Anno XXXIII - n.1 - gennaio/marzo 2000 Un semplice contatore Geiger tascabile per α, β e γ
A simple pocket-size, battery operated Geiger counter is here described. It may be used in classroom to test low emission radioactive sources, or to detect background radiation. […]
Anno XLVI - n.4 - ottobre/dicembre 2013 Un semplice dispositivo con cui esplorare le onde radio generate da un telefonino
A simple low cost homemade device that converts radio wave energy from a mobile phone signal to electricity for lighting an LED is described. No battery or complex circuitry is required. The device allows a range of interesting experiments on the physics and technology of mobile phones. […]
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. […]
