I'm glad you've forwarded the message to the list, because I love that
comic. The clever thing is that it actually gets the maths right too.
Some of the notation is a bit strange compared to what I'm used to
(I've never seen anyone use a bare integral sign before, with no
integrand), and I think he skipped a line, but that's definitely one to
keep.
Thanks,
