Beta and gamma rays are able to penetrate into solid bodies. This property of radioactivity can be verified in a very simple and efficacious manner, making an experiment, even in a school laboratory, with poor matter. […]
This article deals how to represent the experimental data with their absolute error with Lotus 123 […]
We propose here a simple realisation of an anemometer, using recycling materials (except for a small milliamperometer). The calibration of the instrument was obtained by means of a ‘fluidometric pendulum’, following the idea proposed by the great hydraulic engineer Domenico Guglielmini (1655-1710) at the end of the 17th century.
