Henri Poincaré

  • Henri Poincaré

    Henri was born on April 29, 1854. Henri contributed to many subjects during his lifetime. He is referred to as the "last polymath" because of his contributions to math and the sciences. Henri had many discoveries in the philosophy of mathematics and science. Henri Poincaré passed away on July 17, 1912.
  • Lycée Henri Poincaré

    Poincaré spent eleven years at the Lycée. While he was there, he proved to be one of the top students, not in just one class, but in every class. Poincaré was deemed the "monster of mathematics" by his teachers. He then went on to win prizes in the Concours Général, which was a competition against top students from all across France. His time there was so exceptional that the Lycée was named Lycée Henri Poincaré.
  • Poincaré Algebraic Coordinates

    In a paper, Poincaré stated that linear differential equations with algebraic coefficients could be solved. He also discovered that points on an algebraic curve can be expressed as Fuchsian functions of an auxiliary variable (Gray, Jeremy, and Edward G. Gray, p. 232). Poincaré also discovered the uniformization theorem. However, this was just the beginning of these formulas. The formulas would not be fully completed until approximately twenty-six years later.
  • Poincaré's First Public Recognition

    In 1890, Poincaré won a distinguished prize for his study of the motion of planets and the solar system. It covered the 3 body problem in celestial mechanics. During this time, he also wrote two other major works on celestial mechanics (Gray, Jeremy, and Edward G. Gray, p. 4). Poincaré was able to give the first mathematical illustration of chaotic motion, was the first to make important use of the idea of invariant integrals and gave the first account of homoclinic points.
  • Poincaré's volumes: "Les Méthodes nouvelles de la mécanique céleste"

    Henry Poincaré published three volumes of "Les Méthodes nouvelles de la mécanique céleste". He published these between the years 1892 and 1899. This led to the three-body problem approach. This is said to be the beginning of the chaos theory.

    Henri Poincaré passed away on July 17, 1912.
