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” […]
Anno XXV - n.4 - ottobre/dicembre 1992 Sui quanti e la realtà. Giornata seconda
One of the most interesting conceptual “puzzles” of theoretical physics of this century (say the quantum theory of measurement) is presented, using the technique of a galileian dialogue. After a concise description of the foundations of the problem, the most important contributions to the subject are summarized in a simple form, […]
Anno XXXI - n.4 - ottobre/dicembre 1998 Sul concetto di tempo: breve percorso storico alla luce delle attuali conoscenze di astronomia e di cosmologia
We show how since the first human rational speculation the concept of infinite has dominated the time and how the peculiarities with which it has been considered have been modified in the same time that the astronomical researches have become deeper. […]
Anno XXXI - n.1 - gennaio/marzo 1998 Sul galleggiamento dei corpi
The buoyancy conditions of solid homogeneous bodies floating in an ideal liquid are studied with special attention towards stable equilibrium. The case of a solid floating cylinder is discussed in detail. […]
