The author of this paper tries to introduce the concept of RAS as a unit of communication. RAS is the smallest constructing unit of a message and it produces the meaning of a message in the receiver. Since RAS is neither objectively nor directly observable, the sciences of physics and biology are utilized in the study of this concept. Though communication science, physics, and biology seem, on the surface, three distinct categories, there are certain similarities as well as commonalities in the basics of these branches. These commonalities have contributed to the identification and conceptualization of RAS as the unit of communication. The author is of the opinion that hard sciences provide a proper route to understand the concept of RAS, and has found certain features and characteristics which provide a proper ground for the analysis of the communication unit. Some of these features are equilibrium in communication systems (on the basis of two factors: ‘need’ and ‘density’), similar linear relationship with the environment, active and passive transference, distinct responsibility in communication units, concordance with the law of light refraction, superimposition with a different RAS field, information reflection phenomenon, simulation and multiplication, mutation, relationship with a former RAS as the origin of a new formation, dialectic of order and disorder, the formation of a RAS chain or network, the internal forces which are important in the effectiveness of a message on the audience, effectivity and susceptibility cycle, effectivity index, the mutability of energy from one form to another, RAS wavy movements, and refraction states.
