Newton’s Principia: The Mathematical Principles of Natural Philosophy

Isaac Newton's "Philosophiæ Naturalis Principia Mathematica," commonly known as the Principia, published in 1687, remains a cornerstone of scientific history. Written in Latin, it spans three volumes, articulating Newton's laws of motion and the law of universal gravitation. Regarded as a pivotal work, it revolutionized physics, shedding light on a previously conjectural science. Newton's empirical approach is underscored by his statement, "Hypotheses non fingo" ("I frame/feign no hypotheses"). The Principia forms the basis of classical mechanics, elucidating Kepler's laws and employing mathematical methods later integral to calculus. Newton's enduring influence is evident, as his principles still govern celestial dynamics and guide modern physical science. The authoritative translation by I. Bernard Cohen and Anne Whitman ensures accessibility, correcting errors and presenting Newton's groundbreaking work in contemporary prose.
