Anno XXXIV - n.1 - gennaio/marzo 2001 Analisi del funzionamento di un orologio ad acqua
In this paper the author presents a discussion of the characteristics of a simple water clock built with a tin. Starting from experimental measurements, the emptying of the tin is theoretically described as a simple exercise. The theoretical result is tested on the experimental data and then used as model for the discussion. […]
Anno XXXVIII - n.3 - luglio/settembre 2005 Analisi del vento rilevato da una centralina meteo
The students of a vocational school installed a meteorological station and measured and studied the pattern of the winds. The activity proved to be a valid didactic experience with a scientific fallout because these were the first known data about the wind in the surroundings. […]
Anno XXVIII - n.1 - gennaio/marzo 1995 Analisi della velocità di propagazione di un impulso termico trasmesso per conduzione in un metallo
In this paper we are dealing with the phenomenon of propagation of a thermal pulse in solid metals. We are comparing results drawn from a mathematical model with data measured by connecting temperature probes to a computer on-line. […]
Anno XLIII - n.3 - luglio/settembre 2010 Analisi di un sistema di conversione dell’energia
In the context of the ‘Lauree Scientifiche – Scienza dei materiali’ project, highschool students analyze the energy transfers in a kit including a solar cell, two PEM cells (electrolyzer and fuel cell) and a fan, with special attention to the hydrogen stocking process in the reservoir. […]
Anno XLVI - n.2 - aprile/giugno 2013 Analizzare i fenomeni di caduta libera con il sensore di accelerazione dello smartphone
Mode of operation and examples of using smartphones as accelerometers in the physics lab […]
Anno XLVII - n.4 - ottobre/dicembre 2014 Anche i fisici hanno umane debolezze
Last Spring’s sensational news, then proved to be rash, about the discovery of gravitational waves originated after the Big Bang, illustrate some unfair aspects of the methods used by the scientists in divulgating the results of their researches […]
Anno XXIV - n.2 - aprile/giugno 1991 Ancora a proposito di un problema (elementare?) di termodinamica
In this note we present some remarks on the prediction of the equilibrium state in a horizontal, rigid, adiabatic cylinder divided into two chambers by an adiabatic piston. The two chambers contain two gases 1 and 2, at different pressures and temperatures. […]
