Thomas Kuhn (1922-1996) argued that scientific advancement is not evolutionary but rather is a series of peaceful interludes punctuated by intellectually violent revolutions and in those revolutions one conceptual world view is replaced by another. The University of Chicago Press has released The Structure of Scientific Revolutions to the benefit of all students of the history of science, philosophy and the impact of science on society (and society on the development of science). If every there were a true classic on the history and development of science that is must reading for each new generation it is Kuhn's benchmark work The Structure of Scientific Revolutions.
