Quaderno 23 – Fisica Sognante di Federico Benuzzi (Capitolo 5) […]
Retracing the steps which led to formulate the hypothesis on electromagnetic nature of light, two circuits (RL, RC) in alternating current regimen were observed to measure the constants of vacuum permeability and permittivity, yielding μ0 = (1,27 ± 0,51)·10−6 H/m, […]
In this note is described a very simple experiment to estimate the thickness of the graphite layer deposited on paper by a writing pencil. […]
Measuring the thickness of a soap bubble is an intriguing problem that can be solved – at least with respect to the order of magnitude – with scales of 0.01 grams sensitivity (or better). Solving this problem at secondary school level and up is a motivating activity that requires the students to concretely exercise their inventiveness. […]
A school activity on free fall, aimed at 12-13 year old pupils, is described and discussed. […]
