Pierre-Simon, marquis de Laplace (23 Mairch 1749 – 5 Mairch 1827) wis a French mathematician an astronomer whose wark wis pivotal tae the development o mathematical astronomy an statistics. He summarised an extended the work o his predecessors in his five volume Mécanique Céleste (Celestial Mechanics) (1799–1825). This wark translated the geometric study o classical mechanics tae ane based on calculus, opening up a broader range of problems. In statistics, the so-called Bayesian interpretation of probability was mainly developed by Laplace.
He formulated Laplace's equation, and pioneered the Laplace transform which appears in many branches of mathematical physics, a field that he took a leading role in forming. The Laplacian differential operator, widely used in applied mathematics, is also named after him.
He is remembered as ane o the greatest scientists of aa time, sometimes referred to as a French Newton or Newton of France, with a phenomenal natural mathematical faculty superior to any of his contemporaries.
