Anno XXV - n.4 - ottobre/dicembre 1992 Un semplice esperimento di carattere frattale
By making paper balls with crumpled sheets of paper and studying the functional relationship between their mean diameters versus their mass it is possible to introduce the concept of fractional dimensions to students. […]
Anno XLIV - n.4 - ottobre/dicembre 2011 Un semplice spettroscopio
Measuring light spectra with a simple homemade grating spectroscope. […]
Anno XXIX - n.3 - luglio/settembre 1996 Un sistema a fotocellule per esperienze di meccanica
This note describes a system based on photogates and interfaced to a PC that can be particularly useful in physics experiments in which the description of objects’ motion is relevant. The PC role is twofold: on one side it is the system timer, […]
Anno XXXI - n.3 - luglio/settembre 1998 Una bambola che cambia colore
A simple to make but not so simple to explain experiment on polarized light is described and explained. […]
Anno XLVI - n.2 - aprile/giugno 2013 Una caccia al tesoro scientifica: dove sta l’accelerometro in uno smartphone?
Current smartphones are equipped with many sensors and that offer a wide choice of applications like measuring accelerations, sounds, distances, angles, etc. Smartphones are becoming increasingly widespread among students who could use them as “personal instruments” for physics measurements. The article describes a kind of scientific treasure hunt: finding the location of the smartphone’s accelerometers by applying the laws of physics of uniform circular motion […]
