Re: [math-fun] Draft of essay about two proofs of a rectangle tiling theorem

I would think the Devil's book should contain false proofs whose errors are so subtle that they could go undetected for decades, if not longer. Tom Hans Havermann writes:

CM: "I haven’t found a source for the Devil’s book ..."

In Shalosh B. Ekhad's "A Proof of Morley's Theorem (From The (Devil's) Book)" [mid-1990s] is written: "According to Doron Zeilberger, the devil(SC(?)), also has a notebook, that contains purely routine, albeit often long, proofs of all theorems."
