The artist display that w-axis is in an opposite direction of x-axis, but in fact it is just lays on the x-axis.

Humm, while I like ExTamplier's construction more, solely having a negative x would require a negative y and z, so ultimately it doesn't matter. That said, I think ExT's illustration makes this point far more forcefully.

Its definitely a goof as the one on the bottom is technically better but in reality neither would be accurate representations of the 4th dimension. Since we live observing a 3d world its hard to imagine an extra dimension and show it in a 2d picture.

I like how they showed the dimension collapse. Look up google images of the fourth dimension

Yeah, credibility like not knowing basic mathematics. Probably not just exclusive to a single person either since this must have passed though several inspections in order for it to be animated.

It would be easier to overlook if it wasn't at the start of every episode. Putting that aside, what do you think about representing DW as an outer layer of a sphere created by rotating all 3 axis at the same time? At least with some animation it would look cooler.

Doesn't really bother me since you can't depict another axis on an XYZ graph since it's 3D and you can't add anymore. They had to draw something, so I think it's a forgivable thing.

^ I agree with Jayden, and honestly, it's not like that little blunder is going to make or break the anime.

Also, I don't think "Dimension Negative X" would be a good name lol. It's fine.
People on MAL refuse to actually enjoy watching anime.

put aside W for a moment and think about heat
every position into space(x,y,z) has a certain temperature, now try to imagine if you could see a number for each point into space(x,y,z) saying what temperature is there, call that "t" for temperature, that number is like an extra dimension describing the temperature of any point into space, so if you decide to use that you have a spacial system with (x,y,z,t)
example: (3 meters east, 6 meters north, 2 meters upside, 34° in that place)

dunno if this will help to understand it :u

In reality the space we live in is positive. No negative dimension has been observed.
If you could find a negative dimension and travel to it you could theoretically draw energy from it (- and + equalize to 0 and create energy).
And because in the real world dimensions x, y and z are not really defined, you can not know if the negative dimension is -x, -y or -z. So you name it W.

I think W=(-x,-y,-z)

The "dimensions" aren't defined to be positive euclidian space, either, so this wouldn't explain it either.
Last time I read about it the world was more or less assumed to be an expanding sphere, which would have negative value coordinates.

Because original is a blatant error.
They show crossover of xyz and w, and they show that y and z keep on going. But w is a continuation of x.

Every time I watch that w-axis it seems wrong, but is already difficult to show 3 spatial dimensions on 2D, so I don't blame the studio. They could have made the w dimension as a distortion on the space though, kind like a weight.

had to look that up cause i don't know the tecnical name, but guess the one used in the example is a scalar field
wonder if W is scalar, vectorial, or any other kind, and which kind of energy is that, since it's used for electricy i was thinking it had to be something magnetic
still i think W is a variable of a field of some kind

Math is by far my best subject at school which makes this depiction of a w-axis even more frustrating for me.
As soon as I saw the image of it I literally thought, "What the hell is this!? That isn't a w-axis! All they've done is gone an extending the x-values into the negatives. It should be diagonal off in some direction not that!"
This almost made me want to stop watching this... But I guess you can excuse it. It's hard to come up with a credible forth dimension is it not? Its not like they go into a ton of detail about the dimensions anyway so its not like it REALLY matters.

Still annoys the s*** out of me.

@ExTamplier even if it is just the negative X axis it would still be on all 3 axes. Its Z and and Y coordinates would just be 0 (that is assuming the point where all the lines come out from is 0).
Either way, it would not be a separate dimension.
If z and y are 0 continually, you don't have 3d. you just have a linear line.

The nice thing about Japanese works is that we really can't rule out that there is a purpose to depicting things this way. I am constantly amazed at the rarefied detail Japanese authors possess, so while the graph is most likely a simplistic way to convey a non-essential plot point, I would withhold judgement because there may actually "be" a point to it.

@ExTamplier since you drew just a linear line, its gonna be a linear line no matter how you draw it (the way you drew it, it is also just a linear line). The line itself will not be 3D, but the space containing it is 3D.

If you drew the line to vary non-linearly in the other coordinates (like a curve or spiral or something) then it would be 3D. Still doesnt matter, since it wouldn't be a separate dimension.

And why would we be unable to have a line in 4D(or more dimensions, for that matter)? A line can always be described by 1 variable, so having x, y, z, w coordinates depending on that would make as much sense as x, y, z.
The main difference is that you know what 3D looks like and can illustrate it.
(And also, you can't draw 3D, it's still 2D as long as it's drawn, that it looks like it could be 3D doesn't mean it is).

the only real(!) way to "draw" 4-dimensional systems is to give each point extra information

for example





P_max_abs (0,2, 5, R10) R10=100°C



edit: the system only works as 4D if the Z-coordinate isn't related to the temperature. this one is better

Actually, I am not sure what you are trying to say with this?
I think you can draw 3D. For example, since we live in a 4D world, even if we draw on a piece of paper like a line with paint, the painted line will have length, width and also thickness. This is 3 dimensions.

Basically, a line, no matter what space it is imbedded into, is always a 1 dimensional object so you can always map it into R^1(for example by taking its length).

As for drawing 3D, of course the paint/ink etc will always have a thickness, but you can't actually see it and thus we can look at it as 2D.
