What you have there is a mix of Y and X still. Its not a 4D object just as an image of a "3D object" isnt one untill physical. Unless you are trying for an artists impression but then you could draw it as anything =P

I have always had an easy time understand and seeing both with 'lines' and geometry a 4D shape. What I fail to understand is what relevance can this have in the super powers of reality. Easily enough, what would a 4 dimensional anything look like, if at all possible in a conceivable physical. Does this like the drawn 2nd Dimension have only a place on paper? hahaha.

cassio: Giving people a more intuitive understanding of 4-dimensional geometry gives them an advantage if they start learning either a) relativistic physics, in which you think in terms of spacetime as a united 4d manifold, or b) mathematical analysis. multidimensional models are very important for putting together statistical models. The visual interpretation is not something you'll ever manage to perceive with a real 4d object, but it helps to get your brain thinking in the right mode.
September 4th, 2006

We see three-dimensionally, unless you're blind in one eye. Unless you're talking about what we're perceiving at any given instance, and not what we're constantly perceiving.

any given instant*
September 4th, 2006

Meh, my wording was unclear there. What I meant is... unless you're talking about the image after our brains combine two images from both of our eyes in a given instant into one image. Anyway, not an important part. It just stuck out to me :P.

I still can't see them in my head, but I've always known they were real. But thanks for trying.
September 4th, 2006

"We see three-dimensionally, unless you're blind in one eye" - you don't actually see 3-d with 2 eyes. You see two slightly different 2d images, and your brain extrapolates 3d data from the difference between the two.

Z= .5Y+.5X as a projected 2D image; It's not REALLY that, so your whole subsitution for W is wrong. In that case, W isn't even a new dimension, is just another projected vector.
September 4th, 2006
(1)
"W isn't even a new dimension, is just another projected vector." Yes. Just like Z. NEITHER OF THESE VECTORS CAN POSSIBLY BE SHOWN ORTHOGONALLY ON A 2D SCREEN.

So what happens when you stand in the middle of a railroad track? Is Z the left rail and W the right when you project them onto a screen?

"So what happens when you stand in the middle of a railroad track..." The effect you see when standing in a railroad track doesn't happen at all in "projected" views. It happens only when using proper vanishing-point perspective. This image uses isometric perspective, in which parallel lines remain parallel rather than meeting at a vanishing point.

By changing x into a negetive, you prove nothing!!! The 4D can be experienced as a 3D world with movement or a 4D without. It is considered that there are multiple layers to the fourth, ergo there would be much more and it would be even more confusing.
September 4th, 2006
(0)
yes that is a 4-d object but a 4-d object is 1.impossible to see with the human eye and 2.impossible to entirly represent on a 2d plane so your end result ends up looking like a hexigonial prism

thank f*ck someone explained it at last. I can go all the way up to 5 dimensions on a 2d projection, and it's easy to make a 4 dimensional model as a 3d projection using wires.
September 4th, 2006

so could the lines connecting the two cubes in the hypercube be thought of as representing time, and that the two cubes are the same cube at different points along the timeline of the cube's 3-dimensional universe? because i heard somewhere that time can be thought of as the fourth dimension.

Okay, so mathematically and geometrically it is possible to represent four-dimensional objects. That still doesn't mean they actually exist. Hell, let's go crazy and put two more axes on there, and talk about six-dimensional objects like they actually exist, too. It'll be a good time!

Owly1 wins. 3d means three dimensions, vertical, horizontal, and depth. the 4d object doesn't have any more dimensions than the 3d does, it just has a more complex shape. In essence it's just a really fancy 3d object.
September 4th, 2006
(0)
If that doesn't convince you, try making your 4-d object in a 3-d modeling program. You can do it rather easily. Why is this? because it's really just a 3d object :P

It's difficult to explain 4D, especially in 2D, because it's not something that people are used to seeing, and since people don't think, they can't imagine it. 5'd for effort though.

And I understand what you're saying about a screen only allowing 2-D. However, in our universe at least, there are only 3 dimensions of space. Your argument makes no sense to anyone with a half decent education, and more importantly common sense. I also like how you're so smug in thinking that you're right too. Get a clue.

Oh and the "impossible to represent on a 2D plane" guys are the dumbest. A 4D object is about as representable on a 2d plane as a 3d object. Like it said in the ytmnd (and this is a long known fact) the 3D obects are on a 2D surface.

