For there to be sound, there must be a vibrating source, a transmitting medium that propagates the vibration at a certain speed, and a receiver that is set into vibration when the wave arrives.
There is no way to force a pendulum to oscillate at a different rhythm, determined exclusively by its length
If we were to use electrodes to extract energy from ourselves, we would collapse because we would have nothing left to keep our hearts beating.
In space, there is not a medium to transmit sound, so the battles going on in space would not be heard.
Any vibrating object produces sound. Chantal Ferrer, director of the Department of Applied Physics of the University of Valencia, explains.
The Swedish Academy has awarded Roger Penrose, Reinhard Genzel, and Andrea Ghez the Nobel Prize in Physics. What is behind this shared award? When did the debate on black holes start? An analysis by Manel Perucho.
Using simple materials like plastic bottles, straws, modelling clay, and syringes you can witness many interesting phenomena relating to air and water pressure.
The historian of science Alexander Koyrè summarised the scientific work of the sixteenth century as a gradual understanding of the works of Archimedes.
Probably of Paleolithic origin and present since the first civilisations, the sling is ancient and ubiquitous not only as a weapon, but also as the paradigm of circular movement.
When a material gets wet, we see it with a darker colour. Professor Inmaculada Pascual Villalobos explains why.
