Abstract
It is easy to take the existence of vision for granted. We are bathed in light that can tell us much about our surroundings, so it is not surprising that we exploit it and that few animals are blind. Yet seeing depends on the coincidence of three apparently quite unrelated properties of just over one octave of the electromagnetic spectrum from about 320–740nm.Keywords
