The Alternation Between Unitary Evolution And State Reduction Viewed Through Systemic Functional Linguistics

Penrose (2004: 528-9):

I denote Schrödinger evolution by U and state reduction by R. This alternation between these two completely different-looking procedures would appear to be a distinctly odd type of way for a universe to behave! See Fig. 22.1. 

Indeed, we might imagine that, in actuality, this is an approximation to something else, as yet unknown. Perhaps there is a more general mathematical equation, or evolution principle of some coherent mathematical kind, which has both U and R as limiting approximations? My personal opinion is that this kind of change to quantum theory is very likely to be correct… . However most physicists appear not to believe that this kind of route is a fruitful one to follow.

From the perspective of Systemic Functional Linguistic Theory, the alternation between U and R is "an approximation to" the alternation between quantum potential (when no observation is made) and an instance or quantum potential (when an observation is made).

In this view, it is the interpretation of quantum theory that needs to be changed, not quantum theory itself.
