"Математические начала натуральной философии" (Mathematical Principles of Natural Philosophy) is a foundational work by Isaac Newton, published in 1687. It outlines the laws of motion and universal gravitation, establishing a framework for classical mechanics. Newton's work revolutionized the understanding of physical phenomena and laid the groundwork for modern physics. The book is divided into three main sections: the laws of motion, the motion of celestial bodies, and the principles of fluid mechanics. Newton's use of mathematics to describe natural laws marked a significant shift in scientific thought, influencing future scientists and philosophers, including Albert Einstein and Galileo Galilei.
