Anno XXIX - n.4 - ottobre/dicembre 1996 Magia con la luce
This note describes an alternative classroom demonstration of Newton’s classic method to mix, by means of a prism, rainbow colours to get white light again. […]
Anno XLIII - n.2 - aprile/giugno 2010 Magnetismo, effetto relativistico
Following a high-school teaching method we propose the subject-matters used in 1905 by A. Einstein to explain the relativistic effect of a magnetic field. Following the Lorentz-Einstein transforms in time and space, we show that what appears as an electric field in an inertial reference system can be seen in another relativistically equivalent system as a magnetic field. […]
Anno XXXI - n.2 - aprile/giugno 1998 Mappe concettuali come strumenti per accertare l’apprendimento in fisica
Quantitative measures of concept maps drawn by senior high-school students are shown to be useful in assessing the understanding of relationships between the concepts required for multistep problem solving. […]
Anno XLIII - n.1 - gennaio/marzo 2010 Maree: che cosa Newton deve a De Dominis e Galileo
In the 17th century De Dominis, Galilei and Newton proposed three different theories on the tides. Eventually Newton’s theory, some aspects of which recall the other two, was adopted. This paper proposes a school activity in which the three theories are compared. […]
Anno XXIX - n.4 - ottobre/dicembre 1996 Massa inerziale e gravitazionale: aspetti storici e didattici
In the study of Mechanics, both at secondary school and university levels, the conceptual distinction between inertial and gravitational mass is often hurriedly discussed with the aim of unifying the two quantities as soon as possible. Fundamental contributions to the clarification of the distinction between the two quantities and to increasing the accuracy of the experiments to check their proportionality were given by great physicists as Newton and Einstein, […]
Anno XXIII - n.1 - gennaio/marzo 1990 Meccanica quantistica ed evoluzione nei rapporti tra Fisica e Matematica all’inizio del XX secolo
The paper deals with a sort of discrepancy between the historical development of Quantum Mechanics and the way it is generally taught. Quantum Mechanics is usually presented after its fundamental postulates, while this is not easy to connect to the real historical evolution of the basic ideas. […]
Anno XXXVI - n.4 - ottobre/dicembre 2003 Medicina nucleare
This article describes the use of nuclear medicine techniques in diagnosis and therapy. The process of generating radiopharmaceuticals is introduced and relevant interactions of radiation with matter are discussed. Instrumentation in diagnostic nuclear medicine is described and future trends in nuclear medicine imaging technology are predicted. […]
