[The conceptual revolutions about nature as imposed by 20th century physics]. / Las revoluciones conceptuales acerca de la naturaleza impuestas por la física del siglo XX.

A catalogue is offered of the thirteen conceptual--and observational--revolutions which took place in twentieth century Physics, those which should be considered the most revelant for their significance in the scientific and philosophical thought about Nature as established along that century. The are organized in the three areas where they were originated: Relativity, Quantum Physics and Cosmology. Several of these conceptual revolutions appeared in Physics explicitly, while the rest only happened to arise in a latent way. The ones and the others are remarked in this contribution with philosophical expressions and through the world horizon, a perspective which opens in a general manner each revolution to the whole of the scientific and philosophical of the past century.
