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. […]
The concept of pressure should be easy to understand; despite that, I’ve found frequent misunderstandings in students, teachers, and books. Is this quantity related to interaction or to the state of a system? Is it a vector, or scalar (or tensor) quantity? […]
We are reporting the results of a survey concerning the presence of subjects related to Modern Physics in Italian high-school textbooks. Such contents are being slowly introduced into the syllabus of schools experimenting new curricula. […]
In 1855 Maxwell developed a formal analogy between the motion of an incompressible fluid, the electric current in a conductor, and the lines of force of a magnetic field. His analysis represents an example of interdisciplinary study of physical phenomena in the past, […]
The purpose of this article is to get the student acquainted with simple mathematical techniques allowing her (him) to investigate some basic properties of keplerian motion. […]
Thin film interference is the basis of Time-Resolved Reflectivity (TRR), a technique used in condensed matter physics to study phase transformations. Two series of simple experiments are proposed: one employing microwaves, and the other visible and infrared laser light. By the microwave experiments we show the role played by the thickness and the refraction index of the film. […]
Several demonstrations are described, illustrating dynamic interactions between alternating currents and fields. […]
The aim of this paper is to show, with a simple experiment, how a cigarette burns as a consequence of pressure drop in a bottle representing a smoker […]
Two problems are discussed, giving a schematic solution and an evaluation […]

The general problems involved with the introduction in the Italian junior high schools of an integrated course in physical sciences are discussed. The relationship between physics and chemistry teaching and the importance of an innovative laboratory use are particularly emphasized. […]
