A really exciting book about this phase of the war, which will be of interest to any math-oriented hacker, is The Pleasures of Counting by T. W. Körner. http://www.amazon.com/Pleasures-Counting-T-W-K%C3%B6rner/dp/...
Tom Körner 的《The Pleasures of Counting》（ https://www.amazon.com/Pleasures-Counting-T-W-K%C3%B6rner/dp... ）是一本面向大众的应用数学入门书，文笔风趣诙谐，但又极具智力挑战性。（他的个人网站 https://www.dpmms.cam.ac.uk/~twk/……
Tom Körner's "The Pleasures of Counting" ( https://www.amazon.com/Pleasures-Counting-T-W-K%C3%B6rner/dp... ) is an amusingly written yet intellectually challenging introduction to applied maths for the general audience. (His website https://www.dpmms.cam.ac.uk/~twk/…

……至少会发现几处完全超出他们能力范围的地方。Körner 劝大家跳过这些部分，或者更好的做法是找一位愿意讨论这些问题的教授。照这样读下来，Körner 的《The Pleasures of Counting》确实是一件乐事，而且很可能会吸引很多学生投身数学。在我看来，它在很多方面都是自主阅读或大一新生研讨课的理想读物。
…will find at least a few points where they are in over their heads. Körner urges them to skip over such parts or, even better, to find some professor willing to discuss them. Read this way, Körner's The Pleasures of Counting is really a pleasure, and may well attract many students to mathematics. It strikes me, in many ways, as the ideal book for independent reading or for a first-year seminar.
如果你喜欢这类的故事，有一本叫《The Pleasures of Counting》的书里有好几个类似的故事（比如这个、破解恩尼格玛密码、护航船队等）：http://www.amazon.com/Pleasures-Counting-T-W-K%C3%B6rner/dp/... ——它不全是讲二战的，但非常有趣，而且确实包含大量关于战争期间所用数学知识的内容。
If you like stories like this, there are a number of similar stories (e.g. this one, cracking the enigma code, protecting convoys) in a book called The Pleasures of Counting: http://www.amazon.com/Pleasures-Counting-T-W-K%C3%B6rner/dp/... - it's not all world war 2, but is very interesting and does contain a lot of information on the math used during the war.
……适合高中水平的竞赛。如果想找一本有趣（有些地方让人捧腹大笑）、探讨数学在现代生活中的地位以及数学家如何思考数学的书，我推荐 T. W. Körner 的《The Pleasures of Counting》http://www.amazon.com/Pleasures-Counting-T-246-rner/dp/05215... 。无论是阅读难度还是数学门槛，这本都比上面推荐的更具挑战性，但是嘛……
…for high school level contests. For an interesting (in places laugh-out-loud funny) book about the place of mathematics in modern life and how mathematicians think about mathematics, I recommend The Pleasures of Counting by T. W. Körner. http://www.amazon.com/Pleasures-Counting-T-246-rner/dp/05215... This one is more challenging as to reading level and as to mathematical level than the recommendations above, but well…