In our universe, there are three or four dimensions, depending on whether or not you count time as a dimension. This does not prevent us from projecting from four dimensions into two dimensions, just as the fact that Newton was probably wrong about how the universe works doesn't prevent us from talking about and simulating Newtonian physics.
September 4th, 2006

Um guys... "time" itself is not the 4th dimension. Just because it said that in the preview for the Blinx game for Xbox doesn't mean it's true. It's much more complicated. also 5'd

but every point in that shape you made can be expressed as (x, y, z). if you included the negative sides of your axis' you'd see that the w axis was just a rotated version of the z axis you drew. the 4th dimension is time, k?

unaidedcoder, think of the x, y, and z axis' as they would actually appear in a 3d space. also consider the planes that each axis creates. draw any line starting from the origin 90 degrees from z and you'll see that line is already defined with (x,y). and any point in that cube thing can be defined as (x,y,z).

Dude, w is to z as x is to y. That's the point. You are working on the rationalization that you cannot have a natural 4D object. You cannot see a 4D object in the 3D way of thinking you are using, like how yu cannot see a 2D object in 3D properly.
September 4th, 2006
(0)
Fail. Not only are X,Y, and Z incorrectly definited (The way you have it would be like flipping x and y on a 2-d graph) but W is just another aspect of the Z plane. You're not making anything that can't be described by (x,y,z)

Well sarsamis, you are right. To make the 4d object physically real is impossible, as you cannot make another right-angle at the points of the 3d cube. You need to imagine it as a 4d projection onto 3d, much like the 3d projection to 2d done initially for the cube.
September 4th, 2006
(0)
i understand that a 4d object can theorretically exist. it's just that spazdor's explanation of it isn't very good, when a square is projected depth is aded to what was once a 2d object. but when a cube is projected in that same manner then you are just adding onto already defined dimensions.
September 4th, 2006
(0)
the 4th dimenson is usualy considered to be time since after you define a point by its legth from the origin, its height from the origin, and its depth from the origin then duration is seemingly the only thing that can further define that object.

Attension sarsamis: I don't know about you, but *I* am a four dimensional object. There's no theoreticality about me. I existed, I exist, and I'm optimistic that I'll continue to exist.

I downvote this, not because it's wrong (it's the closest we've come on YTMND to being right), but because there is no NEDM.

x,y,and z are all perpendicular to one another and parallel to none. Make your 4th axis do that, and then you're not the real idiot. ;)

Whoa! slow down! My brain needs to callibrate. Okay, I understand now. NEDM is the centre of all 4d objects.

but the z-plane is not diagonal in relation to the x and y planes, it is entirely exclusive...if the x line extends right to left across the computer monitor, and the y axis extends vetically across the monitor, then the z axis is perpendicular to the x-y plane, not diagonal...

NEDM is the 4th dimension. You are dumb! Nah jk the real reason you are dumb is because you have yet to explain that you are speaking about spatial dimensions and technically time is the 4th dimension and the 4th spatial dimension would be the 5th. kthxbaidumbass everyonefails.ytmnd.com

I think it's funny that some ytmnder are saying the fourth dimension is time when you are actually talking about the fourth spacial dimension. Anyway I think if that is what the fourth dimension was that would mean that(In real life, not on paper) it is just a combination of x, y, and z.

now help me with my calculus homework... F of x = x^2 so find the equations of the two lines that are tangent to F(x) that pass through 1,-3 i dunno how to do it :(

Ok, first we take the derivative of F(x), which is F'(x) = 2x. So now, we construct an equation for the slope of the line from a given point on F(x) to the point (1,-3). Since the Y value is F(x), which is x^2, the 'rise' component of that slope is going to be x^2 + 3. The 'run' component is super easy - run is just x - 1. So, the formula G(x) = (x^2 + 3) / (x - 1) gives the slope of a line through that point on the graph, and through (1, -3).

munka: Now equate that function with your derivative, and we find where those tangent points are. F'(x) = G(x), so that means 2x = (x^2 + 3)/(x - 1). Solve for x, and you have your tangent points. Amirite?

Ok, fine. Now explain the 5th Dimension. I know Superman's enemy- Mr Myxzptlk lives there. But why does he look like a human midget with a purple bowler hat, and why does it interface with Earth every 90 days, and why does his saying his name backwards send him back? Explain that to me, smart guy.

I'm guessing that the only way someone on ytmnd was patient enough to explain something as "complicated" as this would be because spazdor was either allowed to fold through a line in the sixth dimension from one point in the fifth dimension to another (from a non lazy ytmnd to this one) point in the fifth dimension, or he folded through a line in the ninth dimension to reach a completely different point in the eighth dimension.

Honestly, not to sound egotistical, but i'm a smart guy, but geometry is not my forté. Good job trying to explain this, but I still don't get geometry.

Lol 4d is impossible. You have height, width, and depth. There is no other direction. What you labled as w is just z going in another direction.
