# Dimension vs. Dimensionality

Published: Dimensionnoun

A single aspect of a given thing.

Dimensionalitynoun

The state or characteristic of possessing dimensions.

Dimensionnoun

A measure of spatial extent in a particular direction, such as height, width or breadth, or depth.

Dimensionalitynoun

The number of dimensions something has.

Dimensionnoun

A construct whereby objects or individuals can be distinguished.

Dimensionalitynoun

the spatial property of having dimensions;

‘all matter has dimensionality’;

Dimensionnoun

(geometry) The number of independent coordinates needed to specify uniquely the location of a point in a space; also, any of such independent coordinates.

Dimensionnoun

(linear algebra) The number of elements of any basis of a vector space.

Dimensionnoun

(physics) One of the physical properties that are regarded as fundamental measures of a physical quantity, such as mass, length and time.

‘The dimension of velocity is length divided by time.’;

Dimensionnoun

(computing) Any of the independent ranges of indices in a multidimensional array.

Dimensionnoun

An alternative universe or plane of existence.

Dimensionverb

(transitive) To mark, cut or shape something to specified dimensions.

Dimensionnoun

Measure in a single line, as length, breadth, height, thickness, or circumference; extension; measurement; - usually, in the plural, measure in length and breadth, or in length, breadth, and thickness; extent; size; as, the dimensions of a room, or of a ship; the dimensions of a farm, of a kingdom.

‘Gentlemen of more than ordinary dimensions.’;

Dimensionnoun

Extent; reach; scope; importance; as, a project of large dimensions.

Dimensionnoun

The degree of manifoldness of a quantity; as, time is quantity having one dimension; volume has three dimensions, relative to extension.

Dimensionnoun

A literal factor, as numbered in characterizing a term. The term dimensions forms with the cardinal numbers a phrase equivalent to degree with the ordinal; thus, a2b2c is a term of five dimensions, or of the fifth degree.

Dimensionnoun

The manifoldness with which the fundamental units of time, length, and mass are involved in determining the units of other physical quantities.

Dimensionnoun

the magnitude of something in a particular direction (especially length or width or height)

Dimensionnoun

a construct whereby objects or individuals can be distinguished;

‘self-confidence is not an endearing property’;

Dimensionnoun

one of three cartesian coordinates that determine a position in space

Dimensionnoun

magnitude or extent;

‘a building of vast proportions’;

Dimensionverb

indicate the dimensions on;

‘These techniques permit us to dimension the human heart’;

Dimensionverb

shape or form to required dimensions

Dimensionnoun

a measurable extent of a particular kind, such as length, breadth, depth, or height

‘the drawing must be precise in dimension’; ‘the final dimensions of the pond were 14 ft x 8 ft’;

Dimensionnoun

a mode of linear extension of which there are three in space and two on a flat surface, which corresponds to one of a set of coordinates specifying the position of a point.

Dimensionnoun

an expression for a derived physical quantity in terms of fundamental quantities such as mass, length, or time, raised to the appropriate power (acceleration, for example, having the dimension of length × time⁻²).

Dimensionnoun

an aspect or feature of a situation

‘we must focus on the cultural dimensions of the problem’;

Dimensionverb

cut or shape (something) to particular measurements.

Dimensionverb

mark (a diagram) with measurements.

Dimension

In physics and mathematics, the dimension of a mathematical space (or object) is informally defined as the minimum number of coordinates needed to specify any point within it. Thus a line has a dimension of one (1D) because only one coordinate is needed to specify a point on it – for example, the point at 5 on a number line.
