Mathematics and the Unexpected by Ivar Ekeland (English) Paperback Book

Description: Mathematics and the Unexpected by Ivar Ekeland In this brief treatise, Ekelund explains some philosophical implications of recent mathematics. He examines randomness, the geometry involved in making predictions, and why general trends are easy to project, but particulars are practically impossible. FORMAT Paperback LANGUAGE English CONDITION Brand New Publisher Description "Not the least unexpected thing about Mathematics and the Unexpected is that a real mathematician should write not just a literate work, but a literary one."—Ian Stewart, New Scientist"In this brief, elegant treatise, assessable to anyone who likes to think, Ivar Ekelund explains some philosophical implications of recent mathematics. He examines randomness, the geometry involved in making predictions, and why general trends are easy to project (it will snow in January) but particulars are practically impossible (it will snow from 2 p.m. to 5 p.m. on the 21st)."—Village Voice Author Biography Ivar Ekeland is president of Université Paris--Dauphine and founder of the Centre de Récherche de mathématiques de la décision. He is the author of several books on mathematics. Table of Contents Foreword by Felix E. Browder Introduction 1.

The Shattered Crystal The Impossible Calculations Poincar Kirkus US Review Mathematicians have always stressed elegance and economy in formulating proofs. Ekeland fulfills both these criteria in this exposition of themes drawn from contemporary mathematics - even providing anidiomatic English translation from his own French original. His purpose is to describe how mathematicians have dealt with time; in so doing, he draws upon the celebrated 19th-century mathematician Henri Poincare, and several contemporaries: Rene Thom of catastrophe theory fame, and others associated with the dynamics of chaos. As background, Ekeland describes the historic attempts to predict the positions of the planets, which culminated in Keplers laws of planetary motion. Later, Newton was able to derive the laws from his own development of the law of universal gravitation and calculus. In Keplers and Newtons formulations, time can be read forward and backward: the laws are symmetric with respect to time; the universe is a deterministic clockwork. By the 19th century, however, it was clear that the values derived from Keplers laws were only crude approximations. It took Poincare to show that even with the better and better approximations, certain orbits could not be computed. Thus, determinism was gone. In its wake contemporary mathematicians have seen that "initial conditions" can lead to extraordinary future states - the repeated "patterns" of chaos, for example, and curves with "strange attractors" and self-replicating geometries. In other instances, the conditions that define "dissipative structures" can lead to values that give rise to the "cusps" of catastrophe theory. Ekeland believes catastrophe theory to be important but limited, unwisely generalized by social and behavioral sciences, in both these mathematical developments, time loses its eternal character and becomes a one-way street - time gains an arrowhead. To conclude these heady observations, Ekeland contrasts the concept of time in the Iliad with the Odyssey, compares Thorns uses of time with Proust, and discourses on evolution, Stephen Jay Gould, and Hieronymous Bosch. For readers of philosophical and mathematical bent, an elequent expression of new ideas.
