Who is a French scholar that specialized in Physics and astronomy?
Pierre-Simon Laplace Pierre-Simon, marquis de Laplace ( ; ] ; 23 March 1749 – 5 March 1827) was an influential French scholar whose work was important to the development of mathematics, statistics, physics and astronomy. He summarised and extended the work of his predecessors in his five-volume "Mécanique Céleste" ("Celestial Mechanics") (1799–1825). This work translated the geometric study of classical mechanics to one based on calculus, opening up a broader range of problems. In statistics, the Bayesian interpretation of probability was developed mainly by Laplace.
