I think he is laughting at us all, and just seeing what can be gotten away
with.
Nobody with an engineering degree would ever write something like the
following:

"Calculus is based on homogenous materials or planes where you can
refer dy/dx to some thing aproaching zero. In the case of using this
aproach where the antenna diameter aproaches zero this is an invalid
aproach for accuracy but O.K. for aproximations. So much for the
foibles of theoretical mathematics".

You know that the term of dy/dx is absent of metrics unless limits are
applied.
If the object is to measure the plane at hand it obviously must
represent a homogeneous plane
when the limits applied. This was established long before I was born
so it was not I who made it up
Laugh away it is good for you.
