The Reciprocal System of theory Overview
The Reciprocal System of physical theory was introduced in the 1959 publication, The Structure of the Physical Universe, by Dewey B. Larson.
This overview is going to cover some of the basic concepts of the theory and how it is simply a modern interpretation of the ancient, Taoist philosophy of yin-yang. It proposed the Universe is divided into two sectors, a spatial, material sector (yang) and a temporal, cosmic sector (yin), that are connected together under a concept described as motion, the ratio of space to time. Like yin-yang, the space and time aspects of motion can never be separated, so the the Universe, and everything in it, is Nothing But Motion.
