calculus from Newton’s.9 Newton had apparently made his discovery in 1666, but he did not publish it till 1692; Leibniz published his differential calculus in 1684, his integral calculus in 1686.10 There remains no doubt that Newton was first in the discovery, that Leibniz reached his own discovery independently, that he antedated Newton in publishing the discovery, and that Leibniz’ system of notation proved superior to Newton’s.
