Isaac newton (1642~ 1727), a British scientist, is one of the founders of modern science. Born in a poor peasant family, he became a great scientist with profound knowledge and original spirit through his own efforts. He made great scientific discoveries in astronomy, optics, mechanics, heat and mathematics. His Mathematical Principles of Natural Philosophy is an epoch-making scientific masterpiece. His theories, such as the law of universal gravitation, provide a valuable foundation for the development of modern science.

Newton was the greatest physicist before Einstein, and his theory laid the foundation of classical physics. In his long life, he made many great contributions: he founded calculus, which provided a powerful mathematical tool for the research of modern natural science and the development of engineering technology; He decomposed sunlight and discovered the secret of light color; He summed up three basic laws of mechanical motion, which laid a theoretical foundation for solving many mechanical motion problems. He discovered the law of gravity and established the theoretical system of celestial mechanics, which greatly deepened human understanding of the universe ... Newton was undoubtedly a great mentor to help people understand the objective world.
