The question is, can you spot the moment where I realise (a) just how many pages of summation convention algebra I will have to do and (b) the number of biros I will wear out to get to the answer?
And yes, I am aware that "bla bla bla ⇒ result" does not constitute rigorous mathematical proof.
BluuurrrrghghghhHGhghGHGHGHHHHHHHHHHHHHHHHHHH.
EDIT Sorry, I now realise this isn't in the slightest bit funny. Long periods in the library tend to warp what I find amusing.

I solemnly swear not to write about summation convention ever again. Especially not in the context of trying to be funny.
I am so ashamed.
I've done pretty much the same thing before, but with "Tedious algebra => result". If you pretend you're doing it because the maths is so trivial and not because you're lazy or tired, it makes you feel really clever!
ReplyDeleteIndeed! I mean, I knew I could do it, I just reasoned that the c. 1 hour of my time it would take wasn't worth it for learning nothing.
ReplyDeleteBut yes, next time I shall just write "Trivial!", state the result and move on :-)
Reminds me of the remarkable P.T.Johnstone proof of Fermat's Last Theorem:
ReplyDeleteThere is a trivial bijection between the set of elliptic curves and the set of modular forms. The result follows.
Ahahaha! I had completely forgotten about that!
ReplyDeleteI did not enjoy his numbers and sets course... It was all 'trivial' bijections between things...
