Dimension vs. Dimensionality — What's the Difference?

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.

A measure of spatial extent, especially width, height, or length.

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

Often dimensions Extent or magnitude; scope

An aspect or feature of a situation

Aspect; element

Cut or shape (something) to particular measurements.

The least number of independent coordinates required to specify uniquely the points in a space.

A measure of spatial extent, especially width, height, or length.

The range of such a coordinate.

Often dimensions Extent or magnitude; scope

(Physics) A physical property, such as mass, distance, time, or a combination thereof, regarded as a fundamental measure of a physical quantity

Aspect; element

A realm of existence, as in a work of fiction, that is physically separate from another such realm

The least number of independent coordinates required to specify uniquely the points in a space.

To cut or shape to specified dimensions.

The range of such a coordinate.

To mark with specified dimensions.

(Physics) A physical property, such as mass, distance, time, or a combination thereof, regarded as a fundamental measure of a physical quantity

The state or characteristic of possessing dimensions.

A realm of existence, as in a work of fiction, that is physically separate from another such realm

The number of dimensions something has.

To cut or shape to specified dimensions.

The spatial property of having dimensions;

To mark with specified dimensions.

A single aspect of a given thing.

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

A construct whereby objects or individuals can be distinguished.

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

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

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

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

A universe or plane of existence.

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

To specify the size of (an array or similar data structure); to allocate.

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.

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

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

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.

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

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

A construct whereby objects or individuals can be distinguished;

One of three cartesian coordinates that determine a position in space

Magnitude or extent;

Indicate the dimensions on;

Shape or form to required dimensions
