Abstract

John Granville's first book is unique on several counts. First, it's not simply a history of science, but rather a history of our evolving unerstanding of motion. It's unique in the detailed explanations given to common scientific riddles-explanations aimed to help students avoid catastrophic collisions with these concepts in college. It's unique in that it resents the philosophies on which the major scientific paradigm shifts rest. It's unique in its presentation from Thomas Kuhn's point of view (i.e., his concept of world view and paradigm shifts as presented in his classic work The Structure of Scientific Revolutions). The book begins with an informal discussion of Kuhn's notion of world view, and various concepts relevant to his thesis concerning the nature of scientific revolutions; but, the Discovery of Motion proper begins with ancient Egyptian and Greek preparations for Aristotle (here the dialectic of Parmenides and Plato are given special attention). A survey of Aristotle and his science of motion follows (i.e., his theory of nature and natural philosophy). Included in this part of the book are the works of such notables as Archimedes and Ptolemy. The Copernican revolution, including the works of Galileo, Kepler and Newton is, of course, presented from the viewpoint of Kuhn's paradigm shift. Four chapters concerning Newtonian motion are the highlight of the first half of the book. It is here Granville's original aim, of explaning puzzling scientific phenomena to young students, is realized-but now this material serves another purpose. These chapters not only clarify Newton's world view but expose phenomena that were virtually invisible to the peripatetics...and will eventually expose reasons for the ambivalence and frustration that accompany scientific revolutions. Granville then turns to philosophical developments that led to our modern view of the world. This part of the book covers the evolution of empiricism from Bacon to Hume (with Descartes' rationalism thrown in for contrast). Kant's epistemology concludes this philosophical survey, deliberately leading the plot back toward the classical viewpoint. Finally, developments of the nineteenth century that led to the so-called Second Scientific Revolution are considered. The final chapter is a unique presentation of Einstein's relativity theory, where the incompatibility of this theory with Newtonian physics, and the reason why relativity must take precedence, are discussed. Granville compares the opposition to the Copernican revolution with twentieth century opposition to the Einsteinian revolution. The book reveals that, after building detailed understanding of classical Newtonian phenomena, opposition to a shift of world view is an understandable human reaction.
