Collects three of the French mathematician's classic works interpreting the philosophy of science and mathematics.

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...

During his lifetime, Henri Poincare published three major philosophical books which achieved great success: "La science et l'hypothese" (1902), "La valeur de la science" (1905) and "Science et methode" (1908). After his death in 1913, a fourth volume of his philosophical works was published by his heirs as "Dernieres pensees" (1913). The four books constitute the core of Poincare's philosophic works and were given an ovation by scientific and general public. Around 1919, Gustave Le Bon wrote to Poincare's widow. As the director of the "Bibliotheque de Philosophie Scientifique at Flammarion,"...

"Science and Hypothesis" is a study written in 1902, by the French mathematician, Henri Poincare. It was designed with non-specialist readers in mind, and contains information on mathematics, space, physics and biology. The main theme of this work is that the absolute truth of science is non-existent. It postulates that many scientific beliefs are closer to convenient conventions than valid explanations. The chapters of this book include: Number and Magnitude, On the Nature of Mathematical Reasoning, Mathematical Magnitude and Experiment, Space, Non-Euclidean Geometries, Space and Geometry,...

by John Stillwell I. General Reaarb, Poincare's papers on Fuchsian and Kleinian I1'OUps are of Il'eat interest from at least two points of view: history, of course, but also as an inspiration for further mathematical proll'ess. The papers are historic as the climax of the ceometric theory of functions initiated by Riemann, and ideal representatives of the unity between analysis, ceometry, topololY and alcebra which prevailed during the 1880's. The rapid mathematical prOll'ess of the 20th century has been made at the expense of unity and historical perspective, and if mathematics is not to...

This is an EXACT reproduction of a book published before 1923. This IS NOT an OCR'd book with strange characters, introduced typographical errors, and jumbled words. This book may have occasional imperfections such as missing or blurred pages, poor pictures, errant marks, etc. that were either part of the original artifact, or were introduced by the scanning process.

Unter dem Titel Letzte Gedanken sind in dieser Ausgabe verschiedene Abhandlungen und Vorträge vereinigt, die nach eigener Bestimmung des bedeutenden französischen Mathematiker, theoretischen Physiker und Philosophen Henri Poincaré den vierten Band seiner Abhandlungen über Naturphilosophie bilden sollten. Der hochberühmte Mathematiker erwies sich als hervorragender Philosoph, dessen Bücher tiefen E

Das vorliegende Werk beinhaltet sechs Vortrage des bedeutenden franzosischen Mathematiker und Physiker Henri Poincare (1854-1912). Der Verfasser gilt noch heute als einer der herausragendsten Mathematiker des ausgehenden 19. Jahrhunderts. Insgesamt veroffentlichte er um die 250 Werke auf unterschiedlichen Wissenschaftsgebieten. Die bereits genannten sechs Vortrage handeln von der Anwendung der Integralrechnung unter verschiedenen Bedingungen. Sorgfaltig bearbeiteter Nachdruck der Originalausgabe aus dem Jahre 1910.
