Definition

The Elementary Field, from which all the various known fields derive, is the passive, receptive aspect of the fundamental entity, the Primary Source. It is the substrate and the object of the Events that form Reality.

Common definition

In physics, a field is a defined entity in every point of space, or more generally of space-time.

Fields are represented mathematically as scalars, vectors, tensors and spinors. For example, the gravitational field can be modeled as a vector field where a vector indicates the acceleration exerted on a mass for each point. This intuitively, even if the gravitational field indicates the force acting on a unitary mass and not an acceleration (a book placed on a table does not undergo any acceleration but a force field). Other examples may be the temperature range or the atmospheric pressure range, which are often illustrated by isotherms and isobars by connecting the points that have the same temperature or pressure respectively.

From this point of view a field can be more simply defined as the set of values ​​that a given physical quantity, scalar or vector, assumes in space. Helmholtz's Theorem is fundamental for understanding fields as it provides a class of parameters that uniquely determine them.

In the case of a force field, such as the gravitational field and the electric field, the concept of field is closely correlated with that of interaction at a distance. (Link to Wikipedia page: Field).

Description

From the dynamics of the Elementary Field an the Elementary Action emerges the physical space and time, as direct manifestations of two of the fundamental emerging properties of the Primary Source: Spaciality and Temporality, the other fundamental property being Causality.

It can have two fundamental states:

  • Non Existence - Nothingness: state characterized by absence of causal perturbative action of the Force, absolute homogeneity of the parameters that characterize the Field
  • Existence: under the causal perturbative action of the Force, the Field undergoes a transition of state, from the condition of non existence to the existence, from nothingness to the Elementary Action, the set of the Elementary Events, the most elementary form of existence.

Two simple scheme that links the Field to the Force and to the Action:

Fundamental Force (Agent) << Action of the Force on the Field and reaction of the Field on the Force >> Elementary Field (Acted) => Events (Action).

Formation: Ontological aspect: Entity <--Inner interaction--> Entity --Creation--> Phenomenological aspect: Events (Action) --Evolution--> Dynamical aspect: Relations, Processes --> Information, Structures, Forms, Universe.
