> The source I linked to above cites Mathematical Cranks by Underwood Dudley, but I couldn’t find it in the book.

I don't know why someone would make an AI slop fake of old mathematical crankery, but I think that has to be considered as a possibility. Especially given that the formula is being attributed to Dudley, who was actually cataloguing the nonsense of others.

(Also, a conventional Internet search tells me that Dudley was born in 1937, not 1912; and that rather than dying in 2005, he is still alive.)

(Perhaps Cook noticed these things and is too polite to point them out?)

It's hard to be totally sure, but I also don't think that's a picture of Dudley.
