Anno XXIV - n.2 - aprile/giugno 1991 Problems related to numerical resolution in on-line data acquisition are discussed and different smoothing techniques for data analysis are proposed. […]
Anno XXXII - n.3 - luglio/settembre 1999 In the study of subjects at the borderline between Thermodynamics and Mechanics, typical aspects of one of the two sciences are sometimes overlooked and incomplete, contradictory or partially erroneous descriptions are given. We find this type of difficulty in situations where there are objects in motion and, […]
Anno XLI - n.1 - gennaio/marzo 2008 Looking through a pitcher full of water reveals a surprising optical effect. […]
Anno LIV – n.2 – aprile/giugno 2021 Among the first electrostatic machines, the one developed by Edward Nairne, a skilled English instrument maker of the second half of the eighteenth century, should be mentioned. This electrostatic generator is little known, however it was used in medical field for over a century. […]
Anno XLV - n.1 - gennaio/marzo 2012 Reasoning on what happens when connecting two charged capacitors suggests a general procedure for evaluating the energy associated with the propagation of electromagnetic waves. […]
Anno XXVIII - n.2 - aprile/giugno 1995 We test experimentally the free electron gas model for electric conduction in metals by means of measurements of the Hall coefficient. Full details for the construction of the experimental apparatus are given. […]
Anno XXXI - n.4 - ottobre/dicembre 1998 Using a very easy experiment, conductivity quantization can be observed. In this way quantum mechanics becomes something students can also experiment. […]
