|Henri Poincaré mathematics
Small changes to even a simple solar system governed by Isaac Newton’s laws cause intricate and unpredictable effects, according to an analysis by Henri Poincaré, the French mathematician. * Henri Poincaré, the mathematician, realized that minor differences in initial conditions can result in major differences in the universe where planets could run around like ants.
The three-body problem
Poincaré tried but did not solve the three-body problem —where three planets are subject to only their own gravitational attractions —because he found even when everything was deterministic and nothing was random that such a system was unpredictable.
Many disciplines lack discipline. Too often, the cost of explaining would exceed the value of the explanation.
