Currently reading Pi in the Sky which is an awesome book which I would particularly recommend as a very readable, tangent-laden ponder for programmers without a significant background in formal mathematics who like history, mathematics…
我非常怀念 John Barrows 写的《Pi in the Sky》。它更偏重几何和逻辑。而 Jeremy Kun 的《A Programmer's Introduction to Mathematics》覆盖面很广，如果你对编程也感兴趣的话，读这本很合适。……
I remember Pi in the Sky by John Barrows very fondly. It has more of a focus on geometry and logic. A Programmer's Introduction to Mathematics by Jeremy Kun is wide ranging and appropriate if there is also interest in programming.…
他的那本《Pi in the Sky》是我年轻时对我影响最大的两本数学书之一；另一本是 Edna Kramer 的《Modern Mathematics》。我之前还不知道他去世了。感谢发帖分享。
His book Pi in the Sky was one of the two most influential math books for me in my youth; the other was Modern Mathematics by Edna Kramer. I had not heard of his death. Thanks for posting about it.
就在几周前，我收到了一封特别暖心的邮件：> 嗨！这可能显得有点突兀，事实也确实如此，但几年前我在一次图书馆二手书特卖会上买到了《Pi in the Sky》这本书。上面盖着你个人的藏书章，所以我猜是你以前在图书馆义卖买下、后来又捐回去了？在这之前我从没读过任何觉得有意思的数学书，是它让我开始阅读……
Just a few weeks ago I got an absolutely delightful email: > Ні! This might seem a little out of the blue and it is but a few years ago at a library book sale I got the book "Pi in the Sky". It has your personal library stamp on it, so I guess YOU got it at a library sale and then re-donated it? I had never read anything about math before that was at all interesting and it got me reading…
