A fascinating memoir from the man who revitalized visual geometry, and whose ideas about fractals have changed how we look at both the natural world and the financial world.Benoit Mandelbrot, the creator of fractal geometry, has significantly improved our understanding of, among other things, financial variability and erratic physical phenomena. In The Fractalist, Mandelbrot recounts the high points of his life with exuberance and an eloquent fluency, deepening our underst...

A groundbreaking mathematician presents a new model for understanding financial marketsBenoit B. Mandelbrot is world-famous for inventing fractal geometry, making mathematical sense of a fact everybody knows but that geometers from Euclid on down had never assimilated: Clouds are not round, mountains are not cones, coastlines are not smooth. To these insights we can now add another example: Markets are not the safe bet your broker may claim.Mandelbrot, with...

Benoît Mandelbrot, père de la géométrie fractale, était connu pour son exubérance et son indépendance d’esprit. Ses mémoires, publiés ici à titre posthume, sont le témoignage touchant d’un chercheur génial dont la vie ne fut rien de moins qu’un combat. De sa Pologne natale à la France de Vichy, il passe sa jeunesse à fuir le régime nazi et son existence est d’abord un exercice de survie ; au sortir de la guerre, il se distingue au concours de l’École normale supérieure, mais aussi à celui ...

'The book is well-illustrated, earlier chapters with monochrome portraits of Mandelbrot, his family and those who influenced him, and later ones with striking colour pictures not only of the Mandelbrot set and other computer generated fractals, but also of ‘real’ fractals including cloud formations and rural and mountain scenes … This celebration of Mandelbrot’s scientific life is largely based on interviews that the author had with him when making films on his work … A challenge for...

This is a collection of articles, many written by people who worked with Mandelbrot, memorializing the remarkable breadth and depth of his work in science and the arts. Contributors include mathematicians, physicists, biologists, economists, and engineers, as expected; and also artists, musicians, teachers, an historian, an architect, a filmmaker, and a comic. Some articles are quite technical, others entirely descriptive. All include stories about Benoit.Also included are chapters on frac...

Für Benoît Mandelbrot ist Mathematik Poesie: Schönheit und Beschreibung der Welt. Als Junge kommt er, 1924 in Warschau geboren, nach Paris und wird von seinem Onkel in die Mathematik eingeführt. Chaotische Systeme prägen seine Zeit; während des Krieges muss er sich vieles selbst beibringen. Seiner unkonventionellen Denkweise verdankt Mandelbrot die größten Erfolge, aber auch die Rolle des Außenseiters: Nicht an der Universität, sondern bei IBM in den USA fand er genügend Freiheit für seine...

Le diagnostic prénatal s'entend des pratiques médicales, y compris l'échographie obstétricale et fœtale, ayant pour but de détecter in utero chez l'embryon ou le fœtus une affection d'une particulière gravité. La réactualisation des lois de bioéthique a bien montré l'intérêt du législateur et l'importance que la société attache à l'exercice d'une médecine fœtale de qualité. Les potentielles retombées médico-légales de cet exercice à haut risque, la formidable évolution du diagnostic prénat...
