Book Description
Tout comme monsieur Jourdain faisait de la prose sans le savoir, nous faisons des maths sans nous en rendre compte. Car les maths sont partout. Quand vous lancez trois dés en l'air, quelle est la probabilité qu'ils retombent tous du même côté ? Quelle est la couleur qui a le plus de chances de sortir à la table du casino ? Entre deux jeux d'argent apparemment identiques quel est celui qui pourrait vous faire gagner le plus d'argent ? Ce livre nous met au défi de résoudre 21 énigmes - de difficulté croissante au fil des pages - afin, disent les auteurs, de « faire des maths avec peu de chiffres et beaucoup d'idées ». Subterfuges, mensonges, chausse-trapes, duperies, viennent à la rescousse d'une variété infinie de raisonnements mathématiques pour tenter de résoudre des énigmes dont la simplicité n'est qu'apparente... 21 énigmes pour comprendre (enfin !) les maths est un livre drôle et intelligent qui fait appel à la logique, au raisonnement, à la déduction, et la part belle à la philosophie dont les auteurs aiment à montrer les liens étroits qu'elle entretient avec les mathématiques. Thierry Maugenest est l'auteur d'une vingtaine de livres dont Les Rillettes de Proust et autres fantaisies littéraires. Antoine Houlou-Garcia est docteur en sciences sociales, fondateur de la chaîne YouTube Arithm'Antique, lauréat du prix Tangente de la vulgarisation scientifique ; il est l'auteur de La Politique, manuel à l'usage de ceux qui n'y comprennent plus rien et, avec Thierry Maugenest, du Théorème d'hypocrite, histoire de la manipulation par les chiffres, publiés aux Editions Albin Michel.

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
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.

Book Description
Semidefinite and conic optimization is a major and thriving research area within the optimization community. Although semidefinite optimization has been studied (under different names) since at least the 1940s, its importance grew immensely during the 1990s after polynomial-time interior-point methods for linear optimization were extended to solve semidefinite optimization problems. Since the beginning of the 21st century, not only has research into semidefinite and conic optimization continued unabated, but also a fruitful interaction has developed with algebraic geometry through the close connections between semidefinite matrices and polynomial optimization. This has brought about important new results and led to an even higher level of research activity. This Handbook on Semidefinite, Conic and Polynomial Optimization provides the reader with a snapshot of the state-of-the-art in the growing and mutually enriching areas of semidefinite optimization, conic optimization, and polynomial optimization. It contains a compendium of the recent research activity that has taken place in these thrilling areas, and will appeal to doctoral students, young graduates, and experienced researchers alike. The Handbook’s thirty-one chapters are organized into four parts: Theory, covering significant theoretical developments as well as the interactions between conic optimization and polynomial optimization; Algorithms, documenting the directions of current algorithmic development; Software, providing an overview of the state-of-the-art; Applications, dealing with the application areas where semidefinite and conic optimization has made a significant impact in recent years.

Book Description
The essays in this edited volume, written in English and French, tackle the intriguing problems of fear and safety by analysing their various meanings and manifestations in literature and other narrative media. The articles bring forth new, cross-cultural interpretations on fear and safety through examining what kinds of genre-specific means of world-making narratives use to express these two affectivities. The articles also show how important it is to study these themes in order to understand challenges in times of global threats, such as the climate crisis, and - to imagine a better future. The main themes of the book are approached from various theoretical perspectives as related to their literary and cultural representations. Recent trends in research, such as affect and risk theory, serve as the basis for the discussion. Many of the articles in the volume discuss apocalyptic and dystopian narratives that currently permeate the entire cultural landscape. Dystopian narratives do not only deal with future threats, such as totalitarianism, technocracy, or environmental disasters, but also suggest alternative ways of being and new hopes in the form of political resistance. The articles in the volume also draw from disciplines such as gender studies and trauma studies to examine the threats posed by collective fears and aggression on individuals' lives and propose ways of coping with fear. These themes are addressed also in articles analysing new adaptations of old myths that retell stories of the past.

Book Description
From acclaimed economists George Akerlof and Robert Shiller, the case for why government is needed to restore confidence in the economy The global financial crisis has made it painfully clear that powerful psychological forces are imperiling the wealth of nations today. From blind faith in ever-rising housing prices to plummeting confidence in capital markets, "animal spirits" are driving financial events worldwide. In this book, acclaimed economists George Akerlof and Robert Shiller challenge the economic wisdom that got us into this mess, and put forward a bold new vision that will transform economics and restore prosperity. Akerlof and Shiller reassert the necessity of an active government role in economic policymaking by recovering the idea of animal spirits, a term John Maynard Keynes used to describe the gloom and despondence that led to the Great Depression and the changing psychology that accompanied recovery. Like Keynes, Akerlof and Shiller know that managing these animal spirits requires the steady hand of government—simply allowing markets to work won't do it. In rebuilding the case for a more robust, behaviorally informed Keynesianism, they detail the most pervasive effects of animal spirits in contemporary economic life—such as confidence, fear, bad faith, corruption, a concern for fairness, and the stories we tell ourselves about our economic fortunes—and show how Reaganomics, Thatcherism, and the rational expectations revolution failed to account for them. Animal Spirits offers a road map for reversing the financial misfortunes besetting us today. Read it and learn how leaders can channel animal spirits—the powerful forces of human psychology that are afoot in the world economy today. In a new preface, they describe why our economic troubles may linger for some time—unless we are prepared to take further, decisive action.

Book Description
This book is the fruit of a symposium in honor of Ted Eisenberg concerning the growing divide between the mathematics community and the mathematics education community, a divide that is clearly unhealthy for both. The work confronts this disturbing gap by considering the nature of the relationship between mathematics education and mathematics, and by examining areas of commonality as well as disagreement. It seeks to provide insight into the mutual benefit both stand to gain by building bridges based on the natural bonds between them.

Book Description
'NDiaye is a hypnotic storyteller with an unflinching understanding of the rock-bottom reality of most people's life.' New York Times ' One of France's most exciting prose stylists.' The Guardian. Obsessed by her encounters with the mysterious green women, and haunted by the Garonne River, a nameless narrator seeks them out in La Roele, Paris, Marseille, and Ouagadougou. Each encounter reveals different aspects of the women; real or imagined, dead or alive, seductive or suicidal, driving the narrator deeper into her obsession, in this unsettling exploration of identity, memory and paranoia. Self Portrait in Green is the multi-prize winning, Marie NDiaye's brilliant subversion of the memoir. Written in diary entries, with lyrical prose and dreamlike imagery, we start with and return to the river, which mirrors the narrative by posing more questions than it answers.
