"Radioactivity is like a clock that never needs adjusting," writes Doug
Macdougall. "It would be hard to design a more reliable timekeeper." In Nature's
Clocks, Macdougall tells how scientists who were seeking to understand the past
arrived at the ingenious techniques they now use to determine the age of objects
and organisms. By examining radiocarbon (C-14) dating--the best known of these
methods--and several other techniques that geologists use to decode the distant
past, Macdougall unwraps the last century's advances, explaining how they reveal
the age of our fossil ancestors such as "Lucy," the timing of the dinosaurs'
extinction, and the precise ages of tiny mineral grains that date from the
beginning of the Earth's history. In lively and accessible prose, he describes
how the science of geochronology has developed and flourished. Relating these
advances through the stories of the scientists themselves--James Hutton, William
Smith, Arthur Holmes, Ernest Rutherford, Willard Libby, and Clair Patterson--
Macdougall shows how they used ingenuity and inspiration to construct one of
modern science's most significant accomplishments: a timescale for the Earth's
evolution and human prehistory.
