This article presents a comprehensive biography of Sir Isaac Newton, one of the most influential scientists in human history whose work fundamentally transformed humanity's understanding of the physical universe. Based on analysis of historical documents, scientific treatises, and biographical accounts, this article reconstructs Newton's trajectory from a solitary Cambridge scholar to President of the Royal Society and Master of the Mint. Particular attention is devoted to his groundbreaking contributions to physics, mathematics, optics, and astronomy, as well as his lesser-known pursuits in alchemy, theology, and chronology. The complex personality of Newton—secretive, intensely focused, and intellectually relentless—emerges as inseparable from the revolutionary ideas that laid the foundation for classical mechanics and dominated scientific thought for three centuries.
