Anno LIV – n.3 – luglio/settembre 2021 Come interpretare l’esperimento del disco di Newton?
In 1666 Newton decomposed white light with a prism to make so-called appear rainbow colors. He represented these colors on a disk, which we usually spin to make white appear. But it’s this experience that’s really symmetrical to that of the prism? […]
Anno XXXIII - n.1 - gennaio/marzo 2000 Come mettere in luce i vincoli fisici per la vita usando i numeri puri
A crude device for quantification shows how diverse aspects of distantly related organisms reflect the interplay of the same underlying physical factors […]
Anno XXVI - n.1 - gennaio/marzo 1993 Come misurare l’altezza di un satellite… guardando la televisione
This article deals with a rather simple method for measuring the height of telecommunication geostationary satellites. By observing the same telecast on two side by side displays, one of which is receiving the satellite image while the other is receiving from ground relay, […]
Anno XXXI - n.2 - aprile/giugno 1998 Come valorizzare un antico esperimento didattico con la tecnica MBL: la macchina di Atwood per condurre una ricerca sperimentale sul moto
Atwood’s machine is a device born in the XVIII century as an aid for teaching mechanics; a reduced and simplified version of such device still appears in physics textbooks, as an application of Newton’s second law. An Atwood’s machine interfaced to a PC by means of position and force sensors becomes a device for a detailed investigation on the motion of bodies subject to forces that change with position. […]
