He also developed calculus, and studied optics and gravity then:
When the Great Plague of London ravaged through the British city beginning in 1665, Issac Newton was a student at Trinity College, Cambridge. As described in Gale Christianson’s Isaac Newton, a few months after acquiring his undergraduate degree in the spring of that year, the 23-year-old retreated to his family farm of Woolsthorpe Manor, some 60 miles northwest of Cambridge. Along with being located a safe distance from the carriers of the horrific disease that was wiping out the population of the city, Woolsthorpe provided the sort of quiet, serene environment that allowed a mind like Newton’s to journey, uninterrupted, to the farthest reaches of the imagination. This period is now known as annus mirabilis – the “year of wonders.”
