Anno XXIII - n.3 - luglio/settembre 1990 L’astronomia: un’applicazione della fisica
Newtonian gravitational laws explain the motions of planets around the Sun and the motions of double stars around their center of mass. Small deviations from the predictions of these laws have given confirmation of the general relativity theory. Astrophysics, by means of the analysis of the electromagnetic radiation emitted by the celestial bodies permits us to derive the surface temperature of stars, […]
Anno XXX - n.3 - luglio/settembre 1997 L’attimo fuggente: ovvero come verificare la rotazione della Terra in meno di venti minuti
The rotation of the Earth produces an effect on the behaviour of a sufficiently long pendulum, as in Foucault’s experiment in 1851. This article illustrates an easy method to measure the Earth’s angular velocity with acceptable accuracy and in less than 20 minutes. […]
Anno XLIII - n.1 - gennaio/marzo 2010 L’eclisse del 1919 e la teoria della relatività – il ruolo dei pregiudizi
When interpreting experimental results, context is everything. The researchers who took and analyzed the most important eclipse data had good reasons for judging the experiment a victory for Albert Einstein. […]
Anno XLIII - n.1 - gennaio/marzo 2010 L’eclisse del 1919: un esperimento di grande delicatezza. L’accuratezza degli strumenti e le tecniche impiegate furono adeguati?
The debate on the correctness of the 1919 eclipse experiment is still in progress. This paper aims to contribute by analyzing the available data on the instruments, the achievable accuracy versus what would have been necessary and some experimental details not currently available in the relevant literature. […]
Anno XXXII - n.3 - luglio/settembre 1999 L’educazione alla conoscenza scientifica: un percorso che parte da lontano
This paper aims at clarifying what education in science may mean in the real context of classroom activities. In particular the meaning of education in physics will be illustrated by looking at the development of concepts and methods within a perspective of continuity in the teaching of science at the level of compulsory education, […]
