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. […]
Anno XXXVI - n.2 - aprile/giugno 2003 Ancora sulle derivate del seno e del coseno (calcolate in maniera elementare)
The article shows how the derivatives of the trigonometric functions sine and cosine can be calculated with simple but rigorous geometrical reasoning. […]
Anno XXXV - n.4 - ottobre/dicembre 2002 Anemometro per CBL
Modern portable data acquisition systems (RTL) allow easy performing didactical experiments on environmental sciences and metereology. This simple anemometer, added to exhisting thermometer, barometer, and hygrometer, offers the possibility of using a simple and cheap portable meteo-station. […]
