Anno XL - n.4 - ottobre/dicembre 2007 Galleggianti che si attraggono
We can commonly notice small things – leaves, pieces of paper, etc., – adhering to each other and floating together on the water. The reasons of this behaviour are explained. […]
Anno XXIV - n.2 - aprile/giugno 1991 Gas perfetti e gas reali. 1° Premio: Liceo Scientifico Statale “A. Tassorlin, Modena
We begin to study the properties of gases through a well-known mechanical model, then we perform a school-Iab replica of Volta’s experiment on the dilatation of gases at constant pressure. After observing that the behaviour of air is close to that of ideal gases, […]
Anno XXIV - n.2 - aprile/giugno 1991 Gas perfetti e gas reali. 2° Premio: Liceo Classico “Virgilio”, Empoli FI
A few experiments on the behaviour of real gases were performed. They show that the behaviour of air at constant temperature is quite similar to that of an ideai gas but, at constant pressure and varying temperature, the different behaviours of various gases (air, […]
Anno XXVI - n.1 - gennaio/marzo 1993 Geometria dello spazio-tempo e paradossi relativistici
The classical skier paradox is revisited, with the aim of showing that a strictly geometric approach (i.e. one that makes no use of Lorentz transformations and the like) is more apt at revealing the true nature of the physical problem being studied. […]
