  1. Dimension

    In physics and mathematics, the dimension of a 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 because only one coordinate is needed to specify a point on it. A surface such as a plane or the surface of a cylinder or sphere has a dimension of two because two coordinates are needed to specify a point on it. The inside of a cube, a cylinder or a sphere is three-dimensional because three coordinates are needed to locate a point within these spaces. In physical terms, dimension refers to the constituent structure of all space and its position in time, as well as the spatial constitution of objects within—structures that correlate with both particle and field conceptions, interact according to relative properties of mass—and are fundamentally mathematical in description. These, or other axes, may be referenced to uniquely identify a point or structure in its attitude and relationship to other objects and occurrences. Physical theories that incorporate time, such as general relativity, are said to work in 4-dimensional "spacetime",. Modern theories tend to be "higher-dimensional" including quantum field and string theories. The state-space of quantum mechanics is an infinite-dimensional function space.

Chambers 20th Century Dictionary

  1. Dimension

    di-men′shun, n. usually in pl., measure in length, breadth, and thickness (the three dimensions of space): extent: size.—adjs. Dimen′sional, concerning dimension (one-dimensional, two-dimensional, three-dimensional space = space of one, two, three dimensions); Dimen′sioned, having dimension; Dimen′sionless.—Dimension work, masonry in stones of specified size.—Fourth dimension, an additional dimension attributed to space by a hypothetical speculation. [Fr.,—L. dimensiodimetīri, dimensusdi(= dis), apart, metīri, to measure.]
