Science for All has reached its 250th publication. To celebrate this occasion, Fondo de Cultura Econmica brought together in this anthology, fragments of the books that were published throughout 30 years in its 11 thematic areas, on which the core subject focuses on the origin of things: the origin of the universe, the chemical elements, the life on earth and the human being, without leaving behind the science in itself. The origin of science, is just an invitation to get to know about the scientific thinking and continue reading each and every one of the 250 works that are part of this collection.
