A thermodynamical model of how the formation, uplift and height of clouds depends on ground temperature and relative humidity is described. […]
This article explains how to acquire digital data from the parallel port of an IBM-compatible PC. Several experiments in the field of Mechanics, involving time measurements, may be done this way by simply connecting suitable switches (mechanical or optical) to the control lines of the port. […]
A smartphone, with its integrated sensors and CPU, can aid experiments in many different areas of physics. We show how the resonant frequencies of a pipe can be measured using a smartphone and a Bic pen […]
The paper presents three simple acoustic experiments carried out using a smartphone and some objects available in any kitchen. […]
