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. […]
The concepts of spontaneous and stimulated emission are well known from Einstein?s 1917 paper on radiation, but his theory of radiation comprises many other concepts-the paper is a treasure trove of physics. […]
The aim of the work is to provide a panoramic vision on electromagnetic radiation hazards, in school laboratories. Some procedures of prevention are also detailed with exposure limits and treshold values proposed by italian rules or international board, that can be used for didactical purposes also. […]
As we realized after a detailed monitoring that students can easily get lost in solving problems of physics, this article propose a new didactic tecnique .nearer to the researcher work whose purpose is to stimulate students to sustain their interest in physics, […]
