The Principia

The Principia by Isaac Newton is a monumental work that lays out in mathematical terms the principles of time, force, and motion that have guided the development of modern physical science. This completely new translation, the first in 270 years, includes extracts from the earlier editions, corrects errors found in earlier versions, and replaces archaic English with contemporary prose and up-to-date mathematical forms. Newton's principles describe acceleration, deceleration, and inertial movement; fluid dynamics; and the motions of the earth, moon, planets, and comets. The Principia revolutionized the methods of scientific investigation and set forth the fundamental three laws of motion and the law of universal gravity, effectively ending controversy concerning the Copernican planetary system.
