An educational laboratory activity on phase diagrams based on computer online experiments and problem solving is presented. The phase diagrams are at the base of many technological processes involving materials with peculiar properties with which artifacts of our everyday life are produced. […]
A teacher reports his experience in an integrated ‘physics plus english’ course promoted by the CLIL (Content and Language Integrated Learning) project that introduces mixed teaching of institutional courses and foreign languages in secondary schools. […]
A teaching approach to Newtonian mechanics emphasizing dynamical modelling is presented. The approach extensively uses a software allowing students to simulate motions in one dimension and to relate observational kinematics characteristic to dynamical interaction models. An example of how the software can be used in teaching is also discussed. […]
The most important topics and results of research on friction, from antiquity to now, are outlined: the early laws and theories, from Leonardo to Amontons and Coulomb; the theory of lubrication and the models of rolling friction from 1840 to 1930; […]

Data obtained by simple measurements of the characteristics current-tension of an incandescent commercial bycicle lamp are analized to recognize the electrical transport properties of its tungsten filament, giving the opportunity to explore an important property of the metals in the classroom. […]
A brief report of the history of the discovery of Nuclear magnetic resonance, which underlines the important effect on the post-war world physics in the field of the basic research work on microwaves and electronics done at the MIT ‘Radiation Laboratory’. […]
