The Chronologers' Quest

Book excerpt: The debate over the age of the Earth has been ongoing for over two thousand years, and has pitted physicists and astronomers against biologists, and religious philosophers against geologists. The Chronologers' Quest tells the fascinating story of our attempts to determine the age of the Earth. This book investigates the many novel methods used in the search for the Earth's age, from James Ussher and John Lightfoot examining biblical chronologies, and from Comte de Buffon and Lord Kelvin determining the length of time for the cooling of the Earth, to the more recent investigations of Arthur Holmes and Clair Patterson into radioactive dating of rocks and meteorites. The Chronologers' Quest is a readable account of the measurement of geological time. It will be of great interest to a wide range of readers, from those with little scientific background to students and scientists in a wide range of the Earth sciences.
