Anno XLIX - n.1 - gennaio/marzo 2016 La suscettività magnetica al variare della temperatura
We present an experiment to measure the temperature dependence of magnetic susceptibility of a dia-magnetic material such as pyrolityc graphite. Pyrolityc graphite is a typical diamagnetic material and can levitate in a strong magnetic field. the levitation height was changed by varying the pyrolityc graphite temperature using a lighter. […]
Anno XXVII - n.1 - gennaio/marzo 1994 La Teoria corpuscolare della radiazione di Einstein: “Una audace ipotesi” utile a superare la contrapposizione tra continuità e discontinuità nella descrizione della realtà fisica.
This research intended to analyse Einstein’s paper on granular structure of radiation, more by the light of Einstein’s later writings. The following topics will be discussed the reasons for his quantum theory’s formulation and the connection between Planck’s radiation theory and Einstein’s ideas. […]
Anno XXXIV - n.4 - ottobre/dicembre 2001 La Terra nel caos
The evolution in time of the motion of the Earth is briefly examined with reference to chaos theory. […]
Anno XXIX - n.1 - gennaio/marzo 1996 La torre di Babele
We received a very interesting document from historic point of view, that, if authentic, would witness for an extraordinary development of ancient Babylonian physics, never before supposed by historians of science. “Fisica nella scuola” does not take any position about document’s authenticity and only publishes its translation, […]
Anno XXIII - n.4 - ottobre/dicembre 1990 La valutazione dell’ingrandimento angolare negli strumenti ottici
This paper analyses an experimental method by which laws of angular magnification, for common optical instruments, are pointed out. Kepler’s and Galilei’s telescopes simple and compound microscopes are analysed with the aid of a TV camera and a monitor. Image sizes are measured on the monitor before and after instrument magnification; […]
