Nature’s Clocks: How Scientists Measure the Age of Almost Everything

by Doug Macdougall
Berkeley (CA): University of California Press, 2008. 288 pages.

“In Nature’s Clocks,” writes reviewer John W Geissman, “Doug Macdougall provides an exceptionally well-written and engaging description ... of how we know what we know about absolute age determinations and thus about our attempts to unravel the uncertainties of deep time. This book is very suitable for a general audience interested in the history of our planet, including the details of how geoscientists, based on absolute age determinations, infer the ages of specific geologic events ... and the durations of specific processes.”
