Isaac Newton by Kneller Godfrey Kneller (Public Domain) Isaac Newton (1642-1727) was an English mathematician and physicist widely regarded as the single most important figure in the Scientific Revolution for his three laws of motion and universal law of gravity. Newton's laws became a fundamental foundation of physics, while his discovery that white light is made up of a rainbow of colours revolutionised the field of optics. Early Life Isaac Newton was born on 25 December 1642. His family ... The Law of Gravity was formulated by Sir Isaac Newton in the 17th century. Born in 1642, Newton's groundbreaking work, "Mathematical Principles of Natural Philosophy" in 1687, unveiled this law, explaining the attraction between masses. Influenced by Galileo, Newton's contributions revolutionized physics and left an enduring legacy in scientific understanding., Explainers, Times Now Sir Isaac Newton discovered gravity in 1687, realizing the same force that makes apples fall from tree limbs also keeps the Moon in orbit. Among Sir Isaac Newton's many contributions to science was the discovery of gravity. one of the fundamental forces of the Universe
