“THE GREATEST WORK IN THE HISTORY OF SCIENCE” (PMM).

 

FIRST EDITION, Continental issue (three-line imprint). One of the most important works in the history of science, "perhaps the greatest intellectual stride that it has ever been granted to any man to make" (Einstein). Two apparently concurrent issues can be distinguished, identified by their title in uncancelled or cancelled state. One was distributed by Halley and Newton themselves through a number of unnamed booksellers, the other was largely turned over to Samuel Smith for distribution on the Continent (as here). This Continental issue is considerably rarer. 

 

The Principia clarifies the universal physical laws of gravitation and motion which underpin phenomena described by Newton’s predecessors Copernicus, Galileo, and Kepler. He establishes the mathematical basis for the motion of bodies in unresisting space (the law of inertia), the motion of fluids and the effect of friction on bodies moving through fluids, and sets forth the law of universal gravitation and its unifying role in the cosmos.  "For the first time a single mathematical law could explain the motion of objects on earth as well as the phenomena of the heavens... It was this grand conception that produced a general revolution in human thought, equalled perhaps only by that following Darwin's Origin of the Species” (PMM).
