The Scientific Use of Dimensions as Directions

Directions that are mutually perpendicular to each other are called dimensions. The common depiction of individual dimensions on a graph is as an axis lines that show the direction of that particular dimension.

Building dimensions begins ar a point which has of zero dimensions. A point can be expanded into one dimension forming a line of two dimensions. A lined can then be expanded into two dimensions so as to form a plane. Finally the plain can be expanded into three dimensions forming a space of three dimensions.. This process can be continued with out end. Theoretically there is no limit to the number of dimensions. In spite of our existence has only three spacial dimensions any number of dimensions is theoretically possible.

In physics dimensions have been classically used to refer to space however Spacial Relativity added time as a dimension. Cosmological Relativity adds cosmic expansion velocity as a dimension. String theory uses from 10 - 26 dimensions and its child M theory uses 11 dimensions. Mathematically there in no limit to the number of possible dimensions from zero to infinite dimensions. In fact Nth dimensional modeling is useful for dealing with any set of properties as if they were physical dimensions.

While dimensions are primarily used to describe space and time though some physical theories use more than three spacial dimensions specifically string theory. They can also be used to model the distribution of non spacial properties.
