Frequently the most interesting part of a spectrum is what's left outside of it. When we speak of the color spectrum displayed in a rainbow what we are referring to is the tiny stretch of electro-magnetic wavelengths our eyes are able to detect. The larger spectrum ranges from x-rays, so small and energetic they can punch through the surface of solid objects, to radio waves so large and lazy that they unnoticed through solid earth. And what is left out of this spectrum? Well unlike color this spectrum is based on a mathematical relation, wavelength times frequency equals the speed of light, and so there is no wave that cannot be placed upon it. But, it is not yet determined where in actuality the waves stop. Just how far this spectrum goes is an open subject in theoretical physics, and so again we find the true fascination just outside the edge.

This as true of politics as it is in physics. In this country we are accustomed to seeing the spectrum of opinion regularly presented to us in our elections. The liberal conservative spectrum that runs from Democrats to Republicans. So accustomed that it can come as a shock to realize that in some countries our politics seems as narrow a space as color is when compared against the full richness of the electromagnetic field. It is always important to ask what lies beyond the edge of the familiar.
