The students of a vocational school installed a meteorological station and measured and studied the pattern of the winds. The activity proved to be a valid didactic experience with a scientific fallout because these were the first known data about the wind in the surroundings. […]
In this paper we are dealing with the phenomenon of propagation of a thermal pulse in solid metals. We are comparing results drawn from a mathematical model with data measured by connecting temperature probes to a computer on-line. […]
In the context of the ‘Lauree Scientifiche – Scienza dei materiali’ project, highschool students analyze the energy transfers in a kit including a solar cell, two PEM cells (electrolyzer and fuel cell) and a fan, with special attention to the hydrogen stocking process in the reservoir. […]
Mode of operation and examples of using smartphones as accelerometers in the physics lab […]
Last Spring’s sensational news, then proved to be rash, about the discovery of gravitational waves originated after the Big Bang, illustrate some unfair aspects of the methods used by the scientists in divulgating the results of their researches […]
In this note we present some remarks on the prediction of the equilibrium state in a horizontal, rigid, adiabatic cylinder divided into two chambers by an adiabatic piston. The two chambers contain two gases 1 and 2, at different pressures and temperatures. […]
The article shows how the derivatives of the trigonometric functions sine and cosine can be calculated with simple but rigorous geometrical reasoning. […]
