> Initially, Newton and Leibniz came up with objects called infinitesimals. It made their equations work, but by today’s standards it wasn’t sensible or rigorous. It would be great if mathematics was widely presented and taught in this messy, practical, human, truthful way rather than the purist, mystical, mythical manner. Calculus wasn't "discovered", it was painstakingly developed by some blokes that were trying to solve physical problems.
