Who invented calculus?

Calculus is an extremely powerful mathematical toolbox that can be used to deal with phenomena in flux. This includes the flow of water and expansion of the cosmos. It would be better called ‘fluxions whoinvented.info‘, which Isaac Newton, one the two 17th-Century mathematicians who were considered its inventors, coined. The other being Gottfried Leibniz. Newton didn’t see it that way. He had in secret invented it in 1660s and was shocked when Leibniz, who independently discovered them, made similar methods public a decade later.

Newton launched an unjustified campaign against Leibniz’s character, but he could not stop Leibniz’s adoption of his name for the technique (from Latin for “counting stones”). Now it is known that basic concepts in calculus were explored long before Newton. Archimedes, for example, showed how to divide the area enclosed in curves into small strips. This trick is used in integral calculus to calculate the total effect of small changes. But, Newton and Leibniz’s predecessors didn’t realize the full power of their work.
