Some time ago, I came across an anecdotal story about the "Big Book of Proofs" that God always keeps up in the heaven, which records valid proofs of all theorems in the world. A noted mathematician was quoted as saying that if he was to die tomorrow, the first thing he would do is to take a look at the book, since he had such burning questions about some math proofs.
Kindly let me know if you happen to know the source and the person's name; I would love to quote them in my writing. Thank you for your time and help.
