The dimension of a vector space is the number of vectors in any basis of the space. Examples: R3 has dimension 3 P3 has dimension 4 (with basis {1,x,x2,x3}) C has dimension 1 when viewed as a vector space with complex scalars, but it has dimension 2 if it is viewed as a vector space with real scalars (with basis {1,}).
Latin dimensio, a measuring -- there are four known dimensions, the three space coordinates of length, width, and depth, along with the fourth dimension of time in the theory of relativity. The space-time continuum is a four-dimensional continuum with four coordinates, the three dimensions of space and that of time, in which any event can be located.
1. A division of the universe. The psi concept envisions a physical world and an ethereal realm each of unknown number of strata. The evidence about the ethereal suggests many spiritual planes, which are referred to, at times, as dimensions, or levels. 2. Measurement characteristics about the size of things, such as, the aura, the spirit body.
an independent axis or direction in space or spacetime. The familiar space around us has three dimensions (left-right, back-forth, up-down) and the familiar spacetime has four (the previous three axes plus the past-future axis). Superstring theory requires the universe to have additional spatial dimensions.
measure in one direction; specifically: one of three coordinates determining a position in space (X, Y, Z)
A universe or realm containing space, time, matter, and energy.
A "space". A dimension's limits are defined by normal physical movement (assisted or unassisted). Reality as we know it, from Earth to the edge of the universe, is one dimension.
one of three cartesian coordinates that determine a position in space
