A variety of phenomena in which sliding friction between bodies having some degree of elasticity is present exhibit stick-slip motion. We describe a simple device that allows to analyse this kind of dynamics and we present a wide set of possible experimental observations and measurements. […]
Reactions to the science of global warming have followed a similar course to those of other inconvenient truths from physics. […]
The concept of verticality is discussed with reference to its different meanings, e.g. the direction that points towards the zenith, the one which is parallel to the direction of free fall or is perpendicular to a level ground, etc. […]
The actors on the stage of science after Newton’s age could be divided into two groups: the so called “geometers” involved in improving mechanics and gravitation from a mathematical point of view, and the “physicists” more interested in investigating subjects like magnetism, […]
