Space is a three-dimensional continuum. The positions of an object at rest can be described by three numbers (co-ordinates) x, y, z. Similarly, the world of physical phenomena is naturally four-dimensional in the space-time sense. For it is composed of individual events, each of which is described by four numbers, namely, three space co-ordinates x, y, z and a time co-ordinate, the time value t.
Three SPACE co-ordinates:
*X=25ft
*Y=35.5 Degrees N
*Z=106 degrees W
and the TIME co-ordinate
*t=8:36 PM
