Italia e Francia nell'Ungheria di Trianon (1919-1939): due modelli di penetrazione politico-culturale

Italy and France in Trianon’s Hungary: two political and cultural penetration models During the first post-war, the Danubian Europe was the theatre of an Italian-French diplomatic challenge to gain hegemony in that part of the continent. Because of his geographical position, Hungary had a decisive strategic importance for the ambitions of French and Italian foreign politics. Since in the 1920s culture and propaganda became the fourth dimension of international relations, Rome and Paris developed their diplomatic action in Hungary to affirm not only political and economic influence, but also cultural supremacy. In the 1930, after Hitler’s rise to power, the unstoppable comeback of German political influence in central-eastern Europe determined the progressive decline of Italian and French political and economic positions in Hungary: only the cultural field allowed a survey of Italian-Hungarian and French-Hungarian relations in the contest of a Europe dominated by Nazi Germany during the Second World War. Nevertheless, the radical geopolitical changes in second post-war Europe did not compromise Italian and French cultural presence in the new communist Hungary. Although cultural diplomacy is originally motivated by contingent political targets, it doesn’t respect the short time of politics, but it’s the only foreign politics tool that guarantees preservations of bilateral relations in the long run.

Reconstructing Quantum Field Theory from an Educational Perspective

The research work concerns the analysis of the foundations of Quantum Field Theory carried out from an educational perspective. The whole research has been driven by two questions: • How the concept of object changes when moving from classical to contemporary physics? • How are the concepts of field and interaction shaped and conceptualized within contemporary physics? What makes quantum field and interaction similar to and what makes them different from the classical ones? The whole work has been developed through several studies: 1. A study aimed to analyze the formal and conceptual structures characterizing the description of the continuous systems that remain invariant in the transition from classical to contemporary physics. 2. A study aimed to analyze the changes in the meanings of the concepts of field and interaction in the transition to quantum field theory. 3. A detailed study of the Klein-Gordon equation aimed at analyzing, in a case considered emblematic, some interpretative (conceptual and didactical) problems in the concept of field that the university textbooks do not address explicitly. 4. A study concerning the application of the “Discipline-Culture” Model elaborated by I. Galili to the analysis of the Klein-Gordon equation, in order to reconstruct the meanings of the equation from a cultural perspective. 5. A critical analysis, in the light of the results of the studies mentioned above, of the existing proposals for teaching basic concepts of Quantum Field Theory and particle physics at the secondary school level or in introductory physics university courses.
