GONZALEZ, Carlos Gustavo. David Hilbert e o Axioma de Arquimedes: entre a geometria e a física. Educação e Filosofia [online]. 2015, vol.29, n.57, pp.343-379. ISSN 1982-596x.  https://doi.org/10.14393/REVEDFIL29n57p343.

The relationship between geometry and physics in the work of Hilbert is analyzed through the case of the axiom of Archimedes. Starting with geometrical and formal issues (in particular, the definition of non-Archimedean models used for proving its independence), following with Hilbert conception that the physics is an empirical science, finally it is studied the Hilbertian statement that the axiom must be empirically confirmed. In this sense, he conceives an empirical statement of the axiom which must be confirmed by experiment. This statement arises three kind of questions. First, whether it actually is an empirical statement or a methodological rule which is not able to test. Second, whether it is a suitable interpretation of the axiom. Third, how can be created tests in relation to the empirical statement. Besides the fact that the two initial questions are difficult, the case of the third is worst, because, as far as I know, nobody proposed such a test, i.e. how can be designed well defined experiments to confirm the empirical statement (different, for example, of the case of the measurement of the sum of the angles of a triangle, performed by Gauss). The criticisms of Leo Corry and Michael Stöltzer are analyzed too, in particular the questions about adequacy and verification of the empirical statement. Furthermore, it is emphasized the relevance of the distinction between the concepts of measurement, inherent to the Archimedean axiom, and the one of the continuity (in Dedekind's sense), based upon the criticism of Sommer on the Foundations of Geometry of Hilbert.
