The universe is
an all encompassing, dynamic physical system. It is comprised of matter and
energy, all of which interacts through four basic forces. Within this physical
system, life exists. The piece of this universe within which any particular
variant of life can be found, we’ve called an ecosystem. Thus, within any ecosystem, as we have thus far
discussed them, the four basic forces apply. This is why we have referred to
ecosystems as physical ecosystems. We do this in order
to be able to unambiguously introduce an analogue extension to such ecosystems
that we have termed a social ecosystem in which, in addition
to basic physical interactions, extended rules exist that allow for the
initiation and control of more varied interactions.
We will find,
when we examine them in more detail, that the rules of the social ecosystem can
change among the various systems; it is not a given that the same rules apply
everywhere as they do for physical ecosystems. Whether we are discussing the
basic laws governing the forces in a physical ecosystem or the rules that
govern a social ecosystem, these laws or rules form the central elements of
policy within the respective ecosystem. While we tend to think of policy as
being a mutable set of rules, in fact the pairing of variable social rules with
the immutable laws of nature show us the full range of characteristics that we
want to model in the form of a policy infrastructure.
Any two or more
physical entities can interact by way of the four basic forces: the strong
nuclear force, the weak force, electro-magnetic force and gravity. The range of
these forces is infinite, but their magnitude as a function of distance varies
such that each tends to dominate interactions within vastly different domains
of separation of the interacting entities. The strong force dominates at
separation distances on the order of the size of an atomic nucleus while the
weak force dominates at much smaller than nuclear distances. Electro-magnetic
forces dominate over distances that are familiar to humans in their everyday
lives. Gravity dominates over the range of distances from everyday life to
inter-galactic interactions. At every level, there are characteristics of the
various forces that lend variability to the result of interactions;
specifically, quantum mechanical effects in the basic forces and variability in
the initial conditions of interactions. That is, because of our lack of
precision on the initial states of the interacting entities and because quantum
mechanical effects are modeled with a statistical distribution of outcomes, it
is impossible for us to predict exactly the result of any specific interaction.
Hence, the old homily that says “Doing the same thing over and over again and
expecting a different outcome each time is the definition of insanity.” might
be taken with a grain of salt. Not only can repetition of interactions lead to
different results, quantum mechanics grounds this uncertainty into the very
fabric of nature. On the macroscopic scale of human interactions, repeatability
of observable results is considerable, but billiards is still a game requiring
great skill and they continue to play best four out of seven games to determine
the winner of the World Series in baseball each year. As we noted at the
beginning of this chapter, what the same thing is (that we do over and over
again) requires case-by-case definition with extreme precision of the initial
conditions, with acknowledgement that even then we can’t know the outcome for
sure.
Interactions
within a physical ecosystem involve only basic physical laws and the
characteristics and capabilities of resident species to exploit the mechanisms
of physical systems. For example, the most elementary interaction between two
entities within a physical ecosystem is bringing them into physical contact.
Among the basic forces, the force of gravity is infinite in extent, meaning
that an attractive force is constantly at work to bring various entities into
physical contact. The initial conditions of motion of the entities determine
whether they ever actually touch. Going a bit further afield, we might consider
the situation of living entities brought into close physical
