Thanks Axel
Regarding the second approach;
I have read
* Paul Graham's "On Lisp"
* Siebel's "Practical Common Lisp"
so have seen things like "gensym" and why has to be so.

Reality is, with very not-advanced lisp basics I seem to do well.

In my world of melting and shaping metal, there seems to be something
good about the working environment of equations and explanations in one
document.  It seems to facilitate a person developing their thoughts.

This seems to be the biggest issue - what the environment makes readily
and enjoyably achievable.

In recent years

* every beam calculation I want to do
  (Euler-Bernoulli beam - derived 1750's; applied eg. Eiffel 1880's-ish)
  which I do use frequently in my welding and engineering work

* a 1-D computer-numerical solution for heat-flow which proves a useful
  "nutcracker" for considering what's going on where the issue is
  conductive heat transfer

* in mineral processing (considering processing metal ores - tin,
  copper, etc) I can run through calculations actually feeling very
  happy

Mineral processing was last new application, a couple of months ago.
I'm surrounded by abandoned mines here - some of the iconic images of
Cornwall.  With for me the crucial thing being that tin-mining is
restarting here.  There's also lithium here - efforts to work that.
None of these metals "self-extract" from the "run-of-mine" ore.
Hence mineral processing as an expertise.

Thing is, those happily-done calculations enabled me to see the
twists-and-turns the author, with decades of experience of mineral
processing, could throw at you to get you to think through the issue.
Layers deeper than the text alone could take you.

I had to visualise the minerals and mineral streams, then draw sketches
which were my "model", then derive the maths (concurred with the
author's equations) - then write the elisp functions and get the
answers.
No immediate jobs so having to get back to welding - but could return to
remind of the logical path which worked for me, in those files, whenever.

These were all "trivial" algebraic expressions, in computing terms.

I appreciate you showing me
where I could take my computing
if that juncture came.

Regards,
Rich Smith
