To my mind, that vision of calculus is far too blinkered. Calculus is not just the work of Newton and Leibniz and their successors. It started much earlier than that and it’s still going strong today. Calculus, to me, is defined by its credo: to solve a hard problem about anything continuous, slice it into infinitely many parts and solve them. By putting the answers back together, you can make sense of the original whole. I’ve called this credo the Infinity Principle.
