A ‘physically consistent’ way of explaining tides to secondary school pupils is suggested and described. […]
An experimental exercise on using a pendulum for measuring masses, proposed to the Italian students enrolled in one of the national sessions of the Physics Olympiads, is described and discussed. […]
A computer-aided data acquisition and analysis tool is proposed for studying the behaviour of a pendulum coupled to a low-friction rotary sensor. […]
A thermodynamical model of how the formation, uplift and height of clouds depends on ground temperature and relative humidity is described. […]
In the 17th century De Dominis, Galilei and Newton proposed three different theories on the tides. Eventually Newton’s theory, some aspects of which recall the other two, was adopted. This paper proposes a school activity in which the three theories are compared. […]
When interpreting experimental results, context is everything. The researchers who took and analyzed the most important eclipse data had good reasons for judging the experiment a victory for Albert Einstein. […]
The debate on the correctness of the 1919 eclipse experiment is still in progress. This paper aims to contribute by analyzing the available data on the instruments, the achievable accuracy versus what would have been necessary and some experimental details not currently available in the relevant literature. […]
Using iron filings and the well known GEOMAG magnetic toy we build and demonstrate unusual and interesting magnetic fields. […]
This paper describes how the refraction of light in optical lens can be modeled using the dynamic geometry software Geogebra. The models and the results obtained in the lab are compared. […]
