The word Dimension can refer to shapes such as 2-dimensional (2d) shapes and 3-dimensional (3d) shapes. A simple example of a 2d shape is a square whilst its 3d counterpart is defined as a cube. Dimensions can be better explained using axis. On a 2d coordinates grid we have only an 'x' axis and a 'y' axis whilst on a 3d grid there is a third 'z' axis. Let's count up how many axis we have on both grids. On the 2d grid we have 2 axis, hence the definition 2-dimensional. On the 3d grid we have 3, hence the definition 3-dimensional. Humans can see only a limited number of dimensions. We mostly see 3-dimensions as some faces of opaque shapes are often hidden unless we change our viewpoint. Then again even if we change the angle at which we see something, some of the faces we could see before are then hidden. This is a simple study of dimensions and should be referred to before moving on to more complex dimensional studies.

ganesh, you are well meaning and share an interest in the peculiarity possesed by certain numbers. But I take an interest in 0, the Alpha and Omega of all numbers. A number that alone signifies nothing but when merged with other numbers signifies much more. It is odd but true and we all know of these facts. Face it ganesh, 0 is awesome:D

Why thank you. I will be sure to enjoy myself.
There is much I have to say and show.:cool:
