Imagine the Solar System as a collection of different bodies—planets, comets…—subject only to the Sun’s gravitational pull. Classical mechanics then tells us that their orbits can trace only three types of curve: ellipses, hyperbolas and parabolas.

The birth of "deterministic chaos" grew out of Henri Poincaré's entry for a prize offered by King Oscar II. The French mathematician's paper would go down in history for containing a major error—one that proved extraordinarily fruitful for science.
