It should be understood that, just as the Newtonian program of research is a system of theory, under which many physical theories are developed to explain nature in terms of the fewest number of interactions among the fewest number of particles, so too Larson's Reciprocal System of physical theory accommodates various theoretical approaches to explain nature in terms of scalar motion.

So far, there are three different approaches. One is the approach of Ronald Satz, who continues to develop Larson's original work. Another is the RS

^{2}, which is pursued by Bruce Peret and Gopi, and then there is my approach, being developed at the LRC.

To keep this understanding as clear as possible, I refer to Larson's SYSTEM as the Reciprocal System of Physical Theory (RST), and a given RST-based theory as a Reciprocal System theory or RSt.

The fundamental differences between these three RSt approaches is found in the way they treat the uniform progression of space and time, the scalar motion posited by the fundamental postulates of the RST, the foundation of the new system.

In my RSt, the deviation from the uniform progression that creates physical entities is a 3D oscillation, which replaces Larson's 1D oscillation leading to the photon. In my RSt, the photon is created when a 3D space oscillation combines with a 3D time oscillation. These entities are named, but I will refer to them here as the S and T entities.

Because of the reciprocal nature of space and time that the RST posits, The Ss progress in time only, while the Ts progress in space only, making it possible for them to collide and combine, forming an S|T combo that progresses both in space and time.

When these S|T units combine in two or more, as parallel combos. like sticks in a bundle, they form bosons, and when they combine in three or more, as triplets in a triangle, they form fermions. These are identified with the bosons and fermions of the first family of the legacy system of theory (LST) community's standard model of particle physics (SM), with the exception of the HIggs boson.

The major advantages of this approach are that it is consonant with the postulates of the RST, and it is formulated mathematically, something for which students of Larson often longed to see in closed form.

As requested earlier in the General Discussion topic "Dimensions in the Reciprocal System," I will explain the mathematical formalism of the S|T units, or preons, in a subsequent post.
