The Structure of Scientific Revolutions
Thomas S. Kuhn
    Written by the man who coined the term "paradigm shift" this book describes the process and the end result.  In essence paradigm shift is a relatively abrupt, fundamental change in the way that a specific conceptual world view is defined.  The revisions tend to supplant earlier views that have served the needs of workers in specific fields, but have eventually proven to be inadequate.  The replacement of Ptolemy's geocentric system by the heliocentric system of Copernicus and the discovery of oxygen are two historical examples used to shed light on the nature of its workings.
