The quest to pinpoint the age of the Earth is nearly as old as humanity itself. For most of history, people trusted mythology or religion to provide the answer, even though nature abounds with clues to the past of the Earth and the stars. In A Natural History of Time, geophysicist Pascal Richet tells the fascinating story of how scientists and philosophers examined those clues and from them built a chronological scale that has made it possible to reconstruct the history of nature itself. By the end of the twentieth century, new tools such as radiometric dating had demonstrated that the solar system is 4.5 billion years old, and the universe itself about twice that, though controversial questions remain. The quest for time is a story of ingenuity and determination, and like a geologist, Pascal Richet carefully peels back the strata of that history, giving us a chance to marvel at each layer and truly appreciate how far our knowledge - and our planet - have come. «
