What is 4D
Posted 15 July 2012 - 02:52 AM
EDIT: from what's in the wikipedia page, i think the third dimension is 3 because we have horizontal, vertical, and depth to find a specific point. 2d is 2 because there is only horizontal and vertical. with the fourth dimension...there's a fourth but i haven't quite grasped that concept yet.
also, by looking at the math, it makes sense, but in a real life situation it's a little more confusing without the CG graphic

im no physcists but that is what i was taught in college physics in the 90s
In physics and chemistry, plasma is a state of matter similar to gas in which a certain portion of the particles are ionized. Heating a gas may ionize its molecules or atoms (reduce or increase the number of electrons in them), thus turning it into a plasma, which contains charged particles: positive ions and negative electrons or ions. Ionization can be induced by other means, such as strong electromagnetic field applied with a laser or microwave generator, and is accompanied by the dissociation of molecular bonds, if present

In mathematics, four-dimensional space is an abstract concept derived by generalizing the rules of three-dimensional space.
There are different discipline definitions for four-dimensional space.
In Algebra, its generated by applying the rules of vectors and coordinate geometry to space with four-dimensions.
In Physics, space and time are unified in a four-dimensional "Minkowski" continuum called spacetime, whose metric treats the time dimension differently than the three spatial dimensions.
Thus, spacetime is not a Euclidean space. Minkowski spacetime is the mathematical setting in which Einstein's theory of special relativity is most conveniently formulated.
In layman terms, three ordinary dimensions of space are combined with a single dimension of time to make a four-dimensional manifold for expressing spacetime.
Hope this helps clear any confusions. All the Best~

Man has found that 3 dimensions give an accurate and friendly representation of space. Heck, you can even represent an object's coordinates by using 1 dimension only, in other words, we live in 1 dimensional (curvy) universe.
4th dimension could be time if you want it to, or it could be a dimension we cannot comprehend. Remember that these are all theories and you can manipulate them as you wish, there are many uses for dimensions, but it is globally accepted that the first 3 dimensions are x, y and z and that the fourth dimension is (generally) time.

There is nice ways and there are utter dickhead ways to say things^^^^^^
So who are you airwavez to label others as confused? After all, your behind a computer screen hiding behind a screen name blabbing whatever comes to your noodle like you got a license to judge whomever.
Its better to remain silent and be assumed the fool, then to open your frontal fuck hole and remove all doubt. Maybe next time you will learn to be nice to others Airwavez?????
