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.
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 love skipping.|
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.
