What was discovered

While studying the stability of the solar system he discovered homoclinic orbits and that small initial differences produce entirely different behaviours. The first appearance of deterministic chaos and the origin of the qualitative theory of differential equations.

The memoir awarded the prize in 1889 contained an error; correcting it revealed the chaos.

What it led to

  • dynamical systems
  • chaos theory (Lorenz)
  • KAM theory
  • ergodic theory

Built on

  • Newtonian and Laplacian celestial mechanics
