To master communication, one must understand it. Communication, in essence, is the shift of a particle from one part of space to another part of space. A particle is the thing being communicated. It can be an object, a written message, a spoken word or an idea. In its crudest definition, this is communication.
Duplication is the act of reproducing something exactly.
The formula of communication is cause, distance, effect, with intention, attention and duplication with understanding. The definition and formula of communication open the door to understanding this subject. By dissecting communication into its component parts, we can view the function of each and thus more clearly understand the whole. Any successful communication contains all the elements shown here. Any failure to communicate can be analyzed against these components to isolate what went wrong.
