Who is Isaac Newton from Coming of Age in the Milky Way and what is their importance?

Isaac Newton, the man who made his mark on physics when he developed his theory on gravitation, is one of the book's main subjects. The author notes Newton's destruction of Aristotle's concept of a dual sky, and he makes special mention of his search for God. Newton was also interested in mysticism, alchemy, and magic. According to Ferris, he was the best kind of scientist—one who was open to God, magic, and science...... someone who believes what could be proven to him and left no stone unturned in his search.
