What Does Yin and Yang Really Mean?
The core dynamic in nature is the conservation of a circle.
Yin and Yang are X and Y, diameter and circumference of a circle. Also known, more technically, and technologically, zero, and-or, one.
Therefore, complementarity is the basis for identity and duplicity is the basis for a unit (any discipline, system). Meaning, zero is one (and vice versa).
This is the basis for the binary system (technology and biology) symbolic, and real. If zero, then one.
