This book is a journey through the history of science in which characters such as Aristotle, Ptolemy, Alfonso X, Copernicus, Brahe, Kepler, Galileo, Newton, Herschel, Newton or Hubble appear. The work reviews the appearance of writing, which is probably the greatest invention in the history of humanity because it allowed the transmission of knowledge and acquired experiences to following generations; the basic tools to study the cosmos are also explained: the measurements of time and space, mathematics, essential elements to determine the trajectories of the planets and the Sun, which is the foundation of astronomy; it tells us about the Universe and the oldest ideas about how it was created; about life from the evolution of the species by Charles Darwin to genetics, how this science (Mendel) emerged and how the discovery of the structure of DNA, and its sequels (Human Genome Project, genetic engineering, biotechnology) were reached; and, finally, it deals with another great conquests of humanity related to science: technology.
