Isaac Newton's early educational background was marked by his time at Trinity College, Cambridge, where he enrolled at 18. His academic environment played a vital role in cultivating his intellectual curiosity and mathematical skills. Newton's interest in mathematics and natural philosophy flourished, leading him to study and challenge established theories. During the Great Plague, Newton returned to his family home, where he developed groundbreaking theories on calculus, optics, and the laws of motion. This period fundamentally shaped his contributions to science and laid the groundwork for his future achievements.
