Anno LI - n.2 - aprile/giugno 2018 La misura della costante di Planck: una proposta di attività laboratoriale
In the 2014/2015 school year, the Respighi Scientific High School started the “Fare Fisica: Planck 2.0” (Making Physics: Planck 2.0) project, aiming to challenge our best students thanks to the use of the laboratory. For this purpose we chose a modern physics experiment: the measurement of the Planck constant by means of the characteristic voltage – current of a LED. […]
Anno LI - n.2 - aprile/giugno 2018 Un esperimento “classico” rivisitato: la misura di h con i LED
A variation of the “classical” experiment for the measurement of Planck’s constant h using LEDs was proposed at the 2018 AI F Summer school of L’Aquila. This variation, in which the discharge of a capacitor provides the needed variable voltage and the measurements are made with an Arduino board, […]
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. […]
Anno LI - n.1 - gennaio/marzo 2018 L’origine dei crateri lunari: letture e proposte didattiche
This work reports the Italian translation of some parts of the English version of the paper that Alfred Wegener – best known for the continental drift theory – published in 1921 on “The origin of lunar craters”. One of the Moon craters is now named after Wegener. […]
Anno LI - n.1 - gennaio/marzo 2018 Proviamo a misurare la distanza Terra-Sole
Photographs of the last transits of Venus across the Sun, shot by amateur astronomers in 2004 and 2012, can be used to measure the mean distance between the Earth and the Sun (AU – Astronomical Unit). The method is simpler – although less precise – than the one proposed by the famous astronomer Edmond Halley about 300 years ago. […]
Anno LI - n.1 - gennaio/marzo 2018 Studio dell’effetto Est-Ovest con i rivelatori ArduSiPM
In this paper we present an experimental didactic approach to the study of cosmic rays with special focus on their interaction with the geomagnetic field of the Earth. The technique presented for the determination of the asymmetry of the flow coming from the east and the one from the west gives the possibility to introduce also concepts of statistics and processing useful data in experimental physics taught in high schools.
