Abstract
Euclidean geometry, statics, and classical mechanics, being in some sense the simplest physical theories based on a full-fledged mathematical apparatus, are well suited to a historico-philosophical analysis of the way in which a physical theory differs from a purely mathematical theory. Through a series of examples including Newton’s Principia and later forms of mechanics, we will identify the interpretive substructure that connects the mathematical apparatus of the theory to the world of experience. This substructure includes models of experiments, models of measurement, and modular connections with partial theories. It evolves during the life of a theory as physicists learn how to apply it in various contexts. It should nevertheless be regarded as an integral part of a genuine physical theory since the theory would otherwise degenerate into pure mathematics.

Notes
Famous expositions of the semantic view include Suppe (1974, 1989), van Fraassen (1980), and Giere (1988). The structuralist variety of this view (Sneed, 1971; Balzer et al., 1987) is more concerned with interpretive substructures (see Torretti, 1980, Chap. 3). For a recent critical overview of received conceptions of scientific theories, see French (2020).
For a philosophical understanding of mechanics, Ronald Giere’s variety of the semantic view is more relevant than others, for it is based on an inspection of the structure of mechanics treatises. His remarks on the role of theoretical models and exemplars anticipate some of what I have to say on interpretive schemes in the same context (Giere, 1988, Chap. 3). Also relevant are van Fraassen’s comments on Atwood’s machine, regarding the necessity of theory-dependent models of measurement (van Fraassen, 2012, pp. 776–777). However, modular structure is completely ignored in these texts.
Vorms (2011).
For an insightful criticism of these intermodular relations, see Wilson (2013). In “the intricate interwebbing we call ’classical mechanics’,” Mark Wilson sees “as effective a grouping of descriptive tools as man has yet assembled” (ibid. p. 104).
On the conceptual importance of asymptotics, see Batterman (2002).
For details and justifications, see Darrigol (2008, 2014, Chap. 9). This definition of theories does not match any of the options considered in French (2020) (syntactic, semantic, representational, fictional). Indeed, these options are too static and too holistic to include the evolutive, modular character of theories. Hopefully, the proposed definition eludes Steven French’s pessimistic conclusion that “there are no such things as theories.”.
For a telling example of such attention, see Cat (2001).

Duhem (1906, p. 308): “La science physique, c’est un système que l’on doit prendre tout entier ; c’est un organisme dont on ne peut faire fonctionner une partie sans que les parties les plus éloignées de celle-là entrent en jeu, les unes plus, les autres moins, toutes à quelque degré.”
This is a good example of Galilean idealization as discussed in McMullin (1985); nature is being “carved at its joints.”.
Clearly, Newton does not regard statics as a defining module of mechanics (he rather sees it as specializing module), but many of his followers did so, for good reasons (in particular, the second law thus acquires a more direct empirical content). See Darrigol (2020).

van Fraassen (2012, pp. 782, 783) writes: “The crafting of a relationship between theory and phenomena is an interplay of theory, modeling, and experiment during which both the identification of parameters and the physical operations suitable for measuring them are determined” as well as “Empirical grounding is this process of simultaneously, harmoniously extending both the theory and the range of relevant evidence.” The details of this process are left to the reader’s imagination.
“In the beginning was the Act.” Thus speaks Goethe’s Faust in a parody of the biblical “In the beginning was the World.” Helmholtz liked to cite this verse to capture the essence of an interactive theory of perception.
