20201207 白金汉郡米尔顿凯恩斯布莱奇公园Bombe破译机 必应壁纸 英国

这些复古转子帮助改变了历史进程。这是一个炸弹机器，由一个团队开发，其中包括在第二次世界大战期间白金汉郡秘密密码破解中心布莱奇公园的计算机科学家艾伦·图灵。它有助于破解“无法破解”的谜码，德国人用它加密战争行动信息。“谜”代码本身就是由一台转子驱动的机器产生的，它每天都会对代码进行重新置乱，因此炸弹会镜像这些机制来跟上不断变化的加密技术。轰炸和其他可编程机器对敌人军事计划的洞察有助于加速盟军的最终胜利。

今天，布莱奇公园拥有国家计算机博物馆。多亏了前瞻性的教育努力，计算机科学不再是一个谜。本周，英国各地的学校都将参加“编码小时”，这是一系列60分钟的编码课程代码.org，一个有有趣主题的简短编码教程的资源。它与美国计算机科学教育周（Computer Science Education Week）有关，这是一项旨在让更多年轻人学习这一重要学科的年度活动。

These retro rotors helped to change the course of history. This is a Bombe machine, developed by a team including pioneering computer scientist Alan Turing at Bletchley Park, the secret code-breaking centre in Buckinghamshire, during World War Two. It was instrumental in cracking the 'uncrackable' Enigma code, which the Germans used for encrypting war operations messages. The Enigma code was itself generated by a rotor-driven machine that re-scrambled the code each day - so the Bombe mirrored those mechanics to keep up with the changing encryption. Insights the Bombe and other programmable machines provided into the enemy’s military plans helped to speed up the Allies' eventual triumph. Today Bletchley Park hosts the National Museum of Computing. And thanks to forward-thinking educational efforts, computer science is no longer such an enigma. Schools across the UK will be taking part in the Hour of Code this week, a series of 60-minute coding sessions offered through Code.org, a resource for short coding tutorials with fun themes. It is linked to Computer Science Education Week in the US, an annual event aimed at getting more youngsters to take up this important subject.
