BACETA V, Jesús F. Physical need and possibility: through Kripke’s mirror and what Kuhn found in there. EPISTEME [online]. 2010, vol.30, n.1, pp.01-10. ISSN 0798-4324.

The modal operators of the physical need and possibility are coded as notions originated in terms of the classical modal homonymous. The mutual definition of the new physical modal notions is herein demonstrated. By using Kripke’s semantics, the validity of the inter-definition is proved. It is created a Kripke’s model as application, in which the relation of accessibility is un­derstood as a relation between pairs of scientific choices explaining the same phenomenon. In this model, the alternative theories are particularly considered: Aristotle-Ptolemy’s geocentrism; Tycho Brahe’s geocentrism and Copernicus, Galileo and Kepler’s heliocentricity. To end with, the proposal of immensity between Kuhn’s theories in Kripke’s wonderland is discussed thereof.

Palabras clave : Modal operators; geocentrism; heliocentricity.
