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 XXVII - n.4 - ottobre/dicembre 1994 Cos’e’ un lock-in? a che cosa serve? come costruirne uno?
A short description of the lock-in technique gives an idea of the working principle of these useful devices, that are widely used in weak signal detection, but rarely treated in introductory courses. Simple and cheap circuits, that may be easily assembled by the student are suggested, […]
Anno XXVII - n.3 - luglio/settembre 1994 Einstein contro la meccanica quantistica
This article deals with the most important characteristic of Einstein thought, in relation to his opposition versus the Quantum Mechanics. A new explanation is proposed for this contrast: Einstein tries to understand microscopic phenomena by a non linear theory, to obtain with an opportune generalization the General Relativity. […]
Anno XXVII - n.3 - luglio/settembre 1994 L’insegnamento della meccanica al biennio della scuola media superiore. Prima parte: la proposta
We propose an unconventional teaching approach to newtonian mechanics at high school level (age 14-15). Force and energy concepts are simultaneously introduced from the very beginning and then developed through the teaching sequence, with increasing levels of differentiation and formalization. First we sketch basic lines of our proposal and then we suggest some experimental works to perform in classroom setting. […]
Anno XXVII - n.3 - luglio/settembre 1994 L’insegnamento della meccanica al biennio della scuola media superiore. Parte seconda: la sperimentazione
A research has been performed in classroom settings, in order to test the didactic effectiveness of original teaching approach to Newtonian mechanics proposed in a previous paper. Two high school classes (students 14-15 years old) were involved in the teaching experiment. […]
