However the maths I used should be quite within the grasp of an honours
student in physical science or engineering. Tools of the trade. Although I
do wonder if people now use computer programs without a clue how they work.

At a brief perusal, I'd say it looks like an ideal opportunity to
extend my maths knowledge beyond the O-levels I did 45 years ago. And,
as an applications programmer, I can assure you that not only do our
users use programs without having a clue how they work, programmers
who inherit dreadfully-written [1] systems also don't have a clue how
they work, they just know that they almost always do.

[1] ie. any system composed of programs not written by them
