The System of the World

work by Laplace
Also known as: “Exposition du système du monde”

Quick Summary

The System of the World is a work by Pierre-Simon Laplace, a French mathematician and astronomer. Published in 1796, it aimed to explain all the phenomena of the solar system to a general audience using the principles of universal gravitation.12

Laplace's work also introduced his "nebular hypothesis," a theory suggesting that the solar system originated from a cooling and contracting gaseous nebula. This idea was influential in the development of evolutionary theories in natural science. The book also explored the stability of the solar system, demonstrating that planetary orbits are inherently stable and self-correcting due to gravitational interactions, rather than requiring divine intervention. Laplace also applied probability theory to scientific data, including astronomical observations.123
