Really.  So the engineer who designed the apartment building I'm in at
the moment didn't know any physics, thought `tensor' was a scary math
term irrelevant to practical, real-world engineering, and will only read
books on engineering that replace the other scary technical term
`vector' with point-direction-value-thingy?  I think I'm going to sleep
under the stars tonight...

Um, no.  I try to avoid people as much as possible; computers at least
make sense.  Also anything else to do with the real world :)

Perhaps I should have said `completely ignorant'?  Or do you think that

  join . join = join . fmap join

is of the same level of theoretical depth as quantum orbital mechanics?

Again, do engineers know *what* stress is?  Do they understand terms
like `tensor'?  Those things are the rough equivalents of terms like
`monoid'.
