Ok, so on a booring evening, entertainment came in the form of the "random article" on wikipedia. I came to the dimension entry, where I saw something called a tesseract, a figure that represents the 4th dimension.
So, answer me this in the terms a soon-to-be 11th grader 'd understand.

If 0D is a point, 1D is a line(segment), 2D is a plane, and 3D is space... What is 4D? (or a tessaract, whatever) I'd actually read the wiki page, but 'tis a bit confusing for someone at my level of education but is nonetheless interested in this sort of stuff.

OD = 2^0 = 1pt ( a single point)
1D = 2^1 = 2pt (each end of the line)
2D = 2^2 = 4pt (each corner of a square)
3D = 2^3 = 8pt (each corner of a cube)
4D = 2^4 = 16pt

Think of it like this.

You have a point (0D) you stretch it in a direction...you now have a line (1D), now, you stretch that line in another direction, you now have a square (2D), you now stretch each point of that it in yet another direction and end up with a cube (3D)...and the cycle continues.

You take it, and stretch every point into another dimension...

There was also a very horrible movie made by that name.

It had nothing to do with mathematics at all. Not that it would have been any less horrible if it did.

Actually, come to think of it, the movie was relevant to mathematics ... in that it created new dimensions of horrible, awfull, uninteresting, waste 2 hours of your life and cry in your beer, moviemaking. So I guess the name was appropriate. This movie opened my mind to new dimensions of horribility, to coin a new word. It was that bad.

Gabriel, if you check out the wiki page, you'll see some patterns that will mesmerize anyone who takes home one of your quilts. Either that or drive them bonkers.

Hypnotic quilts, anyone?

It is. That's just an attempt to model it in a two-dimensional surface.

Oh.

My accepted 2-D model of time is a clock. That's a little easier to think of.
