The one that blow my mind the most was the simultaneous invention of calculus. Modern Calculus can be reasonably thought of as the most important mathematical leap forward of the last 1000 years. If there was ever an invention that can be considered a piece of unquestionable genius, then that's calculus. And somehow, it was simultaneously invented by 2 different people within a few years of each other. https://en.wikipedia.org/wiki/Leibniz%E2%80%93Newton_calculus_controversy https://en.wikipedia.org/wiki/Leibniz%E2%80%93Newton_calculu...
