Book Description
Toutes les semaines depuis plusieurs années, Elisabeth Busser et Gilles Cohen proposent un jeu mathématique dans " Le Monde " daté du mardi, pour la plus grande joie des dizaines de milliers d'amateurs qui l'attendent avec impatience. Ils ont d'ailleurs reçu, pour ce rendez-vous hebdomadaire, le " Prix d'Alembert " de la Société Mathématique de France. Les 100 premiers jeux, correspondant aux deux premières années de parution, ont été rassemblés dans un premier volume sous le titre " Affaire de Logique ". Voici maintenant les 100 jeux suivants (numéros 101 à 200). Ils sont enrichis des contributions des centaines de lecteurs qui ont écrit pour proposer une autre solution, un développement, une nouvelle question. Accessibles à tous, ne demandant aucune connaissance spécifique mais simplement de l'astuce et de la logique, les problèmes de ce livre donnent parfois lieu à une généralisation passionnante qui fait l'objet d'une deuxième question. C'est pourquoi ils intéresseront autant les collégiens et lycéens que leurs aînés.

Book Description
En 2000, le Clay Institute annonça l'ouverture d'une compétition historique : quiconque résoudra l'un des sept problèmes mathématiques non encore résolus à ce jour et jugés comme les plus difficiles et les plus importants du siècle gagnera un million de dollars ! Cent ans plus tôt, le mathématicien David Hilbert avait déjà proposé un ensemble de vingt-trois problèmes qui occupèrent largement les mathématiciens du XXe siècle. Les problèmes du troisième millénaire - choisis par un comité international de mathématiciens reconnus - sont de même stature et leurs solutions (ou leur absence de solution) joueront un rôle déterminant non seulement en mathématiques, mais pour les sciences en général. Dans ce livre à la fois fascinant et accessible à tout lecteur qui peut se rappeler un peu des mathématiques apprises au lycée, Keith Devlin présente avec beaucoup de clarté ces " Everest " des mathématiques contemporaines qu'il reste à grimper !

Book Description
"Your Mindful Compass" takes us behind the emotional curtain to see the mechanisms regulating individuals in social systems. There is great comfort and wisdom in knowing we can increase our awareness to manage the swift and ancient mechanisms of social control. We can gain greater flexibility by seeing how social controls work in systems from ants to humans. To be less controlled by others, we learn how emotional systems influence our relationship-oriented brain. People want to know what goes on in families that give rise to amazing leaders and/or terrorists. For the first time in history we can understand the systems in which we live. The social sciences have been accumulating knowledge since the early fifties as to how we are regulated by others. S. Milgram, S. Ashe, P. Zimbardo and J. Calhoun, detail the vulnerability to being duped and deceived and the difficulty of cooperating when values differ. Murray Bowen, M.D., the first researcher to observe several live-in families, for up to three years, at the National Institute of Mental Health. Describing how family members overly influence one another and distribute stress unevenly, Bowen described both how symptoms and family leaders emerge in highly stressed families. Our brain is not organized to automatically perceive that each family has an emotional system, fine-tuned by evolution and "valuing" its survival as a whole, as much as the survival of any individual. It is easier to see this emotional system function in ants or mice but not in humans. The emotional system is organized to snooker us humans: encouraging us to take sides, run away from others, to pressure others, to get sick, to blame others, and to have great difficulty in seeing our part in problems. It is hard to see that we become anxious, stressed out and even that we are difficult to deal with. But "thinking systems" can open the doors of perception, allowing us to experience the world in a different way. This book offers both coaching ideas and stories from leaders as to strategies to break out from social control by de-triangling, using paradoxes, reversals and other types of interruptions of highly linked emotional processes. Time is needed to think clearly about the automatic nature of the two against one triangle. Time and experience is required as we learn strategies to put two people together and get self outside the control of the system. In addition, it takes time to clarify and define one's principles, to know what "I" will or will not do and to be able to take a stand with others with whom we are very involved. The good news is that systems' thinking is possible for anyone. It is always possible for an individual to understand feelings and to integrate them with their more rational brains. In so doing, an individual increases his or her ability to communicate despite misunderstandings or even rejection from important others. The effort involved in creating your Mindful Compass enables us to perceive the relationship system without experiencing it's threats. The four points on the Mindful Compass are: 1) Action for Self, 2) Resistance to Forward Progress, 3) Knowledge of Social Systems and the 4) The Ability to Stand Alone. Each gives us a view of the process one enters when making an effort to define a self and build an emotional backbone. It is not easy to find our way through the social jungle. The ability to know emotional systems well enough to take a position for self and to become more differentiated is part of the natural way humans cope with pressure. Now people can use available knowledge to build an emotional backbone, by thoughtfully altering their part in the relationship system. No one knows how far one can go by making an effort to be more of a self-defined individual in relationships to others. Through increasing emotional maturity, we can find greater individual freedom at the same time that we increase our ability to cooperate and to be close to others.

Book Description
This new, third volume of Cohen-Tannoudji's groundbreaking textbook covers advanced topics of quantum mechanics such as uncorrelated and correlated identical particles, the quantum theory of the electromagnetic field, absorption, emission and scattering of photons by atoms, and quantum entanglement. Written in a didactically unrivalled manner, the textbook explains the fundamental concepts in seven chapters which are elaborated in accompanying complements that provide more detailed discussions, examples and applications. * Completing the success story: the third and final volume of the quantum mechanics textbook written by 1997 Nobel laureate Claude Cohen-Tannoudji and his colleagues Bernard Diu and Franck Laloë * As easily comprehensible as possible: all steps of the physical background and its mathematical representation are spelled out explicitly * Comprehensive: in addition to the fundamentals themselves, the books comes with a wealth of elaborately explained examples and applications Claude Cohen-Tannoudji was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris where he also studied and received his PhD in 1962. In 1973 he became Professor of atomic and molecular physics at the Collège des France. His main research interests were optical pumping, quantum optics and atom-photon interactions. In 1997, Claude Cohen-Tannoudji, together with Steven Chu and William D. Phillips, was awarded the Nobel Prize in Physics for his research on laser cooling and trapping of neutral atoms. Bernard Diu was Professor at the Denis Diderot University (Paris VII). He was engaged in research at the Laboratory of Theoretical Physics and High Energy where his focus was on strong interactions physics and statistical mechanics. Franck Laloë was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris. His first assignment was with the University of Paris VI before he was appointed to the CNRS, the French National Research Center. His research was focused on optical pumping, statistical mechanics of quantum gases, musical acoustics and the foundations of quantum mechanics.

Book Description
The idea for Philosophy in a Time of Terror was born hours after the attacks on 9/11 and was realized just weeks later when Giovanna Borradori sat down with Jürgen Habermas and Jacques Derrida in New York City, in separate interviews, to evaluate the significance of the most destructive terrorist act ever perpetrated. This book marks an unprecedented encounter between two of the most influential thinkers of our age as here, for the first time, Habermas and Derrida overcome their mutual antagonism and agree to appear side by side. As the two philosophers disassemble and reassemble what we think we know about terrorism, they break from the familiar social and political rhetoric increasingly polarized between good and evil. In this process, we watch two of the greatest intellects of the century at work.
