Whakarāpopototia te tuhinga:  He pukapuka ā-ringa kei roto ngā tuhipānui me ngā tātaitanga i mahia e Alan Turing i a ia e mahi ana ki te wetewete i a Enigma kua hokona ki te mākete mō te £700,000. Ko te tuhinga 56-whārangi, e whakapono ana koinei anake te tuhinga Turing nui e noho ana, i tuhia i te 1942 i te Kaupapa Kawanatanga me te Kura Cypher i Bletchley Park, i Buckinghamshire. Ko te pukamahi, e whakaatu ana i tana mahi mo nga turanga o te tohu pāngarau me te pūtaiao rorohiko, i hokona mo te $ 1,025,000 (£ 698,000) i roto i te Fine Books & Manuscripts Sale i Bonhams i New York i te Mane. Panuku ki raro mō te ataata. I tuhia e Turing (matau) ngā tuhipoka i te tari matua o te waehere-whakakorenga o Bletchley Park i te tau 1942, ā, i whakatūria e rātau te huarahi mō te pūtaiao rorohiko. E whakapono ana ko nga tuhipoka ko te tuhinga Turing nui anake (matau) e mohiotia ana, e ai ki te kaihokohoko. He pukapuka tuhituhi ā-ringa i roto i te mea e whakaae ana a Alan Turing, te tohunga o te mīhini Enigma o Ingarangi, e pōhēhē ana ia ki tētahi whārite, ka taea te tiki atu ki te $1 miriona (£690,000). I runga ake nei, i tuhituhi ia ko te tohu Leibniz he 'he tino uaua' He tino rongonui a Turing mo tana takoha ki te pakaru i te waehere i whakamahia e nga Tiamana i roto i a raatau miihini Enigma i te Pakanga Tuarua o te Ao i a ia e mahi ana i Bletchley Park, i Buckinghamshire. He maha nga wa e kiia ana ko ia te papa o te rorohiko hou me te mohio mohio. Ko Benedict Cumberbatch, nāna i tākaro a Turing i roto i te Oscar-nominated The Imitation Game, i mea: 'He toa whawhai a Alan Turing, nāna i pakaru te waehere Enigma i āwhina ki te whakamutu i te Pakanga Tuarua o te Ao, te papa o te pūtaiao rorohiko o nāianei, me tētahi tohu o te tangata tāne i noho i te wā o te manawanui, ā, i whakamomori i te mutunga. 'He nui rawa te pānga o tana mahi ki ō tātou oranga o ia rā, ā, ko te whakaaro ki te pupuri i tētahi tuhinga ā-ringa i a ia, he mea whakamiharo.' Ko te pukapuka i roto i nga pepa i waiho e ia i roto i tana hiahia ki tana hoa me tana hoa kaitarau a Robin Gandy. Ko Benedict Cumberbatch, nāna i tākaro a Turing i roto i te whakaingoa Oscar The Imitation Game (māui), i mea: 'Ko te whakaaro ki te pupuri i tētahi tuhinga ā-ringa i a ia he mea whakamiharo' Ko ngā whārangi o ngā tuhipoka e whakaatu ana i ngā mahi ā-roto o...
