Anno LI - n.1 - gennaio/marzo 2018 Studio dell’effetto Est-Ovest con i rivelatori ArduSiPM
In this paper we present an experimental didactic approach to the study of cosmic rays with special focus on their interaction with the geomagnetic field of the Earth. The technique presented for the determination of the asymmetry of the flow coming from the east and the one from the west gives the possibility to introduce also concepts of statistics and processing useful data in experimental physics taught in high schools. […]
Anno XXXIV - n.3 - luglio/settembre 2001 Studio di problemi non lineari
A one-dimensional dynamical system of 64 particles with forces between neighbors containing nonlinear terms has been studied on the Los Alamos computer Maniac I. The nonlinear terms considered are quadratic, cubic and broken linear types. The results are analysed into Fourier components and plotted as a function of time. […]
Anno XXXIV - n.2 - aprile/giugno 2001 Studio sperimentale della caduta di una sfera in aria, con le possibilità offerte dalle nuove tecnologie
In this article we describe on-line experiments involving spheres falling in air, using graphic calculators connected to CBL units and distance sensors, which permit a quick acquisition and analysis of the experimental data. Comparing the motion graphs of a billiard ball and a light polystyrene sphere, […]
Anno XXXVIII - n.3 - luglio/settembre 2005 Studio sperimentale di una cella fotovoltaica
An experimental investigation on the electro-optical behavior of a photodiode was carried out using an RTL acquisition system with current and voltage probes. Information is given on the theoretical background and the results of measurements aimed at identifying the conditions of maximum photovoltaic efficiency are reported. […]
Anno XXIII - n.3 - luglio/settembre 1990 Su un metodo di analisi dei dati di un calorimetro on-line
The results of a low cost on-line experiment on calorimetry are analysed in order to deduce both the thermal capacities of the liquid samples under study and the heat losses of the apparatus. […]
Anno XXIII - n.4 - ottobre/dicembre 1990 Sui quanti e la realtà
This “galilean dialogue” briefly considered the debate regarding the conceptual foundations of quantum mechanics, expecially referred to the Einstein/Bohr discussions about the interpretation of quantum formalism. In this presentation, Simplicio represents Einstein’s position, while Salviati defends Bohr. In the article, the problems arising from the so called “quantum non separability” […]
