1.3.1 Multidimensional objectsThe problem with spacetime is that it is a four
dimensional object, hence, there is great difficulty in
understanding how it can be imagined using the only three
dimensions available in space. Today, however, these
concepts are often used in other fields like Computer
science. Computer programmers use the idea of
multidimensional memory cell (arrays). One array, is
simply a memory cell in which they can store data. A one
dimensional array, is a row of these cells which makes up
a line. A two dimensional array is many rows aligned next
to one another to make up a plane. A three dimensional
array, is many plane aligned next to one another to make
up a square solid. The pattern here is that, the last
object that has been created is multiplied by the number
of the next dimension, hence, if the array was 3 cell
long, then the three dimensional array is 3x3x3=27 cells.
Consequently, the four dimensional array is 27x3=81
cells, which is the solid formed by the three dimensional
object lined up again along a row this time 3 solids
long. A five dimensional array is then many of these rows
aligned next to one another to form a plane of solids,
and so on. |
