1665 in Science

Newton / Cambridge / Wollsthorpe Manor

In June 1661, he was admitted to Trinity College, Cambridge. Soon after Newton had obtained his BA degree in August 1665, the university temporarily closed as a precaution against the Great Plague. Although he had been undistinguished as a Cambridge student, Newton’s private studies at his home in Woolsthorpe over the subsequent two years saw the development of his theories on calculus, optics, and the law of gravitation.

Woolsthorpe Manor is birthplace and was the family home of Sir Isaac Newton. Newton returned here in 1666 when Cambridge University closed due to the plague, and here he performed many of his most famous experiments, most notably his work on light and optics.This is also said to be the site where Newton, observing an apple fall from a tree, was inspired to formulate his law of universal gravitation

https://en.wikipedia.org/wiki/Method_of_Fluxions

Method of Fluxions (latin De Methodis Serierum et Fluxionum) [1] is a book by Isaac Newton. The book was completed in 1671, and published in 1736. Fluxion is Newton’s term for a derivative. He originally developed the method at Woolsthorpe Manor during the closing of Cambridge during the Great Plague of London from 1665 to 1667, but did not choose to make his findings known (similarly, his findings which eventually became the Philosophiae Naturalis Principia Mathematica were developed at this time and hidden from the world in Newton’s notes for many years).
