Ask HN: Did Leibniz beat Newton?
In The Information, Jame Gleick posits that Leibniz "triumphed" over Newton during Babbage's time, becoming the preferred Calculus. Is today's Calculus more Leibniz than Newton?
However, the notation that most people use to denote infinitesimals and differentiation is Leibniz's notation: http://en.wikipedia.org/wiki/Leibnizs_notation
