Anno XXIX - n.3 - luglio/settembre 1996 Entropia e informazione nell’opera di Léon Brillouin
After the second world war, the birth of cybernetics and information theory gave rise to new conceptual tools for exploring the meaning of entropy and understanding its relation with information. The key scientist who exploited in a systematic way the relation between entropy and information was Léon Brillouin. […]
Anno XLII - n.4 - ottobre/dicembre 2009 Equazione dei punti coniugati delle lenti: teoria, simulazione, esperimento
This paper describes how the refraction of light in optical lens can be modeled using the dynamic geometry software Geogebra. The models and the results obtained in the lab are compared. […]
Anno XXIII - n.2 (speciale: L'elaboratore nella didattica della fisica) - aprile/giugno 1990 Equilibrio termico: scheda di fisica e informatica
This paper describes a few simple school experiments on thermal equilibria that lend themselves to dynamical modelling. The construction and trying out of such models on a computer and the comparison of their results with the experimental data can give the opportunity for fruitful discussion in the classroom. […]
Anno XXVI - n.3 - luglio/settembre 1993 Equilibrio termico: un’esperienza introduttiva a un percorso didattico.
This paper describes an introductory experiment, leading to a definition of temperature based on the use mercury thermometer. The variation in time of the thermometer readings is the starting point for the construction of a mathematical model; this model will be later adapted to more complex systems approaching thermal – […]
