Discusses species of dinosaurs found on the continent of North America 70 million years ago.

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.

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.

Reknowned undercover agent in World War II is promised his freedom if he reenter's Nazi-occupied Paris to steal Germany's greatest wartime secret.

The complete story of how the German Enigma codes were broken. Perfect for fans of THE IMITATION GAME, the new film on Alan Turing's Enigma code, starring Benedict Cumberbatch. Breaking the German Enigma codes was not only about brilliant mathematicians and professors at Bletchley Park. There is another aspect of the story which it is only now possible to tell. It takes in the exploits of spies, naval officers and ordinary British seamen who risked, and in some cases lost, their lives snatching the vital Enigma codebooks from under the noses of Nazi officials and from sinking German ships and submarines. This book tells the whole Enigma story: its original invention and use by German forces and how it was the Poles who first cracked - and passed on to the British - the key to the German airforce Enigma. The more complicated German Navy Enigma appeared to them to be unbreakable.
