Time Matters provides an invaluable insight into the
background behind some of the key concepts we use in Earth science
today. It shows the historical context in which these ideas were
developed, the important contributions of individual scientists and
thinkers, and how these ideas continue to shape our view of science
and the world in which we live.
The book covers subjects such as the age of the earth,
catastrophism vs uniformitarianism, evolution vs creationism,
plutonism vs neptunism, continental drift and plate tectonics. It
explores the people involved, their ideas and the scientific and
religious power politics involved in the development. It is
effectively partly a review of the way in which science works or
does not work. The text includes questions and comment boxes which
help the reader to appreciate/understand the ideas and concepts
that have been included and their problems, strengths or
weaknesses.
* Accessible introduction – does not assume prior
knowledge
* Teaches scientific thought – particularly the use of
evidence
* Topic based – uses a set of key geological theories
This book is written for anyone with an interest in geology and
the history of science, but will be particularly valuable to
university or high-school students beginning a study of earth
science for the first time.
