@syncfaiil: Sir Isaac Newton was only 23 when the core ideas behind the universal law of gravitation took shape. In 1665-1666, while Cambridge was closed because of the plague, the young Newton retreated to his family home in Woolsthorpe. In that period of intense solitary work he developed the foundations of calculus, made major advances in optics. And formulated the concept that the same force pulling an apple to the ground also keeps the Moon in orbit and governs the motions of the planets. Those insights later became the law of universal gravitation published in the Principia in 1687. The achievement remains one of the most remarkable bursts of scientific creativity in history, accomplished by a mathematician still in his early twenties. #newton #physics #interesting #Science #fyp
