Although this man is not Albert Einstein, one of this physicist's ideas is similar to a doubly eponymous equation that models Brownian Motion, called the Fokker-Planck Equation. For ten points, name this French physicist who created the Twin Paradox, a physicist with a namesake formula, function, law, and equation.
