Gisèle Gelbert
The Illiterate Brain
Is illiteracy a social scourge, or is it an aphasia-like disorder? To find the answer, Gisèle Gelbert delves into the mysteries of the brain of an illiterate person, and teaches us the art of `repairing' it. By thoroughly breaking down each linguistic act, she is able to define and localise with great accuracy the disorders observed in both written and oral expression. She also makes use of the schema to develop exercices that are especially adapted to the clinical observation of localised disorders, thus opening the door to new therapeutic possiblilities. Gisèle Gelbert is a neurologist and aphasiologist. She is the author of "Lire c'est vivre "(Opus, 1996) and "Lire c'est aussi écrire" (1998).
Pierre Lévy
Cyberculture
What is cyberculture? What are the social and cultural implications behind this technical phenomenon? Could it be held responsible for altering our relationship to knowledge? These are some of the questions addressed in Cyberculture, which covers such aspects of new technology as numerisation, navigation, memory, programming, software, virtual reality, multimedia, interactivity, and electronic mail. Written for the non-power user, this is a clear, complete and highly accessible presentation of new technologies, their uses and future stakes. Pierre Lévy is a philosopher who teaches at the University of Paris-VIII, in the hypermedia department.
Gilles Godefroy
The Adventure of Numbers
Numbers never cease to fascinate. The Adventure of Numbers recounts the history of the gradual discovery of numerical characteristics, from the early days of arithmetic to the most sophisticated recent issues: Could a robot be created that would reduce all mathematics to simple sums? Are we sure that arithmetic does not conceal contradictions? Can all mathematical truths be demonstrated? The surprising answers given by Gilles Godefroy are the latest in an on-going saga that will doubtless continue to astound us. Mathematician Gilles Godefroy is a research director at the French Centre National de la recherche scientifique (CNRS).
