CHAPTER Structure and function In physical systems made by a large number of basic constituents one can observe collective properties which find their ...

No paradox exists in the fact that, in the Special Relativity, for the mass of a material body, considered in motion at constant speed, whose measure is u, the formula: m = m0/√ can be written, while for a photon the same formula holds, when between its source and the observer a state of relative motion at constant speed, whose measure is u, exists and it is observed along the direction perpendicular to the direction of his speed.

L'a. esamina il concetto di `amor vitae' come spiegazione della vita cosmica nel pensiero leonardiano e ritiene che questo costituisca la caratteristica inconfondibile della sua personalità. Nel secondo scritto l'a. si occupa del pensiero religioso di Leonardo «che ebbe soltanto fede nella religione serena e confortatrice della natura».

In this article the author reflects on some of the most recent instances of the hybridization of identities, brought about by movements of migration in the more general context of globalization. New situations triggered by the epoch-making historical developments of the world we live in require us to modify our notion of individual identity, which is no longer seen as a fundamental and self-referential essence of the individual, but rather as the product of a number of relational variables, many of (...) which arise from processes of ethnic amalgamation and cultural blending. In this new historical condition, one that old styles of thought are no longer able to grasp, the notion of memory is paramount. Memory, as Said has indicated, is connected to Vico’s concept of “invention” as “finding again,” that is, as an incessant process of the remembrance and the discovery of stories that are lived, leading to a “re-creation” and reconfiguration of one’s roots. This article, however, does not simply formulate, articulate and discuss the problem, but also raises the question of its genealogy, locating this in Vico’s distinction between the topical and the critical, that is connected with the triad of memory-imagination-ingenuity, and in certain philosophical positions – such as that of Dilthey, which is specifically acknowledged here – that involve an instance of hybridism, interpreted as a relationship between biological-natural and psychological subjectivity on one hand and historical-cultural identity on the other.
