PlanetMath: Poincaré, Jules Henri Henri Poincaré and Albert Einstein had an interesting relationship concerning their work on relativity (one might actually describe it as a lack of a relationship). Poincaré's first area of interest in mathematics was the Fuchsian function that he named after the mathematician Lazarus Fuch because Fuch was known for being a good teacher and done alot of research in differential equations and in the theory of functions. Poincaré had the opposite philosophical views of Bertrand Rusell and Gottlob Fredge who believed that mathematics were a branch of logic. planetmath.org /encyclopedia/JulesHenriPoincare.html

HENRI POINCARE Although Henri Poincaré (1854-1912) died before the outbreak of the First World War, he founded subjects of intense interest to present-day mathematicians. Poincaré's essay won the prize in 1889, even though he only partially solved the problem; what Poincaré found was that (to use modern terminology) mathematical chaos was lurking in Newton's equations for three or more bodies. Poincaré was a pioneer in hyperbolic geometry, which in the 1970's and 1980's became important in the study of 3-manifolds. www.usna.edu /Users/math/meh/poincare.html

Two Philosophical Mistakes in Poincaré Jules Henri Poincaré (1854-1912) was one of the greatest mathematicians of his era and is sometimes said to deserve co-credit with Einstein for the discovery of Relativity. Poincaré's conventionalism is a mistake, but here I am more interested in two other citations and the kind of philosophical mistakes that they demonstrate. For if the premises of a syllogism, he [Poincaré] argues, are in the indicative mood, the conclusion must also be in the indicative, and thus cannot have the form of an imperative; yet to be part of ethics, it would have to take this form. www.friesian.com /poincare.htm

Poincare Henri was described by his mathematics teacher 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. Poincaré was absolutely correct, however, in his criticism of those like Russell who wished to axiomatise mathematics were doomed to failure. Poincaré was a scientist preoccupied by many aspects of mathematics, physics and philosophy, and he is often described as the last universalist in mathematics. www-groups.dcs.st-and.ac.uk /~history/Mathematicians/Poincare.html   (514 words)

Poincaré, Jules Henri on Encyclopedia.com POINCARÉ, JULES HENRI [Poincaré, Jules Henri], 1854-1912, French mathematician, physicist, and author. One of the greatest mathematicians of his age, Poincaré, by research in the theory of functions, especially the automorphic, Fuchsian, and Abelian functions, enlarged the field of mathematical physics. Poincaré not only made important contributions across the full range of mathematics, both pure and applied, but also wrote extensively on the philosophy of science. www.encyclopedia.com /html/P/PoincarJ1.asp   (217 words)

Pierre Curie / By Marie Curie At this moment the Chair of Physics in the physics, chemistry and natural history course at the Sorbonne, obligatory for students of medicine, and familiarly known as P.C.N., was vacant; he applied, and was appointed, due to the influence of Henri Poincaré, who was anxious to free him from the necessity of quitting France. Henri Becquerel assured himself that these properties do not depend on a preliminary isolation, and that they persist when the uranium compound is kept in darkness during several months. He was united in friendship with Henri Brisson and the men of his group. etext.lib.virginia.edu /etcbin/toccer-new2?id=CurPier.sgm&images=images/modeng&data=/texts/english/modeng/parsed&tag=public&part=all   (20791 words)

Disk and Upper Half-Plane Models of Hyperbolic Geomtry To develop the Poincaré disk model, consider a fixed circle, C, in a Euclidean plane. We assume, without loss of generality, that the radius of C is 1, and that its center is at the origin of the Euclidean plane. If we can prove that the relations that exist among these "points", "lines", "distance" and "angles" satisfy all the axioms of the hyperbolic plane, then we have a model of the hyperbolic plane. www.cs.unm.edu /~joel/NonEuclid/model.html   (1249 words)
