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. […]
Anno XXVIII - n.1 - gennaio/marzo 1995 L’analogia idrodinamica e lo sviluppo della teoria elettromagnetica di Maxwell
In 1855 Maxwell developed a formal analogy between the motion of an incompressible fluid, the electric current in a conductor, and the lines of force of a magnetic field. His analysis represents an example of interdisciplinary study of physical phenomena in the past, […]
