The second book of the Series De las Ciencias a la Filosofía has been published.

The worlds of the infinitely small and of the infinitely large, as distant from each other as they are, remain closely connected. Modern Cosmology, which deals with the origin and the end of the universe, cannot be explained without taking particle physics into account.

This book describes a double journey. It begins first from the human size towards the very smallest, crossing the limits of life and ending up in the building blocks of matter. The second part of the journey heads towards the planets, the starts and the galaxies, to reach the end of the universe, its origin and its possible end, as well as the most ardent question in modern physics, which remains unanswered: did anything happen before the Big Bang?
