About the author
Born in Normandy in 1749, Pierre-Simon Laplace rose to become one of the most influential scientists in France. He worked across mathematics, astronomy, and physics, and became especially famous for showing how Newton’s law of gravitation could explain the motions and apparent irregularities of the solar system with remarkable precision.
Laplace’s major books, including Mécanique céleste and Théorie analytique des probabilités, helped set the course for modern celestial mechanics and probability theory. Ideas associated with his name still appear throughout science and mathematics today, from the Laplace transform to Laplace’s equation.
He also played a public role during a turbulent period in French history, serving in government and earning honors under Napoleon and later regimes. Laplace died in Paris in 1827, but his reputation as one of the great mathematical minds of his age has endured ever since.
