Poincaré graduated from the University of Paris in 1879. Henri pointcarre free#He realised that they could be used to model the behaviour of multiple bodies in free motion within the solar system. He not only faced the question of determining the integral of such equations, but also was the first person to study their general geometric properties. Poincaré devised a new way of studying the properties of these equations. His doctoral thesis was in the field of differential equations. He carried out the official investigation into the accident in a characteristically thorough and humane way.Īt the same time, Poincaré was preparing for his doctorate in sciences in mathematics under the supervision of Charles Hermite. He was on the scene of a mining disaster at Magny in August 1879 in which 18 miners died. He went on to study at the École des Mines, continuing to study mathematics in addition to the mining engineering syllabus and received the degree of ordinary engineer in March 1879.Īs a graduate of the École des Mines he joined the Corps des Mines as an inspector for the Vesoul region in northeast France. There he studied mathematics as a student of Charles Hermite, continuing to excel and publishing his first paper ( Démonstration nouvelle des propriétés de l'indicatrice d'une surface) in 1874. Poincaré entered the École Polytechnique in 1873. He graduated from the Lycée in 1871 with a Bachelor's degree in letters and sciences.ĭuring the Franco-Prussian War of 1870 he served alongside his father in the Ambulance Corps. However, poor eyesight and a tendency towards absentmindedness may explain these difficulties (Carl, 1968). (His poorest subjects were music and physical education, where he was described as "average at best" (O'Connor et al., 2002). His mathematics teacher described him as a "monster of mathematics" and he won first prizes in the concours général, a competition between the top pupils from all the Lycées across France. He spent eleven years at the Lycée and during this time he proved to be one of the top students in every topic he studied. In 1862 Henri entered the Lycée in Nancy (now renamed the Lycée Henri Poincaré in his honour, along with the University of Nancy). Educationĭuring his childhood he was seriously ill for a time with diphtheria and received special instruction from his gifted mother, Eugénie Launois (1830-1897). Another notable member of Jules' family was his cousin, Raymond, who would become the President of France, 1913 to 1920, and a fellow member of the Académie française. His adored younger sister Aline married the spiritual philosopher Emile Boutroux. His father Leon Poincaré (1828-1892) was a professor of medicine at the University of Nancy (Sagaret, 1911). Poincaré was born on Apin Cité Ducale neighborhood, Nancy, France into an influential family (Belliver, 1956). The Poincaré group used in physics and mathematics was named after him. Thus he obtained perfect invariance of all of Maxwell's equations, the final step in the formulation of the theory of special relativity. Poincaré discovered the remaining relativistic velocity transformations and recorded them in a letter to Lorentz in 1905. Poincaré introduced the modern principle of relativity and was the first to present the Lorentz transformations in their modern symmetrical form. He is considered to be one of the founders of the field of topology. 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 was responsible for formulating the Poincaré conjecture, one of the most famous problems in mathematics. Poincaré 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.Īs a mathematician and physicist, he made many original fundamental contributions to pure and applied mathematics, mathematical physics, and celestial mechanics. Jules Henri Poincaré (Ap– July 17, 1912) ( IPA: ) was one of France's greatest mathematicians and theoretical physicists, and a philosopher of science.
