Henri Poincaré

Classic account of basic methodology and psychology of scientific discovery explains how scientists analyze and choose their working facts and explores the nature of experimentation, theory, and the mind. 1914 edition.

Here is Poincaré's famous discussion of creative psychology as it is revealed in the physical sciences. Explaining how such basic concepts as number and magnitude, space and force were developed, the great French mathematician refutes the skeptical position that modern scientific method and its results are wholly factitious. The places of rigorous logic and intuitive leaps are both established by an analysis of contrasting methods of idea-creation in individuals and in modern scientific traditions. The nature of hypothesis and the role of probability are investigated with all of Poincaré's usual fertility of insight.Partial On the nature of mathematical reasoning. Magnitude and experiment. non-Euclidean geometrics, space and geometry, experiment and geometry. classical mechanics, relative and absolute motion, energy and thermodynamics. hypotheses in physics, the theories of modern physics, the calculus of probabilities, optics and electricity, electro-dynamics."Poincaré's was the last man to take practically all mathematics, both pure and applied as his province. Few mathematicians have had the breadth of philosophic vision that Poincaré's had, and none is his superior in the gift of clear exposition." — Men of Mathematics , Eric Temple Bell, Professor of Mathematics, University of Cambridge

More than any other writer of the twentieth century, Henri Poincaré brought the elegant, but often complicated, ideas about science and mathematics to the general reader. A genius who throughout his life solved complex mathematical calculations in his head, and a writer gifted with an inimitable style, Poincaré rose to the challenge of interpreting the philosophy of science to scientists and nonscientists alike. His lucid and welcoming prose made him the Carl Sagan of his time. This volume collects his three most important Science and Hypothesis (1903); The Value of Science (1905); and Science and Method (1908).

Henri Poincaré was a famous mathematician, theoretical physicist, and philosopher. "Think of two consciousnesses, which are like two worlds impenetrable one to the other. By what right do we strive to put them into the same mold, to measure them by the same standard? Is it not as if one strove to measure length with a gram or weight with a meter? And besides, why do we speak of measuring? We know perhaps that some fact is anterior to some other, but not by how much it is anterior. Therefore two (1) Can we transform psychologic time, which is qualitative, into a quantitative time? (2) Can we reduce to one and the same measure facts which transpire in different worlds?..."

"Dernières pensées" de Henri Poincaré. Mathématicien, physicien et philosophe français (1854-1912).

Book by Jules-Henri Poincaré

Apparso postumo, un anno dopo la morte di Poincaré, Ultimi pensieri raccoglie saggi, articoli e testi di conferenze risalenti all’ultimo decennio della sua vita, che compongono una sorta di testamento scientifico e intellettuale del grande studioso francese.Ai temi classici della sua riflessione critica (l’origine e il fondamento della geometria, la relazione tra matematica e logica, il primato dell’intuizione), si affiancano quelli legati alle nuove teorie fisiche (relatività e teoria dei quanti), che Poincaré affronta con straordinaria acutezza, da scienziato e da filosofo. Impreziosiscono la raccolta alcuni scritti etici di grande modernità, sul rapporto tra morale e scienza, e sulla libertà scientifica.La chiarezza espositiva, la forza dell’argomentazione e lo stile al tempo stesso appassionato e rigoroso rendono il libro affascinante ed estremamente attuale. Le sue pagine permettono di cogliere lo spirito scientifico del primo Novecento e di apprezzare l’influenza esercitata da Poincaré sul pensiero contemporaneo.

“ Parmi les hommes qui ont, tous utilement, mais plus ou moins brillamment servi la science, les uns avaient reçu dans leur jeunesse une éducation classique solide, parfois raffinée, tandis que les autres n’avaient eu qu’une formation littéraire hâtive, incomplète et sommaire. On serait tenté d’en conclure que l’étude des lettres est inutile aux savants, puisque beaucoup d’entre eux ont pu s’en passer. Ce serait aller un peu vite en besogne. Est-il certain qu’on ne saurait faire de différence entre les œuvres des uns et des autres et y reconnaître une sorte de marque d’origine. C’est là une comparaison que je ne veux pas faire ici, il faudrait citer des noms propres, et je ne voudrais désobliger personne, même les morts. En pareille matière, les appréciations sont difficiles, mais quand même on aurait démontré que les uns ont été aussi bons savants que les autres, qu’est-ce que cela prouverait ? Le fait s’expliquerait tout naturellement. Il y a eu de longues années où il était difficile de percer sans avoir fait ses classes, et en général de sortir de son rang. Ceux qui y sont parvenus n’ont pu le faire que grâce à une énergie exceptionnelle qui leur tenait lieu de bien d’autres avantages, et qui pouvait les mettre de pair avec des esprits plus cultivés, mais servis par des caractères moins bien trempés...”

The History of Mathematical PhysicsThe Past and the Future of Physics.What is the present state of mathematical physics? What are the problems it is led to set itself? What is its future? Is its orientation about to be modified?Ten years hence will the aim and the methods of this science appear to our immediate successors in the same light as to ourselves; or, on the contrary, are we about to witness a profound transformation? Such are the questions we are forced to raise in entering to-day upon our investigation.If it is easy to propound them: to answer is difficult. If we felt tempted to risk a prediction, we should easily resist this temptation, by thinking of all the stupidities the most eminent savants of a hundred years ago would have uttered, if some one had asked them what the science of the nineteenth century would be. They would have thought themselves bold in their predictions, and after the event, how very timid we should have found them. Do not, therefore, expect of me any prophecy.But if, like all prudent physicians, I shun giving a prognosis, yet I can not dispense with a little diagnostic; well, yes, there are indications of a serious crisis, as if we might expect an approaching transformation. Still, be not too anxious: we are sure the patient will not die of it, and we may even hope that this crisis will be salutary, for the history of the past seems to guarantee us this. This crisis, in fact, is not the first, and to understand it, it is important to recall those which have preceded. Pardon then a brief historical sketch.

