Anno XLVII - n.4 - ottobre/dicembre 2014 Teorie fisiche: forma e sostanza. Un esempio
Beginning of the 19th century, aether and relativity: Lorentz was looking for space-time transformation rules fitting with the covariance of Maxwell?s equations under the change from aether to Earths reference frame. Meanwhile, Einstein was stating the identity of the laws of physics in any inertial frame and the rules of invariance of the speed of light in vacuum, […]
Anno XXXVII - n.2 - aprile/giugno 2004 Termodinamica e storia: un’esperienza didattica
Teaching thermodynamics through an historical approach improves the comprehension of the basic concepts and favors the interaction between teachers of different subjects. The paper reports on a cycle of seminars on the history of thermodynamics that were held in a secondary school of Palermo, […]
Anno XXIII - n.4 - ottobre/dicembre 1990 TERMOGRAFO: un sistema per misure di temperatura on-line nel laboratorio didattico
We describe a temperature data acquisition system for the educational laboratory. Real-time plotting of the outputs of up to 4 sensors allows to easily perform traditional and non-traditional experiments, for example on non-equilibrium states. We suggest a few experiments and discuss the educational uses of the system. […]
Anno LIV – n.4 – ottobre/dicembre 2021 Termometro assoluto con diodi
An electronic linear PTAT (Proportional To Absolute Temperature) thermometer for didactical purposes is discussed and suggested as a laboratory instrument. Building this device helps students go deep into semiconductor physics. […]
Anno XXXI - n.1 - gennaio/marzo 1998 Tipi diversi di costanti in fisica e apprendimento significativo della disciplina
Data derived from teaching experience point to some problems referred to the conceptualization of constants that appear in relationship between physical magnitudes. Some significative problems are identified. Two general hypotheses and four derived hypotheses are formulated. In order to get more information some questionnaires are prepared. […]
Anno XXXV - n.2 - aprile/giugno 2002 Titius e Bode contro Keplero: un’attività didattica sul concetto di legge fisica
The law of Titius and Bode is presented and the meaning of the word ‘law’ is discussed. A comparison is drawn with Kepler’s third law and several school applications are examined. […]
Anno XL - n.3 - luglio/settembre 2007 Transizioni di fase e super-raffreddamento con celle Peltier
We propose an apparatus for teaching experimental thermodynamics in undergraduate introductory courses, using thermoelectric modules and a real-time data acquisition system. Although it is low cost, the device provides an easy approach to investigating liquid-solid and liquid-vapour phase transitions and metastable states (supercooling). […]
