It looks like faux-calculus for the purpose of humor. At first glance it seems to be a rotational calculation around a non-axis line, but there's no reason for it to use silly symbols like omega as far as I know. Also, I'm not used to there being integrals of summations--it seems a little redundant. Then again, I haven't taken calculus in a year and might be a little rusty. =/ Right now I'm in Statistics (bore of bores; at least calculus was interesting).
