OK, when I use the Wiki Source link when View-ing the docstring for
scipy.absolute, e.g., and search the resulting page for absolute, it's not
found at all - I'm assuming this is an example of where the numpy function
has simply been imported into the scipy namespace, and that similar results
indicate a similar situation...

Mathematician: noun, someone who disavows certainty when their uncertainty
set is non-empty, even if that set has measure zero.

Hope: noun, that delusive spirit which escaped Pandora's jar and, with her
lies, prevents mankind from committing a general suicide.  (As interpreted
by Robert Graves)
