Anno XLV - n.1 - gennaio/marzo 2012 Dispute scientifiche di ieri e di oggi
Reactions to the science of global warming have followed a similar course to those of other inconvenient truths from physics. […]
Anno XLVI - n.4 - ottobre/dicembre 2013 Diverse definizioni operative di “verticale”: un confronto
The concept of verticality is discussed with reference to its different meanings, e.g. the direction that points towards the zenith, the one which is parallel to the direction of free fall or is perpendicular to a level ground, etc. […]

If you were on the moon and tried to shoot a gun, would the bullet fire? And if so, in absence of air could an appropriate bullet reach a speed fast enough to orbit the Moon? Making use of considerations about mechanics, […]
Anno XXVIII - n.3 - luglio/settembre 1995 Elaborazione dei dati sperimentali: la cosiddetta “teoria degli errori”
We examine several “myths” of physics teaching that usually lead teachers in school to devote too much time to the treatment of inessential aspects to the detriment of more fundamental arguments. Among these we discuss the importance of numerical approximations, significant digits, […]
Anno XLIV - n.4 - ottobre/dicembre 2011 Energia dal vento. Esperienza didattica in un Istituto Professionale
Introducing the physics of wind turbines in a vocational school: from prior knowledge through experimental work to educational results. […]
Anno LI - n.2 - aprile/giugno 2018 Energia immagazzinata da un condensatore carico
The law that expresses the energy stored in a charged capacitor is obtained by an elementary algebraic calculation related to a simple discrete mechanical model. This model can be used in education, in a secondary school, as an alternative to continuous models that use integral calculus. […]
