He touched every corner of mathematics when it was still possible to know the whole field — and in doing so, stumbled onto chaos. Poincaré's work on the three-body problem revealed that deterministic systems could spin into unpredictability, founding what we now call chaos theory.
Biography
About
Born 29 April 1854, Jules Henri Poincaré trained as a mathematician, physicist, and engineer, then proceeded to leave his mark on pure math, applied math, celestial mechanics, and the philosophy of science in equal measure. His research on the three-body problem led him to discover chaotic deterministic systems, laying the groundwork for chaos theory; he created the field of algebraic topology, introduced automorphic forms, and in the early 20th century posed the Poincaré conjecture — unsolved for a century until Grigori Perelman cracked it in 2002–2003. He was first to present the Lorentz tra…

Henri Poincaré
said
The very possibility of the science of mathematics seems an insoluble contradiction.
— Ch. I: On the Nature of Mathematical Reasoning (1905) Tr. George Bruce Halstead
Henri Poincaré
said
There is no science apart from the general. It may even be said that the very object of the exact sciences is to spare us these direct verifications.

This procedure is the demonstration by recurrence.
— Ch. I. (1905) Tr. George Bruce Halstead
Henri Poincaré
said
We can not... escape the conclusion that the rule of reasoning by recurrence is irreducible to the principle of contradiction.
— Ch. I. (1905) Tr. George Bruce Halstead
