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.
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.
Richard Phillips Feynman (1918–1988) was certainly a curious character, as he himself remarked in the subtitle of his anecdotal books (Feynman, 1985; Feynman, 1988). Not only was he one of the most brilliant and original physicists of the twentieth century, one of the few scientists who opened up new and broad avenues in his discipline.
When a large quantity of water is observed, as happens in the sea, we notice a blue color that can vary depending on the mass of water we are observing. Professor Inmaculada Pascual Villalobos explains why.
We see the sky and admire its regularity and stability, its apparent immutability. We have always done so; it does not come as a surprise, since humans have always been startled by any change in the sky, associating it with omens or the mood swings of gods. At that time, they might call these changes «new stars», even if they were, for example, a supernova explosion, as in the case of Tycho’s supernova in the sixteenth century.
En el marc de la teoria general de la relativitat, Einstein va postular l’existència de les ones gravitacionals, encara que pensava que mai es podrien detectar.
Interview with Mario Bunge, philosopher and physicist.
James Clerk Maxwell proved that electricity and magnetism are only different manifestations of the same physical substrate, electromagnetism.
