Archival Overview

'The French Newton' whose Traité de mécanique céleste proved the gravitational stability of the solar system, proposed the nebular hypothesis of planetary origin, and defined determinism (Laplace's Demon).

Biographical Record

Pierre-Simon, Marquis de Laplace (1749–1827), came from Normandy to Paris with a recommendation from D'Alembert. In his monumental five-volume Traité de mécanique céleste (1799–1825), Laplace applied calculus to the entire solar system, demonstrating that orbital perturbations are periodic and self-correcting, proving the gravitational stability of the universe.

When Napoleon famously asked why his book did not mention God as the creator of the solar system, Laplace replied: 'Sire, I had no need of that hypothesis' (*Je n'avais pas besoin de cette hypothèse*). In his Exposition du système du monde, he formulated the nebular hypothesis of star and planet formation and anticipated black holes. In mathematics, he revolutionized Bayesian probability and the Laplace transform.
