Richard Feynman

The physicist who did not follow the beaten path

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.

Why is the sea blue?

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. Do you know why?


Violent universe

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.


And they were detected a hundred years later

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.

Statistics in particle physics

The history of particle physics has witnessed many experiments that could illustrate the role of statistics, but few can boast a discovery of such scientific impact and dimensions as the Higgs boson, resulting from a colossal collective and technological endeavour.


Interview with Juan Fuster

Parlem amb Juan Fuster sobre els aspectes més destacats de la física de partícules i sobre l’enteniment entre els científics i els periodistes, una relació que considera necessària.


Interview with Frank Wilczek

Frank Wilczek (New York, 1951) is a rather unconventional individual. To begin with, his outfit does not fit –a hat and tie together with trainers– and this impression is proven true during the conversation, during which, for instance, he refers to «funny electrons» and takes


Time and (a)symmetry

I must confess it: Physics has always filled me with a feeling of respect. I would be lying if I did not admit that thinking about some of its mysteries has tormented me more than once.  That is how I was warned at high school by