Trieste Publishing has a massive catalogue of classic book titles. Our aim is to provide readers with the highest quality reproductions of fiction and non-fiction literature that has stood the test of time. The many thousands of books in our collection have been sourced from libraries and private collections around the world.The titles that Trieste Publishing has chosen to be part of the collection have been scanned to simulate the original. Our readers see the books the same way that their first readers did decades or a hundred or more years ago. Books from that period are often spoiled by imperfections that did not exist in the original. Imperfections could be in the form of blurred text, photographs, or missing pages. It is highly unlikely that this would occur with one of our books. Our extensive quality control ensures that the readers of Trieste Publishing's books will be delighted with their purchase. Our staff has thoroughly reviewed every page of all the books in the collection, repairing, or if necessary, rejecting titles that are not of the highest quality. This process ensures that the reader of one of Trieste Publishing's titles receives a volume that faithfully reproduces the original, and to the maximum degree possible, gives them the experience of owning the original work.We pride ourselves on not only creating a pathway to an extensive reservoir of books of the finest quality, but also providing value to every one of our readers. Generally, Trieste books are purchased singly - on demand, however they may also be purchased in bulk. Readers interested in bulk purchases are invited to contact us directly to enquire about our tailored bulk rates.

Here is an accurate and readable translation of a seminal article by Henri Poincaré that is a classic in the study of dynamical systems popularly called chaos theory. In an effort to understand the stability of orbits in the solar system, Poincaré applied a Hamiltonian formulation to the equations of planetary motion and studied these differential equations in the limited case of three bodies to arrive at properties of the equations’ solutions, such as orbital resonances and horseshoe orbits. Poincaré wrote for professional mathematicians and astronomers interested in celestial mechanics and differential equations. Contemporary historians of math or science and researchers in dynamical systems and planetary motion with an interest in the origin or history of their field will find his work fascinating.

John Stillwell was the recipient of the Chauvenet Prize for Mathematical Exposition in 2005. The papers in this book chronicle Henri Poincaré's journey in algebraic topology between 1892 and 1904, from his discovery of the fundamental group to his formulation of the Poincaré conjecture. For the first time in English translation, one can follow every step (and occasional stumble) along the way, with the help of translator John Stillwell's introduction and editorial comments. Now that the Poincaré conjecture has finally been proved, by Grigory Perelman, it seems timely to collect the papers that form the background to this famous conjecture. Poincaré's papers are in fact the first draft of algebraic topology, introducing its main subject matter (manifolds) and basic concepts (homotopy and homology). All mathematicians interested in topology and its history will enjoy this book. This volume is one of an informal sequence of works within the History of Mathematics series. Volum

Excerpt from La Valeur de la ScienceIl faut ajouter que ceux qui ont peur de l'une, auront peur aussi de l'autre car ce sont ceux qui, en toutes choses, se préoccupent avant tout des conséquences. En un mot, je rapproche les deux vérités, parce que ce sont les mêmes raisons qui nous les font aimer et parce que ce sont les mêmes raisons qui nous les font redouter....

Edited by Daniel Goroff, Harvard University This English-language edition of Poincare's landmark work is of interest not only to historians of science, but also to mathematicians. Beginning from an investigation of the three-body problem of Newtonian mechanics, Poincare lays the foundations of the qualitative solutions of differential equations. To investigate the long-unsolved problem of the stability of the Solar System, Poincare invented a number of new techniques including canonical transformations, asymptotic series expansions, and integral invariants. These "new methods" are even now finding applications in chaos and other contemporary disciplines. Volume Periodic and asymptotic Introduction by Daniel Goroff. Generalities and the Jacobi method. Series integration. Periodic solutions. Characteristic exponents. Nonexistence of uniform integrals. Approximate development of the perturbative function. Asymptotic solutions. Volume Approximations by Formal calculus. Methods of Newcomb and Lindstedt. Application to the study of secular variations. Application to the three-body problem. Application to orbits. Divergence of the Lindstedt series. Direct calculation of the series. Other methods of direct calculation. Gylden methods. Case of linear equations. Bohlin methods. Bohlin series. Extension of the Bohlin method. Volume Integral invariants and asymptotic properties of certain Integral invariants. Formation of invariants. Use of integral invariants.

Ensaios fundamentais, de Henri PoincaréAinda em vida, Henri Poincaré (1854-1912) foi considerado por Bertrand Russell "a maior figura produzida pela França nos tempos modernos". A originalidade de suas ideias e as metodologias que inventou não apenas marcaram profundamente a matemática, a física e a astronomia, mas estão na origem de parte significativa dos atuais desenvolvimentos dessas disciplinas. "Ensaios fundamentais" é uma edição única que não existe em lugar nenhum do mundo. Resulta de um trabalho de pesquisa realizado por dois historiadores da ciência, Antônio Augusto Passos Videira e Ildeu de Castro Moreira, que selecionaram em revistas científicas os artigos de divulgação mais representativos de Poincaré.
