One
lonely view won't do it!
Blueprints
require at least three views. . .
before
complex objects become understandable.
Furthermore:
Dimensionality is not limited
to spatial dimensions. Color perception, for example, could be any
number of dimensions, from one (total colorblindness) to infinity (spectroscopic
color). Normal human color perception is three-dimensional.
Normal bird color perception has a higher dimensionality.
Visualizing dimension higher
than three is a challenge, but it is possible. |

A
thermometer gives one-dimensional information. |
|
Blueprints
and maps ordinarily give two-dimensional information. |
|
However,
blueprints convey the third dimension by showing different views.
Maps can give three-dimensional information with shaded relief or with
contour lines. |
|
|
|
|
|

|
|
|

We
usually plot three-dimensional data on a simple three cooridnate system:
an "x" - "y" - "z" system of three axes all at right angles to each other.
(They are orthogonal.) |
|
|
|
|
|
|
|
|
|
 |
|
|
|
|
|
|
|
|
|
These
are the familiar "x," "y," and "z" axes.
If
we have a fourth independent component to add to the other three, we can
plot it like this: |
|
|
|
|
|
|
|
|
|
 |
|
|
|
|
|
|
|
|
|
Each
position on the yellow line through the origins represents a value of the
fourth variable.
To
add a fifth component, we repeat the process. The entire line of
three-dimensional axes is repeated at right angles, like this: |
|
|
|
|
|
|
|
|
|
 |
|
|
|
|
|
|
|
|
|
This
process can be repeated indefinitely. As the number of dimensions
gets very large, it begins to look, Mandelbrot set-like, like a fractal.
It keeps showing similar detail as we enlarge any portion to see greater
detail.
Man's most powerful problem-solving
tools:
Dimensionality (degrees of
freedom) and its related mathematics is one of these tools. Many
modern science concepts require at least a little understanding of dimensionality.
This is understanding which can lead to some powerful tools. It's
part of the skeletal infrastructure of modern science.
