Likewise, it is impossible to measure temperature without using some law that depends upon either phenomenological or statistical thermodynamics. Hence, there are clear-cut instances of observation concepts that apply to unobservable entities, which does not seem acceptable cf.
The pillars of modern physicsand perhaps the most revolutionary theories in the history of physics, have been relativity theory and quantum mechanics. In this regard, theoretical particle physics forms a good example. To an even higher degree, we are unable to observe electrons, molecules, gravitational forces and genes on this narrow understanding of observability.
Carnap is most explicit about the indeterminacy that this doctrine implies. Properties and entities that are observable in the sense of direct, unaided perception did not seem to depend on scientific theories as forces, electrons and nucleotides did. The great push toward the modern concept of explanation started with Galileoone of the few physicists who was both a consummate theoretician and a great experimentalist.
We have seen, moreover, that the formal accounts of theoretical terms work well with a theory-observation distinction that is relativized to a particular theory. As the Scientific Revolution gathered pace, the concepts of matterenergy, space, time and causality slowly began to acquire the form we know today, and other sciences spun off from the rubric of natural philosophy.
Unlike Carnap, Weyl did not characterize the interpretation of theoretical terms by means of model-theoretic notions. Underlying this controversy is a disagreement over specific goals of physical research which was considered crucially relevant to the further course of physical inquiry.
Second, denotationless terms are dealt with along the lines of free logic by Dana Scott This account starts with an initial baptism that introduces a name and goes on with causal chains transmitting the reference of the name from speaker to speaker.
For if there is nothing that satisfies a description, the corresponding expression has no referent. Third, axioms of a scientific theory are not conservative extensions of the observation language since they enable us to make predictions. This move, however, only shifts the problem to applications of another axiom of T.
First, if descriptions of theoretical entities are constitutive of the meaning of corresponding unary predicates, one must wonder what the common core of understanding is that adherents of successive theories share and whether there is such a core at all.
The need for assuming such an interpretation is simply denied. In this regard, theoretical particle physics forms a good example. In fact, all formal accounts of the semantics of theoretical terms are devised to apply to axiomatic scientific theories.A theoretical definition is an abstract concept that defines a term in an academic discipline.
Without a falsifiable operational definition, conceptual definitions assume both knowledge and acceptance of the theories that it depends on. . An Analysis of the Concept of Theoretical Physics PAGES 2.

Logical analysis is in Frege primarily not an analysis of a concept but of its sense. We start by remarks on the scientific and societal context of today's theoretical physics.
