I can imagine some students might sign up for this and find more maths
than they expected. Well, I suppose it's no bad thing to grind a bit
of rigourous thought into young minds.

FWIW One of the reasons I wrote the book was that most of the existing
alternative texts had far *more* maths per page, and less explanatory text!

The result was books which even *lecturers* failed to understand, but felt
"must be good" because it looked impressive. Example of the story of two
people coming out of a talk, one saying to the other: "He must be clever, I
didn't understand a word he said!" 8-]

Sadly, this also means that many of the textbooks I found on IT and also EM
contained erronious arguments or 'proofs' which had been duly copied from
one book to another. Presumably because generations of authors didn't
understand but assume it "must be correct".

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.
