Aquest llibre està adreçat a un primer curs de mecànica per a l’enginyeria. S’estudia la mecànica newtoniana. Una mecànica clàssica no relativista i, per tant, aplicada a objectes no extremadament petits ni excessivament ...

Our first objective was to detect misconceptions about the microscopic nature of sound among senior university students enrolled in different engineering programmes (from chemistry to telecommunications). We sought to ...

We propose a novel approach to detect gravitational waves based on a semi-rigid detector. The approach relies upon the time delay that the light takes to travel from a fixed mirror at the end of a rigid bar to a nearby ...

The group of rigid motions is considered to guide the search for a natural system of space-time coordinates in General Relativity. This search leads us to a natural extension of the space-times that support Painlevé–Gullstrand ...

In an effort to contribute to a better understanding of General Relativity, here we lay the foundations of generalized Newtonian gravity, which unifies inertial forces and gravitational fields. We also formulate a kind ...

Every planning of an efficient teaching has the aim of achieving satisfactory learning outcomes. From a constructivistic point of view, it is a commonly accepted fact that such a planning has to take into account the ...
