This seems to be the case for music as well. Many musicians and/or
producers end up writing things in the same handful of song
structures, chord progressions, etc ...

Ah, but that's called artistic inspiration! Classical music composers borrowed from each other. Mozart and Haydn often sound alike, though one can hear subtle differences if one listens carefully.

Pretty much anything else
which deviates significantly from the "norm" of a hit song, is largely
turned down by the corporate music machine business. (Sometimes a
small indie record label may express interest in avant garde stuff
which don't fit into the "norm").

I rarely listen to anything others than classical or opera, though I do have some guilty pleasures in my CD library--most of it stuff from my early student days.



Basically after all the "calculus" stuff is done, frequently what's
left is a huge algebraic mess to work out to a final expression.

That sounds like what happens when one takes an algorithm and converts it
into an equivalent mathematical expression. Often, there are lots of
summations, absolute values, and matrices.


That's very much what happens in long messy calculations, especially
if there's a recursive algorithm involved. For particle physics
calculations, some calculations can easily involve hundreds of
thousands of algebraic terms (if not millions of terms). These days
they just do them using symbolic algebra type computer programs like
Mathematica.

So, if one doesn't have Mathematica on hand, one can't understand what the equations are saying? No, thanks. I prefer using pencil and paper.


So far nobody has really found an easy way to do these long messy
particle physics calculations. In some sense, higher order
calculations in quantum field theory still seems to be stuck in a
"Rube Goldberg" phase of messiness, with very little relief in sight.
Maybe some day an Einstein-like genius will find an easy way to do
these sort of calculations by hand.
