Enigma

A NEW YORK TIMES BESTSELLER The official book behind the Academy Award-winning film The Imitation Game, starring Benedict Cumberbatch and Keira Knightley It is only a slight exaggeration to say that the British mathematician Alan Turing (1912-1954) saved the Allies from the Nazis, invented the computer and artificial intelligence, and anticipated gay liberation by decades--all before his suicide at age forty-one. This New York Times–bestselling biography of the founder of computer science, with a new preface by the author that addresses Turing's royal pardon in 2013, is the definitive account of an extraordinary mind and life. Capturing both the inner and outer drama of Turing’s life, Andrew Hodges tells how Turing’s revolutionary idea of 1936--the concept of a universal machine--laid the foundation for the modern computer and how Turing brought the idea to practical realization in 1945 with his electronic design. The book also tells how this work was directly related to Turing’s leading role in breaking the German Enigma ciphers during World War II, a scientific triumph that was critical to Allied victory in the Atlantic. At the same time, this is the tragic account of a man who, despite his wartime service, was eventually arrested, stripped of his security clearance, and forced to undergo a humiliating treatment program--all for trying to live honestly in a society that defined homosexuality as a crime. The inspiration for a major motion picture starring Benedict Cumberbatch and Keira Knightley, Alan Turing: The Enigma is a gripping story of mathematics, computers, cryptography, and homosexual persecution.

Endless Enigma: Eight Centuries of Fantastic Art explores the ways in which artists have sought to explain their world in terms of an alternate reality, drawn from imagination, the subconscious, poetry, nature, myth, and religion. Endless Enigma takes as its point of departure Alfred H. Barr Jr.’s legendary 1936 exhibition at The Museum of Modern Art, New York, Fantastic Art, Dada, Surrealism, which not only introduced these movements to the American public, but also placed them in a historical and cultural context by situating them with artists from earlier centuries. Presenting works from the twelfth century to the present day, this catalogue is organized into six themes—Monsters & Demons, Dreams & Temptation, Fragmented Body, Unconscious Gesture, Super Nature, and Sense of Place. Works included range from medieval gargoyles to twentieth-century works by Louise Bourgeois, Sigmar Polke, and Pablo Picasso as well as contemporary works by Michaël Borremans, Marcel Dzama, and Raymond Pettibon. Masterworks from the likes of Piero di Cosimo, Francisco de Goya, and Titian are considered alongside those by William Blake and Odilon Redon. Time folds and temporal barriers collapse when Damiano Cappelli meets Edvard Munch, and Salvator Rosa encounters Luc Tuymans and Lisa Yuskavage. Salvador Dalí, Sherrie Levine, Giuseppe Arcimboldo, Kerry James Marshall—eight centuries intersect and, as such, this wide-ranging catalogue examines affinities in intention and imagery between works executed across a broad span of time. Organized in collaboration with Nicholas Hall, a specialist in the field of Old Masters and nineteenth-century art, this fully illustrated catalogue is published on the occasion of the eponymous exhibition at David Zwirner, New York, in 2018. It includes new scholarship by Dawn Ades, Olivier Berggruen, and J. Patrice Marandel.

December, 1932 In the bathroom of a Belgian hotel, a French spymaster photographs top-secret documents – the operating instructions of the cipher machine, Enigma. A few weeks later a mathematician in Warsaw begins to decipher the coded communications of the Third Reich and lays the foundations for the code-breaking operation at Bletchley Park. The co-operation between France, Britain and Poland is given the cover-name 'X, Y & Z'. December, 1942 It is the middle of World War Two. The Polish code-breakers have risked their lives to continue their work inside Vichy France, even as an uncertain future faces their homeland. Now they are on the run from the Gestapo. People who know the Enigma secret are not supposed to be in the combat zone, so MI6 devises a plan to exfiltrate them. If it goes wrong, if they are caught, the consequences could be catastrophic for the Allies. Based on original research and newly released documents, X, Y & Z is the exhilarating story of those who risked their lives to protect the greatest secret of World War Two.

Hysteria is probably the condition which best illustrates the tight connection between neurology and psychiatry. While it has been known since antiquity, its renewed studies during the 19th century were mainly due to the work of Jean-Martin Charcot and his school in Paris. This publication focuses on these early developments, in which immediate followers of Charcot, including Babinski, Freud, Janet, Richer, and Gilles de la Tourette were involved. Hysteria is commonly considered as a condition that often leads to spectacular manifestations (e.g. convulsions, palsies), although both structural and functional imaging data confirm the absence of consistent and reproducible structural lesions. While numerous hypotheses have tried to explain the occurrence of this striking phenomenon, the precise nosology and pathophysiology of hysteria remain elusive. This volume offers an enthralling and informative read for neurologists, psychiatrists, and psychologists, as well as for general physicians, historians, and everyone interested in the developments of one of the most intriguing conditions in medicine.
