it happen, it's the fifth particle (Fifth Element) that comes from the high dimension.... "

"High dimension... Fifth element...?

Leonardo nodded with a difficult expression.

"Every time you look at an object, your brain thinks about what it is and searches the ideological world where the brain exists in a high dimension.So when you find the idea of the object of interest and you recognize what it is, it's the first time it's stored as memory in your brain.

However, unlike the perfect ideological world, reality is imperfect, so even the same apple, for example, is actually different one by one, and the same thing does not exist as one.

And yet, the common recognition of "apples" is that a special sense (quality) that connects each apple around the world with the idea of an apple is formed in your brain.

When you make a gun, you don't borrow an incomplete one from this qualia.And when I'm done with it, I'll give back the energy I used and keep it charred.At that time, the energy consumed is the fifth particle, but because it is connected to the high dimension... that is, the ideal world, you can do this kind of trick.The important thing here is that you are accessing high-dimensional beings, albeit unconscious.Perhaps you're not aware of that..... "

"Ah, I've never thought about this at all.I don't know why I was doing that.How did you do that?

"It's possible that you're doing it spontaneously, even unconsciously.Gravity, for example, is one of those things, but it's going to be a lot easier to talk about, so let's put it behind us... Now, all you have to do is recognize that this fifth particle is coming from a high-dimensional direction and working on your brain.Well, that's not difficult..... "

Leonardo said to Scarsaha, not Guillaume, who was twisting his neck with an expression he said he didn't understand, but stretching his spine next to him.

"Scarsaha. How many spatial coordinates are there in this world that we all know?

"There are three. It's called four-dimensional space-time, including time."

"Well, three dimensions just shows how many of these axes there are.In order to show a certain point in the three-dimensional space, we can take three coordinates and plot them on paper, for example, to visually represent them.However, because paper is a two-dimensional plane, it should not be possible to write three coordinate axes there.

There is pure white paper in front of me now.Let's start by drawing a line near the center of the paper, from the left edge to the right edge.

Then we draw the same line vertically, from top to bottom.Then two lines intersect around the center of the paper to make a cross.Mathematicians call the transverse direction of this orthogonal line the X axis and the longitudinal direction the Y axis to represent the plane.

However, their world is usually represented by three coordinate axes.As it is, the plane cannot represent space even if it is represented.So I want to write the third line, but the trouble is that there is no depth on the paper, so the third line orthogonal to the two XY axes and the Z axis cannot be written.

In fact, however, they didn't have much difficulty writing this Z-axis.Mathematicians draw a line diagonally to intersect the XY axis and write "z" to attach to the line.

Needless to say, paper is a two-dimensional plane, so what's written there is just a line of vertical and horizontal licking.However, when they look at it, they recognize it as a coordinate axis with depth, and they can capture the object there in three dimensions... It means that a three-dimensional space has appeared on paper that has only two dimensions.

In other words, for example, this is only a twelve line segment, but it should look like a three-dimensional cube with a vertical and horizontal depth in your eyes.

How can you recognize what is written on two-dimensional paper as a three-dimensional object?As you may already know, it complements your brain so that it looks that way.

To tell the truth, from time to time, they only see the world flat.Their eyes are not looking at the world reflected on a two-dimensional screen called the retina, so the information they get from it is always two-dimensional information.

And yet, they don't realize it because they instantly convert the data of the plane that the brain enters from the retina into three dimensions.The brain is very good at reading three-dimensional spaces.The brain must have evolved that way, because they were tied to a three-dimensional space and were alive.

So, what if they lived in four dimensions?

Perhaps the eyes had evolved to see three-dimensional vision, but the prediction was that the brain should have evolved to capture the four-dimensional space from the two-dimensional information that had been reflected in the retina as before.That said, without even having to complicate the evolution of the body, it is easy to express things in four dimensions.

If we're talking about the coordinate axis earlier, it's possible to plot four-dimensional coordinates in two dimensions by adding a new diagonal line called w in addition to xyz.Similarly, five dimensions and six dimensions can be successively added as many dimensions as are abstract.

However, even if we extend the axis, we do not recognize the four-dimensional space, because we do not understand the view of the four-dimensional space.Therefore, this method is meaningless unless you are a four-dimensional person..... "

"Wait a minute, Leo.I don't know.... "

When Guillaume shows the surrender pose, the old man laughs bitterly.

"The story is too abstract to understand.Well, don't worry, that's not what I said at first.If you keep your mouth shut, even if you don't know it now, it will definitely help you later....

In the first place, do you have a correct understanding of what dimensions are?Dimensions are the number of pieces of information needed to represent them.

Normally, what's called the "O-dimensional space" represents the minimum number of coordinates needed to represent a point in that space.

By the way, this is the minimum number, so maybe there's more to it?For example, two coordinate axes of xy, which are shown vertically and horizontally on a two-dimensional plane, and a z-axis, which is shown diagonally, are created.This z-axis does not represent the depth of space, it is simply a diagonally extending coordinate axis.

The point on this two-dimensional plane can be represented by only two of the x- and y-axes, but you can see that even if there are three coordinate axes of xyz, there is no problem.If there are fewer coordinates, it will be troublesome, but if there is a lot of information, it will not be troublesome.

Now, let's think specifically about what happens when we add information. "

When Leonardo said that, he took out some of the paintings that were covered in the sheets so as not to cover them with dust and began to line them up.

"What we have here is a picture of Tsubaki... as you can see, it's drawn on a plane, and you can feel the spread of three-dimensional space there.If you subdivide this into pieces of cake, it should only contain the "color" painted on the plane, but if you look a little further away, you can feel the wonder and depth.

Why does it look three-dimensional?Needless to say, that's because it's packed with information like that.The human eye is made to be large for nearby ones and small for distant ones.And the place where the light is hitting is bright, and the place where it is not looks dark.

