L’articolo esplora il tema dei viaggi nel tempo nella filmografia di Christopher Nolan, focalizzandosi su Interstellar (2014) e Tenet (2020). In Interstellar, la narrazione fonde il rigore scientifico, grazie alla consulenza del fisico Kip Thorne, con elementi fantascientifici per affrontare questioni esistenziali e ambientali. L’umanità è costrett...

Energy Return on Investment (EROI, sometimes EROEI) is one of the most important indices for evaluating the efficacy of a primary energy source. It is generally defined as the relation between the energy extracted from a given resource and the energy costs diverted from society to extract it. In this paper, the EROI of 30 oil companies was calculat...

The behavior of complex systems is one of the most intriguing phenomena investigated by recent science; natural and artificial systems offer a wide opportunity for this kind of analysis. The energy conversion is both a process based on important physical laws and one of the most important economic sectors; the interaction between these two aspects...

The aim of this paper is to show how the studies in Energy field are intrinsically cross-disciplinary. Energy undergoes to the general Physics laws and, in particular, to the Thermodynamics ones, but often we think it like a separate field, regard, for example, to the Ecology. We show some example useful to see the analogy between those fields of s...

The EROI is one of the most important indices to evaluate the net energy output of a source of primary energy (there is a lively debate on the usability of this kind of parameter, but here we will use it under the hypothesis that it is a good way to establish if an oil company has a level of efficiency close to other energetic sources). It is gener...

A phase plot of the oil economy is built using the literature data of world oil production, price, and EROEI (Energy Returned on Energy Invested). An analogy between the oil economy and the Benard convection is proposed; some methods of interpretation and forecast of the system behavior are also shown based on "phase portrait" using as main variabl...

Ventilatori che assordano, il reostato esclude numeri di resistenze ohmiche che, come preghiera, si narrano sempre nella medesima sequenza. La velocità aumenta. Gli assorbimenti sui motori raggiungono le tacche rosse: 3.000 volt (nominali) per 400 ampere fanno 1.200.000 watt. I motori delle ferrovie italiane sono per la maggior parte tutti in corre...
