Books like The Number Devil by Hans Magnus Enzenberger

“Il ne vivait que pour les mathématiques, que par les mathématiques“. Paul Erdös fut un mathématicien si prolifique que l'on a inventé un moyen de classer les hommes de science d'après les publications qu'ils avaient signées, soit avec le maître (nombre d'Erdös 1), soit avec un des cosignataires d'un article avec Erdös (nombre d'Erdös 2), soit avec un cosignataire d'un cosignataire d'Erdös (nombre d'Erdös 3) et ainsi de suite... Sans emploi fixe, ni maison, Erdös sillona le monde à un rythme effréné, à la recherche de nouveaux problèmes et de nouveaux talents mathématiques avec lesquels il pouvait travailler. IL se présentait à l'improviste chez l'un de ses collègues en déclarant : “Mon cerveau est ouvert, je vous écoute, quel théorème voulez-vous prouver ?“. Il voyait dans les mathématiques une recherche de la beauté et de l'ultime vérité, quête qu'il a poursuivie jusqu'à sa mort en 1996, à l'âge de 83 ans. Paul Hoffman retrace ici la vie du chercheur et expose les importants problèmes mathématiques, du Grand théorème de Fermat jusqu'au plus frivole “dilemme de Monty Hall“. Il porte un regard aigü sur le monde des mathématiques et dépeint un inoubliable portrait d'Erdös, scientifique-philosophe, à la fois espiègle et charmant, un des derniers mathématiciens romantiques.

G. H. Hardy was one of this century's finest mathematical thinkers, renowned among his contemporaries as a 'real mathematician … the purest of the pure'. He was also (as C. P. Snow recounts in his Foreword to the 1967 edition) 'unorthodox, eccentric, radical, ready to talk about anything'. This 'apology', written in 1940 as his mathematical powers were declining, offers a brilliant and engaging account of mathematics as very much more than a science; when it was first published, Graham Greene hailed it alongside Henry James's notebooks as 'the best account of what it was like to be a creative artist'. C. P. Snow's Foreword gives sympathetic and witty insights into Hardy's life, with its rich store of anecdotes concerning his collaboration with the brilliant Indian mathematician Ramanujan, his aphorisms and idiosyncrasies, and his passion for cricket. This is a unique account of the fascination of mathematics and of one of its most compelling exponents in modern times.

In The Book of Numbers, two famous mathematicians fascinated by beautiful and intriguing number patterns share their insights and discoveries with each other and with readers. John Conway is the showman, master of mathematical games and flamboyant presentations; Richard Guy is the encyclopedist, always on top of problems waiting to be solved. Together they show us why patterns and properties of numbers have captivated mathematicians and non-mathematicians alike for centuries. The Book of Numbers features Conway and Guy's favorite stories about all the kinds of numbers any of us is likely to encounter, and many others besides. "Our aim," the authors write, "is to bring to the inquisitive reader...an explanation of the many ways the word 'number' is used." They explore patterns that emerge in arithmetic, algebra, and geometry, describe these patterns' relevance both inside and outside mathematics, and introduce the strange worlds of complex, transcendental, and surreal numbers. This unique book brings together facts, pictures and stories about numbers in a way that no one but an extraordinarily talented pair of mathematicians and writers could do.
