"By the way, if you have any trisections or any works of mathematical cranks I would be most grateful to have copies. I have sought such things out for years, and my collection of analyzed trisections [...] is in it second hundred."
I would love to see that collection. Anyone knows if anything like that is available online?
- schoen 9y agoPer 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/dp/0883855143/ https://www.amazon.com/Trisectors-Spectrum-Underwood-Dudley/... and also https://www.amazon.com/Budget-Trisections-Underwood-Dudley/dp/1461264308/ 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 book there is actually just the first edition of the first book, and the title changed for the second edition.
- breadbox 9y agoI 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.
