Anno XXXIV - n.4 - ottobre/dicembre 2001 Isolanti e conduttori nelle esperienze di elettrostatica
The difficulty that is attributed to electrostatic experiments and the little favour that these hold among many teachers generally lies in not knowing the electric properties of the materials in the conditions in which the experiments are intended to be carried out: high tension and a very small electrical charge. […]
Anno XXXIII - n.3 - luglio/settembre 2000 Jordan, Pauli, politica, Brecht e una costante gravitazionale variabile
Pascual Jordan was one of the great theoretical physicists of the century. But his attempt to modify general relativity with a variable gravitational constant did nothing to enhance his reputation. Nor did his conspicuous membership in the Nazi Party. […]
Anno XLVI - n.3 - luglio/settembre 2013 Joseph Louis Lagrange a duecento anni dalla morte
The Piedmontese mathematician Joseph Louis Lagrange died in Paris 200 years ago. His interesting life and his scientific achievements are recalled and described […]
Anno XXXII - n.1 - gennaio/marzo 1999 Joule e l’equivalente meccanico del calore: tra storia della fisica e didattica
After the introduction of Joule’s work, his paddle wheel experiment is analysed. The conceptual simplicity of this experimental apparatus makes itself a useful didactic model. Therefore its reproduction, the execution of the experiment and the possible didactic purposes will be described. […]
Anno XXXIV - n.4 - ottobre/dicembre 2001 L’affare girasole o “all’inseguimento del Sole”
The students of the last class of a French scientific lyceum built an electronic device that can follow the sun like a sunflower. The circuit can be used to orient solar panels in an energy-saving project. This school project has a multidisciplinary nature: for example it can be associated with the study of nervous signals in biology and can introduce the topic of artificial intelligence. […]
