Function

I think he's referring to Wiles' rationale for writing the complicated proof of Fermat's Last Theorem. On that note I'd suppose that the proof itself is an explanation of his thought process . But then again.. the question was probably rhetorical haha.

That could be it. lol

I indeed meant Wiles's way too long proof about FLT. Retorical indeed

Had to find a subject for research competence for maths, wanted to do it about FLT, but my teacher didn't feel like letting me look into a +100 pages proof.. Wasn't my meaning, though.. But whatever.. Now it concerns Fermats little theorem
