Curt Stager is the rarest of scientific writers, he can both write and present good science. The book, while detailed is eminently readable and logical. It takes the reader from atoms to outpace and, by definition from outspace back to atoms. The book answers many fundamental questions about the life of our planet and the lack of life that exists within our own bodies. At the book's end some nearly spiritual reflections penetrate the reader and pose additional questions about the familiarity of our won existence. Are we actually living or merely a collection of non living entities that we have conveniently refered to as atoms Ponderable, but unanswered by this publication, just the sort of thought experiment that I so richly enjoy. Please read the book and think, think about who and what you are.
