The shape of some astronomical bodies of different size is taken into consideration and qualitatively explained on a gravitational-electromagnetic interaction ground. […]
QR codes have been used to communicate clues of a Christmas scientific treasure hunt for students of first year of Science oriented High School. […]
An electronic way to measure the mechanical torque developed by an electric motor is noted. The measurement is made solely on the stator. […]
One of the most innovative and fruitful contribution to theoretical physics by Tullio Regge (1931-2014) is presented. Known as “Regge Calculus”, it consists of a formulation of the General Relativity developed in the celebrated paper “General Relativity without Coordinates”, published in 1961 in the Nuovo Cimento. […]
The paper presents three simple acoustic experiments carried out using a smartphone and some objects available in any kitchen. […]
The conditions why objects rolling down different inclined tracks cover different distances in equal interval of time are studied. We want to demonstrate that the time taken by a ball to cover a chord of a circumference because of gravity, does not depend on the length of the chord itself. […]
