An introduction to the central facts, evidence and issues of modern science. It takes the reader through the basics and the fundamental issues of the crucial areas of modern science, from the birth of the universe to the evolution of our own species, the nature of human behaviour and the workings of our minds. It does not only provide an overview, but explains how these areas link up, what evolutionary theory has to say about the way we think, how sub-atomic particles came into being in the Big Bang, and atoms in the stars.