Perspective methods and shadows are expressed in the painting, so the viewer did not create an illusion and remember the three-dimensional feeling.Vertical and horizontal, colour and perspective and shadows... this contains at least five dimensional information.It contains more information than the actual spatial coordinates, but the point is that you can't express reality unless you add that much added value.

On the contrary, I can see the painting from a long time ago because there is not enough information about this perspective and shadow.Because of this, religious paintings before Renaissance almost didn't feel three-dimensional... but instead they contained other information.

Once upon a time, the icons and murals decorated in the church were narrative because they were painted to spread the teachings of the Bible to people who could not read.Probably, there were two or more scenes in one painting, and the two of them had the same person, expressing the switch of time and place.I mean, there was no time line in the picture.

Some attempted to describe the expansion of space by drawing motion itself, not just static scenes.

In the eighteenth-century Turner depicted the locomotive running through the mist with a blurred perspective and extreme perspective, showing something called "speed" that would not have been visible in the original stopping picture.

Monet's "mustache" depicts two pairs of mothers and children walking in a calm and cheerful atmosphere.It is said that these two sets of mothers and children are actually the same person and may represent the flow of time... but more important than that is the subject of the flower.As you can see, the only red dot that seems to be the flower of the hippopotamus is the paint, but you can see that there are flowers in the eyes of the hippopotamus that sway in the breeze, right?

In this way, the painters used various techniques to cut and paint the space.Conversely, some attempted to paint things that were invisible.

Dali depicted Christ being sentenced to death in the higher dimensional space, not in three dimensions.Behind Christ is a cross divided into eight cubes, and his body is enclosed in the cross by the four small cubes in front of him.A picture of the cross is shown on the ground at the foot.

That's how God showed us that the world we live in is a different, high-dimensional existence.

Pablo Picasso then painted a picture of a woman from various angles.This portrait of Drama Mar is an impossible two-dimensional painting, but it feels much more three-dimensional than any other painting.....

https://en.wikipedia.org/wiki/Portrait_of_Dora_Maar

Unfortunately, Tsubaki used to paint only in a realistic way, but in this way, depending on how information is put on and how things are viewed, the three-dimensional space has various faces.Picasso's painting and the painting of the pigeon paint the same space, but the impression is quite different.And Dali tried to draw the space itself in more than four dimensions.

As you can see, surplus dimensions of more than four dimensions should actually be able to "see" depending on how information is captured.Only humans don't know how to do it.Perhaps, if a four-dimensional person saw the cross of Dali, he would feel it in a four-dimensional way, as if he were looking at Icon. "

"... can Leo see it?

"Is it a feeling of seeing or recognizing?And you're supposed to have the same cognitive abilities as him. "

"Me too....?No way, I'm not conscious at all. "

Then the old man shook his head.

"I'm just not conscious, I'm actually watching.Demonstrating quality is synonymous with seeing it.The pistol you are producing is originally known as the Idea Realm, or it exists in a higher order space outside this world.Your brain is pulling it out using the fifth particle energy.You can't do that if you don't see it, right?

I'm not going back there first... but you can generate the love gun you've been using all your life, but you couldn't generate the new rifle.That's because the difference in your perception appeared in the quality generated in high dimensions.The quality of your life's love gun is infinitely close to the idea of a gun, but the quality of your rifle is still incomplete.Therefore, if you want to complete this, you need to have a four-dimensional perspective and generate a quality closer to the idea.

This four-dimensional perspective is equivalent to seeing all of the three-dimensional matter.It's not a big deal to look at parts one by one… it's about looking at the molecules, weights, colors and structures that make them, and your experience of using them all the time.So, if you want to get a new modern magic (qualia), you have to get that "sense of reality" first... "

Well, I see, I have no idea.

Guillaume proclaimed, and Leonardo smiled bitterly.Guillaume's spine was itchy and his body was about to twist, but he twisted his head in an attempt to understand.

"... I don't know what you're talking about, but the point is, you know better about the rifle I'm trying to make?That's what I used to do with sandals.If we keep using this, we'll be able to generate Qualia someday, right?

The old man nodded unexpectedly lightly.

"I bet you can.Since you can already unconsciously see the four dimensional space... if you keep using it, thinking about it, and recognizing it... but when will that happen?

That would be equal to or more than Guillaume's lifetime impression of a love gun.He understands it.

"... I see. It's too late for that."

"I'm sure your lord wants to do it.Then it would be the shortest way to understand the four-dimensional perspective. "

That's why it's not so convenient and easy to roll... Guillaume said with a calm expression, sighing.

"I don't know at all... even if you look at it, you don't actually see it, do you?Think with your head. "

"Dear Left, it's not something you can capture with five senses.But let me just say that this is the first time I've ever been conscious... "

"Now, give me your hand.I'm not as smart as you are.It's more like getting used to it than thinking about it.In the first place, what is that four-dimensional space?Is it really there?

"Yes... that's for sure.There is also a high-order existence.He saw it when he was dying.It's called the Spirit in this world. "

"Hmm...."

Guillaume has incredibly confused eyes.The old man shook his head.

"I don't think you can believe it because you didn't actually see it.So why does it exist? Let's chew it up a little bit and explain. "

"This time, please make it clear to me."

"I can't help it... then I'll tell you a story that will inspire you.This is not an event of our time, but a fairly futuristic one.Therefore, Feng doesn't have to say that he knows normally, and if he does, he will quite understand that you are struggling. "

"What...?

When Feng was named, Guillaume's eyes clearly changed.Originally, the reason why I came here was also because he left me, and I guess I have a strong feeling that I don't want to lose.After confirming it, Leonardo started talking with a faint smile.
