Los primeros científicos que experimentaron con la física atómica tuvieron la "suerte" de vivir unos tiempos interesantes. En plena Segunda Guerra Mundial, la ciencia alemana se convirtió en un asunto politico: Heisenberg, Planck, Einstein y Debye, entre muchos otros, tuvieron que definirse. Como cientificos y como personas. Y, para algunos de ellos, la definicion no fue la misma.

¿Quién fue Turing, y cuáles fueron sus logros durante sus 41 años de vida? Hoy es mejor conocido como el genio que descifraba las comunicaciones secretas de los alemanes durante la Segunda Guerra Mundial. Fue tambien el padre de la informatica moderna: cada vez que hacemos clic para abrir un archivo, estamos poniendo en practica sus ideas y visiones.Pero fue tambien un hombre que se preguntaba si a los ordenadores les podrian gustar las fresas con nata, o si serian capaces de componer musica. Un genio introvertido, de curioso aspecto y sentido del humor infantil, que sufrio una humillante condena por ser homosexual y acabo su vida envenenado con arsenico (¿se suicido Alan Turing? ¿Lo asesinaron? El autor tiene sus teorias, y alguna informacion de primera mano, sobre este tema controvertido). Una obra imprescindible para geeks informaticos, interesados en la tecnologia y en la historia de las guerras mundiales.

Alan Turing was an extraordinary man who crammed into his 42 years the careers of mathematician, codebreaker, computer scientist and biologist. He is widely regarded as a war hero grossly mistreated by his unappreciative country, and it has become hard to disentangle the real man from the story. Now Dermot Turing has taken a fresh look at the influences on his uncles life and creativity, and the creation of a legend. He discloses the real character behind the cipher-text, answering questions that help the man emerge from his legacy: how did Alans childhood experiences influence him? How did his creative ideas evolve? Was he really a solitary genius? What was his wartime work after 1942, and what of the Enigma story? What is the truth about the conviction for gross indecency, and did he commit suicide? In Alan Turing Decoded, Dermots vibrant and entertaining approach to the life and work of a true genius makes this a fascinating and authoritative read.

"Was wurde geschehen, wenn ich hinter einem Lichtstrahl hereilen und ihn schlielich einholen wurde?" Diese Frage stellte Albert Einstein als 17jahriger. Einige Jahre spater hatte er diesen Gedankengang vollendet und damit die alten Vorstellungen von der Beschaffenheit von Raum und Zeit - uber 200 Jahre bestehendes Gedankengut - hinfallig gemacht. Physiker, Nobelpreistrager, Atombombe, E=mc, Relativitatstheorie... Das sind Schlagworte, die auch heute noch mit dem Namen "Albert Einstein" verbunden sind. Aber wer wei schon, dass Einstein beinahe Prasident von Israel geworden ware? Wer sprach offene Morddrohungen gegen ihn aus? Welche Schuld trifft ihn wirklich am Bau der Atombombe? Und was ist dran an der Behauptung, dass Einstein ein lausiger Schuler war?
