Making progress in that direction. We have two factors for measuring conceptual systems (plans, models, theories, policy models, program theories). One factor is the "simple" Complexity (number of concepts within the conceptual system). Another factor is the Systemicity (a ratio describing the causal interconnectedness of those concepts - from I.P.A.).
A simplified version relating to strategic plans is here on p. 5:

Here, conceptual systems of physics would be in the upper left hand quadrant - having a Systemicity of 1.0 (amenable to algebraic manipulation) but a typically low Complexity (certainly useful for understanding and predicting change in the world of physics, but probably not sufficiently complex for use in the social sciences:

Could you suggest what a fourth factor might be?
Thanks,
