I've been into _hinged_ dissections in woodworking for a while. This algorithm _isn't_ hinged, but it is cool to directly see the Wallace-Bolyai-Gerwain theorem in action.

Here's a video with more context! https://youtu.be/ysV6iF3Rmjo

You might enjoy Frederickson’s book on hinged dissections https://amzn.com/0521811929/
Add the title?

Edit: Many thanks. That does look like a great book.

Generally, in mathematical publishing, when someone refers to a book by the author's name, the title is (essentially) the topic.

Without clicking the link, I'd bet dollars to donuts the book is titled "Hinged Dissections", "Hinged Dissections: A Pivotal Analysis", "Hinged Dissections: Swing Sets", etc.

edit: it's "Hinged Dissections: Swinging and Twisting". I prefer "A Pivotal Analysis".

(When I commented above the author had not yet been added to parent comment. It was just an Amazon link. I suspect that's why it was getting downvotes.)
Thanks for asking for it, then! :)
Cheers :)
Not to mention the fact it's literally linked in the comment they're replying to.
Yeah, because I don't know how hyperlinks work, right? ;-P

It was getting greyed out from downvotes. I surmised that it was because it was only an Amazon link with no additional information. OP added info and comment is no longer greyed. Win?

That was really a great explanation! Thanks.
This is the kind of stuff I miss seeing on the good old days of HN
That’s pretty neat
