"Jules Henri Poincaré (UK: /ˈpwæ̃kɑːreɪ/ [US: stress final syllable], French: [ɑ̃ʁi pwɛ̃kaʁe] (listen); 29 April 1854 – 17 July 1912) was a French mathematician, theoretical physicist, engineer, and philosopher of science. He is often described as a polymath, and in mathematics as "The Last Universalist", since he excelled in all fields of the discipline as it existed during his lifetime.
As a mathematician and physicist, he made many original fundamental contributions to pure and applied mathematics, mathematical physics, and celestial mechanics. In his research on the three-body problem, Poincaré became the first person to discover a chaotic deterministic system which laid the foundations of modern chaos theory. He is also considered to be one of the founders of the field of topology." - (en.wikipedia.org 18.04.2022)
