The concept of a Madelung fluid makes us accept that the matter per se admits at least a description, if not even a physical structure, by ensembles of free Hertz material particles. This chapter elucidates the idea of physical freedom, according to the nonstationary Schrödinger equation. Louis de Broglie observed that either the standard deviation in the case of Gaussian, or the period ‘t’ in the case of Airy function, should be taken as ‘uncertainty parameters’ rather than geometrical quantities. According to Michael Berry and Nandor Balazs, the argument of Airy function actually represents a caustic, but in the phase space: it is the envelope of the ensemble of straight lines representing the corresponding uniform motions. The Berry-Klein theory of scaling the forces, in case it can be applied to a Wien-Lummer enclosure, acts as a universal gauging procedure which, in an undertaking of Georgescu-Roegen type, should be able to make us decide what is infrafinite, finite or transfinite.
