Which should be read as:

Integral z-squared dz
from 1 to the cube root of 3
times the cosine
of three pi over 9
equals log of the cube root of ‘e’.

Note that this limerick relies for its rhyme on the American pronunciation of “z” as “zee”. For the “z = zed” half of the world, you can substitute in another letter such as “t”. What it all means is beyond me… however much I had of this in school is long forgotten. I’m much happier with the Mathematical limerick in an earlier blog post.

This limerick appears in a book by Devine and Cohen, ‘Absolute Zero Gravity‘, but it is not clear that any of the poems, jokes and puzzles collected in it actually originate with the authors, as they are all “collected” but unattributed.
