OP 文章里链接的那篇 Underwood Dudley 关于“三等分角者”的文章，是我最近读到的最有趣的东西之一。我自己也认识几个怪人，我总是觉得他们投入到怪癖上的精力和时间既令人佩服……
The Underwood Dudley article on “trisectors” linked in OP’s article is one of the more delightful things I’ve read in awhile. Being acquainted with a few cranks myself, I always find the energy and time they have to devote to crankery both impressive…
根据楼里其他人的提及，看来 Dudley 最终根据它出了一本书：https://www.amazon.com/Trisectors-Spectrum-Underwood-Dudley/... 以及 https://www.amazon.com/Budget-Trisections-Underwood-Dudley/d...（其书名大概是受到了 De Morgan 的《A Budget of Paradoxes》的启发）。编辑：我觉得第二本……
Per someone else's mention elsewhere in the thread, it looks like Dudley eventually published a book based on it: https://www.amazon.com/Trisectors-Spectrum-Underwood-Dudley/... and also https://www.amazon.com/Budget-Trisections-Underwood-Dudley/d... (whose title was probably inspired by De Morgan's "A Budget of Paradoxes"). Edit: I think the second…
I don't know if Underwood Dudley ever put it online, but at one point he did publish his collection under the title "The Trisectors" (978-0883855140). For every single failed trisection he provides a diagram, a brief description of the construction, and a measure of the error.

我不知道 Underwood Dudley 有没有把它放到网上过，但他确实曾以《The Trisectors》（978-0883855140）为书名出版过他的合集。对于每一个失败的三等分角方案，他都提供了一张图表、一段对作图过程的简要描述以及对误差的度量。
