His surviving correspondences, notes, and manuscripts contain an estimated 10 million words, enough to fill up roughly 150 novel-length books. There are pages upon pages of scientific and mathematical brilliance. But there are also pages that reveal another side of Newton, a side his descendants tried to keep hidden from the public.
