## 1749 – Laplace – bio

Pierre-Simon Laplace was born in France in 1749 and was a mathematician and astronomer. His greatest work was a five volume set called, “Celestial Mechanics” which he wrote over a twenty six year period from 1799 to 1825. In addition to summarizing the state of astronomy at the time, he transformed Newton’s geometrical mechanics to one based on calculus. In 1786 he developed a proof that solar system orbits were stable. In 1812 he published a work on probability theory based on previous work by Bayes.
