The International Atomic Time, the leap second concept, the modern techniques used to obtain a correct speaking clock and the reasons that corrupt the delivery of the time check via digital broadcasts are briefly described, […]
Anno XXVI - n.2 - aprile/giugno 1993 La Dinamica Molecolare e l’Insegnamento della Fisica della Materia Condensata nelle Scuole Superiori
In this paper we discuss molecular dynamics, a numerical technique successfully employed since thirty years in research to solve the equations of motion in many body systems. We propose using molecular dynamics as a tool in high school teaching of condensed Matter Physics. […]
Anno XXVIII - n.1 - gennaio/marzo 1995 La Fisica Moderna nei libri di testo
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. […]
