“A teacher in a fourteenth-century Kerala village invented the essential move of calculus — taming the infinite with controlled error — and we know it only because his students' students spent two hundred years quoting him, proving him, and writing him down.”

“You can never finish computing π or a sine — so stop trying to finish. Describe the unending process exactly, as an infinite series, and control the error of stopping wherever you stop. That is the central machinery of calculus, built two and a half centuries before Newton and Leibniz.”
