Demensions are facinating the higher they go.

1D- a straight line like this ----
2D- lines connecting to make a shape.
3D- Shapes connecting in many ways to create an object (Humans are 3D, Lamps are too, etc)
4D- This is where it gets interesting. I was discussing with Xard about 4D- and it is very complicated, yet fascinating. Care to try to explain what it is and then 5D and so on?

Well, technically the fourth dimension is time, but I don't know how you'd explain that.

Xard says its Space and Time. He showed me a picture of a 4th Demensional cube. I forgot what its called. He also said it changes the way it looks every time you look at it from a diferent direction.

I suggest using Wikipedia... ;)

4th dimension is one way to measure physical change. It is perceived differently from the three spatial dimensions in that there is only one of it, and that we cannot move freely in time but subjectively move in one direction.

I couldn't really find anything about 5th dimension. So what my thoughts are of 5D - senses. Actually makes you feel like your there.

P.S. there is also 0D - a simple dot.

you were talking to me about it as well.
look at this....

Imagine a 1d person living in a 1d house that is house is just a line,then a 2d person can come and get out of the house even if its locked.

now imagine a 2d person living in a 2d house.then a 3d person who is taller than 2d's house can come in and get out even if its locked.

Similarly a 4d person can come into the house of a 3d person even if its locked,ie he comes in before the house is locked using time machine.

hope this explains something.

and look at this, a 2D cube is here (http://4.bp.blogspot.com/_WqfT2khXBLo/R19U_Xzl6mI/AAAAAAAAAQI/tC3S3h2W18g/s320/cube2d.bmp)
a 3D cube is here (http://www.gotoandplay.it/_articles/2004/07/3dCube/cube.gif)
But 4D is ether this (http://nodebox.net/code/data/shared/2007-05-31-00-23-43_tesseract.png) or this (http://robertinventor.com/software/virtualflower/virtualflower/hyper_cube_hyper_perspective.gif) or it could even be this one (http://i.ytimg.com/vi/GHeFcVduIzk/0.jpg)

The only thing is- I don't see how a tesseract (whatever its called) is 4D because it still looks like its a 3D figure.

because it has more that 3Dimentions lol. and did my advise help?

I think what 4D is is that its a 3D figure that changes when you look at it from a different angle or changes over time (so then it makes sense now that i put it my way)

Lol, but stay on the MATH topic.

Googling what 1D, 2D, 3D, and 4D may help :D

Heres a poem i made up about it.....

1D is the shallowest of all
Single lines drawn stand tall.
2D at least now with this
A square can be formed oh bliss.
3D now this we get a cube
Woooo we creating now dude!!
4D i guess we adding sound
and textures that us surround.
5D well if it were to exsist
our thoughts feelings are added to the list!!!

anyone like. DOES EVERYONE GET IT NOW????

That's not 4D, that's just a really elaborate 3-dimensional object.

Here, think of it like this, the 4 dimensions are a way of pinpointing what area objects take up in the universe. To know this, you'll need to know the length, width, and depth of the object, those are the 3 dimensions we're familiar with. But along with that, you'll also need to know the area in time in which it exists, because the object will take up a different area in different places in time.

But that's just if Einstein's theories on time are correct, it's a lot of guesswork. Hope I somewhat explained it :)

Yeah- I guess I sorta was right about Space and Time being 4D, but I have to give it to ya- you explained it the best. But I Still wonder if there is a 5D and so on. That would make things really complicated. Infact, it might be so complicated maybe it's hgiher than Algerbra II... all well. So much for that idea. :P

Plagerism doesn't get enough attention anymore. People just copy and paste- but then the whole MLA citation thing takes FOREVER. ughhhhhhhhh (in a frusterated sigh)

It does exist. It's either a simple dot or a straight line. Emphasis on straight- it does NOT bend- though it can go on forever in either one or both directions.

@SuperMonkey- thats off topic man. WAAAAAAAY off topic. Since when does a dead guy (King of Pop [I was sick of hearing that title on the news]) Has to do with dimensions or what we're talking about?

Technically, all units of measurement go on infinitely both ways (larger and smaller), thus, all known objects in the world are 3D, so both 2D and 1D can not exist in this universe. 2D objects are strictly hypothetical and used for math and science equations.

A 1D object has no practical use anywhere, so it'd be rare to see it used hypothetically, let alone actually existing.

Why here- It makes sense here If I explain

1D Just a Line
2D- The Lines connect and bend to make shapes
3D The shapes combine to make an object that has legnth- width, and depth.

Fair enough, I guess for subjects like graphing and quadratics 1D objects are used, but the fact that they are 1 dimensional is not important to anything.

Calling objects "1 dimensional", or "2 dimensional" is misleading. All known physical objects in the universe can be measured with 4 different dimensions. 1D, 2D, and, to a certain extent, 3D objects do not exist.

Very True indeed. But lets put this in a real life explanation- What about an Computer Hard Drive? It's 3Demensional- but what about the curves, shades, and the objects and machines within? Is it 3D or 4D since it's being used by me right now?

We do not know how 4D shapes look.
It has been alot of dreams to figure it out.
Personally, I think ghosts would come from the 4th dimension, as we cannot see them completely, as we only see them in 3D, and we cannot touch them, that's their shadow.
We also know the Nets that are 3d shapes that move in ways we can't imagine to make Hypercubes, Tesseracts. Etc.
2D only has 4 directions... Forward, Backward, Left, Right, but the other one is Height.
3D has all of those.
4D Well... Let's just say it has another direction.

Here is a 0D shape:
.
1D:
----
2D:
____
| |
|__| Square
3D:
I can't draw one but you know how they look.
But 4D...
We know the shadow.

For explained reasons, if we were 2D (Thank god we're not), and let's say a 3D apple shows up, we only see the shadow of it, and wouldn't be able to visualise it.

THat's all from me.

Tesseract or hyper cube.

4D is suppost to be an object, that changed it's shape whenever you look it from different direction.

Just search 4D in Youtube, and it will show you more better than a picture :D

Actully I've dont alot of surfing on youtube and have made games about 4-D shapes i think i frankly know alot about it. The shadow of a hypercube is a wierd one, but you can draw it. The most impressive instance of a 4-D object is when you see an animation of 1. One of my projects "the tessersect" Was never made but was going to be a cy version of a hypercube. My game "portal" also kind of does that. The original idea is by J-Pwn but the way that can exist is because of the existance of a hypercube or "tessersect" There is lots of information about this however, it is all theoreical. The idea of a hypercube is an inifinite amount of cubes adjacent to eachother. To explain the demensions, let us imagine an infinite plain. It is only a plain and goes on forever. The plain can tilt back and forth however need be and the inifinte amount of possible postitions for the infinite plain creates a circle. Now We intersect another infinate plain with it. It can tilt forward or backwards any way possible. The resulting amoutn of infinite solutions of both infinite plains create a sphere. Now of course, there are no other possible intersecting infinite plains that we can see. Lets intersect another plain with it. Lets call it "time" This is not refering to forwards and backwards but the infite solutions of the infinite plains at any possible time. The result creates my game "collapsing hypercube" sequal to "where am i" or so is the theory. If you wantr to know more about this, search online.
