Anno XXIV - n.1 - gennaio/marzo 1991 Trasporto di inquinanti dal mare all’atmosfera
The bubble-breaking, droplet-ejecting mechanism is the main pathway of the mass-transport effect at water to air interface (primarily at sea-air interface, but also lake, river…). Surface-active organic material (SAOM) tends to concentrate at the water surface. The bubbles, produced primarily by breaking waves, […]
Anno XXIV - n.1 - gennaio/marzo 1991 Superconduttività ad alta temperatura
A short phenomenological description of the behaviour of the classic low-temperature superconductors is given. A brief history of the progresses achieved during the past half century in the search of “high temperature superconductors” introduces to the recent discovery of the new ceramic superconductors. […]
Anno XXIV - n.1 - gennaio/marzo 1991 Dimostrazioni con superconduttori ad alta temperatura. (traduzione a cura di Santino Bruzzone)
Some experiments with home-made HT superconductors are reported. […]
Anno XXIV - n.1 - gennaio/marzo 1991 Uso della simulazione per lo studio del moto in sistemi di riferimento diversi
It is well known that high school students meet difficulties in visualizing the motion of an object in different frame of reference and in understanding how observations made by different observers are related. This paper presents a package, based on computer simulations, […]
Anno XXIV - n.1 - gennaio/marzo 1991 Il moto dei corpi in un fluido viscoso: un’esperienza per valutare la resistenza del mezzo
This work describes an experiment, carried out with rather simple devices, on the quantitative study of the motion of some spheres, made of different materials, freely falling in water. We also propose a simulation program, written in Pascal language, allowing to compare the results of a theoretical model with the experimental data. […]
Anno XXIV - n.1 - gennaio/marzo 1991 Prove scritte di Fisica per la Maturità Scientifica Sperimentale: testo e proposte di soluzione (terza parte)
This article completes a survey of the physics problems assigned since 1979 in the written tests of the final examinations in experimental secondary schools. We offer the solution of each problem and, occasionally, a short comment. NOTA – Il titolo stampato sulla rivista riporta, […]
Anno XXIV - n.1 - gennaio/marzo 1991 Un corso di aggiornamento sull’Educazione scientifica nella scuola elementare
In this report we describe an example of inservice training course for primary school teachers. The course was carried out in a university physics laboratory. The teachers were engaged with “raw” problems. It is interesting to note that facing a new situation the behaviour of teachers is not very different from the behaviour of pupils. […]
Anno XXIV - n.1 - gennaio/marzo 1991 Premio Bonacini 1988: Fenomeni elettrici e fenomeni magnetici. 1° Premio: scuola media statale “G. Salvemini”, Varese
This article describes the first prize-winning entry to the l988 “Premio Bonacini” contest for middle-school children on electrical and magnetic phenomena. The 13 year-old pupils designed and built the apparatus and performed the experiments. The project required good organisation, division of responsibilities, […]
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 XXIII - n.4 - ottobre/dicembre 1990 Conoscenza della Fisica all’ingresso e all’uscita dei corsi universitari di base
The article reports the results of an investigation on the knowledge of physics related to common sense patterns of knowledge of Italian students in the first year of University. The results were communicated both to the students and to the teachers of the courses. […]
