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. […]
Anno XLVI - n.4 - ottobre/dicembre 2013 Sul moto ellittico dei pianeti
A didactical approach to the elliptical motion of planets in the solar system is proposed. The planets’ velocities in apsidal points and the total mechanical energy of the two-body systems are discussed and described as functions of orbital parameters. Kepler’s third law is obtained from energy and angular momentum conservation principles. […]
