Anno XLII - n.1 - gennaio/marzo 2009 Correndo sotto la pioggia
The well known question: ‘is it better to walk or to run in the rain’? can be advantageously proposed to secondary school students. The paper illustrates a method for estimating the number of raindrops vs speed that fall on a moving surface. […]
Anno XXXIX - n.1 - gennaio/marzo 2006 Correzioni alla legge di Stokes per la misura della viscosità di un liquido
The viscosity of a viscous medium can be found by measuring the terminal velocity of small falling spheres and applying Stokes’ law. The experiment is didactically interesting and easily performed in school, but because of the finiteness of the medium edge effects produce theoretical and experimental difficulties. […]
Anno XXVII - n.4 - ottobre/dicembre 1994 Cos’e’ un lock-in? a che cosa serve? come costruirne uno?
A short description of the lock-in technique gives an idea of the working principle of these useful devices, that are widely used in weak signal detection, but rarely treated in introductory courses. Simple and cheap circuits, that may be easily assembled by the student are suggested, […]
Anno XLVI - n.1 - gennaio/marzo 2013 Cosa ci resta da scoprire?
Antonio Ereditato, former chairman of the OPERA collaboration at CERN and Gran Sasso, shares with the reader his views on the challenges that physics will be facing in the near future. He suggests five great questions that touch the limits of our present knowledge and represent a daring dream for scientists. […]
Anno XXVII - n.2 - aprile/giugno 1994 “Cose” e “Situazioni”. Modelli alternativi per la descrizione della fisica dei Sistemi Materiali.
Some considerations concerning the Physics of matter are made. In particular we stress that the knowledge of some general aspects of modern physics (like atomic and molecular physics, do not help in the teaching of the elementary physics, especially as far as every-day phenomena are concerned. […]
