Thankfully, scientist Edmond Halley's funded the printing. -u/Hbunny3177

Isaac Newton poked his eye with a sewing needle to learn more about light by seeing how altering the shape of his eye would change his perception - he recorded seeing colored circles and other visual phenomena. -u/yogurtpimple

The familiar story that Isaac Newton was inspired to research the nature of gravity by an apple hitting his head is almost certainly apocryphal. All Newton himself ever said was that the idea came to him as he sat "in a contemplative mood" and "was occasioned by the fall of an apple". -u/Movie_Advance_101

In 1665, the University of Cambridge temporarily closed due to the Bubonic plague. Isaac Newton had to work from home, where he used that time to develop calculus and the theory of gravity. -u/Jaredrap

Robert Hooke, despite pioneering the experimental method and discovering many elements of gravitational theory first, was almost entirely erased from history by Sir Isaac Newton because they did not like each other and Newton lived 25 years longer, allowing him to edit history to his favor. -deleted user
