Each of the three volumes of Science in Dispute examines about 30 topics of scientific controversy in an in-depth, pro-con format. Each volume also includes three or four historic disputes - issues that have been long settled but which were significant in the history of scientific and human development; these include topics like Is Earth the centre of the universe? and Are Earth's continents stationary throughout geologic time? The essays are written by scholars and experts in their respective fields. Each topic has an introduction, in which the general terms of the debate are delineated, and two essays that take up opposing viewpoints and examine the issue in a thorough yet readable manner.
