One would suspect that this manner of changing EMMI would occur
between every object, and that no two objects would maintain the exactitude
of the original EMMI. Therefore, each event that represents a transformation
of EMMI by an object records that event as an illustration of the causality
associated with events. An event is depicted in Figure 2.5. An event only
occurs after an object has received input EMMI. An event is observed after
the enactment of the object’s mechanism and an output EMMI has been
released from the object. Events extend boundaries.
Objects and Boundaries
Objects are comprised of matter or energy in ways that manifest as physical
properties, for example, an electron is an object. An object can be anything
physical. Objects can also be anything symbolic, conceptual, relational, or
“intellectual” as long as there is a physical manifestation of whatever form
the object takes (Thurstone 1946). That two physical objects are touching
means some of the constituent objects in one object have explicit physical
contact with constituent objects in another object. It is currently beyond
human skills to engineer two surfaces so that both have a continuous, uninterrupted area of surface contact along the entire length of the zone of
touching. In some circumstances atoms or molecules from one object “drift,”
“migrate,” or adhere to other objects. A mixing of physical constituent objects
of one object with another object does not blur the physical boundary of
either object (unless the objects develop changes in properties or traits). Alien
objects intermingle with other constituent objects routinely (Langford 1971).
If the properties of an object change due to these alien objects then there is
integration. We loosely describe that area or volume of contact as the connection. When two objects are connected we mean that they are joined by such
contact and not be impeded by those spots where no contact exists. The two
