The Mathematical Principles of Natural Philosophy

Mathematical Principles of Natural Philosophy often referred to as simply the Principia is a work in three books by Isaac Newton in Latin first published 5 July 1687. After annotating and correcting his personal copy of the first edition Newton published two further editions in 1713 and 1726. In Principia Isaac Newton laid out in mathematical terms the principles of time force and motion that have guided the development of modern physical science. Even after more than three centuries and the revolutions of Einsteinian relativity and quantum mechanics Newtonian physics continues to account for many of the phenomena of the observed world and Newtonian celestial dynamics is used to determine the orbits of our space vehicles.
