**7. Conclusions**

In these concluding notes, we would like to try to put this contribution in context. In our opinion, the non-viewability of quantum processes has generated the widespread belief that they are inherently incomprehensible. Quantum theories are often assimilated into formal recipes that are very effective on the predictive level but are ones whose connection with any intelligible ontology remains obscure. Following the historical precedent of non-Euclidean geometries, we tried to circumvent these obscurities by providing a model of quantum behavior in a classical context: that of electrical circuits. As in the case of non-Euclidean geometries, we had to redefine the notions of particle, wave, and corpuscle in this context, moving away from their original classical meaning. By paying this price, we obtained the visualization of quantum entities and processes, guaranteed by the classical nature of the context in which their redefinition was carried out.

We believe that this attempt is located in a sort of middle land between the choice of surrendering to non-visualization (with the consequent problems of conceptual opacity) and the strong choice of determining an ontology of elementary processes, which is the goal of any physical interpretation of the quantum formalism. Although in choosing our representative model, we tried to adhere to the criteria of "sound physics", we find it difficult to seriously believe that space is the equivalent of a cabinet of electric capacitors. Our representation is, therefore, less than a sensu strictu interpretation of quantum formalism such as, for example, Bohm's [22] and relative state [23] interpretations. At the same time, however, it is more than just a surrender to mystery and allows for an analogical narrative of concepts such as the wave function or the particle–wave dualism. Our aim is to facilitate the communication related to quantum processes, through images that can be understood by anyone familiar with the basics of classical physics concerning electrical circuits.

This objective responds to a pedagogical need that has been our strongest motivation and seems particularly urgen<sup>t</sup> to us in a moment like the present one, in which quantum theories have become part of the educational background of the new generations of engineers and technologists, engaged in the development of the amazing technologies that the quantum nature of reality makes possible.
