Sultan Technikon, Durban, South Africa, 1995."The nature of light is only describable by enumerating its properties and founding them on the simplest possible principles. As these principles transcend our ordinary experiences, they must be cast in a purely logical, that is to say, mathematical form. But that is never enough, for, though logic tells us what deductions must be right, it does not tell us what will be interesting, and so gives no guidance as to the direction the theory will take. In choosing this direction, much help is derived from analogies and models which are often loose and incomplete but without which no proper understanding of the subject can be acquired. We shall, therefore, describe, largely by means of analogies, the behaviour of light and this is the 'real' nature of light. "185 penLightingThesishttps://doi.org/10.51415/10321/2731
