Anno XXIV - n.3 - luglio/settembre 1991 Le trasformazioni energetiche (Scuola media statale “S. Taricco”, Cherasco CN)
This article describes an entry to the Bonacini Annual Contest lor experimental work in the school. The theme of the Contest was “Energy Transformations”. In their practical work, the 12-year old pupils built simple appliances in which different kinds of energy transfers took piace. […]
Anno XXVII - n.4 - ottobre/dicembre 1994 Legge e caso alle origini della fisica contemporanea
The European culture at the turn of the century developed a deep criticism of the concept of “natural laws”. In the meantime, the new concept of “statistical law” was found to be useful and fruitful. The paper proposes a review of the positions on this issue of the physicists and philosophers like Boltzmann, […]
Anno XLI - n.4 - ottobre/dicembre 2008 Leggi, dimensioni e segno di uguaglianza

These require introducing auxiliary quantities and coefficients whose physical definitions and numerical values depend on the unit system chosen. […]
Anno LVI - n.2 - aprile/giugno 2023 Lente cilindrica e misura dell’indice di rifrazione dell’acqua
Geometric optics, even in the simple paraxial approximation, has significant explanatory capabilities across various phenomena. As an example of its predictive power, we present a measurement of the water refraction index by studying the focal properties of a cylindrical lens realized with readily available materials. […]
Anno XXVII - n.1 - gennaio/marzo 1994 Lenti e specchi. (Premio Bonacini: Scuola media statale di Cherasco CN, 2° Premio)
The work describes a series of simple experiments done by thirteen year old students It included the construction of a kaleidoscope and other experiments on geometrical optics. […]
