Isaac Newton

Definition

Isaac Newton was a renowned English mathematician, physicist, and astronomer who is best known for his laws of motion and universal gravitation, which laid the groundwork for classical mechanics. His work in the late 17th century also included significant contributions to optics and mathematics, particularly calculus. Newton's innovative use of illustration in his publications, particularly in 'Philosophiæ Naturalis Principia Mathematica', played a crucial role in advancing astronomical knowledge and visualizing complex scientific concepts.
