Henri Poincaré (1854-1912) was not just one of the most inventive, versatile, and productive mathematicians of all time--he was also a leading physicist who almost won a Nobel Prize for physics and a prominent philosopher of science whose fresh and surprising essays are still in print a century later. The first in-depth and comprehensive look at his many accomplishments, Henri Poincaré explores all the fields that Poincaré touched, the debates sparked by his original investigations, and how his discoveries still contribute to society today.

Math historian Jeremy Gray shows that Poincaré's influence was wide-ranging and permanent. His novel interpretation of non-Euclidean geometry challenged contemporary ideas about space, stirred heated discussion, and led to flourishing research. His work in topology began the modern study of the subject, recently highlighted by the successful resolution of the famous Poincaré conjecture. And Poincaré's reformulation of celestial mechanics and discovery of chaotic motion started the modern theory of dynamical systems. In physics, his insights on the Lorentz group preceded Einstein's, and he was the first to indicate that space and time might be fundamentally atomic. Poincaré the public intellectual did not shy away from scientific controversy, and he defended mathematics against the attacks of logicians such as Bertrand Russell, opposed the views of Catholic apologists, and served as an expert witness in probability for the notorious Dreyfus case that polarized France.

Richly informed by letters and documents, Henri Poincaré demonstrates how one man's work revolutionized math, science, and the greater world.

Le Score:

Vous aurez remarqué que la fiche de chaque livre contient un nombre baptisé SCORE.

De quoi s'agit-il?

Il s'agit d'une évaluation communautaire de chaque livre calculée sur une échelle de 0 à 100.

Cette évaluation repose sur une agrégation de diverses quantités qui reflètent la vie de chaque livre au sein de la communauté ScholarVox. Cette vie s'exprime en fréquence de lecture, nombre d'étagères publiques, privées, professorales dans lesquelles le livre est présent.

Un calcul "propriétaire" mélangeant ces quantités vous restitue sous la forme synthétique d'un Score l'intelligence collective incorporée dans chaque livre. Ce Score n'est pas une note scolaire, c'est bien plus un indicateur de l'aura collective du livre.

Car, pour paraphraser Robert Parker, expert ès-notation des vins, " ...there can never be any substitute for your own reading palate nor any better education than reading the book yourself."
