Its All about Pj Problem Strings - 7 Spaces Of Interest and their associated Basic Sequences; 7 Pj Problems of Interest (PPI) and their Alleles (A)
The word system is ubiquitous in design and analysis parlance. Basically, a system is the space under consideration. Everything outside the considered space is called its surrounding. Almost always, the space is occupied by matter. A system may be as simple as an atomic space or as immense as the entire Universe. The definition of a perimeter inorder to establish the space to be considered is a containership problem and any problems of interest in the space being considered are definitely Pj problems.
The number of systems that can be defined is infinite: atomic systems, molecular systems, ecosystems, respiratory system, digestive system, cardiovascular system, health systems, political systems, economic systems, social systems, etc. Fortunately, the grouping of systems is finite. Any system with respect to the definition of its containership, explicitly belong to one of the following 7 space groups:empty space
single-matter static space
single-matter dynamic space
multi-matter static space
multi-matter dynamic space
multi-matter multi-static spaces
multi-matter multi-dynamic spaces
And the problems of interest in it, belong to the Pj problems group.
Systems designs and analyses are in essence SiPj designs and analyses (where Si is the ith space under consideration and Pj is the jth problem of interest in the space).
The system parlance is opaque in the sense that it does not enunciate the basic concepts of a system. The concepts of space, matter and dynamism are familiar and can easily be explained even to unseasoned thinkers. So are the members of the Pj problems group.
