# Which major work by Isaac Newton laid the foundations of classical physics, deeply influencing the Age of Enlightenment?

Principia Mathematica

In his monumental work, "PhilosophiÃ¦ Naturalis Principia Mathematica," published in 1687, Isaac Newton formulated the laws of motion and the universal law of gravitation. These discoveries not only revolutionized the way the universe was understood but also served as a cornerstone of the Age of Enlightenment, demonstrating that the natural world was governed by universal and comprehensible laws. Newton thus paved the way for the expansion of the scientific method and the pursuit of rational knowledge, influencing generations of thinkers.
