Einstein, Planck and Vera Rubin: Relevant Encounters Between the Cosmological and the Quantum Worlds
2021
In Cosmology and in Fundamental Physics there is a crucial question like: where the elusive substance that we call Dark Matter is hidden in the Universe and what is it made of? that, even after 40 years from the Vera Rubin seminal discovery [1] does not have a proper answer. Actually, the more we have investigated, the more this issue has become strongly entangled with aspects that go beyond the established Quantum Physics, the Standard Model of Elementary particles and the General Relativity and related to processes like the Inflation, the accelerated expansion of the Universe and High Energy Phenomena around compact objects. Even Quantum Gravity and very exotic Dark Matter particle candid…
"Paolo Boccone’s curious observations and the Commitment to Visual Communication of Natural History", speech at International Conference "Art and Sci…
2015
In his "Recherches et observations naturelles" (Amsterdam 1674) the botanist Paolo Boccone (1633- 1704) presents himself as an advocate of a new visual method. He was supported by Jan Swammerdam, with whom he shared his scientific observations. Boccone claims to be the first to apply microscopic dissection to figured stones, in order to distinguish accidental shapes from natural ones. Boccone, as many of the members of the scientific community with whom he corresponded, had a strong commitment to painstaking observation and visual communication, that he was able to handle on many levels. The allegorical frontispiece of "Recherches" is aimed to present a range of moral and psychological atti…

Co-evolution of three mega-trends nurtures un-captured GDP : Uber's ride-sharing revolution
2016
Uber used a disruptive business model driven by digital technology to trigger a ride-sharing revolution. The institution- al sources of the company’s platform ecosystem architecture were analyzed to explain this revolutionary change. Both an empirical analysis of a co-existing development trajectory with taxis and institutional enablers that helped to create Uber’s platform ecosystem were analyzed. The analysis identified a correspondence with the “two-faced” nature of ICT that nurtures uncaptured GDP. This two-faced nature of ICT can be attributed to a virtuous cycle of decline in prices and an increase in the number of trips. We show that this cycle can be attributed to a self-propagating…
Analysis of dust exposure during chainsaw forest operations
2017
Abstract: In 1999, the European Union proclaimed hardwood dust carcinogenic based on the classification of the International Agency for Research on Cancer (IARC) issued in 1995. The operational exposure limit (OEL) for inhalable wood dust has been set to 5 mg m-3 by EU directives, though in different countries the OEL ranges from 1 to 5 mg m-3. The objective of this study was to determine the exposure to wood dust of forest workers in chainsaw cutting and processing and suggest possible countermeasures. The study took into consideration different silvicultural treatments (coppice clear cut, conifer thinning, conifer pruning, and sanitary cut) and chainsaw fuel (normal two-stroke gasoline mi…

Post-fotografia etnografica
2021
È evidente come la nostra società tecnologica sia legata senza alcun dubbio alla diffusione delle immagini. Autori come Gottfried Boehm, John Mitchell, Hans Belting hanno indagato la natura dell'immagine ponendo le basi, negli anni Novanta, per l'idea di un pictorial turn, di una cultura totalmente dominata dalle immagini che è diventata adesso una possibilità tecnica reale su scala globale. Un nuovo statuto dell'immagine che si usa raccogliere sotto l'etichetta di iconic turner inserito nel più vasto campo visual culture studies. L'uso del termine cultura accanto a quello di visuale è indicativo dell'ampiezza del campo d'indagine che visual culture studies si prefiggono di ricercare: essi …
Ingenium e natura umana in Giambattista Vico.
2009
Abstract. In the present theories about human nature there are some attempts to naturalize the mind; on the other hand there are tendencies of thought that criticise those ideas. Vico’s work can be considered the foundation of theories which refuse to naturalize humans. Vico had an anti-dualistic view of human nature, centred on ingenium and related to the ideas of action, language, civil world and culture. This essay analyses Vico’s concept of ingenium and proposes a reflection about his epistemology (1), philosophy of mind (2) and philosophy of language (3). (1) Knowledge and truth are connected to human praxis and action. Vico’s theory of knowledge is based on the verum-factum principle.…
