Three Dimensional Space
The property of the space in which we live and move that indicates
motion can take place in three mutually perpendicular directions.
This is often expressed with three-dimensional
Formally, saying a space has three dimensions means
that you can find three vectors in the space for which
none is a linear combination of the other two. In addition, in
any set of four vectors one of them can be written as a linear
of the other three.
