Anno XXXII - n.1 - gennaio/marzo 1999 Una lampada al sodio di basso costo
Low pressure discharge lamps, filled with mercury or sodium, are commonly used for highways and tunnels illumination, especially against fog. A simple, low cost, monochromatic light source may be obtained by means a sodium lamp of this type. […]
Anno XXXVI - n.3 - luglio/settembre 2003 Una macchina elettrostatica… statica!
An E.H.T. generator which may be used in all experiments and demonstrations instead of the old fashioned electrostatic machines is described. It has none of the drawbacks of the old machines and its design gives special attention to the safety of the operator. […]
Anno XXXVII - n.4 - ottobre/dicembre 2004 Una misura del calore prodotto per attrito
This paper describes a simple method for measuring the heat developed by friction, in which a thermometer in used as a calorimetric device. […]
Anno LVI - n.2 - aprile/giugno 2023 Una misura del raggio terrestre per turisti
In the Tuscan Archipelago it’s possible to make an approximate measurement of the Earth’s radius from the Elba Island using the Pianosa Island as a ship that appears and disappears on the horizon depending on the observer’s height above sea level. […]
Anno XXV - n.2 - aprile/giugno 1992 Una misura della densità dell’aria
We describe, in this paper, a measurement of the density of air, using the equation of state for gases and Archimede’s law. […]
