Anno XXX - n.3 - luglio/settembre 1997 Un oscillatore non lineare
Non-linear physics is a fairly complex matter to handle. A physical system presenting a bifurcation, a non-linear oscillator, is described here along with the mechanical simulation of its potential, with the aim to offer a method of introduction of non-linear systems in secondary schools. […]
Anno XXXVII - n.3 - luglio/settembre 2004 Un’osservazione Galileiana. La misura del periodo di rivoluzione dei Pianeti Medicei
Galileo’s measurement of the period of revolution of Jupiter’s satellites was repeated in 18 days of observation, accurate measurements of the position of the satellites, their identification and the interpolation of their positions. The radii of the orbits of the four satellites and the mass of Jupiter were calculated. […]
Anno XXV - n.2 - aprile/giugno 1992 Un particolare pendolo fisico per ricavare la relazione fra il periodo e la gravità
A pendulum whose piane of oscillation can be inclined at will between vertical and horizontal was designed, built and used to measure the effect of varying g on its period of oscillation. […]
Anno XLIII - n.4 - ottobre/dicembre 2010 Un pendolo smorzato, con piano di oscillazione variabile, studiato con RTL
A computer-aided data acquisition and analysis tool is proposed for studying the behaviour of a pendulum coupled to a low-friction rotary sensor. […]
Anno XLVIII - n.2 - aprile/giugno 2015 Un possibile metodo di misura della coppia sviluppata da un motore elettrico
An electronic way to measure the mechanical torque developed by an electric motor is noted. The measurement is made solely on the stator. […]
Anno XXIX - n.2 - aprile/giugno 1996 Un problema “reale” per capire la fisica
Tacking a Real World Problem for Understanding Physics. Scientific knowledge is a complex game aimed at constructing a representation of reality characterised by specific questions, languages, ways of operating. Acquiring scientific knowledge therefore involves the ability of thinking and operating within a representation of reality, […]
Anno XXXVI - n.3 - luglio/settembre 2003 Un progetto di introduzione della meccanica quantistica per i laureati in matematica
The article presents the general lines of a project on quantum mechanics developed for a 32-hour course in the context of pre-service training of Secondary School Teachers in mathematics & physics. The students had a degree in Mathematics and had never met quantum mechanics before. […]
